This week-end, I wanted to edit a chestnut image, to put some brightness on this blog (and I love doing chestnut things). So, I fired up cooker's gimp. But I didn't really expect this marathon...
First, gimp 2.317 is not really usable, as explained on the release notes, mainly because of a segfault on selection copy. So, I backported revision 22643 patch from Gimp, and rebuilt the package. It still again. After the backport of several more patches that make proper use of g_slice, gimp still failed to run properly.
But this time, it was because of a mysterious Xlib error. On IRC, Liam pointed me to an upstream report that incrimates Xlib. The crash appearing in the latest 1.1.2 libX11 release.
So, I had to run a bisection on about 24 commits. I did that by rebuilding a snaphost of each revision and the rpm package (adding automake -a and autoheader calls to build from raw tarball).

Unfortunately, this "codestyle" patch was about 3000 lines long, let's go for another bisection round...
$ git log -p a48386ce6b5f8fd2d9dc11a966c9bf5da59f3831 > /home/blino/vc/mandriva/packages/cooker/libx11/SOURCES/libX11-1.1.2-codestyle.patch # revert patch on libX11 1.1.1 (cd BUILD/libX11-1.1.2/; patch -p1 < ../../SOURCES/libX11-1.1.2-codestyle.patch) # edit patch and remove some hunks, using manual bisection /o\ (cd BUILD/libX11-1.1.2/; patch -R -p1 < ../../SOURCES/libX11-1.1.2-codestyle.patch && make -j4) && bm -l -i --short-circuit && bm -l -b --short-circuit # try testcase
Finally, gimp works \o/ but my initial photograph is barely usable, the poor chestnuts being incomplete or too dark :-/ (and I was too tired to proceed with crafty tactics...)
I also submitted a 2.3.17 gimp package with my backports in cooker, but the build system was borked (for a change). And gimp 2.3.18 has been released in the meantime, gee!
