Event Timeline
@infrandomness Nicely suggested using one of their machines running FreeBSD. We've set up a BuildKite agent and this patch should allow targeting the agent in our CI.
We are aware that some tests are failing on FreeBSD, and it would be nice if the FreeBSD maintainers could take a look. Also, it would be nice to add at least one other FreeBSD runner that is not backed by an individual to ensure that our CI setup is robust. If @infrandomness can't provide the machine anymore in the future, or even if they simply have a power outage, it would be nice for our CI setup to still work. But this is an excellent start!
@infrandomness thanks a lot for providing this CI runner!
I had a look at the failed tests and it seems the number isn't too large and most of them seem to be filesystem and locales.
Two areas where I'm not surprised that there are issues.
@ldionne Do we want to add XFAIL to the failing tests or add a soft_fail entry?
I have some WIP patches for the locale tests that I should update . I'm not sure how long it will take to fix all the tests so maybe xfail is better so that regressions are caught?
It would be great when you can fix these tests! We can indeed make them XFAIL now and remove that in patches that fixes the tests.
We do the same for AIX, they have some people submitting fixes for their failing locale tests.
Add a bunch of XFAILs for tests failing on FreeBSD. Let's try to keep those temporary.
Ping, LLVM 15 is branching soon and it would be awesome to have some confidence on our FreeBSD support.
Ping.
This situation is exactly why we have the support policy that we have: we are interested in supporting platforms that want to be supported, i.e. that want to invest the time required to make things work. People have volunteered machines to test on FreeBSD, and have volunteered time to get this patch up. All it needs is someone (probably someone who cares first hand about FreeBSD support) to finish it up and start fixing the LIBCXX-FREEBSD-FIXMEs added here.
I would be happy to address these FIXMEs, but I would have to do so outside working hours so my time is somewhat limited. I recently ran the testsuite on my Arm Morello system running CheriBSD and it seems like a lot of the filesystem ones are fixed on this FreeBSD 14 snapshot.
Which version of FreeBSD is the builder running? This would allow me to reproduce and attach a debugger on a similar system.

Buildkite is running on my test worker configured with the token I've been provided. Looking to see what else needs to be configured
With what invocation are you running the buildkite agent? Looking at our Dockerfile you probably have to do something like echo "tags=\"queue=libcxx-builders,arch=$(uname -m),os=freebsd\"" >> "/home/libcxx-builder/.buildkite-agent/buildkite-agent.cfg". (FYI for these kinds of questions the libc++ Discord channel might be easier)
tags were not set correctly; I'll see about submitting a patch to update AddingNewCIJobs.rst with a sample buildkite-agent.cfg snippet.
Next up, it seems that I need to iterate on installing the right packages. Is there an easy way to rerun a failed job?

| 257 ↗ | (On Diff #440185) | The intent of this one is to tag specifically those XFAILs added as part of enabling CI? There is one case of XFAIL: freebsd in the tree now (trivial_copy_move_ABI.pass.cpp). |
| libcxx/utils/libcxx/test/features.py | ||
|---|---|---|
| 257 ↗ | (On Diff #440185) | Yeah, this is just that the test fails for some reason. IOW they should be worked through after this patch is landed and checked whether to convert the XFAIL: LIBCXX-FREEBSD-FIXME to an XFAIL: freebsd if the failure is expected/wanted, or fix the test/library that is broken. Looking at the list, std::filesystem probably just isn't implemented on FreeBSD and the locale tests will have to be modified because it's the least portable portable interface ever. |
With the XFAILS from this review added I'm seeing Failed Tests (494)
Many of these are compile failures while building the test code, e.g.

I'll iterate on adjusting XFAILs before submitting a final version of this change
@emaste which compiler are you using? If it's /usr/bin/clang++ that is too old I believe and would explain those test failures.
Looking at the CI logs, clang 13 seems to be used, which is indeed too old. You have to upgrade to at least 14, 15 recommended for better test coverage.

|---|---|---|

Forcing CI to use clang15 for now and have the following failures:

Looking much better, one or two more iterations on XFAILs and should be good to go.
With remaining failing tests marked with XFAIL we report no failures, although the test still returns error:

Do the unexpected passes cause the run to fail?
With that addressed failure is now

I had a look and there are two issues
- check-cxx-abilist requires and ABI list to be available. This can be generated with building the target generate-cxx-abilist. This should generate an abilist that should be included in libc++.
- the target generate-cxx-abilist fails

As my next step I'll curate the patches and hacks and submit individual reviews for those changes.

Update & rebase after committing a number of related changes, and limit this review to the CI portion only
- XFAIL adjustments are in D141542
- I've temporarily removed the clang-tidy bits in my local tree as there is an issue that needs to be investigated/resolved
- A number of tests either had inconsistent results or timeouts and I have excluded them temporarily
- atomic_wait.pass.cpp
- atomic_wait_explicit.pass.cpp
- atomic_notify_one.pass.cpp
- thread.lock.shared.locking/lock.pass.cpp
Everything should be ready now, test run in progress at https://buildkite.com/llvm-project/libcxx-ci/builds/17740
Thanks a lot for working on this, LGTM!
I don't have approval rights, for the ABI group, @ldionne, can you approve that?
Before you land this, can you make sure you rebase and give the CI another test run?
I've been using D140050 as a scratch-pad to iterate on testing (in an attempt to avoid spamming everyone on the subscriber list here) and will keep it updated regularly until this lands. I did submit many runs with an additional change that removed the other, non-FreeBSD CI targets to speed iteration and avoid unnecessary CI cycles.
Once this is in I will have to keep an eye on the load on the CI runner to make sure it's sufficient for the volume of CI runs.
Thanks. I just wanted to make sure the test was up-to-date. I noticed some of the std::format tests fail and I added several new parts of std::format last week.
Once this is in I will have to keep an eye on the load on the CI runner to make sure it's sufficient for the volume of CI runs.
Great! I already had a look and the last run took 39 minutes which is slightly more than Apple at 33 minutes. However there are more Apple jobs than runners. So I expect FreeBSD not to be the slowest runner.
Can you rebase onto main? I don't think you had D141294 in your tree.
LGTM once this is green. Thanks a bunch for the work, I am really glad to see this finally working and will be happy to advertise official support for FreeBSD.
I was away for a bit, and will get back to this. I've pushed a rebased test version to D140050 to check for any new regressions, and if it looks good I will push this.

__r |= static_cast<unsigned long long>(__first_[__i]) << (sizeof(__storage_type) * CHAR_BIT);
^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~I have one new XFAIL to add, in D145120, and one XFAIL to be removed from libcxx/test/libcxx/modules_include.sh.cpp.
Seeing an occasional timeout in libcxx/test/std/atomics/atomics.types.operations/atomics.types.operations.wait/atomic_wait_explicit.pass.cpp or other atomic tests
rebase
XFAIL removal in libcxx/test/libcxx/modules_include.sh.cpp is a separate commit
You'll need CC/CXX to be clang(++)-14 or higher here like the other generic-cxx2b jobs now that the default moved out of run-buildbot as of ca04b49597ccf137da9dfcbb1844d2e8b6a83c07
