MongoDB

Changes for version v0.999.998.5 - 2015-04-30

*** Deprecations ***
- MongoDB::CommandResult changed the name of the accessor for the document returned by the server to 'output' instead of 'result' for clarity. The 'result' method is deprecated.
Changes
- Generic MongoDB::Error exceptions have been replaced with subclasses that have a specific, documented purpose, including: MongoDB::AuthError, MongoDB::GridFSError, MongoDB::InternalError and MongoDB::UsageError.
- Calls to Carp::confess() or die() have been replaced with exceptions from MongoDB::Error subclasses, typically MongoDB::UsageError.
- Failure to create indexes when constructing a GridFS object are ignored rather than a fatal error.
- Now includes a longer list of default OS locations to search for root CA files.

Changes for version v0.999.998.4 - 2015-03-25 (TRIAL RELEASE)

*** Deprecations ***
- Legacy MongoDB::Collection CRUD methods (insert, update, etc.) have been deprecated in favor of new CRUD API methods
- PERL-507 MongoDB::Collection::get_collection is deprecated; it implied subcollections, which don't actually exist
Additions
- PERL-502|PERL-503 Implement new common driver CRUD API in MongoDB::Collection
Bug fixes
- PERL-480 retrieving a GridFS file now throws an error if no chunks exist instead of returning an empty string
- Suppressed warning about "Can't locate package MongoDB::WriteResult" from MongoDB::BulkWriteResult::ISA
- Fixed incorrect 'matched_count' result attribute for upserts
- Ensure topology type is correct whenever a server is marked unavailable
Changes
- MongoDB::Collection attributes that should not be set in the constructor have been made private, but with public accessors for backwards compatibility. Private attributes that are set in the constructor (e.g. 'database') are now public.
Documentation
- PERL-464 Documented deprecation of 'last_error'
- PERL-510 Documented MongoDB::QueryResult
- Improved docs for MongoDB::Error with info on exported error codes
- Clarified docs for MongoDB::Collection::get_collection
Removals
- PERL-497 The $MongoDB::BSON::use_boolean never worked; BSON boolean values were always deserialized as boolean.pm objects. Rather than "fix" this and break people's code, the option has been removed and documented as such.

Changes for version v0.999.998.3 - 2015-03-25 (TRIAL RELEASE)

Broken upload due to TLS bugs

Changes for version v0.999.998.2 - 2015-02-23 (TRIAL RELEASE)

!!! Incompatible Changes !!!
- MongoClient read_preference attribute is now immutable
- Renamed WriteResult to BulkWriteResult
*** Deprecations ***
- PERL-464 Deprecated the 'last_error' Database method
Additions
- PERL-93 implemented awaitData
- PERL-135 added ability to set write_concern at db and collection level
- PERL-259 implemented write commands for MongoDB 2.6+ (i.e. doing writes via database commands versus via the wire protocol with OP_INSERT, OP_UPDATE, etc.)

Bug Fixes

- Fixed t/database.t for change in server error message
- Fixed use of slave_ok and $readPreference for communicating read preferences to a mongos

- Requires at least Path::Tiny 0.054 (rather than unspecified)
- Removed core modules File::Copy, File::Path and File::Spec from the list of test dependencies
- Removed Class::MOP::Class as an explicit dependency (still used internally by Moose)
