It is my pleasure to announce the beta release of mongo-c-driver 1.5.0-rc3.

New features and bug fixes:

  • MongoDB 3.4 Support
    -- * MaxStalenessMS
    -- * MongoDB Handshake
  • mongoc_collection_count_with_opts uses the collection's read preference if
    -- none is passed in
  • Improved TLS support
    -- * Fixed LibreSSL (libssl) support
    -- * Added LibreSSL (libtls) support
    -- * Fixed Secure Channel build on VS 2010
    -- * OpenSSL now supports SNI (all others already do)
  • Additional features for Application Performance Monitoring:
    -- * mongoc_topology_description_has_writable_server
    -- * mongoc_topology_description_has_readable_server
  • New command functions accept flexible options as a BSON document:
    -- * mongoc_client_read_command_with_opts
    -- * mongoc_client_write_command_with_opts
    -- * mongoc_client_read_write_command_with_opts
    -- * mongoc_database_read_command_with_opts
    -- * mongoc_database_write_command_with_opts
    -- * mongoc_database_read_write_command_with_opts
    -- * mongoc_collection_read_command_with_opts
    -- * mongoc_collection_write_command_with_opts
    -- * mongoc_collection_read_write_command_with_opts
  • New helper function to include read concern in one of the above function's
    -- options parameter: mongoc_read_concern_append.
  • mongoc_client_command no longer applies the client's read preference and
    -- read concern by default. Same change for mongoc_database_command and
    -- mongoc_collection_command.
  • mongoc_collection_count_with_opts now applies the collection's read
    -- preference if no read preference is provided
  • mongoc_collection_create_index and mongoc_collection_drop_index now apply
    -- the collection's write concern.
  • mongoc_collection_create_index_with_opts now applies the collection's
    -- write concern if none is specified in "opts"
  • connectTimeoutMS timer now begins after DNS resolution, and resets
    -- for each interface attempted (e.g., if the driver first tries IPv6,
    -- then IPv4).
  • New error code MONGOC_ERROR_DUPLICATE_KEY.
  • mongoc_collection_find no longer treats the "filter" key specially in
    -- queries - querying for a document with a key named "filter" is the same
    -- now as any other key.
  • The server description parameter to the following functions is "const":
    -- * mongoc_server_description_host
    -- * mongoc_server_description_id
    -- * mongoc_server_description_ismaster
    -- * mongoc_server_description_round_trip_time
    -- * mongoc_server_description_type
  • Exported symbols are no longer declared in seperate export files.
    -- This could break ABI with applications using clang, which previously
    -- exported symbols from the internal private ABI.
  • mongoc no longer crashes when multi roundtrip bulk operation fails.
  • Added support for the new readConcernLevel "linearizable".
  • Clients now check for misformatted "readPreferenceTags" in URI.
  • New CMake option ENABLE_TRACING allows debug output, which before had only
    -- been available with "configure --enable-tracing".
  • Bugfix: "PossiblePrimary"-type replicas could be selected for reads
  • The random number generator used to select servers is now properly seeded.
  • mongoc_collection_insert, mongoc_collection_update, mongoc_collection_remove
    -- consistently use domain MONGOC_ERROR_BSON, code MONGOC_ERROR_BSON_INVALID
    -- if passed oversized BSON, and MONGOC_ERROR_COLLECTION for other errors.
    -- mongoc_bulk_operation_execute continues to use MONGOC_ERROR_COMMAND for
    -- all errors.

Removed configure flags:

  • --enable-experimental has been removed. All previously experimental
    -- features are now always on.
  • The configure option "--enable-hardening" had had no effect. It is removed
    -- in favor of system-wide compiler configuration.

Thanks to everyone who contributed to the development of this release.
