Revision history for DBIx::Class
+0.08250 2013-04-29 22:00 (UTC)
+ * New Features / Changes
+ - Rewrite from scratch the result constructor codepath - many bugfixes
+ and performance improvements (the current codebase is now capable of
+ outperforming both DBIx::DataModel and Rose::DB::Object on some
+ workloads). Some notable benefits:
+ - Multiple has_many prefetch
+ - Partial prefetch - you now can select only columns you are
+ interested in, while preserving the collapse functionality
+ (collapse is now exposed as a first-class API attribute)
+ - Prefetch of resultsets with arbitrary order
+ (RT#54949, RT#74024, RT#74584)
+ - Prefetch no longer inserts right-side table order_by clauses
+ (massively helps the deficient MySQL optimizer)
+ - Prefetch with limit on right-side ordered resultsets now works
+ correctly (via aggregated grouping)
+ - No longer order the insides of a complex prefetch subquery,
+ unless required to satisfy a limit
+ - Stop erroneously considering order_by criteria from a join under
+ distinct => 1 (the distinct should apply to the main source only)
+ - Massively optimize codepath around ->cursor(), over 10x speedup
+ on some iterating workloads.
+ - Support standalone \[ $sql, $value ] in literal SQL with bind
+ specifications: \[ '? + ?', 42, 69 ] is now equivalent to
+ \[ '? + ?', [ {} => 42 ], [ {} => 69 ] ]
+ - Changing the result_class of a ResultSet in progress is now
+ explicitly forbidden. The behavior was undefined before, and
+ would result in wildly differing outcomes depending on $rs
+ attributes.
+ - Deprecate returning of prefetched 'filter' rels as part of
+ get_columns() and get_inflated_columns() data
+ - Invoking get_inflated_columns() no longer fires get_columns() but
+ instead retrieves data from individual non-inflatable columns via
+ get_column()
+ - Emit a warning on incorrect use of nullable columns within a
+ primary key
+ - Limited checks are performed on whether columns without declared
+ is_nullable => 1 metadata do in fact sometimes fetch NULLs from
+ the database (the check is currently very limited and is performed
+ only on resultset collapse when the alternative is rather worse)
+
+ * Fixes
+ - Fix _dbi_attrs_for_bind() being called befor DBI has been loaded
+ (regression in 0.08210)
+ - Fix update/delete operations on resultsets *joining* the updated
+ table failing on MySQL. Resolves oversights in the fixes for
+ RT#81378 and RT#81897
+ - Fix open cursors silently resetting when inherited across a fork
+ or a thread
+ - Properly support "MySQL-style" left-side group_by with prefetch
+ - Fix $grouped_rs->get_column($col)->func($func) producing incorrect
+ SQL (RT#81127)
+ - Stop Sybase ASE storage from generating invalid SQL in subselects
+ when a limit without offset is encountered
+ - Even more robust behavior of GenericSubQuery limit dialect
+ - Make sure deployment_statements() and cursor_class() are called on
+ a resolved storage subclass
+
+ * Misc
+ - Fix tests failing due to unspecified resultset retrieval order
+ (test suite now will pass with newest SQLite libs)
+
+0.08210 2013-04-04 15:30 (UTC)
+ * New Features / Changes
+ - Officially deprecate the 'cols' and 'include_columns' resultset
+ attributes
+ - Remove ::Storage::DBI::sth() deprecated in 0.08191
+
+ * Fixes
+ - Work around a *critical* bug with potential for data loss in
+ DBD::SQLite - RT#79576
+ - Audit and correct potential bugs associated with braindead reuse
+ of $1 on unsuccessful matches
+ - Fix incorrect warning/exception originator reported by carp*() and
+ throw_exception()
+
+0.08209 2013-03-01 12:56 (UTC)
+ * New Features / Changes
+ - Debugging aid - warn on invalid result objects created by what
+ seems like an invalid inheritance hierarchy
+
+ * Fixes
+ - Fix another embarrassing regression preventing correct refining of
+ the search criteria on a prefetched relation (broken in 0.08205)
+ - Fix incorrect callsite reporting by DBIC::Carp
+
