- Move ReturnDocument to pymongo.collection.
- Change ReturnDocument.Before to ReturnDocument.BEFORE
- Change ReturnDocument.After to ReturnDocument.AFTER
- Add pymongo.cursor.CursorType.
- Move pymongo.cursor.NON_TAILABLE and friends to attributes of CursorType.
- read_preferences.ReadPreference is once again an "enum".
- Fix docs for read_preferences.ReadPreference.
- Rename pymongo.options to pymongo.operations.
- Export CursorType, ReturnDocument, WriteConcern, and public classes
from pymongo.opertions through pymongo/__init__.py
- Fix up a number of documentation issues in the process.
Database.command no longer obeys Database.read_preference or
Database.codec_options. Explicit parameters have been added
for both options. See the ticket for a full explanation.
Replace 5-sample moving average with exponentially weighted average,
required by the upcoming Server Selection Spec. Move responsibility for
tracking the average from ServerDescription to Monitor. Now the
ServerDescription only knows the average at the time it was created.
MongoClient now supports all MongoReplicaSetClient's features.
Fix bugs and add features in the new MongoClient to bring it up
to spec. MongoReplicaSetClient is now a deprecated stub that
subclasses MongoClient.
Introduce new errors, NetworkTimeout and NotMasterError, to
communicate events that MongoClient must handle specially.
This commit does a few things:
- Adds tag_sets back (deprecated)
- Adds secondary_acceptable_latency_ms back (deprecated)
- Makes acceptable latency a per read preference setting
- Cleans up read preference instance generation
- Adds latencyThresholdMS as an alias for secondaryAcceptableLatencyMS.
The name may change before 3.0 is released.
This commit introduces the following changes:
- Each read preference is now a class.
- Read preferences other than Primary accept a tag_sets parameter.
- The tag_sets attribute of MongoClient, Database, and Collection has
been removed. Use the tag_sets parameter of the new classes instead.
- The read_preferences.ReadPreference constant still exists and should
continue to work as expected for most users.
