glibc 2.22 --- Stil frozen. Machine maintainers start testing.

glibc 2.22 --- Stil frozen. Machine maintainers start testing.

[Carlos O'Donell]

This is a reminder that master is still frozen.

Only bug fixes and documentation patches.

Machine maintainers should *start* testing to make sure you 
don't run into any unforseen problems.

I'd like to have the last bug fixes in by the end of the week.

Cheers,
Carlos.

aarch64 status:

FAIL: debug/tst-backtrace5
FAIL: debug/tst-backtrace6
there is a fix as part of the cancel changes:
https://sourceware.org/ml/libc-alpha/2015-06/msg00950.html
i can fix this independently, but i think it is ok
to delay this until next release and do it with the
cancellation fixes.

i'm testing a fix for gcc, binutils and glibc.
the glibc change is simple.

this fails in my test environment, but it is a test bug.

other pending issues:

i will work on this, but probably won't be in this release.

holding the rtld lock.

i don't know about any fix for this.

ia64 has a few nptl crashes i need to look further into, but they also
fail with glibc-2.21 now (they didn't before), so i'm guessing a system
level change is behind it.

I have been seeing this consistently on x86_64 for some time now and I
remember (although my memory is usually quite faulty) concluding that
it needed a newer binutils.

Just FYI, powerpc64 and powerpc64le are looking good so far. No abnormalities in the build process or testsuite. I’ll post an update here when I finish testing for 32 bit.

As far as I know there hasn't been a call for updated translations.
If there are changes to the messages please upload the master po-file to
the translation project so the translators have a chance to update their
language files.

this is the cause of nptl/tst-stack4 failure, it affects all archs,
it happens about once out of 100 runs here on aarch64.

Inconsistency detected by ld.so: dl-tls.c: 493: _dl_allocate_tls_init: 
Assertion `listp->slotinfo[cnt].gen <= _rtld_local._dl_tls_generation' 
failed!

is this a regression ?  if not, has it increased in frequency ?  if not,
and there isn't a clear fix, i'm not sure it qualifies as a blocker.

it's not new, the frequency actually decreased since
https://sourceware.org/ml/libc-alpha/2015-03/msg00563.html
was committed.

If you tell me your wiki login name then I can add you, and you
can add your test results to the wiki.

Given it's an existing bug we'll try to tackle this in the more thorough
P&C cleanup for that code in 2.23.
