Replace OP_INSERT/OP_UPDATE/OP_DELETE usage with OP_MSG with moreToCome
flag when the server is 3.6 or greater.
Unack'ed OP_MSG supports bypass_document_validation.
getLastError updatedExisting is always false on mongos after an OP_MSG
unack'ed update.
On Python 2, preallocate a bytearray and use slice assignment instead of
using str +=.
On Python 3, preallocate a bytearray and use a memoryview with recv_into.
Ordered op_insert should check for errors on the last insert.
Use _Bulk API for Collection.insert.
Avoid sending acknowledged inserts as much as possible.
max_cmd_size already accounts for trailing null bytes.
Use _OpReply class instead of passing bytes around.
Remove unnecessary operation argument to receive message.
Move _first_batch to message.py to avoid circular import.
Rename find_raw to find_raw_batches, and add aggregate_raw_batches.
Rename RawBSONCursor and RawBSONCommandCursor to RawBatchCursor and
RawBatchCommandCursor.
This commit add the pymongo.collation.Collation class and associated enums. A
collation may be sent with individual write operations when connected to MongoDB
3.4+. Unlike read and write concern, a collation may not be attached to a
database or collection instance.
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.
This commit implements the following simplifications and improvements:
- The Subscriber ABC has been renamed to CommandListener
- The subscribe function has been renamed to register
- The COMMAND constant has been removed
- The get_subscribers function has been removed
- Command listeners can now be registered per MongoClient instance
instead of just globally
