If we encounter an error in parse_filter_object_config(), we'll complain
to stderr but won't actually propagate the return value up the stack.
This is unlike most of our config callbacks, which return the error to
git_config() so it can die (this includes the call just below us to
parse_hide_refs_config(), which can also produce errors).

core.sharedRepository defines which permissions Git should set when
creating files in $GIT_DIR, so that the repository may be shared with
other users. But (in its current form) the setting shouldn't affect how
files are created in the working tree. This is not respected by apply
and am (which uses apply), when creating leading directories:
$ cat d.patch
diff --git a/d/f b/d/f
new file mode 100644
index 0000000..e69de29
Apply without the setting:
$ umask 0077
$ git apply d.patch
$ ls -ld d
drwx------
Apply with the setting:
$ umask 0077
$ git -c core.sharedRepository=0770 apply d.patch
$ ls -ld d
drwxrws---
Only the leading directories are affected. That's because they are
created with safe_create_leading_directories(), which calls
adjust_shared_perm() to set the directories' permissions based on
core.sharedRepository. To fix that, let's introduce a variant of this
function that ignores the setting, and use it in apply. Also add a
regression test and a note in the function documentation about the use
of each variant according to the destination (working tree or git
dir).

A test marked with EXPENSIVE creates two 2.5GB files and adds them to
the repository. This takes 194s to run on my machine, versus 2s when the
EXPENSIVE prereq isn't set. We can trim this down a bit by doing two
things:
- use "git commit --quiet" to avoid spending time generating a diff
summary (this actually only helps for the second commit, but I've
added it here to both for consistency). This shaves off 8s.
- set core.compression to 0. We know these files are full of random
bytes, and so won't compress (that's the point of the test!).
Spending cycles on zlib is pointless. This shaves off 122s.
After this, my total time to run the script is 64s. That won't help
normal runs without GIT_TEST_LONG set, of course, but it's easy enough
to do.

Since commit 9ba89f484e git learned how to push to a remote branch using
the source @, for example:
git push origin @:master
However, if the right-hand side is missing, the push fails:
git push origin @
It is obvious what is the desired behavior, and allowing the push makes
things more consistent.
Additionally, @:master now has the same semantics as HEAD:master.

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.

When a repository's leading directories contain regex metacharacters,
the config calls for 'git maintenance register' and 'git maintenance
unregister' are not careful enough. Use the new --fixed-value option
to direct the config machinery to use exact string matches. This is a
more robust option than escaping these arguments in a piecemeal fashion.
For the test, require that we are not running on Windows since the '+'
and '*' characters are not allowed on that filesystem.

The config builtin does its own regex matching of values for the --get,
--get-all, and --get-regexp modes. Plumb the existing 'flags' parameter
to the get_value() method so we can initialize the value-pattern argument

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.

The 'git config' builtin takes a 'value-pattern' parameter for several
actions. This can cause confusion when expecting exact value matches
instead of regex matches, especially when the input string contains
metacharacters. While callers can escape the patterns themselves, it
would be more friendly to allow an argument to disable the pattern
matching in favor of an exact string match.
Add a new '--fixed-value' option that does not currently change the
behavior. The implementation will be filled in by later changes for
each appropriate action. For now, check and test that --fixed-value
will abort the command when included with an incompatible action or
without a 'value-pattern' argument.
The name '--fixed-value' was chosen over something simpler like
'--fixed' because some commands allow regular expressions on the
key in addition to the value.

Without additional modifiers, 'git config <key> <value>' attempts
to set a single value in the .git/config file. When the
value-pattern parameter is supplied, this command behaves in a
non-trivial manner.
Consider 'git config <key> <value> <value-pattern>'. The expected
behavior is as follows:
1. If there are multiple existing values that match 'value-pattern',
then the command fails. Users should use --replace-all instead.
2. If there is no existing values match 'value-pattern', then the
'key=value' pair is appended, making this 'key' a multi-valued
config setting.
3. If there is one existing value that matches 'value-pattern', then
the new config has one entry where 'key=value'.
Add a test that demonstrates these options. Break from the existing
pattern in t1300-config.sh to use 'git config --file=<file>' instead of
modifying .git/config directly to prevent possibly incompatible repo
states. Also use 'git config --file=<file> --list' for config state
comparison instead of the config file format. This makes the tests
more readable.

When a packed object is stored in a multi-pack index, but that pack has
racily gone away, the MIDX code simply calls die(), when it could be
returning an error to the caller, which would in turn lead to
re-scanning the pack directory.
A pack can racily disappear, for example, due to a simultaneous 'git
repack -ad',
You can also reproduce this with two terminals, where one is running:
git init
while true; do
git commit -q --allow-empty -m foo
git repack -ad
git multi-pack-index write
done
(in effect, constantly writing new MIDXs), and the other is running:
obj=$(git rev-parse HEAD)
while true; do
echo $obj | git cat-file --batch-check='%(objectsize:disk)' || break
done
That will sometimes hit the error preparing packfile from
multi-pack-index message, which this patch fixes.
Right now, that path to discovering a missing pack looks something like
'find_pack_entry()' calling 'fill_midx_entry()' and eventually making
its way to call 'nth_midxed_pack_entry()'.
'nth_midxed_pack_entry()' already checks 'is_pack_valid()' and
propagates an error if the pack is invalid. So, this works if the pack
has gone away between calling 'prepare_midx_pack()' and before calling
'is_pack_valid()', but not if it disappears before then.
Catch the case where the pack has already disappeared before
'prepare_midx_pack()' by returning an error in that case, too.

In 17c35c8969 (packfile: skip loading index if in multi-pack-index,
2018-07-12) we stopped loading the .idx file for packs that are
contained within a multi-pack index.
This saves us the effort of loading an .idx and doing some lightweight
validity checks by way of 'packfile.c:load_idx()', but introduces a race
between processes that need to load the index (e.g., to generate a
reverse index) and processes that can delete the index.
For example, running the following in your shell:
$ git init repo && cd repo
$ git commit --allow-empty -m 'base'
$ git repack -ad && git multi-pack-index write
followed by:
$ rm -f .git/objects/pack/pack-*.idx
$ git rev-parse HEAD | git cat-file --batch-check='%(objectsize:disk)'
will result in a segfault prior to this patch. What's happening here is
that we notice that the pack is in the multi-pack index, and so don't
check that it still has a .idx. When we then try and load that index to
generate a reverse index, we don't have it, so the call to
'find_pack_revindex()' in 'packfile.c:packed_object_info()' returns
NULL, and then dereferencing it causes a segfault.
Of course, we don't ever expect someone to remove the index file by
hand, or to be in a state where we never wrote it to begin with (yet
find that pack in the multi-pack-index). But, this can happen in a
timing race with 'git repack -ad', which removes all existing packs
after writing a new pack containing all of their objects.
Avoid this by reverting the hunk of 17c35c8969 which stops loading the
index when the pack is contained in a MIDX. This makes the latter half
of 17c35c8969 useless, since we'll always have a non-NULL
'p->index_data', in which case that if statement isn't guarding
anything.
These two together effectively revert 17c35c8969, and avoid the race
explained above.

While help.autocorrect can be set to 0 to decline auto-execution of

Update help.autocorrect to accept the string "never" to just exit

see suggested corrections at all.
While at it, introduce "immediate" as a more readable way to
immediately execute the auto-corrected command, which can be done
