Revision history for DBIx::Class
0.08240-TRIAL (EXPERIMENTAL BETA RELEASE) 2013-02-14 05:56 (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)
- Massively optimize codepath around ->cursor(), over 10x speedup
on some iterating workloads.
* Fixes
- Fix open cursors silently resetting when inherited across a fork
or a thread
- Fix duplicated selected columns when calling 'count' when a same
aggregate function is used more than once in a 'having' clause
(RT#83305)
* Misc
- Fixup our distbuilding process to stop creating world-writable
tarball contents (implicitly fixes RT#83084)
- Added strict and warnings tests for all lib and test files
0.08206 2013-02-08
* Fixes
- Fix dbh_do() failing to properly reconnect (regression in 0.08205)
- Extra sanity check of a fresh DBI handle ($dbh). Fixes
connection coderefs returning garbage (seen in the wild)
* Misc
- Only allow known globals in SQL::Translator leak allowance
- General cleanup of error message texts - quote names/identifiers
for easier reading
- Stop t/52leaks.t from failing when AUTOMATED_TESTING=1
0.08205 2013-01-22
* New Features / Changes
- The emulate_limit() arbitrary limit dialect emulation mechanism is
now deprecated, and will be removed when DBIx::Class migrates to
Data::Query
- Support for the source_bind_attributes() storage method has been
removed after a lengthy deprecation cycle
* Fixes
- When performing resultset update/delete only strip condition
qualifiers - leave the source name alone (RT#80015, RT#78844)
- Fix incorrect behavior on resultset update/delete invoked on
composite resultsets (e.g. as_subselect_rs)
- Fix update/delete operations referencing the updated table failing
on MySQL, due to its refusal to modify a table being directly
queried. As a workaround induce in-memory temp-table creation
(RT#81378, RT#81897)
- More robust behavior under heavily threaded environments - make
sure we do not have refaddr reuse in the global storage registry
- Fix failing test on 5.8 under Win32 (RT#81114)
- Fix hash-randomization test issues (RT#81638)
- Disallow erroneous calling of connect_info on a replicated storage
(RT#78436)
* Misc
- Improve the populate docs in ::Schema and ::ResultSet
- ::Storage::DBI::source_bind_attributes() removed as announced
on Jan 2011 in 0e773352a
0.08204 2012-11-08
* New Features / Changes
- SQLMaker now accepts \'literal' with the 'for' rs attribute as an
override to the builtin FOR options
* Fixes
- Fix unique constraint violations in Ordered.pm blanket movement
(RT#79773, rolls back short-sighted 5e6fde33e)
- Fix API mismatch between new_result() and new_related() (originally
broken by fea3d045)
- Fix test failure on perl 5.8
* Misc
- Much more extensive diagnostics when a new RDBMS/DSN combination is
encountered (RT#80431)
0.08203 2012-10-18
* Fixes
- Really fix inadequate $dbh->ping SQLite implementation (what shipped
in 0.08201 tickled other deficiencies in DBD::SQLite itself)
0.08202 2012-10-06
* Fixes
- Replace inadequate $dbh->ping SQLite implementation with our own,
fixes RT#78420
0.08200 2012-08-24 (UTC)
* Fixes
- Change one of the new tests for the previous release to not require
SQL::Translator
0.08199 2012-08-22 (UTC)
* Fixes
- Roll back incomplete (and broken) internal changes - restore prefetch functionality
0.08198 2012-07-11 03:43 (UTC)
* Fixes
- Fix a number of Win32 Test issues
- Fix silent Oracle connection failures
0.08197 2012-07-10 10:32 (UTC)
* New Features / Changes
- Issue a warning when DateTime objects are passed to ->search
- Fast populate() in void context is now even more efficient by
going directly through execute_for_fetch bypassing execute_array
- Fix update()/delete() on complex resultsets to no longer fall back
to silly row-by-row deletion, construct a massive OR statement
instead
- Allow complex update/delete operations on sources without a
primary key, as long as they have at least one non-nullable
unique constraint
- dbicadmin now better supports catalyst-style config files, by
unrolling 'config_info' hashkeys
- Multiple Improvements MSSQL over DBD::ADO
- Transaction support
- Support for VARCHAR(MAX)/VARBINARY(MAX)/NVARCHAR(MAX) datatypes
- Nomalization of retrieved GUID values
* Fixes
- Fix complex has_many prefetch with resultsets not selecting identity
columns from the root result source
- Fix SkipFirst and FirstSkip limit dialects (Informix and Firebird)
- Fix "Skimming limit" dialects (Top, FetchFirst) to properly check
the order_by criteria for stability
- Fix "Skimming limit" dialects (Top, FetchFirst) to propagate
non-selected order criteria when part of a larger subquery
- Fix RowNumberOver and all "skimming limits" to correctly assemble
bind values when supplied for both select and order_by
- Fix all subquery-based dialects to not lose a subquery fragment
when we both select and order by the result of the same subquery
- Fix the Sybase hubrid limit dialect (RowCountOrGenericSubQ) losing
Group/Having/Order clauses when called without an offset (RT#73244)
- No longer generate incorrect SQL on ->as_query called on resultsets
with software_limit enabled
- A number of corner case fixes of void context populate() with \[]
- Fix corner case of forked children disconnecting the parents DBI
handle
- Improve identity/autoinc retrieval code in MSSQL and Sybase -
should reduce weird side-effects especially with populate()
- Explicitly disable DBD::ODBC batch operations (as of DBD::ODBC 1.35)
for the following drivers too buggy to handle the optimized path:
- FreeTDS ODBC driver (when used with MSSQL)
- The Firebird ODBC driver
- The MSAccess ODBC driver
- Explicitly disable DBD::ODBC dynamic_cursors when using freetds 0.83
or later - they made enough ODBC incompatible changes making it
impossible to support sanely
- Explicitly disable SCOPE_IDENTITY queries and statement caching for
MSSQL on DBD::Sybase compiled against freetds 0.83 or later - way too
buggy
- Disable statement caching when using Sybase ASE and DBD::Sybase
compiled against freetds 0.83 or later
- Fix leakage of $schema on in-memory new_related() calls
- Fix more cases of $schema leakage in SQLT::Parser::DBIC
- Fix leakage of $storage in ::Storage::DBI::Oracle
- Fix pessimization of Oracle RowNum limit dialect query when no
offset has been specified
- Remove useless vestigial pessimization in Ordered.pm for cases
when the position column is part of a unique constraint
- Fix dbicadmin to no longer ignore the documented 'config' option
- The schema-resultsource entanglement is now much more robust
under threads
- Fix ::Schema::ddl_filename() failing miserably on paths containing
certain numeric sequences
- t/53lean_startup.t adjusted for new 5.15.x base.pm behavior
* Misc
- Centralized leak-checks for all instances of DBICTest::Schema
from within any test
