Bugzilla Bug 153292

The app-arch/rpm-4.4.6-r2 does not appear to package the magic* files in
/usr/lib/rpm, required by rpmbuild when building packages.

The missing files are:
/usr/lib/rpm/magic
/usr/lib/rpm/magic.mgc
/usr/lib/rpm/magic.mime
/usr/lib/rpm/magic.mime.mgc

Apparently, due to a libmagic (sys-apps/file) bug, some attributes of an
internal structure, struct magic_set, are left uninitialized, producing a
segfault. [There is a workaround for the file/libmagic segfault at
https://lists.ubuntu.com/archives/ubuntu-devel/2006-April/017052.html, but it's
not a legitimate fix for the bug - it only avoids the segfault and prints a
nonsensical error]

CCing the herd of sys-apps/file. If it's a sys-apps/file bug they should be
aware of it :-)

(In reply to comment #1)
Actually, the sys-apps/file bug should be separate one. But as there is no real
fix currently available anywhere, I did not bother to report it separately.

The libmagic bug is only visible due to a bug in the app-arch/rpm ebuild.

we'll handle the rpm issue here

we purposefully punt the file stuff from rpm ... it should be provided by the
file package, not by rpm

*** Bug 156655 has been marked as a duplicate of this bug. ***

Please unmask =app-arch/rpm-4.4.7-r2 and test it on your system.

app-arch/rpm-4.4.7-r2's rpmbuild segfaults from a double free in the code,
before it even does anything.  I can give you more details, but I have -O3 in
my CFLAGS on an i686.  This is still a bug in 4.4.6-r?.

app-arch/rpm-4.4.7-r2 USE="berkdb java nls perl python -doc -lua -minimal
-sqlite -threads"
app-arch/rpm-4.4.6-r3 USE="nls perl python -doc -sqlite -berkdb -java -lua
-minimal -threads"

unrelated to this issue; file a new bug

Could we please fix app-arch/rpm-4.4.6-r3 so that it generates the magic.mgc
file, even manually?  I don't care if it's added to the ebuild or patched
against the Makefile.in, but *something* needs to be done for version 4.4.6,
since 4.4.7 is unstable.

I can generate either a patch against the Makefile.in/Makefile.am or create a
new ebuild if you want, whichever seems a better solution to you, but something
needs to be done for 4.4.6.

I'm testing a new ebuild which symlink magic* files from installed file package
into rpm var/lib dir and solve other issues. I hope that will fix this bug.

Feel free to submit a patch,an ebuild, whatever, rpm is quite difficult to
maintain and I don't refuse any qualifyed help. I'm in contact with upstream
and I'm trying to have rpm working. If you can fix bugs, you're welcome.

Please test new ebuilds:
rpm-4.4.6-r4, rpm-4.4.7-r2 and if non of them works, unmask rpm-4.4.7-r3 and
test  that also.
Thanks for your patience, I've been very busy this month.

*** Bug 167943 has been marked as a duplicate of this bug. ***

I tried those:

* app-arch/rpm-4.4.7-r2 is still missing the magic.* files, and segfaults
before it even gets that far.

* app-arch/rpm-4.4.6-r4 works so far!

rpm-5.0_alpha4 now in the tree

I compiled with:
 FEATURES=keepwork emerge -av rpm

After the emerge, I copied the pm.magic file to /usr/lib/rpm/magic

cp /var/tmp/portage/app-arch/rpm-4.4.6-r3/work/rpm-4.4.6/rpm.magic 
/usr/lib/rpm/magic

Now, I can compile my packages
