1. Current status

The release branch of glibc-2.27 is maintained by Dmitry V. Levin and was released on 2018-02-01. There are no immediate plans for the next release.

The ref structure of this branch is:

release/2.27/master: main branch
glibc-2.27.N: revision releases tagged out of release/2.27/master

These people are interested in contents and further revisions tagged on the branch:

<Add your name here>

The general policies for release branches apply to this branch. Do you think a certain bugfix should be included in this branch?

Is the fix committed in master? It has to be, unless it's not applicable to master (e.g. code has been rewritten meantime).
Do you have commit permissions? If so, go ahead if you think it's reasonably safe. break;
Can you handle Git yourself? Then you can clone the glibc repository, cherry-pick the appropriate fixes, push your branch out and send a pull request at libc-alpha. break;
Add the glibc_2.27 keyword to the appropriate bug report.
If there is no appropriate bug report, send a request for the fix to be included to libc-alpha.

A revision release is tagged either when some critical bug-fix appears, or after some period of real-world testing, usually mainly in some SUSE distribution branch (but other distributions are welcome to run latest release/2.27/master as well, more so if they tell me about it!).

2. Planning

What things do we want to accomplish this release?

2.1. Release blockers?

Reported failure on Intel hardware involving steam/mono runtimes?
- setjmp changes?
- commit f81ddabffd also breaks software like vlc or amarok, they crash with a segmentation fault during startup
- commmit 2ec0e7eade0ea1258acd5c6f5e5e9bfaeb5041a8 restores ABI.
Month names in alternative grammatical case
- commits 95cb863a1ef7760a11272bbd7ba5fe62dc41be54, 761a585ce9245d5ad968303b200eef1f26fd501c, and 22390764f9ef3b04ae71ad100af6282f677315c2

2.2. Desirable this release?

RISC-V port
C11 threads
- In review by Carlos O'Donell.
- Postponed to 2.28
Istvan Kurucsai's malloc security patches (1/7 2/7 3/7 4/7 5/7 6/7 7/7) - (DJ's +1)
- Postponed to 2.28
Don't include libio.h from the installed stdio.h -- given Florian's concerns in https://sourceware.org/ml/libc-alpha/2018-01/msg00242.html we may want to go even farther and stop installing libio.h at all, or else we may want to back out https://sourceware.org/ml/libc-alpha/2017-12/msg00869.html
- Postponed to 2.28
Bug 14095 - Review / update collation data from Unicode / ISO 14651
- Work on this is almost finished, patch will be sent to the mailing list in a few days.
- Postponed to 2.28

3. Build and test issues

Describe build and test issues for each architecture, or confirm a clean build with no testsuite failures. The list below is not a complete list of ABI variants; testing should try to cover the different ABI variants as far as possible.

Build system: UNAME -a, GCC?, Binutils?, Kernel ?

TRIMMED LIST OF FAILURES.

3.1. Architecture-independent

On systems with limited memory, stdio-common/test-vfprintf and stdio-common/bug22 may fail (bug 14231).
If cross-testing, and the physical path to the build directory is different on the build system and the host used for testing (if it involves a symlink on one system but not the other), io/ftwtest fails.
If cross-testing and the system on which glibc runs does not have cpp (used by rpcgen), sunrpc/bug20790 fails.
If cross-testing and the system on which glibc runs does not have python3 or python (whichever was found by configure on the build system), the pretty printers tests fail:
```
FAIL: nptl/test-cond-printers
FAIL: nptl/test-condattr-printers
FAIL: nptl/test-mutex-printers
FAIL: nptl/test-mutexattr-printers
FAIL: nptl/test-rwlock-printers
FAIL: nptl/test-rwlockattr-printers
```
Similarly if the system lacks PExpect 4.0 or newer the same tests fail. Similarly if the system lacks gdb 7.8 or newer the same tests fail.
On systems with Linux kernel 3.11 through 3.17, missing a backport of commit 69a91c237ab0ebe4e9fdeaf6d0090c85275594ec (present in 3.18, backports may be in some older stable series), io/tst-open-tmpfile fails.
timezone/tst-tzset creates a 4GB file in $TMPDIR and fails if there is not enough disk space.
If the test system does not have suitable copies of libgcc_s.so and libstdc++.so installed in system library directories, it is necessary to copy or symlink them into the build directory before testing (see https://sourceware.org/ml/libc-alpha/2012-04/msg01014.html regarding the use of system library directories here).
misc/tst-ttyname - Testcase error. Debug information needed. The results vary according to the kernel version.
nptl/tst-eintr1 - Allegedly kernel issue.
intl/tst-gettext - fails with new msgfmt.
nptl/tst-stack4 - On some targets this may fail occasionally because of a data race (bug 19329).

assert/tst-assert-*++, nptl/tst-thread_local1 and stdlib/tst-*quick_exit are unsupported because C++ compiler/runtime in "RHEL for ARM" lacks thread local support.
iconv/tst-gconv-init-failure is unsupported because the aarch64 "RHEL for ARM" kernel does not support:

getauxval (AT_EXECFN);

math/test-f*except-traps are unsupported because we do not support on aarch64:

feenableexcept (FE_ALL_EXCEPT)

math/test-nearbyint-except-2 is unsupported because we do not support on aarch64:

feenableexcept (FE_INEXACT)

misc/tst-pkey is unsupported because the "RHEL for ARM" kernel does not support memory protection keys.
nptl/*-printers are unsupported because pexpect < 4.0.

Build system: gcc version 7.3.0 (Debian 7.3.0-1), GNU ld (GNU Binutils for Debian) 2.30, 3.16.7-ckt7 (Adhemerval Zanella)

The system toolchain used has a out-of-tree patch applied (local-fpcscr_values.diff from libc6-dev debian package) which changes architecture ABI. This breaks glibc testsuite build with a missing __fpscr_values symbol. The following patch was applied on glibc source to avoid this issue (a better alternative would be to rebuild a full toolchain):

$ cat local-fpcscr_values.diff

Most math issues seems related to qNaN/sNaN expectation. For instance math/test-double-acos:

Failure: acos (qNaN): Exception "Invalid operation" set
Failure: Test: acos (qNaN)
Result:
 is:         sNaN
 should be:  qNaN
Failure: acos (-qNaN): Exception "Invalid operation" set
Failure: Test: acos (-qNaN)
Result:
 is:         sNaN
 should be:  qNaN
Failure: acos (sNaN): Exception "Invalid operation" not set
Failure: Test: acos (sNaN)
Result:
 is:         sNaN
 should be:  qNaN
Failure: acos (-sNaN): Exception "Invalid operation" not set
Failure: Test: acos (-sNaN)
Result:
 is:         sNaN
 should be:  qNaN
Failure: acos_towardzero (qNaN): Exception "Invalid operation" set
Failure: Test: acos_towardzero (qNaN)
Result:
 is:         sNaN
 should be:  qNaN
Failure: acos_towardzero (-qNaN): Exception "Invalid operation" set
Failure: Test: acos_towardzero (-qNaN)
Result:
 is:         sNaN
 should be:  qNaN
Failure: acos_towardzero (sNaN): Exception "Invalid operation" not set
Failure: Test: acos_towardzero (sNaN)
Result:
 is:         sNaN
 should be:  qNaN
Failure: acos_towardzero (-sNaN): Exception "Invalid operation" not set
Failure: Test: acos_towardzero (-sNaN)
Result:
 is:         sNaN
 should be:  qNaN

intl/tst-gettext - fails with new msgfmt.
nptl/tst-robust-fork fails with a most likely a kernel issue:

error: xpthread_check_return.c:32: pthread_mutex_destroy: Device or resource busy
error: 1 test failures

rt/tst-cpuclock2 fails with a transient issues most likely due system load (running it manually shows no issue):

live thread before sleep => 0.004000000
self thread before sleep => 0.004000000
live thread after sleep => 0.456000000
self thread after sleep => 0.004000000

stdlib/tst-strtod-round and wcsmbs/tst-wcstod-round failure outputs are too large to reproduce (1.6M) and last message indicates inexact issue (inexact 0 not 1).
stdlib/tst-tininess.out fails with:

assert/tst-assert-*++, nptl/tst-thread_local1 and stdlib/tst-*quick_exit are unsupported because C++ compiler/runtime in RHEL7 lacks thread local support.
io/tst-open-tmpfile is unsupported because kernel does not support O_TMPFILE.
misc/tst-pkey is unsupported because the RHEL7 kernel does not support memory protection keys on ppc64le.
nptl/*-printers are unsupported because pexpect < 4.0.
posix/tst-sysconf-empty-chroot needs a multiprocessor system and my test machine unfortunately wasn't one this time.

assert/tst-assert-*++, nptl/tst-thread_local1 and stdlib/tst-*quick_exit are unsupported because C++ compiler/runtime in RHEL7 lacks thread local support.
The lack of AVX and AVX2 on this hardware means that tst-audit10 and all the *avx* and *avx2* tests are unsupported.
The io/tst-open-tmpfile test is unsupported because of a lack of kernel support.
The C++ support in RHEL7 lacks thread local so the related thread local tests are disabled. Related tests are assert/tst-assert-*++, nptl/tst-thread_local1 and stdlib/tst-*quick_exit.
The *printers tests are unsupported because of pexpect < 4.0

3.28. x86 (32-bit, Hurd)

4. Packaging Changes

4.1. Abort no longer flushes stdio streams

The abort function terminates the process immediately, without flushing stdio streams. Previous glibc versions used to flush streams, resulting in deadlocks and further data corruption. This change also affects process aborts as the result of assertion failures.

4.2. ldconfig now processes includes directive in C/POSIX collation ordering

The ldconfig utility now processes `include' directives using the C/POSIX collation ordering. Previous glibc versions used locale-specific ordering, the change might break systems that relied on that.

4.3. Statically compiled applications using locales

Statically compiled applications attempting to load locales compiled for the GNU C Library version 2.27 will fail and fall back to the builtin C/POSIX locale. The reason for this is that the addition of the new "%OB" and "%Ob", support for two grammatical forms of the month names, also extends the locale data binary format. Static applications needing locale support must be recompiled to match the runtime and data they are deployed with. In some distributions there is an upgrade window where dynamically linked applications may use a new library but the old locale data and also fall back to the builtin C/POSIX locales; restarting the application process is sufficient to fix this.
