Ævar Arnfjörð Bjarmason 2708ce62d2 branch: sort detached HEAD based on a flag
Change the ref-filter sorting of detached HEAD to check the
FILTER_REFS_DETACHED_HEAD flag, instead of relying on the ref
description filled-in by get_head_description() to start with "(",
which in turn we expect to ASCII-sort before any other reference.

For context, we'd like the detached line to appear first at the start
of "git branch -l", e.g.:

    $ git branch -l
    * (HEAD detached at <hash>)
      master

This doesn't change that, but improves on a fix made in
28438e84e0 (ref-filter: sort detached HEAD lines firstly, 2019-06-18)
and gives the Chinese translation the ability to use its preferred
punctuation marks again.

In Chinese the fullwidth versions of punctuation like "()" are
typically written as (U+FF08 fullwidth left parenthesis), (U+FF09
fullwidth right parenthesis) instead[1]. This form is used in both
po/zh_{CN,TW}.po in most cases where "()" is translated in a string.

Aside from that improvement to the Chinese translation, it also just
makes for cleaner code that we mark any special cases in the ref_array
we're sorting with flags and make the sort function aware of them,
instead of piggy-backing on the general-case of strcmp() doing the
right thing.

As seen in the amended tests this made reverse sorting a bit more
consistent. Before this we'd sometimes sort this message in the
middle, now it's consistently at the beginning or end, depending on
whether we're doing a normal or reverse sort. Having it at the end
doesn't make much sense either, but at least it behaves consistently
now. A follow-up commit will make this behavior under reverse sorting
even better.

I'm removing the "TRANSLATORS" comments that were in the old code
while I'm at it. Those were added in d4919bb288 (ref-filter: move
get_head_description() from branch.c, 2017-01-10). I think it's
obvious from context, string and translation memory in typical
translation tools that these are the same or similar string.

Martin Ågren 962dd7ebc3 wt-status: introduce wt_status_state_free_buffers()
When we have a `struct wt_status_state`, we manually free its `branch`,
`onto` and `detached_from`, or sometimes just one or two of them.
Provide a function `wt_status_state_free_buffers()` which does the
freeing.

The callers are still aware of these fields, e.g., they check whether
`branch` was populated or not. But this way, they don't need to know
about *all* of them, and if `struct wt_status_state` gets more fields,
they will not need to learn to free them.

Users of `struct wt_status` (which contains a `wt_status_state`) already
have `wt_status_collect_free_buffers()` (corresponding to
`wt_status_collect()`) which we can also teach to use this new helper.

Finally, note that we're currently leaving dangling pointers behind.
Some callers work on a stack-allocated struct, where this is obviously
ok. But for the users of `run_status()` in builtin/commit.c, there are
ample opportunities for someone to mistakenly use those dangling
pointers. We seem to be ok for now, but it's a use-after-free waiting to
happen. Let's leave NULL-pointers behind instead.

Martin Ågren 8f7e3de097 wt-status: print to s->fp, not stdout
We pass around a `FILE *` in the `struct wt_status` and almost always
print to it. But in a few places, we write to `stdout` instead, either
explicitly through `fprintf(stdout, ...)` or implicitly with
`printf(...)` (and a few `putchar(...)`).

Always be explicit about writing to `s->fp`. To the best of my
understanding, this never mattered in practice because these spots are
involved in various forms of `git status` which always end up at
standard output anyway. When we do write to another file, it's because
we're creating a commit message template, and these code paths aren't
involved.

But let's be consistent to help future readers and avoid future bugs.

Junio C Hamano 0df670bc0b Merge branch 'jt/interpret-branch-name-fallback'
"git status" has trouble showing where it came from by interpreting
reflog entries that recordcertain events, e.g. "checkout @{u}", and
gives a hard/fatal error.  Even though it inherently is impossible
to give a correct answer because the reflog entries lose some
information (e.g. "@{u}" does not record what branch the user was
on hence which branch 'the upstream' needs to be computed, and even
if the record were available, the relationship between branches may
have changed), at least hide the error to allow "status" show its
output.

  wt-status: tolerate dangling marks

2020-09-09 13:53:09 -07:00
Jonathan Tan f24c30e0b6 wt-status: tolerate dangling marks
When a user checks out the upstream branch of HEAD, the upstream branch
not being a local branch, and then runs "git status", like this:

  git clone $URL client
  cd client
  git checkout @{u}
  git status

no status is printed, but instead an error message:

  fatal: HEAD does not point to a branch

(This error message when running "git branch" persists even after
checking out other things - it only stops after checking out a branch.)

This is because "git status" reads the reflog when determining the "HEAD
detached" message, and thus attempts to DWIM "@{u}", but that doesn't
work because HEAD no longer points to a branch.

Therefore, when calculating the status of a worktree, tolerate dangling
marks. This is done by adding an additional parameter to
dwim_ref() and repo_dwim_ref().

Elijah Newren eceba53214 dir: fix problematic API to avoid memory leaks
The dir structure seemed to have a number of leaks and problems around
it.  First I noticed that parent_hashmap and recursive_hashmap were
being leaked (though Peff noticed and submitted fixes before me).  Then
I noticed in the previous commit that clear_directory() was only taking
responsibility for a subset of fields within dir_struct, despite the
fact that entries[] and ignored[] we allocated internally to dir.c.
That, of course, resulted in many callers either leaking or haphazardly
trying to free these arrays and their contents.

Digging further, I found that despite the pretty clear documentation
near the top of dir.h that folks were supposed to call clear_directory()
when the user no longer needed the dir_struct, there were four callers
that didn't bother doing that at all.  However, two of them clearly
thought about leaks since they had an UNLEAK(dir) directive, which to me
suggests that the method to free the data was too unclear.  I suspect
the non-obviousness of the API and its holes led folks to avoid it,
which then snowballed into further problems with the entries[],
ignored[], parent_hashmap, and recursive_hashmap problems.

Rename clear_directory() to dir_clear() to be more in line with other
data structures in git, and introduce a dir_init() to handle the
suggested memsetting of dir_struct to all zeroes.  I hope that a name
like "dir_clear()" is more clear, and that the presence of dir_init()
will provide a hint to those looking at the code that they need to look
for either a dir_clear() or a dir_free() and lead them to find
dir_clear().

Elijah Newren dad4f23ce5 dir: make clear_directory() free all relevant memory
The calling convention for the dir API is supposed to end with a call to
clear_directory() to free up no longer needed memory.  However,
clear_directory() didn't free dir->entries or dir->ignored.  I believe
this was an oversight, but a number of callers noticed memory leaks and
started free'ing these.  Unfortunately, they did so somewhat haphazardly
(sometimes freeing the entries in the arrays, and sometimes only
free'ing the arrays themselves).  This suggests the callers weren't
trying to make sure any possible memory used might be free'd, but just
the memory they noticed their usecase definitely had allocated.

Fix this mess by moving all the duplicated free'ing logic into
clear_directory().  End by resetting dir to a pristine state so it could
be reused if desired.

Jeff King f6d8942b1f strvec: fix indentation in renamed calls
Code which split an argv_array call across multiple lines, like:

  argv_array_pushl(&args, "one argument",
                   "another argument", "and more",
		   NULL);

was recently mechanically renamed to use strvec, which results in
mis-matched indentation like:

  strvec_pushl(&args, "one argument",
                   "another argument", "and more",
		   NULL);

Let's fix these up to align the arguments with the opening paren. I did
this manually by sifting through the results of:

  git jump grep 'strvec_.*,$'

and liberally applying my editor's auto-format. Most of the changes are
of the form shown above, though I also normalized a few that had
originally used a single-tab indentation (rather than our usual style of
aligning with the open paren). I also rewrapped a couple of obvious
cases (e.g., where previously too-long lines became short enough to fit
on one), but I wasn't aggressive about it. In cases broken to three or
more lines, the grouping of arguments is sometimes meaningful, and it
wasn't worth my time or reviewer time to ponder each case individually.

Jeff King c972bf4cf5 strvec: convert remaining callers away from argv_array name
We eventually want to drop the argv_array name and just use strvec
consistently. There's no particular reason we have to do it all at once,
or care about interactions between converted and unconverted bits.
Because of our preprocessor compat layer, the names are interchangeable
to the compiler (so even a definition and declaration using different
names is OK).

This patch converts all of the remaining files, as the resulting diff is
reasonably sized.

The conversion was done purely mechanically with:

  git ls-files '*.c' '*.h' |
  xargs perl -i -pe '
    s/ARGV_ARRAY/STRVEC/g;
    s/argv_array/strvec/g;
  '

We'll deal with any indentation/style fallouts separately.

Elijah Newren 95c11ecc73 Fix error-prone fill_directory() API; make it only return matches
Traditionally, the expected calling convention for the dir.c API was:

    fill_directory(&dir, ..., pathspec)
    foreach entry in dir->entries:
        if (dir_path_match(entry, pathspec))
            process_or_display(entry)

This may have made sense once upon a time, because the fill_directory() call
could use cheap checks to avoid doing full pathspec matching, and an external
caller may have wanted to do other post-processing of the results anyway.
However:

    * this structure makes it easy for users of the API to get it wrong

    * this structure actually makes it harder to understand
      fill_directory() and the functions it uses internally.  It has
      tripped me up several times while trying to fix bugs and
      restructure things.

    * relying on post-filtering was already found to produce wrong
      results; pathspec matching had to be added internally for multiple
      cases in order to get the right results (see commits 404ebceda0
      (dir: also check directories for matching pathspecs, 2019-09-17)
      and 89a1f4aaf7 (dir: if our pathspec might match files under a
      dir, recurse into it, 2019-09-17))

    * it's bad for performance: fill_directory() already has to do lots
      of checks and knows the subset of cases where it still needs to do
      more checks.  Forcing external callers to do full pathspec
      matching means they must re-check _every_ path.

So, add the pathspec matching within the fill_directory() internals, and
remove it from external callers.

cases* except for when using Chinese-language messages. zh_CN generally
uses a full-width "(" symbol (codepoint FF08) to match the full-width
proportions of Chinese characters, and the translated strings we had did
use them. This meant that the detached HEAD line would appear after all
local refs and even after the remote refs if there were any.

AFAIK, it is sometimes not jarring to see the half-width parenthesis in
"full-width" text as in the CJK languages, for instance when there are
no characters preceding or following the parenthesized text fragment. By
removing the parenthesis from the localizable text, we can share strings
with wt-status.c and remove a cautionary comment to translators.

Remove the ( from the localizable portion of messages so the sorting
happens properly regardless of locale.

Jeff King 13a178129f wt-status: drop unused status parameter
The v2_fix_up_changed() function doesn't actually need to see the
wt_status struct. It's possible that could change in the future, but
this is a static-local function with one caller. It would be easy to
read-add it back then. Let's drop the unused parameter.

Nguyễn Thái Ngọc Duy 80f537f79c doc: promote "git restore"
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)

Denton Liu d540b70c85 merge: cleanup messages like commit
This change allows git-merge messages to be cleaned up with the
commit.cleanup configuration or --cleanup option, just like how
git-commit does it.

We also give git-pull the option of --cleanup so that it can also take
advantage of this change.

Finally, add testing to ensure that messages are properly cleaned up.
Note that some newlines that were added to the commit message were
removed so that if a file were read via -F, it would be copied
faithfully.

Damien Robert c646d0934e ref-filter: use correct branch for %(push:track)
In ref-filter.c, when processing the atom %(push:track), the
ahead/behind values are computed using `stat_tracking_info` which refers
to the upstream branch.

Fix that by introducing a new flag `for_push` in `stat_tracking_info`
in remote.c, which does the same thing but for the push branch.
Update the few callers of `stat_tracking_info` to handle this flag. This
ensure that whenever we use this function in the future, we are careful
to specify is this should apply to the upstream or the push branch.

This bug was not detected in t/t6300-for-each-ref.sh because in the test
for push:track, both the upstream and the push branches were behind by 1
from the local branch. Change the test so that the upstream branch is
behind by 1 while the push branch is ahead by 1. This allows us to test
that %(push:track) refers to the correct branch.

This changes the expected value of some following tests (by introducing
new references), so update them too.

Since `git rebase -r` was introduced, that is possible. But our
machinery did not think that possible, and failed to say anything about
the rebase in progress when in the middle of a merge.

Let's work around that in the minimal fashion.
