This change resolves four issues:
PYTHON-826 The new codec_options submodule is moved from pymongo to bson.
PYTHON-827 Use codec_options in BSON APIs.
Functions and methods of the bson module that accepted the options as_class,
tz_aware, and uuid_subtype now accept a codec_options parameter instead.
For example, the function definition for bson.decode_all changes from this:
def decode_all(data, as_class=dict, tz_aware=True,
uuid_subtype=OLD_UUID_SUBTYPE)
to:
def decode_all(data, codec_options=CodecOptions())
The following functions are changed:
- decode_all
- decode_iter
- decode_file_iter
The following methods are changed:
- BSON.encode
- BSON.decode
This is a breaking change for any application that uses the BSON API directly
and changes any of the named parameter defaults. No changes are required for
applications that use the default values for these options. The behavior
remains the same.
PYTHON-828 Internal BSON module changes to support CodecOptions
The pure Python BSON module passes around a CodecOptions instance instead of
as_class, tz_aware, and uuid_subtype. C extensions pass these values around in
a struct.
PYTHON-801 Rename uuid_subtype to uuid_representation.
Replace MongoClient with an implementation that relies on Cluster and Server. The new MongoClient takes over MongoReplicaSetClient's responsibilities.
Authentication, secondary-pinning, and Mongos high-availability are broken and will be reimplemented in a future commit. RS tests are temporarily disabled.
The default binary subtype for UUIDs has changed
to 4. You can use bson.binary.UUIDLegacy to query
on UUIDs previously stored as subtype 3. See the
UUIDLegacy docstring for more details.
Many of the pymongo modules have been moved into the bson
package. Aliases for those modules have been added to the pymongo
package, without deprecation warnings for now. Application developers
should begin to use the bson namespace, as deprecation of moved
modules will probably begin in the next release.
