Project page for libpng version 1.4
Goal
Develop a stable and robust libpng 1.2 to 1.4 upgrade path and make sure all spells work with libpng 1.4
Tasks
- Upgrades from prior libpng version successfully without breakage
- All spells depending on libpng must cast successfully and work with version 1.4
- Passes all test cases detailed here
Information
The work is being done in the git branch devel-libpng. It will be merged with the normal test grimoire when the goal is accomplished.
How to help out
scribe add libpng from git://download.sourcemage.org/smgl/grimoire.git:libpng:devel-libpng

Open Issues
Cairo
cairo 1.8.8 doesn't compile with libpng 1.4, cairo 1.8.10 does, but there are stability problems between cairo 1.8.10 and firefox and friends (or probably xulrunner). For now the devel-libpng branch has cairo 1.8.10 but we need to sort this out before the branch can be merged back into master.
Stealth's findings:
1.8.10 has been known buggy for the last few months as a reason for random crashing of gtk (and not only) apps mostly with such message: -- The program 'firefox' received an X Window System error. This probably reflects a bug in the program. The error was 'RenderBadPicture (invalid Picture parameter)'. (Details: serial 955915 error_code 169 request_code 152 minor_code 7) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) Segmentation fault -- This affects at least seamonkey, firefox, sylpheed, gajim, xchat and any other program which is lanched for >20 hours. Some kind of memleak is detected. To solve this problem, distributions build firefox, seamonkey, etc. with a holy, stable, and internal cairo library, but that doesn't solve the issue for small apps like sylpheed and xchat (since cairo isn't shipped with them).
Added patch to version 1.8.8 (with commit 3ea3d0f246dcc3bad74c1f0e8ab11b6fa4be1b47) so it compiles for me. Please report it also worked for you. - PyroBor
