Currently, (restore, checkout, reset) commands correctly take '@' as a
synonym for 'HEAD'. However, in patch mode different prompts/messages
are given on command line due to patch mode machinery not considering
'@' to be a synonym for 'HEAD' due to literal string comparison with
the word 'HEAD', and therefore assigning patch_mode_($command)_nothead
and triggering reverse mode (-R in diff-index). The NEEDSWORK comment
suggested comparing commit objects to get around this. However, doing
so would also take a non-checked out branch pointing to the same commit
as HEAD, as HEAD. This would cause confusion to the user.
Therefore, after parsing '@', replace it with 'HEAD' as reasonably
early as possible. This also solves another problem of disparity
between 'git checkout HEAD' and 'git checkout @' (latter detaches at
the HEAD commit and the former does not).
Trade-offs:
- Some of the errors would show the revision argument as 'HEAD' when
given '@'. This should be fine, as most users who probably use '@'
would be aware that it is a shortcut for 'HEAD' and most probably
used to use 'HEAD'. There is also relevant documentation in
'gitrevisions' manpage about '@' being the shortcut for 'HEAD'. Also,
the simplicity of the solution far outweighs this cost.
- Consider '@' as a shortcut for 'HEAD' even if 'refs/heads/@' exists
at a different commit. Naming a branch '@' is an obvious foot-gun and
many existing commands already take '@' for 'HEAD' even if
'refs/heads/@' exists at a different commit or does not exist at all
(e.g. 'git log @', 'git push origin @' etc.). Therefore this is an
existing assumption and should not be a problem.

Sometimes, especially during tests of low level machinery, it is
handy to have a way to disable lazy fetching of objects. This
allows us to say, for example, "git cat-file -e <object-name>", to
see if the object is locally available.

When GIT_FLUSH is set to 1, true, on, yes, then we should disable
skip_stdout_flush, but the conversion somehow did the opposite.
With the understanding of the original motivation behind "skip" in
06f59e9f (Don't fflush(stdout) when it's not helpful, 2007-06-29),
we can sympathize with the current naming (we wanted to avoid
useless flushing of stdout by default, with an escape hatch to
always flush), but it is still not a good excuse.
Retire the "skip_stdout_flush" variable and replace it with "flush_stdout"
that tells if we do or do not want to run fflush().

In a previous commit we removed some hardcoded config variable names from
function __git_complete_config_variable_name in the completion script by
introducing a new function,
__git_compute_first_level_config_vars_for_section.
The remaining hardcoded config variables are "second level"
configuration variables, meaning 'branch.<name>.upstream',
'remote.<name>.url', etc. where <name> is a user-defined name.
Making use of the new existing --config flag to 'git help', add a new
function, __git_compute_second_level_config_vars_for_section. This
function takes as argument a config section name and computes the
corresponding second-level config variables, i.e. those that contain a
'<' which indicates the start of a placeholder. Note that as in
__git_compute_first_level_config_vars_for_section added previsouly, we
use indirect expansion instead of associative arrays to stay compatible
with Bash 3 on which macOS is stuck for licensing reasons.
As explained in the previous commit, we use the existing pattern in the
completion script of using global variables to cache the list of
variables for each section.
Use this new function and the variables it defines in
__git_complete_config_variable_name to remove hardcoded config
variables, and add a test to verify the new function. Use a single
'case' for all sections with second-level variables names, since the
code for each of them is now exactly the same.
Adjust the name of a test added in a previous commit to reflect that it
now tests the added function.

The function __git_complete_config_variable_name in the Bash completion
script hardcodes several config variable names. These variables are
those in config sections where user-defined names can appear, such as
"branch.<name>". These sections are treated first by the case statement,
and the two last "catch all" cases are used for other sections, making
use of the __git_compute_config_vars and __git_compute_config_sections
function, which omit listing any variables containing wildcards or
placeholders. Having hardcoded config variables introduces the risk of
the completion code becoming out of sync with the actual config
variables accepted by Git.
To avoid these hardcoded config variables, introduce a new function,
__git_compute_first_level_config_vars_for_section, making use of the
existing __git_config_vars variable. This function takes as argument a
config section name and computes the matching "first level" config
variables for that section, i.e. those _not_ containing any placeholder,
like 'branch.autoSetupMerge, 'remote.pushDefault', etc. Use this
function and the variables it defines in the 'branch.*', 'remote.*' and
'submodule.*' switches of the case statement instead of hardcoding the
corresponding config variables. Note that we use indirect expansion to
create a variable for each section, instead of using a single
associative array indexed by section names, because associative arrays
are not supported in Bash 3, on which macOS is stuck for licensing
reasons.
Use the existing pattern in the completion script of using global
variables to cache the list of config variables for each section. The
rationale for such caching is explained in eaa4e6ee2a (Speed up bash
completion loading, 2009-11-17), and the current approach to using and
defining them via 'test -n' is explained in cf0ff02a38 (completion: work
around zsh option propagation bug, 2012-02-02).
Adjust the name of one of the tests added in the previous commit,
reflecting that it now also tests the new function.

In the Bash completion script, function
__git_complete_config_variable_name completes config variables and has
special logic to deal with config variables involving user-defined
names, like branch.<name>.* and remote.<name>.*.
This special logic is missing for submodule-related config variables.
Add the appropriate branches to the case statement, making use of the
in-tree '.gitmodules' to list relevant submodules.
Add corresponding tests in t9902-completion.sh, making sure we complete
both first level submodule config variables as well as second level
variables involving submodule names.

In be6444d1ca (completion: bash: add correct suffix in variables,
2021-08-16), __git_complete_config_variable_name was changed to use
"${sfx- }" instead of "$sfx" as the fourth argument of _gitcomp_nl and
_gitcomp_nl_append, such that this argument evaluates to a space if sfx
is unset. This was to ensure that e.g.
git config branch.autoSetupMe[TAB]
correctly completes to 'branch.autoSetupMerge ' with the trailing space.
This commits notes that the fix only works in Bash 4 because in Bash 3
the 'local sfx' construct at the beginning of
__git_complete_config_variable_name creates an empty string.
Make the fix also work for Bash 3 by using the "unset or null' parameter
expansion syntax ("${sfx:- }"), such that the parameter is also expanded
to a space if it is set but null, as is the behaviour of 'local sfx' in
Bash 3.

Add and apply a semantic patch for calling xstrncmpz() to compare a
NUL-terminated string with a buffer of a known length instead of using
strncmp() and checking the terminating NUL explicitly. This simplifies
callers by reducing code duplication.
