Victor Stinner ae58649721 Issue #22043: time.monotonic() is now always available 
threading.Lock.acquire(), threading.RLock.acquire() and socket operations now
use a monotonic clock, instead of the system clock, when a timeout is used.

Tim Peters a577f1e0f1 Changed a comment to end grammar bikeshedding ;-) 2013-10-26 11:56:16 -05:00
Tim Peters 7bad39f174 Fiddled Thread.join() to be a little simpler. Kinda ;-) 2013-10-25 22:33:52 -05:00
Tim Peters e5bb0bf04d Issue #19399: fix sporadic test_subprocess failure. 
Change Thread.join() with a negative timeout to just return.  The
behavior isn't documented then, but this restores previous
behavior.

Tim Peters 72460fa68b Get "stopped" back into repr(Thread) when appropriate. 
Due to recent changes, a Thread doesn't know that it's over before
someone calls .join() or .is_alive().  That meant repr(Thread)
continued to include "started" (and not "stopped") before one of
those methods was called, even if hours passed since the thread
ended.

Repaired that.

Tim Peters b5e9ac9ec6 Another stab at the thread cleanup patch. 
Antoine Pitrou found a variation that worked for him on the
thread+fork tests, and added an important

    self._is_stopped = True

to the after-fork code.  I confess I don't know why things passed
before.  But then mixing fork with threads is insane ;-)

Tim Peters 7875523f16 Backed out changeset 1f5a7853680c 
Unixy buildbots were failing the thread + fork tests :-(
 2013-09-09 13:47:16 -05:00
Tim Peters 7a6054b19d Minor cleanup of the new scheme for detecting thread termination. 
Documented some obscurities, and assert'ed ._stop()'s crucial precondition.

Tim Peters c363a23eff Issue 18984: Remove ._stopped Event from Thread internals. 
The fix for issue 18808 left us checking two things to be sure a Thread
was done:  an Event (._stopped) and a mutex (._tstate_lock).  Clumsy &
brittle.  This patch removes the Event, leaving just a happy lock :-)

The bulk of the patch removes two excruciating tests, which were
verifying sanity of the internals of the ._stopped Event after a fork.
Thanks to Antoine Pitrou for verifying that's the only real value
these tests had.

One consequence of moving from an Event to a mutex:  waiters (threads
calling Thread.join()) used to block each on their own unique mutex
(internal to the ._stopped event), but now all contend on the same
mutex (._tstate_lock).  These approaches have different performance
characteristics on different platforms.  I don't think it matters in
this context.

Antoine Pitrou 5da7e7959e Issue #18808 again: fix the after-fork logic for not-yet-started or already-stopped threads. 
(AFAICT, in theory, we must reset all the locks, not just those in use)
 2013-09-08 13:19:06 +02:00
Tim Peters 68d7f78703 Issue 18808: blind attempt to repair some buildbot failures. 
test_is_alive_after_fork is failing on some old Linux kernels, but
passing on all newer ones.  Since virtually anything can go wrong
with locks when mixing threads with fork, replace the most likely
cause with a redundant simple data member.

Antoine Pitrou 7b4769937f Issue #18808: Thread.join() now waits for the underlying thread state to be destroyed before returning. 
This prevents unpredictable aborts in Py_EndInterpreter() when some non-daemon threads are still running.

   QueryPerformanceCounter()
 * time.monotonic() uses CLOCK_HIGHRES if available
 * Add time.get_clock_info(), time.perf_counter() and time.process_time()
