When encoding a document in C while running in a python sub interpreter
(e.g. mod_wsgi spawning sub interpreters) PyMongo would often have
to reload its cache of pure python types - ObjectId, Timestamp,
UUID, etc. - raising RuntimeWarning in the process. The reason this was
necessary is described in the mod_wsgi documentation here:
https://code.google.com/p/modwsgi/wiki/ApplicationIssues#Multiple_Python_Sub_Interpreters
With workarounds documented here:
http://api.mongodb.org/python/2.6.2/faq.html#does-pymongo-work-with-mod-wsgi
With this commit PyMongo will no longer use cached pure python types
when running in a sub interpreter. Instead it will look up pure python
types as needed (primarily when decoding BSON). This eliminates the
problem described in the mod_wsgi docs and eliminates the need for the
Runtime warning.
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.
