Raymond Hettinger 62f4dad816 Issue 21137: Better repr for threading.Lock() 2014-05-25 18:22:35 -07:00
Victor Stinner e8794526db threading.RLock._acquire_restore() now raises a TypeError instead of a
SystemError when it is not called with 2 arguments

Victor Stinner bd303c165b Issue #19512, #19515: remove shared identifiers, move identifiers where they
are used.

Move also _Py_IDENTIFIER() defintions to the top in modified files to remove
identifiers duplicated in the same file.

Victor Stinner 090543736f Issue #19512: add some common identifiers to only create common strings once,
instead of creating temporary Unicode string objects

Add also more identifiers in pythonrun.c to avoid temporary Unicode string
objets for the interactive interpreter.

Victor Stinner 357f5155dc Issue #19437: Fix _threading.RLock constructor (rlock_new), call
Py_DECREF(self) if PyThread_allocate_lock() failed instead of calling directly
type->tp_free(self), to keep the chained list of objects consistent when Python
is compiled in debug mode

fails, don't consume the row (restore it) and fail immediatly (don't call
pysqlite_step())

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.

R David Murray 95b7110a11 #17091: update docstring for _thread.Lock.acquire.
The main docs were fixed to remove mention of None long ago,
but the docstring was not.  Reported by Armin Rigo, patch
by Ian Cordasco.

Victor Stinner 754851f456 Issue #11223: Add threading._info() function providing informations about the
thread implementation.

Skip test_lock_acquire_interruption() and test_rlock_acquire_interruption() of
test_threadsignals if a thread lock is implemented using a POSIX mutex and a
POSIX condition variable. A POSIX condition variable cannot be interrupted by a
signal (e.g. on Linux, the futex system call is restarted).

  #Issue3088 in-progress: Race condition with instances of classes derived from threading.local:

  When a thread touches such an object for the first time, a new thread-local __dict__ is created,
  and the __init__ method is run.
  But a thread switch can occur here; if the other thread touches the same object, it installs another
  __dict__; when the first thread resumes, it updates the dictionary of the second...

  This is the deep cause of the failures in test_multiprocessing involving "managers" objects.

  Also a 2.5 backport candidate.
