Donenfeld Several options must be specified prior to scan-path. This is consistant source of user confusion. Document these facts.

Donenfeld <Jason@zx2c4.com> 2013-04-10ui-snapshot.c: Prepend "V" when guessing ref namesLukas Fleischer In cgit_print_snapshot_links() we strip leading "v" and "V", while we currently only prepend a lower case "v" when parsing a snapshot file name. This results in broken snapshot links for tags that start with an upper case "V". Avoid this by prepending a "V" as a fallback. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de> 2013-04-10t0107: Skip ZIP tests if unzip(1) isn't availableLukas Fleischer Note that we cannot use skip_all here since some tests have already been executed when ZIP tests are reached. Use test prerequisites to skip everything using unzip(1) if the binary is not available instead. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de> 2013-04-10tests/: Do not use `sed -i`Lukas Fleischer "-i" isn't part of the POSIX standard and doesn't work on several platforms such as OpenBSD. Use a temporary file instead. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de> 2013-04-10Add branch-sort and repo.branch-sort options.Jason A. Donenfeld When set to "name", branches are sorted by name, which is the current default. When set to "age", branches are sorted by the age of the repository. This feature was requested by Konstantin Ryabitsev for use on kernel.org. Proposed-by: Konstantin Ryabitsev <mricon@kernel.org> 2013-04-10t0109: chain operations with &&John Keeping Without '&&' between operations, we will not detect if strace or cgit exit with an error status, which would cause a false positive test status in this case.

However, some setenv() implementations crash if a NULL pointer is passed as second argument. Only restore variables that are not NULL. See commit d96d2c98ebc4c2d3765f5b35c4142e0e828a421b for a related patch. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de> 2013-04-09t0107: Use `tar -z` for gzip'ed archivesLukas Fleischer
