a3f4977217 Add thread name for background threads. 2017-06-23 10:54:54 -07:00

52fc887b49 Avoid inactivity_check within background threads. 
Passing is_background_thread down the decay path, so that background thread
itself won't attempt inactivity_check.  This fixes an issue with background
thread doing trylock on a mutex it already owns.

37f3fa0941 Mask signals during background thread creation. 
This prevents signals from being inadvertently delivered to background
threads.

9b1befabbb Add minimal initialized TSD. 
We use the minimal_initilized tsd (which requires no cleanup) for free()
specifically, if tsd hasn't been initialized yet.

Any other activity will transit the state from minimal to normal.  This is to
workaround the case where a thread has no malloc calls in its lifetime until
during thread termination, free() happens after tls destructors.

84f6c2cae0 Log decay->nunpurged before purging. 
During purging, we may unlock decay->mtx.  Therefore we should finish logging
decay related counters before attempt to purge.

a4d6fe73cf Only abort on dlsym when necessary. 
If neither background_thread nor lazy_lock is in use, do not abort on dlsym
errors.

d955d6f2be Fix extent_hooks in extent_grow_retained(). 
This issue caused the default extent alloc function to be incorrectly
used even when arena.<i>.extent_hooks is set.  This bug was introduced
by 411697adcd (Use exponential series to
size extents.), which was first released in 5.0.0.

813643c6a7 Prevent background threads from running in post_reset(). 
We lookup freed extents for testing in post_reset.  Take background_thread lock
so that the extents are not modified at the same time.

b83b5ad44a Not re-enable background thread after fork.

464cb60490 Move background thread creation to background_thread_0. 
To avoid complications, avoid invoking pthread_create "internally", instead rely
on thread0 to launch new threads, and also terminating threads when asked.

73713fbb27 Drop high rank locks when creating threads. 
Avoid holding arenas_lock and background_thread_lock when creating background
threads, because pthread_create may take internal locks, and potentially cause
deadlock with jemalloc internal locks.

00869e39a3 Make tsd no-cleanup during tsd reincarnation. 
Since tsd cleanup isn't guaranteed when reincarnated, we set up tsd in a way
that needs no cleanup, by making it going through slow path instead.

29c2577ee0 Remove assertions on extent_hooks being default. 
It's possible to customize the extent_hooks while still using part of the
default implementation.
