Noteworthy CVS TagsRELENG_4 (4.X-STABLE), HEAD (-CURRENT)It is required that you use &man.ssh.1; or &man.telnet.1;
with Kerberos 5 to connect to the project hosts and only
&man.ssh.1;, protocol 2 is allowed connecting to the repository
host. These are generally more secure than plain &man.telnet.1; or
&man.rlogin.1; since credential negotiation will always be
encrypted. All traffic is encrypted by default with &man.ssh.1;.
With utilities like &man.ssh-agent.1; and &man.scp.1; also
available, &man.ssh.1; is also far more convenient. If you do
not know anything about &man.ssh.1;, please see
.Commit Bit TypesThe FreeBSD CVS 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 FreeBSD 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 TypeResponsibleTree Componentssrccore@src/, doc/ subject to appropriate reviewdocdoceng@doc/, www/, src/ documentationportsportmgr@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.CVS OperationsIt is assumed that you are already familiar with the basic operation
of CVS.The &a.cvs; are the owners of the CVS repository and
are responsible for direct modification of it for the purposes of
cleanup or fixing some grievous abuse of CVS by a committer.
Should you cause some repository accident, say a bad cvs
import or cvs tag operation, mail the &a.cvs;
(or call one of them) and report the problem to one of them. The only
ones able to directly fiddle the repository bits on the repository hosts
are the repomeisters. To enforce this, there are no login shells
available on the repository machines, except to the repomeisters.The CVS tree is currently split into four distinct repositories,
namely doc, ports,
projects and src. These are
combined under a single CVSROOT when distributed
via CVSup for the convenience of our users.Note that the www module containing sources
for the FreeBSD website is
contained within the doc repository.The CVS repositories are hosted on the repository machines.
Currently, each of the repositories above reside on the same physical
machine, ncvs.FreeBSD.org, but to allow for
the possibility of placing each on a separate machine in the future,
there is a separate hostname for each that committers should use.
Additionally, each repository is stored in a separate directory. The
following table summarises the situation.
&os; CVS Repositories, Hosts and DirectoriesRepositoryHostDirectorydocdcvs.FreeBSD.org/home/dcvsportspcvs.FreeBSD.org/home/pcvsprojectsprojcvs.FreeBSD.org/home/projcvssrcncvs.FreeBSD.org/home/ncvs
CVS operations are done remotely by setting the
CVSROOT environment variable to the appropriate host
and top-level directory (for example,
ncvs.FreeBSD.org:/home/ncvs),
the CVS_RSH variable to ssh, and then
doing the appropriate check-out/check-in operations. Many committers
define aliases which expand to the correct cvs
invocation for the appropriate repository. For example, a &man.tcsh.1;
user may add the following to their .cshrc for this
purpose:alias dcvs env CVS_RSH=ssh cvs -d user@dcvs.freebsd.org:/home/dcvs
alias pcvs env CVS_RSH=ssh cvs -d user@pcvs.freebsd.org:/home/pcvs
alias projcvs env CVS_RSH=ssh cvs -d user@projcvs.freebsd.org:/home/projcvs
alias scvs env CVS_RSH=ssh cvs -d user@ncvs.freebsd.org:/home/ncvsThis way they can do all CVS operations
locally and use Xcvs commit for committing
to the official CVS tree. If you wish to add
something which is wholly new (like contrib-ified
sources, etc), cvs import should be used.
Refer to the &man.cvs.1; manual page for usage.Please do not use
cvs checkout or
update with the official repository machine set
as the CVS Root for keeping your source tree up to date.
Remote CVS is not optimized for network distribution
and requires a big work/administrative overhead on the server side.
Please use our advanced cvsup distribution
method for obtaining the repository bits, and only do the actual
commit operation on the repository host.
We provide an extensive cvsup replication network for this purpose,
as well as give access to cvsup-master if you
really need to stay current to the latest changes.
cvsup-master has got the horsepower to deal with
this, the repository master server does not. &a.kuriyama; is in
charge of cvsup-master.
If you need to use CVS add and
delete operations in a manner that is
effectively a &man.mv.1; operation, then a repository
copy is in order rather than using CVS add and
delete. In a repository copy, a CVS Meister will copy the file(s)
to their new name and/or location and let you know when it is
done. The purpose of a repository copy is to preserve file
change history, or logs. We in the FreeBSD Project greatly
value the change history that CVS gives to the project.CVS reference information, tutorials, and FAQs can be found at:

The information in Karl Fogel's
chapters from Open Source Development with CVS is also very
useful.&a.des; also supplied the following mini primer for
CVS.Check out a module with the co or
checkout command.&prompt.user; cvs checkout shazamThis checks out a copy of the shazam module. If
there is no shazam module in the modules file, it looks for a
top-level directory named shazam instead.
Useful cvs checkout optionsDo not create empty directoriesCheck out a single level, no subdirectoriesCheck out revision, branch or tag
revCheck out the sources as they were on date
date
Practical FreeBSD examples:Check out the miscfs module,
which corresponds to src/sys/miscfs:&prompt.user; cvs co miscfsYou now have a directory named miscfs
with subdirectories CVS,
deadfs, devfs, and so
on. One of these (linprocfs) is
empty.Check out the same files, but with full path:&prompt.user; cvs co src/sys/miscfsYou now have a directory named src,
with subdirectories CVS and
sys. The src/sys directory has
subdirectories CVS and
miscfs, etc.Check out the same files, but prunes empty
directories:&prompt.user; cvs co -P miscfsYou now have a directory named
miscfs with subdirectories
CVS, deadfs,
devfs... but note that there is no
linprocfs subdirectory, because there
are no files in it.Check out the directory miscfs, but
none of the subdirectories:&prompt.user; cvs co -l miscfsYou now have a directory named miscfs
with just one subdirectory named
CVS.Check out the miscfs module as
it is in the 4.X branch:&prompt.user; cvs co -rRELENG_4 miscfsYou can modify the sources and commit along this
branch.Check out the miscfs module as
it was in 3.4-RELEASE.&prompt.user; cvs co -rRELENG_3_4_0_RELEASE miscfsYou will not be able to commit modifications, since
RELENG_3_4_0_RELEASE is a point in time, not a branch.Check out the miscfs module as it was
on Jan 15 2000.&prompt.user; cvs co -D'01/15/2000' miscfsYou will not be able to commit modifications.Check out the miscfs module as it was
one week ago.&prompt.user; cvs co -D'last week' miscfsYou will not be able to commit modifications.Note that cvs stores metadata in subdirectories named
CVS.Arguments to and
are sticky, which means cvs will remember them later, e.g.
when you do a cvs update.Check the status of checked-out files with the
status command.&prompt.user; cvs status shazamThis displays the status of the
file shazam or of every file in the
shazam directory. For every file, the
status is given as one of:Up-to-dateFile is up-to-date and unmodified.Needs PatchFile is unmodified, but there is a newer revision in
the repository.Locally ModifiedFile is up-to-date, but modified.Needs MergeFile is modified, and there is a newer revision in the
repository.File had conflicts on mergeThere were conflicts the last time this file was
updated, and they have not been resolved yet.You will also see the local revision and date,
the revision number of the newest applicable version
(newest applicable because if you have a
sticky date, tag or branch, it may not be the actual newest
revision), and any sticky tags, dates or options.Once you have checked something out, you can update it with the
update command.&prompt.user; cvs update shazamThis updates the file shazam or the
contents of the shazam directory to the
latest version along the branch you checked out. If you
checked out a point in time, does nothing
unless the tags have moved in the repository or some other weird
stuff is going on.Useful options, in addition to those listed above for
checkout:Check out any additional missing directories.Update to head of main branch.More magic (see below).If you checked out a module with or
, running cvs update
with a different or
argument or with will select a new branch,
revision or date. The option clears all
sticky tags, dates or revisions whereas
and set new ones.Theoretically, specifying HEAD as the
argument to will give you the same result
as , but that is just theory.The option is useful if:somebody has added subdirectories to the module
you have checked out after you checked it out.you checked out with , and later
change your mind and want to check out the subdirectories
as well.you deleted some subdirectories and want to check
them all back out.Watch the output of the cvs
update with care. The letter in front of
each filename indicates what was done with it:UThe file was updated without trouble.PThe file was updated without trouble (you will only see
this when working against a remote repository).MThe file had been modified, and was merged without
conflicts.CThe file had been modified, and was merged with
conflicts.Merging is what happens if you check out a copy of
some source code, modify it, then someone else commits a
change, and you run cvs update. CVS notices
that you have made local changes, and tries to merge your
changes with the changes between the version you originally
checked out and the one you updated to. If the changes are to
separate portions of the file, it will almost always work fine
(though the result might not be syntactically or semantically
correct).CVS will print an M in front of every locally modified
file even if there is no newer version in the repository, so
cvs update is handy for getting a summary
of what you have changed locally.If you get a C, then your changes
conflicted with the changes in the repository (the changes
were to the same lines, or neighboring lines, or you changed
the local file so much that cvs can not
figure out how to apply the repository's changes). You will have
to go through the file manually and resolve the conflicts;
they will be marked with rows of <,
= and > signs. For
every conflict, there will be a marker line with seven
< signs and the name of the file,
followed by a chunk of what your local file contained,
followed by a separator line with seven =
signs, followed by the corresponding chunk in the
repository version, followed by a marker line with seven
> signs and the revision number you
updated to.The option is slightly voodoo. It
updates the local file to the specified revision as if you
used , but it does not change the recorded
revision number or branch of the local file. It is not really
useful except when used twice, in which case it will merge the
changes between the two specified versions into the working
copy.For instance, say you commit a change to
shazam/shazam.c in &os.current; and later
want to MFC it. The change you want to MFC was revision
1.15:Check out the &os.stable; version of the
shazam module:&prompt.user; cvs co -rRELENG_4 shazamApply the changes between rev 1.14 and 1.15:&prompt.user; cvs update -j1.14 -j1.15 shazam/shazam.cYou will almost certainly get a conflict because
- of the $Id: article.sgml,v 1.180 2004-02-27 15:23:15 ale Exp $ (or in FreeBSD's case,
+ of the $Id: article.sgml,v 1.181 2004-04-01 19:43:15 hrs Exp $ (or in FreeBSD's case,
$FreeBSD$)
lines, so you will have to edit the file to resolve the conflict
- (remove the marker lines and the second $Id: article.sgml,v 1.180 2004-02-27 15:23:15 ale Exp $ line,
- leaving the original $Id: article.sgml,v 1.180 2004-02-27 15:23:15 ale Exp $ line intact).
+ (remove the marker lines and the second $Id: article.sgml,v 1.181 2004-04-01 19:43:15 hrs Exp $ line,
+ leaving the original $Id: article.sgml,v 1.181 2004-04-01 19:43:15 hrs Exp $ line intact).
View differences between the local version and the
repository version with the diff
command.&prompt.user; cvs diff shazamshows you every modification you have made to the
shazam file or module.
Useful cvs diff optionsUses the unified diff format.Uses the context diff format.Shows missing or added files.
You always want to use , since
unified diffs are much easier to read than almost any other
diff format (in some circumstances, context diffs generated with
the option may be
better, but they are much bulkier). A unified diff consists of
a series of hunks. Each hunk begins with a line that starts
with two @ signs and specifies where in the
file the differences are and how many lines they span. This
is followed by a number of lines; some (preceded by a blank)
are context; some (preceded by a - sign)
are outtakes and some (preceded by a +) are
additions.You can also diff against a different version
than the one you checked out by specifying a version
with or as in
checkout or update,
or even view the diffs between two arbitrary versions
(without regard for what you have locally) by specifying
two versions with or
.View log entries with the log
command.&prompt.user; cvs log shazamIf shazam is a file, this will print a
header with information about this file, such
as where in the repository this file is stored, which revision is
the HEAD for this file, what branches this file
is in, and any tags that are valid for this file. Then, for each
revision of this file, a log message is printed. This includes
the date and time of the commit, who did the commit, how many lines
were added and/or deleted, and finally the log message that the
committer who did the change wrote.If shazam is a directory, then the log
information described above is printed for each file in the
directory in turn. Unless you give the to
log, the log for all subdirectories of
shazam is printed too, in a recursive
manner.Use the log command to view the history of
one or more files, as it is stored in the CVS repository. You can
even use it to view the log message of a specific revision, if you
add the to the
log command:&prompt.user; cvs log -r1.2 shazamThis will print only the log message for revision
1.2 of file shazam if it is
a file, or the log message for revision 1.2 of
each file under shazam if it is a
directory.See who did what with the annotate command.
This command shows you each line of the specified file or
files, along with which user most recently changed that
line.&prompt.user; cvs annotate shazamAdd new files with the add command.Create the file, cvs add it, then
cvs commit it.Similarly, you can add new directories by creating them
and then cvs adding them. Note that you
do not need to commit directories.Remove obsolete files with the remove command.Remove the file, then cvs rm it, then
cvs commit it.Commit with the commit or
checkin command.
Useful cvs commit optionsForce a commit of an unmodified file.Specify a commit message on the command line rather
than invoking an editor.
Use the option if you realize that
you left out important information from the commit message.Good commit messages are important. They tell others
why you did the changes you did, not just right here and now,
but months or years from now when someone wonders why some
seemingly illogical or inefficient piece of code snuck into
your source file. It is also an invaluable aid to deciding
which changes to MFC and which not to MFC.Commit messages should be clear, concise and provide
a reasonable summary to give an indication of what was
changed and why.Commit messages should provide enough information to
enable a third party to decide if the change is relevant to
them and if they need to read the change itself.Avoid committing several unrelated changes in one go. It
makes merging difficult, and also makes it harder to determine
which change is the culprit if a bug crops up.Avoid committing style or whitespace fixes and
functionality fixes in one go. It makes merging difficult,
and also makes it harder to understand just what functional
changes were made. In the case of documentation files, it
can make the job of the translation teams more complicated,
as it becomes difficult for them to determine exactly what
content changes need to be translated.Avoid committing changes to multiple files in one go
with a generic, vague message. Instead, commit each file (or
small, related groups of files) with tailored commit messages.Before committing, always:verify which branch you are committing to, using
cvs status.review your diffs, using
cvs diffAlso, ALWAYS specify which files to commit explicitly on
the command line, so you do not accidentally commit other files
than the ones you intended - cvs commit
without any arguments will commit every modification in your
current working directory and every subdirectory.Additional tips and tricks:You can place commonly used options in your
~/.cvsrc, like this:cvs -z3
diff -Nu
update -Pd
checkout -PThis example says:always use compression level 3 when talking to a
remote server. This is a life-saver when working over a
slow connection.always use the (show added or
removed files) and (unified diff
format) options to &man.diff.1;.always use the (prune empty
directories) and (check out new
directories) options when updating.always use the (prune empty
directories) option when checking out.Use Eivind Eklund's cdiff script to
view unidiffs. It is a wrapper for &man.less.1; that adds ANSI
color codes to make hunk headers, outtakes and additions stand
out; context and garbage are unmodified. It also expands tabs
properly (tabs often look wrong in diffs because of the extra
character in front of each line).Simply use it instead of &man.more.1; or &man.less.1;:&prompt.user; cvs diff -Nu shazam | cdiffAlternatively some editors like &man.vim.1;
(editors/vim5) have color support and when used as
a pager with color syntax highlighting switched on will
highlight many types of file, including diffs, patches,
and CVS/RCS logs. &prompt.user; echo "syn on" >> ~/.vimrc
&prompt.user; cvs diff -Nu shazam | vim -
&prompt.user; cvs log shazam | vim -CVS is old, arcane, crufty and buggy, and sometimes
exhibits non-deterministic behavior which some claim as proof
that it is actually merely the Newtonian manifestation of a
sentient transdimensional entity. It is not humanly possible
to know its every quirk inside out, so do not be afraid to ask
the resident AI (&a.cvs;) for help.Do not leave the cvs commit command in commit
message editing mode for too long (more than 2–3 minutes). It
locks the directory you are working with and will prevent other
developers from committing into the same directory. If you have
to type a long commit message, type it before executing
cvs commit, and insert it into the commit
message.Conventions and TraditionsAs a new committer there are a number of things you should do
first.Add yourself to the Developers section of
the Contributors List
and remove yourself from the Additional
Contributors section. Once you have done that, do not
forget to add your author entity to
doc/en_US.ISO8859-1/share/sgml/authors.ent;
use the other entries as example.This is a relatively easy task, but remains a good first test of
your CVS skills.Add an entry for yourself to
www/en/news/news.xml. Look for the other
entries that look like A new committer and follow the
format.You should add your PGP or GnuPG key to
doc/share/pgpkeys (and if you do not
have a key, you should create one).&a.des; has
written a shell script to make this extremely simple. See the
README
file for more information.It is important to have an up-to-date PGP/GnuPG key in
the Handbook, since the key may be required for positive
identification of a committer, e.g. by the &a.admins; for
account recovery.Some people add an entry for themselves to
ports/astro/xearth/files/freebsd.committers.markers.Some people add an entry for themselves to
src/usr.bin/calendar/calendars/calendar.freebsd.Introduce yourself to the other committers, otherwise no one
will have any idea who you are or what you are working on. You do
not have to write a comprehensive biography, just write a paragraph
or two about who you are and what you plan to be working on as a
committer in FreeBSD. Email this to the &a.developers; and you will
be on your way!Log into hub.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
hub often get accidentally truncated
without warning, so forward it or read it and you will not lose
it.If you are subscribed to the &a.cvsall;, you will
probably want to unsubscribe to avoid receiving duplicate
copies of commit messages and their followups.All new committers also have a mentor assigned to them for
the first few months. Your mentor is more or less responsible for
explaining anything which is confusing to you and is also
responsible for your actions during this initial period. If you
make a bogus commit, it is only going to embarrass your mentor
and you should probably make it a policy to pass at least your
first few commits by your mentor before committing it to the
repository.All commits should go to &os.current; first
before being merged to &os.stable;. No major new
features or high-risk modifications should be made to the
&os.stable; branch.Developer RelationsIf you are 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. If you see 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. If, however, you are
about to modify something which is clearly being actively
maintained by someone else (and it is only by watching the
cvs-committers mailing list that you can
really get a feel for just what is and is not) then consider
sending the change to them instead, just as you would have
before becoming a committer. For ports, you should contact the
listed MAINTAINER in the
Makefile. For other parts of the
repository, if you are unsure who the active maintainer might
be, it may help to scan the output of cvs log
to see who has committed changes in the past. &a.fenner; has
written a nice shell script that can help determine who the
active maintainer might be. It lists each person who has
committed to a given file along with the number of commits each
person has made. It can be found on freefall
at ~fenner/bin/whodid. If your queries go
unanswered or the committer otherwise indicates a lack of
proprietary interest in the area affected, go ahead and commit
it.If you are unsure 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 CVS repository. If you do
happen to commit something which results in controversy
erupting, you may also wish to consider backing the change out
again until the matter is settled. Remember – with CVS we
can always change it back.Do not impugn the intentions of someone you disagree with.
If they see a different solution to a problem than you, or even
a different problem, it is not because they are stupid, because
they have questionable parentage, or because they are trying to
destroy your hard work, personal image, or FreeBSD, but simply
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.GNATSThe FreeBSD Project utilizes
GNATS for tracking bugs and change
requests. Be sure that if you commit a fix or suggestion found
in a GNATS PR, you use
edit-pr pr-number
on freefall to close it. It is also considered
nice if you take time to close any PRs associated with your
commits, if appropriate. You can also make use of
&man.send-pr.1; yourself for proposing any change which you feel
should probably be made, pending a more extensive peer-review
first.You can find out more about GNATS
at:http://www.FreeBSD.org/support.html&man.send-pr.1;You can run a local copy of GNATS, and then integrate the FreeBSD
GNATS tree in to it using CVSup. Then you can run GNATS commands
locally, or use other interfaces, such as tkgnats.
This lets you query the PR database without needing to be connected to
the Internet.Using a local GNATS treeIf you are not already downloading the GNATS tree, add this line
to your supfile, and re-sup. Note that since
GNATS is not under CVS control it has no tag, so if you are adding
it to your existing supfile it should appear
before any tag= entry as these remain active once set.
gnats release=current prefix=/usrThis will place the FreeBSD GNATS tree in
/usr/gnats. You can use a
refuse file to control which categories to
receive. For example, to only receive docs PRs,
put this line in
/usr/local/etc/cvsup/sup/refuseThe precise path depends on the *default
base setting in your
supfile..gnats/[a-ce-z]*The rest of these examples assume you have only supped the
docs category. Adjust them as necessary,
depending on the categories you are syncing.Install the GNATS port from
ports/databases/gnats. This will place the
various GNATS directories under
$PREFIX/share/gnats.Symlink the GNATS directories you are supping under the version
of GNATS you have installed.&prompt.root; cd /usr/local/share/gnats/gnats-db
&prompt.root; ln -s /usr/gnats/docsRepeat as necessary, depending on how many GNATS categories you
are syncing.Update the GNATS categories file with these
categories. The file is
$PREFIX/share/gnats/gnats-db/gnats-adm/categories.# This category is mandatory
pending:Category for faulty PRs:gnats-admin:
#
# FreeBSD categories
#
docs:Documentation Bug:freebsd-doc:Run $PREFIX/libexec/gnats/gen-index to
recreate the GNATS index. The output has to be redirected to
$PREFIX/share/gnats/gnats-db/gnats-adm/index.
You can do this periodically from &man.cron.8;, or run &man.cvsup.1;
from a shell script that does this as well.&prompt.root; /usr/local/libexec/gnats/gen-index \
> /usr/local/share/gnats/gnats-db/gnats-adm/indexTest the configuration by querying the PR database. This
command shows open docs PRs.&prompt.root; query-pr -c docs -s openOther interfaces, such as that provided by the
databases/tkgnats port should also work

meisters, there are other FreeBSD 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.jhb;John is the manager of the SMPng Project, and has
authority over the architectural design and implementation
of the move to fine-grained kernel threading and locking.
He's also the editor of the SMPng Architecture Document.

infrastructure, approving new documentation committers, and
ensuring that the FreeBSD website and documentation on the FTP
site is up to date with respect to the CVS tree. It is not a
conflict resolution body. The vast majority of documentation
related discussion takes place on the &a.doc;. Committers
interested in contributing to the documentation should familiarize
themselves with the Documentation Project

time), these are the people to talk to about it.Bruce is also the keeper of the release documentation
(src/release/doc/*). If you commit a

commit messages. You should never send email
directly to this list. You should 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. This list is
not intended as a place for code reviews or a
replacement for the &a.arch; or the &a.audit;. In fact
using it as such hurts the FreeBSD Project as it gives a sense of a
closed list where general decisions affecting all of the FreeBSD
using community are made without being open.
Last, but not least never, never ever, email
the &a.developers; and CC:/BCC: another FreeBSD list.
Never, ever email another FreeBSD email list and CC:/BCC:
the &a.developers;. Doing so can greatly diminish the benefits
of this list. Also, never publicly post or forward emails sent
to the &a.developers;. The act of sending to
the &a.developers; vs. a public list means the information in
the email is not for public consumption.
SSH Quick-Start GuideIf you are using FreeBSD 4.0 or later,
OpenSSH is included in the base system.
If you are using an earlier release,
update and install one of the SSH ports. In general,
you will probably want to get OpenSSH from the
security/openssh port. You
may also wish to check out the original ssh1 in the
security/ssh port, but make
certain you pay attention to its license. Note that both
of these ports cannot be installed at the same time.If you do not wish to type your password in every
time you use &man.ssh.1;, and you use RSA or DSA 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 file. See &man.ssh-agent.1;
for details.Generate a key pair using &man.ssh-keygen.1;. The key
pair will wind up in your
$HOME/.ssh/
directory.Send your public key
($HOME/.ssh/id_dsa.pub
or $HOME/.ssh/id_rsa.pub)
to the person setting you up as a committer so it can be put
into yourlogin file in
/c/ssh-keys/ on
freefall.
Now you should be able to use &man.ssh-add.1; for
authentication once per session. This will prompt you for
your private key's pass phrase, and then store it in your
authentication agent (&man.ssh-agent.1;). If you no longer
wish to have your key stored in the agent, issuing
ssh-add -d will remove it.Test by doing something such as 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;.The FreeBSD Committers' Big List of RulesRespect other committers.Respect other contributors.Discuss any significant change
before committing.Respect existing maintainers (if listed in the
MAINTAINER field in
Makefile or in the
MAINTAINER file 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. If you must strongly disagree about
something, do so only in private.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, and
src/sys/contrib trees without
explicit approval from the respective
maintainer(s).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.DetailsRespect 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 person(s) 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 CVS repository is not where changes should be
initially submitted for correctness or argued over, that
should happen first in the mailing lists and the commit should
only happen once something resembling consensus has
been reached. This does not mean that you have to ask
permission before correcting every obvious syntax error or
manual page misspelling, simply that you should try 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
you are on the right track is to have your code reviewed by
one or more other committers.When in doubt, ask for review!Respect existing maintainers if listed.Many parts of FreeBSD 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
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,
you can also look at the CVS logs for the file(s) in
question and see if someone has been working recently or
predominantly in that area.Other areas of FreeBSD fall under the control of
someone who manages an overall category of FreeBSD
evolution, such as internationalization or networking.
See
http://www.FreeBSD.org/doc/en_US.ISO8859-1/articles/contributors/staff-who.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 CVS 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 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_4_5) 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. If you must strongly disagree about
something, do so only in private.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. That
means that you should not air your angry words in public
and you should not forward private correspondence to
public mailing lists or aliases. 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 you 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 3rd party
to resolve the dispute. All parties involved must then
agree to be bound by the decision reached by this 3rd
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
FreeBSD 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. Currently, this is only the x86
and the Alpha so it is pretty easy to do. If you need to
test on the AXP, your account on beast.FreeBSD.org will let you
compile and test Alpha binaries/kernels/etc. As other
architectures are added to the FreeBSD 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
maintainer(s).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, you should submit your patches to
the vendor. If your changes are FreeBSD-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 ArchitecturesFreeBSD has added several new arch ports during the 5.0
release cycle and is truly no longer an &i386; centric operating
system. In an effort to make it easier to keep FreeBSD portable
across the platforms we support, core has developed the following
mandate:
Our 32 bit reference platform is i386, and our 64 bit
reference platform is Sparc64. 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 i386 and Sparc64 platforms were chosen due to being more
readily available to developers and as representatives of more
diverse processor and system designs - big vs little endian,
register file vs register stack, different DMA and cache
implementations, hardware page tables vs software TLB management
etc.While the Alpha is a 64 bit processor, it is a more
traditional processor design and does not provide as good a testbed
for many of the challenges that the other 64 bit platform ports
face. The ia64 platform has many of the same complications that
Sparc64 has, but is still limited in availability to
developers.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 SuggestionsWhen committing documentation changes, use a spell checker
before committing. For all SGML docs, you should also
verify that your formatting directives are correct by running
make lint.For all on-line manual pages, run manck
(from ports) 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 using cvs diff, which can hide
any new bugs. Do not include whitespace changes with content
changes in commits to doc/ or
www/. 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 FeaturesWhen it is necessary to remove functionality from software
in the base system the following guidelines should be followed
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.Support for Multiple ArchitecturesFreeBSD 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
FreeBSD 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 FreeBSD "target audience".
Statement of General IntentThe FreeBSD 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 FreeBSD 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 FreeBSD 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 FreeBSD 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 ArchitecturesTier 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 tinderbox support either in the FreeBSD.org cluster, or
easily available for all developers.Tier 1 architectures are expected to be Production Quality
with respects to all aspects of the FreeBSD operating system,
including installation and development environments.Current Tier 1 platforms are i386, Sparc64, AMD64, PC98,
and Alpha.Tier 2: Developmental ArchitecturesTier 2 platforms are not supported by the security officer
and release engineering teams. At the discretion of the
toolchain maintainer, they may be supported in the toolchain. New
features added to FreeBSD should be feasible to implement on these
platforms, but an implementation is not required before the
feature may be added to the FreeBSD source tree. The
implementation of a Tier 2 architecture may be committed to the
main FreeBSD 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
FreeBSD base source tree, the platform must be able to boot to at
least single-user mode on real world commodity hardware. Some
exceptions to these rules may be made for new hardware that is
under development by hardware vendors, but not yet available to
the project.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.Current Tier 2 platforms are PowerPC and ia64.Tier 3: Experimental ArchitecturesTier 3 platforms are not supported by the security officer
and release engineering teams. At the discretion of the toolchain
maintainer, they may be supported in the toolchain. Tier 3
platforms are architectures for which hardware is not or will not
be available to the project in the foreseeable future, for which
there are two or fewer active developers, that can not boot to at
least single-user mode on real hardware (or a simulator for new
hardware platforms), or which are considered legacy systems
unlikely to see broad future use. Tier 3 systems will not be
committed to the base source tree, although support for Tier 3
systems may be worked on in the FreeBSD Perforce Repository,
providing source control and easier change integration from the
main FreeBSD tree.Current Tier 3 platforms are &s390;.Tier 4: Unsupported ArchitecturesTier 4 systems are not supported in any form by the project.
All systems not otherwise classified into a support tier
are Tier 4 systems.Policy on Changing the Tier of an ArchitectureSystems may only be moved from one tier to another by
approval of the FreeBSD Core Team, which shall make that
decision in collaboration with the Security Officer, Release
Engineering, and toolchain maintenance teams.Ports Specific FAQAdding a New PortHow do I add a new port?First, please read the section about repository
copies.The easiest way to add a new port is to use the
addport script on
freefall. It will add a port from the
directory you specify, determining the category automatically
from the port Makefile.
It will also add an entry to the
CVSROOT/modules file and the port's
category Makefile. It was
written by &a.mharo; and &a.will;, but Will is the current
maintainer so please send questions/patches about
addport to him.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 packageThe
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 FreeBSD Contributors
List.Close the PR if the port came in as a PR. To close
a PR, just do
edit-pr PR#
on freefall and change the
state from open
to closed. You will be asked to
enter a log message and then you are done.Repository CopiesWhen 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 you want to change the
name of a directory because the author(s) renamed their
software even though it is a
descendant of a port already in a tree.When do we not need a
repository copy?When there is no history to preserve. If a port is
added into a wrong category and is moved immediately,
it suffices to simply cvs remove the
old one and addport the new
one.What do I need to do?File a PR in GNATS, listing the
reasons for the repository copy request. Assign it to
portmgr and set state to
repocopy. If &a.portmgr; approves it,
it will be reassigned to cvs. &a.cvs; will
do a repository copy from the old to the new location, and
reassign the PR back to you. Once everything is done, perform the
following:When a port has been repo copied:Upgrade the copied port to the new version (remember
to change the PORTNAME so there
are not duplicate ports with the same name).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 accordinglyAdd the new module entry.Add an entry to
ports/MOVED.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, the old
SUBDIR entry and the old module
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 FreezeWhat is a ports freeze?Before a release, it is necessary to restrict
commits to the ports tree for a short period of time
while the packages and the release itself are being
built. This is to ensure consistency among the various
parts of the release, and is called the ports
freeze.How long is a ports freeze?Usually an hour or two.What does it mean to me?During the ports freeze, you are not allowed to
commit anything to the tree without explicit approval
from the ports manager. Explicit
approval here means either of the
following:You asked the ports manager and got a reply
saying, Go ahead and commit
it.The ports manager sent a mail to you or the
mailing lists during the ports freeze pointing out
that the port is broken and has to be fixed.Note that you do not have implicit permission to fix
a port during the freeze just because it is
broken.How do I know when the ports freeze starts?The ports manager will send out warning messages to
the &a.ports; and &a.committers;
announcing the start of the impending release, usually
two or three weeks in advance. The exact starting time
will not be determined until a few days before the
actual release. This is because the ports freeze has to
be synchronized with the release, and it is usually not
known until then when exactly the release will be
rolled.When the freeze starts, there will be another
announcement to the &a.committers;, of course.How do I know when the ports freeze ends?A few hours after the release, the ports manager
will send out a mail to the &a.ports; and &a.committers;
announcing the end of the ports freeze. Note that the
release being cut does not automatically end the freeze.
We have to make sure there will not be any last minute
snafus that result in an immediate re-rolling of the
release.Miscellaneous QuestionsHow do I know if my port is building correctly or
not?First, go check
.
There you will find error logs from the latest package
building runs on all supported platforms for the most
recent branches.However, just because the port does not show up there
does not mean it is building correctly. (One of the
dependencies may have failed, for instance.) Here are
the relevant directories on bento, so feel free to dig
around. /a/asami/portbuild/<arch>/<major_version>/errors error logs from latest <major_version> run on <arch>
/logs all logs from latest <major_version> run on <arch>
/packages packages from latest <major_version> run on <arch>
/bak/errors error logs from last complete <major_version> run on <arch>
/bak/logs all logs from last complete <major_version> run on <arch>
/bak/packages packages from last complete <major_version> run on <arch>
Basically, if the port shows up in
packages, or it is in
logs but not in
errors, it built fine. (The
errors directories are what you get
from the web page.)I added a new port. Do I need to add it to the
INDEX?No. The ports manager will regenerate the
INDEX and commit it every few
days.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
ports manager is very protective of
ports/Mk/bsd.port*.mk so do not
commit changes to those files unless you want to face his
wra(i)th.What is the proper procedure for updating the checksum
for a port's distfile when the file changes without a
version change?When the checksum for a port's distfile is updated due
to the author updating the file without changing the port's
revision, the commit message should include 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.Perks of the JobUnfortunately, there are not many perks involved with being a
committer. Recognition as a competent software engineer is probably
the only thing that will be of benefit in the long run. However,
there are at least some perks:Direct access to cvsup-masterAs a committer, you may apply to &a.kuriyama; for direct access
to cvsup-master.FreeBSD.org,
providing the public key output from cvpasswd
yourusername@FreeBSD.org
freefall.FreeBSD.org. Please note: you must
specify freefall.FreeBSD.org on the
cvpasswd command line even though the
actual server is cvsup-master. Access to
cvsup-master should not be overused as it is
a busy machine.A Free 4-CD Set or DVD SubscriptionFreeBSD Mall,
Inc. offers a free subscription of the 4-CD set or
the DVD product to all FreeBSD committers. Information about how
to obtain your free media is mailed to
developers@FreeBSD.org following each major
release.Miscellaneous QuestionsWhy are trivial or cosmetic changes to files on a vendor
branch a bad idea?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.The option does not work very well.
Ask &a.obrien; for horror stories.How do I add a new file to a CVS 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
cvs add as you normally would. For
example, if you wanted to MFC the file
src/sys/alpha/include/smp.h from HEAD
to RELENG_4 and it does not exist in RELENG_4 yet, you would
use the following steps:MFC'ing a New File&prompt.user; cd sys/alpha/include
&prompt.user; cvs update -rRELENG_4
cvs update: Updating .
U clockvar.h
U console.h
...
&prompt.user; cvs update -kk -Ap smp.h > smp.h
===================================================================
Checking out smp.h
RCS: /usr/cvs/src/sys/alpha/include/smp.h,v
VERS: 1.1
***************
&prompt.user; cvs add smp.h
cvs add: scheduling file `smp.h' for addition on branch `RELENG_4'
cvs add: use 'cvs commit' to add this file permanently
&prompt.user; cvs commitWhat meta information should I include in a
commit message?As well as including an informative message with each commit
you may need to include some additional information as
well.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.Submitted by:The name and e-mail address of the person that
submitted the fix; for committers, just the username on
the FreeBSD cluster.Reviewed by:The name and e-mail address of the person or people
that reviewed the change; for committers, just the
username on the FreeBSD 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 committers, just the
username on the FreeBSD 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. If these are your first commits then
you should have passed them past your mentor first, and
you should list your mentor, as in
``username-of-mentor(mentor)''.
Obtained from:The name of the project (if any) from which the code
was obtained.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.Commit log for a commit based on a PRYou want to commit a change based on a PR submitted by John
Smith containing a patch. The end of the commit message should
look something like this....
PR: foo/12345
Submitted by: John Smith <John.Smith@example.com>Commit log for a commit needing reviewYou want to change the virtual memory system. You have
posted patches to the appropriate mailing list (in this case,
freebsd-arch) and the changes have been

commit to &os.stable; to follow at a later date.You want to commit some code which will be merged from
&os.current; into the &os.stable; branch after two
weeks....
MFC after: 2 weeksWhere 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,
or may be left off (in which case, days will be assumed).In some cases you may need to combine some of these.Consider the situation where a user has submitted a PR
containing code from the NetBSD project. You are looking at the
PR, but it is not an area of the tree you normally work in, so
you have decided to get the change reviewed by the
arch mailing list. Since the change is
complex, you opt to MFC after one month to
allow adequate testing.The extra information to include in the commit would look
something likePR: foo/54321

or project information?people.FreeBSD.org is the
same as freefall.FreeBSD.org. Just create a
public_html directory. Anything you

under .Where are the mailing list archives stored?The mailing lists are archived under /g/mail
which will show up as /hub/g/mail with &man.pwd.1;.
