2021-03-19Merge branch 'rs/xcalloc-takes-nelem-first'Libravatar Junio C Hamano1-0/+10
Code cleanup. * rs/xcalloc-takes-nelem-first: fix xcalloc() argument order
2021-03-15cocci: allow xcalloc(1, size)Libravatar Junio C Hamano1-1/+1
Allocating a pre-cleared single element is quite common and it is misleading to use CALLOC_ARRAY(); these allocations that would be affected without this change are not allocating an array. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2021-03-13use CALLOC_ARRAYLibravatar René Scharfe1-0/+8
Add and apply a semantic patch for converting code that open-codes CALLOC_ARRAY to use it instead. It shortens the code and infers the element size automatically. Signed-off-by: René Scharfe <l.s.r@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2021-03-08fix xcalloc() argument orderLibravatar René Scharfe1-0/+10
Pass the number of elements first and ther size second, as expected by xcalloc(). Provide a semantic patch, which was actually used to generate the rest of this patch. The semantic patch would generate flip-flop diffs if both arguments are sizeofs. We don't have such a case, and it's hard to imagine the usefulness of such an allocation. If it ever occurs then we could deal with it by duplicating the rule in the semantic patch to make it cancel itself out, or we could change the code to use CALLOC_ARRAY.

2021-02-12Merge branch 'jk/complete-branch-force-delete'Libravatar Junio C Hamano1-2/+4
The command line completion (in contrib/) completed "git branch -d" with branch names, but "git branch -D" offered tagnames in addition, which has been corrected. "git branch -M" had the same problem. * jk/complete-branch-force-delete: doc/git-branch: fix awkward wording for "-c" completion: handle other variants of "branch -m" completion: treat "branch -D" the same way as "branch -d"
2021-02-03completion: handle other variants of "branch -m"Libravatar Jeff King1-2/+4
We didn't special-case "branch -M" (with a capital M) the same as "branch -m", nor any of the "--copy" variants. As a result these offered any ref as the next candidate, and not just branch names. Note that I rewrapped case-arm line since it's now quite long, and likewise the one below it for consistency. I also re-ordered the existing "-D" to make it more obvious how the cases group together.

2021-02-02completion: treat "branch -D" the same way as "branch -d"Libravatar Jeff King1-1/+1

2021-01-23Remove support for v1 of the PCRE libraryLibravatar Ævar Arnfjörð Bjarmason1-4/+0
Remove support for using version 1 of the PCRE library. Its use has been discouraged by upstream for a long time, and it's in a bugfix-only state. Anyone who was relying on v1 in particular got a nudge to move to v2 in e6c531b808 (Makefile: make USE_LIBPCRE=YesPlease mean v2, not v1, 2018-03-11), which was first released as part of v2.18.0. With this the LIBPCRE2 test prerequisites is redundant to PCRE. But I'm keeping it for self-documentation purposes, and to avoid conflict with other in-flight PCRE patches. I'm also not changing all of our own "pcre2" names to "pcre", i.e. the inverse of 6d4b5747f0 (grep: change internal *pcre* variable & function names to be *pcre1*, 2017-05-25). I don't see the point, and it makes the history/blame harder to read. Maybe if there's ever a PCRE v3...

2021-01-04completion: add proper public __git_completeLibravatar Felipe Contreras1-7/+33
When __git_complete was introduced, it was meant to be temporarily, while a proper guideline for public shell functions was established (tentatively _GIT_complete), but since that never happened, people in the wild started to use __git_complete, even though it was marked as not public. Eight years is more than enough wait, let's mark this function as public, and make it a bit more user-friendly. So that instead of doing: __git_complete gk __gitk_main The user can do: __git_complete gk gitk And instead of: __git_complete gf _git_fetch Do: __git_complete gf git_fetch Backwards compatibility is maintained.

Hotfix for a recent breakage. * fc/zsh-completion: completion: bash: fix gitk alias regression completion: zsh: fix file completion regression
2020-12-07completion: bash: fix gitk alias regressionLibravatar Felipe Contreras1-1/+1
Long time ago when the _git_complete helper was introduced, _gitk was replaced with __gitk_main, and a placeholder for backwards compatibility pointing to __git_wrap_main_gitk was left in place. When "__git_complete gitk __gitk_main" was called, that created the __git_wrap__gitk_main helper, which is just basically "__git_func_wrap __gitk_main" plus `complete` options. Unfortunately the commit b0a4b2d257 (completion: add support for backwards compatibility, 2012-05-19) missed a previous instance of a call to _gitk in _git_gitk So, basically we had __git_wrap__git_main -> __git_func_wrap __git_main -> __git_complete_command gitk -> _git_gitk -> _gitk -> __git_wrap__gitk_main -> __git_func_wrap __gitk_main -> __gitk_main. There was never any need to call __git_func_wrap twice. Since _git_gitk is always called inside the wrapper, it can call __gitk_main directly. And then, in commit 441ecdab37 (completion: bash: remove old compat wrappers, 2020-10-27) _gitk was removed, which triggers the following error: _git_gitk:9: command not found: _gitk Let's call the correct function: __gitk_main.

2020-12-04cmake: determine list of extra built-ins dynamicallyLibravatar Johannes Schindelin1-4/+11
In 0a21d0e08902 (Makefile: mark git-maintenance as a builtin, 2020-12-01), we marked git-maintenance as a builtin in the Makefile, but forgot to do the same in `CMakeLists.txt`. Rather than always play catch-up and adjust `git_builtin_extra` manually, use the `BUILT_INS` definitions in the Makefile as authoritative source and generate `git_builtin_extra` dynamically.

2020-12-04ci(vs-build): stop passing the iconv library location explicitlyLibravatar Dennis Ameling1-1/+1
Something changed in `vcpkg` (which we use in our Visual C++ build to provide the dependencies such as libcurl) and our `vs-build` job started failing in CI. The reason is that we had a work-around in place to help CMake find iconv, and this work-around is neither needed nor does it work anymore.

2020-11-01git-prompt.sh: localize `option` in __git_ps1_show_upstreamLibravatar Sibo Dong1-0/+1
The variable 'option' is used in __git_ps1_show_upstream() without being localized. This clobbers the variable the user may be using for other purposes, which is bad. Luckily, $option is not used to carry information around in the script as a global variable. The use of it in this script has very limited scope (namely, only inside this function), so just declare that it is "local".
