Eric Snow 2ebc5ce42a bpo-30860: Consolidate stateful runtime globals. (#3397) 
* group the (stateful) runtime globals into various topical structs
* consolidate the topical structs under a single top-level _PyRuntimeState struct
* add a check-c-globals.py script that helps identify runtime globals

Other globals are excluded (see globals.txt and check-c-globals.py).

Serhiy Storchaka aefa7ebf0f bpo-6532: Make the thread id an unsigned integer. (#781) 
* bpo-6532: Make the thread id an unsigned integer.

From C API side the type of results of PyThread_start_new_thread() and
PyThread_get_thread_ident(), the id parameter of
PyThreadState_SetAsyncExc(), and the thread_id field of PyThreadState
changed from "long" to "unsigned long".

* Restore a check in thread_get_ident().

Victor Stinner 13019fdef3 Issue #22117: Add a new _PyTime_FromSeconds() function 
Fix also _Py_InitializeEx_Private(): initialize time before initializing
import, import_init() uses the _PyTime API (for thread locks).
 2015-04-03 13:10:54 +02:00
Victor Stinner 6aa446cf03 PEP 475: on EINTR, retry the function even if the timeout is equals to zero 
Retry:

* signal.sigtimedwait()
* threading.Lock.acquire()
* threading.RLock.acquire()
* time.sleep()

Victor Stinner 869e1778c0 Issue #22117: Replace usage of _PyTime_ROUND_UP with _PyTime_ROUND_CEILING 
All these functions only accept positive timeouts, so this change has no effect
in practice.
 2015-03-30 03:49:14 +02:00
Victor Stinner f5faad2bf0 Issue #22117: The thread module uses the new _PyTime_t timestamp API 
Add also a new _PyTime_AsMicroseconds() function.

threading.TIMEOUT_MAX is now be smaller: only 292 years instead of 292,271
years on 64-bit system for example. Sorry, your threads will hang a *little
bit* shorter. Call me if you want to ensure that your locks wait longer, I can
share some tricks with you.

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.

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.
 2013-11-07 23:07:29 +01:00
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.

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).

Antoine Pitrou 7c3e577395 Issue #7316: the acquire() method of lock objects in the :mod:`threading` 
module now takes an optional timeout argument in seconds.  Timeout support
relies on the system threading library, so as to avoid a semi-busy wait
loop.
