I'm trying to patch Bash 4.2 with the latest patch 049. It appears as if the patch file itself is corrupted. The corresponding patch 026 for Bash 4.3 is fine.
When running patch with mostly default arguments, it seems to work but has to use merge fuzzing, which it complains about... $ patch -p0 <../bash4.2-patches/bash42-049 patching file parse.y Hunk #2 succeeded at 6062 with fuzz 2 (offset -2317 lines). patching file patchlevel.h However when patching with fuzzing disabled (--fuzz=0) the patch will completely fail. It should be noted that Fedora Linux and perhaps other RPM-based distros always apply patches (when using the rpmbuild tool) with fuzzing set to zero intentionally to catch broken patch files. The output then is: $ patch -p0 --fuzz=0 <../bash4.2-patches/bash42-049 patching file parse.y Hunk #2 FAILED at 8379. 1 out of 2 hunks FAILED -- saving rejects to file parse.y.rej patching file patchlevel.h Here's the patch file checksum that I got from the FTP server. I also validated the GPG signature of the patch file, which was good. $ sha1sum bash42-049 fce8e1026c0480321b3ee5a9ccef955955a4d5f3 bash42-049 After some investigation and comparing it with 4.3 patch 26, it looks like the 49 patch file is missing a file name separator. The patch chunk that is attempting to remove a blank line at the end of the file after the line, #endif /* HANDLE_MULTIBYTE */ should be trying to remove it from the file "y.tab.c", but is instead trying to modify the file "parse.y". I suspect there may be another patch chunk that is also missing from the middle of the patch file too. On an unrelated note, I have also tried to compare sources against the Savannah Git repository, and I noted that the repository has a couple small differences from the FTP files + patches. The Git repo has a blank file called "-i", probably an accident of some command line arguments. The repo also has a few extra files not in the FTP version — though those differences may be intentional (?) Comparing Bash 4.3 patchlevel 26 from the FTP version and Git commit 836a17be08ee0696b89367ab1aa27d0be87169ed: $ diff -q -r -x .git bash-4.3.26 bash-git Only in bash-git: configure.in Only in bash-git/CWRU: audit-patch Only in bash-git/CWRU: mh-folder-comp Only in bash-git: -i Only in bash-git: MANIFEST.doc Only in bash-git/tests: cond-regexp.sub Thanks for your efforts these past few days.
