f6ef8baba2 Merge branch 'ph/use-delete-refs'
When removing many branches and tags, the code used to do so one
ref at a time.  There is another API it can use to delete multiple
refs, and it makes quite a lot of performance difference when the
refs are packed.

bca362c1f9 completion: handle other variants of "branch -m"
We didn't special-case "branch -M" (with a capital M) the same as
"branch -m", nor any of the "--copy" variants. As a result these offered
any ref as the next candidate, and not just branch names.

Note that I rewrapped case-arm line since it's now quite long, and
likewise the one below it for consistency. I also re-ordered the
existing "-D" to make it more obvious how the cases group together.

5c327502db MacOS: precompose_argv_prefix()
The following sequence leads to a "BUG" assertion running under MacOS:

  DIR=git-test-restore-p
  Adiarnfd=$(printf 'A\314\210')
  DIRNAME=xx${Adiarnfd}yy
  mkdir $DIR &&
  cd $DIR &&
  git init &&
  mkdir $DIRNAME &&
  cd $DIRNAME &&
  echo "Initial" >file &&
  git add file &&
  echo "One more line" >>file &&
  echo y | git restore -p .

 Initialized empty Git repository in /tmp/git-test-restore-p/.git/
 BUG: pathspec.c:495: error initializing pathspec_item
 Cannot close git diff-index --cached --numstat
 [snip]

The command `git restore` is run from a directory inside a Git repo.
Git needs to split the $CWD into 2 parts:
The path to the repo and "the rest", if any.
"The rest" becomes a "prefix" later used inside the pathspec code.

As an example, "/path/to/repo/dir-inside-repå" would determine
"/path/to/repo" as the root of the repo, the place where the
configuration file .git/config is found.

The rest becomes the prefix ("dir-inside-repå"), from where the
pathspec machinery expands the ".", more about this later.
If there is a decomposed form, (making the decomposing visible like this),
"dir-inside-rep°a" doesn't match "dir-inside-repå".

Git commands need to:

 (a) read the configuration variable "core.precomposeunicode"
 (b) precocompose argv[]
 (c) precompose the prefix, if there was any

The first commit,
76759c7dff "git on Mac OS and precomposed unicode"
addressed (a) and (b).

The call to precompose_argv() was added into parse-options.c,
because that seemed to be a good place when the patch was written.

Commands that don't use parse-options need to do (a) and (b) themselfs.

The commands `diff-files`, `diff-index`, `diff-tree` and `diff`
learned (a) and (b) in
commit 90a78b83e0 "diff: run arguments through precompose_argv"

Branch names (or refs in general) using decomposed code points
resulting in decomposed file names had been fixed in
commit 8e712ef6fc "Honor core.precomposeUnicode in more places"

The bug report from above shows 2 things:
- more commands need to handle precomposed unicode
- (c) should be implemented for all commands using pathspecs

Solution:
precompose_argv() now handles the prefix (if needed), and is renamed into
precompose_argv_prefix().

Inside this function the config variable core.precomposeunicode is read
into the global variable precomposed_unicode, as before.
This reading is skipped if precomposed_unicode had been read before.

The original patch for preocomposed unicode, 76759c7dff, placed
precompose_argv() into parse-options.c

Now add it into git.c::run_builtin() as well.  Existing precompose
calls in diff-files.c and others may become redundant, and if we
audit the callflows that reach these places to make sure that they
can never be reached without going through the new call added to
run_builtin(), we might be able to remove these existing ones.

But in this commit, we do not bother to do so and leave these
precompose callsites as they are.  Because precompose() is
idempotent and can be called on an already precomposed string
safely, this is safer than removing existing calls without fully
vetting the callflows.

There is certainly room for cleanups - this change intends to be a bug fix.
Cleanups needs more tests in e.g. t/t3910-mac-os-precompose.sh, and should
be done in future commits.

076b444a62 worktree: teach list verbose mode
"git worktree list" annotates each worktree according to its state such
as "prunable" or "locked", however it is not immediately obvious why
these worktrees are being annotated. For prunable worktrees a reason
is available that is returned by should_prune_worktree() and for locked
worktrees a reason might be available provided by the user via `lock`
command.

Let's teach "git worktree list" a --verbose mode that outputs the reason
why the worktrees are being annotated. The reason is a text that can take
virtually any size and appending the text on the default columned format
will make it difficult to extend the command with other annotations and
not fit nicely on the screen. In order to address this shortcoming the
annotation is then moved to the next line indented followed by the reason
If the reason is not available the annotation stays on the same line as
the worktree itself.

The output of "git worktree list" with verbose becomes like so:

    $ git worktree list --verbose
    ...
    /path/to/locked-no-reason    acb124 [branch-a] locked
    /path/to/locked-with-reason  acc125 [branch-b]
        locked: worktree with a locked reason
    /path/to/prunable-reason     ace127 [branch-d]
        prunable: gitdir file points to non-existent location
    ...

9b19a58f66 worktree: teach list to annotate prunable worktree
The "git worktree list" command shows the absolute path to the worktree,
the commit that is checked out, the name of the branch, and a "locked"
annotation if the worktree is locked, however, it does not indicate
whether the worktree is prunable.

The "prune" command will remove a worktree if it is prunable unless
`--dry-run` option is specified. This could lead to a worktree being
removed without the user realizing before it is too late, in case the
user forgets to pass --dry-run for instance. If the "list" command shows
which worktree is prunable, the user could verify before running
"git worktree prune" and hopefully prevents the working tree to be
removed "accidentally" on the worse case scenario.

Let's teach "git worktree list" to show when a worktree is a prunable
candidate for both default and porcelain format.

In the default format a "prunable" text is appended:

    $ git worktree list
    /path/to/main      aba123 [main]
    /path/to/linked    123abc [branch-a]
    /path/to/prunable  ace127 (detached HEAD) prunable

In the --porcelain format a prunable label is added followed by
its reason:

    $ git worktree list --porcelain
    ...
    worktree /path/to/prunable
    HEAD abc1234abc1234abc1234abc1234abc1234abc12
    detached
    prunable gitdir file points to non-existent location
    ...

862c723d18 worktree: teach list --porcelain to annotate locked worktree
Commit c57b3367be (worktree: teach `list` to annotate locked worktree,
2020-10-11) taught "git worktree list" to annotate locked worktrees by
appending "locked" text to its output, however, this is not listed in
the --porcelain format.

Teach "list --porcelain" to do the same and add a "locked" attribute
followed by its reason, thus making both default and porcelain format
consistent. If the locked reason is not available then only "locked"
is shown.

The output of the "git worktree list --porcelain" becomes like so:

    $ git worktree list --porcelain

In porcelain mode, if the lock reason contains special characters
such as newlines, they are escaped with backslashes and the entire
reason is enclosed in double quotes. For example:

   $ git worktree list --porcelain
   ...
   locked "worktree's path mounted in\nremovable device"
   ...

Furthermore, let's update the documentation to state that some
attributes in the porcelain format might be listed alone or together
with its value depending whether the value is available or not. Thus
documenting the case of the new "locked" attribute.

47409e75f5 t2402: ensure locked worktree is properly cleaned up
c57b3367be (worktree: teach `list` to annotate locked worktree,
2020-10-11) introduced a new test to ensure locked worktrees are listed
with "locked" annotation. However, the test does not clean up after
itself as "git worktree prune" is not going to remove the locked worktree
in the first place. This not only leaves the test in an unclean state it
also potentially breaks following tests that rely on the
"git worktree list" output.

Let's fix that by unlocking the worktree before the "prune" command.

eb36135af7 worktree: teach worktree_lock_reason() to gently handle main worktree
worktree_lock_reason() aborts with an assertion failure when called on
the main worktree since locking the main worktree is nonsensical. Not
only is this behavior undocumented, thus callers might not even be aware
that the call could potentially crash the program, but it also forces
clients to be extra careful:

    if (!is_main_worktree(wt) && worktree_locked_reason(...))
        ...

Since we know that locking makes no sense in the context of the main
worktree, we can simply return false for the main worktree, thus making
client code less complex by eliminating the need for the callers to have
inside knowledge about the implementation:

    if (worktree_lock_reason(...))
        ...

fc0c7d5e9e worktree: teach worktree to lazy-load "prunable" reason
Add worktree_prune_reason() to allow a caller to discover whether a
worktree is prunable and the reason that it is, much like
worktree_lock_reason() indicates whether a worktree is locked and the
reason for the lock. As with worktree_lock_reason(), retrieve the
prunable reason lazily and cache it in the `worktree` structure.

a29a8b7574 worktree: libify should_prune_worktree()
As part of teaching "git worktree list" to annotate worktree that is a
candidate for pruning, let's move should_prune_worktree() from
builtin/worktree.c to worktree.c in order to make part of the worktree
public API.

should_prune_worktree() knows how to select the given worktree for
pruning based on an expiration date, however the expiration value is
stored in a static file-scope variable and it is not local to the
function. In order to move the function, teach should_prune_worktree()
to take the expiration date as an argument and document the new
parameter that is not immediately obvious.

Also, change the function comment to clearly state that the worktree's
path is returned in `wtpath` argument.
