Though the intersection check can be useful even for /usr/src/debug
(it indicates binary code duplication and/or poor dependencies between
subpackages), it is too noisy and can eat up quite a bit of output.
The same information is still available directly within the packages
or via contents_index.
Note that checkHardLinks function is now removed. It was unclear
whether it was supposed to verify %lang attributes (returning non-zero
on error) or indicate if all hardlinks are packaged within the package.
It turns out that only a single package in our repo has
PartialHardlinkSets dependency:
$ cd /ALT/Sisyphus/files/x86_64/RPMS/
$ rpm -qp --qf '[%{NAME}\t%{REQUIRENAME}\n]' *.rpm |fgrep 'PartialHardlinkSets'
$ cd /ALT/Sisyphus/files/noarch/RPMS/
$ rpm -qp --qf '[%{NAME}\t%{REQUIRENAME}\n]' *.rpm |fgrep 'PartialHardlinkSets'
freeciv-common rpmlib(PartialHardlinkSets)
$
This probably means that freeciv-common has hardlinks with different
%lang attributes (which probably was supposed to be an error). So
the whole issue should be reconsidered. A leave XXX marks in the
code and suggest new PartialHardlinkSets implementation (however,
the dependency is not being added yet).
Note that 'sh -e' mode is unreliable when the last pipeline command
is non-simple command (such as while loop). So the script was somehow
failing on hardlinks and it went unnoticed. I choose to replace
pipe-to-while with a temporary file for now.
When pkg1 has strict dependency on pkg2, all other non-strict/virtual
dependencies on pkg2 will be reaped off pkg1. Note that the are subtle
cases: though I try to make something about merging dependency flags,
it is not always possible, as the dependency on pkg2 can be obtained
via a transitive chain. I see this being a non-critical issue which
is worthwhile to be mentioned.
Basically, if pkg1 has strict dependency on pkg2, the question
is whether pkg1-debuginfo should possess a strict dependency on
pkg2-debuginfo. The answer is "yes" provided that pkg1-debuginfo
is already dependent on pkg2-debuginfo (i.e. has new soname-based
debuginfo dependencies resolved to pkg2-debuginfo). This provides
an opportunity for dependency optimization between dependend
debuginfo subpackages.
This finally provides missing strip controls. Note that even with
STRIP_NONE, the file will be edited with debugedit. So there is no
way to bypass brp-debuginfo completely (and maybe we should tolerate
debugedit failures with STRIP_NONE). But there is also an advantage:
/usr/src/debug sources will be installed even for non-stripped files!
This is why sources are now associated with .debuginfo/src/"$f"
instead of .debuginfo/src/"$debugf".
It might seem that build-id links should be created in brp-debuginfo.
However, there are corner cases: in brp-debugino, it is not yet known
which files are going to be packaged. This might be a problem when a
few identical files or hardlinks are created under buildroot: it is
possible create a symbolic link to a "wrong" file which will not be
packaged.
The solution is create build-id links in find-debuginfo-files: the link
will point to the first packaged file with the given build-id. However,
note that find-debuginfo-files is not part of the install stage, and
should remain "reenterable" (so that e.g. rpm -bl can be executed
multiple times). This means that the script should not make assumptions
whether the links have already been created.
The output now is like this:
removing 12 sources from rpm-debuginfo and adding dependency on librpm-debuginfo
removing 11 sources from rpm-debuginfo and adding dependency on librpmbuild-debuginfo
removing 13 sources from rpm-build-debuginfo and adding dependency on rpm-debuginfo
removing 14 sources from rpm-static-debuginfo and adding dependency on rpm-debuginfo
removing 20 sources from librpmbuild-debuginfo and adding dependency on librpm-debuginfo
removing 13 sources from rpm-build-debuginfo and adding dependency on librpm-debuginfo
removing 80 sources from rpm-static-debuginfo and adding dependency on librpm-debuginfo
removing 12 sources from python-module-rpm-debuginfo and adding dependency on librpm-debuginfo
removing 12 sources from rpm-build-debuginfo and adding dependency on librpmbuild-debuginfo
removing 35 sources from rpm-static-debuginfo and adding dependency on librpmbuild-debuginfo
The output is like this:
remove sources from rpm-debuginfo because it requires librpm-debuginfo
remove sources from rpm-debuginfo because it requires librpmbuild-debuginfo
remove sources from rpm-build-debuginfo because it requires rpm-debuginfo
remove sources from rpm-static-debuginfo because it requires rpm-debuginfo
remove sources from librpmbuild-debuginfo because it requires librpm-debuginfo
remove sources from rpm-build-debuginfo because it requires librpm-debuginfo
remove sources from rpm-static-debuginfo because it requires librpm-debuginfo
remove sources from python-module-rpm-debuginfo because it requires librpm-debuginfo
remove sources from rpm-build-debuginfo because it requires librpmbuild-debuginfo
remove sources from rpm-static-debuginfo because it requires librpmbuild-debuginfo
- debugedit.c: Imported from rpm.org.
- brp-debuginfo: Initial revision, replaces brp-strip.
- verify-elf: Do not descend into /usr/lib/debug.
- build/checkFiles.c: Skip /usr/lib/debug and /usr/src/debug for now.
- platform.in: Always use -g in %optflags.

71a7dd8 2009-06-16 Panu Matilainen Add debugedit support for DWARF-3 (RhBug:505774)
- Removed --fileid query selector and Filemd5s rpmdb index (rpm.org).
- Removed ancient dependency loop whiteout mechanism (rpm.org).
- rpmdb.c: Do not exclude Requires(pre) dependencies from rpmdb index.
- Implemented %__find_{requires,provides}_filter macros (lower-level) and
%filter_from_{requires,provides} (higher-level, compatible with Fedora).
The first two macros provide general mechanism for find-requires
and find-provides filtering. Any valid command or shell syntax can
be used - the command will be executed using "eval" within find-*
script. The implementation in %___build_pre is not particular
beautiful (as it uses here-docs), but there seems to be no easy
way to quote for eval yet.
The second two commands are built on top of the first: they use
sed as a filtering tool. The implementation is compatible with Fedora:

It can be observed that, while packages require their dependencies,
the dependencies in turn are not always required by their packages:

This is because rpm removes "install prerequisites" from rpmdb index.
As a consequence, rpm will allow (but apt will not) to remove packages
with "not required" dependencies:
$ rpm -e --test x11presetdrv
$
This is possibly wrong, and it makes dependency optimization hard (e.g.
can't merge duplicate names with different flags). Also, the code was
buggy: testing isInstallPreReq was not enough as it is not mutually
exclusive with isErasePreReq - e.g. Requries(pre,preun) dependencies
can be used in specfile.
