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.
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.
Add retryWrites MongoClient and URI setting.
Retry once for supported single-statement write operations including:
insert_one, update_one, delete_one, find_one_and_update, find_one_and_replace,
find_one_and_delete, update and remove with multi=False, and find_and_modify.
The server no longer includes process id when generating
ObjectIds so we can't actually test that the _id value
was generated by the server instead of the driver.
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.
The min_wire_version and max_wire_version attributes have
always been racy when connected to a mixed version replica set
or any sharded cluster. When connected to a mongos all you know
is the wire version of that mongos, not the shards behind it.
With mongos load balancing this problem is even worse, since
each operation could possibly be executed on a different mongo
version during an upgrade.
- Deprecate ensure_index
- Remove caching from create_index
- In create_index, remove support for the cache_for param, and the
bucket_size and drop_dups aliases (they all remain in ensure_index)
- GridFS uses create_index
- Fix up tests.
With this change the max_pool_size named parameter to
MongoClient is removed. It is replaced by the maxPoolSize
MongoDB URI option, which can be passed in a URI, or as a
keyword argument to MongoClient.
This commit deprecates insert, update, save, and remove. Each
now raises DeprecationWarning at stacklevel 2. This change also
updates all tutorials and example documentation to use the new
CRUD API, tests the deprecations, and fixes up a few more tests
that were still using the legacy API.
