2021-06-15subtree: fix assumption about the directory separatorLibravatar Johannes Schindelin1-3/+4
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.

2021-06-02contrib/completion: fix zsh completion regression from 59d85a2a05Libravatar David Aguilar2-2/+2
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. In addition to the undefined variable usage, "git mv <tab>" also prints the following error: __git_count_arguments:7: bad math expression: operand expected at `"1"' _git_mv:[:7: unknown condition: -gt Remove the quotes around $__git_cmd_idx in __git_count_arguments and set __git_cmd_idx=1 early in __git_zsh_main to fix the regressions from 59d85a2a05.

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: parse revs in individual cmd_ functionsLibravatar Luke Shumaker1-38/+24
The main argument parser goes ahead and tries to parse revs to make things simpler for the sub-command implementations. But, it includes enough special cases for different sub-commands. And it's difficult having having to think about "is this info coming from an argument, or a global variable?". So the main argument parser's effort to make things "simpler" ends up just making it more confusing and complicated. Begone with the 'revs' global variable; parse 'rev=$(...)' as needed in individual 'cmd_*' functions. Begone with the 'default' global variable. Its would-be value is knowable just from which function we're in. Begone with the 'ensure_single_rev' function. Its functionality can be achieved by passing '--verify' to 'git rev-parse'.

2021-04-28subtree: don't fuss with PATHLibravatar Luke Shumaker1-2/+16
Scripts needing to fuss with with adding $(git --exec-prefix) PATH before loading git-sh-setup is a thing of the past. As far as I can tell, it's been a thing of the past since since Git v1.2.0 (2006-02-12), or more specifically, since 77cb17e940 (Exec git programs without using PATH, 2006-01-10). However, it stuck around in contrib scripts and in third-party scripts for long enough that it wasn't unusual to see. Originally `git subtree` didn't fuss with PATH, but when people (including the original subtree author) had problems, because it was a common thing to see, it seemed that having subtree fuss with PATH was a reasonable solution. Here is an abridged history of fussing with PATH in subtree: 2987e6add3 (Add explicit path of git installation by 'git --exec-path', Gianluca Pacchiella, 2009-08-20) As pointed out by documentation, the correct use of 'git-sh-setup' is using $(git --exec-path) to avoid problems with not standard installations. -. git-sh-setup +. $(git --exec-path)/git-sh-setup 33aaa697a2 (Improve patch to use git --exec-path: add to PATH instead, Avery Pennarun, 2009-08-26) If you (like me) are using a modified git straight out of its source directory (ie. without installing), then --exec-path isn't actually correct. Add it to the PATH instead, so if it is correct, it'll work, but if it's not, we fall back to the previous behaviour. -. $(git --exec-path)/git-sh-setup +PATH=$(git --exec-path):$PATH +. git-sh-setup 9c632ea29c ((Hopefully) fix PATH setting for msysgit, Avery Pennarun, 2010-06-24) Reported by Evan Shaw. The problem is that $(git --exec-path) includes a 'git' binary which is incompatible with the one in /usr/bin; if you run it, it gives you an error about libiconv2.dll. +OPATH=$PATH PATH=$(git --exec-path):$PATH . git-sh-setup +PATH=$OPATH # apparently needed for some versions of msysgit df2302d774 (Another fix for PATH and msysgit, Avery Pennarun, 2010-06-24) Evan Shaw tells me the previous fix didn't work. Let's use this one instead, which he says does work. This fix is kind of wrong because it will run the "correct" git-sh-setup *after* the one in /usr/bin, if there is one, which could be weird if you have multiple versions of git installed. But it works on my Linux and his msysgit, so it's obviously better than what we had before. -OPATH=$PATH -PATH=$(git --exec-path):$PATH +PATH=$PATH:$(git --exec-path) . git-sh-setup -PATH=$OPATH # apparently needed for some versions of msysgit First of all, I disagree with Gianluca's reading of the documentation: - I haven't gone back to read what the documentation said in 2009, but in my reading of the 2021 documentation is that it includes "$(git --exec-path)/" in the synopsis for illustrative purposes, not to say it's the proper way. - After being executed by `git`, the git exec path should be the very first entry in PATH, so it shouldn't matter. - None of the scripts that are part of git do it that way. But secondly, the root reason for fussing with PATH seems to be that Avery didn't know that he needs to set GIT_EXEC_PATH if he's going to use git from the source directory without installing. And finally, Evan's issue is clearly just a bug in msysgit. I assume that msysgit has since fixed the issue, and also msysgit has been deprecated for 6 years now, so let's drop the workaround for it. So, remove the line fussing with PATH. However, since subtree *is* in 'contrib/' and it might get installed in funny ways by users after-the-fact, add a sanity check to the top of the script, checking that it is installed correctly.

2021-04-28subtree: use "$*" instead of "$@" as appropriateLibravatar Luke Shumaker1-3/+3
"$*" is for when you want to concatenate the args together, whitespace-separated; and "$@" is for when you want them to be separate strings. There are several places in subtree that erroneously use $@ when concatenating args together into an error message. For instance, if the args are argv[1]="dead" and argv[2]="beef", then the line die "You must provide exactly one revision. Got: '$@'" surely intends to call 'die' with the argument argv[1]="You must provide exactly one revision. Got: 'dead beef'" however, because the line used $@ instead of $*, it will actually call 'die' with the arguments argv[1]="You must provide exactly one revision. Got: 'dead" argv[2]="beef'" This isn't a big deal, because 'die' concatenates its arguments together anyway (using "$*"). But that doesn't change the fact that it was a mistake to use $@ instead of $*, even though in the end $@ still ended up doing the right thing.

Suport for Git versions older than 1.7.0 (older than February 2010) was nice to have when git-subtree lived out-of-tree. But now that it lives in git.git, it's not necessary to keep around. While it's technically in contrib, with the standard 'git' packages for common systems (including Arch Linux and macOS) including git-subtree, it seems vanishingly likely to me that people are separately installing git-subtree from git.git alongside an older 'git' install (although it also seems vanishingly likely that people are still using >11 year old git installs). Not that there's much reason to remove it either, it's not much code, and none of my changes depend on a newer git (to my knowledge, anyway; I'm not actually testing against older git). I just figure it's an easy piece of fat to trim, in the journey to making the whole thing easier to hack on. "Ignore space change" is probably helpful when viewing this diff.

Shove all of the loose code inside of a main() function. This comes down to personal preference more than anything else.

2021-04-28subtree: t7900: rename last_commit_message to last_commit_subjectLibravatar Luke Shumaker1-13/+13
t7900-subtree.sh defines a helper function named last_commit_message. However, it only returns the subject line of the commit message, not the entire commit message. So rename it, to make the name less confusing. Signed-off-by: Luke Shumaker <lukeshu@datawire.io> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2021-04-28subtree: t7900: fix 'verify one file change per commit'Libravatar Luke Shumaker1-40/+6
As far as I can tell, this test isn't actually testing anything, because someone forgot to tack on `--name-only` to `git log`. This seems to have been the case since the test was first written, back in fa16ab36ad ("test.sh: make sure no commit changes more than one file at a time.", 2009-04-26), unless `git log` used to do that by default and didn't need the flag back then? Convincing myself that it's not actually testing anything was tricky, the code is a little hard to reason about. It can be made a lot simpler if instead of trying to parse all of the info from a single `git log`, we're OK calling `git log` from inside of a loop. And it's my opinion that tests are not the place for clever optimized code. So, fix and simplify the test, so that it's actually testing something and is simpler to reason about.

t7900-subtree.sh defines its own `check_equal A B` function, instead of just using `test A = B` like all of the other tests. Don't be special, get rid of `check_equal` in favor of `test`. Signed-off-by: Luke Shumaker <lukeshu@datawire.io> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2021-04-28subtree: t7900: comment subtree_test_create_repoLibravatar Luke Shumaker1-6/+8
It's unclear what the purpose of t7900-subtree.sh's `subtree_test_create_repo` helper function is. It wraps test-lib.sh's, `test_create_repo` but follows that up by setting log.date=relative. Why does it set log.date=relative? My first guess was that at one point the tests required that, but no longer do, and that the function is now vestigial. I even wrote a patch to get rid of it and was moments away from `git send-email`ing it. However, by chance when looking for something else in the history, I discovered the true reason, from e7aac44ed2 (contrib/subtree: ignore log.date configuration, 2015-07-21). It's testing that setting log.date=relative doesn't break `git subtree`, as at one point in the past that did break `git subtree`. So, add a comment about this, to avoid future such confusion. And while at it, go ahead and (1) touch up the function to avoid a pointless subshell and (2) update the one test that didn't use it.
