Revision history for Perl extension DBIx::Abstract.

1.006 2005-04-23

• Fixed a bug discovered by Jan Martin Mathiassen <reaper@mindriot.as>. If you pass in a password but no username it's supposed to ignore the password. Instead it was clearing it in the hash that you passed in but still using it.
• Removed Test::More and Test::Builder from the distribution-- put Test::Simple in the prerequisites.

1.005 2003-03-14 -- The "I broke the build and install process" release

• Fixed a stupid problem where Test::Builder and Test::More would be installed by this package. Ack.
• Made the Makefile.PL default to not providing a database driver. Tests will be skipped if you do this. (This way automated module testing won't break when it shouldn't.)
• Added a dependency on Scalar::Util.

1.004 2003-02-17

• ensure_connection did not work correctly if DBI was set to die on errors.
• Back ported test suite and makefile from 1.1. Back ported patch to fix mysqlPP compatibility issues.
• Made clone weaken references it takes so that it won't leak memory. Added memory leak test.
• A bug fix relating to select_one_ and select_all_ where if the query failed and returned undef, the routine would crash. This is now fixed and it just propagates the undef.

1.003 2002-09-23

• Fixed Win32 bug found by Kanji T Bates.
• Connect for oracle can look a bit more like those for other DBD drivers now. You may now specify your SID in the dbname field.

1.002 2001-09-05

• Fixed bug introduced in 1.001 where trying to read ->opt always produced undef.

1.001 2001-09-05

• Made it so that opt can now take any DBI attribute.

1.000 2001-09-04

• Now produces a better error that config/DSN is not defined.
• When the DBIx::Abstract object is destroyed it usually closes any associated database handles (if it's the last clone alive), now it will only do this if it created the handle. This way, if you pass in a handle it will survive its use by DBIx::Abstract.

0.96 2001-07-07

• Fixed stupid bug that made it not accept DBI handles. I can't believe I actually took eight months to check this in.

0.95 2000-11-12

• Changed how CVSVERSION and LAST_CHANGE are calculated.
• Made it so that you can pass routines literal strings instead of variables (variables are used with bind_params when possible) by passing a scalar reference.
• I also allow array references to do this (in some circumstances) but this is deprecated.
• Made connect optionally accept DBI handles instead of connection info, by recommendation of Mark Stosberg <mark@summersault.com>.
• Changed how self was obtained to be (IMHO) stylistically better.

0.94 2000-08-04

• Removed an annoying warn that only shows up unpredictably. I think it has to do with Perls garbage collection not working the way I thought it worked. Meanwhile I may have fixed the undocumented dataseek method. But probably not.
• Made it so that updates and inserts can produce nulls, eg: $dbh->update('foo',{bar=>undef}); Would set the 'bar' column to NULL.
• Fixed tyop, s/STOCK TRACE/STACK TRACE/g.
• Made connected method safer. It won't crash if the DBI handle is invalid or non-existent.

0.93 2000-04-17

• Fixed a problem with cloning. Clones other then the first clone were getting a copy of the clone list. This caused unexpected calls to the classes DESTROY method. This produced warnings, but there shouldn't have been any errors.

0.921 2000-04-07

• Well I managed to check in the last version without including the bug fix.
• Added select_one_to_array and select_one_to_arrayref.
• Fixed a nasty little bug involving CLONES. It had been failing to register clones of clones. This was causing a memory leak.

0.920 2000-04-07

• Added ability to inserts with literal values.

0.910 2000-03-31

• Fixed bug in make test that caused it to fail when a password was needed for testing. This didn't effect me as my database accepts anonymous connections to the test database over loopback.
• Fixed some warnings when username or password were undefined.

0.900 2000-03-03

• Changed name to DBIx::Abstract in preparation for addition to CPAN.
• Updated README to be accurate regarding the current version.
• Fixed a bug where an empty where would produce invalid SQL.
• Changed version to reflect the fact that it is VERY close to being ready for 1.0.

0.079 2000-03-03

• Fixed a bug where an empty where would produce invalid SQL.
• Fixed a bug that caused death under S

0.078 2000-02-18

• Added 'saveSQL' option which, with each query, stuffs the generated SQL into the 'lastsql' key in the self payload.
• Changed logging code for sql to log a single string (with quoted parameters) instead of a string with ?'s and a bind_params array.

0.07.7 2000-01-19

• Fixed some memory leaks (these were only a problem if you were creating SQL::DBI objects in a loop).
• Moved from test.pl to t/basic.t for better testing.

0.07.6 1999-12-29

• Another dumb bug... tried calling __logwrite before I had actually created the SQL::DBI object.

0.07.5 1999-12-21

• Found stupid bug where if you called a statement handle specific method before doing a query (and creating one) it would crash. Normally I would shrug my shoulders and say "Don't be dumb", but it is handy to be able to call "finish" regardless.

0.07.4 1999-12-09

• Made select_one_to_hashref and select_all_to_hashref accept the same parameters as select.
• Made select accept both table and tables, as well as field and fields.

0.07.3 1999-12-03

• Fixed bug Mike <michael@mint.net> found in the new special happy join syntax. Maybe I should have tested it. Created more bugs, then fixed those too.

0.07.2 1999-11-02

• Fixed the bug JasonJ <kyroraz@jmac.org> found. The connected and the reconnect methods were failing due to a call to logwrite (the real method name is __logwrite). I've also added tests for this to the 'make test'.
• Added "join" and "group" params to select. This allows group bys and easier joins.

0.07.1 1999-07-28

• Made it so that wheres can have arrays nested in them.
• Added code to make where generation code easier to debug.

0.07.0 1999-06-25

• Changed version numbering system so that I can have major and minor releases more easily.
• Fixed a warning in select about a twice 'my'ed variable, thanks Jmac.
• Fixed a bug that stopped people from passing a DBI data_source to connect.
• Fixed logging to include @bind_params.
• Added warnings to test
• Changed all doubled quoted strings that didn't need to be double quoted single quotes.
• Changed connect to log if it fails to connect. Improved die if SQL::DBI is unable to create a data source.
• Added method ``connected''. It returns true if dbh->{'Active'} is true.
• Added method ``reconnect''. Reconnects if this object has been connected before.
• Added method ``ensure_connection''. Ensures that the object is connected and that the connection is valid (by doing a ``SELECT 1''). Tries to reconnect if it isn't connected. Dies if it is unable to provide a connection.
• Changed select so that table is optional. That is, db->select(1) will produce ``SELECT 1'' instead of ``SELECT 1 FROM''
• Updated documentation to reflect that loglevel 0 is used for fatal errors.

0.06 1999-04-23

• Fixed documentation where it used "is like" instead of "like".
• Modified all routines to use bind_params instead of 'quote'. This should only effect users in positive ways, if at all.
• Changed connect to use 'dbname' instead of 'db' for compatibility with ODBC. This change won't break legacy code: If you use 'db' it will be renamed to 'dbname' for you.
• Changed DEFAULT connect type to simply generate an arbitrary data_source based on the config hash you pass. So if you pass: { driver=>'foo', bar=>'baz', blat='bar' } Your data_source will be dbi:foo:bar=baz;blat=bar

0.05 1999-03-23

• Added "kill kill kill" and "die die die" as per jak's suggestion.
• Changed "kill kill kill" and "die die die" to all caps as per jmac's suggestion.
• Added a few, undocumented "Mysql" compatibility functions
• Made insert, replace and update accept scalars as well as hashses for all of their parameters.
• Documented the new alternative interface for passing all parameters.
• Fixed bug in changes file... 0.03 and 0.04 were listed with the wrong dates.

0.04 1999-02-26

• Added commit and rollback pass throughs.
• Added 'AutoCommit' option which works like DBH hash value, with one difference: It will warn instead of die if you give it an invalid value.
• Added DESTROY method. Now handles finish and disconnect calls on its own.

0.03 1999-02-23

• Changed method of selecting the DBI datasource, should be easier to add new datasources now.
• Now allows the datasource to be passed in as a scalar (for databases not explicitly supported). This should allow this module to work with any database supported by DBI.
• Now stores all of the information used to create the DBI connection just in case we need it later.
• Changed fetchrow_hash to return values the same way Mysql->fetchhash does. This should stop 'while(%hash=$db->fetchrow_hash)' constructs from breaking.
• Added dataseek function. Currently this is only useful with the mysql driver, which is why it isn't documented yet. Hopefully something like this is available with the other database drivers, however if it isn't then i will remove it. (So don't use it yet!)
• Removed undocumented "join" feature of select. It was possible to do it without an extra feature.
• Made all functions accept hashes as well as parameter lists. This will be reaching the documentation in the next release, once it's a bit more polished.

0.02a 1999-01-20

• Argh. Made it so that you can actually do a 'make install'. (Broke with change to SQL::DBI.)

0.02 1999-01-14

• Changed name to SQL:DBI from Shashou.

0.01 1999-01-06

• Built a proper package for the module using h2xs
• Moved change log to 'Changes' file.
• Added the ability to support drivers other then MySQL. Now has PostgreSQL support.

0.00 1999-01-05

• Added CHANGE LOG section.
• Started versioning (version 0.0)
• Moved PERLDOC section to bottom
• Made methods return $self my default
• Improved examples
