Revision history for DBIx::Class

    * Notable Changes and Deprecations
        - The entire class hierarchy now explicitly sets the 'c3' mro, even
          in cases where load_components was not used. Extensive testing led
          the maintainer believe this is safe, but this is a very complex
          area and reality may turn out to be different. If **ANYHTING** at
          all seems out of place, please file a report at once
        - The unique constraint info (including the primary key columns) is no
          longer shared between related (class and schema-level) ResultSource
          instances. If your app stops working with no obvious pointers, set
          DBIC_ASSERT_NO_ERRONEOUS_METAINSTANCE_USE=1 to obtain extra info
        - Neither exception_action() nor $SIG{__DIE__} handlers are invoked
          on recoverable errors. This ensures that the retry logic is fully
          insulated from changes in control flow, as the handlers are only
          invoked when an error is leaving the DBIC internals to be handled by
          the caller (n.b. https://github.com/PerlDancer/Dancer2/issues/1125)
          (also fixes the previously rejected RT#63874)
        - Overrides of ResultSourceProxy-provided methods are no longer skipped
          silently: a one-per-callsite warning is issued any time this tricky
          situation is encoutered https://is.gd/dbic_rsrcproxy_methodattr
        - $result->related_resultset() no longer passes extra arguments to
          an underlying search_rs(), as by design these arguments would be
          used only on the first call to ->related_resultset(), and ignored
          afterwards. Instead an exception (detailing the fix) is thrown.
        - Increased checking for the correctness of the is_nullable attribute
          within the prefetch result parser may highlight previously unknown
          mismatches between your codebase and data source
        - Calling the set_* many-to-many helper with a list (instead of an
          arrayref) now emits a deprecation warning
        - Calling the getter $rsrc->from("argument") now throws an exception
          instead of silently discarding the argument

    * New Features
        - DBIC now performs a range of sanity checks on the entire hierarchy
          of Schema/Result/ResultSet classes loudly alerting the end user to
          potential extremely hard-to-diagnose pitfalls ( RT#93976, also fully
          addresses https://blog.afoolishmanifesto.com/posts/mros-and-you/ )
        - InflateColumn::DateTime now accepts the ecosystem-standard option
          'time_zone', in addition to the DBIC-only 'timezone' (GH#28)
        - Massively optimised literal SQL snippet scanner - fixes all known
          slowdowns ( in some cases 50x ) of very complex prefetch/selects
        - DBIx::Class::Optional::Dependencies now properly understands
          combinations of requirements and does the right thing with e.g.
          ->req_list_for([qw( rdbms_oracle ic_dt )]) bringing in the Oracle
          specific DateTime::Format dependencies

    * Fixes
        - Fix regresion (0.082800) of certain calls being presented stale
          result source metadata (RT#107462)
        - Fix incorrect SQL generated with invalid {rows} on complex resultset
          operations, generally more robust handling of rows/offset attrs
        - Fix silent failure to retrieve a primary key (RT#80283) or worse:
          returning an incorrect value (RT#115381) in case a rdbms-side autoinc
          column is declared as PK with the is_auto_increment attribute unset
        - Fix incorrect $storage state on unexpected RDBMS disconnects and
          other failure events, preventing clean reconnection (RT#110429)
        - Make sure exception objects stringifying to '' are properly handled
          and warned about (GH#15)
        - Fix incorrect data returned in a corner case of partial-select HRI
          invocation (no known manifestations of this bug in the field, see
          commit message for description of exact failure scenario)
        - Fix corner case of stringify-only overloaded objects being used in
          create()/populate()
        - Fix spurious warning on MSSQL cursor invalidation retries (RT#102166)
        - Fix incorrect ::Storage->_ping() behavior under Sybase (RT#114214)
        - Fix several corner cases with Many2Many over custom relationships
        - Fix intermittent failure to infer the CASCADE attributes of relations
          during deployment_statements()/deploy()
        - Fix corner cases of C3 composition being broken on OLD_MRO (5.8.x)
          only: https://github.com/frioux/DBIx-Class-Helpers/issues/61

    * Misc
        - Add explicit test for pathological example of asymmetric IC::DT setup
          working with copy() in t/icdt/engine_specific/sybase.t (GH#84)
        - Fix t/54taint.t failing on local::lib's with upgraded Carp on 5.8.*
        - Fix invalid variable names in ResultSource::View examples
        - Fix missing ORDER BY leading to failures of t/prefetch/grouped.t
          under upcoming libsqlite (RT#117271)
        - Skip tests in a way more intelligent and speedy manner when optional
          dependencies are missing
        - Make the Optional::Dependencies error messages cpanm-friendly
        - Incompatibly change values (not keys) of the hash returned by
          Optional::Dependencies::req_group_list (no known users in the wild)
        - Stop using bare $] throughout - protects the codebase from issues
          similar (but likely not limited to) P5#72210
        - Config::Any is no longer a core dep, but instead is migrated to a new
          optdep group 'config_file_reader'

0.082840 2016-06-20 07:02 (UTC)
    * New Features
        - When using non-scalars (e.g. arrays) as literal bind values it is no
          longer necessary to explicitly specify a bindtype (this turned out
          to be a mostly useless overprotection)

    * Fixes
        - Ensure leaving an exception stack via Return::MultiLevel or something
          similar produces a large warning
        - Another relatively invasive set of ::FilterColumn changes, covering
          potential data loss (RT#111567). Please run your regression tests!
        - Ensure failing on_connect* / on_disconnect* are dealt with properly,
          notably on_connect* failures now properly abort the entire connect
        - Fix use of ::Schema::Versioned combined with a user-supplied
          $dbh->{HandleError} (GH#101)
        - Fix parsing of DSNs containing driver arguments (GH#99)
        - Fix silencing of exceptions thrown by custom inflate_result() methods
        - Fix complex prefetch when ordering over foreign boolean columns
          ( Pg can't MAX(boolcol) despite being able to ORDER BY boolcol )
        - Fix infinite loop on ->svp_release("nonexistent_savepoint") (GH#97)
        - Fix spurious ROLLBACK statements when a TxnScopeGuard fails a commit
          of a transaction with deferred FK checks: a guard is now inactivated
          immediately before the commit is attempted (RT#107159)
        - Fix the Sybase ASE storage incorrectly attempting to retrieve an
          autoinc value when inserting rows containing blobs (GH#82)
        - Remove spurious exception warping in ::Replicated::execute_reliably
          (RT#113339)
        - Work around unreliable $sth->finish() on INSERT ... RETURNING within
          DBD::Firebird on some compiler/driver combinations (RT#110979)
        - Fix leaktest failures with upcoming version of Sub::Quote
        - Really fix savepoint rollbacks on older DBD::SQLite (fix in 0.082800
          was not sufficient to cover up RT#67843)

    * Misc
        - Test suite is now officially certified to work under very high random
          parallelism: META x_parallel_test_certified set to true accordingly
        - Typo fixes from downstream debian packagers (RT#112007)

0.082821 2016-02-11 17:58 (UTC)
    * Fixes
        - Fix t/52leaks.t failures on compilerless systems (RT#104429)
        - Fix t/storage/quote_names.t failures on systems with specified Oracle
          test credentials while missing the optional Math::Base36
        - Fix test failures when DBICTEST_SYBASE_DSN is set (unnoticed change
          in error message wording during 0.082800 and a bogus test)
        - Remove largely obsolete test of SQLite view deployment (RT#111916)

    * Misc
        - Work around rare test deadlock under heavy parallelism (RT#108390)

0.082820 2015-03-20 20:35 (UTC)
    * Fixes
        - Protect destructors from rare but possible double execution, and
          loudly warn the user whenever the problem is encountered (GH#63)
        - Relax the 'self_result_object' argument check in the relationship
          resolution codepath, restoring exotic uses of inflate_result
          http://lists.scsys.co.uk/pipermail/dbix-class/2015-January/011876.html
        - Fix updating multiple CLOB/BLOB columns on Oracle
        - Fix exception on complex update/delete under a replicated setup
          http://lists.scsys.co.uk/pipermail/dbix-class/2015-January/011903.html
        - Fix uninitialized warnings on empty hashes passed to join/prefetch
          https://github.com/vanstyn/RapidApp/commit/6f41f6e48 and
          http://lists.scsys.co.uk/pipermail/dbix-class/2015-February/011921.html
        - Fix hang in t/72pg.t when run against DBD::Pg 3.5.0. The ping()
          implementation changes due to RT#100648 made an alarm() based
          timeout lock-prone.

    * Misc
        - Remove warning about potential side effects of RT#79576 (scheduled)
        - Various doc improvements (GH#35, GH#62, GH#66, GH#70, GH#71, GH#72)
        - Depend on newer Moo, to benefit from a safer runtime (RT#93004)
        - Fix intermittent failures in the LeakTracer on 5.18+
        - Fix failures of t/54taint.t on Windows with spaces in the $^X
          executable path (RT#101615)

0.082810 2014-10-25 13:58 (UTC)
    * Fixes
        - Fix incorrect collapsing-parser source being generated in the
          presence of unicode data among the collapse-points
        - Fix endless loop on BareSourcelessResultClass->throw_exception(...)

    * Misc
        - Depend on newer SQL::Abstract (fixing overly-aggressive parenthesis
          opener: RT#99503)
        - Depend on newer Moo, fixing some interoperability issues:
          http://lists.scsys.co.uk/pipermail/dbix-class/2014-October/011787.html

0.082801 2014-10-05 23:55 (UTC)
    * Known Issues
        - Passing large amounts of objects with stringification overload
          directly to DBIx::Class may result in strange action at a distance
          exceptions. More info (and a workaround description) can be found
          under "Note" at https://metacpan.org/pod/SQL::Abstract#is_plain_value
        - The relationship condition resolution fixes come with the side effect
          of returning more complete data, tripping up *some* users of an
          undocumented but widely used internal function. In particular
          https://rt.cpan.org/Ticket/Display.html?id=91375#txn-1407239

    * 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
        - find() now throws an exception if some of the supplied values are
          managed by DBIC::FilterColumn (RT#95054)
        - 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)
        - Deprecate { col1 => col2 } expressions in manual {from} structures
          (at some point of time manual {from} will be deprecated entirely)

    * 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 collapse being ignored on single-origin selection (RT#95658)
        - Fix incorrect behavior on custom result_class inflators altering
          the amount of returned results
        - 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
        - Proper exceptions on malformed relationship conditions (RT#92234)
        - Fix incorrect handling of custom relationship conditions returning
          SQLA literal expressions
        - Fix long standing bug with populate() missing data from hashrefs with
          different keysets: http://is.gd/2011_dbic_populate_gotcha (RT#92723)
        - 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_column on non-native (+columns) selections (RT#86685)
        - Fix set_inflated_column incorrectly handling \[] literals (GH#44)
        - Ensure that setting a column to a literal invariably marks it dirty
        - Fix copy() not working correctly with extra selections present
        - Work around exception objects with broken string overloading in one
          additional codepath (missed in 0.08260)
        - Fix more inconsistencies of the quote_names attribute propagating
          to SQL::Translator (partially RT#87731)
        - Fix SQLT constraint naming when DBIC table names are fully qualified
          (PR#48)
        - Ensure ::Schema::Versioned connects only once by reusing the main
          connection (GH#57)
        - 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

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)

          primary key, as long as they have at least one non-nullable
          unique constraint

          is not ordered by a unique column
        - Revert "Fix incorrect signature of the default sqlt_deploy_hook"
          from 0.08191 - documentation was in fact incorrect, not the code

          with new default format expected by DateTime::Format::Sybase)
        - Fix a bug in update_all() resulting in the first row receiving a

          column value instead of just autoinc primary keys
        - Bring back strict ordering of selectors in complex search chains
          (an ill-fated attempt was made in 0.08127 to order intelligently)
        - All limit dialects (except for the older Top and FetchFirst) are
          now using bind parameters for the limits/offsets, making DBI's
          prepare_cached useful across paged resutsets

        - Disable mysql_auto_reconnect for MySQL - depending on the ENV
          it sometimes defaults to on and causes major borkage on older
          DBD::mysql versions

          the "root" columns are in fact injected from the right rs side
        - Fix the join optimizer to correctly preserve the non-multi path to
          a multi relationship ( x -> might_have y -> has_many z )

          with multilevel monikers (e.g. $schema->source('Foo::Bar') )
        - Fix incorrect signature of the default sqlt_deploy_hook - it now
          matches the documentation of passing in the result source object
        - Fix inadequate handling of internal storage methods within
          ::Storage::Replicated (RT#66295)

        - Switch to a warning when find() is invoked with both a 'key'
          argument and a NULL-containing condition to satisfy the named
          constraint. Previously (starting with 0.08124) an exception was
          thrown
        - Switch to a warning when a commit is attempted with an out-of-sync
          transaction_depth (someone issued a begin externally to DBIC).

        - New method ResultSource columns_info method, returning multiple
          pairs of column name/info at once
        - $rs->search now throws when called in void context, as it makes
          no sense (and is nearly always a sign of a bug/misdesign)
        - Restore long-lost ability to supply unbalanced select/as pairs
          e.g. +select => \'DISTINCT(foo, bar)', +as => ['foo', 'bar']
        - +columns now behaves just like columns by not stripping a
          fully-qualified 'as' spec (i.e. foo.bar results in $obj->foo->bar)
        - Deprecate legacy $rs->search( %condition ) syntax (warn once per
          callsite)

        - add_unique_constraint() now poparly throws if called with
          multiple constraint definitions
        - No longer depend on SQL::Abstract::Limit - DBIC has been doing
          most of the heavy lifting for a while anyway
        - FilterColumn now passes data through when transformations
          are not specified rather than throwing an exception.
        - Optimized RowNum based Oracle limit-dialect (RT#61277)
        - Requesting a pager on a resultset with cached entries now
          throws an exception, instead of returning a 1-page object
          since the amount of rows is always equal to the "pagesize"
        - $rs->pager now uses a lazy count to determine the amount of
          total entries only when really needed, instead of doing it
          at instantiation time

          due to badly-written handlers (the mechanism was never meant
          to be able to suppress exceptions)

        - Temporarily fixed 5.13.x failures (RT#58225)
          (perl-core fix still pending)
        - Fix result_soutrce_instance leaks on compose_namespace
        - Fix $_ volatility on load_namespaces (a class changing $_
          at compile time no longer causes a massive fail)

        - Skip a test that breaks due to serious bugs in current DBD::SQLite
        - Fix tests related to leaks and leaky perls (5.13.5, 5.13.6)

    * Misc

          (RNO, Top, RowNum) to be much more robust wrt complex joined
          resultsets
        - MSSQL limits now don't require nearly as many applications of
          the unsafe_subselect_ok attribute, due to optimized queries
        - Support for Generic Subquery limit "emulation" - awfully slow
          and inefficient but works on almost any db, and is preferred
          to software limit emulation
        - Sybase ASE driver now uses SET ROWCOUNT where possible, and
          Generic Subquery otherwise for limit support instead of always

          default value insert is requested (RT#28875)
        - Make IC::DT extra warning state the column name too
