Many messages will be marked for translation in the following commits. This commit updates some of them to be more consistent and reduce diff noise in those commits. Changes are - keep the first letter of die(), error() and warning() in lowercase - no full stop in die(), error() or warning() if it's single sentence messages - indentation - some messages are turned to BUG(), or prefixed with "BUG:" and will not be marked for i18n - some messages are improved to give more information - some messages are broken down by sentence to be i18n friendly (on the same token, combine multiple warning() into one big string) - the trailing \n is converted to printf_ln if possible, or deleted if not redundant - errno_errno() is used instead of explicit strerror() Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2018-05-29help: add --config to list all available configLibravatar Nguyễn Thái Ngọc Duy1-0/+3
Sometimes it helps to list all available config vars so the user can search for something they want. The config man page can also be used but it's harder to search if you want to focus on the variable name, for example. This is not the best way to collect the available config since it's not precise. Ideally we should have a centralized list of config in C code (pretty much like 'struct option'), but that's a lot more work. This will do for now.

Migrate all git_path_* functions that are defined in path.c to take a repository argument. Unlike other patches in this series, do not use the #define trick, as we rewrite the whole function, which is rather small. This doesn't migrate all the functions, as other builtins have their own local path functions defined using GIT_PATH_FUNC. So keep that macro around to serve the other locations.

2018-05-13add status config and command line options for rename detectionLibravatar Ben Peart1-0/+42
After performing a merge that has conflicts git status will, by default, attempt to detect renames which causes many objects to be examined. In a virtualized repo, those objects do not exist locally so the rename logic triggers them to be fetched from the server. This results in the status call taking hours to complete on very large repos vs seconds with this patch. Add a new config status.renames setting to enable turning off rename detection during status and commit. This setting will default to the value of diff.renames. Add a new config status.renamelimit setting to to enable bounding the time spent finding out inexact renames during status and commit. This setting will default to the value of diff.renamelimit. Add --no-renames command line option to status that enables overriding the config setting from the command line. Add --find-renames[=<n>] command line option to status that enables detecting renames and optionally setting the similarity index.

2018-05-06Replace all die("BUG: ...") calls by BUG() onesLibravatar Johannes Schindelin1-1/+1
In d8193743e08 (usage.c: add BUG() function, 2017-05-12), a new macro was introduced to use for reporting bugs instead of die(). It was then subsequently used to convert one single caller in 588a538ae55 (setup_git_env: convert die("BUG") to BUG(), 2017-05-12). The cover letter of the patch series containing this patch (cf 20170513032414.mfrwabt4hovujde2@sigill.intra.peff.net) is not terribly clear why only one call site was converted, or what the plan is for other, similar calls to die() to report bugs. Let's just convert all remaining ones in one fell swoop.

2018-05-06wt-status: use settings from git_diff_ui_configLibravatar Eckhard S. Maaß1-1/+1
If you do something like - git add . - git status - git commit - git show (or git diff HEAD) one would expect to have analogous output from git status and git show (or similar diff-related programs). This is generally not the case, as git status has hard coded values for diff related options. With this commit the hard coded settings are dropped from the status command in favour for values provided by git_diff_ui_config. What follows are some remarks on the concrete options which were hard coded in git status: diffopt.detect_rename Since the very beginning of git status in a3e870f2e2 ("Add "commit" helper script", 2005-05-30), git status always used rename detection, whereas with commands like show and log one had to activate it with a command line option. After 5404c116aa ("diff: activate diff.renames by default", 2016-02-25) the default behaves the same by coincidence, but changing diff.renames to other values can break the consistency between git status and other commands again. With this commit one control the same default behaviour with diff.renames. diffopt.rename_limit Similarly one has the option diff.renamelimit to adjust this limit for all commands but git status. With this commit git status will also honor those. diffopt.break_opt Unlike the other two options this cannot be configured by a configuration option yet. This commit will also change the default behaviour to not use break rewrites. But as rename detection is most likely on, this is dangerous to be activated anyway as one can see here: https://public-inbox.org/git/xmqqegqaahnh.fsf@gitster.dls.corp.google.com/ Signed-off-by: Eckhard S.

Commit 8894d53580 (commit: allow partial commits with relative paths, 2011-07-30) ensured that partial commits were allowed when a user supplies a relative pathspec but then this was regressed in 5879f5684c (remove prefix argument from pathspec_prefix, 2011-09-04) when the prefix argument to 'pathspec_prefix' removed and the 'list_paths' function wasn't properly adjusted to cope with the change, resulting in over-eager pruning of the tree that is overlayed on the index. This fixes the regression and adds a regression test so this can be prevented in the future. Signed-off-by: Brandon Williams <bmwill@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2018-03-01write_locked_index(): add flag to avoid writing unchanged indexLibravatar Martin Ågren1-7/+3
We have several callers like if (active_cache_changed && write_locked_index(...)) handle_error(); rollback_lock_file(...); where the final rollback is needed because "!active_cache_changed" shortcuts the if-expression. There are also a few variants of this, including some if-else constructs that make it more clear when the explicit rollback is really needed. Teach `write_locked_index()` to take a new flag SKIP_IF_UNCHANGED and simplify the callers. Leave the most complicated of the callers (in builtin/update-index.c) unchanged. Rewriting it to use this new flag would end up duplicating logic. We could have made the new flag behave the other way round ("FORCE_WRITE"), but that could break existing users behind their backs. Let's take the more conservative approach. We can still migrate existing callers to use our new flag. Later we might even be able to flip the default, possibly without entirely ignoring the risk to in-flight or out-of-tree topics.

2018-03-01commit: run git gc --auto just before the post-commit hookLibravatar Ævar Arnfjörð Bjarmason1-0/+2
Change the behavior of git-commit back to what it was back in d4bb43ee27 ("Invoke "git gc --auto" from commit, merge, am and rebase.", 2007-09-05) when it was git-commit.sh. Shortly afterwards in f5bbc3225c ("Port git commit to C.", 2007-11-08) when it was ported to C, the "git gc --auto" invocation went away. Since that unintended regression, git gc --auto only ran for git-am, git-merge, git-fetch, and git-receive-pack. It was possible to write a script that would "git commit" a lot of data locally, and gc would never run. One such repository that was locally committing generated zone file changes had grown to a size of ~60GB before a daily cronjob was added to "git gc", bringing it down to less than 1GB. This will make such cases work without intervention. I think fixing such pathological cases where the repository will grow forever is a worthwhile trade-off for spending a couple of milliseconds calling "git gc --auto" (in the common cases where it doesn't do anything).

2017-12-22commit: add support for --fixup <commit> -m"<extra message>"Libravatar Ævar Arnfjörð Bjarmason1-3/+5
Add support for supplying the -m option with --fixup. Doing so has errored out ever since --fixup was introduced. Before this, the only way to amend the fixup message while committing was to use --edit and amend it in the editor. The use-case for this feature is one of: * Leaving a quick note to self when creating a --fixup commit when it's not self-evident why the commit should be squashed without a note into another one. * (Ab)using the --fixup feature to "fix up" commits that have already been pushed to a branch that doesn't allow non-fast-forwards, i.e. just noting "this should have been part of that other commit", and if the history ever got rewritten in the future the two should be combined. In such a case you might want to leave a small message, e.g. "forgot this part, which broke XYZ". With this, --fixup <commit> -m"More" -m"Details" will result in a commit message like: !fixup <subject of <commit>> More Details The reason the test being added here seems to squash "More" at the end of the subject line of the commit being fixed up is because the test code is using "%s%b" so the body immediately follows the subject, it's not a bug in this code, and other tests t7500-commit.sh do the same thing. When the --fixup option was initially added the "Option -m cannot be combined" error was expanded from -c, -C and -F to also include --fixup[1] Those options could also support combining with -m, but given what they do I can't think of a good use-case for doing that, so I have not made the more invasive change of splitting up the logic in commit.c to first act on those, and then on -m options. 1. d71b8ba7c9 ("commit: --fixup option for use with rebase --autosquash", 2010-11-02) Helped-by: Eric Sunshine <sunshine@sunshineco.com> Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-11-24commit: move print_commit_summary() to libgitLibravatar Phillip Wood1-119/+9
Move print_commit_summary() from builtin/commit.c to sequencer.c so it can be shared with other commands. The function is modified by changing the last argument to a flag so callers can specify whether they want to show the author date in addition to specifying if this is an initial commit. If the sequencer dies in print_commit_summary() (which can only happen when cherry-picking or reverting) then neither the todo list nor the abort safety file are updated to reflect the commit that was just made. print_commit_summary() can die if: - The commit that was just created cannot be found or parsed. - HEAD cannot be resolved either because some other process is updating it (which is bad news in the middle of a cherry-pick) or because it is corrupt. - log_tree_commit() cannot read some objects. In all those cases dying will leave the sequencer in a sane state for aborting; 'git cherry-pick --abort' will rewind HEAD to the last successful commit before there was a problem with HEAD or the object database. If the user somehow fixes the problem and runs 'git cherry-pick --continue' then the sequencer will try and pick the same commit again which may or may not be what the user wants depending on what caused print_commit_summary() to die. If print_commit_summary() returned an error instead then update_abort_safety_file() would try to resolve HEAD which may or may not be successful. If it is successful then running 'git rebase --abort' would not rewind HEAD to the last successful commit which is not what we want.

2017-11-08reduce_heads: fix memory leaksLibravatar Martin Ågren1-1/+1
We currently have seven callers of `reduce_heads(foo)`. Six of them do not use the original list `foo` again, and actually, all six of those end up leaking it. Introduce and use `reduce_heads_replace(&foo)` as a leak-free version of `foo = reduce_heads(foo)` to fix several of these. Fix the remaining leaks using `free_commit_list()`. While we're here, document `reduce_heads()` and mark it as `extern`. Signed-off-by: Martin Ågren <martin.agren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2017-11-01diff: convert flags to be stored in bitfieldsLibravatar Brandon Williams1-3/+4
We cannot add many more flags to the diff machinery due to the limitations of the number of flags that can be stored in a single unsigned int. In order to allow for more flags to be added to the diff machinery in the future this patch converts the flags to be stored in bitfields in 'struct diff_flags'.

2017-10-31status: add option to show ignored files differentlyLibravatar Jameson Miller1-6/+25
Teach the status command more flexibility in how ignored files are reported. Currently, the reporting of ignored files and untracked files are linked. You cannot control how ignored files are reported independently of how untracked files are reported (i.e. `all` vs `normal`). This makes it impossible to show untracked files with the `all` option, but show ignored files with the `normal` option. This work 1) adds the ability to control the reporting of ignored files independently of untracked files and 2) introduces the concept of status reporting ignored paths that explicitly match an ignored pattern. There are 2 benefits to these changes: 1) if a consumer needs all untracked files but not all ignored files, there is a performance benefit to not scanning all contents of an ignored directory and 2) returning ignored files that explicitly match a path allow a consumer to make more informed decisions about when a status result might be stale. This commit implements --ignored=matching with --untracked-files=all. The following commit will implement --ignored=matching with --untracked=files=normal. As an example of where this flexibility could be useful is that our application (Visual Studio) runs the status command and presents the output. It shows all untracked files individually (e.g. using the '--untracked-files==all' option), and would like to know about which paths are ignored. It uses information about ignored paths to make decisions about when the status result might have changed. Additionally, many projects place build output into directories inside a repository's working directory (e.g. in "bin/" and "obj/" directories). Normal usage is to explicitly ignore these 2 directory names in the .gitignore file (rather than or in addition to the *.obj pattern).If an application could know that these directories are explicitly ignored, it could infer that all contents are ignored as well and make better informed decisions about files in these directories. It could infer that any changes under these paths would not affect the output of status. Additionally, there can be a significant performance benefit by avoiding scanning through ignored directories. When status is set to report matching ignored files, it has the following behavior. Ignored files and directories that explicitly match an exclude pattern are reported. If an ignored directory matches an exclude pattern, then the path of the directory is returned. If a directory does not match an exclude pattern, but all of its contents are ignored, then the contained files are reported instead of the directory.

2017-10-21commit: check result of resolve_ref_unsafeLibravatar Andrey Okoshkin1-0/+2
Add check of the resolved HEAD reference while printing of a commit summary. resolve_ref_unsafe() may return NULL pointer if underlying calls of lstat() or open() fail in files_read_raw_ref(). Such situation can be caused by race: file becomes inaccessible to this moment. Signed-off-by: Andrey Okoshkin <a.okoshkin@samsung.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2017-10-07read-cache: drop explicit `CLOSE_LOCK`-flagLibravatar Martin Ågren1-5/+5
`write_locked_index()` takes two flags: `COMMIT_LOCK` and `CLOSE_LOCK`. At most one is allowed. But it is also possible to use no flag, i.e., `0`. But when `write_locked_index()` calls `do_write_index()`, the temporary file, a.k.a. the lockfile, will be closed. So passing `0` is effectively the same as `CLOSE_LOCK`, which seems like a bug. We might feel tempted to restructure the code in order to close the file later, or conditionally. It also feels a bit unfortunate that we simply "happen" to close the lock by way of an implementation detail of lockfiles. But note that we need to close the temporary file before `stat`-ing it, at least on Windows. See 9f41c7a6b (read-cache: close index.lock in do_write_index, 2017-04-26). Drop `CLOSE_LOCK` and make it explicit that `write_locked_index()` always closes the lock. Whether it is also committed is governed by the remaining flag, `COMMIT_LOCK`. This means we neither have nor suggest that we have a mode to write the index and leave the file open. Whatever extra contents we might eventually want to write, we should probably write it from within `write_locked_index()` itself anyway.
