Muldis::D
Changes
---------------------------------------------------------------------------
2015-03-07
* Muldis::D version 0.200.1 is released on CPAN as
Muldis-D-0.200.1.tar.gz.
* The main purpose of this release is to simplify the distribution by
removing all Perl code save for the (also simplified) Makefile.PL.
Muldis::D was only ever intended to be a pure documentation
distribution but until now it was also saddled with some legacy cruft
in the form of a dummy/empty Muldis::D Perl package plus a trivial
t/*.t in order for the CPAN tool chain or CPAN Testers to not falsely
claim test failures or other problems with the distribution. But the
proper solution is to get rid of this pointless code and unnecessary
automated testing, which also leads to confusion by readers as to why
it is there, and then if the modern CPAN has problems with the lack of
code, we then deal with that in some more appropriate way.
* Renamed lib/Muldis/D.pm to lib/Muldis/D.pod and stripped the dummy
Muldis::D Perl package from it; the POD content is unchanged. As a
consequential benefit, GitHub now automatically renders the POD for
that file like with the other POD files. Deleted
t/Muldis_D_00_Compile.t and updated INSTALL to remove any mention of a
'make test' step for installing this distribution. Simplified the
Makefile.PL to no longer require any minimal version of Perl.
* Updated all files using the incorrect terminology "curried", in
reference to partial function application, to say "primed" instead;
some types or routines/parameters were renamed as part of this.
* Purged this distribution's "Changes" file of practically all change
details for its approximately 23 releases numbered 0.129.1 thru 0.200,
most of those now just constituting a single bullet-point in total. If
you want to see those change descriptions, look either in the version
control system as of tag "release-0.200" or in the archived
distribution tarball named Muldis-D-0.200.tar.gz.
* This is the Muldis-D-0.200.1 file manifest:

* Muldis::D version 0.129.1 is released on CPAN as
Muldis-D-0.129.1.tar.gz. This release marked a milestone for Muldis D
in that, for the first time, the language specification had been
considered by its author to be fundamentally complete, with all of the
important details formally specified. Prior to that milestone, some
important details were missing, and so it would have been difficult to
demonstrate what actual Muldis D code looked like, whereas then it was
considered by its author as feasible to write and understand code for
any given task. In retrospect, the language still needed a lot of
substantial design changes in order to be good enough to fully
implement, but at that time it was done enough that its author widely
announced the 0.129.1 "fundamentally complete" release.
* Purged this distribution's "Changes" file of practically all change
details for its approximately 147 releases numbered 0.0.0 thru 0.129.0,
most of those now just constituting a single bullet-point in total. If
you want to see those change descriptions, look either in the version
control system as of tag "release-0.129.0" or in the archived
distribution tarball named Muldis-D-0.129.0.tar.gz.

name Muldis::DB::Language.
* 2007-06-29 : Muldis::DB::Language version 0.0.1.
* 2007-07-11 : Muldis::DB::Language version 0.1.0.
* On 2007-07-20 was the very last CPAN release, as
Muldis-DB-0.2.0.tar.gz, of "Muldis DB for Perl 5" that bundled the
Muldis D language spec, version 0.2.0. After this time the two would
be released separately, in their own namespaces.
2006-09-15 thru 2007-06-02
* Started rewriting Rosetta again, but with a name change, since
"Rosetta" was no longer appropriate for various reasons. This rewrite
took the intentionally bad and temporary name QDRDBMS, to be renamed
again (to Muldis DB) later on. With the name change allowed for the
previous version numbering of Rosetta to be dropped, and this rewrite
would eventually be first released as version zero.
* QDRDBMS was started in the wake of having had a lot more experience
in reading up on the truly relational model of data, and was now
designed fundamentally to be the design and implementation of a new
turing complete programming language for working with relational
databases, now called "QDRDBMS D".
* Made an experimental CPAN release of QDRDBMS version 0.0.0 on
2007-05-31, which specifically was a quick branch that stripped out all
the code and just contained the documentation. This was the only CPAN
release of the (partial) project under the QDRDBMS name.
* Shortly after this, QDRDBMS was renamed to its presumably final name
of "Muldis DB", and its command language to "Muldis D". But while
"Muldis D" stuck, "Muldis DB" was fated for a further rename later.
2006-04-14 thru 2006-11-22
* Started a complementary Perl 6 project named "Relation" which was
intended to provide native tuple and relation data types for ordinary
use in Perl 6 programs like other built-in collection types. It is
now stagnant; it will likely get un-stuck after Muldis Rosetta sets an
example for it.
2006-02-01 thru 2006-04-13
* The first simultaneous releases of the Perl 5 and 6 versions of
Rosetta's rewrite occurred on 2006-02-01; they were also the first CPAN
releases of either version. The Perl 6 one was Pugs release 6.2.11
(SVN rev 8934).
* On 2006-02-23 was the first (Perl 5) CPAN release of Rosetta where
the project was then officially an implementation of "The Third
Manifesto", the central work of Darwen and Date's DBMS proposal;
moreover, Rosetta's command language was named "Rosetta D", to be a "D"
language by the terms of said proposal.
* On 2006-03-20 was the (Perl 5) release that declared Rosetta was to
be fundamentally a self-contained relational DBMS (and the core
distribution would bundle such an implementation of its API) rather
than "just" a DBMS wrapper; though extensions could still chose to
operate as wrappers over other DBMSs.
* On 2006-04-13 was the last CPAN release of the Perl 5 Rosetta, and
Pugs 6.2.12 (SVN rev 10930), on 2006-06-26, had the corresponding Perl
6 version; Pugs 6.2.13 (SVN rev 11402), on 2006-10-27, had the last
CPAN release of Perl 6 Rosetta, with trivial Perl 6 only updates.
After this, Pugs would have a Muldis Rosetta instead.
2005-12-06 thru 2006-01-31
* Rosetta started to evolve so that its API and design was based on
relational algebra, which is a lot of smaller generic constructs that
can easily be arranged into queries; this is in contrast to the
previous design based around monolithic and unwieldy SQL "select"
queries. Generally speaking, there was increasing influence on the
design by Hugh Darwen's and Chris Date's proposals on how a truly
relational DBMS should work. This time period also saw very little
code, and almost entirely documentation updates.
2005-12-05
* Darren Duncan is introduced by David Wheeler to the truly relational
model of data, in a posting on the Bricolage development list in the
"Re: [6977] New branch for maintenance of Bricolage 1.10.x." thread.
* David said that Darren's expressed thought, that compound data types
in table fields was a violation of first normal form, was in fact a
misconception about the relational model. David then referenced a
recent interview with C.J. Date.
* This set off a chain of events which was the largest paradigm shift
to ever affect the Rosetta project. While the continuing goal of
Rosetta remained largely the same, the way this was to be accomplished
would become quite different, and the project would gain a new goal, to
help improve the design of relational DBMSs themselves.
2005-09-30 thru 2005-12-04
* Started a full rewrite of Rosetta, with the intent of avoiding being
over-engineered, and cutting corners in the short term so to get
something useable at all sooner. The idea was to focus on vertical
development first, so that at least a subset of features work earlier,
taking the development strategy of Perl6-Pugs itself as an example;
this is in contrast to the more horizontal development strategy of the
first Rosetta implementation.
* Moreover, this rewrite was being done simultaneously in both Perl 5
and Perl 6; each language had its own independent but synchronized
version, with the Perl 6 one intended to be the main future one that
guided design decisions, and the Perl 5 one intended to be the one
production-ready first, to be used until Perl 6 itself was production
ready. That co-development was maintained afterwards, and happens with
the Muldis Rosetta core.
2002-11-12 thru 2005-09-28, plus 2006-01-13
* Developed and released on CPAN the Rosetta DBMS framework, whose
intended purpose was to provide rigorous portability of database
schemas and database-using applications between different SQL DBMS
products. A lot of design documentation was produced, as well as some
code and tests, but while a significant amount of executing code was
produced, no solution emerged that was actually useable for real work;
what did get produced was also unnecessarily complicated.
* The very first CPAN release of anything related to Rosetta was on
2003-01-05, in the form of DBIx::Portable version 0.01, as
DBIx-Portable-0.01.tar.gz.
* A Lightning Talk was also given introducing Rosetta at OSCON 2005;
but it is Muldis Rosetta instead that will fulfill the promises made in
it.
2002-06-07
* Started writing self-contained code components that were explicitly
designed to enable external code that used them to work seamlessly on
multiple database products. Some of this work was reused later in the
Rosetta DBMS framework et al, and hence 2002 is the start of the
declared copyright date range for Muldis D language specification.
