This patch is broken: 1. $OPTIONS is used (unquoted) in 4 different places but this patch only updates one of them 2. Quoting $OPTIONS prevents use of multiple options
Unfortunately I don't see a reasonable way to fix this while using only POSIX shell features. - If bzdiff is changed to use bash then the options can be accumulated into an array variable. This would be fine in Debian and Ubuntu, but not upstream. - POSIX allows positional arguments to be used in an array-like way, but we already use them for the filenames. - This could be done by escaping, quoting and concatenating the options and then using eval to expand to multiple arguments. But this is not what I would consider reasonable! -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to bzip2 in Ubuntu. https://bugs.launchpad.net/bugs/735675 Title: bzdiff does not pass -I option to diff Status in bzip2 package in Ubuntu: New Bug description: Binary package hint: bzip2 When trying to use bzdiff with the -I option (ignore regex), the options are not properly passed to diff. I have 2 files (MySQL dumps) that differ in only one line: $ bzdiff tmp1.bz2 tmp2.bz2 9c9 < -- Dump completed on 2011-03-11 1:06:50 --- > -- Dump completed on 2011-03-11 0:40:11 However, when trying to avoid that line from matching a problem arises: $ ./bzdiff_orig -I'Dump completed' tmp1.bz2 tmp2.bz2 diff: extra operand `/tmp/bzdiff.JnwGRlHnMM' diff: Try `diff --help' for more information. After some attempts at quoting and unquoting, I solved the problem by modifying the bzdiff shell script at /bin/bzdiff. The issues were 2: i) the options were not correctly parsed, a space was added before the first option, and ii) the options were not passed quoted to diff, therefore they were incorrectly interpreted as a file and not an option. Will include a patch.
