The recent addition of status.branch started affecting what is shown when "git status --porcelain" is run by mistake.

2013-06-17wt-status: give better advice when cherry-pick is in progressLibravatar Ralf Thielow1-2/+4
When cherry-pick is in progress, 'git status' gives the advice to run "git commit" to finish the cherry-pick. However, this won't continue the sequencer, when picking a range of commits. Advise users to run "git cherry-pick --continue/--abort"; they work when picking a single commit as well.

2013-06-17status: do not depend on rebase reflog messagesLibravatar Ramkumar Ramachandra1-1/+4
b397ea4 (status: show more info than "currently not on any branch", 2013-03-13) attempted to make the output of 'git status' richer in the case of a detached HEAD. Before this patch, with a detached HEAD, we saw: $ git status # Not currently on any branch. But after the patch, we see: $ git checkout v1.8.2 $ git status # HEAD detached at v1.8.2. It works by digging the reflog for the most recent message of the form "checkout: moving from xxxx to yyyy". It then asserts that HEAD and "yyyy" are the same, and displays this message. When they aren't equal, it displays: $ git status # HEAD detached from fe11db. so that the user can see where the HEAD was first detached. In case of a rebase [-i] operation in progress, this message depends on the implementation of rebase writing "checkout: " messages to the reflog, but that is an implementation detail of "rebase". To remove this dependency so that rebase can be updated to write better reflog messages, replace this "HEAD detached from" message with: # rebase in progress; onto $ONTO Changes to the commit object name in the expected output for some of the tests shows that what the test expected "status" to show during "rebase -i" was not consistent with the output during a vanilla "rebase", which showed on top of what commit the series is being replayed. Now we consistently expect something meaningful to the end user. Signed-off-by: Ramkumar Ramachandra <artagnon@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2013-04-15dir.c: git-status --ignored: don't scan the work tree twiceLibravatar Karsten Blees1-13/+11
'git-status --ignored' still scans the work tree twice to collect untracked and ignored files, respectively. fill_directory / read_directory already supports collecting untracked and ignored files in a single directory scan. However, the DIR_COLLECT_IGNORED flag to enable this has some git-add specific side-effects (e.g. it doesn't recurse into ignored directories, so listing ignored files with --untracked=all doesn't work). The DIR_SHOW_IGNORED flag doesn't list untracked files and returns ignored files in dir_struct.entries[] (instead of dir_struct.ignored[] as DIR_COLLECT_IGNORED). DIR_SHOW_IGNORED is used all throughout git. We don't want to break the existing API, so lets introduce a new flag DIR_SHOW_IGNORED_TOO that lists untracked as well as ignored files similar to DIR_COLLECT_FILES, but will recurse into sub-directories based on the other flags as DIR_SHOW_IGNORED does. In dir.c::read_directory_recursive, add ignored files to either dir_struct.entries[] or dir_struct.ignored[] based on the flags. Also move the DIR_COLLECT_IGNORED case here so that filling result lists is in a common place. In wt-status.c::wt_status_collect_untracked, use the new flag and read results from dir_struct.ignored[]. Remove the extra fill_directory call. builtin/check-ignore.c doesn't call fill_directory, setting the git-add specific DIR_COLLECT_IGNORED flag has no effect here. Remove for clarity. Update API documentation to reflect the changes. Performance: with this patch, 'git-status --ignored' is typically as fast as 'git-status'.

2013-03-21wt-status: fix possible use of uninitialized variableLibravatar Jeff King1-1/+4
In wt_status_print_change_data, we accept a change_type flag that is meant to be either WT_STATUS_UPDATED or WT_STATUS_CHANGED. We then switch() on this value to set the local variable "status" for each case, but do not provide a fallback "default" label to the switch statement. As a result, the compiler realizes that "status" might be unset, and complains with a warning. To silence this warning, we use the "int status = status" trick. This is correct with the current code, as all callers provide one of the two expected change_type flags. However, it's also a maintenance trap, as there is nothing to prevent future callers from passing another flag, nor to document this assumption. Instead of using the "x = x" hack, let's handle the default case in the switch() statement with a die("BUG"). That tells the compiler and any readers of the code exactly what the function's input assumptions are. We could also convert the flag to an enum, which would provide a compile-time check on the function input. However, since these flags are part of a larger enum, that would make the code unnecessarily complex (we would have to make a new enum with just the two flags, and then convert it to the old enum for passing to sub-functions).

2013-03-16status: show more info than "currently not on any branch"Libravatar Nguyễn Thái Ngọc Duy1-4/+85
When a remote ref or a tag is checked out, HEAD is automatically detached. There is no user-friendly way to find out what ref is checked out in this case. This patch digs in reflog for this information and shows "HEAD detached from origin/master" or "HEAD detached at v1.8.0" instead of "currently not on any branch". When it cannot figure out the original ref, it shows an abbreviated SHA-1. "Currently not on any branch" would never display (unless reflog is pruned to near empty that the last checkout entry is lost).

2013-03-16wt-status: move strbuf into read_and_strip_branch()Libravatar Nguyễn Thái Ngọc Duy1-35/+30
The strbufs are placed outside read_and_strip_branch as a premature optimization: when it reads "refs/heads/foo" to strbuf and wants to return just "foo", it could do so without memory movement. In return the caller must not use the returned pointer after releasing strbufs, which own the buffers that contain the returned strings. It's a clumsy design. By moving strbufs into read_and_strip_branch(), the returned pointer always points to a malloc'd buffer or NULL. The pointer can be passed around and freed after use.

The typical use-case is starting a rebase, do something else, come back the day after, run "git status" or make a new commit and wonder what in the world's going on. Which branch is being rebased is probably the most useful tidbit to help, but the target may help too. Ideally, I would have loved to see "rebasing master on origin/master", but the target ref name is not stored during rebase, so this patch writes "rebasing master on a78c8c98b" as a half-measure to remind future users of that potential improvement.

Some users do want to write a line that begin with a pound sign, #, in their commit log message. Many tracking system recognise a token of #<bugid> form, for example.

Avoid such a line by rewrapping or indenting; and - Use --cleanup=whitespace but remove all the hint lines we add.

The current behavior of git-status is inconsistent and misleading. Especially when used with --untracked-files=all option: - files ignored in untracked directories will be missing from status output. - untracked files in committed yet ignored directories are also missing. - with --untracked-files=normal, untracked directories that contains only ignored files are dropped too. Make the behavior more consistent across all possible use cases: - "--ignored --untracked-files=normal" doesn't show each specific files but top directory. It instead shows untracked directories that only contains ignored files, and ignored tracked directories with untracked files. - "--ignored --untracked-files=all" shows all ignored files, either because it's in an ignored directory (tracked or untracked), or because the file is explicitly ignored.

2012-07-16status: color in-progress message like other header messagesLibravatar Jeff King1-2/+1
The "status" command recently learned to describe the in-progress operation in its long output format (e.g., rebasing, am, etc). This message gets its own slot in the color table, even though it is not configurable. As a result, if the user has set color.status.header to a non-default value, this message will not match (and cannot be made to match, as there is no config option). It is probably more sane to just color it like the rest of the text (i.e., just use color.status.header). This would not allow users to customize the color of this message independently, but they cannot do that with the current code anyway, and if somebody wants to build customizable colorization later, this patch does not make it much harder to do so.

2011-08-19color: delay auto-color decision until point of useLibravatar Jeff King1-1/+3
When we read a color value either from a config file or from the command line, we use git_config_colorbool to convert it from the tristate always/never/auto into a single yes/no boolean value. This has some timing implications with respect to starting a pager. If we start (or decide not to start) the pager before checking the colorbool, everything is fine. Either isatty(1) will give us the right information, or we will properly check for pager_in_use(). However, if we decide to start a pager after we have checked the colorbool, things are not so simple. If stdout is a tty, then we will have already decided to use color. However, the user may also have configured color.pager not to use color with the pager. In this case, we need to actually turn off color. Unfortunately, the pager code has no idea which color variables were turned on (and there are many of them throughout the code, and they may even have been manipulated after the colorbool selection by something like "--color" on the command line). This bug can be seen any time a pager is started after config and command line options are checked. This has affected "git diff" since 89d07f7 (diff: don't run pager if user asked for a diff style exit code, 2007-08-12). It has also affect the log family since 1fda91b (Fix 'git log' early pager startup error case, 2010-08-24). This patch splits the notion of parsing a colorbool and actually checking the configuration. The "use_color" variables now have an additional possible value, GIT_COLOR_AUTO. Users of the variable should use the new "want_color()" wrapper, which will lazily determine and cache the auto-color decision.

This lets us store more than just a bit flag for whether we want color; we can also store whether we want automatic colors. This can be useful for making the automatic-color decision closer to the point of use. This mostly just involves replacing DIFF_OPT_* calls with manipulations of the flag. The biggest exception is that calls to DIFF_OPT_TST must check for "o->use_color > 0", which lets an "unknown" value (i.e., the default) stay at "no color". In the previous code, a value of "-1" was not propagated at all. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
