Revision history for Class-AutoDB

1.27_02	2013-09-29
	No functional changes
	Updated depdendencies
        Fixed boilerplate & pod tests
	Added 000.reqs test to check existence MySQL database, adapted from Babel
        Removed Developer tests from distro.  Haven't been tested in a while!

1.27_01	2013-07-28
	Bug fixes
	- connect was using the wrong property name when setting 'socket' in
	  dsn. was using 'sock'; should be 'mysql_socket'
	Changes to tests
	 - regression test for socket bug
	 - updated 002.pod to strip development sub-version number
	 - imported 003.manifest from Babel

1.26	2012-11-29
	Changes to tests
	- fixed the change made in 1.25.  $^V, the variable containing Perl's
	  version, works differently in different versions. in perls > 5.10 it
	  returns a regular string, while in earlier versions it returns a 
	  v-string. naturally, the code to handle these cases is different...

1.25	2012-11-28
	Changes to tests
	- tests of DOES method now check for Perl version >= 5.10.1, since that
	  is when DOES was added to UNIVERSAL. thanks to the CPAN smoke testers
	  for finding this problem! 

1.24	2012-10-28
	Added test for version number in POD
	Removed redundant 'dist_version_from' param from Build.PL
	Bug fixes
	- when invoking a UNIVERSAL method (isa, can, DOES, VERSION) on Oid or
	  OidDelelted, the method was not redispatched to the real class

1.23    2012-08-02
	Changed code and tests to correct deprecated use of qw(...) as parentheses
	Changes to Build.PL
	- added Module::Build to configure_requires
        - added dist_version_from

1.22	2011-01-07
	Bug fixes
	- when 'using' a class at runtime, schema changes were not happening;
	  the common failure case was a class loaded at runtime that defines
	  a collection
	Changes to Build.PL
	- added explicit test for DBD::mysql based on code in Data::Babel's
	  Build.PL and removed from prereqs. it doesn't work to put in prereqs
	  because if not present, install tries to install 'DBD' which does not 
	  exist
	Changes to tests
	- declare.030.pct_autodb.t was not setting 'create' flag in call to
	  'new'. longstanding bug that remained undetected because previous
	  tests left the database in a state that didn't bother it

1.21	2011-01-05
	Bug fixes;
	- when deleting objects whose classes were not yet 'used', the deletes 
	  were not being applied to the objects' collections; this was because
	  the class-to-collection information was set in the registry

1.20	2010-09-20
        New features
	- 'del' method to delete objects
        - queries ('get', 'find', 'count') with no arguments retrieve/count all
	  objects. makes it possible to retrieve objects without defining
	  collections
	- raw SQL can be used in queries ('get', 'find', 'count')
        Bug fixes
	- drop views everywhere that we drop tables, so views will not get in
	  way when we create tables. (arises because DROP TABLE only drops 
	  tables, not views)
	Many small cleanups in code and tests

1.19_02 2010-09-17
 	Bug fixes
	- added 'numify' to overloads in Oid and OidDeleted. arises because
	  Perls >= 5.10 use stringify to autogenerate numify
	  (Thanks to CPAN testers for finding this!)
	- found a few more places where I drop tables and now have to also
	  drop views
	Changes to tests
	- added code to emit MySQL version in 000.code_exists test
	- check MySQL version in 150.dropview test and skip if version too
	  old to support views
	- added tests for overloaded numify

1.11	2010-03-08
	Changes to build and test process only.
	Changes to Build.PL:
	- added DBD, DBI::mysql, plus some others to configure_requires. thanks 
	  to CPAN testers for finding this problem
	Changes in tests:
	- more screwing around with MySQL's max_allowed_packet variable. this
	  limits the size of the biggest object that can be stored. I have come
	  to learn that setting this variable has no effect, even though the
	  MySQL documentation claims that it is a session variable. recent
	  versions of the docs correct this misconception...

1.10	2010-03-01
	Brings CPAN version up-to-date with version used internally at ISB
        New features:
        - 'put' method added to AutoDB (in Class::AutoDB::Database) to store
           specific objects. this is a step towards cleaning up namespace of
           user-objects
        - 'oid' method added to AutoDB. this is a step towards cleaning up 
          namespace of user-objects
	- %AUTODB=0 works
	- %AUTODB with HASH form of keys: type defaults to string, as it does
	  with all other forms
	- 'port' and 'timeout' added to connection parameters
	Cleanup:
	- connection management (connect, reconnect, etc) made consistent
	- 'renew' made consistent with 'new'
        Bug fixes:
	- in perl 5.10, '==' comparison in AutoDB::put was forcing stringify when
	  applied to Oids. fixed by moving '==' after check for Oid.
        - 'exists' (in Class::AutoDB::Database) now checks for empty
          _AutoDB table; this may address common problem where AutoDB
          appears to exists, but registry does not exist
	- fixed ambiguity of ‘get’ (AutoClass::get was masking AutoDB::get)
	  by changing order of base classes; this is short term workaround --
          really need to clean up AutoClass namespace!
	- 'store' (in Class::AutoDB::Serialize) was using wrong regex when
	  processing transients: /$key/ insead of /^$key$/. This caused keys to 
	  be ignored if they matched any substring of a transient. 
	  Scary this wasn't caught earlier!!
	- 'count' was throwing exception when count was 0. Scary this wasn't
	  caught earlier!!
        - 'put' was storing undef in base table when value of key was 0. Does
	  not impact the actual objects returned by 'get' (since objects stored
	  in _AutoDB), but breaks queries selecting on 0. Scary this wasn't
	  caught earlier!!
	- queries on lists with duplicate values were returning duplicate
	  objects
	- queries with multiple terms addressing the same list key were ignoring
	  all but one of the terms
	- queries with multiple terms addressing the same scalar key now
	  detected as illegal
	- objects with incorrectly typed search keys now behave predictably
	- queries with undef values now do 'IS NULL'
        - keys declared with abbreviated types were not always being seen as
	  equivalent (eg, 'int' vs. 'integer'
	- programmatic definition of collections now works
	Changes to Build process
	- added Tie::ToObject to prereqs
	- changes to Build.PL for better handling of MySQL dependency. not sure 
	  either of these are necessary or even help...
	- added DBD::mysql to prereqs
	- put DBI->connect inside eval to catch error when DBD::mysql not
	  installed
	- removed Dumper.o from distro tarball
	Bug fixes in tests:
	- changed 'note' to 'diag' in several tests to get more information
	  from testers
	- fixed simple coding error in autodb.122.bad_freeze.t ('dbh' to '$dbh')
        - return aggregate in t::Build::run_tap_harness (overrides method from
	  Module::Build) as new versions of Module::Build require this
	- in autodb.010.putget.t, now invoke perl via full (secure) path rather
	  than just 'perl'
	- in graph.020 tests, skip tests unless max_allowed_packet big enough
	  (long term solution added to release 1.20 plan)
	- in bad_freeze tests, skip tests unless max_allowed_packet big enough
	  (long term solution added to release 1.20 plan)

0.1     06-01-04
	- in Oid, added code to 'use' classes when object is fetched
          if not already 'used'. caution: this only works if people
          follow the Perl convention of placing module Foo in file
          Foo.pm.  Else, there's no easy way to translate a classname
          into a string that can be 'used'
	- in Oid, added overload for stringification and a few related
          op. stringify fetches object, so serialized objects will
          work as expected when used as hash key
	- in Object, added overload declaration for objects after
          they've been fetched.  don't know why this is needed, but it
          didn't work without it
	- in Serialize, made -transients work
	- changed syntax of %AUTODB declaration to allow multiple
          collections to be specified with different keys. backwards
          compatible. affects code in Collection, Oid, Registration,
          Registry, RegistryVersion

0.092	05-10-25
          data source might be wrong (evil and silent bug)
	- added SQL limit capability to AutoDB, users can now pass a
          _limit_ => n, where n=max number of rows to fetch, in find
          args

0.091   05-06-08
	- Added option to turn off automatic indexing
	The following defects have been addressed (see also bug tracker at 
        www.sf.net project: isbiology):
	  1216645 added "pass" synonym per feature request

0.09  2004/20/10
	- optimized patch courtesy of Jenda of perl monks
	- find now handles multiple collections in query

0.08  Wed Sep  1 14:09:29 PDT 2004
	The following defects have been addressed (see also bug tracker at 
        www.sf.net project: isbiology):
         1016244 no persistence on (enclosed) test
         1016246 reformat of list sorage
         1019348 not all objects stored
         1016242 create flag not working for registry
         1016238 _registry_is_saved error
         1017046 not all objects stored

0.07  Tue Aug 17 10:52:27 PDT 2004
	- require 5.8.2 added for perl version, manifest rebuilt to include patch files 

0.06  Mon Aug 16 14:24:43 PDT 2004
	- major refactor of persistence handling. store() method added to store 
          objects explicitly (implicit storage still occurs when an object is 
          destroyed. Implicitly destroyed objects will not overwrite explicitly 
          destroyed ones). Mosts tests have been re-written and new ones have been 
          added to test this storage handling.
	
0.05  17 May 2004
	- refactor of reconstitution code
	
0.04  Mon Feb 23 11:15:53 PST 2004
	- refactored tests so that tests that need a DB connection skip if DB 
          connection is not negotiated

0.03  Thu Feb 19 09:46:40 PST 2004
	- refactored: database connection is now made at runtime

0.02  Tues Jan 06 17:01:12 PST 2004
	- some code cleanup, documentation changes 

0.01  Mon Dec 22 17:28:49 PST 2003
	- original version.
