Revision history for DBIx::Class
* Notable Changes and Deprecations
- $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.
- Calling the set_* many-to-many helper with a list (instead of an
arrayref) now emits a deprecation warning
* New Features
- 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 corner case of stringify-only overloaded objects being used in
create()/populate()
- Fix several corner cases with Many2Many over custom relationships
- 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
* Misc
- 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)
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

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
- 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)

{ col => { -ident => 'othercol' } } vs { col => \'othercol' }
- Extend 'proxy' relationship attribute
- Use DBIx::Class::Storage::Debug::PrettyPrint when the
environment variable DBIC_TRACE_PROFILE is set, see
DBIx::Class::Storage for more information
- Implemented add_unique_constraints() which delegates to
add_unique_constraint() as appropriate
- 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
- New documentation map organized by features
(DBIx::Class::Manual::Features)
- find( { ... }, { key => $constraint } ) now throws an exception
when the supplied data does not fully specify $constraint
- find( col1 => $val1, col2 => $val2, ... ) is no longer supported
(it has been in deprecated state for more than 4 years)
- Make sure exception_action does not allow exception-hiding
due to badly-written handlers (the mechanism was never meant
to be able to suppress exceptions)
* Fixes

- Temporarily fixed 5.13.x failures (RT#58225)
(perl-core fix still pending)
- Fix result_soutrce_instance leaks on compose_namespace

$ordered_rs->search_related ('has_many_rel') resultsets
- Oracle sequence detection now *really* works across schemas
(fixed some ommissions from 0.08123)
- dbicadmin now uses a /usr/bin/env shebang to work better with
perlbrew and other local perl builds

(RT#59619)
- Fixed t/54taint fails under local-lib
- Fixed SELECT ... FOR UPDATE with LIMIT regression (RT#58554)
- Fixed CDBICompat to preserve order of column-group additions,
so that test relying on the order of %{} will no longer fail
- Fixed mysterious ::Storage::DBI goto-shim failures on older
perl versions
- Non-blessed reference exceptions are now correctly preserved
when thrown from udner DBIC (e.g. from txn_do)
- No longer disconnecting database handles supplied to connect
via a coderef

on DateTime::Format::Pg (RT#61503)
- Fix dirtyness detection on source-less objects
- Fix incorrect limit_dialect assignment on Replicated pool members
- Fix invalid sql on relationship attr order_by with prefetch
- Fix primary key sequence detection for Oracle
(first trigger instead of trigger for column)
- Add various missing things to Optional::Dependencies
- Skip a test that breaks due to serious bugs in current DBD::SQLite

- Makefile.PL no longer imports GetOptions() to interoperate
better with Catalyst installers
- Bumped minimum Module::Install for developers
- Bumped DBD::SQLite dependency and removed some TODO markers
from tests (RT#59565)
- Do not execute t/zzzzzzz_sqlite_deadlock.t for regular module
installs - test is prone to spontaneous blow up
- DT-related tests now require a DateTime >= 0.55 (RT#60324)
- Makefile.PL now provides a pre-parsed DBIC version to the
Opt::Dep pod generator
- t/52leaks.t now performs very aggressive leak detection in
author/smoker mode
0.08123 2010-06-12 14:46 (UTC)
* Fixes
- Make sure Oracle identifier shortener applies to auto-generated
column names, so we stay within the 30-char limit (RT#58271)
- Oracle sequence detection now works across schemas
- Fix a Storage/$dbh leak introduced by the migration to
Try::Tiny (this is *not* a Try::Tiny bug)
- Fix corner case of count with group-by over a 1:1 join column
where the selector ends up with column name clashes
- POD fixes (RT#58247)
* Misc
- Test suite default on-disk database now checks for Win32
fail-conditions even when running on other OSes
0.08122 2010-06-03 17:41 (UTC)
* New Features
- Add DBIx::Class::FilterColumn for non-ref filtering
- ::Storage::DBI now correctly preserves a parent $dbh from
terminating children, even during interpreter-global
out-of-order destruction
- dbicadmin supports an -I option with the same semantics as
perl itself
- InflateColumn::DateTime support for MSSQL via DBD::Sybase
- Millisecond precision support for MSSQL datetimes for
InflateColumn::DateTime
- Oracle-specific hierarchical query syntax support:
CONNECT BY (NOCYCLE) / START WITH / ORDER SIBLINGS BY

- current_source_alias method on ResultSet objects to
determine the alias to use in programatically assembled
search()es (originally added in 0.08100 but unmentioned)
- Rewrite/unification of all subselecting limit emulations
(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
using software limit emulation
- create_ddl_dir (and derivatives) now attempt to create the given
$ddl_dir if it does not already exist
- deployment_statements now automatically supplies the current RDBMS
version to SQLT producer_args for MySQL, Pg, SQLite and Oracle
* Fixes
- Fix nasty potentially data-eating bug when deleting/updating
a limited resultset
- Fix find() to use result_class set on object
- Fix result_class setter behaviour to not mistakenly stuff attrs.
