"""**(Provisional)** Apply the given timeout for a block of operations.
|
||||
|
||||
.. note:: :func:`~pymongo.timeout` is currently provisional. Backwards
|
||||
incompatible changes may occur before becoming officially supported.
|
||||
|
||||
Use :func:`~pymongo.timeout` in a with-statement::
|
||||
|
||||
with pymongo.timeout(5):
|
||||
client.db.coll.insert_one({})
|
||||
client.db.coll2.insert_one({})
|
||||
|
||||
When the with-statement is entered, a deadline is set for the entire
|
||||
block. When that deadline is exceeded, any blocking pymongo operation
|
||||
will raise a timeout exception. For example::
|
||||
|
||||
try:
|
||||
with pymongo.timeout(5):
|
||||
client.db.coll.insert_one({})
|
||||
time.sleep(5)
|
||||
# The deadline has now expired, the next operation will raise
|
||||
# a timeout exception.
|
||||
client.db.coll2.insert_one({})
|
||||
except PyMongoError as exc:
|
||||
if exc.timeout:
|
||||
print(f"block timed out: {exc!r}")
|
||||
else:
|
||||
print(f"failed with non-timeout error: {exc!r}")
|
||||
|
||||
When nesting :func:`~pymongo.timeout`, the nested deadline is capped by
|
||||
the outer deadline. The deadline can only be shortened, not extended.
|
||||
When exiting the block, the previous deadline is restored::
|
||||
|
||||
with pymongo.timeout(5):
|
||||
coll.find_one() # Uses the 5 second deadline.
|
||||
with pymongo.timeout(3):
|
||||
coll.find_one() # Uses the 3 second deadline.
|
||||
coll.find_one() # Uses the original 5 second deadline.
|
||||
with pymongo.timeout(10):
|
||||
coll.find_one() # Still uses the original 5 second deadline.
|
||||
coll.find_one() # Uses the original 5 second deadline.
|
||||
|
||||
:param seconds: A non-negative floating point number expressing seconds, or None.
|
||||
|
||||
:raises: :py:class:`ValueError`: When `seconds` is negative.
|
||||
|
||||
