The --[no-]ahead-behind option was introduced in fd9b544a (status: add --[no-]ahead-behind to status and commit for V2 format, 2018-01-09). This is a necessary change of behavior in repos where the remote tracking branches can move very quickly ahead of the local branches.

2019-06-12commit-graph: collapse parameters into flagsLibravatar Derrick Stolee1-1/+1
The write_commit_graph() and write_commit_graph_reachable() methods currently take two boolean parameters: 'append' and 'report_progress'.

2019-06-12commit-graph: return with errors during writeLibravatar Derrick Stolee1-2/+3
The write_commit_graph() method uses die() to report failure and exit when confronted with an unexpected condition. This use of die() in a library function is incorrect and is now replaced by error() statements and an int return type. Return zero on success and a negative value on failure. Now that we use 'goto cleanup' to jump to the terminal condition on an error, we have new paths that could lead to uninitialized values. New initializers are added to correct for this. The builtins 'commit-graph', 'gc', and 'commit' call these methods, so update them to check the return value. Test that 'git commit-graph write' returns a proper error code when hitting a failure condition in write_commit_graph().

2019-05-07doc: promote "git restore"Libravatar Nguyễn Thái Ngọc Duy1-1/+1
The new command "git restore" (together with "git switch") are added to avoid the confusion of one-command-do-all "git checkout" for new users. They are also helpful to avoid ambiguous context. For these reasons, promote it everywhere possible. This includes documentation, suggestions/advice from other commands. One nice thing about git-restore is the ability to restore "everything", so it can be used in "git status" advice instead of both "git checkout" and "git reset". The three commands suggested by "git status" are add, rm and restore. "git checkout" is also removed from "git help" (i.e. it's no longer considered a commonly used command) Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2019-04-17commit/reset: try to clean up sequencer stateLibravatar Phillip Wood1-2/+1
When cherry-picking or reverting a sequence of commits and if the final pick/revert has conflicts and the user uses `git commit` to commit the conflict resolution and does not run `git cherry-pick --continue` then the sequencer state is left behind. This can cause problems later. In my case I cherry-picked a sequence of commits the last one of which I committed with `git commit` after resolving some conflicts, then a while later, on a different branch I aborted a revert which rewound my HEAD to the end of the cherry-pick sequence on the previous branch. Avoid this potential problem by removing the sequencer state if we're committing or resetting the final pick in a sequence.

2019-02-04config: allow giving separate author and committer identsLibravatar William Hubbs1-1/+2
The author.email, author.name, committer.email and committer.name settings are analogous to the GIT_AUTHOR_* and GIT_COMMITTER_* environment variables, but for the git config system. This allows them to be set separately for each repository. Git supports setting different authorship and committer information with environment variables. However, environment variables are set in the shell, so if different authorship and committer information is needed for different repositories an external tool is required. This adds support to git config for author.email, author.name, committer.email and committer.name settings so this information can be set per repository. Also, it generalizes the fmt_ident function so it can handle author vs committer identification. Signed-off-by: William Hubbs <williamh@gentoo.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2019-01-11commit: copy saved getenv() resultLibravatar Jeff King1-1/+2
We save the result of $GIT_INDEX_FILE so that we can restore it after setting it to a new value and running add--interactive. However, the pointer returned by getenv() is not guaranteed to be valid after calling setenv(). This _usually_ works fine, but can fail if libc needs to reallocate the environment block during the setenv(). Let's just duplicate the string, so we know that it remains valid. In the long run it may be more robust to teach interactive_add() to take a set of environment variables to pass along to run-command when it execs add--interactive. And then we would not have to do this save/restore dance at all. But this is an easy fix in the meantime. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2018-11-06assert NOARG/NONEG behavior of parse-options callbacksLibravatar Jeff King1-0/+3
When we define a parse-options callback, the flags we put in the option struct must match what the callback expects. For example, a callback which does not handle the "unset" parameter should only be used with PARSE_OPT_NONEG. But since the callback and the option struct are not defined next to each other, it's easy to get this wrong (as earlier patches in this series show). Fortunately, the compiler can help us here: compiling with -Wunused-parameters can show us which callbacks ignore their "unset" parameters (and likewise, ones that ignore "arg" expect to be triggered with PARSE_OPT_NOARG). But after we've inspected a callback and determined that all of its callers use the right flags, what do we do next? We'd like to silence the compiler warning, but do so in a way that will catch any wrong calls in the future. We can do that by actually checking those variables and asserting that they match our expectations. Because this is such a common pattern, we'll introduce some helper macros. The resulting messages aren't as descriptive as we could make them, but the file/line information from BUG() is enough to identify the problem (and anyway, the point is that these should never be seen). Each of the annotated callbacks in this patch triggers -Wunused-parameters, and was manually inspected to make sure all callers use the correct options (so none of these BUGs should be triggerable).

If you run "git status --no-find-renames", it will behave the same as "--find-renames", because we ignore the "unset" parameter (we see a NULL "arg", but since the score argument is optional, we just think that the user did not provide a score). We already have a separate "--no-renames" to disable renames, so there's not much point in supporting "--no-find-renames". Let's just flag it as an error.

2018-10-03roll wt_status_state into wt_status and populate in the collect phaseLibravatar Stephen P. Smith1-0/+3
Status variables were initialized in the collect phase and some variables were later freed in the print functions. A "struct wt_status" used to be sufficient for the output phase to work. It was designed to be filled in the collect phase and consumed in the output phase, but over time some fields were added and output phase started filling the fields. A "struct wt_status_state" that was used in other codepaths turned out to be useful in the "git status" output. This is not tied to "struct wt_status", so filling in the collect phase was not consistently followed. Move the status state structure variables into the status state structure and populate them in the collect functions. Create a new function to free the buffers that were being freed in the print function. Call this new function in commit.c where both the collect and print functions were being called.

2018-09-27commit: fix erroneous BUG, 'multiple renames on the same target? how?'Libravatar Elijah Newren1-0/+1
builtin/commit.c:prepare_to_commit() can call run_status() twice if using the editor, including status, and the user attempts to record a non-merge empty commit without explicit --allow-empty. If there is also a rename involved as well (due to using 'git add -N'), then a BUG in wt-status.c is triggered: BUG: wt-status.c:476: multiple renames on the same target? how? The reason we hit this bug is that both run_status() calls use the same struct wt_status * (named s), and s->change is not freed between runs. Changes are inserted into s with string_list_insert, which usually means that the second run just recomputes all the same results and overwrites what was computed the first time. However, ever since commit 176ea7479309 ("wt-status.c: handle worktree renames", 2017-12-27), wt-status started checking for renames and copies but also added a preventative check that d->rename_status wasn't already set and output a BUG message if it was. The problem isn't that there are multiple rename targets to a single path as the error implies, the problem is that 's' is not freed/cleared between the two run_status() calls. Ever since commit dc6b1d92ca9c ("wt-status: use settings from git_diff_ui_config", 2018-05-04), which stopped hardcoding DIFF_DETECT_RENAME and allowed users to ask for copy detection, this bug has also been triggerable with a copy instead of a rename. Fix the bug by clearing s->change. A better change might be to clean up all of s between the two run_status() calls. A good first step towards such a goal might be writing a function to free the necessary fields in the wt_status * struct; a cursory glance at the code suggests all of its allocated data is probably leaked. However, doing all that cleanup is a bigger task for someone else interested to tackle; just fix the bug for now.

2018-09-21rerere.c: remove implicit dependency on the_indexLibravatar Nguyễn Thái Ngọc Duy1-1/+1
The reason rerere(), rerere_forget() and rerere_remaining() take a struct repository instead of struct index_state is not obvious from the patch: Deep in update_paths() and find_conflict(), hold_locked_index() and read_index() are called. These functions assumes the index path at $GIT_DIR/index which is not always true when you take an arbitrary index state. Taking a repository will allow us to point to the right index path later when we replace them with repo_ versions.
