Allow drivers that wrap PyMongo to add their info to the handshake
metadata, using a "driver" option like:
MongoClient(driver=DriverInfo("MyDriver", "1.2.3"))
The DriverInfo is appended to PyMongo's own metadata.
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.
Wherever possible set:
- keep-alive idle time to a maximum of 300 seconds.
- keep-alive interval time to a maximum of 10 seconds.
- keep-alive count to a maximum of 9 probes.
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
If ssl=True is passed as a keyword arg (or ssl=true in the URI)
but no value for ssl_cert_reqs or ssl_ca_certs has been provided,
assume ssl.CERT_REQUIRED for cert_reqs and attempt to load
system provided CA certificates. Raise ConfigurationError if
the necessary SSLContext methods don't exist.
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.
And use them in place of UUID_SUBTYPE and OLD_UUID_SUBTYPE. This
change also cleans up and clarifies the documentation for
JAVA_LEGACY and CSHARP_LEGACY. None of these are binary subtypes,
but instead UUID representations in the Python, C#, and Java drivers.
