Bug #19921: TestYJIT#test_bug_19316 test failure

• Status: Closed
• Assignee: yjit
• Target version: -
• ruby -v: ruby 3.3.0dev (2023-10-12 master 52709a4862) [x86_64-linux]
• Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN

[vo.x (Vit Ondruch)]

Testing with 52709a4862 on Fedora Rawhide, I observe following failure:

 94) Failure:
TestYJIT#test_bug_19316 [/builddir/build/BUILD/ruby-3.3.0-52709a4862/test/ruby/test_yjit.rb:1126]:
Expected no exits, but got
{:opt_and=>1}

Just FTR, previously I was testing with 904413997f and everything worked just fine.

This is failing (for me) since https://github.com/ruby/ruby/commit/492e9437dd33f64e283a9de21f49c65d3195c1f0

Interesting. Thx for looking into this. I saw this commit, but ruled it out initially. However, on the second look the exits: { opt_plus: 1 } from this hunk:

@@ -1153,7 +1153,7 @@ def foo
   end
 
   def test_invalidate_cyclic_branch
-    assert_compiles(<<~'RUBY', result: 2)

       def foo
         i = 0
         while i < 2

seem to correspond with the error message. That would mean that one test case might influence other, what would be unfortunate.

I cannot reproduce your problem in my x86_64-linux environment (Ubuntu 22.04). It also seems to succeed on Ruby CI's Fedora 38 x86_64 and all other CIs. It might be specific to how you build Ruby. Can you provide a way to reproduce your build environment on our end, e.g. with a Docker container?

94. Failure:

I see it's a 94th failure. What were the other failed tests?

"plus" and "and" are different.

That would mean that one test case might influence other, what would be unfortunate.

Each test runs in a separate subprocess.

Replying to the comment I can do quickly for now:

Actually the other 93 tests are "Skipped". So build log shows something like:

Finished tests in 557.802217s, 46.9037 tests/s, 11010.2933 assertions/s.
26163 tests, 6141566 assertions, 1 failures, 0 errors, 93 skips

Trying to reproduce this, I have hit this on x86_64 as well as on aarch64, while it passed on other architectures. The build is here:

https://koji.fedoraproject.org/koji/taskinfo?taskID=107436987

You can go into the architecture specific "descendants" builds, until you reach build.log, such as:

https://kojipkgs.fedoraproject.org//work/tasks/7059/107437059/build.log

All the dependencies installed for the build are listed here:

https://kojipkgs.fedoraproject.org//work/tasks/7059/107437059/root.log

The build seems to fail also on F38:

https://koji.fedoraproject.org/koji/taskinfo?taskID=107441872

This is the configuration and start of build:

I don't see anything that stands out in your build logs, so I'm still not sure if I can reproduce the issue myself. Since you seem to know how to reproduce this, could you consider reproducing the same issue on GitHub Actions (by modifying configs like .github/workflows/ubuntu.yml) so that we can see the issue on pull requests? If you can open a pull request that fails this test on GitHub Actions, that'd be appreciated. But right now, this is something the team cannot reproduce and investigate.

[vo.x (Vit Ondruch)]

@jaruga (Jun Aruga) could you please help with the reproducer. I think you are the best person 😇

Sure. Let me check this ticket later.

[k0kubun (Takashi Kokubun)]

Can you try the latest master (newer than 7a3a98e2be69fd3fa68e6ee1afa43c3160f22254)? https://github.com/ruby/ruby/pull/8689 might help.

[mtasaka (Mamoru TASAKA)]

I tried 6c46ccf226bc6440743b51af713864c062eba27f but I see the same test failure.

[k0kubun (Takashi Kokubun)]

I'm afraid we need a repro from you on CI (or anything I can exactly reproduce, like on Dockerfile) then. Subprocess tests like test_yjit in test-all generally seem to have a problem of picking a wrong Ruby, and it could be very much specific to how you set up your environment. So it's hard for us to look into it without such a repro.

Just FTR, there is no other Ruby installed in the environment during build, so this is certainly not an issue.

[k0kubun (Takashi Kokubun)]

OK, it explains why https://github.com/ruby/ruby/pull/8689 did not help. If that part is fine, I have nothing else to try until I get a repro.

[alanwu (Alan Wu)]

Could someone kick off a Koji build with 9047fe5ea4e8c989c1081aa10f741a413c546534
"YJIT: Print exit reasons on failure in test_yjit.rb"?
It adds some extra information to the failure message that should resolve this
mystery. This will likely be the last run we need to spend on this issue and is
mostly for my own curiosity. The failing test is fine with the exit; merely
checking the result is good enough (see ruby-core:112973 from 7 months ago).

Regardless of the outcome of the Koji attempt, we'll put exits: :any on the
test in a day or so to resolve this issue.

Thanks! The new message confirms the issue. The test should pass now, as of fab70183.

Thanks for the fix! I am glad for that.

https://github.com/ruby/ruby/commit/fab7018346488a693d34ea81f1e9d6fec476f06e

Because the & call checks for interrupts, the test was accidentally
timing dependent. Stop checking for exits.

Seeing the commit message, what the "& call checks" mean? What makes the failure?

I observed that the test TestYJIT#test_bug_19316 failed for the Ruby (based on the ef3f9f1a685effb51543d1f08831692fa68863a2 + patch files) before the fixed commit, on Fedora rawhide (Fedora 40), 39, 38 every time so far.

Below is the command log on Fedora's build environment (called mock environment) for the Ruby above.

I was planning to check the variations of the builds to find which factor causes the failure. But as you fixed the issue, I will pend the investigation happily for now.

• Ruby + no additional patches + the compiler flags used to build RPM in Fedora + Fedora's build environment.
• Ruby + no additional patches + the compiler flags used to build RPM in Fedora + RubyCI Fedora 38 server.

Seeing the commit message, what the "& call checks" mean? What makes the failure?

It's the a & b call to Integer#& in the test. The failure was from a time-based interrupt, which is used for thread switching and for IO operations like stat(2) which Kernel#require uses. The test itself shouldn't be doing any IO, but I see that you carry ruby-2.7.0-Initialize-ABRT-hook.patch, which makes the VM use Kernel#require on boot. That might be the source of the interrupt.

This is pure speculation; you can try testing without the patch if you're curious.
