Asciidoc requires lists to start with an empty line and uses
different characters for indentation levels ("-", "*", "**", ...).
For special symbols like a dash "--" has to be used and there is
no double arrow "<->", so a left and right arrow "<-->" has to be
combined for that. Lastly for verbatim output a newline followed
by an indentation has to be used.
Fix asciidoc output for lists, special characters and verbatim
text while retaining the readabilty of the original text file.

Previously, we waited for the child process to be finished in every
failing code path as well as at the end of the function
`show_range_diff()`.
However, we do not need to wait that long. Directly after reading the
output of the child process, we can wrap up the child process.
This also has the advantage that we don't do a bunch of unnecessary work
in case `finish_command()` returns with an error anyway.

In library functions, we do want to avoid the (simple, but rather final)
`die()` calls, instead returning with a value indicating an error.
Let's do exactly that in the code introduced in b66885a30cb8
(range-diff: add section header instead of diff header, 2019-07-11) that
wants to error out if a diff header could not be parsed.

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,
76759c7dff53 "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 90a78b83e0b8 "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 8e712ef6fc97 "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, 76759c7dff53, 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.

When git invokes a pager that exits with non-zero the common case is
that we'll already return the correct SIGPIPE failure from git itself,
but the exit code logged in trace2 has always been incorrectly
reported[1]. Fix that and log the correct exit code in the logs.
Since this gives us something to test outside of our recently-added
tests needing a !MINGW prerequisite, let's refactor the test to run on
MINGW and actually check for SIGPIPE outside of MINGW.
The wait_or_whine() is only called with a true "in_signal" from from
finish_command_in_signal(), which in turn is only used in pager.c.
The "in_signal && !WIFEXITED(status)" case is not covered by
tests. Let's log the default -1 in that case for good measure.
1. The incorrect logging of the exit code in was seemingly copy/pasted
into finish_command_in_signal() in ee4512ed481 (trace2: create new
combined trace facility, 2019-02-22)

Add tests for how git behaves when the pager itself exits with
non-zero, as well as for us exiting with 141 when we're killed with
SIGPIPE due to the pager not consuming its output.
There is some recent discussion[1] about these semantics, but aside
from what we want to do in the future, we should have a test for the
current behavior.
This test construct is stolen from 7559a1be8a0 (unblock and unignore
SIGPIPE, 2014-09-18). The reason not to make the test itself depend on
the MINGW prerequisite is to make a subsequent commit easier to read.

Before checking if the repository has a commit-graph loaded, be sure
to run prepare_commit_graph(). This is necessary because otherwise
the topo_levels slab is not initialized. As we compute topo_levels for
the new commits, we iterate further into the lower layers since the
first visit to each commit looks as though the topo_level is not
populated.
By properly initializing the topo_slab, we fix the previously broken
case of a split commit graph where a base layer has the
generation_data_overflow chunk.

When upgrading to a commit-graph with corrected commit dates from
one without, there are a few things that need to be considered.
When computing generation numbers for the new commit-graph file that
expects to add the generation_data chunk with corrected commit
dates, we need to ensure that the 'generation' member of the
commit_graph_data struct is set to zero for these commits.
Unfortunately, the fallback to use topological level for generation
number when corrected commit dates are not available are causing us
harm here: parsing commits notices that read_generation_data is
false and populates 'generation' with the topological level.
The solution is to iterate through the commits, parse the commits
to populate initial values, then reset the generation values to
zero to trigger recalculation. This loop only occurs when the
existing commit-graph data has no corrected commit dates.
While this improves our situation somewhat, we have not completely
solved the issue for correctly computing generation numbers for mixed
layers. That follows in the next change.

The compute_generation_numbers() method was introduced by 3258c663
(commit-graph: compute generation numbers, 2018-05-01) to compute what
is now known as "topological levels". These are still stored in the
commit-graph file for compatibility sake while c1a09119 (commit-graph:
implement corrected commit date, 2021-01-16) updated the method to also
compute the new version of generation numbers: corrected commit date.
It makes sense why these are grouped. They perform very similar walks of
the necessary commits and compute similar maximums over each parent.
However, having these two together conflates them in subtle ways that is
hard to separate.
In particular, the topo_level slab is used to store the topological
levels in all cases, but the commit_graph_data_at(c)->generation member
stores different values depending on the state of the existing
commit-graph file.
* If the existing commit-graph file has a "GDAT" chunk, then these
values represent corrected commit dates.
* If the existing commit-graph file doesn't have a "GDAT" chunk, then
these values are actually the topological levels.
This issue only occurs only when upgrading an existing commit-graph file
into one that has the "GDAT" chunk. The current change does not resolve
this upgrade problem, but splitting the implementation into two pieces
here helps with that process, which will follow in the next change.
The important thing this helps with is the case where the
num_generation_data_overflows was being incremented incorrectly,
triggering a write of the overflow chunk.

commit dates from any layer of a commit-graph chain if there is a
single commit-graph file that is missing the generation_data chunk.

returns 1 if all layers have a generation_data chunk. This return

There is a subtle failure happening when computing corrected commit
dates with --split enabled. It requires a base layer needing the
generation_data_overflow chunk. Then, the next layer on top
erroneously thinks it needs an overflow chunk due to a bug leading
to recalculating all reachable generation numbers. The output of
the failure is
BUG: commit-graph.c:1912: expected to write 8 bytes to
chunk 47444f56, but wrote 0 instead
These "expected" 8 bytes are due to re-computing the corrected
commit date for the lower layer but the new layer does not need
any overflow.
Add a test to t5318-commit-graph.sh that demonstrates this bug. However,
it does not trigger consistently with the existing code.
The generation number data is stored in a slab and accessed by
commit_graph_data_at(). This data is initialized when parsing a commit,
but is otherwise used assuming it has been populated. The loop in
compute_generation_numbers() did not enforce that all reachable
commits were parsed and had correct values. This could lead to some
problems when writing a commit-graph with corrected commit dates based
on a commit-graph without them.
It has been difficult to identify the issue here because it was so hard
to reproduce. It relies on this uninitialized data having a non-zero
value, but also on specifically in a way that overwrites the existing
data.
This patch adds the extra parse to ensure the data is filled before we
compute the generation number of a commit. This triggers the new test
to fail because the generation number overflow count does not match
between this computation and the write for that chunk.
The actual fix will follow as the next few changes.

"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]

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

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
...
worktree /path/to/locked
HEAD 123abcdea123abcd123acbd123acbda123abcd12
detached
locked
worktree /path/to/locked-with-reason
HEAD abc123abc123abc123abc123abc123abc123abc1
detached
locked reason why it is locked
...
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.

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.

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(...))
...

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.

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.

If the commit subject starts with "amend!" then rearrange it like a
"fixup!" commit and replace `pick` command with `fixup -C` command,
which is used to fixup up the content if any and replaces the original
commit message with amend! commit's message.
