[Dbix-class] Announce: DBIx-Class-0.07

[Christopher H. Laco]

Fresh from the depths of the DBIx::Class repository, I'm happy to
announce the release of DBIx::Class 0.07. You can get it early at:

  http://pause.cpan.org/incoming/DBIx-Class-0.07000.tar.gz

It should be available on a CPAN mirror closest to you shortly.

Among the impressive list of fixes and changes, the most notable are:


  - Added InflateColumn::DateTime to auto create DateTime objects using
the appropriate DateTime::Format::* classin a database agnostic way

  - Added ResultSetColumn to perform aggregate and other functions on
specific resultset columns

  - Substantial refactor of ResultSet to to better handle more complex
joins and improve efficiency

  - Rewrite of many_to_many, including helpers for adding/deleting
objects without dealing with the link table directly



The following list of changes have been made since version 0.06003:

> - supress warnings for possibly non-unique queries, since
>     _is_unique_query doesn't infer properly in all cases
> - skip empty queries to eliminate spurious warnings on ->deploy
> - fixups to ORDER BY, tweaks to deepen some copies in ResultSet
> - fixup for RowNum limit syntax with functions
> - fix issue with from attr copying introduced in last release
> - documentation for new storage options, fix S::A::L hanging on to $dbh
> - substantial refactor of search_related code to fix alias numbering
> - don't generate partial unique keys in ResultSet::find() when a table
>     has more than one unique constraint which share a column and only one
>     is satisfied
> - cleanup UTF8Columns and make more efficient
>  - rename DBIX_CLASS_STORAGE_DBI_DEBUG to DBIC_TRACE (with compat)
>  - rename _parent_rs to _parent_source in ResultSet
>  - new FAQ.pod!
>  - fix issue with incorrect $rs->{attrs}{alias}
>  - fix subclassing issue with source_name
>  - tweak quotes test to output text on failure
>  - fix Schema->txn_do to not fail as a classmethod
>  - disable cdbi-t/02-Film.t warning tests under AS perl
>  - fixups to MySQL tests (aka "work round mysql being retarded")
>  - compat tweaks for Storage debug logging
>  - various documentation improvements
>  - fixes to pass test suite on Windows
>  - rewrote and cleaned up SQL::Translator tests
>  - changed relationship helpers to only call ensure_class_loaded when the
>      join condition is inferred 
> - rewrote many_to_many implementation, now provides helpers for adding
>      and deleting objects without dealing with the link table
> - reworked InflateColumn implementation to lazily deflate where
>      possible; now handles passing an inflated object to new()
> - changed join merging to not create a rel_2 alias when adding a join
>      that already exists in a parent resultset
> - Storage::DBI::deployment_statements now calls ensure_connected
>      if it isn't passed a type 
> - fixed Componentized::ensure_class_loaded
> - InflateColumn::DateTime supports date as well as datetime
> - split Storage::DBI::MSSQL into MSSQL and Sybase::MSSQL
> - fixed wrong debugging hook call in Storage::DBI 
> - set connect_info properly before setting any ->sql_maker things 
> - Fixed up POD::Coverage tests, filled in some POD holes
> - Added a warning for incorrect component order in load_components
> - Fixed resultset bugs to do with related searches
> - added code and tests for Componentized::ensure_class_found and
>     load_optional_class
> - NoBindVars + Sybase + MSSQL stuff
> - only rebless S::DBI if it is still S::DBI and not a subclass
> - Added `use' statement for DBD::Pg in Storage::DBI::Pg
> - stopped test relying on order of unordered search
> - bugfix for join-types in nested joins using the from attribute
> - obscure prefetch problem fixed
> - tightened up deep search_related
> - Fixed 'DBIx/Class/DB.pm did not return a true value' error
> - Revert change to test for deprecated find usage and swallow warnings
> - Slight wording change to new_related() POD
> - new specific test for connect_info coderefs
> - POD clarification and content bugfixing + a few code formatting fixes
> - POD::Coverage additions
> - fixed debugfh
> - Fix column_info stomping
> - add automatic naming of unique constraints
> - marked DB.pm as deprecated and noted it will be removed by 1.0
> - add ResultSetColumn
> - refactor ResultSet code to resolve attrs as late as possible
> - merge prefetch attrs into join attrs
> - add +select and +as attributes to ResultSet
> - added InflateColumn::DateTime component
> - refactor debugging to allow for profiling using Storage::Statistics
> - removed Data::UUID from deps, made other optionals required
> - modified SQLT parser to skip dupe table names
> - added remove_column(s) to ResultSource/ResultSourceProxy
> - added add_column alias to ResultSourceProxy
> - added source_name to ResultSource
> - load_classes now uses source_name and sets it if necessary
> - add update_or_create_related to Relationship::Base
> - add find_or_new to ResultSet/ResultSetProxy and find_or_new_related
>      to Relationship::Base
>  - add accessors for unique constraint names and coulums to
>      ResultSource/ResultSourceProxy
> - rework ResultSet::find() to search unique constraints
> - CDBICompat: modify retrieve to fix column casing when ColumnCase is
>      loaded
> - CDBICompat: override find_or_create to fix column casing when
>      ColumnCase is loaded
> - reorganized and simplified tests
> - added Ordered
> - added the ability to set on_connect_do and the various sql_maker
>     options as part of Storage::DBI's connect_info.



Happy coding and enjoy!
