2019-08-07git-merge: honor pre-merge-commit hookLibravatar Michael J Gruber1-0/+13
git-merge does not honor the pre-commit hook when doing automatic merge commits, and for compatibility reasons this is going to stay. Introduce a pre-merge-commit hook which is called for an automatic merge commit just like pre-commit is called for a non-automatic merge commit (or any other commit). [js: * renamed hook from "pre-merge" to "pre-merge-commit" * only discard the index if the hook is actually present * expanded githooks documentation entry * clarified that hook should write messages to stderr * squashed test changes from the original series' patch 4/4 * modified tests to follow new pattern from this series' patch 1/4 * added a test case for non-executable merge hooks * added a test case for failed merges * when testing that the merge hook did not run, make sure we actually have a merge to perform (by resetting the "side" branch to its original state). * reworded commit message ] Improved-by: Martin Ågren <martin.agren@gmail.com> Signed-off-by: Michael J Gruber <git@grubix.eu> Signed-off-by: Martin Ågren <martin.agren@gmail.com> Signed-off-by: Josh Steadmon <steadmon@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-05-02Update shell scripts to compute empty tree object IDLibravatar brian m. carlson1-1/+1
Several of our shell scripts hard-code the object ID of the empty tree. To avoid any problems when changing hashes, compute this value on startup of the script. For performance, store the value in a variable and reuse it throughout the life of the script.

2017-11-10fsmonitor: read from getcwd(), not the PWD environment variableLibravatar Alex Vandiver1-1/+2
Though the process has chdir'd to the root of the working tree, the PWD environment variable is only guaranteed to be updated accordingly if a shell is involved -- which is not guaranteed to be the case. That is, if `/usr/bin/perl` is a binary, $ENV{PWD} is unchanged from whatever spawned `git` -- if `/usr/bin/perl` is a trivial shell wrapper to the real `perl`, `$ENV{PWD}` will have been updated to the root of the working copy. Update to read from the Cwd module using the `getcwd` syscall, not the PWD environment variable. The Cygwin case is left unchanged, as it necessarily _does_ go through a shell.

2017-10-30fsmonitor: don't bother pretty-printing JSON from watchmanLibravatar Alex Vandiver1-1/+1
This provides modest performance savings. Benchmarking with the following program, with and without `--no-pretty`, we find savings of 23% (0.316s -> 0.242s) in the git repository, and savings of 8% (5.24s -> 4.86s) on a large repository with 580k files in the working copy. #!/usr/bin/perl use strict; use warnings; use IPC::Open2; use JSON::XS; my $pid = open2(\*CHLD_OUT, \*CHLD_IN, "watchman -j @ARGV") or die "open2() failed: $!\n" . "Falling back to scanning...\n"; my $query = qq|["query", "$ENV{PWD}", {}]|; print CHLD_IN $query; close CHLD_IN; my $response = do {local $/; <CHLD_OUT>}; JSON::XS->new->utf8->decode($response); Signed-off-by: Alex Vandiver <alexmv@dropbox.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-10-04fsmonitor: read entirety of watchman outputLibravatar Alex Vandiver1-4/+2
In Perl, setting $/ sets the string that is used as the "record separator," which sets the boundary that the `<>` construct reads to. Setting `local $/ = 0666;` evaluates the octal, getting 438, and stringifies it. Thus, the later read from `<CHLD_OUT>` stops as soon as it encounters the string "438" in the watchman output, yielding invalid JSON; repositories containing filenames with SHA1 hashes are able to trip this easily. Set `$/` to undefined, thus slurping all output from watchman. Also close STDIN which is provided to watchman, to better guarantee that we cannot deadlock with watchman while both attempting to read.

Follow the Oxford style, which says to use "up-to-date" before the noun, but "up to date" after it. Don't change plumbing (specifically send-pack.c, but transport.c (git push) also has the same string). This was produced by grepping for "up-to-date" and "up to date".

2017-07-12hook: add sign-off using "interpret-trailers"Libravatar Kaartic Sivaraam1-1/+5
The sample hook to prepare the commit message before a commit allows users to opt-in to add the sign-off to the commit message. The sign-off is added at a place that isn't consistent with the "-s" option of "git commit". Further, it could go out of view in certain cases. Add the sign-off in a way similar to "-s" option of "git commit" using git's interpret-trailers command. It works well in all cases except when the user invokes "git commit" without any arguments. In that case manually add a new line after the first line to ensure it's consistent with the output of "-s" option.

2016-07-14push options: {pre,post}-receive hook learns about push optionsLibravatar Stefan Beller1-0/+24
The environment variable GIT_PUSH_OPTION_COUNT is set to the number of push options sent, and GIT_PUSH_OPTION_{0,1,..} is set to the transmitted option. The code is not executed as the push options are set to NULL, nor is the new capability advertised. There was some discussion back and forth how to present these push options to the user as there are some ways to do it: Keep all options in one environment variable ============================================ + easiest way to implement in Git - This would make things hard to parse correctly in the hook. Put the options in files instead, filenames are in GIT_PUSH_OPTION_FILES ====================================== + After a discussion about environment variables and shells, we may not want to put user data into an environment variable (see [1] for example). + We could transmit binaries, i.e. we're not bound to C strings as we are when using environment variables to the user. + Maybe easier to parse than constructing environment variable names GIT_PUSH_OPTION_{0,1,..} yourself - cleanup of the temporary files is hard to do reliably - we have race conditions with multiple clients pushing, hence we'd need to use mkstemp. That's not too bad, but still. Use environment variables, but restrict to key/value pairs ========================================================== (When the user pushes a push option `foo=bar`, we'd GIT_PUSH_OPTION_foo=bar) + very easy to parse for a simple model of push options - it's not sufficient for more elaborate models, e.g. it doesn't allow doubles (e.g. cc=reviewer@email) Present the options in different environment variables ====================================================== (This is implemented) * harder to parse as a user, but we have a sample hook for that. - doesn't allow binary files + allows the same option twice, i.e. is not restrictive about options, except for binary files. + doesn't clutter a remote directory with (possibly stale) temporary files As we first want to focus on getting simple strings to work reliably, we go with the last option for now. If we want to do transmission of binaries later, we can just attach a 'side-channel', e.g. "any push option that contains a '\0' is put into a file instead of the environment variable and we'd have new GIT_PUSH_OPTION_FILES, GIT_PUSH_OPTION_FILENAME_{0,1,..} environment variables".

2014-12-22pre-push.sample: remove unnecessary and misleading IFS=' 'Libravatar Jim Hill1-1/+0
The sample hook explicitly sets IFS to SP and nothing else so that the "read" used in the per-ref while loop that iterates over "<localref> SP <localsha1> SP <remoteref> SP <remotesha>" records, where we know refs and sha1s will not have SPs, would split them correctly. While this is not wrong per-se, it is not necessary; because we know these fields do not contain HT or LF, either, we can simply leave IFS the default. This will also prevent those who cut and paste from this sample from getting bitten when they write things in the per-ref loop that need splitting with the default $IFS (e.g. use $(git rev-list ...) to produce one-record-per-line output).
