DbFramework change log
2021-02-08
1. The DbFramework is hosted on GitHub now.
2. MANIFEST.SKIP: Added.
3. Makefile, MANIFEST, META.yml, SIGNATURE, t/Config.pm: Removed
the generated files.
4. COPYING: Removed the redundant and irrelevant GPL license copy.
5. AUTHORS, TODO, README, README.md: Replaced the messy
GNU-styled documents with a single Markdown README.md.
2008-05-03
1. Makefile.PL and Build.PL: Automatic checks and lists only
the available DBD drivers for tests.
2008-05-03 version 1.12
1. Makefile.PL and Build.PL: Provide a valid default DSN for
DBD::mysql, DBD::mSQL and DBD::Pg.
2. Makefile.PL and Build.PL: Do not create the schema if
answer is "no".
2008-04-21
1. Changes: Updated.
2. Build.PL: Renamed test database from "dbframework_test" to
"test", to adapt the convention of MySQL and PostgreSQL.
3. TODO: Added.
4. AUTHORS: Added.
5. Artistic and COPYING: Added.
6. Makefile.PL: Added PL_FILES to disable PL files searching
behavior, in order to work with ExtUtils::MakeMaker earlier
than 6.25 that treats Build.PL as one of the PL files to run.
2008-04-20
1. Added lib and lib/DbFramework subdirectory. Move everything
inside, to make the directory cleaner.
2. Makefile.PL: Clean up. Removed PMLIBDIRS since it is not
required anymore. Removed linkext. linkext is only needed
for ExtUtils::MakeMaker before version 5. That is too old
today.
3. Makefile.PL and Build.PL: Use "use lib qw(lib);
use DbFramework::Util;" instead of "require "./Util.pm"", in
order to be more portable on different platforms.
4. Makefile.PL: Renamed test database from "dbframework_test" to
"test", to adapt the convention of MySQL and PostgreSQL.
5. README: Moved Paul's BackPen URL to the previous line.
2008-04-19
1. Added lib and lib/DbFramework subdirectory. Move everything
inside, to make the directory cleaner.
2. Changes: Added, with contents from original Paul's README file.
This is to adapt the Perl module convention.
2008-04-19 version 1.11
Maintenance taken over by imacat.
1. Makefile.PL: Updated to use prompt() from ExtUtils::MakeMaker
instead of reading STDIN directly, in order to prevent infinite
loop with automated CPAN testers. (RT#34538)
2. t/util.pl: Subroutine yn() removed. It is not used anymore,
due to the prompt() fix.
3. README: Add notice about the distribution ownership change.
4. Makefile.PL: ABSTRACT, AUTHOR, LICENSE and SIGN added to the
WriteMakefile() arguments. VERSION is added in replace of
VERSION_FROM.
5. SIGNATURE: Digital signature added.
6. META.yml: YAML distribution meta-information added.
7. Build.PL: Module::Build build support added.

==================================
History
=======
15-05-1999 Paul Sharpe <paul@miraclefish.com>
--------------------------------------------------------------------
RELEASE 1.10
Added support for PostgreSQL.
INTERFACE CHANGES
PrimaryKey::
- New method as_hidden_html()
30-04-1999 Paul Sharpe <paul@miraclefish.com>
--------------------------------------------------------------------
RELEASE 1.09
dbforms.cgi
- Can now update primary keys.
- Removed dependency on ePerl.
- Now takes dsn arguments to cater for variance between DBDs.
INTERFACE CHANGES
Catalog::
- set_primary_key() now sets labels if defined in the catalog.
DataModel::
- New method dsn().
- new() now requires name to be the database name as pattern match
to get database name forgot that this part of a DBI DSN is *non
standard*
- init_db_metadata() now requires DSN for catalog as it varies
between drivers. Also now allows username/password for authentication
against catalog database.
ForeignKey::
- New method sql_where().
Makefile.PL
- Moved most of the catalog initialisation here.
- Manual creation of databases now required as there's no standard
for creating databases. Each driver can use an arbitrarily named
database for testing.
Persistent::
- new() now requires a Catalog object.
- update now takes %attributes argument so that a primary key can be
updated. The current object state is used to update the row WHERE the
primary key matches the values in %attributes.
PrimaryKey::
- html_select_field() now has 'Any' *and* 'NULL' entries. I have a
feeling this still isn't quite right.
- New method as_hidden_html()
- Signature to new() has changed now that label columns are
supported by the catalog.
- html_select_field() now follows label columns which are foreign
keys back to their associated primary key table and uses the label
columns from that table. This gives more meaningful select fields.
Table::
- init_db_metadata() now requires catalog object argument. This
should improve performance as a new catalog object (which involves a
database connect()) won't be created every time this method is called.
- in_foreign_key() now returns a list of foreign keys containing
$attribute
DataType::ANSII::
- Signature to new() has changed. Now requires $ansii_type
argument. All data type objects will need to return their closest
ANSII types as this is the $type which needs to be supplied to
$dbh->quote($value,$type).
- New method ansii_type().
1-04-1999 Paul Sharpe <paul@miraclefish.com>
--------------------------------------------------------------------
RELEASE 1.08
BUG FIX
- Test database wasn't being created which was causing tests to
fail.
28-03-1999 Paul Sharpe <paul@miraclefish.com>
--------------------------------------------------------------------
RELEASE 1.07

RELEASE 1.01 (FIRST PUBLIC RELEASE)
To do
=====
* BUG: dbforms.cgi delete on row consisting of all foreign keys silently fails.
* Improve dbforms.cgi interface. Perhaps a rename is in order too.
I'm thinking of having a single record interface with record
navigation. The form can then be designed and specified as an
argument.
* Fri Jan 8, 1999
BUG - >1 fk relating to the same pk table in a single table is not
handled by dbforms.cgi
4/1/1999
- User-defined templates specify attributes to be used for foreign keys
and ordering
- Allow relationships between the same table (in different roles).
Needs documenting
* Make Bundle::DbFramework
* Schema grammar
- might be better off using Jeeves (from the Panther book)
- should handle relationships of degree >2
- could be CDIF compliant
* Attributes of relationships should be stored so that full schema
including attributes of relationships can be built from meta-data.
* add support for UNIQUE columns (different to ordinary KEYs)
* make primary key in grammar optional (1:1 relationships)
* make relationships optional in grammar
