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.

In an update to fix a bug with "commit --dry-run" it was found that

Since the setting of the committable flag had been done in
wt_longstatus_print_updated, move it to wt_status_collect_updated_cb.
Set the committable flag in wt_status_collect_changes_initial to keep

Instead of setting the committable flag in show_merge_in_progress, in
wt_status_cllect check for a merge that has not been committed. If
present then set the committable flag.
Change the tests to expect success since updates to the wt-status

Using the more restrictive oideq() should, in the long run,
give the compiler more opportunities to optimize these
callsites. For now, this conversion should be a complete
noop with respect to the generated code.
The result is also perhaps a little more readable, as it
avoids the "zero is equal" idiom. Since it's so prevalent in
C, I think seasoned programmers tend not to even notice it
anymore, but it can sometimes make for awkward double
negations (e.g., we can drop a few !!oidcmp() instances
here).
This patch was generated almost entirely by the included
coccinelle patch. This mechanical conversion should be
completely safe, because we check explicitly for cases where
oidcmp() is compared to 0, which is what oideq() is doing
under the hood. Note that we don't have to catch "!oidcmp()"
separately; coccinelle's standard isomorphisms make sure the
two are treated equivalently.
I say "almost" because I did hand-edit the coccinelle output
to fix up a few style violations (it mostly keeps the
original formatting, but sometimes unwraps long lines).

If has_uncommitted_changes() can't resolve HEAD (e.g.,
because it's unborn or corrupt), then we end up calling
run_diff_index() with an empty revs.pending array. This
causes a segfault, as run_diff_index() blindly looks at the
first pending item.
Fixing this raises a question of fault: should
run_diff_index() handle this case, or is the caller wrong to
pass an empty pending list?
Looking at the other callers of run_diff_index(), they
handle this in one of three ways:
- they resolve the object themselves, and avoid doing the
diff if it's not valid
- they resolve the object themselves, and fall back to the
empty tree
- they use setup_revisions(), which will die() if the
object isn't valid
Since this is the only broken caller, that argues that the
fix should go there. Falling back to the empty tree makes
sense here, as we'd claim uncommitted changes if and only if
the index is non-empty. This may be a little funny in the
case of corruption (the corrupt HEAD probably _isn't_
empty), but:
- we don't actually know the reason here that HEAD didn't
resolve (the much more likely case is that we have an
unborn HEAD, in which case the empty tree comparison is
the right thing)
- this matches how other code, like "git diff", behaves
While we're thinking about it, let's add an assertion to
run_diff_index(). It should always be passed a single
object, and as this bug shows, it's easy to get it wrong
(and an assertion is easier to hunt down than a segfault, or
a quietly ignored extra tree).

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

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.

detection during status and commit. This setting will default to the value
of diff.renames.

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:

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.

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.

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.

"git interpret-trailers" is unaware of the cut line, and assumes the

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).
