At times, we may need to push the same commit to multiple branches
in the same push. Rewinding 'next' to rebuild on top of 'master'
soon after a release is such an occasion. Making sure 'main' stays
in sync with 'master' to help those who expect that primary branch
of the project is named either of these is another.
We already use the branch name as a "concurrency group" key, but
that does not address the situation illustrated above.
Let's introduce another `concurrency` attribute, using the commit
hash as the concurrency group key, on the workflow run level, to
address this. This will hold any workflow run in the queued state
when there is already a workflow run targeting the same commit,
until that latter run completed. The `skip-if-redundant` check of
the second run will then have a chance to see whether the first
run succeeded.
The only caveat with this strategy is that only one workflow run
will be kept in the queued state by the `concurrency` feature: if
another run targeting the same commit is triggered, the
previously-queued run will be canceled. Considering the benefit,
this seems the smaller price to pay than to overload Git's build
agent pool with undesired workflow runs.

git-gui enables the "Repository->Create Desktop Icon" item on Cygwin,
offering to create a shortcut that starts git-gui on the current
repository. The code in do_cygwin_shortcut invokes function
win32_create_lnk to create the shortcut. This latter function is shared
between Cygwin and Git For Windows and expects Windows rather than unix
pathnames, though do_cygwin_shortcut provides unix pathnames. Also, this
function tries to invoke the Windows Script Host to run a javascript
snippet, but this fails under Cygwin's Tcl. So, win32_create_lnk just
does not support Cygwin.
However, Cygwin's default installation provides /bin/mkshortcut for
creating desktop shortcuts. This is compatible with exec under Cygwin's
Tcl, understands Cygwin's unix pathnames, and avoids the need for shell
escapes to encode troublesome paths. So, teach git-gui to use mkshortcut
on Cygwin, leaving win32_create_lnk unchanged and for exclusive use by
Git For Windows.
Notes: "CHERE_INVOKING=1" is recognized by Cygwin's /etc/profile and
prevents a "chdir $HOME", leaving the shell in the working directory
specified by the shortcut. That directory is written directly by
mkshortcut eliminating any problems with shell escapes and quoting.
The code being replaced includes the full pathname of the git-gui
creating the shortcut, but that git-gui might not be compatible with the
git found after /etc/profile sets the path, and might have a pathname
that defies encoding using shell escapes that can survive the multiple
incompatible interpreters involved in the chain of creating and using
this shortcut. The new code uses bare "git gui" as the command to
execute, thus using the system git to launch the system git-gui, and
avoiding both issues.

git-gui enables the "Repository->Explore Working Copy" menu on Cygwin,
offering to open a Windows graphical file browser at the root of the
working directory. This code, shared with Git For Windows support,
depends upon use of Windows pathnames. However, git gui on Cygwin uses
unix pathnames, so this shared code will not work on Cygwin.
A base install of Cygwin provides the /bin/cygstart utility that runs
a registered Windows application based upon the file type, after
translating unix pathnames to Windows. Adding the --explore option
guarantees that the Windows file explorer is opened, regardless of the
supplied pathname's file type and avoiding possibility of some other
action being taken.
So, teach git-gui to use cygstart --explore on Cygwin, restoring the
pre-2012 behavior of opening a Windows file explorer for browsing. This
separates the Git For Windows and Cygwin code paths. Note that
is_Windows is never true on Cygwin, and is_Cygwin is never true on Git
for Windows, though this is not obvious by examining the code for those

In the current git release, git-gui runs on Cygwin without enabling any
of git-gui's Cygwin specific code. This happens as the Cygwin specific
code in git-gui was (mostly) written in 2007-2008 to work with Cygwin's
then supplied Tcl/Tk which was an incompletely ported variant of the
8.4.1 Windows Tcl/Tk code. In March, 2012, that 8.4.1 package was
replaced with a full port based upon the upstream unix/X11 code,
since maintained up to date. The two Tcl/Tk packages are completely
incompatible, and have different signatures.
When Cygwin's Tcl/Tk signature changed in 2012, git-gui no longer
detected Cygwin, so did not enable Cygwin specific code, and the POSIX
environment provided by Cygwin since 2012 supported git-gui as a generic
unix. Thus, no-one apparently noticed the existence of incompatible
Cygwin specific code.
However, since commit c5766eae6f in the git-gui source tree
(https://github.com/prati0100/git-gui, master at a5005ded), and not yet
pulled into the git repository, the is_Cygwin function does detect
Cygwin using the unix/X11 Tcl/Tk. The Cygwin specific code is enabled,
causing use of Windows rather than unix pathnames, and enabling
incorrect warnings about environment variables that were relevant only
to the old Tcl/Tk. The end result is that (upstream) git-gui is now
incompatible with Cygwin.
So, delete Cygwin specific code (code protected by "if is_Cygwin") that
is not needed in any form to work with the unix/X11 Tcl/Tk.
Cygwin specific code required to enable file browsing and shortcut
creation is not addressed in this patch, does not currently work, and
invocation of those items may leave git-gui in a confused state.

git-gui's Makefile hardcodes the absolute Windows path of git-gui's libraries
into git-gui, destroying the ability to package git-gui on one machine and
distribute to others. The intent is to do this only if a non-Cygwin Tcl/Tk is
installed, but the test for this is wrong with the unix/X11 Tcl/Tk shipped
since 2012. Also, Cygwin does not support a non-Cygwin Tcl/Tk.
The Cygwin git maintainer disables this code, so this code is definitely
not in use in the Cygwin distribution.
The simplest fix is to just delete the Cygwin specific code,
allowing the Makefile to work out of the box on Cygwin. Do so.

In verify_one_commit_graph(), we have code that complains when a commit
is found with a generation number of zero, and then later with a
non-zero number. It works like this:
1. When we see an entry with generation zero, we set the
generation_zero flag to GENERATION_ZERO_EXISTS.
2. When we later see an entry with a non-zero generation, we complain
if the flag is GENERATION_ZERO_EXISTS.
There's a matching GENERATION_NUMBER_EXISTS value, which in theory would
be used to find the case that we see the entries in the opposite order:
1. When we see an entry with a non-zero generation, we set the
generation_zero flag to GENERATION_NUMBER_EXISTS.
2. When we later see an entry with a zero generation, we complain if
the flag is GENERATION_NUMBER_EXISTS.
But that doesn't work; step 2 is implemented, but there is no step 1. We
never use NUMBER_EXISTS at all, and Coverity rightly complains that step
2 is dead code.

In 2ee11f7261 (commit-graph: return generation from memory, 2023-03-20),
the `commit_graph_generation()` function stopped returning zeros when
asked to locate the generation number of a given commit.
This was done at the time to prepare for a later change which set
generation values in memory, meaning that we could no longer rely on
`graph_pos` alone to tell us whether or not to trust the generation
number returned by this function.
In 2ee11f7261, it was noted that this change only impacted very old
commit-graphs, which were written with all commits having generation
number 0. Indeed, zero is not a valid generation number, so we should
never expect to see that value outside of the aforementioned case.
The test fallout in 2ee11f7261 indicated that we were no longer able to
fsck a specific old case of commit-graph corruption, where we see a
non-zero generation number after having seen a generation number of 0
earlier.
Introduce a variant of `commit_graph_generation()` which behaves like
that function did prior to 2ee11f7261, known as
`commit_graph_generation_from_graph()`. Then use this function in the
context of `verify_one_commit_graph()`, where we only want to trust the

Many programs use diff_result_code() to get a user-visible program exit
code from a diff result (e.g., checking opts.found_changes if
--exit-code was requested).
This function also takes a "status" parameter, which seems at first
glance that it could be used to propagate an error encountered when
computing the diff. But it doesn't work that way:
- negative values are passed through as-is, but are not appropriate as
program exit codes
- when --exit-code or --check is in effect, we _ignore_ the passed-in
status completely. So a failed diff which did not have a chance to
set opts.found_changes would erroneously report "success, no
changes" instead of propagating the error.
After recent cleanups, neither of these bugs is possible to trigger, as
every caller just passes in "0". So rather than fixing them, we can
simply drop the useless parameter instead.

Since git-diff has many diff modes, it dispatches to many helpers to
perform each one. But every helper simply returns "0", as it exits
directly if there are serious errors (and options like --exit-code are
handled afterwards). So let's get rid of these useless return values,
which makes the code flow more clear.
There's very little chance that we'd later want to propagate errors
instead of dying immediately. These are all static-local helpers for the
git-diff program implementing its various modes. More "lib-ified" code
would directly call the underlying functions.

Neither of these functions ever returns a value other than zero.
Instead, they expect unrecoverable errors to exit immediately, and
things like "--exit-code" are stored inside the diff_options struct to
be handled later via diff_result_code().
Some callers do check the return values, but many don't bother. Let's
drop the useless return values, which are misleading callers about how
the functions work. This could be seen as a step in the wrong direction,
as we might want to eventually "lib-ify" these to more cleanly return
errors up the stack, in which case we'd have to add the return values
back in. But there are some benefits to doing this now:
1. In the current code, somebody could accidentally add a "return -1"
to one of the functions, which would be erroneously ignored by many
callers. By removing the return code, the compiler can notice the
mismatch and force the developer to decide what to do.
Obviously the other option here is that we could start consistently
checking the error code in every caller. But it would be dead code,
and we wouldn't get any compile-time help in catching new cases.
2. It communicates the situation to callers, who may want to choose a
different function. These functions are really thin wrappers for
doing git-diff-files and git-diff-index within the process. But
callers who care about recovering from an error here are probably
better off using the underlying library functions, many of
which do return errors.
If somebody eventually wants to teach these functions to propagate
errors, they'll have to switch back to returning a value, effectively
reverting this patch. But at least then they will be starting with a
level playing field: they know that they will need to inspect each
caller to see how it should handle the error.

When the git-diff program fails to read the index in its diff-files or
diff-index helper functions, it propagates the error up the stack. This
eventually lands in diff_result_code(), which does not handle it well
(as discussed in the previous patch).
Since the only sensible thing here is to exit with an error code (and
what we were expecting the propagated error code to cause), let's just
do that directly.
There's no test here, as I'm not even sure this case can be triggered.
The index-reading functions tend to die() themselves when encountering
any errors, and the return value is just the number of entries in the
file (and so always 0 or positive). But let's err on the conservative
side and keep checking the return value. It may be worth digging into as
a separate topic (though index-reading is low-level enough that we
probably want to eventually teach it to propagate errors anyway for
lib-ification purposes, at which point this code would already be doing
the right thing).

The git-diff command has many modes (comparing worktree to index, index
to HEAD, individual blobs, etc). As a result, it dispatches to many
helper functions and cannot completely parse its options until we're in
those helper functions.
Most of them, when seeing an unknown option, exit immediately by calling
usage(). But builtin_diff_files(), which is the default if no revision
or blob arguments are given, instead prints an error() and returns -1.
One obvious shortcoming here is that the user doesn't get to see the
usual usage message. But there's a much more important bug: the -1
return is fed to diff_result_code(), which is not ready to handle it.
By default, it passes the code along as an exit code. We try to avoid
negative exit codes because they get converted to unsigned values, but
it should at least consistently show up as non-zero (i.e., a failure).
But much worse is that when --exit-code is in effect, diff_result_code()
will _ignore_ the status passed in by the caller, and instead only
report on whether the diff found changes. It didn't, of course, because
we never ran the diff, and the program unexpectedly exits with success!
We can fix this bug by just calling usage(), like the other helpers do.
Another option would of course be to teach diff_result_code() to handle
this value. But as we'll see in the next few patches, it can be cleaned
up even further. Let's just fix this bug directly to start with.

If loading the index fails, we print an error and then return "-1" from
the function. But since this is a builtin, we end up with exit(-1),
which produces odd results since program exit codes are unsigned.
Because of integer conversion, it usually becomes 255, which is at least
still an error, but values above 128 are usually interpreted as signal
death.
Since we know the program is exiting immediately, we can just replace
the error return with a die().

Many callers of run_diff_index() passed literal "1" for the option

The other bit in the option flag word is DIFF_INDEX_MERGE_BASE, but

A bit tricky call to the function is in builtin/submodule--helper.c
