Details Continuing the work from D24586. Original summary: Pass SOURCE_DATE_EPOCH in build environnement if the timestamp is Changes since previous patch:
Currently writing some tooling around Poudriere to verify reproducible builds across the ports tree in an automated way. I've verified the following:
Diff Detail
Event TimelineComment Actions before requesting an exp-run or anything like that, have you tested on a bulk of known problematic ports ? python for example or emacs? Also part of this will only be visible at runtime, like build your python package, install them on a machine, run some python things, just importing the library is enough to trigger the issue (run as root) and check with pkg check if some files have been rebuilt Comment Actions I'll do that now, is there a list of problematic ports already known? I see the history of python and emacs, but if you have a quick list of some others that are widely used, I'll test them now.
Sorry I didn't understand this part. "just importing the library is enough to trigger the issue" -> what issue are you referring to? Comment Actions
Here is a reproducibility test of a random list of ports taken from a typical VPS installation of FreeBSD with a bunch of python, PHP, and other ports. This test ran two builds of all ports, separated by a few seconds, on two different Poudriere jails (with different hostnames).

Comment Actions @bapt any updates on reviewing v2 and the results of the reproducibility test of 160 packages from above? Comment Actions someone needs to understand why the not ok package are not ok, is this is related to the timestamp or not. also some packages needs to be run tested, for example install the python package on a system. As root in a python cli import anything which is installed by the package, and run pkg check to see of this pyc were regenerated. Comment Actions
Here is an updated analysis with a fresh build as of today. I have manually looked into each failing case to determine the reason for the irreproducibility using diffoscope. Please see below and let me know if you want me to send you the diffoscope results.
I can do this run test soon. However, in the interrim, I don't think this run testing blocks the acceptance of this patch. It would be good to make incremental progress towards getting ports to build reproducibly, rather than waiting on the results of verification tests such as the python import test. I do agree that the pyc files might be regenerated at runtime, but in the meantime, can we merge this patch so that we can start publishing weekly/monthly status numbers on the percentage of ports that are reproducible across the Ports collection?

Can we get this merged first (since it would be harmless) so that we can start publishing reproducible builds stats for the Ports collection? The python ports can be looked into after that. Btw, the ports that are root-caused with "(mtimes differ in .pkg-content tar listing)" are due to them not having a distinfo entry, which is a trivial fix. Comment Actions It does as it will break something working today if it does not work. Comment Actions Looks like https://github.com/freebsd/pkg/pull/2577 is needed first after https://github.com/freebsd/pkg/commit/08bf9b3d79b127b127ecf597286ba14c016af8c4 was merged.
I'll do the necessary testing, report back, then file a bugzilla bug to request an exp-run with this patch. Comment Actions
As a good comprehensive example to test: I took the py311-gi-docgen pkg. This python package depends on the following packages: root@rb1:/tmp # pkg info -d py311-gi-docgen py311-gi-docgen-2025.5: python311-3.11.14 py311-typogrify-2.1.0 py311-toml-0.10.2_1 py311-smartypants-2.0.2 py311-pygments-2.19.2 py311-packaging-25.0 py311-markupsafe-3.0.3 py311-markdown-3.10 py311-Jinja2-3.1.6 To test this, I built all of these packages using the patch from this review and this command: doas poudriere testport -NNi -j rb1 textproc/py-gi-docgen I did a before/after test of all the checksums of all installed files by these packages (including their generated .pyc files) with this command: root@rb1:/tmp # pkg info -d py311-gi-docgen | grep -v ':$' | xargs pkg check -s Checking python311-3.11.14: 100% Checking py311-typogrify-2.1.0: 100% Checking py311-toml-0.10.2_1: 100% Checking py311-smartypants-2.0.2: 100% Checking py311-pygments-2.19.2: 100% Checking py311-packaging-25.0: 100% Checking py311-markupsafe-3.0.3: 100% Checking py311-markdown-3.10: 100% Checking py311-Jinja2-3.1.6: 100% I tested the checksums before and after running this command to trigger importing all its dependencies: gi-docgen index Gdk-4.0.gir (using a sample Gdk-4.0.gir file I took from online). To sanity check my findings, I also inserted a space character in a random .py and .pyc file installed by one of its dependencies py311-markdown, then tested with the same checksum command. This was an example output from a .py file with an extra space character: root@rb1:/usr/ports/textproc/py-gi-docgen # pkg check -s py311-markdown Checking py311-markdown: 0% py311-markdown-3.10: checksum mismatch for /usr/local/lib/python3.11/site-packages/markdown/extensions/admonition.py Checking py311-markdown: 100% Is this testing sufficient, since it is mostly generalizable for all python programs like this? I think we are good to do an exp-run of this patch, since the pkg patch has been merged and is out in 2.5.1. I will file a bug for the exp-run request shortly. Comment Actions Could you make it so that lang/python27 + the ports using python27 do not use this feature? Comment Actions Also there is a problem with SOURCE_DATE_EPOCH, try to build a port like filesystems/afuse, filesystems/gphotofs or mail/claws-mail, sysutils/u-boot-tools or net/ipxe Comment Actions
