- - - Introduction - - The &os; project uses the - Perforce version control system to - manage experimental projects that are not ready for the main - Subversion repository. - - - Availability, Documentation, and Resources - - While Perforce is a commercial - product, the client software for interacting with the server - is freely available from Perforce. It can be easily installed - on &os; via the devel/p4 port or can be - downloaded from the Perforce web - site at http://www.perforce.com/downloads/helix#clients, - which also offers client applications for other OS's. - - While there is a GUI client available, most people use the - command line application called p4. This - document is written from the point of view of using this - command. - - Detailed documentation is available online at https://www.perforce.com/perforce/doc.current/manuals/p4guide/index.html. - - Reading the Perforce User's Guide and - Perforce Command Reference is highly - recommended. The p4 application - also contains an extensive amount of online help accessible - via p4 help. - - The &os; Perforce server is - hosted on perforce.freebsd.org, port - 1666. The repository is browsable online - at http://p4web.freebsd.org. - - - - - Getting Started - - The first step to using Perforce - is to obtain an account on the server. If you already have a - FreeBSD.org - account, log into freefall, run the following - command, and enter a password that is not the same as your &os; - login or any other SSH passphrase: - - &prompt.user; /usr/local/bin/p4newuser - - Of course if you do not have a FreeBSD.org account, you - will need to coordinate with your sponsor. - - - An email will be sent to your &os; address that contains - the password you specified above in cleartext. Be sure to - change the password once your - Perforce account has been - created! - - - The next step is to set the environment variables that - p4 needs, and verify that it can connect to - the server. The P4PORT variable is required to - be set for all operations, and specifies the appropriate - Perforce server to talk to. For the - &os; project, set it like so: - - &prompt.user; export P4PORT=perforce.freebsd.org:1666 - - - Users with shell access on the FreeBSD.org cluster may - wish to tunnel the Perforce - client-server protocol via an SSH tunnel, in which case the - above string should be set to - localhost. - - - The &os; server also requires that the P4USER - and P4PASSWD variables be set. Use the username - and password from above, like so: - - &prompt.user; export P4USER=username -&prompt.user; export P4PASSWD=password - - Test that this works by running the following - command: - - &prompt.user; p4 info - - This should return a list of information about the server. - If it does not, check that you have the P4PORT - variable set correctly. - - - - Clients - - Perforce provides access to the - repository and tracks state on a per-client basis. In - Perforce terms, a client is a - specification that maps files and directories from the - repository to the local machine. Each user can have multiple - clients, and each client can access different or overlapping - parts of the repository. The client also specifies the root - directory of the file tree that it maps, and it specifies the - machine that the tree lives on. Thus, working on multiple - machines requires that multiple clients be used. - - Clients may be accessed via p4 client. - Running this command with no arguments will bring up a client - template in an editor, allowing you to create a new client for - your work. The important fields in this template are explained - below: - - - - Client: - - - This is the name of the client spec. It can be - anything you want, but it must be unique within the - Perforce server. A naming - convention that is commonly used is - username_machinename, - which makes it easy to identify clients when browsing - them. A default name will be filled in that is just the - machine name. - - - - - Description: - - - This can contain a simple text description to help - identify the client. - - - - - Root: - - - This is the local directory that will serve as the - root directory of all the files in the client mapping. - This should be a unique location in your filesystem that - does not overlap with other files or - Perforce clients. - - - - - Options: - - - Most of the default options are fine, though it is - usually a good idea to make sure that the - and - options are present and do not have a - no prefix on them. Details about each - option are in the Perforce - docs. - - - - - LineEnd: - - - This handles CR-LF conversions and should be left to - the default unless you have special needs for it. - - - - - View: - - - This is where the server-to-local file mappings go. - The default is - - //depot/... //client/... - - This will map the entire - Perforce repository to the - Root directory of your client. - DO NOT USE THIS DEFAULT! The &os; - repo is huge, and trying to map and sync it all will take - an enormous amount of resources. Instead, only map the - section of the repo that you intend to work on. For - example, there is the smpng project tree at - //depot/projects/smpng. A mapping - for this might look like: - - //depot/projects/smpng/... //client/... - - The ... should be taken literally. - It is a Perforce idiom for - saying this directory and all files and directories - below it. - - A Perforce view can contain multiple - mappings. Say you want to map in both the SMPng tree and - the NFS tree. Your View might look like: - - //depot/projects/smpng/... //client/smpng/... - //depot/projects/nfs/... //client/nfs/... - - Remember that the client is - the name of the client that was specified in the - Client section, but in the - View it also resolves to the directory - that was specified in the Root - section. - - Also note that the same file or directory cannot be - mapped multiple times in a single view. The following is - illegal and will produce undefined results: - - //depot/projects/smpng/... //client/smpng-foo/... - //depot/projects/smpng/... //client/smpng-bar/... - - Views are a tricky part of the learning experience - with Perforce, so do not be - afraid to ask questions. - - - - - Existing clients can be listed via p4 - clients. They can be viewed without being modified - via p4 client -o - clientname. - - Whenever you are interacting with files in - Perforce, the P4CLIENT - environment variable must be set to the name of the client that - you are using, like so: - - &prompt.user; export P4CLIENT=myclientname - - Note that client mappings in the repository are not - exclusive; multiple clients can map in the same part of the - repository. This allows multiple people to access and modify - the same parts of the repository, allowing a team of people to - work together on the same code. - - - - Syncing - - Once you have a client specification defined and the - P4CLIENT variable set, the next step is to pull - the files for that client down to your local machine. This is - done with p4 sync, which instructs - Perforce to synchronize the local - files in your client with the repository. The first time it - runs, it will download all of the files. Subsequent runs will - only download files that have changed since the previous run. - This allows you to stay in sync with others whom you might be - working with. - - Sync operations only work on files that the - Perforce server knows has changed. - If you change or delete a file locally without informing the - server, doing a sync will not bring it back. However, doing a - p4 sync -f will unconditionally sync all - files, regardless of their state. This is useful for resolving - problems where you think that your tree might be corrupt. - - You can sync a subset of your tree or client by specifying a - relative path to the sync command. For example, to only sync - the ufs directory of the - smpng project, you might do the - following: - - &prompt.user; cd projectroot/smpng -&prompt.user; p4 sync src/sys/ufs/... - - Specifying a local relative path works for many other - p4 commands. - - - - Branches - - One of the strongest features of - Perforce is branching. Branches are - very cheap to create, and moving changes between related - branches is very easy (as will be explained later). Branches - also allow you to do very experimental work in a sandbox-like - environment, without having to worry about colliding with others - or destabilizing the main tree. They also provide insulation - against mistakes while learning the - Perforce system. With all of these - benefits, it makes sense for each project to have its own - branch, and we strongly encourage that with &os;. Frequent - submits of changes to the server are also encouraged. - - Similar to Subversion, the - Perforce repository (the - depot) is a single flat tree. Every file, - whether a unique creation or a derivative from a branch, is - accessible via a simple path under the server - //depot directory. When you create a - branch, all you are doing is creating a new path under the - //depot. This is in sharp contrast to - systems like CVS, where each branch lives in the same path as - its parent. With Perforce, the - server tracks the relationship between the files in the parent - and child, but the files themselves live under their own - paths. - - The first step to creating a branch is to create a branch - specification. This is similar to a client specification, but - is created via the command p4 branch - branchname. - - The following important fields are explained: - - - - Branch - - - The name of the branch. It can be any name, but must - be unique within the repository. The common convention in - &os; is to use - username_projectname. - - - - - Description - - - This can hold a simple text description to describe - the branch. - - - - - View - - - This is the branch mapping. Instead of mapping from - the depot to the local machine like a client map, it maps - between the branch parent and branch child in the depot. - For example, you might want to create a branch of the - smpng project. The mapping might look like: - - //depot/projects/smpng/... //depot/projects/my-super-smpng/... - - Or, you might want to create a brand new branch off of - the stock &os; sources: - - //depot/vendor/freebsd/... //depot/projects/my-new-project/... - - This will map the &os; HEAD tree to your new - branch. - - - - - Creating the branch spec only saves the spec itself in the - server, it does not modify the depot or change any files. The - directory that you specified in the branch is empty on the - server until you populate it. - - To populate your branch, first edit your client with - p4 client and make sure that the branch - directory is mapped in your client. You might need to add a - View line like: - - //depot/projects/my-new-project/... //myclient/my-new-project/... - - The next step is to run p4 integrate, as - described in the next section. - - - - Integrations - - Integration is the term used by - Perforce to describe the action of - moving changes from one part of the depot to another. It is - most commonly done in conjunction with creating and maintaining - branches. An integration is done when you want to initially - populate a branch, and it is done when you want to move - subsequent changes in the branch from the parent to the child, - or from the child to the parent. A common example of this is - periodically integrating changes from the vendor &os; tree to - your child branch tree, allowing you to keep up to date with - changes in the &os; tree. The - Perforce server tracks the changes in - each tree and knows when there are changes that can be - integrated from one tree to another. - - The common way to do an integration is with the following - command: - - &prompt.user; p4 integrate -b branchname - - branchname is the name given to a - branch spec, as discussed in the previous section. This command - will instruct Perforce to look for - changes in the branch parent that are not yet in the child. - From those changes it will prepare a list of diffs to move. If - the integration is being done for the first time on a branch - (for example doing an initial population operation), then the - parent files will simply be copied to the child location on the - local machine. - - Once the integration operation is done, you must run - p4 resolve to accept the changes and resolve - possible conflicts. Conflicts can arise from overlapping - changes that happened in both the parent and child copy of a - file. Usually, however, there are no conflicts, and - Perforce can quickly figure out how - to merge the changes together. Use the following commands to do - a resolve operation: - - &prompt.user; p4 resolve -as -&prompt.user; p4 resolve - - The first invocation will instruct - Perforce to automatically merge the - changes together and accept files that have no conflicts. The - second invocation will allow you to inspect each file that has a - possible conflict and resolve it by hand if needed. - - Once all of the integrated files have been resolved, they - need to be committed back to the repository. This is done via - p4 submit, explained in the next - section. - - - - Submit - - Changes that are made locally should be committed back to - the Perforce server for safe keeping - and so that others can access them. This is done via - p4 submit. When you run this command, it - will open up a submit template in an editor. &os; has a custom - template, and the important fields are described below: - - Description: - <enter description here> - PR: - Submitted by: - Reviewed by: - Approved by: - Obtained from: - MFP4 after: - - It is good practice to provide at least 2-3 sentences that - describe what the changes are that you are submitting. You - should say what the change does, why it was done that way or - what problem is solves, and what APIs it might change or other - side effects it might have. This text should replace the - <enter description here> line in the - template. You should wrap your lines and start each line with a - TAB. The tags below it are &os;-specific and can be removed if - not needed. - - Files: - - This is automatically populated with all of the files in - your client that were marked in the add, delete, integrate, or - edit states on the server. It is always a very good idea to - review this list and remove files that might not be ready - yet. - - Once you save the editor session, the submit will happen to - the server. This also means that the local copies of the - submitted files will be copied back to the server. If anything - goes wrong during this process, the submit will be aborted, and - you will be notified that the submit has been turned into a - changelist that must be corrected and re-submitted. Submits are - atomic, so if one file fails, the entire submit is - aborted. - - Submits cannot be reverted, but they can be aborted while in - the editor by exiting the editor without changing the - Description text. - Perforce will complain about this the - first time you do it and will put you back in the editor. - Exiting the editor the second time will abort the operation. - Reverting a submitted change is very difficult and is best - handled on a case-by-case basis. - - - - Editing - - The state of each file in the client is tracked and saved on - the server. In order to avoid collisions from multiple people - working on the same file at once, - Perforce tracks which files are - opened for edit, and uses this to help with submit, sync, and - integration operations later on. - - To open a file for editing, use p4 edit - like so: - - &prompt.user; p4 edit filename - - This marks the file on the server as being in the - edit state, which then allows it to be - submitted after changes are made, or marks it for special - handling when doing an integration or sync operation. Note that - editing is not exclusive in Perforce. - Multiple people can have the same file in the edit state (you - will be informed of others when you run - edit), and you can submit your changes even - when others are still editing the file. - - When someone else submits a change to a file that you are - editing, you will need to resolve his changes with yours before - your submit will succeed. The easiest way to do this is to - either run a p4 sync or p4 - submit and let it fail with the conflict, then run - p4 resolve to manually resolve and accept his - changes into your copy, then run p4 submit to - commit your changes to the repository. - - If you have a file open for edit and you want to throw away - your changes and revert it to its original state, run - p4 revert like so: - - &prompt.user; p4 revert filename - - This resyncs the file to the contents of the server, and - removes the edit attribute from the server. Any local changes - that you had will be lost. This is quite useful when you have a - made changes to a file but later decide that you do not want to - keep them. - - When a file is synced, it is marked read-only in the - filesystem. When you tell the server to open it for editing, it - is changed to read-write on the filesystem. While these - permissions can easily be overridden by hand, they are meant to - gently remind you that you should being using p4 - edit. Files that have local changes but are not in - the edit state may get overwritten when doing a p4 - sync. - - - - Changes, Descriptions, and History - - Changes to the Perforce depot can - be listed via p4 changes. This will provide - a brief description of each change, who made the change, and - what its change number was. A change can be examined in detail - via p4 describe - changenumber. This will - provide the submit log and the diffs of the actual - change. - - Commonly, p4 describe is used in one - of three ways: - - - - p4 describe -s - CHANGE - - - List a short description of changeset - CHANGE, including the commit log of - the particular changeset and a list of the files it - affected. - - - - - p4 describe -du - CHANGE - - - List a description of changeset - CHANGE, including the commit log of - the particular changeset, a list of the files it affected - and a patch for each modified file, in a format similar to - unified diff patches (but not exactly the - same). - - - - - p4 describe -dc - CHANGE - - - List a description of changeset - CHANGE, including the commit log of - the particular changeset, a list of the files it affected - and a patch for each modified file, in a format similar to - context diff patches (but not exactly the - same). - - - - - The history of a file, including all submits, integrations, - and branches of it will be shown by p4 filelog - filename. - - - - Diffs - - There are two methods of producing file diffs in - Perforce, either against local - changes that have not been submitted yet, or between two trees - (or within a branch) in the depot. These are done with - different commands, and - : - - - - p4 diff - - - This generates a diff of the local changes to files in - the edit state. The and - flags can be used to create unified - or context diffs, respectively, or the - P4DIFF environment variable can be set to a - local diff command to be used instead. It is a very good - idea to use this command to review your changes before - submitting them. - - - - - p4 diff2 - - - This creates a diff between arbitrary files in the - depot, or between files specified in a branch spec. The - diff operation takes place on the server, so - P4DIFF variable has no effect, though the - and flags do - work. The two forms of this command are: - - &prompt.user; p4 diff2 -b branchname - - and - - &prompt.user; p4 diff2 //depot/path1 //depot/path2 - - - - - In all cases the diff will be written to the standard - output. Unfortunately, Perforce - produces a diff format that is slightly incompatible with the - traditional Unix diff and patch tools. Using the - P4DIFF variable to point to the real &man.diff.1; - tool can help this, but only for p4 diff. - The output of command must be - post-processed to be useful (the flag of - will produce unified diffs that are - somewhat compatible, but it does not include files that have - been added or deleted). There is a post-processing script at: - https://svnweb.freebsd.org/base/head/tools/tools/perforce/awkdiff?view=co. - - - - Adding and Removing Files - - Integrating a branch will bring existing files into your - tree, but you may still want to add new files or remove existing - ones. Adding files is easily done be creating the file and then - running p4 add like so: - - &prompt.user; p4 add filename - - If you want to add a whole tree of files, run a command - like: - - &prompt.user; find . -type f | xargs p4 add - - - Perforce can track UNIX - symlinks too, so you can probably use - \! -type d as the - matching expression in &man.find.1; above. We do not commit - symlinks into the source tree of &os; though, so this should - not be necessary. - - - Doing a p4 submit will then copy the file - to the depot on the server. It is very important to only add - files, not directories. Explicitly adding a directory will - cause Perforce to treat it like a - file, which is not what you want. - - Removing a file is just as easy with the - p4 delete command like so: - - &prompt.user; p4 delete filename - - This will mark the file for deletion from the depot the next - time that a submit is run. It will also remove the local copy - of the file, so beware. - - Of course, deleting a file does not actually remove it from - the repository. - - Deleted files can be resurrected by syncing them to a prior - version. The only way to permanently remove a file is to use - p4 obliterate. This command is irreversible - and expensive, so it is only available to those with admin - access. - - - - Working with Diffs - - Sometimes you might need to apply a diff from another source - to a tree under Perforce control. If - it is a large diff that affects lots of files, it might be - inconvenient to manually run p4 edit on each - file. There is a trick for making this easier. First, make - sure that no files are open on your client and that your tree is - synced and up to date. Then apply the diff using the normal - tools, and coerce the permissions on the files if needed. Then - run the following commands: - - &prompt.user; p4 diff -se ... | xargs p4 edit -&prompt.user; p4 diff -sd ... | xargs p4 delete -&prompt.user; find . -type f | xargs p4 add - - The first command tells Perforce - to look for files that have changed, even if they are not open. - The second command tells Perforce to - look for files that no longer exist on the local machine but do - exist on the server. The third command then attempts to add all - of the files that it can find locally. This is a very - brute-force method, but it works because - Perforce will only add the files that - it does not already know about. The result of running these - commands will be a set of files that are opened for edit, - removal, or add, as appropriate. - - Verify the active changelist with: - - &prompt.user; p4 changelist -&prompt.user; p4 diff -du - - and just do a p4 submit after - that. - - - - Renaming Files - - Perforce does not have a built-in - way of renaming files or moving them to a different part of the - tree. Simply copying a file to the new location, doing a - p4 add on it, and a p4 - delete on the old copy, works, but does not preserve - change history of the file. This can make future integrations - with parents and children very bumpy, in fact. A better method - of dealing with this is to do a one-time, in-tree integration, - like so: - - &prompt.user; p4 integrate -i oldfile newfile -&prompt.user; p4 resolve -&prompt.user; p4 delete oldfile -&prompt.user; p4 submit - - The integration will force - Perforce to keep a record of the - relationship between the old and new names, which will assist it - in future integrations. The flag tells it - that it is a baseless integration, meaning that - there is no branch history available for it to use in the - integration. That is perfect for an integration like this, but - should not be used for normal branch-based integrations. - - - - Interactions Between &os; Subversion and Perforce - - The &os; Perforce and - Subversion repositories are - completely separate. However, changes to Subversion are tracked - at near-real-time in Perforce. Every - 2 minutes, the Subversion server is polled for updates in the - HEAD branch, and those updates are committed to - Perforce in the - //depot/vendor/freebsd/... tree. This tree - is then available for branching and integrating to derivative - projects. Any project that directly modifies that &os; source - code should have this tree as its branch parent (or grandparent, - depending on the needs), and periodic integrations and syncs - should be done so that your tree stays up to date and avoids - conflicts with mainline development. - - The bridge between Subversion and - Perforce is one-way; changes to - Subversion will be reflected in - Perforce, but changes in Perforce - will not be reflected in Subversion. - - - - Offline Operation - - One weakness of Perforce is that - it assumes that network access to the server is always - available. Most state, history, and metadata is saved on the - server, and there is no provision for replicating the server - like there is with SVN. It is possible to run a proxy server, - but it only provides very limited utility for offline - operation. - - The best way to work offline is to make sure that your - client has no open files and is fully synced before going - offline. Then when editing a file, manually change the - permissions to read-write. When you get back online, run the - commands listed in the to - automatically identify files that have been edited, added, and - removed. It is quite common to be surprised by - Perforce overwriting a locally - changed file that was not opened for edit, so be extra vigilant - with this. - - - - Notes for Google Summer of Code - - Most &os; projects under the Google Summer of Code program - are located on the &os; Perforce - server under one of the following locations: - - - - //depot/projects/soc2005/project-name/... - - - //depot/projects/soc2006/project-name/... - - - //depot/projects/soc2007/project-name/... - - - //depot/projects/soc2008/project-name/... - - - - The project mentor is responsible for choosing a suitable - project name and getting the student going with - Perforce. - - Access to the &os; Perforce - server does not imply access to subversion, though we happily - encourage all students to consider - joining the project when the time is appropriate. - -

This error means that the ssh kpasswd.freebsd.org method shown above must be used first to initialize the Kerberos account. Commit Bit Types The &os; repository has a number of components which, when combined, support the basic operating system source, documentation, third party application ports infrastructure, and various maintained utilities. When &os; commit bits are allocated, the areas of the tree where the bit may be used are specified. Generally, the areas associated with a bit reflect who authorized the allocation of the commit bit. Additional areas of authority may be added at a later date: when this occurs, the committer should follow normal commit bit allocation procedures for that area of the tree, seeking approval from the appropriate entity and possibly getting a mentor for that area for some period of time. Committer Type Responsible Tree Components src core@ src/, doc/ subject to appropriate review doc doceng@ doc/, ports/, src/ documentation ports portmgr@ ports/ Commit bits allocated prior to the development of the notion of areas of authority may be appropriate for use in many parts of the tree. However, common sense dictates that a committer who has not previously worked in an area of the tree seek review prior to committing, seek approval from the appropriate responsible party, and/or work with a mentor. Since the rules regarding code maintenance differ by area of the tree, this is as much for the benefit of the committer working in an area of less familiarity as it is for others working on the tree. Committers are encouraged to seek review for their work as part of the normal development process, regardless of the area of the tree where the work is occurring. Policy for Committer Activity in Other Trees All committers may modify base/head/share/misc/committers-*.dot, base/head/usr.bin/calendar/calendars/calendar.freebsd, and ports/head/astro/xearth/files. doc committers may commit documentation changes to src files, such as man pages, READMEs, fortune databases, calendar files, and comment fixes without approval from a src committer, subject to the normal care and tending of commits. Any committer may make changes to any other tree with an "Approved by" from a non-mentored committer with the appropriate bit. Committers can acquire an additional bit by the usual process of finding a mentor who will propose them to core, doceng, or portmgr, as appropriate. When approved, they will be added to 'access' and the normal mentoring period will ensue, which will involve a continuing of Approved by for some period. "Approved by" is only acceptable from non-mentored src committers -- mentored committers can provide a "Reviewed by" but not an "Approved by". Subversion Primer New committers are assumed to already be familiar with the basic operation of Subversion. If not, start by reading the Subversion Book. Introduction The &os; source repository switched from CVS to Subversion on May 31st, 2008. The first real SVN commit is r179447. The &os; doc/www repository switched from CVS to Subversion on May 19th, 2012. The first real SVN commit is r38821. The &os; ports repository switched from CVS to Subversion on July 14th, 2012. The first real SVN commit is r300894. Subversion can be installed from the &os; Ports Collection by issuing these commands: &prompt.root; pkg install subversion Getting Started There are a few ways to obtain a working copy of the tree from Subversion. This section will explain them. Direct Checkout The first is to check out directly from the main repository. For the src tree, use: &prompt.user; svn checkout svn+ssh://repo.freebsd.org/base/head /usr/src For the doc tree, use: &prompt.user; svn checkout svn+ssh://repo.freebsd.org/doc/head /usr/doc For the ports tree, use: &prompt.user; svn checkout svn+ssh://repo.freebsd.org/ports/head /usr/ports Though the remaining examples in this document are written with the workflow of working with the src tree in mind, the underlying concepts are the same for working with the doc and the ports tree. Ports related Subversion operations are listed in . The above command will check out a CURRENT source tree as /usr/src/, which can be any target directory on the local filesystem. Omitting the final argument of that command causes the working copy, in this case, to be named head, but that can be renamed safely. svn+ssh means the SVN protocol tunnelled over SSH. The name of the server is repo.freebsd.org, base is the path to the repository, and head is the subdirectory within the repository. If your &os; login name is different from the login name used on the local machine, either include it in the URL (for example svn+ssh://jarjar@repo.freebsd.org/base/head), or add an entry to ~/.ssh/config in the form: Host repo.freebsd.org User jarjar This is the simplest method, but it is hard to tell just yet how much load it will place on the repository. The svn diff does not require access to the server as SVN stores a reference copy of every file in the working copy. This, however, means that Subversion working copies are very large in size. Checkout from a Mirror Check out a working copy from a mirror by substituting the mirror's URL for svn+ssh://repo.freebsd.org/base. This can be an official mirror or a mirror maintained by using svnsync. There is a serious disadvantage to this method: every time something is to be committed, a svn relocate to the master repository has to be done, remembering to svn relocate back to the mirror after the commit. Also, since svn relocate only works between repositories that have the same UUID, some hacking of the local repository's UUID has to occur before it is possible to start using it. The hassle of a local svnsync mirror probably is not worth it unless the network connectivity situation or other factors demand it. If it is needed, see the end of this chapter for information on how to set one up. <literal>RELENG_*</literal> Branches and General Layout In svn+ssh://repo.freebsd.org/base, base refers to the source tree. Similarly, ports refers to the ports tree, and so on. These are separate repositories with their own change number sequences, access controls and commit mail. For the base repository, HEAD refers to the -CURRENT tree. For example, head/bin/ls is what would go into /usr/src/bin/ls in a release. Some key locations are: /head/ which corresponds to HEAD, also known as -CURRENT. /stable/n which corresponds to RELENG_n. /releng/n.n which corresponds to RELENG_n_n. /release/n.n.n which corresponds to RELENG_n_n_n_RELEASE. /vendor* is the vendor branch import work area. This directory itself does not contain branches, however its subdirectories do. This contrasts with the stable, releng and release directories. /projects and - /user feature a branch work area, - like in Perforce. As above, the + /user feature a branch work area. + As above, the /user directory does not contain branches itself. &os; Documentation Project Branches and Layout In svn+ssh://repo.freebsd.org/doc, doc refers to the repository root of the source tree. In general, most &os; Documentation Project work will be done within the head/ branch of the documentation source tree. &os; documentation is written and/or translated to various languages, each in a separate directory in the head/ branch. Each translation set contains several subdirectories for the various parts of the &os; Documentation Project. A few noteworthy directories are: /articles/ contains the source code for articles written by various &os; contributors. /books/ contains the source code for the different books, such as the &os; Handbook. /htdocs/ contains the source code for the &os; website. &os; Ports Tree Branches and Layout In svn+ssh://repo.freebsd.org/ports, ports refers to the repository root of the ports tree. In general, most &os; port work will be done within the head/ branch of the ports tree which is the actual ports tree used to install software. Some other key locations are: /branches/RELENG_n_n_n which corresponds to RELENG_n_n_n is used to merge back security updates in preparation for a release. /tags/RELEASE_n_n_n which corresponds to RELEASE_n_n_n represents a release tag of the ports tree. /tags/RELEASE_n_EOL represents the end of life tag of a specific &os; branch. Daily Use This section will explain how to perform common day-to-day operations with Subversion. Help SVN has built in help documentation. It can be accessed by typing: &prompt.user; svn help Additional information can be found in the Subversion Book. Checkout As seen earlier, to check out the &os; head branch: &prompt.user; svn checkout svn+ssh://repo.freebsd.org/base/head /usr/src At some point, more than just HEAD will probably be useful, for instance when merging changes to stable/7. Therefore, it may be useful to have a partial checkout of the complete tree (a full checkout would be very painful). To do this, first check out the root of the repository: &prompt.user; svn checkout --depth=immediates svn+ssh://repo.freebsd.org/base This will give base with all the files it contains (at the time of writing, just ROADMAP.txt) and empty subdirectories for head, stable, vendor and so on. Expanding the working copy is possible. Just change the depth of the various subdirectories: &prompt.user; svn up --set-depth=infinity base/head &prompt.user; svn up --set-depth=immediates base/release base/releng base/stable The above command will pull down a full copy of head, plus empty copies of every release tag, every releng branch, and every stable branch. If at a later date merging to 7-STABLE is required, expand the working copy: &prompt.user; svn up --set-depth=infinity base/stable/7 Subtrees do not have to be expanded completely. For instance, expanding only stable/7/sys and then later expand the rest of stable/7: &prompt.user; svn up --set-depth=infinity base/stable/7/sys &prompt.user; svn up --set-depth=infinity base/stable/7 Updating the tree with svn update will only update what was previously asked for (in this case, head and stable/7; it will not pull down the whole tree. Decreasing the depth of a working copy is not possible. Anonymous Checkout It is possible to anonymously check out the &os; repository with Subversion. This will give access to a read-only tree that can be updated, but not committed back to the main repository. To do this, use: &prompt.user; svn co https://svn.FreeBSD.org/base/head /usr/src More details on using Subversion this way can be found in Using Subversion. Updating the Tree To update a working copy to either the latest revision, or a specific revision: &prompt.user; svn update &prompt.user; svn update -r12345 Status To view the local changes that have been made to the working copy: &prompt.user; svn status To show local changes and files that are out-of-date do: &prompt.user; svn status --show-updates Editing and Committing - Unlike Perforce, SVN does not need to + SVN does not need to be told in advance about file editing. To commit all changes in the current directory and all subdirectories: &prompt.user; svn commit To commit all changes in, for example, lib/libfetch/ and usr/bin/fetch/ in a single operation: &prompt.user; svn commit lib/libfetch usr/bin/fetch There is also a commit wrapper for the ports tree to handle the properties and sanity checking the changes: &prompt.user; /usr/ports/Tools/scripts/psvn commit Adding and Removing Files Before adding files, get a copy of auto-props.txt (there is also a ports tree specific version) and add it to ~/.subversion/config according to the instructions in the file. If you added something before reading this, use svn rm --keep-local for just added files, fix your config file and re-add them again. The initial config file is created when you first run a svn command, even something as simple as svn help. Files are added to a SVN repository with svn add. To add a file named foo, edit it, then: &prompt.user; svn add foo Most new source files should include a $&os;$ string near the start of the file. On commit, svn will expand the $&os;$ string, adding the file path, revision number, date and time of commit, and the username of the committer. Files which cannot be modified may be committed without the $&os;$ string. Files can be removed with svn remove: &prompt.user; svn remove foo Subversion does not require deleting the file before using svn rm, and indeed complains if that happens. It is possible to add directories with svn add: &prompt.user; mkdir bar &prompt.user; svn add bar Although svn mkdir makes this easier by combining the creation of the directory and the adding of it: &prompt.user; svn mkdir bar Like files, directories are removed with svn rm. There is no separate command specifically for removing directories. &prompt.user; svn rm bar Copying and Moving Files This command creates a copy of foo.c named bar.c, with the new file also under version control and with the full history of foo.c: &prompt.user; svn copy foo.c bar.c This is usually preferred to copying the file with cp and adding it to the repository with svn add because this way the new file does not inherit the original one's history. To move and rename a file: &prompt.user; svn move foo.c bar.c Log and Annotate svn log shows revisions and commit messages, most recent first, for files or directories. When used on a directory, all revisions that affected the directory and files within that directory are shown. svn annotate, or equally svn praise or svn blame, shows the most recent revision number and who committed that revision for each line of a file. Diffs svn diff displays changes to the working copy. Diffs generated by SVN are unified and include new files by default in the diff output. svn diff can show the changes between two revisions of the same file: &prompt.user; svn diff -r179453:179454 ROADMAP.txt It can also show all changes for a specific changeset. This command shows what changes were made to the current directory and all subdirectories in changeset 179454: &prompt.user; svn diff -c179454 . Reverting Local changes (including additions and deletions) can be reverted using svn revert. It does not update out-of-date files, but just replaces them with pristine copies of the original version. Conflicts If an svn update resulted in a merge conflict, Subversion will remember which files have conflicts and refuse to commit any changes to those files until explicitly told that the conflicts have been resolved. The simple, not yet deprecated procedure is: &prompt.user; svn resolved foo However, the preferred procedure is: &prompt.user; svn resolve --accept=working foo The two examples are equivalent. Possible values for --accept are: working: use the version in your working directory (which one presumes has been edited to resolve the conflicts). base: use a pristine copy of the version you had before svn update, discarding your own changes, the conflicting changes, and possibly other intervening changes as well. mine-full: use what you had before svn update, including your own changes, but discarding the conflicting changes, and possibly other intervening changes as well. theirs-full: use the version that was retrieved when you did svn update, discarding your own changes. Advanced Use Sparse Checkouts SVN allows sparse, or partial checkouts of a directory by adding to a svn checkout. Valid arguments to are: empty: the directory itself without any of its contents. files: the directory and any files it contains. immediates: the directory and any files and directories it contains, but none of the subdirectories' contents. infinity: anything. The --depth option applies to many other commands, including svn commit, svn revert, and svn diff. Since --depth is sticky, there is a --set-depth option for svn update that will change the selected depth. Thus, given the working copy produced by the previous example: &prompt.user; cd ~/freebsd &prompt.user; svn update --set-depth=immediates . The above command will populate the working copy in ~/freebsd with ROADMAP.txt and empty subdirectories, and nothing will happen when svn update is executed on the subdirectories. However, this command will set the depth for head (in this case) to infinity, and fully populate it: &prompt.user; svn update --set-depth=infinity head Direct Operation Certain operations can be performed directly on the repository without touching the working copy. Specifically, this applies to any operation that does not require editing a file, including: log, diff mkdir remove, copy, rename propset, propedit, propdel merge Branching is very fast. This command would be used to branch RELENG_8: &prompt.user; svn copy svn+ssh://repo.freebsd.org/base/head svn+ssh://repo.freebsd.org/base/stable/8 This is equivalent to these commands which take minutes and hours as opposed to seconds, depending on your network connection: &prompt.user; svn checkout --depth=immediates svn+ssh://repo.freebsd.org/base &prompt.user; cd base &prompt.user; svn update --set-depth=infinity head &prompt.user; svn copy head stable/8 &prompt.user; svn commit stable/8 Merging with <acronym>SVN</acronym> This section deals with merging code from one branch to another (typically, from head to a stable branch). In all examples below, $FSVN refers to the location of the &os; Subversion repository, svn+ssh://repo.freebsd.org/base/. About Merge Tracking From the user's perspective, merge tracking information (or mergeinfo) is stored in a property called svn:mergeinfo, which is a comma-separated list of revisions and ranges of revisions that have been merged. When set on a file, it applies only to that file. When set on a directory, it applies to that directory and its descendants (files and directories) except for those that have their own svn:mergeinfo. It is not inherited. For instance, stable/6/contrib/openpam/ does not implicitly inherit mergeinfo from stable/6/, or stable/6/contrib/. Doing so would make partial checkouts very hard to manage. Instead, mergeinfo is explicitly propagated down the tree. For merging something into branch/foo/bar/, these rules apply: If branch/foo/bar/ does not already have a mergeinfo record, but a direct ancestor (for instance, branch/foo/) does, then that record will be propagated down to branch/foo/bar/ before information about the current merge is recorded. Information about the current merge will not be propagated back up that ancestor. If a direct descendant of branch/foo/bar/ (for instance, branch/foo/bar/baz/) already has a mergeinfo record, information about the current merge will be propagated down to it. If you consider the case where a revision changes several separate parts of the tree (for example, branch/foo/bar/ and branch/foo/quux/), but you only want to merge some of it (for example, branch/foo/bar/), you will see that these rules make sense. If mergeinfo was propagated up, it would seem like that revision had also been merged to branch/foo/quux/, when in fact it had not been. Selecting the Source and Target Branch When Merging Merging to stable/ branches should originate from head/. For example: &prompt.user; svn merge -c r123456 ^/head/ stable/11 &prompt.user; svn commit stable/11 Note the sections below which outline changes to the target location of the stable/ branch starting with stable/10. Merges to releng/ branches should always originate from the corresponding stable/ branch. For example: &prompt.user; svn merge -c r123456 ^/stable/11 releng/11.0 &prompt.user; svn commit releng/11.0 Committers are only permitted to commit to the releng/ branches during a release cycle after receiving approval from the Release Engineering Team, after which only the Security Officer may commit to a releng/ branch for a Security Advisory or Errata Notice. Selecting the Source and Target for <literal>stable/10</literal> and Newer Starting with the stable/10 branch, all merges are merged to and committed from the root of the branch. All merges look like: &prompt.user; svn merge -c r123456 ^/head/ checkout &prompt.user; svn commit checkout Note that checkout must be a complete checkout of the branch to which the merge occurs. Merges to releng/ branches must always originate from the corresponding stable/ branch. For example: &prompt.user; svn merge -c r123456 ^/stable/10 releng/10.0 Selecting the Source and Target for <literal>stable/9</literal> and Older For stable/9 and earlier, a different strategy was used, distributing mergeinfo around the tree so that merges could be performed without a complete checkout. This procedure proved extremely error-prone, with the convenience of partial checkouts for merges significantly outweighed by the complexity of picking mergeinfo targets. The procedure below describes this now-obsoleted process, which should be used only for merges prior to stable/10. Because of mergeinfo propagation, it is important to choose the source and target for the merge carefully to minimise property changes on unrelated directories. The rules for selecting the merge target (the directory where the changes are being merged to) can be summarized: Never merge directly to a file. Never, ever merge directly to a file. Never, ever, ever merge directly to a file. Changes to kernel code are merged to sys/. For instance, a change to the &man.ichwd.4; driver is merged to sys/, not sys/dev/ichwd/. Likewise, a change to the TCP/IP stack is merged to sys/, not sys/netinet/. Changes to code under etc/ is merged at etc/, not below it. Changes to vendor code (code in contrib/, crypto/ and so on) are merged to the directory where vendor imports happen. For instance, a change to crypto/openssl/util/ is merged to crypto/openssl/. This is rarely an issue, however, since changes to vendor code are usually merged wholesale. Changes to userland programs should as a general rule be merged to the directory that contains the Makefile for that program. For instance, a change to usr.bin/xlint/arch/i386/ is merged to usr.bin/xlint/. Changes to userland libraries should as a general rule be merged to the directory that contains the Makefile for that library. For instance, a change to lib/libc/gen/ should be merged to lib/libc/. There may be cases where it makes sense to deviate from the rules for userland programs and libraries. For instance, everything under lib/libpam/ is merged to lib/libpam/, even though the library itself and all of the modules each have their own Makefile. Changes to manual pages are merged to share/man/manN/, for the appropriate value of N. Other changes to share/ are merged to the appropriate subdirectory and not to share/ directly. Changes to a top-level file in the source tree such as UPDATING or Makefile.inc1 are merged directly to that file rather than to the root of the whole tree. Yes, this is an exception to the first three rules. When in doubt, ask. If a merge changes several places at once (for instance, changing a kernel interface and every userland program that uses it), merge each target separately, then commit them together. For instance, if merging a revision that changed a kernel API and updated all the userland bits that used that API, merge the kernel change to sys, and the userland bits to the appropriate userland directories, then commit all of these in one go. The source will almost invariably be the same as the target. For instance, always merge stable/7/lib/libc/ from head/lib/libc/. The only exception would be when merging changes to code that has moved in the source branch but not in the parent branch. For instance, a change to &man.pkill.1; would be merged from bin/pkill/ in head to usr.bin/pkill/ in stable/7. Preparing the Merge Target Because of the mergeinfo propagation issues described earlier, it is very important to never merge changes into a sparse working copy. Always use a full checkout of the branch being merged into. For instance, when merging from HEAD to 7, use a full checkout of stable/7: &prompt.user; cd stable/7 &prompt.user; svn up --set-depth=infinity The target directory must also be up-to-date and must not contain any uncommitted changes or stray files. Identifying Revisions Identifying revisions to be merged is a must. If the target already has complete mergeinfo, ask SVN for a list: &prompt.user; cd stable/6/contrib/openpam &prompt.user; svn mergeinfo --show-revs=eligible $FSVN/head/contrib/openpam If the target does not have complete mergeinfo, check the log for the merge source. Merging Now, let us start merging! The Principles For example, To merge: revision $R in directory $target in stable branch $B from directory $source in head $FSVN is svn+ssh://repo.freebsd.org/base Assuming that revisions $P and $Q have already been merged, and that the current directory is an up-to-date working copy of stable/$B, the existing mergeinfo looks like this: &prompt.user; svn propget svn:mergeinfo -R $target $target - /head/$source:$P,$Q Merging is done like so: &prompt.user; svn merge -c$R $FSVN/head/$source $target Checking the results of this is possible with svn diff. The svn:mergeinfo now looks like: &prompt.user; svn propget svn:mergeinfo -R $target $target - head/$source:$P,$Q,$R If the results are not exactly as shown, assistance may be required before committing as mistakes may have been made, or there may be something wrong with the existing mergeinfo, or there may be a bug in Subversion. Practical Example As a practical example, consider this scenario. The changes to netmap.4 in r238987 are to be merged from CURRENT to 9-STABLE. The file resides in head/share/man/man4. According to , this is also where to do the merge. Note that in this example all paths are relative to the top of the svn repository. For more information on the directory layout, see . The first step is to inspect the existing mergeinfo. &prompt.user; svn propget svn:mergeinfo -R stable/9/share/man/man4 Take a quick note of how it looks before moving on to the next step; doing the actual merge: &prompt.user; svn merge -c r238987 svn+ssh://repo.freebsd.org/base/head/share/man/man4 stable/9/share/man/man4 --- Merging r238987 into 'stable/9/share/man/man4': U stable/9/share/man/man4/netmap.4 --- Recording mergeinfo for merge of r238987 into 'stable/9/share/man/man4': U stable/9/share/man/man4 Check that the revision number of the merged revision has been added. Once this is verified, the only thing left is the actual commit. &prompt.user; svn commit stable/9/share/man/man4 Merging into the Kernel (<filename>sys/</filename>) As stated above, merging into the kernel is different from merging in the rest of the tree. In many ways merging to the kernel is simpler because there is always the same merge target (sys/). Once svn merge has been executed, svn diff has to be run on the directory to check the changes. This may show some unrelated property changes, but these can be ignored. Next, build and test the kernel, and, once the tests are complete, commit the code as normal, making sure that the commit message starts with Merge r226222 from head, or similar. Precautions Before Committing As always, build world (or appropriate parts of it). Check the changes with svn diff and svn stat. Make sure all the files that should have been added or deleted were in fact added or deleted. Take a closer look at any property change (marked by a M in the second column of svn stat). Normally, no svn:mergeinfo properties should be anywhere except the target directory (or directories). If something looks fishy, ask for help. Committing Make sure to commit a top level directory to have the mergeinfo included as well. Do not specify individual files on the command line. For more information about committing files in general, see the relevant section of this primer. Vendor Imports with <acronym>SVN</acronym> Please read this entire section before starting a vendor import. Patches to vendor code fall into two categories: Vendor patches: these are patches that have been issued by the vendor, or that have been extracted from the vendor's version control system, which address issues which cannot wait until the next vendor release. &os; patches: these are patches that modify the vendor code to address &os;-specific issues. The nature of a patch dictates where it should be committed: Vendor patches must be committed to the vendor branch, and merged from there to head. If the patch addresses an issue in a new release that is currently being imported, it must not be committed along with the new release: the release must be imported and tagged first, then the patch can be applied and committed. There is no need to re-tag the vendor sources after committing the patch. &os; patches are committed directly to head. Preparing the Tree If importing for the first time after the switch to Subversion, flattening and cleaning up the vendor tree is necessary, as well as bootstrapping the merge history in the main tree. Flattening During the conversion from CVS to Subversion, vendor branches were imported with the same layout as the main tree. This means that the pf vendor sources ended up in vendor/pf/dist/contrib/pf. The vendor source is best directly in vendor/pf/dist. To flatten the pf tree: &prompt.user; cd vendor/pf/dist/contrib/pf &prompt.user; svn mv $(svn list) ../.. &prompt.user; cd ../.. &prompt.user; svn rm contrib &prompt.user; svn propdel -R svn:mergeinfo . &prompt.user; svn commit The propdel bit is necessary because starting with 1.5, Subversion will automatically add svn:mergeinfo to any directory that is copied or moved. In this case, as nothing is being merged from the deleted tree, they just get in the way. Tags may be flattened as well (3, 4, 3.5 etc.); the procedure is exactly the same, only changing dist to 3.5 or similar, and putting the svn commit off until the end of the process. Cleaning Up The dist tree can be cleaned up as necessary. Disabling keyword expansion is recommended, as it makes no sense on unmodified vendor code and in some cases it can even be harmful. OpenSSH, for example, includes two files that originated with &os; and still contain the original version tags. To do this: &prompt.user; svn propdel svn:keywords -R . &prompt.user; svn commit Bootstrapping Merge History If importing for the first time after the switch to Subversion, bootstrap svn:mergeinfo on the target directory in the main tree to the revision that corresponds to the last related change to the vendor tree, prior to importing new sources: &prompt.user; cd head/contrib/pf &prompt.user; svn merge --record-only svn+ssh://repo.freebsd.org/base/vendor/pf/dist@180876 . &prompt.user; svn commit Importing New Sources With two commits—one for the import itself and one for the tag—this step can optionally be repeated for every upstream release between the last import and the current import. Preparing the Vendor Sources Unlike in CVS where only the needed parts were imported into the vendor tree to avoid bloating the main tree, Subversion is able to store a full distribution in the vendor tree. So, import everything, but merge only what is required. A svn add is required to add any files that were added since the last vendor import, and svn rm is required to remove any that were removed since. Preparing sorted lists of the contents of the vendor tree and of the sources that are about to be imported is recommended, to facilitate the process. &prompt.user; cd vendor/pf/dist &prompt.user; svn list -R | grep -v '/$' | sort >../old &prompt.user; cd ../pf-4.3 &prompt.user; find . -type f | cut -c 3- | sort >../new With these two files, comm -23 ../old ../new will list removed files (files only in old), while comm -13 ../old ../new will list added files only in new. Importing into the Vendor Tree Now, the sources must be copied into dist and the svn add and svn rm commands are used as needed: &prompt.user; cd vendor/pf/pf-4.3 &prompt.user; tar cf - . | tar xf - -C ../dist &prompt.user; cd ../dist &prompt.user; comm -23 ../old ../new | xargs svn rm &prompt.user; comm -13 ../old ../new | xargs svn --parents add If any directories were removed, they will have to be svn rmed manually. Nothing will break if they are not, but they will remain in the tree. Check properties on any new files. All text files should have svn:eol-style set to native. All binary files should have svn:mime-type set to application/octet-stream unless there is a more appropriate media type. Executable files should have svn:executable set to *. No other properties should exist on any file in the tree. Committing is now possible. However, it is good practice to make sure that everything is okay by using the svn stat and svn diff commands. Tagging Once committed, vendor releases are tagged for future reference. The best and quickest way to do this is directly in the repository: &prompt.user; svn cp svn+ssh://repo.freebsd.org/base/vendor/pf/dist svn+ssh://repo.freebsd.org/base/vendor/pf/4.3 Once that is complete, svn up the working copy of vendor/pf to get the new tag, although this is rarely needed. If creating the tag in the working copy of the tree, svn:mergeinfo results must be removed: &prompt.user; cd vendor/pf &prompt.user; svn cp dist 4.3 &prompt.user; svn propdel svn:mergeinfo -R 4.3 Merging to Head &prompt.user; cd head/contrib/pf &prompt.user; svn up &prompt.user; svn merge --accept=postpone svn+ssh://repo.freebsd.org/base/vendor/pf/dist . The --accept=postpone tells Subversion not to complain about merge conflicts as they will be handled manually. The cvs2svn changeover occurred on June 3, 2008. When performing vendor merges for packages which were already present and converted by the cvs2svn process, the command used to merge /vendor/package_name/dist to /head/package_location (for example, head/contrib/sendmail) must use to indicate the revision to merge from the /vendor tree. For example: &prompt.user; svn checkout svn+ssh://repo.freebsd.org/base/head/contrib/sendmail &prompt.user; cd sendmail &prompt.user; svn merge -c r261190 ^/vendor/sendmail/dist . ^ is an alias for the repository path. If using the Zsh shell, the ^ must be escaped with \. This means ^/head should be \^/head. It is necessary to resolve any merge conflicts. Make sure that any files that were added or removed in the vendor tree have been properly added or removed in the main tree. To check diffs against the vendor branch: &prompt.user; svn diff --no-diff-deleted --old=svn+ssh://repo.freebsd.org/base/vendor/pf/dist --new=. The --no-diff-deleted tells Subversion not to complain about files that are in the vendor tree but not in the main tree. Things that would have previously been removed before the vendor import, like the vendor's makefiles and configure scripts. Using CVS, once a file was off the vendor branch, it was not able to be put back. With Subversion, there is no concept of on or off the vendor branch. If a file that previously had local modifications, to make it not show up in diffs in the vendor tree, all that has to be done is remove any left-over cruft like &os; version tags, which is much easier. If any changes are required for the world to build with the new sources, make them now, and keep testing until everything builds and runs perfectly. Committing the Vendor Import Committing is now possible! Everything must be committed in one go. If done properly, the tree will move from a consistent state with old code, to a consistent state with new code. From Scratch Importing into the Vendor Tree This section is an example of importing and tagging byacc into head. First, prepare the directory in vendor: &prompt.user; svn co --depth immediates $FSVN/vendor &prompt.user; cd vendor &prompt.user; svn mkdir byacc &prompt.user; svn mkdir byacc/dist Now, import the sources into the dist directory. Once the files are in place, svn add the new ones, then svn commit and tag the imported version. To save time and bandwidth, direct remote committing and tagging is possible: &prompt.user; svn cp -m "Tag byacc 20120115" $FSVN/vendor/byacc/dist $FSVN/vendor/byacc/20120115 Merging to <literal>head</literal> Due to this being a new file, copy it for the merge: &prompt.user; svn cp -m "Import byacc to contrib" $FSVN/vendor/byacc/dist $FSVN/head/contrib/byacc Working normally on newly imported sources is still possible. Reverting a Commit Reverting a commit to a previous version is fairly easy: &prompt.user; svn merge -r179454:179453 ROADMAP.txt &prompt.user; svn commit Change number syntax, with negative meaning a reverse change, can also be used: &prompt.user; svn merge -c -179454 ROADMAP.txt &prompt.user; svn commit This can also be done directly in the repository: &prompt.user; svn merge -r179454:179453 svn+ssh://repo.freebsd.org/base/ROADMAP.txt It is important to ensure that the mergeinfo is correct when reverting a file to permit svn mergeinfo --eligible to work as expected. Reverting the deletion of a file is slightly different. Copying the version of the file that predates the deletion is required. For example, to restore a file that was deleted in revision N, restore version N-1: &prompt.user; svn copy svn+ssh://repo.freebsd.org/base/ROADMAP.txt@179454 &prompt.user; svn commit or, equally: &prompt.user; svn copy svn+ssh://repo.freebsd.org/base/ROADMAP.txt@179454 svn+ssh://repo.freebsd.org/base Do not simply recreate the file manually and svn add it—this will cause history to be lost. Fixing Mistakes While we can do surgery in an emergency, do not plan on having mistakes fixed behind the scenes. Plan on mistakes remaining in the logs forever. Be sure to check the output of svn status and svn diff before committing. Mistakes will happen but, they can generally be fixed without disruption. Take a case of adding a file in the wrong location. The right thing to do is to svn move the file to the correct location and commit. This causes just a couple of lines of metadata in the repository journal, and the logs are all linked up correctly. The wrong thing to do is to delete the file and then svn add an independent copy in the correct location. Instead of a couple of lines of text, the repository journal grows an entire new copy of the file. This is a waste. Setting up a <application>svnsync</application> Mirror Avoid setting up a svnsync mirror unless there is a very good reason for it. Such reasons might be to support multiple local read-only client machines, or if the network bandwidth is limited. Starting a fresh mirror from empty would take a very long time. Expect a minimum of 10 hours for high speed connectivity. If international links are involved, expect this to take four to ten times longer. A far better option is to grab a seed file. It is large (~1GB) but will consume less network traffic and take less time to fetch than a svnsync will. There are several ways to do this: &prompt.user; rsync -va --partial --progress freefall:/home/peter/svnmirror-base-r179637.tbz2 . &prompt.user; rsync -va --partial --progress rsync://repoman.freebsd.org:50873/svnseed/svnmirror-base-r215629.tar.xz . &prompt.user; fetch ftp://ftp.freebsd.org/pub/FreeBSD/development/subversion/svnmirror-base-r221445.tar.xz Extract the file to somewhere like home/svnmirror/base/. Then, update it, so that it fetches changes since the last revision in the archive: &prompt.user; svnsync sync file:///home/svnmirror/base Now, set that up to run from &man.cron.8;, do checkouts locally, set up a svnserve server for local machines to talk to, etc. The seed mirror is set to fetch from svn://svn.freebsd.org/base. The configuration for the mirror is stored in revprop 0 on the local mirror. To see the configuration, try: &prompt.user; svn proplist -v --revprop -r 0 file:///home/svnmirror/base Use propset to change things. Committing High-<acronym>ASCII</acronym> Data Files that have high-ASCII bits are considered binary files in SVN, so the pre-commit checks fail and indicate that the mime-type property should be set to application/octet-stream. However, the use of this is discouraged, so please do not set it. The best way is always avoiding high-ASCII data, so that it can be read everywhere with any text editor but if it is not avoidable, instead of changing the mime-type, set the fbsd:notbinary property with propset: &prompt.user; svn propset fbsd:notbinary yes foo.data Maintaining a Project Branch A project branch is one that is synced to head (or another branch) is used to develop a project then commit it back to head. In SVN, dolphin branching is used for this. A dolphin branch is one that diverges for a while and is finally committed back to the original branch. During development code migration in one direction (from head to the branch only). No code is committed back to head until the end. After the branch is committed back at the end, it is dead (although a new branch with the same name can be created after the dead one is deleted). As per https://people.FreeBSD.org/~peter/svn_notes.txt, work that is intended to be merged back into HEAD should be in base/projects/. If the work is beneficial to the &os; community in some way but not intended to be merged directly back into HEAD then the proper location is base/user/username/. This page contains further details. To create a project branch: &prompt.user; svn copy svn+ssh://repo.freebsd.org/base/head svn+ssh://repo.freebsd.org/base/projects/spif To merge changes from HEAD back into the project branch: &prompt.user; cd copy_of_spif &prompt.user; svn merge svn+ssh://repo.freebsd.org/base/head &prompt.user; svn commit It is important to resolve any merge conflicts before committing. Some Tips In commit logs etc., rev 179872 is spelled r179872 as per convention. Speeding up svn is possible by adding these entries to ~/.ssh/config: Host * ControlPath ~/.ssh/sockets/master-%l-%r@%h:%p ControlMaster auto ControlPersist yes and then typing mkdir ~/.ssh/sockets Checking out a working copy with a stock Subversion client without &os;-specific patches (OPTIONS_SET=FREEBSD_TEMPLATE) will mean that $FreeBSD$ tags will not be expanded. Once the correct version has been installed, trick Subversion into expanding them like so: &prompt.user; svn propdel -R svn:keywords . &prompt.user; svn revert -R . This will wipe out uncommitted patches. It is possible to automatically fill the "Sponsored by" and "MFC after" commit log fields by setting "freebsd-sponsored-by" and "freebsd-mfc-after" fields in the "[miscellany]" section of the ~/.subversion/config configuration file. For example: freebsd-sponsored-by = The FreeBSD Foundation freebsd-mfc-after = 2 weeks Setup, Conventions, and Traditions There are a number of things to do as a new developer. The first set of steps is specific to committers only. These steps must be done by a mentor for those who are not committers. For New Committers Those who have been given commit rights to the &os; repositories must follow these steps. Get mentor approval before committing each of these changes! The .ent and .xml files mentioned below exist in the &os; Documentation Project SVN repository at svn+ssh://repo.FreeBSD.org/doc/. New files that do not have the FreeBSD=%H svn:keywords property will be rejected when attempting to commit them to the repository. Be sure to read regarding adding and removing files. Verify that ~/.subversion/config contains the necessary auto-props entries from auto-props.txt mentioned there. All src commits go to &os.current; first before being merged to &os.stable;. The &os.stable; branch must maintain ABI and API compatibility with earlier versions of that branch. Do not merge changes that break this compatibility. Steps for New Committers Add an Author Entity doc/head/share/xml/authors.ent — Add an author entity. Later steps depend on this entity, and missing this step will cause the doc/ build to fail. This is a relatively easy task, but remains a good first test of version control skills. Update the List of Developers and Contributors doc/head/en_US.ISO8859-1/articles/contributors/contrib.committers.xml — Add an entry to the Developers section of the Contributors List. Entries are sorted by last name. doc/head/en_US.ISO8859-1/articles/contributors/contrib.additional.xmlRemove the entry from the Additional Contributors section. Entries are sorted by first name. Add a News Item doc/head/share/xml/news.xml — Add an entry. Look for the other entries that announce new committers and follow the format. Use the date from the commit bit approval email from core@FreeBSD.org. Add a <acronym>PGP</acronym> Key doc/head/share/pgpkeys/pgpkeys.ent and doc/head/share/pgpkeys/pgpkeys-developers.xml - Add your PGP or GnuPG key. Those who do not yet have a key should see . &a.des.email; has written a shell script (doc/head/share/pgpkeys/addkey.sh) to make this easier. See the README file for more information. Use doc/head/share/pgpkeys/checkkey.sh to verify that keys meet minimal best-practices standards. After adding and checking a key, add both updated files to source control and then commit them. Entries in this file are sorted by last name. It is very important to have a current PGP/GnuPG key in the repository. The key may be required for positive identification of a committer. For example, the &a.admins; might need it for account recovery. A complete keyring of FreeBSD.org users is available for download from https://www.FreeBSD.org/doc/pgpkeyring.txt. Update Mentor and Mentee Information base/head/share/misc/committers-repository.dot — Add an entry to the current committers section, where repository is doc, ports, or src, depending on the commit privileges granted. Add an entry for each additional mentor/mentee relationship in the bottom section. Generate a <application>Kerberos</application> Password See to generate or set a Kerberos for use with other &os; services like the bug tracking database. Optional: Enable Wiki Account &os; Wiki Account — A wiki account allows sharing projects and ideas. Those who do not yet have an account can follow instructions on the AboutWiki Page to obtain one. Contact clusteradm@FreeBSD.org if you need help with your Wiki account. Optional: Update Wiki Information Wiki Information - After gaining access to the wiki, some people add entries to the How We Got Here, Irc Nicks, and Dogs of FreeBSD pages. Optional: Update Ports with Personal Information ports/astro/xearth/files/freebsd.committers.markers and src/usr.bin/calendar/calendars/calendar.freebsd - Some people add entries for themselves to these files to show where they are located or the date of their birthday. Optional: Prevent Duplicate Mailings Subscribers to &a.svn-src-all.name;, &a.svn-ports-all.name; or &a.svn-doc-all.name; might wish to unsubscribe to avoid receiving duplicate copies of commit messages and followups. For Everyone Introduce yourself to the other developers, otherwise no one will have any idea who you are or what you are working on. The introduction need not be a comprehensive biography, just write a paragraph or two about who you are, what you plan to be working on as a developer in &os;, and who will be your mentor. Email this to the &a.developers; and you will be on your way! Log into freefall.FreeBSD.org and create a /var/forward/user (where user is your username) file containing the e-mail address where you want mail addressed to yourusername@FreeBSD.org to be forwarded. This includes all of the commit messages as well as any other mail addressed to the &a.committers; and the &a.developers;. Really large mailboxes which have taken up permanent residence on freefall may get truncated without warning if space needs to be freed, so forward it or save it elsewhere. Due to the severe load dealing with SPAM places on the central mail servers that do the mailing list processing, the front-end server does do some basic checks and will drop some messages based on these checks. At the moment proper DNS information for the connecting host is the only check in place but that may change. Some people blame these checks for bouncing valid email. To have these checks turned off for your email, create a file named ~/.spam_lover on freefall.FreeBSD.org. Those who are developers but not committers will not be subscribed to the committers or developers mailing lists. The subscriptions are derived from the access rights. Mentors All new developers have a mentor assigned to them for the first few months. A mentor is responsible for teaching the mentee the rules and conventions of the project and guiding their first steps in the developer community. The mentor is also personally responsible for the mentee's actions during this initial period. For committers: do not commit anything without first getting mentor approval. Document that approval with an Approved by: line in the commit message. When the mentor decides that a mentee has learned the ropes and is ready to commit on their own, the mentor announces it with a commit to conf/mentors. This file is in the svnadmin branch of each repository: src base/svnadmin/conf/mentors doc doc/svnadmin/conf/mentors ports ports/svnadmin/conf/mentors Commit Log Messages This section contains some suggestions and traditions for how commit logs are formatted. As well as including an informative message with each commit, some additional information may be needed. This information consists of one or more lines containing the key word or phrase, a colon, tabs for formatting, and then the additional information. The key words or phrases are: PR: The problem report (if any) which is affected (typically, by being closed) by this commit. Multiple PRs may be specified on one line, separated by commas or spaces. Submitted by: The name and e-mail address of the person that submitted the fix; for developers, just the username on the &os; cluster. If the submitter is the maintainer of the port being committed, include "(maintainer)" after the email address. Avoid obfuscating the email address of the submitter as this adds additional work when searching logs. Reviewed by: The name and e-mail address of the person or people that reviewed the change; for developers, just the username on the &os; cluster. If a patch was submitted to a mailing list for review, and the review was favorable, then just include the list name. Approved by: The name and e-mail address of the person or people that approved the change; for developers, just the username on the &os; cluster. It is customary to get prior approval for a commit if it is to an area of the tree to which you do not usually commit. In addition, during the run up to a new release all commits must be approved by the release engineering team. While under mentorship, get mentor approval before the commit. Enter the mentor's username in this field, and note that they are a mentor: Approved by: username-of-mentor (mentor) If a team approved these commits then include the team name followed by the username of the approver in parentheses. For example: Approved by: re (username) Obtained from: The name of the project (if any) from which the code was obtained. Do not use this line for the name of an individual person. MFC after: If you wish to receive an e-mail reminder to MFC at a later date, specify the number of days, weeks, or months after which an MFC is planned. MFC to: If the commit should be merged to a subset of stable branches, specify the branch names. MFC with: If the commit should be merged together with a previous one in a single MFC commit (for example, where this commit corrects a bug in the previous change), specify the corresponding revision number. Relnotes: If the change is a candidate for inclusion in the release notes for the next release from the branch, set to yes. Security: If the change is related to a security vulnerability or security exposure, include one or more references or a description of the issue. If possible, include a VuXML URL or a CVE ID. Differential Revision: The full URL of the Phabricator review. This line must be the last line. For example: https://reviews.freebsd.org/D1708. Commit Log for a Commit Based on a PR The commit is based on a patch from a PR submitted by John Smith. The commit message PR and Submitted by fields are filled.. ...

MFC after: 2 weeks Where 2 is the number of days, weeks, or months after which an MFC is planned. The weeks option may be day, days, week, weeks, month, months. It is often necessary to combine these. Consider the situation where a user has submitted a PR containing code from the NetBSD project. Looking at the PR, the developer sees it is not an area of the tree they normally work in, so they have the change reviewed by the arch mailing list. Since the change is complex, the developer opts to MFC after one month to allow adequate testing. The extra information to include in the commit would look something like Example Combined Commit Log PR: 54321 Submitted by: John Smith <John.Smith@example.com> Reviewed by: -arch Obtained from: NetBSD MFC after: 1 month Relnotes: yes Preferred License for New Files The &os; Project suggests and uses this text as the preferred license scheme: /*- * SPDX-License-Identifier: BSD-2-Clause-FreeBSD * * Copyright (c) [year] [your name] * * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions * are met: * 1.

Due to the large number of contributors to the &os; project, complying with this clause for many commercial vendors has become difficult. If you have code in the tree with the advertising clause, please consider removing it. In fact, please consider using the above license for your code. The &os; project discourages completely new licenses and variations on the standard licenses. New licenses require the approval of the &a.core; to reside in the main repository. The more different licenses that are used in the tree, the more problems that this causes to those wishing to utilize this code, typically from unintended consequences from a poorly worded license. Project policy dictates that code under some non-BSD licenses must be placed only in specific sections of the repository, and in some cases, compilation must be conditional or even disabled by default. For example, the GENERIC kernel must be compiled under only licenses identical to or substantially similar to the BSD license. GPL, APSL, CDDL, etc, licensed software must not be compiled into GENERIC. Developers are reminded that in open source, getting "open" right is just as important as getting "source" right, as improper handling of intellectual property has serious consequences. Any questions or concerns should immediately be brought to the attention of the core team. Keeping Track of Licenses Granted to the &os; Project Various software or data exist in the repositories where the &os; project has been granted a special licence to be able to use them. A case in point are the Terminus fonts for use with &man.vt.4;. Here the author Dimitar Zhekov has allowed us to use the "Terminus BSD Console" font under a 2-clause BSD license rather than the regular Open Font License he normally uses. It is clearly sensible to keep a record of any such license grants. To that end, the &a.core; has decided to keep an archive of them. Whenever the &os; project is granted a special license we require the &a.core; to be notified. Any developers involved in arranging such a license grant, please send details to the &a.core; including: Contact details for people or organizations granting the special license. What files, directories etc. in the repositories are covered by the license grant including the revision numbers where any specially licensed material was committed. The date the license comes into effect from. Unless otherwise agreed, this will be the date the license was issued by the authors of the software in question. The license text. A note of any restrictions, limitations or exceptions that apply specifically to &os;'s usage of the licensed material. Any other relevant information. Once the &a.core; is satisfied that all the necessary details have been gathered and are correct, the secretary will send a PGP-signed acknowledgement of receipt including the license details. This receipt will be persistently archived and serve as our permanent record of the license grant. The license archive should contain only details of license grants; this is not the place for any discussions around licensing or other subjects. Access to data within the license archive will be available on request to the &a.core;. Developer Relations When working directly on your own code or on code which is already well established as your responsibility, then there is probably little need to check with other committers before jumping in with a commit. Working on a bug in an area of the system which is clearly orphaned (and there are a few such areas, to our shame), the same applies. Trying to modify something which is clearly being actively maintained by someone else (and it is only by watching the repository-committers mailing list that a developer can really get a feel for just what is and is not) then consider sending the change to them instead, just as a developer would have before becoming a committer. For ports, contact the listed MAINTAINER in the Makefile. For other parts of the repository, if it is not clear who the active maintainer is, it may help to scan the revision history to see who has committed changes in the past. An example script that lists each person who has committed to a given file along with the number of commits each person has made can be found at on freefall at ~eadler/bin/whodid. If queries go unanswered or the committer otherwise indicates a lack of interest in the area affected, go ahead and commit it. Avoid sending private emails to maintainers. Other people might be interested in the conversation, not just the final output. If there is any doubt about a commit for any reason at all, have it reviewed by -hackers before committing. Better to have it flamed then and there rather than when it is part of the repository. If a commit does results in controversy erupting, it may be advisable to consider backing the change out again until the matter is settled. Remember, with a version control system we can always change it back. Do not impugn the intentions of others. If they see a different solution to a problem, or even a different problem, it is probably not because they are stupid, because they have questionable parentage, or because they are trying to destroy hard work, personal image, or &os;, but basically because they have a different outlook on the world. Different is good. Disagree honestly. Argue your position from its merits, be honest about any shortcomings it may have, and be open to seeing their solution, or even their vision of the problem, with an open mind. Accept correction. We are all fallible. When you have made a mistake, apologize and get on with life. Do not beat up yourself, and certainly do not beat up others for your mistake. Do not waste time on embarrassment or recrimination, just fix the problem and move on. Ask for help. Seek out (and give) peer reviews. One of the ways open source software is supposed to excel is in the number of eyeballs applied to it; this does not apply if nobody will review code. If in Doubt... When unsure about something, whether it be a technical issue or a project convention be sure to ask. If you stay silent you will never make progress. If it relates to a technical issue ask on the public mailing lists. Avoid the temptation to email the individual person that knows the answer. This way everyone will be able to learn from the question and the answer. For project specific or administrative questions ask, in order: Your mentor or former mentor. An experienced committer on IRC, email, etc. Any team with a "hat", as they can give you a definitive answer. If still not sure, ask on &a.developers;. Once your question is answered, if no one pointed you to documentation that spelled out the answer to your question, document it, as others will have the same question. Bugzilla The &os; Project utilizes Bugzilla for tracking bugs and change requests. Be sure that if you commit a fix or suggestion found in the PR database to close it. It is also considered nice if you take time to close any PRs associated with your commits, if appropriate. Committers with non-&os;.org Bugzilla accounts can have the old account merged with the &os;.org account by following these steps: Log in using your old account. Open new bug. Choose Services as the Product, and Bug Tracker as the Component. In bug description list acounts you wish to be merged. Log in using &os;.org account and post comment to newly opened bug to confirm ownership. See for more details on how to generate or set a password for your &os;.org account. If there are more than two accounts to merge, post comments from each of them. You can find out more about Bugzilla at: &os; Problem Report Handling Guidelines https://www.FreeBSD.org/support.html Phabricator The &os; Project utilizes Phabricator for code review requests. See the CodeReview wiki page for details. Committers with non-&os;.org Phabricator accounts can have the old account renamed to the &os;.org account by following these steps: Change your Phabricator account email to your &os;.org email. Open new bug on our bug tracker using your &os;.org account, see for more information. Choose Services as the Product, and Code Review as the Component. In bug description request that your Phabricator account be renamed, and provide a link to your Phabricator user. For example, https://reviews.freebsd.org/p/bob_example.com/ Phabricator accounts cannot be merged, please do not open a new account. Who's Who Besides the repository meisters, there are other &os; project members and teams whom you will probably get to know in your role as a committer. Briefly, and by no means all-inclusively, these are: &a.doceng; doceng is the group responsible for the documentation build infrastructure, approving new documentation committers, and ensuring that the &os; website and documentation on the FTP site is up to date with respect to the subversion tree. It is not a conflict resolution body. The vast majority of documentation related discussion takes place on the &a.doc;. More details regarding the doceng team can be found in its charter. Committers interested in contributing to the documentation should familiarize themselves with the Documentation Project Primer. &a.bde.email; Bruce is the Style Police-Meister. When you do a commit that could have been done better, Bruce will be there to tell you. Be thankful that someone is. Bruce is also very knowledgeable on the various standards applicable to &os;. &a.re.members.email; These are the members of the &a.re;. This team is responsible for setting release deadlines and controlling the release process. During code freezes, the release engineers have final authority on all changes to the system for whichever branch is pending release status. If there is something you want merged from &os.current; to &os.stable; (whatever values those may have at any given time), these are the people to talk to about it. Hiroki is also the keeper of the release documentation (src/release/doc/*). If you commit a change that you think is worthy of mention in the release notes, please make sure he knows about it. Better still, send him a patch with your suggested commentary. &a.so.email; &a.so; is the &os; Security Officer and oversees the &a.security-officer;. &a.wollman.email; If you need advice on obscure network internals or are not sure of some potential change to the networking subsystem you have in mind, Garrett is someone to talk to. Garrett is also very knowledgeable on the various standards applicable to &os;. &a.committers; &a.svn-src-all.name;, &a.svn-ports-all.name; and &a.svn-doc-all.name; are the mailing lists that the version control system uses to send commit messages to. Never send email directly to these lists. Only send replies to this list when they are short and are directly related to a commit. &a.developers; All committers are subscribed to -developers. This list was created to be a forum for the committers community issues. Examples are Core voting, announcements, etc. The &a.developers; is for the exclusive use of &os; committers. To develop &os;, committers must have the ability to openly discuss matters that will be resolved before they are publicly announced. Frank discussions of work in progress are not suitable for open publication and may harm &os;. All &os; committers are expected not to not publish or forward messages from the &a.developers; outside the list membership without permission of all of the authors. Violators will be removed from the &a.developers;, resulting in a suspension of commit privileges. Repeated or flagrant violations may result in permanent revocation of commit privileges. This list is not intended as a place for code reviews or for any technical discussion. In fact using it as such hurts the &os; Project as it gives a sense of a closed list where general decisions affecting all of the &os; using community are made without being open. Last, but not least never, never ever, email the &a.developers; and CC:/BCC: another &os; list. Never, ever email another &os; email list and CC:/BCC: the &a.developers;. Doing so can greatly diminish the benefits of this list. SSH Quick-Start Guide If you do not wish to type your password in every time you use &man.ssh.1;, and you use keys to authenticate, &man.ssh-agent.1; is there for your convenience. If you want to use &man.ssh-agent.1;, make sure that you run it before running other applications. X users, for example, usually do this from their .xsession or .xinitrc. See &man.ssh-agent.1; for details. Generate a key pair using &man.ssh-keygen.1;. The key pair will wind up in your $HOME/.ssh/ directory. Only ECDSA, Ed25519 or RSA keys are supported. Send your public key ($HOME/.ssh/id_ecdsa.pub, $HOME/.ssh/id_ed25519.pub, or $HOME/.ssh/id_rsa.pub) to the person setting you up as a committer so it can be put into yourlogin in /etc/ssh-keys/ on freefall. Now &man.ssh-add.1; can be used for authentication once per session. It prompts for the private key's pass phrase, and then stores it in the authentication agent (&man.ssh-agent.1;). Use ssh-add -d to remove keys stored in the agent. Test with a simple remote command: ssh freefall.FreeBSD.org ls /usr. For more information, see security/openssh, &man.ssh.1;, &man.ssh-add.1;, &man.ssh-agent.1;, &man.ssh-keygen.1;, and &man.scp.1;. For information on adding, changing, or removing &man.ssh.1; keys, see this article. &coverity; Availability for &os; Committers All &os; developers can obtain access to Coverity analysis results of all &os; Project software. All who are interested in obtaining access to the analysis results of the automated Coverity runs, can sign up at Coverity Scan. The &os; wiki includes a mini-guide for developers who are interested in working with the &coverity; analysis reports: https://wiki.freebsd.org/CoverityPrevent. Please note that this mini-guide is only readable by &os; developers, so if you cannot access this page, you will have to ask someone to add you to the appropriate Wiki access list. Finally, all &os; developers who are going to use &coverity; are always encouraged to ask for more details and usage information, by posting any questions to the mailing list of the &os; developers. The &os; Committers' Big List of Rules Everyone involved with the &os; project is expected to abide by the Code of Conduct available from https://www.FreeBSD.org/internal/code-of-conduct.html. As committers, you form the public face of the project, and how you behave has a vital impact on the public perception of it. This guide expands on the parts of the Code of Conduct specific to committers. Respect other committers. Respect other contributors. Discuss any significant change before committing. Respect existing maintainers (if listed in the MAINTAINER field in Makefile or in MAINTAINER in the top-level directory). Any disputed change must be backed out pending resolution of the dispute if requested by a maintainer. Security related changes may override a maintainer's wishes at the Security Officer's discretion. Changes go to &os.current; before &os.stable; unless specifically permitted by the release engineer or unless they are not applicable to &os.current;. Any non-trivial or non-urgent change which is applicable should also be allowed to sit in &os.current; for at least 3 days before merging so that it can be given sufficient testing. The release engineer has the same authority over the &os.stable; branch as outlined for the maintainer in rule #5. Do not fight in public with other committers; it looks bad. Respect all code freezes and read the committers and developers mailing lists in a timely manner so you know when a code freeze is in effect. When in doubt on any procedure, ask first! Test your changes before committing them. Do not commit to anything under the src/contrib, src/crypto, or src/sys/contrib trees without explicit approval from the respective maintainers. As noted, breaking some of these rules can be grounds for suspension or, upon repeated offense, permanent removal of commit privileges. Individual members of core have the power to temporarily suspend commit privileges until core as a whole has the chance to review the issue. In case of an emergency (a committer doing damage to the repository), a temporary suspension may also be done by the repository meisters. Only a 2/3 majority of core has the authority to suspend commit privileges for longer than a week or to remove them permanently. This rule does not exist to set core up as a bunch of cruel dictators who can dispose of committers as casually as empty soda cans, but to give the project a kind of safety fuse. If someone is out of control, it is important to be able to deal with this immediately rather than be paralyzed by debate. In all cases, a committer whose privileges are suspended or revoked is entitled to a hearing by core, the total duration of the suspension being determined at that time. A committer whose privileges are suspended may also request a review of the decision after 30 days and every 30 days thereafter (unless the total suspension period is less than 30 days). A committer whose privileges have been revoked entirely may request a review after a period of 6 months has elapsed. This review policy is strictly informal and, in all cases, core reserves the right to either act on or disregard requests for review if they feel their original decision to be the right one. In all other aspects of project operation, core is a subset of committers and is bound by the same rules. Just because someone is in core this does not mean that they have special dispensation to step outside any of the lines painted here; core's special powers only kick in when it acts as a group, not on an individual basis. As individuals, the core team members are all committers first and core second. Details Respect other committers. This means that you need to treat other committers as the peer-group developers that they are. Despite our occasional attempts to prove the contrary, one does not get to be a committer by being stupid and nothing rankles more than being treated that way by one of your peers. Whether we always feel respect for one another or not (and everyone has off days), we still have to treat other committers with respect at all times, on public forums and in private email. Being able to work together long term is this project's greatest asset, one far more important than any set of changes to the code, and turning arguments about code into issues that affect our long-term ability to work harmoniously together is just not worth the trade-off by any conceivable stretch of the imagination. To comply with this rule, do not send email when you are angry or otherwise behave in a manner which is likely to strike others as needlessly confrontational. First calm down, then think about how to communicate in the most effective fashion for convincing the other persons that your side of the argument is correct, do not just blow off some steam so you can feel better in the short term at the cost of a long-term flame war. Not only is this very bad energy economics, but repeated displays of public aggression which impair our ability to work well together will be dealt with severely by the project leadership and may result in suspension or termination of your commit privileges. The project leadership will take into account both public and private communications brought before it. It will not seek the disclosure of private communications, but it will take it into account if it is volunteered by the committers involved in the complaint. All of this is never an option which the project's leadership enjoys in the slightest, but unity comes first. No amount of code or good advice is worth trading that away. Respect other contributors. You were not always a committer. At one time you were a contributor. Remember that at all times. Remember what it was like trying to get help and attention. Do not forget that your work as a contributor was very important to you. Remember what it was like. Do not discourage, belittle, or demean contributors. Treat them with respect. They are our committers in waiting. They are every bit as important to the project as committers. Their contributions are as valid and as important as your own. After all, you made many contributions before you became a committer. Always remember that. Consider the points raised under and apply them also to contributors. Discuss any significant change before committing. The repository is not where changes are initially submitted for correctness or argued over, that happens first in the mailing lists or by use of the Phabricator service. The commit will only happen once something resembling consensus has been reached. This does not mean that permission is required before correcting every obvious syntax error or manual page misspelling, just that it is good to develop a feel for when a proposed change is not quite such a no-brainer and requires some feedback first. People really do not mind sweeping changes if the result is something clearly better than what they had before, they just do not like being surprised by those changes. The very best way of making sure that things are on the right track is to have code reviewed by one or more other committers. When in doubt, ask for review! Respect existing maintainers if listed. Many parts of &os; are not owned in the sense that any specific individual will jump up and yell if you commit a change to their area, but it still pays to check first. One convention we use is to put a maintainer line in the Makefile for any package or subtree which is being actively maintained by one or more people; see https://www.FreeBSD.org/doc/en_US.ISO8859-1/books/developers-handbook/policies.html for documentation on this. Where sections of code have several maintainers, commits to affected areas by one maintainer need to be reviewed by at least one other maintainer. In cases where the maintainer-ship of something is not clear, look at the repository logs for the files in question and see if someone has been working recently or predominantly in that area. Other areas of &os; fall under the control of someone who manages an overall category of &os; evolution, such as internationalization or networking. See https://www.FreeBSD.org/administration.html for more information on this. Any disputed change must be backed out pending resolution of the dispute if requested by a maintainer. Security related changes may override a maintainer's wishes at the Security Officer's discretion. This may be hard to swallow in times of conflict (when each side is convinced that they are in the right, of course) but a version control system makes it unnecessary to have an ongoing dispute raging when it is far easier to simply reverse the disputed change, get everyone calmed down again and then try to figure out what is the best way to proceed. If the change turns out to be the best thing after all, it can be easily brought back. If it turns out not to be, then the users did not have to live with the bogus change in the tree while everyone was busily debating its merits. People very rarely call for back-outs in the repository since discussion generally exposes bad or controversial changes before the commit even happens, but on such rare occasions the back-out should be done without argument so that we can get immediately on to the topic of figuring out whether it was bogus or not. Changes go to &os.current; before &os.stable; unless specifically permitted by the release engineer or unless they are not applicable to &os.current;. Any non-trivial or non-urgent change which is applicable should also be allowed to sit in &os.current; for at least 3 days before merging so that it can be given sufficient testing. The release engineer has the same authority over the &os.stable; branch as outlined in rule #5. This is another do not argue about it issue since it is the release engineer who is ultimately responsible (and gets beaten up) if a change turns out to be bad. Please respect this and give the release engineer your full cooperation when it comes to the &os.stable; branch. The management of &os.stable; may frequently seem to be overly conservative to the casual observer, but also bear in mind the fact that conservatism is supposed to be the hallmark of &os.stable; and different rules apply there than in &os.current;. There is also really no point in having &os.current; be a testing ground if changes are merged over to &os.stable; immediately. Changes need a chance to be tested by the &os.current; developers, so allow some time to elapse before merging unless the &os.stable; fix is critical, time sensitive or so obvious as to make further testing unnecessary (spelling fixes to manual pages, obvious bug/typo fixes, etc.) In other words, apply common sense. Changes to the security branches (for example, releng/9.3) must be approved by a member of the &a.security-officer;, or in some cases, by a member of the &a.re;. Do not fight in public with other committers; it looks bad. This project has a public image to uphold and that image is very important to all of us, especially if we are to continue to attract new members. There will be occasions when, despite everyone's very best attempts at self-control, tempers are lost and angry words are exchanged. The best thing that can be done in such cases is to minimize the effects of this until everyone has cooled back down. Do not air angry words in public and do not forward private correspondence or other private communications to public mailing lists, mail aliases, instant messaging channels or social media sites. What people say one-to-one is often much less sugar-coated than what they would say in public, and such communications therefore have no place there - they only serve to inflame an already bad situation. If the person sending a flame-o-gram at least had the grace to send it privately, then have the grace to keep it private yourself. If you feel you are being unfairly treated by another developer, and it is causing you anguish, bring the matter up with core rather than taking it public. Core will do its best to play peace makers and get things back to sanity. In cases where the dispute involves a change to the codebase and the participants do not appear to be reaching an amicable agreement, core may appoint a mutually-agreeable third party to resolve the dispute. All parties involved must then agree to be bound by the decision reached by this third party. Respect all code freezes and read the committers and developers mailing list on a timely basis so you know when a code freeze is in effect. Committing unapproved changes during a code freeze is a really big mistake and committers are expected to keep up-to-date on what is going on before jumping in after a long absence and committing 10 megabytes worth of accumulated stuff. People who abuse this on a regular basis will have their commit privileges suspended until they get back from the &os; Happy Reeducation Camp we run in Greenland. When in doubt on any procedure, ask first! Many mistakes are made because someone is in a hurry and just assumes they know the right way of doing something. If you have not done it before, chances are good that you do not actually know the way we do things and really need to ask first or you are going to completely embarrass yourself in public. There is no shame in asking how in the heck do I do this? We already know you are an intelligent person; otherwise, you would not be a committer. Test your changes before committing them. This may sound obvious, but if it really were so obvious then we probably would not see so many cases of people clearly not doing this. If your changes are to the kernel, make sure you can still compile both GENERIC and LINT. If your changes are anywhere else, make sure you can still make world. If your changes are to a branch, make sure your testing occurs with a machine which is running that code. If you have a change which also may break another architecture, be sure and test on all supported architectures. Please refer to the &os; Internal Page for a list of available resources. As other architectures are added to the &os; supported platforms list, the appropriate shared testing resources will be made available. Do not commit to anything under the src/contrib, src/crypto, and src/sys/contrib trees without explicit approval from the respective maintainers. The trees mentioned above are for contributed software usually imported onto a vendor branch. Committing something there, even if it does not take the file off the vendor branch, may cause unnecessary headaches for those responsible for maintaining that particular piece of software. Thus, unless you have explicit approval from the maintainer (or you are the maintainer), do not commit there! Please note that this does not mean you should not try to improve the software in question; you are still more than welcome to do so. Ideally, submit your patches to the vendor. If your changes are &os;-specific, talk to the maintainer; they may be willing to apply them locally. But whatever you do, do not commit there by yourself! Contact the &a.core; if you wish to take up maintainership of an unmaintained part of the tree. Policy on Multiple Architectures &os; has added several new architecture ports during recent release cycles and is truly no longer an &i386; centric operating system. In an effort to make it easier to keep &os; portable across the platforms we support, core has developed this mandate:
Our 32-bit reference platform is &arch.i386;, and our 64-bit reference platform is &arch.amd64;. Major design work (including major API and ABI changes) must prove itself on at least one 32-bit and at least one 64-bit platform, preferably the primary reference platforms, before it may be committed to the source tree.
The &arch.i386; and &arch.amd64; platforms were chosen due to being more readily available to developers and as representatives of more diverse processor and system designs - big versus little endian, register file versus register stack, different DMA and cache implementations, hardware page tables versus software TLB management etc. We will continue to re-evaluate this policy as cost and availability of the 64-bit platforms change. Developers should also be aware of our Tier Policy for the long term support of hardware architectures. The rules here are intended to provide guidance during the development process, and are distinct from the requirements for features and architectures listed in that section. The Tier rules for feature support on architectures at release-time are more strict than the rules for changes during the development process.
Other Suggestions When committing documentation changes, use a spell checker before committing. For all XML docs, verify that the formatting directives are correct by running make lint and textproc/igor. For manual pages, run sysutils/manck and textproc/igor over the manual page to verify all of the cross references and file references are correct and that the man page has all of the appropriate MLINKs installed. Do not mix style fixes with new functionality. A style fix is any change which does not modify the functionality of the code. Mixing the changes obfuscates the functionality change when asking for differences between revisions, which can hide any new bugs. Do not include whitespace changes with content changes in commits to doc/ . The extra clutter in the diffs makes the translators' job much more difficult. Instead, make any style or whitespace changes in separate commits that are clearly labeled as such in the commit message. Deprecating Features When it is necessary to remove functionality from software in the base system, follow these guidelines whenever possible: Mention is made in the manual page and possibly the release notes that the option, utility, or interface is deprecated. Use of the deprecated feature generates a warning. The option, utility, or interface is preserved until the next major (point zero) release. The option, utility, or interface is removed and no longer documented. It is now obsolete. It is also generally a good idea to note its removal in the release notes. Privacy and Confidentiality Most &os; business is done in public. &os; is an open project. Which means that not only can anyone use the source code, but that most of the development process is open to public scrutiny. Certain sensitive matters must remain private or held under embargo. There unfortunately cannot be complete transparency. As a &os; developer you will have a certain degree of privileged access to information. Consequently you are expected to respect certain requirements for confidentiality. Sometimes the need for confidentiality comes from external collaborators or has a specific time limit. Mostly though, it is a matter of not releasing private communications. The Security Officer has sole control over the release of security advisories. Where there are security problems that affect many different operating systems, &os; frequently depends on early access to be able to prepare advisories for coordinated release. Unless &os; developers can be trusted to maintain security, such early access will not be made available. The Security Officer is responsible for controlling pre-release access to information about vulnerabilities, and for timing the release of all advisories. He may request help under condition of confidentiality from any developer with relevant knowledge to prepare security fixes. Communications with Core are kept confidential for as long as necessary. Communications to core will initially be treated as confidential. Eventually however, most of Core's business will be summarized into the monthly or quarterly core reports. Care will be taken to avoid publicising any sensitive details. Records of some particularly sensitive subjects may not be reported on at all and will be retained only in Core's private archives. Non-disclosure Agreements may be required for access to certain commercially sensitive data. Access to certain commercially sensitive data may only be available under a Non-Disclosure Agreement. The FreeBSD Foundation legal staff must be consulted before any binding agreements are entered into. Private communications must not be made public without permission. Beyond the specific requirements above there is a general expectation not to publish private communications between developers without the consent of all parties involved. Ask permission before forwarding a message onto a public mailing list, or posting it to a forum or website that can be accessed by other than the original correspondents. Communications on project-only or restricted access channels must be kept private. Similarly to personal communications, certain internal communications channels, including &os; Committer only mailing lists and restricted access IRC channels are considered private communications. Permission is required to publish material from these sources. Core may approve publication. Where it is impractical to obtain permission due to the number of correspondents or where permission to publish is unreasonably withheld, Core may approve release of such private matters that merit more general publication.
Support for Multiple Architectures &os; is a highly portable operating system intended to function on many different types of hardware architectures. Maintaining clean separation of Machine Dependent (MD) and Machine Independent (MI) code, as well as minimizing MD code, is an important part of our strategy to remain agile with regards to current hardware trends. Each new hardware architecture supported by &os; adds substantially to the cost of code maintenance, toolchain support, and release engineering. It also dramatically increases the cost of effective testing of kernel changes. As such, there is strong motivation to differentiate between classes of support for various architectures while remaining strong in a few key architectures that are seen as the &os; target audience. Statement of General Intent The &os; Project targets "production quality commercial off-the-shelf (COTS) workstation, server, and high-end embedded systems". By retaining a focus on a narrow set of architectures of interest in these environments, the &os; Project is able to maintain high levels of quality, stability, and performance, as well as minimize the load on various support teams on the project, such as the ports team, documentation team, security officer, and release engineering teams. Diversity in hardware support broadens the options for &os; consumers by offering new features and usage opportunities (such as support for 64-bit CPUs, use in embedded environments, etc.), but these benefits must always be carefully considered in terms of the real-world maintenance cost associated with additional platform support. The &os; Project differentiates platform targets into four tiers. Each tier includes a specification of the requirements for an architecture to be in that tier, as well as specifying the obligations of developers with regards to the platform. In addition, a policy is defined regarding the circumstances required to change the tier of an architecture. Tier 1: Fully Supported Architectures Tier 1 platforms are fully supported by the security officer, release engineering, and toolchain maintenance staff. New features added to the operating system must be fully functional across all Tier 1 architectures for every release (features which are inherently architecture-specific, such as support for hardware device drivers, may be exempt from this requirement). In general, all Tier 1 platforms must have build and test automation support either in the FreeBSD.org cluster, or easily available for all developers. Embedded platforms may substitute an emulator available in the FreeBSD.org cluster for actual hardware. Tier 1 architectures are expected to be Production Quality with respects to all aspects of the &os; operating system, including installation and development environments. Tier 1 architectures are expected to be completely integrated into the source tree and have all features necessary to produce an entire system relevant for that target architecture. Tier 1 architectures generally have at least 6 active developers. Tier 1 architectures are expected to be fully supported by the ports system. All the ports should build on a Tier 1 platform, or have the appropriate filters to prevent the inappropriate ones from building there. The packaging system must support all Tier 1 architectures. To ensure an architecture's Tier 1 status, proponents of that architecture must show that all relevant packages can be built on that platform. Tier 1 embedded architectures must be able to cross-build packages on at least one other Tier 1 architecture. The packages must be the most relevant for the platform, but may be a non-empty subset of those that build natively. Tier 1 architectures must be fully documented. All basic operations need to be covered by the handbook or other documents. All relevant integration documentation must also be integrated into the tree, or readily available. Current Tier 1 platforms are &arch.i386; and &arch.amd64;. Tier 2: Developmental Architectures Tier 2 platforms are not supported by the security officer and release engineering teams. Platform maintainers are responsible for toolchain support in the tree. The toolchain maintainers are expected to work with the platform maintainers to refine these changes. Major new toolchain components are allowed to break support for Tier 2 architectures if the &os;-local changes have not been incorporated upstream. The toolchain maintainers are expected to provide prompt review of any proposed changes and cannot block, through their inaction, changes going into the tree. New features added to &os; should be feasible to implement on these platforms, but an implementation is not required before the feature may be added to the &os; source tree. New features that may be difficult to implement on Tier 2 architectures should provide a means of disabling them on those architectures. The implementation of a Tier 2 architecture may be committed to the main &os; tree as long as it does not interfere with production work on Tier 1 platforms, or substantially with other Tier 2 platforms. Before a Tier 2 platform can be added to the &os; base source tree, the platform must be able to boot multi-user on actual hardware. Generally, there must be at least three active developers working on the platform. Tier 2 architectures are usually systems targeted at Tier 1 support, but that are still under development. Architectures reaching end of life may also be moved from Tier 1 status to Tier 2 status as the availability of resources to continue to maintain the system in a Production Quality state diminishes. Well supported niche architectures may also be Tier 2. Tier 2 architectures have basic support for them integrated into the ports infrastructure. They may have cross compilation support added, at the discretion of portmgr. Some ports must built natively into packages if the package system supports that architecture. If not integrated into the base system, some external patches for the architecture for ports must be available. Tier 2 architectures can be integrated into the &os; handbook. The basics for how to get a system running must be documented, although not necessarily for every single board or system a Tier 2 architecture supports. The supported hardware list must exist and be relatively recent. It should be integrated into the &os; documentation. Current Tier 2 platforms are &arch.arm;, &arch.arm64;, &arch.ia64; (through &os; 10), &arch.mips;, &arch.pc98; (through &os; 11), &arch.powerpc;, and &arch.sparc64;. Tier 3: Experimental Architectures Tier 3 platforms are not supported by the security officer and release engineering teams. At the discretion of the toolchain maintainers, they may be supported in the toolchain. Tier 3 platforms are architectures in the early stages of development, for non-mainstream hardware platforms, or which are considered legacy systems unlikely to see broad future use. Initial support for Tier 3 platforms is worked on in external SCM repositories. The transition to &os;'s subversion takes place after the platform boots multi-user on hardware; sharing via subversion is needed for wider exposure; and multiple developers are actively working on the platform. Platforms that transition to Tier 3 status may be removed from the tree if they are no longer actively supported by the &os; developer community at the discretion of the release engineer. Tier 3 platforms may have ports support, either integrated or external, but do not require it. Tier 3 platforms must have the basics documented for how to build a kernel and how to boot it on at least one target hardware or emulation environment. This documentation need not be integrated into the &os; tree. Current Tier 3 platforms are &arch.riscv;. Tier 4: Unsupported Architectures Tier 4 systems are not supported in any form by the project. All systems not otherwise classified into a support tier are Tier 4 systems. The &arch.ia64; platform is transitioning to Tier 4 status in &os; 11. The &arch.pc98; platform is transitioning to Tier 4 status in &os; 12. Policy on Changing the Tier of an Architecture Systems may only be moved from one tier to another by approval of the &os; Core Team, which shall make that decision in collaboration with the Security Officer, Release Engineering, and toolchain maintenance teams. Ports Specific FAQ Adding a New Port How do I add a new port? First, please read the section about repository copies. The easiest way to add a new port is the addport script located in the ports/Tools/scripts directory. It adds a port from the directory specified, determining the category automatically from the port Makefile. It also adds an entry to the port's category Makefile. It was written by &a.mharo.email;, &a.will.email;, and &a.garga.email;. When sending questions about this script to the &a.ports;, please also CC &a.crees.email;, the current maintainer. Any other things I need to know when I add a new port? Check the port, preferably to make sure it compiles and packages correctly. This is the recommended sequence: &prompt.root; make install &prompt.root; make package &prompt.root; make deinstall &prompt.root; pkg add package you built above &prompt.root; make deinstall &prompt.root; make reinstall &prompt.root; make package The Porters Handbook contains more detailed instructions. Use &man.portlint.1; to check the syntax of the port. You do not necessarily have to eliminate all warnings but make sure you have fixed the simple ones. If the port came from a submitter who has not contributed to the Project before, add that person's name to the Additional Contributors section of the &os; Contributors List. Close the PR if the port came in as a PR. To close a PR, change the state to Issue Resolved and the resolution as Fixed. Removing an Existing Port How do I remove an existing port? First, please read the section about repository copies. Before you remove the port, you have to verify there are no other ports depending on it. Make sure there is no dependency on the port in the ports collection: The port's PKGNAME appears in exactly one line in a recent INDEX file. No other ports contains any reference to the port's directory or PKGNAME in their Makefiles When using Git, consider using git grep, it is much faster than grep -r. Then, remove the port: Remove the port's files and directory with svn remove. Remove the SUBDIR listing of the port in the parent directory Makefile. Add an entry to ports/MOVED. Search for entries in ports/security/vuxml/vuln.xml and adjust them accordingly. In particular, check for previous packages with the new name which version could include the new port. Remove the port from ports/LEGAL if it is there. Alternatively, you can use the rmport script, from ports/Tools/scripts. This script was written by &a.vd.email;. When sending questions about this script to the &a.ports;, please also CC &a.crees.email;, the current maintainer. Re-adding a Deleted Port How do I re-add a deleted port? This is essentially the reverse of deleting a port. Do not use svn add to add the port. Follow these steps. If they are unclear, or are not working, ask for help, do not just svn add the port. Figure out when the port was removed. Use this list, or look for the port on freshports, and then copy the last living revision of the port: &prompt.user; cd /usr/ports/category &prompt.user; svn cp 'svn+ssh://repo.freebsd.org/ports/head/category/portname/@XXXXXX' portname Pick the revision that is just before the removal. For example, if the revision where it was removed is 269874, use 269873. It is also possible to specify a date. In that case, pick a date that is before the removal but after the last commit to the port. &prompt.user; cd /usr/ports/category &prompt.user; svn cp 'svn+ssh://repo.freebsd.org/ports/head/category/portname/@{YYYY-MM-DD}' portname Make the changes necessary to get the port working again. If it was deleted because the distfiles are no longer available, either volunteer to host the distfiles, or find someone else to do so. If some files have been added, or were removed during the resurrection process, use svn add or svn remove to make sure all the files in the port will be committed. Restore the SUBDIR listing of the port in the parent directory Makefile, keeping the entries sorted. Delete the port entry from ports/MOVED. If the port had an entry in ports/LEGAL, restore it. svn commit these changes, preferably in one step. The addport script mentioned in now detects when the port to add has previously existed, and attempts to handle all except the ports/LEGAL step automatically. Repository Copies When do we need a repository copy? When you want to add a port that is related to any port that is already in the tree in a separate directory, you have to do a repository copy. Here related means it is a different version or a slightly modified version. Examples are print/ghostscript* (different versions) and x11-wm/windowmaker* (English-only and internationalized version). Another example is when a port is moved from one subdirectory to another, or when the name of a directory must be changed because the authors renamed their software even though it is a descendant of a port already in a tree. What do I need to do? With Subversion, a repo copy can be done by any committer: Doing a repo copy: Verify that the target directory does not exist. Use svn up to make certain the original files, directories, and checkout information is current. Use svn move or svn copy to do the repo copy. Upgrade the copied port to the new version. Remember to add or change the PKGNAMEPREFIX or PKGNAMESUFFIX so there are no duplicate ports with the same name. In some rare cases it may be necessary to change the PORTNAME instead of adding PKGNAMEPREFIX or PKGNAMESUFFIX, but this is only done when it is really needed — for example, using an existing port as the base for a very similar program with a different name, or upgrading a port to a new upstream version which actually changes the distribution name, like the transition from textproc/libxml to textproc/libxml2. In most cases, adding or changing PKGNAMEPREFIX or PKGNAMESUFFIX suffices. Add the new subdirectory to the SUBDIR listing in the parent directory Makefile. You can run make checksubdirs in the parent directory to check this. If the port changed categories, modify the CATEGORIES line of the port's Makefile accordingly Add an entry to ports/MOVED, if you remove the original port. Commit all changes on one commit. When removing a port: Perform a thorough check of the ports collection for any dependencies on the old port location/name, and update them. Running grep on INDEX is not enough because some ports have dependencies enabled by compile-time options. A full grep -r of the ports collection is recommended. Remove the old port and the old SUBDIR entry. Add an entry to ports/MOVED. After repo moves (rename operations where a port is copied and the old location is removed): Follow the same steps that are outlined in the previous two entries, to activate the new location of the port and remove the old one. Ports Freeze What is a ports freeze? A ports freeze was a restricted state the ports tree was put in before a release. It was used to ensure a higher quality for the packages shipped with a release. It usually lasted a couple of weeks. During that time, build problems were fixed, and the release packages were built. This practice is no longer used, as the packages for the releases are built from the current stable, quarterly branch. For more information on how to merge commits to the quarterly branch, see . Quarterly Branches What is the procedure to request authorization for merging a commit to the quarterly branch? When doing the commit, add the branch name to the MFH: line, for example: MFH: 2014Q1 It will automatically notify the &a.ports-secteam; and the &a.portmgr;. They will then decide if the commit can be merged and answer with the procedure. If the commit has already been made, send an email to the &a.ports-secteam; and the &a.portmgr; with the revision number and a small description of why the commit needs to be merged. Are there any changes that can be committed without approval? The following blanket approvals are in effect: These fixes must be tested on the quarterly branch. Fixes that do not result in a change in contents of the resulting package. For example: pkg-descr: WWW: URL updates (existing 404, moved or incorrect) Build, runtime or packaging fixes, if the quarterly branch version is currently broken. Missing dependencies (detected, linked against but not registered via *_DEPENDS). Fixing shebangs, stripping installed libraries and binaries, and plist fixes. Backport of security and reliability fixes which only result in PORTREVISION bumps and no changes to enabled features. for example, adding a patch fixing a buffer overflow. Adding/fixing CONFLICTS. Web Browsers, browser plugins, and their required dependencies. No unauthorized commits can ever be made without approval of either &a.ports-secteam; or &a.portmgr;. What is the procedure for merging commits to the quarterly branch? A script is provided to automate merging a specific commit: ports/Tools/scripts/mfh. It is used as follows: &prompt.user; /usr/ports/Tools/scripts/mfh 380362 U 2015Q1 Checked out revision 380443.

(no = start a shell) [y/n] At that point, the script will either open a shell for you to fix things, or open your text editor with the commit message all prepared and then commit the merge.

[y/n] Creating a New Category What is the procedure for creating a new category? Please see Proposing a New Category in the Porter's Handbook. Once that procedure has been followed and the PR has been assigned to the &a.portmgr;, it is their decision whether or not to approve it. If they do, it is their responsibility to: Perform any needed moves. (This only applies to physical categories.) Update the VALID_CATEGORIES definition in ports/Mk/bsd.port.mk. Assign the PR back to you. What do I need to do to implement a new physical category? Upgrade each moved port's Makefile. Do not connect the new category to the build yet. To do this, you will need to: Change the port's CATEGORIES (this was the point of the exercise, remember?) The new category is listed first. This will help to ensure that the PKGORIGIN is correct. Run a make describe. Since the top-level make index that you will be running in a few steps is an iteration of make describe over the entire ports hierarchy, catching any errors here will save you having to re-run that step later on. If you want to be really thorough, now might be a good time to run &man.portlint.1;. Check that the PKGORIGINs are correct. The ports system uses each port's CATEGORIES entry to create its PKGORIGIN, which is used to connect installed packages to the port directory they were built from. If this entry is wrong, common port tools like &man.pkg.version.1; and &man.portupgrade.1; fail. To do this, use the chkorigin.sh tool: env PORTSDIR=/path/to/ports sh -e /path/to/ports/Tools/scripts/chkorigin.sh. This will check every port in the ports tree, even those not connected to the build, so you can run it directly after the move operation. Hint: do not forget to look at the PKGORIGINs of any slave ports of the ports you just moved! On your own local system, test the proposed changes: first, comment out the SUBDIR entries in the old ports' categories' Makefiles; then enable building the new category in ports/Makefile. Run make checksubdirs in the affected category directories to check the SUBDIR entries. Next, in the ports/ directory, run make index. This can take over 40 minutes on even modern systems; however, it is a necessary step to prevent problems for other people. Once this is done, you can commit the updated ports/Makefile to connect the new category to the build and also commit the Makefile changes for the old category or categories. Add appropriate entries to ports/MOVED. Update the documentation by modifying: the list of categories in the Porter's Handbook doc/en_US.ISO8859-1/htdocs/ports. Note that these are now displayed by sub-groups, as specified in doc/en_US.ISO8859-1/htdocs/ports/categories.descriptions. (Note: these are in the docs, not the ports, repository). If you are not a docs committer, you will need to submit a PR for this. Only once all the above have been done, and no one is any longer reporting problems with the new ports, should the old ports be deleted from their previous locations in the repository. It is not necessary to manually update the ports web pages to reflect the new category. This is done automatically via the change to en_US.ISO8859-1/htdocs/ports/categories and the automated rebuild of INDEX. What do I need to do to implement a new virtual category? This is much simpler than a physical category. Only a few modifications are needed: the list of categories in the Porter's Handbook en_US.ISO8859-1/htdocs/ports/categories Miscellaneous Questions How do I know if my port is building correctly or not? The packages are built multiple times each week. If a port fails, the maintainer will receive an email from pkg-fallout@FreeBSD.org. Reports for all the package builds (official, experimental, and non-regression) are aggregated at pkg-status.FreeBSD.org. I added a new port. Do I need to add it to the INDEX? No. The file can either be generated by running make index, or a pre-generated version can be downloaded with make fetchindex. Are there any other files I am not allowed to touch? Any file directly under ports/, or any file under a subdirectory that starts with an uppercase letter (Mk/, Tools/, etc.). In particular, the &a.portmgr; is very protective of ports/Mk/bsd.port*.mk so do not commit changes to those files unless you want to face their wrath. What is the proper procedure for updating the checksum for a port distfile when the file changes without a version change? When the checksum for a distribution file is updated due to the author updating the file without changing the port revision, the commit message includes a summary of the relevant diffs between the original and new distfile to ensure that the distfile has not been corrupted or maliciously altered. If the current version of the port has been in the ports tree for a while, a copy of the old distfile will usually be available on the ftp servers; otherwise the author or maintainer should be contacted to find out why the distfile has changed. How can an experimental test build of the ports tree (exp-run) be requested? An exp-run must be completed before patches with a significant ports impact are committed. The patch can be against the ports tree or the base system. Full package builds will be done with the patches provided by the submitter, and the submitter is required to fix detected problems (fallout) before commit. Go to the Bugzilla new PR page. Select the product your patch is about. Fill in the bug report as normal. Remember to attach the patch. If at the top it says Show Advanced Fields click on it. It will now say Hide Advanced Fields. Many new fields will be available. If it already says Hide Advanced Fields, no need to do anything. In the Flags section, set the exp-run one to ?. As for all other fields, hovering the mouse over any field shows more details. Submit. Wait for the build to run. &a.portmgr; will replies with a possible fallout. Depending on the fallout: If there is no fallout, the procedure stops here, and the change can be committed, pending any other approval required. If there is fallout, it must be fixed, either by fixing the ports directly in the ports tree, or adding to the submitted patch. When this is done, go back to step 6 saying the fallout was fixed and wait for the exp-run to be run again. Repeat as long as there are broken ports. Issues Specific to Developers Who Are Not Committers A few people who have access to the &os; machines do not have commit bits. Almost all of this document will apply to these developers as well (except things specific to commits and the mailing list memberships that go with them). In particular, we recommend that you read: Administrative Details Conventions Get your mentor to add you to the Additional Contributors (doc/en_US.ISO8859-1/articles/contributors/contrib.additional.xml), if you are not already listed there.

From now on, every new vendor release of that file will need to have patches merged in by hand. From now on, every new vendor release of that file will need to have patches verified by hand. How do I add a new file to a branch? To add a file onto a branch, simply checkout or update to the branch you want to add to and then add the file using the add operation as you normally would. This works fine for the doc and ports trees. The src tree uses SVN and requires more care because of the mergeinfo properties. See the Subversion Primer for details on how to perform an MFC. How do I access people.FreeBSD.org to put up personal or project information? people.FreeBSD.org is the same as freefall.FreeBSD.org. Just create a public_html directory.

However, a project model summarising how the project is structured is needed because of the increasing amount of project members. This goes hand-in-hand with Brooks' law that adding another person to a late project will make it later since it will increase the communication needs . A project model is a tool to reduce the communication needs. This paper will provide such a project model and is donated to the FreeBSD Documentation project where it can evolve together with the project so that it can at any point in time reflect the way the project works. It is based on . I would like to thank the following people for taking the time to explain things that were unclear to me and for proofreading the document. Andrey A. Chernov ache@freebsd.org Bruce A. Mah bmah@freebsd.org Dag-Erling Smørgrav des@freebsd.org Giorgos Keramidaskeramida@freebsd.org Ingvil Hovig ingvil.hovig@skatteetaten.no Jesper Holckjeh.inf@cbs.dk John Baldwin jhb@freebsd.org John Polstra jdp@freebsd.org Kirk McKusick mckusick@freebsd.org Mark Linimon linimon@freebsd.org Marleen Devos Niels Jørgenssennielsj@ruc.dk Nik Clayton nik@freebsd.org Poul-Henning Kamp phk@freebsd.org Simon L. Nielsen simon@freebsd.org Overview A project model is a means to reduce the communications overhead in a project. As shown by , increasing the number of project participants increases the communication in the project exponentionally. FreeBSD has during the past few years increased both its mass of active users and committers, and the communication in the project has risen accordingly. This project model will serve to reduce this overhead by providing an up-to-date description of the project. During the Core elections in 2002, Mark Murray stated I am opposed to a long rule-book, as that satisfies lawyer-tendencies, and is counter to the technocentricity that the project so badly needs. . This project model is not meant to be a tool to justify creating impositions for developers, but as a tool to facilitate coordination. It is meant as a description of the project, with an overview of how the different processes are executed. It is an introduction to how the FreeBSD project works. The FreeBSD project model will be described as of July 1st, 2004. It is based on the Niels Jørgensen's paper , FreeBSD's official documents, discussions on FreeBSD mailing lists and interviews with developers. After providing definitions of terms used, this document will outline the organisational structure (including role descriptions and communication lines), discuss the methodology model and after presenting the tools used for process control, it will present the defined processes. Finally it will outline major sub-projects of the FreeBSD project. , Section 1.2 and 1.3 give the vision and the architectural guidelines for the project. The vision is To produce the best UNIX-like operating system package possible, with due respect to the original software tools ideology as well as usability, performance and stability. The architectural guidelines help determine whether a problem that someone wants to be solved is within the scope of the project Definitions
Activity An activity is an element of work performed during the course of a project . It has an output and leads towards an outcome. Such an output can either be an input to another activity or a part of the process' delivery.
Process A process is a series of activities that lead towards a particular outcome. A process can consist of one or more sub-processes. An example of a process is software design.
Hat A hat is synonymous with role. A hat has certain responsibilities in a process and for the process outcome. The hat executes activities. It is well defined what issues the hat should be contacted about by the project members and people outside the project.
Outcome An outcome is the final output of the process. This is synonymous with deliverable, that is defined as any measurable, tangible, verifiable outcome, result or item that must be produced to complete a project or part of a project. Often used more narrowly in reference to an external deliverable, which is a deliverable that is subject to approval by the project sponsor or customer by . Examples of outcomes are a piece of software, a decision made or a report written.
FreeBSD When saying FreeBSD we will mean the BSD derivative UNIX-like operating system FreeBSD, whereas when saying the FreeBSD Project we will mean the project organisation.
Organisational structure While no-one takes ownership of FreeBSD, the FreeBSD organisation is divided into core, committers and contributors and is part of the FreeBSD community that lives around it.
The FreeBSD Project's structure
Number of committers has been determined by going through CVS logs from January 1st, 2004 to December 31st, 2004 and contributors by going through the list of contributions and problem reports. The main resource in the FreeBSD community is its developers: the committers and contributors. It is with their contributions that the project can move forward. Regular developers are referred to as contributors. As by January 1st, 2003, there are an estimated 5500 contributors on the project. Committers are developers with the privilege of being able to commit changes. These are usually the most active developers who are willing to spend their time not only integrating their own code but integrating code submitted by the developers who do not have this privilege. They are also the developers who elect the core team, and they have access to closed discussions. The project can be grouped into four distinct separate parts, and most developers will focus their involvement in one part of FreeBSD. The four parts are kernel development, userland development, ports and documentation. When referring to the base system, both kernel and userland is meant. This split changes our triangle to look like this:
The FreeBSD Project's structure with committers in categories
Number of committers per area has been determined by going through CVS logs from January 1st, 2004 to December 31st, 2004. Note that many committers work in multiple areas, making the total number higher than the real number of committers. The total number of committers at that time was 269. Committers fall into three groups: committers who are only concerned with one area of the project (for instance file systems), committers who are involved only with one sub-project and committers who commit to different parts of the code, including sub-projects. Because some committers work on different parts, the total number in the committers section of the triangle is higher than in the above triangle. The kernel is the main building block of FreeBSD. While the userland applications are protected against faults in other userland applications, the entire system is vulnerable to errors in the kernel. This, combined with the vast amount of dependencies in the kernel and that it is not easy to see all the consequences of a kernel change, demands developers with a relative full understanding of the kernel. Multiple development efforts in the kernel also requires a closer coordination than userland applications do. The core utilities, known as userland, provide the interface that identifies FreeBSD, both user interface, shared libraries and external interfaces to connecting clients. Currently, 162 people are involved in userland development and maintenance, many being maintainers for their own part of the code. Maintainership will be discussed in the section. Documentation is handled by and includes all documents surrounding the FreeBSD project, including the web pages. There were during 2004 101 people making commits to the FreeBSD Documentation Project. Ports is the collection of meta-data that is needed to make software packages build correctly on FreeBSD. An example of a port is the port for the web-browser Mozilla. It contains information about where to fetch the source, what patches to apply and how, and how the package should be installed on the system. This allows automated tools to fetch, build and install the package. As of this writing, there are more than 12600 ports available. Statistics are generated by counting the number of entries in the file fetched by portsdb by April 1st, 2005. portsdb is a part of the port sysutils/portupgrade. , ranging from web servers to games, programming languages and most of the application types that are in use on modern computers. Ports will be discussed further in the section .
Methodology model
Development model There is no defined model for how people write code in FreeBSD. However, Niels Jørgenssen has suggested a model of how written code is integrated into the project.
Jørgenssen's model for change integration
The development release is the FreeBSD-CURRENT ("-CURRENT") branch and the production release is the FreeBSD-STABLE branch ("-STABLE") . This is a model for one change, and shows that after coding, developers seek community review and try integrating it with their own systems. After integrating the change into the development release, called FreeBSD-CURRENT, it is tested by many users and developers in the FreeBSD community. After it has gone through enough testing, it is merged into the production release, called FreeBSD-STABLE. Unless each stage is finished successfully, the developer needs to go back and make modifications in the code and restart the process. To integrate a change with either -CURRENT or -STABLE is called making a commit. Jørgensen found that most FreeBSD developers work individually, meaning that this model is used in parallel by many developers on the different ongoing development efforts. A developer can also be working on multiple changes, so that while he is waiting for review or people to test one or more of his changes, he may be writing another change. As each commit represents an increment, this is a massively incremental model. The commits are in fact so frequent that during one year The period from January 1st, 2004 to December 31st, 2004 was examined to find this number. , 85427 commits were made, making a daily average of 233 commits. Within the code bracket in Jørgensen's figure, each programmer has his own working style and follows his own development models. The bracket could very well have been called development as it includes requirements gathering and analysis, system and detailed design, implementation and verification. However, the only output from these stages is the source code or system documentation. From a stepwise model's perspective (such as the waterfall model), the other brackets can be seen as further verification and system integration. This system integration is also important to see if a change is accepted by the community. Up until the code is committed, the developer is free to choose how much to communicate about it to the rest of the project. In order for -CURRENT to work as a buffer (so that bright ideas that had some undiscovered drawbacks can be backed out) the minimum time a commit should be in -CURRENT before merging it to -STABLE is 3 days. Such a merge is referred to as an MFC (Merge From Current). It is important to notice the word change. Most commits do not contain radical new features, but are maintenance updates. The only exceptions from this model are security fixes and changes to features that are deprecated in the -CURRENT branch. In these cases, changes can be committed directly to the -STABLE branch. In addition to many people working on the project, there are many related projects to the FreeBSD Project. These are either projects developing brand new features, sub-projects or projects whose outcome is incorporated into FreeBSD For instance, the development of the Bluetooth stack started as a sub-project until it was deemed stable enough to be merged into the -CURRENT branch. Now it is a part of the core FreeBSD system. . These projects fit into the FreeBSD Project just like regular development efforts: they produce code that is integrated with the FreeBSD Project. However, some of them (like Ports and Documentation) have the privilege of being applicable to both branches or commit directly to both -CURRENT and -STABLE. There is no standards to how design should be done, nor is design collected in a centralised repository. The main design is that of 4.4BSD. According to Kirk McKusick, after 20 years of developing UNIX operating systems, the interfaces are for the most part figured out. There is therefore no need for much design. However, new applications of the system and new hardware leads to some implementations being more beneficial than those that used to be preferred. One example is the introduction of web browsing that made the normal TCP/IP connection a short burst of data rather than a steady stream over a longer period of time. As design is a part of the Code bracket in Jørgenssen's model, it is up to every developer or sub-project how this should be done. Even if the design should be stored in a central repository, the output from the design stages would be of limited use as the differences of methodologies would make them poorly if at all interoperable. For the overall design of the project, the project relies on the sub-projects to negotiate fit interfaces between each other rather than to dictate interfacing.
Release branches The releases of FreeBSD is best illustrated by a tree with many branches where each major branch represents a major version. Minor versions are represented by branches of the major branches. In the following release tree, arrows that follow one-another in a particular direction represent a branch. Boxes with full lines and diamonds represent official releases. Boxes with dotted lines represent the development branch at that time. Security branches are represented by ovals. Diamonds differ from boxes in that they represent a fork, meaning a place where a branch splits into two branches where one of the branches becomes a sub-branch. For example, at 4.0-RELEASE the 4.0-CURRENT branch split into 4-STABLE and 5.0-CURRENT. At 4.5-RELEASE, the branch forked off a security branch called RELENG_4_5.
The FreeBSD release tree
The latest -CURRENT version is always referred to as -CURRENT, while the latest -STABLE release is always referred to as -STABLE. In this figure, -STABLE refers to 4-STABLE while -CURRENT refers to 5.0-CURRENT following 5.0-RELEASE. A major release is always made from the -CURRENT branch. However, the -CURRENT branch does not need to fork at that point in time, but can focus on stabilising. An example of this is that following 3.0-RELEASE, 3.1-RELEASE was also a continuation of the -CURRENT-branch, and -CURRENT did not become a true development branch until this version was released and the 3-STABLE branch was forked. When -CURRENT returns to becoming a development branch, it can only be followed by a major release. 5-STABLE is predicted to be forked off 5.0-CURRENT at around 5.3-RELEASE. It is not until 5-STABLE is forked that the development branch will be branded 6.0-CURRENT. A minor release is made from the -CURRENT branch following a major release, or from the -STABLE branch. Following and including, 4.3-RELEASE The first release this actually happened for was 4.5-RELEASE, but security branches were at the same time created for 4.3-RELEASE and 4.4-RELEASE. , when a minor release has been made, it becomes a security branch. This is meant for organisations that do not want to follow the -STABLE branch and the potential new/changed features it offers, but instead require an absolutely stable environment, only updating to implement security updates. There is a terminology overlap with respect to the word "stable", which leads to some confusion. The -STABLE branch is still a development branch, whose goal is to be useful for most people. If it is never acceptable for a system to get changes that are not announced at the time it is deployed, that system should run a security branch. Each update to a security branch is called a patchlevel. For every security enhancement that is done, the patchlevel number is increased, making it easy for people tracking the branch to see what security enhancements they have implemented. In cases where there have been especially serious security flaws, an entire new release can be made from a security branch. An example of this is 4.6.2-RELEASE.
Model summary To summarise, the development model of FreeBSD can be seen as the following tree:
The overall development model
The tree of the FreeBSD development with ongoing development efforts and continuous integration. The tree symbolises the release versions with major versions spawning new main branches and minor versions being versions of the main branch. The top branch is the -CURRENT branch where all new development is integrated, and the -STABLE branch is the branch directly below it. Clouds of development efforts hang over the project where developers use the development models they see fit. The product of their work is then integrated into -CURRENT where it undergoes parallel debugging and is finally merged from -CURRENT into -STABLE. Security fixes are merged from -STABLE to the security branches.
Hats Many committers have a special area of responsibility. These roles are called hats. These hats can be either project roles, such as public relations officer, or maintainer for a certain area of the code. Because this is a project where people give voluntarily of their spare time, people with assigned hats are not always available. They must therefore appoint a deputy that can perform the hat's role in his or her absence. The other option is to have the role held by a group. Many of these hats are not formalised. Formalised hats have a charter stating the exact purpose of the hat along with its privileges and responsibilities. The writing of such charters is a new part of the project, and has thus yet to be completed for all hats. These hat descriptions are not such a formalisation, rather a summary of the role with links to the charter where available and contact addresses.
General Hats
Contributor A Contributor contributes to the FreeBSD project either as a developer, as an author, by sending problem reports, or in other ways contributing to the progress of the project. A contributor has no special privileges in the FreeBSD project.
Committer A person who has the required privileges to add his code or documentation to the repository. A committer has made a commit within the past 12 months. An active committer is a committer who has made an average of one commit per month during that time. It is worth noting that there are no technical barriers to prevent someone, once having gained commit privileges to the main- or a sub-project, to make commits in parts of that project's source the committer did not specifically get permission to modify. However, when wanting to make modifications to parts a committer has not been involved in before, he/she should read the logs to see what has happened in this area before, and also read the MAINTAINER file to see if the maintainer of this part has any special requests on how changes in the code should be made
Core Team The core team is elected by the committers from the pool of committers and serves as the board of directors of the FreeBSD project. It promotes active contributors to committers, assigns people to well-defined hats, and is the final arbiter of decisions involving which way the project should be heading. As by July 1st, 2004, core consisted of 9 members. Elections are held every two years.
Maintainership Maintainership means that that person is responsible for what is allowed to go into that area of the code and has the final say should disagreements over the code occur. This involves proactive work aimed at stimulating contributions and reactive work in reviewing commits. With the FreeBSD source comes the MAINTAINERS file that contains a one-line summary of how each maintainer would like contributions to be made. Having this notice and contact information enables developers to focus on the development effort rather than being stuck in a slow correspondence should the maintainer be unavailable for some time. If the maintainer is unavailable for an unreasonably long period of time, and other people do a significant amount of work, maintainership may be switched without the maintainer's approval. This is based on the stance that maintainership should be demonstrated, not declared. Maintainership of a particular piece of code is a hat that is not held as a group.
Official Hats The official hats in the FreeBSD Project are hats that are more or less formalised and mainly administrative roles. They have the authority and responsibility for their area. The following illustration shows the responsibility lines. After this follows a description of each hat, including who it is held by.
Overview of official hats
All boxes consist of groups of committers, except for the dotted boxes where the holders are not necessarily committers. The flattened circles are sub-projects and consist of both committers and non-committers of the main project.
Documentation project manager architect is responsible for defining and following up documentation goals for the committers in the Documentation project. Hat held by: The DocEng team doceng@FreeBSD.org. The DocEng Charter.
Postmaster The Postmaster is responsible for mail being correctly delivered to the committers' email address. He is also responsible for ensuring that the mailing lists work and should take measures against possible disruptions of mail such as having troll-, spam- and virus-filters. Hat currently held by: the Postmaster Team postmaster@FreeBSD.org.
Release Coordination The responsibilities of the Release Engineering Team are Setting, publishing and following a release schedule for official releases Documenting and formalising release engineering procedures Creation and maintenance of code branches Coordinating with the Ports and Documentation teams to have an updated set of packages and documentation released with the new releases Coordinating with the Security team so that pending releases are not affected by recently disclosed vulnerabilities. Further information about the development process is available in the section. Hat held by: the Release Engineering team re@FreeBSD.org. The Release Engineering Charter.
Public Relations & Corporate Liaison The Public Relations & Corporate Liaison's responsibilities are: Making press statements when happenings that are important to the FreeBSD Project happen. Being the official contact person for corporations that are working close with the FreeBSD Project. Take steps to promote FreeBSD within both the Open Source community and the corporate world. Handle the freebsd-advocacy mailing list. This hat is currently not occupied.
Security Officer The Security Officer's main responsibility is to coordinate information exchange with others in the security community and in the FreeBSD project. The Security Officer is also responsible for taking action when security problems are reported and promoting proactive development behavior when it comes to security. Because of the fear that information about vulnerabilities may leak out to people with malicious intent before a patch is available, only the Security Officer, consisting of an officer, a deputy and two members, receive sensitive information about security issues. However, to create or implement a patch, the Security Officer has the Security Officer Team security-team@FreeBSD.org to help do the work.
Source Repository Manager The Source Repository Manager is the only one who is allowed to directly modify the repository without using the tool. It is his/her responsibility to ensure that technical problems that arise in the repository are resolved quickly. The source repository manager has the authority to back out commits if this is necessary to resolve a SVN technical problem. Hat held by: the Source Repository Manager clusteradm@FreeBSD.org.
Election Manager The Election Manager is responsible for the process. The manager is responsible for running and maintaining the election system, and is the final authority should minor unforeseen events happen in the election process. Major unforeseen events have to be discussed with the Hat held only during elections.
Web site Management The Web site Management hat is responsible for coordinating the rollout of updated web pages on mirrors around the world, for the overall structure of the primary web site and the system it is running upon. The management needs to coordinate the content with and acts as maintainer for the www tree. Hat held by: the FreeBSD Webmasters www@FreeBSD.org.
Ports Manager The Ports Manager acts as a liaison between and the core project, and all requests from the project should go to the ports manager. Hat held by: the Ports Management Team portmgr@FreeBSD.org. The Portmgr charter.
Standards The Standards hat is responsible for ensuring that FreeBSD complies with the standards it is committed to , keeping up to date on the development of these standards and notifying FreeBSD developers of important changes that allows them to take a proactive role and decrease the time between a standards update and FreeBSD's compliancy. Hat currently held by: Garrett Wollman wollman@FreeBSD.org.
Core Secretary The Core Secretary's main responsibility is to write drafts to and publish the final Core Reports. The secretary also keeps the core agenda, thus ensuring that no balls are dropped unresolved. Hat currently held by: &a.matthew.email;.
Bugmeister The Bugmeister is responsible for ensuring that the maintenance database is in working order, that the entries are correctly categorised and that there are no invalid entries. Hat currently held by: the Bugmeister Team bugmeister@FreeBSD.org.
Donations Liaison Officer The task of the donations liaison officer is to match the developers with needs with people or organisations willing to make a donation. The Donations Liaison Charter is available here Hat held by: the Donations Liaison Office donations@FreeBSD.org.
Admin (Also called FreeBSD Cluster Admin) The admin team consists of the people responsible for administrating the computers that the project relies on for its distributed work and communication to be synchronised. It consists mainly of those people who have physical access to the servers. Hat held by: the Admin team admin@FreeBSD.org.
Process dependent hats
Report originator The person originally responsible for filing a Problem Report.
Bugbuster A person who will either find the right person to solve the problem, or close the PR if it is a duplicate or otherwise not an interesting one.
Mentor A mentor is a committer who takes it upon him/her to introduce a new committer to the project, both in terms of ensuring the new committers setup is valid, that the new committer knows the available tools required in his/her work and that the new committer knows what is expected of him/her in terms of behavior.
Vendor The person(s) or organisation whom external code comes from and whom patches are sent to.
Reviewers People on the mailing list where the request for review is posted.
Processes The following section will describe the defined project processes. Issues that are not handled by these processes happen on an ad-hoc basis based on what has been customary to do in similar cases.
Adding new and removing old committers The Core team has the responsibility of giving and removing commit privileges to contributors. This can only be done through a vote on the core mailing list. The ports and documentation sub-projects can give commit privileges to people working on these projects, but have to date not removed such privileges. Normally a contributor is recommended to core by a committer. For contributors or outsiders to contact core asking to be a committer is not well thought of and is usually rejected. If the area of particular interest for the developer potentially overlaps with other committers' area of maintainership, the opinion of those maintainers is sought. However, it is frequently this committer that recommends the developer. When a contributor is given committer status, he is assigned a mentor. The committer who recommended the new committer will, in the general case, take it upon himself to be the new committers mentor. When a contributor is given his commit bit, a -signed email is sent from either , or nik@freebsd.org to both admins@freebsd.org, the assigned mentor, the new committer and core confirming the approval of a new account. The mentor then gathers a password line, public key and PGP key from the new committer and sends them to . When the new account is created, the mentor activates the commit bit and guides the new committer through the rest of the initial process.
Process summary: adding a new committer
When a contributor sends a piece of code, the receiving committer may choose to recommend that the contributor is given commit privileges. If he recommends this to core, they will vote on this recommendation. If they vote in favour, a mentor is assigned the new committer and the new committer has to email his details to the administrators for an account to be created. After this, the new committer is all set to make his first commit. By tradition, this is by adding his name to the committers list. Recall that a committer is considered to be someone who has committed code during the past 12 months. However, it is not until after 18 months of inactivity have passed that commit privileges are eligible to be revoked. There are, however, no automatic procedures for doing this. For reactions concerning commit privileges not triggered by time, see section 1.5.8.
Process summary: removing a committer
When Core decides to clean up the committers list, they check who has not made a commit for the past 18 months. Committers who have not done so have their commit bits revoked. It is also possible for committers to request that their commit bit be retired if for some reason they are no longer going to be actively committing to the project. In this case, it can also be restored at a later time by core, should the committer ask. Roles in this process:
Committing code The committing of new or modified code is one of the most frequent processes in the FreeBSD project and will usually happen many times a day. Committing of code can only be done by a committer. Committers commit either code written by themselves, code submitted to them or code submitted through a problem report. When code is written by the developer that is non-trivial, he should seek a code review from the community. This is done by sending mail to the relevant list asking for review. Before submitting the code for review, he should ensure it compiles correctly with the entire tree and that all relevant tests run. This is called pre-commit test. When contributed code is received, it should be reviewed by the committer and tested the same way. When a change is committed to a part of the source that has been contributed from an outside , the maintainer should ensure that the patch is contributed back to the vendor. This is in line with the open source philosophy and makes it easier to stay in sync with outside projects as the patches do not have to be reapplied every time a new release is made. After the code has been available for review and no further changes are necessary, the code is committed into the development branch, -CURRENT. If the change applies for the -STABLE branch or the other branches as well, a Merge From Current ("MFC") countdown is set by the committer. After the number of days the committer chose when setting the MFC have passed, an email will automatically be sent to the committer reminding him to commit it to the -STABLE branch (and possibly security branches as well). Only security critical changes should be merged to security branches. Delaying the commit to -STABLE and other branches allows for parallel debugging where the committed code is tested on a wide range of configurations. This makes changes to -STABLE to contain fewer faults and thus giving the branch its name.
Process summary: A committer commits code
When a committer has written a piece of code and wants to commit it, he first needs to determine if it is trivial enough to go in without prior review or if it should first be reviewed by the developer community. If the code is trivial or has been reviewed and the committer is not the maintainer, he should consult the maintainer before proceeding. If the code is contributed by an outside vendor, the maintainer should create a patch that is sent back to the vendor. The code is then committed and the deployed by the users. Should they find problems with the code, this will be reported and the committer can go back to writing a patch. If a vendor is affected, he can choose to implement or ignore the patch.
Process summary: A contributor commits code
The difference when a contributor makes a code contribution is that he submits the code through the Bugzilla interface. This report is picked up by the maintainer who reviews the code and commits it. Hats included in this process are:
Core election Core elections are held at least every two years. The first Core election was held September 2000 Nine core members are elected. New elections are held if the number of core members drops below seven. New elections can also be held should at least 1/3 of the active committers demand this. When an election is to take place, core announces this at least 6 weeks in advance, and appoints an election manager to run the elections. Only committers can be elected into core. The candidates need to submit their candidacy at least one week before the election starts, but can refine their statements until the voting starts. They are presented in the candidates list. When writing their election statements, the candidates must answer a few standard questions submitted by the election manager. During elections, the rule that a committer must have committed during the 12 past months is followed strictly. Only these committers are eligible to vote. When voting, the committer may vote once in support of up to nine nominees. The voting is done over a period of four weeks with reminders being posted on developers mailing list that is available to all committers. The election results are released one week after the election ends, and the new core team takes office one week after the results have been posted. Should there be a voting tie, this will be resolved by the new, unambiguously elected core members. Votes and candidate statements are archived, but the archives are not publicly available.
Process summary: Core elections
Core announces the election and selects an election manager. He prepares the elections, and when ready, candidates can announce their candidacies through submitting their statements. The committers then vote. After the vote is over, the election results are announced and the new core team takes office. Hats in core elections are:
Development of new features Within the project there are sub-projects that are working on new features. These projects are generally done by one person . Every project is free to organise development as it sees fit. However, when the project is merged to the -CURRENT branch it must follow the project guidelines. When the code has been well tested in the -CURRENT branch and deemed stable enough and relevant to the -STABLE branch, it is merged to the -STABLE branch. The requirements of the project are given by developer wishes, requests from the community in terms of direct requests by mail, Problem Reports, commercial funding for the development of features, or contributions by the scientific community. The wishes that come within the responsibility of a developer are given to that developer who prioritises his time between the request and his wishes. A common way to do this is maintain a TODO-list maintained by the project. Items that do not come within someone's responsibility are collected on TODO-lists unless someone volunteers to take the responsibility. All requests, their distribution and follow-up are handled by the tool. Requirements analysis happens in two ways. The requests that come in are discussed on mailing lists, both within the main project and in the sub-project that the request belongs to or is spawned by the request. Furthermore, individual developers on the sub-project will evaluate the feasibility of the requests and determine the prioritisation between them. Other than archives of the discussions that have taken place, no outcome is created by this phase that is merged into the main project. As the requests are prioritised by the individual developers on the basis of doing what they find interesting, necessary or are funded to do, there is no overall strategy or prioritisation of what requests to regard as requirements and following up their correct implementation. However, most developers have some shared vision of what issues are more important, and they can ask for guidelines from the release engineering team. The verification phase of the project is two-fold. Before committing code to the current-branch, developers request their code to be reviewed by their peers. This review is for the most part done by functional testing, but also code review is important. When the code is committed to the branch, a broader functional testing will happen, that may trigger further code review and debugging should the code not behave as expected. This second verification form may be regarded as structural verification. Although the sub-projects themselves may write formal tests such as unit tests, these are usually not collected by the main project and are usually removed before the code is committed to the current branch. More and more tests are however performed when building the system (make world). These tests are however a very new addition and no systematic framework for these tests have yet been created.
Maintenance It is an advantage to the project to for each area of the source have at least one person that knows this area well. Some parts of the code have designated maintainers. Others have de-facto maintainers, and some parts of the system do not have maintainers. The maintainer is usually a person from the sub-project that wrote and integrated the code, or someone who has ported it from the platform it was written for. sendmail and named are examples of code that has been merged from other platforms. The maintainer's job is to make sure the code is in sync with the project the code comes from if it is contributed code, and apply patches submitted by the community or write fixes to issues that are discovered. The main bulk of work that is put into the FreeBSD project is maintenance. has made a figure showing the life cycle of changes.
Jørgenssen's model for change integration
Here development release refers to the -CURRENT branch while production release refers to the -STABLE branch. The pre-commit test is the functional testing by peer developers when asked to do so or trying out the code to determine the status of the sub-project. Parallel debugging is the functional testing that can trigger more review, and debugging when the code is included in the -CURRENT branch. As of this writing, there were 269 committers in the project. When they commit a change to a branch, that constitutes a new release. It is very common for users in the community to track a particular branch. The immediate existence of a new release makes the changes widely available right away and allows for rapid feedback from the community. This also gives the community the response time they expect on issues that are of importance to them. This makes the community more engaged, and thus allows for more and better feedback that again spurs more maintenance and ultimately should create a better product. Before making changes to code in parts of the tree that has a history unknown to the committer, the committer is required to read the commit logs to see why certain features are implemented the way they are in order not to make mistakes that have previously either been thought through or resolved.
Problem reporting Before &os; 10, &os; included a problem reporting tool called send-pr. Problems include bug reports, feature requests, feature enhancements and notices of new versions of external software that are included in the project. Although send-pr is available, users and developers are encouraged to submit issues using our problem report form. Problem reports are sent to an email address where it is inserted into the Problem Reports maintenance database. A classifies the problem and sends it to the correct group or maintainer within the project. After someone has taken responsibility for the report, the report is being analysed. This analysis includes verifying the problem and thinking out a solution for the problem. Often feedback is required from the report originator or even from the FreeBSD community. Once a patch for the problem is made, the originator may be asked to try it out. Finally, the working patch is integrated into the project, and documented if applicable. It there goes through the regular maintenance cycle as described in section . These are the states a problem report can be in: open, analyzed, feedback, patched, suspended and closed. The suspended state is for when further progress is not possible due to the lack of information or for when the task would require so much work that nobody is working on it at the moment.
Process summary: problem reporting
A problem is reported by the report originator. It is then classified by a bugbuster and handed to the correct maintainer. He verifies the problem and discusses the problem with the originator until he has enough information to create a working patch. This patch is then committed and the problem report is closed. The roles included in this process are: .
Reacting to misbehavior has a number of rules that committers should follow. However, it happens that these rules are broken. The following rules exist in order to be able to react to misbehavior. They specify what actions will result in how long a suspension the committer's commit privileges. Committing during code freezes without the approval of the Release Engineering team - 2 days Committing to a security branch without approval - 2 days Commit wars - 5 days to all participating parties Impolite or inappropriate behavior - 5 days For the suspensions to be efficient, any single core member can implement a suspension before discussing it on the core mailing list. Repeat offenders can, with a 2/3 vote by core, receive harsher penalties, including permanent removal of commit privileges. (However, the latter is always viewed as a last resort, due to its inherent tendency to create controversy). All suspensions are posted to the developers mailing list, a list available to committers only. It is important that you cannot be suspended for making technical errors. All penalties come from breaking social etiquette. Hats involved in this process:
Release engineering The FreeBSD project has a Release Engineering team with a principal release engineer that is responsible for creating releases of FreeBSD that can be brought out to the user community via the net or sold in retail outlets. Since FreeBSD is available on multiple platforms and releases for the different architectures are made available at the same time, the team has one person in charge of each architecture. Also, there are roles in the team responsible for coordinating quality assurance efforts, building a package set and for having an updated set of documents. When referring to the release engineer, a representative for the release engineering team is meant. When a release is coming, the FreeBSD project changes shape somewhat. A release schedule is made containing feature- and code-freezes, release of interim releases and the final release. A feature-freeze means no new features are allowed to be committed to the branch without the release engineers' explicit consent. Code-freeze means no changes to the code (like bugs-fixes) are allowed to be committed without the release engineers explicit consent. This feature- and code-freeze is known as stabilising. During the release process, the release engineer has the full authority to revert to older versions of code and thus "back out" changes should he find that the changes are not suitable to be included in the release. There are three different kinds of releases: .0 releases are the first release of a major version. These are branched of the -CURRENT branch and have a significantly longer release engineering cycle due to the unstable nature of the -CURRENT branch .X releases are releases of the -STABLE branch. They are scheduled to come out every 4 months. .X.Y releases are security releases that follow the .X branch. These come out only when sufficient security fixes have been merged since the last release on that branch. New features are rarely included, and the security team is far more involved in these than in regular releases. For releases of the -STABLE-branch, the release process starts 45 days before the anticipated release date. During the first phase, the first 15 days, the developers merge what changes they have had in -CURRENT that they want to have in the release to the release branch. When this period is over, the code enters a 15 day code freeze in which only bug fixes, documentation updates, security-related fixes and minor device driver changes are allowed. These changes must be approved by the release engineer in advance. At the beginning of the last 15 day period a release candidate is created for widespread testing. Updates are less likely to be allowed during this period, except for important bug fixes and security updates. In this final period, all releases are considered release candidates. At the end of the release process, a release is created with the new version number, including binary distributions on web sites and the creation of a CD-ROM images. However, the release is not considered "really released" until a -signed message stating exactly that, is sent to the mailing list freebsd-announce; anything labelled as a "release" before that may well be in-process and subject to change before the PGP-signed message is sent. Many commercial vendors use these images to create CD-ROMs that are sold in retail outlets. . The releases of the -CURRENT-branch (that is, all releases that end with .0) are very similar, but with twice as long timeframe. It starts 8 weeks prior to the release with announcement of the release time line. Two weeks into the release process, the feature freeze is initiated and performance tweaks should be kept to a minimum. Four weeks prior to the release, an official beta version is made available. Two weeks prior to release, the code is officially branched into a new version. This version is given release candidate status, and as with the release engineering of -STABLE, the code freeze of the release candidate is hardened. However, development on the main development branch can continue. Other than these differences, the release engineering processes are alike. .0 releases go into their own branch and are aimed mainly at early adopters. The branch then goes through a period of stabilisation, and it is not until the decides the demands to stability have been satisfied that the branch becomes -STABLE and -CURRENT targets the next major version. While this for the majority has been with .1 versions, this is not a demand. Most releases are made when a given date that has been deemed a long enough time since the previous release comes. A target is set for having major releases every 18 months and minor releases every 4 months. The user community has made it very clear that security and stability cannot be sacrificed by self-imposed deadlines and target release dates. For slips of time not to become too long with regards to security and stability issues, extra discipline is required when committing changes to -STABLE.
Process summary: release engineering
These are the stages in the release engineering process. Multiple release candidates may be created until the release is deemed stable enough to be released.
Tools The major support tools for supporting the development process are - Perforce, Bugzilla, Mailman, and OpenSSH. These are externally + Bugzilla, Mailman, and OpenSSH. These are externally developed tools and are commonly used in the open source world.
Subversion (SVN) Subversion (SVN) is a system to handle multiple versions of text files and tracking who committed what changes and why. A project lives within a repository and different versions are considered different branches.
Bugzilla Bugzilla is a maintenance database consisting of a set of tools to track bugs at a central site. It supports the bug tracking process for sending and handling bugs as well as querying and updating the database and editing bug reports. The project uses its web interface to send Problem Reports to the projects central Bugzilla server. The committers also have web and command-line clients.
Mailman Mailman is a program that automates the management of mailing lists. The FreeBSD Project uses it to run 16 general lists, 60 technical lists, 4 limited lists and 5 lists with CVS commit logs. It is also used for many mailing lists set up and used by other people and projects in the FreeBSD community. General lists are lists for the general public, technical lists are mainly for the development of specific areas of interest, and closed lists are for internal communication not intended for the general public. The majority of all the communication in the project goes through these 85 lists , Appendix C.

- Perforce - - Perforce is a commercial software configuration management - system developed by Perforce - Systems that is available on over 50 operating systems. It - is a collection of clients built around the Perforce server - that contains the central file repository and - tracks the operations done upon it. The clients are both - clients for accessing the repository and administration of - its configuration. - - - - -

Pretty Good Privacy Pretty Good Privacy, better known as PGP, is a cryptosystem using a public key architecture to allow people to digitally sign and/or encrypt information in order to ensure secure communication between two parties. A signature is used when sending information out many recipients, enabling them to verify that the information has not been tampered with before they received it. In the FreeBSD Project this is the primary means of ensuring that information has been written by the person who claims to have written it, and not altered in transit.
Secure Shell Secure Shell is a standard for securely logging into a remote system and for executing commands on the remote system. It allows other connections, called tunnels, to be established and protected between the two involved systems. This standard exists in two primary versions, and only version two is used for the FreeBSD Project. The most common implementation of the standard is OpenSSH that is a part of the project's main distribution. Since its source is updated more often than FreeBSD releases, the latest version is also available in the ports tree.
Sub-projects Sub-projects are formed to reduce the amount of communication needed to coordinate the group of developers. When a problem area is sufficiently isolated, most communication would be within the group focusing on the problem, requiring less communication with the groups they communicate with than were the group not isolated.
The Ports Subproject A port is a set of meta-data and patches that are needed to fetch, compile and install correctly an external piece of software on a FreeBSD system. The amount of ports have grown at a tremendous rate, as shown by the following figure.
Number of ports added between 1996 and 2005
is taken from the FreeBSD web site. It shows the number of ports available to FreeBSD in the period 1995 to 2005. It looks like the curve has first grown exponentionally, and then since the middle of 2001 grown linearly. As the external software described by the port often is under continued development, the amount of work required to maintain the ports is already large, and increasing. This has led to the ports part of the FreeBSD project gaining a more empowered structure, and is more and more becoming a sub-project of the FreeBSD project. Ports has its own core team with the as its leader, and this team can appoint committers without FreeBSD Core's approval. Unlike in the FreeBSD Project, where a lot of maintenance frequently is rewarded with a commit bit, the ports sub-project contains many active maintainers that are not committers. Unlike the main project, the ports tree is not branched. Every release of FreeBSD follows the current ports collection and has thus available updated information on where to find programs and how to build them. This, however, means that a port that makes dependencies on the system may need to have variations depending on what version of FreeBSD it runs on. With an unbranched ports repository it is not possible to guarantee that any port will run on anything other than -CURRENT and -STABLE, in particular older, minor releases. There is neither the infrastructure nor volunteer time needed to guarantee this. For efficiency of communication, teams depending on Ports, such as the release engineering team, have their own ports liaisons.
The FreeBSD Documentation Project The FreeBSD Documentation project was started January 1995. From the initial group of a project leader, four team leaders and 16 members, they are now a total of 44 committers. The documentation mailing list has just under 300 members, indicating that there is quite a large community around it. The goal of the Documentation project is to provide good and useful documentation of the FreeBSD project, thus making it easier for new users to get familiar with the system and detailing advanced features for the users. The main tasks in the Documentation project are to work on current projects in the FreeBSD Documentation Set, and translate the documentation to other languages. Like the FreeBSD Project, documentation is split in the same branches. This is done so that there is always an updated version of the documentation for each version. Only documentation errors are corrected in the security branches. Like the ports sub-project, the Documentation project can appoint documentation committers without FreeBSD Core's approval. . The Documentation project has a primer. This is used both to introduce new project members to the standard tools and syntaxes and acts as a reference when working on the project.
