Revision history for Perl extension RPM.
1.51 Tue Apr 24 18:45:49 PDT 2007
Changes made by Alexey to setting of $VERSION in RPM::* classes
didn't play well with CPAN. Since I'm moving the repo to subversion
soon anyway, changed these to ordinary strings.
1.50 Tue Apr 24 17:42:49 PDT 2007
This is an official release to make the work done by Alexey Tourbin
(<at@altlinux.org>) available in the main branch. All of his changes
are merged into the main repository. Without his work, the project
would still be languishing. Beside fixing countless bugs, he got me
back to actively looking at the code.
Added LICENSE paramter in Makefile.PL to re-license the package under
the same terms as Perl itself (dual Artistic/GPL).
RPM.pm version bumped up to 1.50 for release tracking.
Test suites added to t/ for POD correctness and POD coverage.
Several new additions to POD as deficiencies found by the POD
coverage testing.
1.49_01 Sun Apr 22 2007
This release has been tested on ALT Linux Sisyphus (rpm-4.0.4) and
Fedora Core 6 (rpm-4.4.2).
The version has been bumped up to 1.49_01 to match RPM.pm $VERSION.
This release includes about 100 changes from the previous version
0.40, which was released almost 5 years ago. All known bugs and
memory leaks has been fixed; the code has been updated for recent
rpm-4.4 versions [rt.cpan.org #3930, #8710], as well as cleaned up
and simplified.
Detailed list of changes since version 0.40 is available at
http://git.altlinux.org/people/at/packages/?p=perl-RPM.git;a=summary
The most important changes are as follows.
Many memory leaks have been fixed, including lack of headerFree()
in rpmdb_FETCH(). New file t/09_leaks.t implements tests for memory
leaks (requires Devel::Leak module). [rt.cpan.org #12120]
RPM::Database caching layer was dropped, because of unacceptable
memory usage for database traversal. However, due to Berkeley DB
caching facilities, which is used by RPM, the overall performance
seems much smoother.
RPM::Header caching layer was also dropped, due to many
inconsistencies which arise from the "cache by tag name" approach.
(For example, it was possible to assign different values for EPOCH
and SERIAL rpm header tags, which actually alias each other.)
However, ad-hoc cache for NAME, VERSION, and RELEASE tags has been
kept, along with SEGV bugfix. [rt.cpan.org #14489]
XS code has been simplified by implementing RPM::Header and
RPM::Database object boxing (and unboxing) completely with typemap.
Conversion between RPM tag names to their numeric values is now
also handled with typemap.
Fixed wrong rpmError() usage, which expects printf-like format
string and arguments, not just plain string.
Implemented RPM::evrcmp(a,b) to compare [Epoch:]Version[-Release]
specification strings, possibly against RPM::Header objects.
Fixed wrong RPM_INT*_TYPE conversion in rpmhdr_STORE(), which
made RPM::evrcmp() implementation possible.
Update RPM::Constants for new rpm, based on perl-RPM-43.patch
from PLD Linux Distribution.
0.40 Fri May 10 01:09:13 PDT 2002
-alpha thirteen
RPM 3.0 line is no longer going to be supported. It's been long
enough since the 4.0 line came out, I feel. All #ifdef'd code relating
to 3.0 (and 4.0 line before about 4.0.2) has been removed. The code
once again will compile standing on its own within the rpm CVS
repository.
Applied a patch to RPM/Database.xs from Gerald Teschl <gt@esi.ac.at>
so that when a header for a package that exists multiple times in
the db (such as kernel) is requested, the newest of the lot is
returned.
In a related area, the list of potential control-case packages in
t/02_headers.t started with kernel, but if there were two such
packages installed when the tests ran, several of them would fail.
Now, rpm is the first choice.
Applied a modified version of a patch from Anton Berezin
<tobez@FreeBSD.org> to RPM/Header.xs that catches cases where at
the start of key-iteration, the first run of headerNextIterator()
might yield a null (unknown) header key (in rpmhdr_FIRSTKEY).
Applied a patch to RPM/Database.pm to allow options to be passed to
the new() method. Also added documentation for the new() method (!).
Patch was from viktor@vs.nexus.hu.
Applied a patch from Radu Greab <radu@netsoft.ro> that eliminated
a couple of compiler warnings and freed a pointer at destructor-time
that was previously overlooked (RPM/Header.xs and RPM/Error.xs).
Removed all the calls to safemalloc and safefree, replaced them with
the API-correct New (or Newz) and Safefree.
0.32 Tue May 15 00:54:20 PDT 2001
- alpha twelve
Found and fixed a bug in RPM/Database.xs that was causing more of
the "Attempt to free unreferenced scalar" messages. In the process,
noticed that caching of values during iteration wasn't actually
working as designed. The resulting fix should improve database look-ups
fairly noticably.
Two more places found (one in RPM/Header.xs, one in RPM/Database.xs)
that were contributing to memory leakage.
A lot of changes to RPM/Constants.xs in terms of reducing the number
and length of string-compares made in constant look-ups. This is most
noticable in the RPM* set of constants, where the breakdown is the
most granular. On the main dev box (a P-1/233MHz) this sped up the
full test suite by over 25%.
0.31 Fri Apr 27 01:45:37 PDT 2001
- alpha eleven
Re-worked most of RPM/Constants.xs to accomodate the change from
#define to enum values in 4.0.2. This will be released as an
interim version, since Red Hat is shipping 7.1 with this version of
rpm.
0.30 Wed Mar 7 22:13:40 PST 2001
- tenth alpha
Much of the leakage of RPM::Header objects is now gone, due mostly to
changing the prototype of rpmdb_FETCH to returning a SV* instead of
a RPM::Header reference. The various class DESTROY methods seem to be
getting called in the correct order, now.
Caught a case in the RPM::Header class where attempting to reference
an element of a non-existent tag would trigger auto-vivification on
that key, which in turn was leading to some bad calls being made to
the rpmlib routines.
Re-did the av-assignment in rpmhdr_create. This should save on SV*
creation, though it might not have been a leak. Still, this method
is more efficient overall.
Newer versions of rpm 4.0 tickled a bug in which a database offset
value might get sent in without being initialized first. This was
caught and fixed. Also related to the 3.0/4.0 rift, some variables
only used for 3.0.X are now declared within #ifdef's to defeat 'unused'
warnings.
The current state of the module will be released to allow for use by
other parties, without the wait for any ongoing development milestones
on my part.
0.292 Mon Nov 13 22:40:15 PST 2000
- ninth alpha
Some unused variables were found in several places.
Moved away from the self-tie mechanism and instead handle the data
opacity in a completely different fashion. This simplified some code,
muddled some, but ultimately led to the removal of several #define
macros, more unused variable removal, and (hopefully) more stable
code.
Addressed a problem in both RPM::Database and RPM::Header XS code
wherein destructors were not getting called when objects were
implicitly or explicitly freed.
Added more tests to the test suite.
Changed the names of some of the find_* routines in RPM::Database.
See the manual page. The old names were confusing me, despite my
direct familiarity with the code!
The find_* functions in RPM::Database may now take a RPM::Header
object as their argument, and will use the package's name for the
searches.
It's still leaking RPM::Header objects in the RPM::Database routines.
The alternative is a nasty mix of "attempt to free unreferenced
scalar" errors and core dumps.
0.291 Fri Oct 13 01:45:18 PDT 2000
- eighth alpha
The flags that are created from the rpm version are now passed for
3.0.X, as well.
A thread-safing bug was found and fixed in Header.xs. An unused
variable was removed.
Makefile.PL has some large-scale work, including the addition of a
template spec file following the __DATA__ token, code to expand this
file using the values that MakeMaker has derived for the package,
generation of make rules to construct *.rpm and *.srpm files, and
generation of "rpmrc" and "rpmmacro" files to use in invoking rpm
(to force all operation into the local dir area).
0.29 Wed Oct 4 22:29:56 PDT 2000
- seventh alpha
The only change of note in this release is compatibility with version
4.0 of RPM. Additionally, some flags to the C compiler to work with
the gcc that is distributed with Red Hat Linux 7. This version has
been tested on both 6.2 and 7 systems.
0.28 Fri Aug 18 01:29:35 PDT 2000
- sixth alpha
Considerable additions made to the documentation in RPM::Constants, as
well as a few corrections. The prototype of the constant() function
was changed, as well.
Several bugs were addressed in RPM::Header, most notably: Error returns
now correctly return a value of "undef"; A blocking issue surrounding
multiple RPM::Header objects from ftp:// sources is fixed; the mode
with which files are opened was also changed to allow for reading off
of STDIN. The error-return issue was also applied to RPM::Database.
RPM::Header now has a source_name() accessor method that returns the
file name (or URI) that the header was read from. This is null if the
header came from the database.
0.27 Tue Aug 8 00:02:22 PDT 2000
- fifth alpha
Added filenames() method to RPM::Header. This re-assembles the list of
filenames from the components in the tags, BASENAMES, DIRNAMES and
DIRINDEXES.
Added scalar_tag() method to RPM::Header. This returns a 0/1 value
based on whether the return value for a given flag is an array ref or
scalar (respectively). Can be called with either a string or a number
argument. Can be called as a static (class) method.
Added RPM/Error.xs and integrated into the build. All the XS code for
RPM::Error that was previously in RPM.xs has been moved here.
Added export of %RPM to RPM::Database. If requested, this is a hash
pre-tied to the RPM::Database package (and thus the rpm database). One
may also request $RPM and get an object referencing a tied hash.
The return values from fetches on header objects has been completely
revised. Tags are now explicitly defined as scalar or list in nature.
The scalar_tag() method above is a part of this. The return value from
a scalar tag is now a plain scalar. There is no more need for $_->[0]
on scalar returns. Lists are still returned as list references, and
undef is still used to signify problems. Tests have been added to
t/02_headers.t for this, and tests in t/01_database.t were updated to
use the new syntax. This does not obsolete the RPM::Header::NVR method,
as that is a much faster means of fetching those three items than a
stock fetch of the three individual tags would be.
More tags/values documented in RPM::Constants.
0.26 Fri Jul 14 01:03:02 PDT 2000
- fourth alpha
Added NVR() method to RPM::Header for obvious reasons of convenience.
Also added cmpver method, which calls into the rpmCompareVersion() API
hook to compare two headers' version/release data with an internal
algorithm that handles numerical and alpha content in the tags.
Took out all remaining warn()'s and croak()'s, replacing them with
rpm_error() calls. Most notable in the error-return cases of
RPM::Database::init and ::rebuild.
More thread-safing, in particular the heretofore-ignored RPM::Constants
XS module.
Added a sample script in utils, called rpmprune. It has a --help
summary and a man page, see those for details.
0.25 Mon Jun 5 00:54:59 PDT 2000
- third alpha
Fixes to the thread-safing code. When built against a 5.6.0 configured
for threading, several problems were found. All (current) tests now
pass on that configuration.
Added a file, IMPORTANT.perl, to the distribution that explains the
nature of a condition that can prevent the extension from working on
any version of Perl not installed from an rpm.
Still more trimming of tokens out of Constants.pm that are not of use
by the interface being provided. Filled in a few more in terms of
documentation.
Found a case in RPM::Header that would cause core-dumps: Any tags found
by the iterator that were not exported for the API by the rpm lib
could cause a null pointer to be passed through to an entry point that
was several lines past where I had normally checked for the null. This
meant that source RPMs would almost certainly break, since the
offending tags only showed up when I started testing against SRPMS.
Now, the iterators skip over these internal tags. The normal FETCH
method already tested for this, but the interators were sneaking past
those tests.
Added a method to the RPM::Header class, is_source(), that returns a
true value (1) if the header is associated with a source RPM.
0.2 Mon May 29 17:59:20 PDT 2000
- second alpha
Class for RPM::Error added. The code is in the RPM.xs file, but
the docs and accessors are done in RPM/Error.pm.
All sub-classes moved to RPM/.
More documentation added, especially to RPM::Constants.
RPM::Constants had about a dozen or so trimmed out.
Found error in Database.xs where the FIRSTKEY/NEXTKEY pair would
have returned string-ified references instead of package names,
because of not taking the first array element. I really plan to
change the RPM::Header::FETCH interface.
Added two utility functions under the RPM::* space for getting O/S
and architecture names.
Put in the start of thread-safing the module. But this part of the
API is still pretty black in the Lockheed Skunkworks sense of the
word, so it isn't at all complete.
0.1 Mon May 22 00:59:54 PDT 2000
- first alpha release
Classes for RPM::Header and RPM::Database are (more or less) done.
RPM::Constants appears to have everything that is expected to be
needed (i.e., any changes should result in shortening the list of
exported symbols, rather than lengthening it). A basic top-level
RPM namespace is present, but doesn't yet do anything useful. Some
basic test scripts are in place, but more are (always) needed.
