2018-03-08Merge branch 'jh/status-no-ahead-behind'Libravatar Junio C Hamano1-12/+29
"git status" can spend a lot of cycles to compute the relation between the current branch and its upstream, which can now be disabled with "--no-ahead-behind" option. * jh/status-no-ahead-behind: status: support --no-ahead-behind in long format status: update short status to respect --no-ahead-behind status: add --[no-]ahead-behind to status and commit for V2 format. stat_tracking_info: return +1 when branches not equal

Teach "git status" and "git commit" to accept "--no-ahead-behind" and "--ahead-behind" arguments to request quick or full ahead/behind reporting. When "--no-ahead-behind" is given, the existing porcelain V2 line "branch.ab +x -y" is replaced with a new "branch.ab +? -?" line. This indicates that the branch and its upstream are or are not equal without the expense of computing the full ahead/behind values.

2018-01-24stat_tracking_info: return +1 when branches not equalLibravatar Jeff Hostetler1-2/+4
Extend stat_tracking_info() to return +1 when branches are not equal and to take a new "enum ahead_behind_flags" argument to allow skipping the (possibly expensive) ahead/behind computation. This will be used in the next commit to allow "git status" to avoid full ahead/behind calculations for performance reasons.

"git status" after moving a path in the working tree (hence making it appear "removed") and then adding with the -N option (hence making that appear "added") detected it as a rename, but did not report the old and new pathnames correctly. * nd/ita-wt-renames-in-status: wt-status.c: handle worktree renames wt-status.c: rename rename-related fields in wt_status_change_data wt-status.c: catch unhandled diff status codes wt-status.c: coding style fix Use DIFF_DETECT_RENAME for detect_rename assignments t2203: test status output with porcelain v2 format
2017-12-27wt-status.c: handle worktree renamesLibravatar Nguyễn Thái Ngọc Duy1-3/+19
Before 425a28e0a4 (diff-lib: allow ita entries treated as "not yet exist in index" - 2016-10-24) there are never "new files" in the index, which essentially disables rename detection because we only detect renames when a new file appears in a diff pair. After that commit, an i-t-a entry can appear as a new file in "git diff-files". But the diff callback function in wt-status.c does not handle this case and produces incorrect status output. PS. The reader may notice that this patch adds a new xstrdup() but not a free(). Yes we leak memory (the same for head_path). But wt_status so far has been short lived, this leak should not matter in practice.

2017-11-07wt-status: actually ignore submodules when requestedLibravatar Brandon Williams1-1/+3
Since ff6f1f564 (submodule-config: lazy-load a repository's .gitmodules file, 2017-08-03) rebase interactive fails if there are any submodules with unstaged changes which have been configured with a value for 'submodule.<name>.ignore' in the repository's config. This is due to how configured values of 'submodule.<name>.ignore' are handled in addition to a change in how the submodule config is loaded. When the diff machinery hits a submodule (gitlink as well as a corresponding entry in the submodule subsystem) it will read the value of 'submodule.<name>.ignore' stored in the repository's config and if the config is present it will clear the 'IGNORE_SUBMODULES' (which is the flag explicitly requested by rebase interactive), 'IGNORE_UNTRACKED_IN_SUBMODULES', and 'IGNORE_DIRTY_SUBMODULES' diff flags and then set one of them based on the configured value. Historically this wasn't a problem because the submodule subsystem wasn't initialized because the .gitmodules file wasn't explicitly loaded by the rebase interactive command. So when the diff machinery hit a submodule it would skip over reading any configured values of 'submodule.<name>.ignore'. In order to preserve the behavior of submodules being ignored by rebase interactive, also set the 'OVERRIDE_SUBMODULE_CONFIG' diff flag when submodules are requested to be ignored when checking for unstaged changes.

2017-10-31status: add option to show ignored files differentlyLibravatar Jameson Miller1-3/+8
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.

It's not good to use the phrase 'do not touch' to convey the information that the cut-line should not be modified or removed as it could possibly be mis-interpreted by a person who doesn't know that the word 'touch' has the meaning of 'tamper with'. Further, it could make translations a little difficult as it might not have the intended meaning in a few languages when translated as such. So, use more intuitive terms in the sentence.

"git status" has long shown essentially the same message as "git commit"; the message it gives while preparing for the root commit, i.e. "Initial commit", was hard to understand for some new users.

2017-06-21status: contextually notify user about an initial commitLibravatar Kaartic Sivaraam1-2/+5
The existing message, "Initial commit", makes sense for the commit template notifying users that it's their initial commit, but is confusing when merely checking the status of a fresh repository (or orphan branch) without having any commits yet. Change the output of "status" to say "No commits yet" when "git status" is run on a fresh repo (or orphan branch), while retaining the current "Initial commit" message displayed in the template that's displayed in the editor when the initial commit is being authored. Correspondingly change the output of "short status" to "No commits yet on " when "git status -sb" is run on a fresh repo (or orphan branch). A few alternatives considered were, * Waiting for initial commit * Your current branch does not have any commits * Current branch waiting for initial commit The most succint one among the alternatives was chosen.

Because the function ignore_non_trailer() used by the command takes a <pointer, length> pair, not a strbuf, steal the logic from wt_status_truncate_message_at_cut_line() to create a new wt_status_locate_end() helper function that takes <pointer, length> pair, and make ignore_non_trailer() call it to help "interpret-trailers". Since there is only one caller of wt_status_truncate_message_at_cut_line() in cmd_commit(), rewrite it to call wt_status_locate_end() helper instead and remove the old helper that no longer has any caller.

2017-05-16Merge branch 'js/larger-timestamps'Libravatar Junio C Hamano1-1/+1
Some platforms have ulong that is smaller than time_t, and our historical use of ulong for timestamp would mean they cannot represent some timestamp that the platform allows. Invent a separate and dedicated timestamp_t (so that we can distingiuish timestamps and a vanilla ulongs, which along is already a good move), and then declare uintmax_t is the type to be used as the timestamp_t. * js/larger-timestamps: archive-tar: fix a sparse 'constant too large' warning use uintmax_t for timestamps date.c: abort if the system time cannot handle one of our timestamps timestamp_t: a new data type for timestamps PRItime: introduce a new "printf format" for timestamps parse_timestamp(): specify explicitly where we parse timestamps t0006 & t5000: skip "far in the future" test when time_t is too limited t0006 & t5000: prepare for 64-bit timestamps ref-filter: avoid using `unsigned long` for catch-all data type
2017-05-08Convert lookup_commit* to struct object_idLibravatar brian m. carlson1-1/+1
Convert lookup_commit, lookup_commit_or_die, lookup_commit_reference, and lookup_commit_reference_gently to take struct object_id arguments. Introduce a temporary in parse_object buffer in order to convert this function. This is required since in order to convert parse_object and parse_object_buffer, lookup_commit_reference_gently and lookup_commit_or_die would need to be converted. Not introducing a temporary would therefore require that lookup_commit_or_die take a struct object_id *, but lookup_commit would take unsigned char *, leaving a confusing and hard-to-use interface. parse_object_buffer will lose this temporary in a later patch.

2017-05-08split_commit_in_progress(): simplify & fix memory leakLibravatar Johannes Schindelin1-14/+14
This function did a whole lot of unnecessary work, such as reading in four files just to figure out that, oh, hey, we do not need to look at them after all because the HEAD is not detached. Simplify the entire function to return early when possible, to read in the files only when necessary, and to release the allocated memory always (there was a leak, reported via Coverity, where we failed to release the allocated strings if the HEAD is not detached).

2017-04-28status: fix missing newline when comment chars are disabledLibravatar Jeff King1-1/+1
When git-status shows tracking data for the current branch in the long format, we try to end the stanza with a blank line. When status.displayCommentPrefix is true, we call color_fprintf_ln() to do so. But when it's false, we call the enigmatic: fputs("", s->fp); which does nothing at all! This is a bug from 7d7d68022 (silence a bunch of format-zero-length warnings, 2014-05-04). Prior to that, we called fprintf_ln() with an empty string. Switching to fputs() meant we needed to include the "newline in the string, but we didn't. So you see: On branch jk/status-tracking-newline Your branch is ahead of 'origin/master' by 1 commit. Changes not staged for commit: modified: foo Untracked files: bar whereas there should be a blank line before the "Changes not staged" line. The fix itself is a one-liner. But we never noticed this bug because t7508 doesn't exercise the ahead/behind code at all. So let's configure an upstream during the initial setup, which means that the code will be exercised as part of all of the various invocations in that script. This makes the diff rather noisy, but should give us good coverage. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-04-27timestamp_t: a new data type for timestampsLibravatar Johannes Schindelin1-1/+1
Git's source code assumes that unsigned long is at least as precise as time_t. Which is incorrect, and causes a lot of problems, in particular where unsigned long is only 32-bit (notably on Windows, even in 64-bit versions). So let's just use a more appropriate data type instead. In preparation for this, we introduce the new `timestamp_t` data type. By necessity, this is a very, very large patch, as it has to replace all timestamps' data type in one go. As we will use a data type that is not necessarily identical to `time_t`, we need to be very careful to use `time_t` whenever we interact with the system functions, and `timestamp_t` everywhere else.

2017-03-29short status: improve reporting for submodule changesLibravatar Stefan Beller1-2/+15
If I add an untracked file to a submodule or modify a tracked file, currently "git status --short" treats the change in the same way as changes to the current HEAD of the submodule: $ git clone --quiet --recurse-submodules https://gerrit.googlesource.com/gerrit $ echo hello >gerrit/plugins/replication/stray-file $ sed -i -e 's/.*//' gerrit/plugins/replication/.mailmap $ git -C gerrit status --short M plugins/replication This is by analogy with ordinary files, where "M" represents a change that has not been added yet to the index. But this change cannot be added to the index without entering the submodule, "git add"-ing it, and running "git commit", so the analogy is counterproductive. Introduce new status letters " ?" and " m" for this. These are similar to the existing "??" and " M" but mean that the submodule (not the parent project) has new untracked files and modified files, respectively. The user can use "git add" and "git commit" from within the submodule to add them. Changes to the submodule's HEAD commit can be recorded in the index with a plain "git add -u" and are shown with " M", like today. To avoid excessive clutter, show at most one of " ?", " m", and " M" for the submodule. They represent increasing levels of change --- the last one that applies is shown (e.g., " m" if there are both modified files and untracked files in the submodule, or " M" if the submodule's HEAD has been modified and it has untracked files). While making these changes, we need to make sure to not break porcelain level 1, which shares code with "status --short". We only change "git status --short". Non-short "git status" and "git status --porcelain=2" already handle these cases by showing more detail: $ git -C gerrit status --porcelain=2 1 .M S.MU 160000 160000 160000 305c864db28eb0c77c8499bc04c87de3f849cf3c 305c864db28eb0c77c8499bc04c87de3f849cf3c plugins/replication $ git -C gerrit status [...] modified: plugins/replication (modified content, untracked content) Scripts caring about these distinctions should use --porcelain=2.
