2021-08-18completion: bash: add correct suffix in variablesLibravatar Felipe Contreras1-3/+3
__gitcomp automatically adds a suffix, but __gitcomp_nl and others don't, we need to specify a space by default. Can be tested with: git config branch.autoSetupMe<tab> This fix only works for versions of bash greater than 4.0, before that "local sfx" creates an empty string, therefore the unset expansion doesn't work. The same happens in zsh. Therefore we don't add the test for that for now. The correct fix for all shells requires semantic changes in __gitcomp, but that can be done later.

2021-06-28cmake(windows): set correct path to the system Git configLibravatar Dennis Ameling1-4/+7
Currently, when Git for Windows is built with CMake, the system Git config is expected in a different location than when building via `make`: the former expects it to be in `<runtime-prefix>/mingw64/etc/gitconfig`, the latter in `<runtime-prefix>/etc/gitconfig`. Because of this, things like `git clone` do not work correctly (because cURL is no longer able to find its certificate bundle that it needs to validate HTTPS certificates). See the full bug report and discussion here: https://github.com/git-for-windows/git/issues/3071#issuecomment-789261386. This commit aligns the CMake-based build by mimicking what is already done in `config.mak.uname`. This closes https://github.com/git-for-windows/git/issues/3071.

On Windows, both forward and backslash are valid separators. In 22d550749361 (subtree: don't fuss with PATH, 2021-04-27), however, we added code that assumes that it can only be the forward slash.

2021-06-15subtree: fix the GIT_EXEC_PATH sanity check to work on WindowsLibravatar Johannes Schindelin1-1/+4
In 22d550749361 (subtree: don't fuss with PATH, 2021-04-27), `git subtree` was broken thoroughly on Windows. The reason is that it assumes Unix semantics, where `PATH` is colon-separated, and it assumes that `$GIT_EXEC_PATH:` is a verbatim prefix of `$PATH`. Neither are true, the latter in particular because `GIT_EXEC_PATH` is a Windows-style path, while `PATH` is a Unix-style path list. Let's make extra certain that `$GIT_EXEC_PATH` and the first component of `$PATH` refer to different entities before erroring out. We do that by using the `test <path1> -ef <path2>` command that verifies that the inode of `<path1>` and of `<path2>` is the same. Sadly, this construct is non-portable, according to https://pubs.opengroup.org/onlinepubs/009695399/utilities/test.html. However, it does not matter in practice because we still first look whether `$GIT_EXEC_PREFIX` is string-identical to the first component of `$PATH`. This will give us the expected result everywhere but in Git for Windows, and Git for Windows' own Bash _does_ handle the `-ef` operator. Just in case that we _do_ need to show the error message _and_ are running in a shell that lacks support for `-ef`, we simply suppress the error output for that part.

2021-06-11cmake: create compile_commands.json by defaultLibravatar Matthew Rogers1-0/+4
Some users have expressed interest in a more "batteries included" way of building via CMake[1], and a big part of that is providing easier access to tooling external tools. A straightforward way to accomplish this is to make it as simple as possible is to enable the generation of the compile_commands.json file, which is supported by many tools such as: clang-tidy, clang-format, sourcetrail, etc. This does come with a small run-time overhead during the configuration step (~6 seconds on my machine): Time to configure with CMAKE_EXPORT_COMPILE_COMMANDS=TRUE real 1m9.840s user 0m0.031s sys 0m0.031s Time to configure with CMAKE_EXPORT_COMPILE_COMMANDS=FALSE real 1m3.195s user 0m0.015s sys 0m0.015s This seems like a small enough price to pay to make the project more accessible to newer users. Additionally there are other large projects like llvm [2] which has had this enabled by default for >6 years at the time of this writing, and no real negative consequences that I can find with my search-skills. NOTE: That the compile_commands.json is currently produced only when using the Ninja and Makefile generators. See The CMake documentation[3] for more info. 1: https://lore.kernel.org/git/CAOjrSZusMSvs7AS-ZDsV8aQUgsF2ZA754vSDjgFKMRgi_oZAWw@mail.gmail.com/ 2: https://github.com/llvm/llvm-project/commit/2c5712051b31b316a9fc972f692579bd8efa6e67 3: https://cmake.org/cmake/help/latest/variable/CMAKE_EXPORT_COMPILE_COMMANDS.html Signed-off-by: Matthew Rogers <mattr94@gmail.com> Acked-by: Johannes Schindelin <Johannes.Schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2021-06-11cmake: add knob to disable vcpkgLibravatar Matthew Rogers1-4/+15
When building on windows users have the option to use vcpkg to provide the dependencies needed to compile. Previously, this was used only when using the Visual Studio generator which was not ideal because: - Not all users who want to use vcpkg use the Visual Studio generators. - Some versions of Visual Studio 2019 moved away from using the VS 2019 generator by default, making it impossible for Visual Studio to configure the project in the likely event that it couldn't find the dependencies. - Inexperienced users of CMake are very likely to get tripped up by the errors caused by a lack of vcpkg, making the above bullet point both annoying and hard to debug. As such, let's make using vcpkg the default on windows. Users who want to avoid using vcpkg can disable it by passing -DNO_VCPKG=TRUE.

A recent change to make git-completion.bash use $__git_cmd_idx in more places broke a number of completions on zsh because it modified __git_main but did not update __git_zsh_main. Notably, completions for "add", "branch", "mv" and "push" were broken as a result of this change.

2021-04-28subtree: allow --squash to be used with --rejoinLibravatar Luke Shumaker3-24/+96
Besides being a genuinely useful thing to do, this also just makes sense and harmonizes which flags may be used when. `git subtree split --rejoin` amounts to "automatically go ahead and do a `git subtree merge` after doing the main `git subtree split`", so it's weird and arbitrary that you can't pass `--squash` to `git subtree split --rejoin` like you can `git subtree merge`. It's weird that `git subtree split --rejoin` inherits `git subtree merge`'s `--message` but not `--squash`. Reconcile the situation by just having `split --rejoin` actually just call `merge` internally (or call `add` instead, as appropriate), so it can get access to the full `merge` behavior, including `--squash`.

2021-04-28subtree: give the docs a once-overLibravatar Luke Shumaker3-93/+87
Just went through the docs looking for anything inaccurate or that can be improved. In the '-h' text, in the man page synopsis, and in the man page description: Normalize the ordering of the list of sub-commands: 'add', 'merge', 'split', 'pull', 'push'. This allows us to kinda separate the lower-level add/merge/split from the higher-level pull/push. '-h' text: - correction: Indicate that split's arg is optional. - clarity: Emphasize that 'pull' takes the 'add'/'merge' flags. man page: - correction: State that all subcommands take options (it seemed to indicate that only 'split' takes any options other than '-P'). - correction: 'split' only guarantees that the results are identical if the flags are identical. - correction: The flag is named '--ignore-joins', not '--ignore-join'. - completeness: Clarify that 'push' always operates on HEAD, and that 'split' operates on HEAD if no local commit is given. - clarity: In the description, when listing commands, repeat what their arguments are. This way the reader doesn't need to flip back and forth between the command description and the synopsis and the full description to understand what's being said. - clarity: In the <variables> used to give command arguments, give slightly longer, descriptive names. Like <local-commit> instead of just <commit>. - clarity: Emphasize that 'pull' takes the 'add'/'merge' flags. - style: In the synopsis, list options before the subcommand. This makes things line up and be much more readable when shown non-monospace (such as in `make html`), and also more closely matches other man pages (like `git-submodule.txt`). - style: Use the correct syntax for indicating the options ([<options>] instead of [OPTIONS]). - style: In the synopsis, separate 'pull' and 'push' from the other lower-level commands. I think this helps readability. - style: Code-quote things in prose that seem like they should be code-quoted, like '.gitmodules', flags, or full commands. - style: Minor wording improvements, like more consistent mood (many of the command descriptions start in the imperative mood and switch to the indicative mode by the end). That sort of thing. - style: Capitalize "ID". - style: Remove the "This option is only valid for XXX command" remarks from each option, and instead rely on the section headings. - style: Since that line is getting edited anyway, switch "behaviour" to American "behavior". - style: Trim trailing whitespace. `todo`: - style: Trim trailing whitespace.

2021-04-28subtree: have $indent actually affect indentationLibravatar Luke Shumaker1-18/+24
Currently, the $indent variable is just used to track how deeply we're nested, and the debug log is indented by things like debug " foo" That is: The indentation-level is hard-coded. It used to be that the code couldn't recurse, so the indentation level could be known statically, so it made sense to just hard-code it in the output. However, since 315a84f9aa ("subtree: use commits before rejoins for splits", 2018-09-28), it can now recurse, and the debug log is misleading. So fix that. Indent according to $indent.

2021-04-28subtree: don't let debug and progress output clashLibravatar Luke Shumaker1-1/+21
Currently, debug output (triggered by passing '-d') and progress output stomp on each other. The debug output is just streamed as lines to stderr, and the progress output is sent to stderr as '%s\r'. When writing to a file, it is awkward to read and difficult to distinguish between the debug output and a progress line. When writing to a terminal the debug lines hide progress lines. So, when '-d' has been passed, spit out progress as 'progress: %s\n', instead of as '%s\r', so that it can be detected, and so that the debug lines don't overwrite the progress when written to a terminal.

2021-04-28subtree: add comments and sanity checksLibravatar Luke Shumaker1-3/+61
For each function in subtree, add a usage comment saying what the arguments are, and add an `assert` checking the number of arguments. In figuring out each thing's arguments in order to write those comments and assertions, it turns out that find_existing_splits is written as if it takes multiple 'revs', but it is in fact only ever passed a single 'rev': unrevs="$(find_existing_splits "$dir" "$rev")" || exit $? So go ahead and codify that by documenting and asserting that it takes exactly two arguments, one dir and one rev.

2021-04-28subtree: remove duplicate checkLibravatar Luke Shumaker1-4/+0
`cmd_add` starts with a check that the directory doesn't yet exist. However, the `main` function performs the exact same check before calling `cmd_add`. So remove the check from `cmd_add`. Signed-off-by: Luke Shumaker <lukeshu@datawire.io> Signed-off-by: Junio C Hamano <gitster@pobox.com>
