"asyncio primitives are not thread-safe, therefore they should not be used "
"for OS thread synchronization (use :mod:`threading` for that);"

"An Event object manages an internal flag that can be set to *true* with the :"

#: library/asyncio-sync.rst:171
msgid "A Condition object.  Not thread-safe."
#: library/asyncio-sync.rst:173
"An asyncio condition primitive can be used by a task to wait for some event "
"to happen and then get exclusive access to a shared resource."
#: library/asyncio-sync.rst:177
"In essence, a Condition object combines the functionality of an :class:"
"`Event` and a :class:`Lock`.  It is possible to have multiple Condition "
"objects share one Lock, which allows coordinating exclusive access to a "
"shared resource between different tasks interested in particular states of "
"that shared resource."
#: library/asyncio-sync.rst:183
"The optional *lock* argument must be a :class:`Lock` object or ``None``.  In "
"the latter case a new Lock object is created automatically."

"The preferred way to use a Condition is an :keyword:`async with` statement::"
#: library/asyncio-sync.rst:213

"*locked* and returns ``True``."

"Wake up at most *n* tasks (1 by default) waiting on this condition.  The "
"method is no-op if no tasks are waiting."
#: library/asyncio-sync.rst:238

"after.  If called with an *unlocked* lock a :exc:`RuntimeError` error is "

#: library/asyncio-sync.rst:233
msgid "Wake up all tasks waiting on this condition."

#: library/asyncio-sync.rst:253
"If the calling task has not acquired the lock when this method is called, a :"
"exc:`RuntimeError` is raised."
#: library/asyncio-sync.rst:256
"This method releases the underlying lock, and then blocks until it is "
"awakened by a :meth:`notify` or :meth:`notify_all` call. Once awakened, the "
"Condition re-acquires its lock and this method returns ``True``."
#: library/asyncio-sync.rst:263
msgid "Wait until a predicate becomes *true*."
msgstr "Attends jusqu'à ce qu'un prédicat devienne vrai."

msgid "Semaphore"
msgstr "Sémaphore"
#: library/asyncio-sync.rst:275
msgid "A Semaphore object.  Not thread-safe."
#: library/asyncio-sync.rst:277
"A semaphore manages an internal counter which is decremented by each :meth:"
"`acquire` call and incremented by each :meth:`release` call. The counter can "
"never go below zero; when :meth:`acquire` finds that it is zero, it blocks, "
"waiting until some task calls :meth:`release`."
#: library/asyncio-sync.rst:283
"The optional *value* argument gives the initial value for the internal "
"counter (``1`` by default). If the given value is less than ``0`` a :exc:"
"`ValueError` is raised."

"The preferred way to use a Semaphore is an :keyword:`async with` statement::"
#: library/asyncio-sync.rst:313
msgid "Acquire a semaphore."
#: library/asyncio-sync.rst:315
"If the internal counter is greater than zero, decrement it by one and return "
"``True`` immediately.  If it is zero, wait until a :meth:`release` is called "
"and return ``True``."

msgid "Returns ``True`` if semaphore can not be acquired immediately."
#: library/asyncio-sync.rst:325
"Release a semaphore, incrementing the internal counter by one. Can wake up a "
"task waiting to acquire the semaphore."

"``release()`` calls than ``acquire()`` calls."

msgstr "BoundedSemaphore"
#: library/asyncio-sync.rst:337
msgid "A bounded semaphore object.  Not thread-safe."
#: library/asyncio-sync.rst:339
"Bounded Semaphore is a version of :class:`Semaphore` that raises a :exc:"
"`ValueError` in :meth:`~Semaphore.release` if it increases the internal "
"counter above the initial *value*."
#: library/asyncio-sync.rst:352
"Acquiring a lock using ``await lock`` or ``yield from lock`` and/or :keyword:"
"`with` statement (``with await lock``, ``with (yield from lock)``) is "
"deprecated.  Use ``async with lock`` instead."
