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.
+ - Change func_rs() and as_subselect_rs() to properly ignore list
+ context (i.e. wantarray). Both were implemented broken from day 1 :/
+ - 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
+ - search() calls with an empty select list are deprecated. While DBIC
+ will still issue a SELECT * ..., it now warns given there is nothing
+ higher up in the stack prepared to interpret the result
* 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)
+ - 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/ )
+ - A new low-level API for relationship resolution is available as an
+ official method ( $rsrc->resolve_relationship_condition ). This is
+ mainly of interest to builders of reflection tools
+ - 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
- - Ensure failing on_connect* / on_disconnect* are dealt with properly,
- notably on_connect* failures now properly abort the entire connect
+ - 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 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 spurious warning on MSSQL cursor invalidation retries (RT#102166)
+ - Fix incorrect ::Storage->_ping() behavior under Sybase (RT#114214)
+ - Fix some corner cases of non-fatal failures during relationship
+ resolution showing up as hard errors
- Fix several corner cases with Many2Many over custom relationships
- - Fix t/52leaks.t failures on compilerless systems (RT#104429)
- - Fix t/105view_deps.t failing with libsqlite >= 3.009, where view
- definitions are lazily-checked for correctness only at DML-time as
- opposed to DDL-time (RT#1546088)
- - Fix t/storage/quote_names.t failures on systems with specified Oracle
- test credentials while missing the optional Math::Base36
- - Fix the Sybase ASE storage incorrectly attempting to retrieve an
- autoinc value when inserting rows containing blobs (GH#82)
- - Fix test failures when DBICTEST_SYBASE_DSN is set (unnoticed change
- in error message wording during 0.082800 and a bogus test)
+ - 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)
- - Protect tests and codebase from incomplete caller() overrides, like
- e.g. RT#32640
- - Work around rare test deadlock under heavy parallelism (RT#108390)
- 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'

+
+ * 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)
