2019-01-10	Fixing select call to not enforce RLIMIT_NOFILE.	Zach Koopmans
	Removing check to RLIMIT_NOFILE in select call. Adding unit test to select suite to document behavior. Moving setrlimit class from mlock to a util file for reuse. Fixing flaky test based on comments from Jamie. PiperOrigin-RevId: 228726131 Change-Id: Ie9dbe970bbf835ba2cca6e17eec7c2ee6fadf459
2019-01-09	Make CooperativeSaveEnabled() async-signal-safe(r).	Jamie Liu
	The static local variable `enabled` in CooperativeSaveEnabled() is not initialized until the first call to CooperativeSaveEnabled(), per the C++14 standard, section 6.7 ("Declaration statement"), paragraph 4. This initialization is thread-safe as of C++11, but it is not required to be async-signal-safe. Use a namespace-scope variable instead, since this is guaranteed to be zero-initialized before main() by section 3.6.2 ("Initialization of non-local variables"). getenv() is technically not async-signal-safe either, hence the hedging in the change summary line. However, glibc's implementation of getenv() appears to be async-signal-safe in the absence of calls to setenv(). PiperOrigin-RevId: 228588617 Change-Id: I669f555d1c91352d55c606970bb237ec888fa7ca
2018-12-27	Fix deadlock between epoll_wait and getdents	Fabricio Voznika
	epoll_wait acquires EventPoll.listsMu (in EventPoll.ReadEvents) and then calls Inotify.Readiness which tries to acquire Inotify.evMu. getdents acquires Inotify.evMu (in Inotify.queueEvent) and then calls readyCallback.Callback which tries to acquire EventPoll.listsMu. The fix is to release Inotify.evMu before calling Queue.Notify. Queue is thread-safe and doesn't require Inotify.evMu to be held. Closes #121 PiperOrigin-RevId: 227066695 Change-Id: Id29364bb940d1727f33a5dff9a3c52f390c15761

2018-12-19	Implement pwritev2.	Zach Koopmans
	Implement pwritev2 and associated unit tests. Clean up preadv2 unit tests. Tag RWF_ flags in both preadv2 and pwritev2 with associated bug tickets. PiperOrigin-RevId: 226222119 Change-Id: Ieb22672418812894ba114bbc88e67f1dd50de620

2018-12-11	Add rvalue ref-qualified PosixErrorOr<T>::ValueOrDie() overloads.	Jamie Liu
	This allows ValueOrDie() to be called on PosixErrorOr rvalues (e.g. temporaries) holding move-only types without extraneous std::move()s. PiperOrigin-RevId: 225098036 Change-Id: I662862e4f3562141f941845fc6e197edb27ce29b
