'git for-each-repo --config=X' should return success without calling any
subcommands when the config key 'X' has no value. The current
implementation instead segfaults.
A user could run into this issue if they used 'git maintenance start' to
initialize their cron schedule using 'git for-each-repo
--config=maintenance.repo ...' but then using 'git maintenance
unregister' to remove the config option. (Note: 'git maintenance stop'
would remove the config _and_ remove the cron schedule.)
Add a simple test to ensure this works. Use 'git help --no-such-option'
as the potential subcommand to ensure that we will hit a failure if the
subcommand is ever run.

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
28438e84e04 (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 d4919bb288e (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.

Change the reverse/ignore_case/version sort flags in the ref_sorting
struct into a bitfield. Having three of them was already a bit
unwieldy, but it would be even more so if another flag needed a
function like ref_sorting_icase_all() introduced in
76f9e569adb (ref-filter: apply --ignore-case to all sorting keys,
2020-05-03).
A follow-up change will introduce such a flag, so let's move this over
to a bitfield. Instead of using the usual '#define' pattern I'm using
the "enum" pattern from builtin/rebase.c's b4c8eb024af (builtin
rebase: support --quiet, 2018-09-04).
Perhaps there's a more idiomatic way of doing the "for each in list
amend mask" pattern than this "mask/on" variable combo. This function
doesn't allow us to e.g. do any arbitrary changes to the bitfield for
multiple flags, but I think in this case that's fine. The common case
is that we're calling this with a list of one.

On `git maintenance start`, we add a few entries to the user's cron
table. We wrap our entries using two magic markers, "# BEGIN GIT
MAINTENANCE SCHEDULE" and "# END GIT MAINTENANCE SCHEDULE". At a later
`git maintenance stop`, we will go through the table and remove these
lines. Or rather, we will remove the "BEGIN" marker, the "END" marker
and everything between them.
Alas, we have a bug in how we detect the "END" marker: we don't. As we
loop through all the lines of the crontab, if we are in the "old
region", i.e., the region we're aiming to remove, we make an early
`continue` and don't get as far as checking for the "END" marker. Thus,
once we've seen our "BEGIN", we remove everything until the end of the
file.
Rewrite the logic for identifying these markers. There are four cases
that are mutually exclusive: The current line starts a region or it ends
it, or it's firmly within the region, or it's outside of it (and should
be printed).

Remove this unreachable code. It was found by SunCC, it's found by a
non-fatal warning emitted by SunCC. It's one of the things it's more
vehement about than GCC & Clang.
It complains about a lot of other similarly unreachable code, e.g. a
BUG(...) without a "return", and a "return 0" after a long if/else,
both of whom have "return" statements. Those are also genuine
redundancies to a compiler, but arguably make the code a bit easier to
read & less fragile to maintain.
These return/break cases are just unnecessary however, and as seen
here the surrounding code just did a plain "return" without a "break"
already.

We are about to introduce a message giving users running `git init` some
advice about `init.defaultBranch`. This will necessarily be done in
`repo_default_branch_name()`.
Not all code paths want to show that advice, though. In particular, the
`git clone` codepath _specifically_ asks for `init_db()` to be quiet,
via the `INIT_DB_QUIET` flag.
In preparation for showing users above-mentioned advice, let's change
the function signature of `get_default_branch_name()` to accept the
parameter `quiet`.

If 'git clone' couldn't execute 'transport_fetch_refs()' (e.g., because
of an error on the remote's side in 'git upload-pack'), then it will
silently ignore it.
Even though this has been the case at least since clone was ported to C
(way back in 8434c2f1af (Build in clone, 2008-04-27)), 'git fetch'
doesn't ignore these and reports any failures it sees.
That suggests that ignoring the return value in 'git clone' is simply an
oversight that should be corrected. That's exactly what this patch does.
(Noticing and fixing this is no coincidence, we'll want it in the next
patch in order to demonstrate a regression in 'git upload-pack' via a
'git clone'.)
There's no additional logging here, but that matches how 'git fetch'
handles the same case. An assumption there is that whichever part of
transport_fetch_refs() fails will complain loudly, so any additional
logging here is redundant.

sparse-checkouts are built on the patterns in the
$GIT_DIR/info/sparse-checkout file, where commands have modified
behavior for paths that do not match those patterns. The differences in
behavior, as far as the bugs concerned here, fall into three different
categories (with git subcommands that fall into each category listed):
* commands that only look at files matching the patterns:
* status
* diff
* clean
* update-index
* commands that remove files from the working tree that do not match
the patterns, and restore files that do match them:
* read-tree
* switch
* checkout
* reset (--hard)
* commands that omit writing files to the working tree that do not
match the patterns, unless those files are not clean:
* merge
* rebase
* cherry-pick
* revert
There are some caveats above, e.g. a plain `git diff` ignores files
outside the sparsity patterns but will show diffs for paths outside the
sparsity patterns when revision arguments are passed. (Technically,
diff is treating the sparse paths as matching HEAD.) So, there is some
internal inconsistency among these commands. There are also additional
commands that should behave differently in the face of sparse-checkouts,
as the sparse-checkout documentation alludes to, but the above is
sufficient for me to explain how `git stash` is affected.
What is relevant here is that logically 'stash' should behave like a
merge; it three-way merges the changes the user had in progress at stash
creation time, the HEAD at the time the stash was created, and the
current HEAD, in order to get the stashed changes applied to the current
branch. However, this simplistic view doesn't quite work in practice,
because stash tweaks it a bit due to two factors: (1) flags like
--keep-index and --include-untracked (why we used two different verbs,
'keep' and 'include', is a rant for another day) modify what should be
staged at the end and include more things that should be quasi-merged,
(2) stash generally wants changes to NOT be staged. It only provides
exceptions when (a) some of the changes had conflicts and thus we want
to use stages to denote the clean merges and higher order stages to
mark the conflicts, or (b) if there is a brand new file we don't want
it to become untracked.
stash has traditionally gotten this special behavior by first doing a
merge, and then when it's clean, applying a pipeline of commands to
modify the result. This series of commands for
unstaging-non-newly-added-files came from the following commands:
git diff-index --cached --name-only --diff-filter=A $CTREE >"$a"
git read-tree --reset $CTREE
git update-index --add --stdin <"$a"
rm -f "$a"
Looking back at the different types of special sparsity handling listed
at the beginning of this message, you may note that we have at least one
of each type covered here: merge, diff-index, and read-tree. The weird
mix-and-match led to 3 different bugs:
(1) If a path merged cleanly and it didn't match the sparsity patterns,
the merge backend would know to avoid writing it to the working tree and
keep the SKIP_WORKTREE bit, simply only updating it in the index.
Unfortunately, the subsequent commands would essentially undo the
changes in the index and thus simply toss the changes altogether since
there was nothing left in the working tree. This means the stash is
only partially applied.
(2) If a path existed in the worktree before `git stash apply` despite
having the SKIP_WORKTREE bit set, then the `git read-tree --reset` would
print an error message of the form
error: Entry 'modified' not uptodate. Cannot merge.
and cause stash to abort early.
(3) If there was a brand new file added by the stash, then the
diff-index command would save that pathname to the temporary file, the
read-tree --reset would remove it from the index, and the update-index
command would barf due to no such file being present in the working
copy; it would print a message of the form:
error: NEWFILE: does not exist and --remove not passed
fatal: Unable to process path NEWFILE
and then cause stash to abort early.
Basically, the whole idea of unstage-unless-brand-new requires special
care when you are dealing with a sparse-checkout. Fix these problems
by applying the following simple rule:
When we unstage files, if they have the SKIP_WORKTREE bit set,
clear that bit and write the file out to the working directory.
(*) If there's already a file present in the way, rename it first.
This fixes all three problems in t7012.13 and allows us to mark it as
passing.

When stash was converted from shell to a builtin, it merely
transliterated the forking of various git commands from shell to a C
program that would fork the same commands. Some of those were converted
over to actual library calls, but much of the pipeline-of-commands
design still remains. Fix some of this by replacing the portion
corresponding to
git diff-index --cached --name-only --diff-filter=A $CTREE >"$a"
git read-tree --reset $CTREE
git update-index --add --stdin <"$a"
rm -f "$a"
into a library function that does the same thing. (The read-tree
--reset was already partially converted over to a library call, but as
an independent piece.) Note here that this came after a merge operation
was performed. The merge machinery always stages anything that cleanly
merges, and the above code only runs if there are no conflicts. Its
purpose is to make it so that when there are no conflicts, all the
changes from the stash are unstaged. However, that causes brand new
files from the stash to become untracked, so the code above first saves
those files off and then re-adds them afterwards.
We replace the whole series of commands with a simple function that will
unstage files that are not newly added. This doesn't fix any bugs in
the usage of these commands, it simply matches the existing behavior but
makes it into a single atomic operation that we can then operate on as a
whole. A subsequent commit will take advantage of this to fix issues
with these commands in sparse-checkouts.
This conversion incidentally fixes t3906.1, because the separate
update-index process would die with the following error messages:
error: uninitialized_sub: is a directory - add files inside instead
fatal: Unable to process path uninitialized_sub
The unstaging of the directory as a submodule meant it was no longer
tracked, and thus as an uninitialized directory it could not be added
back using `git update-index --add`, thus resulting in this error and
early abort. Most of the submodule tests in 3906 continue to fail after
this change, this change was just enough to push the first of those
tests to success.

To generate its filename, the 'git bugreport' builtin asks the system
for the current time with 'localtime()'. Since this uses a shared
buffer, it is not thread-safe.
Even though 'git bugreport' is not multi-threaded, using localtime() can
trigger some static analysis tools to complain, and a quick
$ git grep -oh 'localtime\(_.\)\?' -- **/*.c | sort | uniq -c
shows that the only usage of the thread-unsafe 'localtime' is in a piece
of documentation.
So, convert this instance to use the thread-safe version for
consistency, and to appease some analysis tools.

The "git maintenance run" and "git maintenance start/stop" commands
holds a file-based lock at the .git/maintenance.lock and
.git/schedule.lock respectively. These locks are used to ensure only
one maintenance process is executed at the time as both operations
involves writing data into the git repository.
The path to the lock file is built using
"the_repository->objects->odb->path" that results in SEGFAULT when we
have no repository available as "the_repository->objects->odb" is
set to NULL.
Let's teach maintenance command to use RUN_SETUP option that will
provide the validation and fail when running outside of a repository.
Hence fixing the SEGFAULT for all three operations and making the
behaviour consistent across all subcommands.
Setting the RUN_SETUP also provides the same protection for all
subcommands given that the "register" and "unregister" also requires to
be executed inside a repository.
Furthermore let's remove the local validation implemented by the
"register" and "unregister" as this will not be required anymore with
the new option.

The git_config_set_multivar_in_file_gently() and related methods now
take a 'flags' bitfield, so add a new bit representing the --fixed-value
option from 'git config'. This alters the purpose of the value_pattern
parameter to be an exact string match. This requires some initialization
changes in git_config_set_multivar_in_file_gently() and a new strcmp()
call in the matches() method.
The new CONFIG_FLAGS_FIXED_VALUE flag is initialized in builtin/config.c
based on the --fixed-value option, and that needs to be updated in
several callers.
This patch only affects some of the modes of 'git config', and the rest
will be completed in the next change.
