Description Tomas Hoger 2014-03-25 13:20:50 UTC
+++ This bug was initially created as a clone of Bug #1080450 +++

Description of problem:
The way patches are applied to files in magic/Magdir is rather fragile.  While %patch is run without -b (as also noted in .spec: Don't use -b -- it will lead to poblems when compiling magic file!), for any patch that fails to apply cleanly, .orig backup file is still created.  This leads to having both patched and unpatched rules in resulting /usr/share/magic file.

Currently, file-5.04-generic-msdos.patch is misapplied:

http://kojipkgs.fedoraproject.org/packages/file/5.14/20.fc20/data/logs/x86_64/build.log

+ echo 'Patch #6 (file-5.04-generic-msdos.patch):'
Patch #6 (file-5.04-generic-msdos.patch):
+ /usr/bin/cat /builddir/build/SOURCES/file-5.04-generic-msdos.patch
+ /usr/bin/patch -p1 --fuzz=0
patching file magic/Magdir/msdos
Hunk #1 succeeded at 320 (offset 1 line).
Hunk #2 succeeded at 397 (offset 1 line).
Hunk #3 succeeded at 438 (offset 1 line).

Resulting /usr/share/magic contains both patched and unpatched rules.

Version-Release number of selected component (if applicable):
file-5.14-20.fc20

Comment 1 Tomas Hoger 2014-03-25 13:21:57 UTC
There are few more in RHEL-6:

magic/Magdir/linux.orig
magic/Magdir/misctools.orig
magic/Magdir/msdos.orig
magic/Magdir/python.orig
magic/Magdir/rpm.orig

Most of them seem to add new rules rather than remove existing, as is the case for file-5.04-generic-msdos.patch.
