Hello Peter,

Those test results show a clear regression (6 PASS->FAIL
transistions).

I noticed that the same tests have been fixed with the whinlatter
upgrade:
https://lore.kernel.org/openembedded-core/c5401d89c51fe73d93afc73d73cb0f93c00bbca7.1769845858.git.yoann.congal@smile.fr/

I'm not familiar with the glibc stable policy but shouldn't we wait the
next cycle to get the fix for those tests and avoid triggering this
regression in the meantime?

What do you think?

I have bisected the problem to following commit:
https://sourceware.org/git/?p=glibc.git;a=commit;h=fb22fd3f5b415dd4cd6f7b5741c2f0412374e242

When reverting just the test change from there (keeping CVE fix), the 5 malloc tests succeed.
So from this point of view, we could look at this as regression of the testsuite, or adding new failing tests without failing the already present ones.

Re: [scarthgap][PATCH] glibc: stable 2.39 branch updates

Hello Peter,

We sometimes see regressions in glibc test runs depending on the local environment. In such cases, it can help to re-trigger the tests to check whether the failures are consistently reproducible. It may also be useful to cross-check the results with autobuilder runs, which generally provide a more stable baseline before concluding on regressions.

Thanks,
Hemanth

I'm willing to test this on the autobuilder. But I never done that...
Any pointer? Where do I get the nice test report with the comparison to
the previous version?

Thanks!

I am planning to run the testsuites again during weekend.
I also find it weird that every update shows different "before" results than previous one showin in "after" result.
Not sure if it's flakiness or local conditions like CPU overload at time of running tests.

The tests are run via "bitbake glibc-testsuite -c check"

The comparison table is created manually from task logfile.
Basic testcase changes can be extracted from the same file.
New/Removed tests need to be extracted from result files, bit of manual work.

For context, many of the 'toolchain' testsuites have some flaky tests
in them and we don't always see consistent output.

For example, the 5.0.14 regression report mentions:

https://downloads.yoctoproject.org/releases/yocto/yocto-5.0.14/testresults/testresult-regressions-report.txt

Regression:  oeselftest_almalinux-8.10_qemuarm_20251014024649
             oeselftest_almalinux-9.7_qemuarm_20251118011611
    Total: 3 new regression(s):
    1 regression(s) for ptestresult.gcc-libstdc++-v3-user
        ptestresult.gcc-libstdc++-v3-user.30_threads/async/async.cc execution test: PASS -> FAIL
    2 regression(s) for ptestresult.glibc-user
        ptestresult.glibc-user.misc/tst-linux-mremap1: UNSUPPORTED -> FAIL
        ptestresult.glibc-user.misc/tst-pidfd: UNSUPPORTED -> FAIL

or:

    5 regression(s) for ptestresult.glibc
        ptestresult.glibc.elf/ifuncmain8: PASS -> No matching test result
        ptestresult.glibc.elf/tst-tls20: PASS -> FAIL
        ptestresult.glibc.iconvdata/mtrace-tst-loading: PASS -> FAIL
        ptestresult.glibc.iconvdata/tst-loading: PASS -> FAIL
        ptestresult.glibc.nptl/tst-thread-affinity-pthread: PASS -> FAIL

over time we've been trying to investigate and resolve these kinds of
issues but we're obviously not there yet.


I can say we've made big improvements, you can see it in the numbers,
e.g. comparing:

https://downloads.yoctoproject.org/releases/yocto/yocto-4.0/testreport.txt - 142,413 failures
https://downloads.yoctoproject.org/releases/yocto/milestones/yocto-5.3_M3/testreport.txt 1,636 failures

which shows a definite improvement! The number of flaky test results
has also decreased but is obviously not as easy to measure.

We have a policy with ptests and rust of no failures. We're trying to
get there with gcc/binutils/glibc/ltp.

The test results are stored in the testresults.json files and
resulttool knows how to generate reports and compare files for
regression reports.

The plus side of the autobuilder results is that we have a long
baseline for comparison and a relatively stbale testing environment
which should be consistent.

Cheers,

Richard

Hello Yoann,

You can trigger a *qemux86-64-tc* build with this patch applied. Once 
the build completes, the corresponding results link will be available in 
the published artifacts.

example: 
https://valkyrie.yocto.io/pub/non-release/20260206-8/testresults/qemux86-64-tc/

The *qemux86-64-tc* build artifacts include the |test-results.json| 
file. You can compare this against any recent successful *qemux86-64-tc* 
autobuilder run as the baseline.

Hope this helps.

Thanks, Hemanth

That does! Thanks!

The result from my first run of this branch (with this patch) shows no
malloc failure:
https://valkyrie.yocto.io/pub/non-release/20260203-124/testresults/qemux86-64-tc/testresults.json

So, what I plan to do:
Take this patch into my branch, test it when the branch is ready and add
this info to the commit message.

Replaced non-standard exit codes and fixed premature exits to avoid masking failures.

-Subject: [PATCH] aarch64: fix check for SVE support in assembler
-
-Due to GCC bug 110901 -mcpu can override -march setting when compiling
-asm code and thus a compiler targetting a specific cpu can fail the
-configure check even when binutils gas supports SVE.
-
-The workaround is that explicit .arch directive overrides both -mcpu
-and -march, and since that's what the actual SVE memcpy uses the
-configure check should use that too even if the GCC issue is fixed
-independently.
-
-Upstream-Status: Backport [https://sourceware.org/git/?p=glibc.git;a=commit;h=73c26018ed0ecd9c807bb363cc2c2ab4aca66a82]

Regression testing is done and below are the results:

Before glibc update:
-------------------------------------------------
Recipe       | Passed     | Failed   | Skipped  |
-------------------------------------------------
glibc        | 5037       | 123      | 156      |
glibc-user   | 4858       | 231      | 227      |
-------------------------------------------------

After glibc update:
-------------------------------------------------
Recipe       | Passed     | Failed   | Skipped  |
-------------------------------------------------
glibc        | 5043       | 123      | 156      |
glibc-user   | 4866       | 229      | 227      |
-------------------------------------------------

ptest shows below tests as failed after glibc update:
tst-malloc-fork-deadlock-malloc-check, tst-robustpi7, tst-thread-affinity-pthread2
