It's not safe to return the pinned connection to the pool from within
Cursor.del because the Pool's lock may be held by a python thread
while the cyclic garbage collector runs. Instead we send the cursor
cleanup request to the client's background thread. The thread will
send killCursors on the pinned socket and then return the socket to
the pool.
Also fixed a similar bug when garbage collecting a pinned session.
This change removes the u() helper from bson.py3compat
and all of its uses in the driver and tests. PyPy3 continues
to be supported since, even though it is based on python 3.2.5,
it has always supported the u string prefix.
The README and install docs are now explicit about PyPy(3) support.
- Changed parameter names (default values and behaviors remain the same):
- spec (spec_or_id in find_one) -> filter
- fields -> projection
- partial -> allow_partial_results
- The "timeout" option is renamed to "no_cursor_timeout" with its default
changed to False.
- The tailable, await_data, and exhaust options will be replaced with a
cursor_type option. Valid values:
- cursor.NON_TAILABLE
- cursor.TAILABLE
- cursor.TAILABLE_AWAIT
- cursor.EXHAUST
- The following options are added:
- oplog_replay (bool - default False) - only valid with tailable cursors
against the oplog.
- modifiers (document - default None) - A dict of query modifiers. See
http://docs.mongodb.org/manual/reference/operator/query-modifier/#modifiers for
options.
- The following options are removed, replaced by the "modifiers" option:
- max_scan
- snapshot
- The as_class option is removed. Use Collection.with_options instead.
