d1aea30b2a Fix POSIX timer thread naming.
Spencer Low points out that we never actually set a name because the constant
part of the string was longer than the kernel's maximum, and the kernel
rejects long names rather than truncate.

Shorten the fixed part of the string while still keeping it meaningful. 9999
POSIX timers should be enough for any process...

094f58fb2a Revert "Unregister pthread_atfork handlers on dlclose()"
The visibility control in pthread_atfork.h is incorrect.
 It breaks 64bit libc.so by hiding pthread_atfork.

 This reverts commit 6df122f852.

3391a9ff13 Simplify close(2) EINTR handling.
This doesn't affect code like Chrome that correctly ignores EINTR on
close, makes code that tries TEMP_FAILURE_RETRY work (where before it might
have closed a different fd and appeared to succeed, or had a bogus EBADF),
and makes "goto fail" code work (instead of mistakenly assuming that EINTR
means that the close failed).

Who loses? Anyone actively trying to detect that they caught a signal while
in close(2). I don't think those people exist, and I think they have better
alternatives available.

Prebuilt shared libraries (libclang.so, libLLVM.so and etc) have been
moved to prebuilts/sdk/tools/linux/lib64. Update the search path in

Yabin Cui
95f1ee235a Change on handling of SIGEV_THREAD timers.
1. Don't prevent calling callback when SIGEV_THREAD timers are disarmed by timer_settime.
As in POSIX standard: The effect of disarming or resetting a timer with pending
expiration notifications is unspecified. And glibc didn't prevent in this situation, so I
think it is fine to remove the support.
2. Still prevent calling callback when SIGEV_THREAD timers are deleted by timer_delete.
As in POSIX standard: The disposition of pending signals for the deleted timer is unspecified.
However, glibc handles this (although that is not perfect). And some of our tests in
time_test.cpp depend on this feature as described in b/18039727. so I retain the support.
3. Fix some flaky test in time_test.cpp, and make "time*" test pass on bionic-unit-tests-glibcxx.

Changes affecting future time stamps

    Mongolia will start observing DST again this year, from the last
    Saturday in March at 02:00 to the last Saturday in September at 00:00.
    (Thanks to Ganbold Tsagaankhuu.)

    Palestine will start DST on March 28, not March 27.  Also,
    correct the fall 2014 transition from September 26 to October 24.
    Adjust future predictions accordingly.  (Thanks to Steffen Thorsen.)

  Changes affecting past time stamps

    The 1982 zone shift in Pacific/Easter has been corrected, fixing a 2015a
    regression.  (Thanks to Stuart Bishop for reporting the problem.)

    Some more zones have been turned into links, when they differed
    from existing zones only for older time stamps.  As usual,
    these changes affect UTC offsets in pre-1970 time stamps only.
    Their old contents have been moved to the 'backzone' file.
    The affected zones are: America/Antigua, America/Cayman,
    Pacific/Midway, and Pacific/Saipan.

  Changes affecting time zone abbreviations

    Correct the 1992-2010 DST abbreviation in Volgograd from "MSK" to "MSD".
    (Thanks to Hank W.)

76615dae93 Provide writer preference option in rwlock.
Previous implementation of rwlock contains four atomic variables, which
is hard to maintain and change. So I make following changes in this CL:

1. Add pending flags in rwlock.state, so we don't need to synchronize
between different atomic variables. Using compare_and_swap operations
on rwlock.state is enough for all state change.

2. Add pending_lock to protect readers/writers waiting and wake up
operations. As waiting/wakeup is not performance critical, using a
lock is easier to maintain.

3. Add writer preference option.

4. Add unit tests for rwlock.
