branch: sort detached HEAD based on a flag Change the ref-filter sorting of detached HEAD to check the FILTER_REFS_DETACHED_HEAD flag, instead of relying on the ref description filled-in by get_head_description() to start with "(", which in turn we expect to ASCII-sort before any other reference. For context, we'd like the detached line to appear first at the start of "git branch -l", e.g.: $ git branch -l * (HEAD detached at <hash>) master This doesn't change that, but improves on a fix made in 28438e84e04 (ref-filter: sort detached HEAD lines firstly, 2019-06-18) and gives the Chinese translation the ability to use its preferred punctuation marks again. In Chinese the fullwidth versions of punctuation like "()" are typically written as (U+FF08 fullwidth left parenthesis), (U+FF09 fullwidth right parenthesis) instead[1]. This form is used in both po/zh_{CN,TW}.po in most cases where "()" is translated in a string. Aside from that improvement to the Chinese translation, it also just makes for cleaner code that we mark any special cases in the ref_array we're sorting with flags and make the sort function aware of them, instead of piggy-backing on the general-case of strcmp() doing the right thing. As seen in the amended tests this made reverse sorting a bit more consistent. Before this we'd sometimes sort this message in the middle, now it's consistently at the beginning or end, depending on whether we're doing a normal or reverse sort. Having it at the end doesn't make much sense either, but at least it behaves consistently now. A follow-up commit will make this behavior under reverse sorting even better. I'm removing the "TRANSLATORS" comments that were in the old code while I'm at it. Those were added in d4919bb288e (ref-filter: move get_head_description() from branch.c, 2017-01-10). I think it's obvious from context, string and translation memory in typical translation tools that these are the same or similar string. 1. https://en.wikipedia.org/wiki/Chinese_punctuation#Marks_similar_to_European_punctuation Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

ref-filter: add --no-contains option to tag/branch/for-each-ref Change the tag, branch & for-each-ref commands to have a --no-contains option in addition to their longstanding --contains options. This allows for finding the last-good rollout tag given a known-bad <commit>. Given a hypothetically bad commit cf5c7253e0, the git version to revert to can be found with this hacky two-liner: (git tag -l 'v[0-9]*'; git tag -l --contains cf5c7253e0 'v[0-9]*') | sort | uniq -c | grep -E '^ *1 ' | awk '{print $2}' | tail -n 10 With this new --no-contains option the same can be achieved with: git tag -l --no-contains cf5c7253e0 'v[0-9]*' | sort | tail -n 10 As the filtering machinery is shared between the tag, branch & for-each-ref commands, implement this for those commands too. A practical use for this with "branch" is e.g. finding branches which were branched off between v2.8.0 and v2.10.0: git branch --contains v2.8.0 --no-contains v2.10.0 The "describe" command also has a --contains option, but its semantics are unrelated to what tag/branch/for-each-ref use --contains for. A --no-contains option for "describe" wouldn't make any sense, other than being exactly equivalent to not supplying --contains at all, which would be confusing at best. Add a --without option to "tag" as an alias for --no-contains, for consistency with --with and --contains. The --with option is undocumented, and possibly the only user of it is Junio (<xmqqefy71iej.fsf@gitster.mtv.corp.google.com>). But it's trivial to support, so let's do that. The additions to the the test suite are inverse copies of the corresponding --contains tests. With this change --no-contains for tag, branch & for-each-ref is just as well tested as the existing --contains option. In addition to those tests, add a test for "tag" which asserts that --no-contains won't find tree/blob tags, which is slightly unintuitive, but consistent with how --contains works & is documented.
