for-each-repo: do nothing on empty config

2021-01-08T03:12:02Z

'git for-each-repo --config=X' should return success without calling any subcommands when the config key 'X' has no value. The current implementation instead segfaults. A user could run into this issue if they used 'git maintenance start' to initialize their cron schedule using 'git for-each-repo --config=maintenance.repo ...' but then using 'git maintenance unregister' to remove the config option. (Note: 'git maintenance stop' would remove the config _and_ remove the cron schedule.) Add a simple test to ensure this works. Use 'git help --no-such-option' as the potential subcommand to ensure that we will hit a failure if the subcommand is ever run.

branch: sort detached HEAD based on a flag

2021-01-07T23:13:21Z

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 ) 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 Signed-off-by: Junio C Hamano

ref-filter: move ref_sorting flags to a bitfield

2021-01-07T23:13:21Z

Change the reverse/ignore_case/version sort flags in the ref_sorting struct into a bitfield. Having three of them was already a bit unwieldy, but it would be even more so if another flag needed a function like ref_sorting_icase_all() introduced in 76f9e569adb (ref-filter: apply --ignore-case to all sorting keys, 2020-05-03). A follow-up change will introduce such a flag, so let's move this over to a bitfield. Instead of using the usual '#define' pattern I'm using the "enum" pattern from builtin/rebase.c's b4c8eb024af (builtin rebase: support --quiet, 2018-09-04). Perhaps there's a more idiomatic way of doing the "for each in list amend mask" pattern than this "mask/on" variable combo. This function doesn't allow us to e.g. do any arbitrary changes to the bitfield for multiple flags, but I think in this case that's fine. The common case is that we're calling this with a list of one. Signed-off-by: Ævar Arnfjörð Bjarmason Signed-off-by: Junio C Hamano

branch: change "--local" to "--list" in comment

There has never been a "git branch --local", this is just a typo for "--list". Fixes a comment added in 23e714df91c (branch: roll show_detached HEAD into regular ref_list, 2015-09-23). Signed-off-by: Ævar Arnfjörð Bjarmason Signed-off-by: Junio C Hamano
