Revision history for DBIx::Class
+ * Notable Changes and Deprecations
+ - DBIC::FilterColumn now properly bypasses \'' and \[] literals, just
+ like the rest of DBIC
+ - DBIC::FilterColumn "from_storage" handler is now invoked on NULLs
+ returned from storage
+ - Custom condition relationships are now invoked with a slightly
+ different signature (existing coderefs will continue to work)
+ - Add extra custom condition coderef attribute 'foreign_values'
+ to allow for proper reverse-relationship-like behavior
+ (i.e. $result->set_from_related($custom_rel, $foreign_result_object)
+ - When in a transaction, DBIC::Ordered now seamlesly handles result
+ objects that went out of sync with the storage (RT#96499)
+ - CDBICompat::columns() now supports adding columns through supplied
+ Class::DBI::Column instances (GH#52)
+
+ * Fixes
+ - Fix Resultset delete/update affecting *THE ENTIRE TABLE* in cases
+ of empty (due to conditions) resultsets with multi-column keys
+ - Fix on_connect_* not always firing in some cases - a race condition
+ existed between storage accessor setters and the determine_driver
+ routines, triggering a connection before the set-cycle is finished
+ - Fix failure to detect stable order criteria when in iterator
+ mode of a has_many prefetch off a search_related chain
+ - Prevent erroneous database hit when accessing prefetched related
+ resultsets with no rows
+ - Fix incorrect handling of custom relationship conditions returning
+ SQLA literal expressions
+ - Fix long standing bug with populate() getting confused by hashrefs
+ with different sets of keys: http://is.gd/2011_dbic_populate_gotcha
+ - Fix multi-value literal populate not working with simplified bind
+ specifications
+ - Massively improve the implied resultset condition parsing - now all
+ applicable conditions within a resultset should be properly picked
+ up by create() and populate()
+ - Ensure definitive condition extractor handles bizarre corner cases
+ without bombing out (RT#93244)
+ - Fix set_inflated_column incorrectly handling \[] literals (GH#44)
+ - Ensure that setting a column to a literal invariably marks it dirty
+ - Work around exception objects with broken string overloading in one
+ additional codepath (missed in 0.08260)
+ - Fix inability to handle multiple consecutive transactions with
+ savepoints on DBD::SQLite < 1.39
+ - Fix CDBICompat to match Class::DBI behavior handling non-result
+ blessed has_a (implicit deflate via stringification and inflate via
+ blind new) (GH#51)
+
+ * Misc
+ - Ensure source metadata calls always take place on the result source
+ instance registered with the caller
+ - IFF DBIC_TRACE output defaults to STDERR we now silence the possible
+ wide-char warnings if the trace happens to contain unicode
+ - Remove ::ResultSource::resolve_condition - the underlying machinery
+ is in flux, and the method has had a deprecation warning for 5 years
+
+0.08270 2014-01-30 21:54 (PST)
+ * Fixes
+ - Fix 0.08260 regression in DBD::SQLite bound int handling. Inserted
+ data was not affected, but any function <=> integer comparison would
+ have failed (originally fixed way back in 0e773352)
+ - Fix failure to load DateTime formatter when connecting to Firebird
+ over ODBC
+
+ * Misc
+ - All drivers based on ::Storage::DBI::Firebird::Common now return the
+ same sqlt_type value (affects ::DBI::Interbase, ::DBI::Firebird and
+ ::DBI::ODBC::Firebird)
+
+0.08260 2014-01-28 18:52 (UTC)
+ * New Features
+ - A new zero-to-DBIC style manual: DBIx::Class::Manual::QuickStart
+
+ * Notable Changes and Deprecations
+ - Explicitly deprecate combination of distinct and selecting a
+ non-column via $rs->get_column()
+
+ * Fixes
+ - More robust handling of circular relationship declarations by loading
+ foreign classes less frequently (should resolve issues like
+ http://lists.scsys.co.uk/pipermail/dbix-class/2013-June/011374.html)
+ Note that none of this is a manifestations of a DBIC bug, but rather
+ unexpected (but correct) behavior of load-order-dependent (hence
+ logically broken) Resultclass hierarchies. In order to deal with this
+ DBIC is scaling back a large number of sanity checks, which are to be
+ reintroduce pending a better framework for source registration
+ - Fix multiple edge cases of complex prefetch combining incorrectly
+ with correlated subquery selections
+ - Fix multiple edge cases stemming from interaction of a non-selecting
+ order_by specification and distinct and/or complex prefetch
+ - Fix unbound growth of a resultset during repeated execute/exhaust
+ cycles (GH#29)
+ - Work around (and be very vocal about the fact) when DBIC encounters
+ an exception object with broken string overloading
+ - Clarify ambiguous behavior of distinct when used with ResultSetColumn
+ i.e. $rs->search({}, { distinct => 1 })->get_column (...)
+ - Setting quote_names propagates to SQL::Translator when producing
+ SQLite DDL (it is one of the few producers *NOT* quoting by default)
+ - Fix incorrect binding of large integers on old versions of
+ DBD::SQLite (now DBIC simply always binds SQLite ints as BIGINT)
+ - Silence (harmless) warnings on recent DBD::SQLite versions, when
+ inserting/updating large integers on 32bit ivsize systems (RT#76395)
+ - Back out self-cleaning from DBIx::Class::Carp for the time being
+ (as a side effect fixes RT#86267)
+ - Fix incorrect internal use of implicit list context in copy()
+ - Fix 0.08250 regression in driver determination when DBI_DSN is used
+ - Tests no longer fail if $ENV{DBI_DSN} is set
+ - Throw clearer exception on ->new_related() with a non-existent
+ relationship
+ - Fix incorrect parethesis unroll with multicolumn in, (never noticed
+ before fixing false positive in SQLA::Test 1.77)
+ - Fix t/storage/replicated.t class loading problem
+ - Stop using the deprecated Class::MOP::load_class()
+ - Fix warning in t/54taint.t with explicitly unset PERL5LIB (RT#91972)
+ - Fix t/54taint.t failing under a local::lib with installed earlier
+ DBIC version (RT#92486)
+
+ * Misc
+ - Massive incompatible change of ::BlockRunner internals (was never
+ documented as usable externally, this last set of changes settles
+ the design for proper documentation and opening up)
+ - Adjust exceptions in tests to accommodate changes in the upcoming
+ DBD::SQLite based on libsqlite 3.8.2
+ - More robust lock file naming scheme - allow tests to work on exotic
+ MSWin32 filesystems (habitual offender being http://is.gd/iy5XVP)
+ - Better diagnostics when File::Spec->tmpdir gives us crap in testing
+ - Replace $row with $result in all docs to be consistent and to
+ clarify various return values
+
+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
- - Stop erroneously considering order_by criteria from a join under
- distinct => 1 (the distinct should apply to the main source only)
- - Even more robust behavior of GenericSubQuery limit dialect
+ - 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
- - Correctly recognize root source unqualified columns when
- resolving right-side ordered limited prefetch
+ - 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)
