Muldis::DB
---------------------------------------------------------------------------
2007-07-24 Darren Duncan <perl@DarrenDuncan.net>
* Muldis::DB version 0.3.0 for Perl 5 is released on CPAN as
Muldis-DB-0.3.0.tar.gz. Muldis::DB version 0.3.0 for Perl 6 is not
released at this time, if ever, since it is currently released only as
part of the Perl6-Pugs project (in its ext/Muldis-DB/ subdirectory),
which sets its own less frequent release schedule. The rest of this
Changes entry refers only to the Perl 5 version.
* What was Muldis-DB at version 0.2.0 and earlier, has been split in 2,
with the parts to be Language-MuldisD and Muldis-DB, each at version
0.3.0 and later. Prior to the split, both the Perl 5 and Perl 6
versions of Muldis-DB contained identical copies of what became
Language-MuldisD; after the split, neither Muldis-D had a copy.
* All versioned files had their version numbers brought up to 0.3.0.
* This release saw no code changes at all. About half of SeeAlso.pod
was stripped out, since that stayed only with Language-MuldisD.
* This is the Muldis-DB-0.3.0 file manifest:

* Muldis::DB version 0.2.0 for Perl 5 is released on CPAN as
Muldis-DB-0.2.0.tar.gz. Muldis::DB version 0.2.0 for Perl 6 is not
released at all. The rest of this Changes entry refers only to the
Perl 5 version, specifically the portions that were not split-off into
Language-MuldisD following release 0.2.0.
* Renamed AST.pm to Literal.pm, and split up DB.pm into DB.pod and
Interface.pm. Any code that used to be spelled Muldis::DB::AST or
Muldis::DB is now spelled Muldis::DB::Literal and
Muldis::DB::Interface. Following these changes, lib/Muldis/DB.pod is
still the "main" file for documentation purposes, but for code
purposes, both Literal.pm and Interface.pm are now used directly.
* New file versions are: DB.pod and Literal.pm and Interface.pm and
Language.pod and Validator.pm and Example.pm 0.2.0.
* Updated Literal.pm to remove all exported functions that trivially
wrap an object constructor, updated any uses in other files to call
constructors directly. Also renamed ::(Bool|Order|Int|Blob|Text)Lit to
remove the "Lit", and ::(|Quasi)(Tuple|Relation)Sel to remove the
"Sel", and likewise updated any refs to said.
* In both Literal.pm and PhysType.pm, renamed any classes named
(TypeInvo|TypeDict|ExprDict|ValueDict)(|NQ|AQ) to (_\1|\1|Quasi\1)
respectively, and refs to said.

* Muldis::DB version 0.1.0 for Perl 5 is released on CPAN as
Muldis-DB-0.1.0.tar.gz. Muldis::DB version 0.1.0 for Perl 6 is not
released at all. The rest of this Changes entry refers only to the
Perl 5 version, specifically the portions that were not split-off into
Language-MuldisD following release 0.2.0.
* This is a major release that focuses on overhauling or defining part
of the Muldis D meta-model / system catalog, which is essential for
supporting any user-defined DBMS entities, that is, for doing anything
remotely useful. Said overhaul is expected to be staged over 3-4
consecutive releases, of which the current one is essentially just
updating documentation; not much code was changed by this release.
* New code file versions are: DB.pm and AST.pm and Validator.pm and
Example.pm 0.1.0.
* As of this release, all pod-only files now also have version numbers,
shown in the VERSION docs by NAME, like code-containing modules do; the
initial version numbers are all 0.1.0.
* Muldis D now has 2 representation formats (Concrete Muldis D,
Abstract Muldis D) rather than 3 (relations, ASTs, strings).
* Updated SeeAlso.pod to remove the proposal for a separately
distributed Muldis::DB::AST::StringRepr module; instead,
Muldis::DB::AST will parse and generate Concrete Muldis D by itself.
* Rearranged any relevant docs and code so that the most important core
scalar types are now in the order [Bool, Int, Blob, Text] and the
relation type factory Maybe now appears after Set.
* Muldis D now has a new scalar data type, "Order", which is an
enumeration (like "Bool" is) of 3 values: [Increase, Same, Decrease];
it is the result type of any binary comparison operator that underlies
the likes of less|greater-than or min|max or sorting operations. Both
AST.pm and PhysType.pm were updated to include this type.

* Muldis::DB version 0.0.1 for Perl 5 is released on CPAN as
Muldis-DB-0.0.1.tar.gz. Muldis::DB version 0.0.1 for Perl 6 is not
released at all. The rest of this Changes entry refers only to the
Perl 5 version, specifically the portions that were not split-off into
Language-MuldisD following release 0.2.0.
* New code file versions are: DB.pm and AST.pm and Validator.pm and
Example.pm 0.0.1.
* The primary purpose of this release is to re-license Muldis::DB under
actual free software licenses, specifically version 3 of the GPL family
of licenses, which the Free Software Foundation formally published on
2007 June 29th. By contrast, the previous Muldis::DB releases were
under an expiring proprietary license, with just the promise of a free
re-license to come. Accordingly, the file LICENSE/GPL was added to
this distro, which contains the text of the GPL version 3.0.
* This release also includes a collection of small documentation
updates and fixes, such as the following: We now use the official
typography for the names 'TTM' and 'D' and such. Added a DOCUMENTATION
READING ORDER section to the README file. Added the 2007 June 4th
Muldis::DB namespace registration (to the official CPAN module list)
notice to the Changes file. Updated parts of DB.pm and Copying.pod
concerning licensing matters. This release has no code changes.

* Muldis::DB version 0.0.0 for Perl 5 is released on CPAN as
Muldis-DB-0.0.0.tar.gz. Muldis::DB version 0.0.0 for Perl 6 is not
released at all. The rest of this Changes entry refers only to the
Perl 5 version, specifically the portions that were not split-off into
Language-MuldisD following release 0.2.0.
* This is the first release of the Perl 5 Muldis-DB distribution, and
the first release of any distribution to contain Perl 5 modules named
Muldis::DB::\w+.
* This is the initial file manifest:

* Initial code file versions are: DB.pm and AST.pm and Validator.pm and
Example.pm and PhysType.pm and Operators.pm 0.0.0.
* As of this release, Muldis-DB is officially in pre-alpha development
status. A lot of documentation and functionality is present, but a lot
isn't. What is mostly done is the higher level documentation plus an
alpha-quality but fundamentally stable public API implementation. What
is mostly undone is the reference engine implementation, the test
suite, and documentation of the API details. What is already present
should be sufficient to begin study of Muldis-DB such that it can
actually be put to use within the next few weeks or months as Muldis-DB
is fleshed out. Also, it should be possible now to start writing code
that uses or extends it.
