The idea of the magic value "ac4f2ee" in this test is to make the
reworded commit `collide2` have the same shortened ID as the commit
`collide3`.
To port the same idea to the SHA-256 version of Git, we therefore need
another magic value that causes the same collision, but this time with
the SHA-256 version of the commit IDs.
In this patch, we add code guarded by `GIT_TEST_FIND_COLLIDER` to do
exactly that. Essentially, a large number of integers is appended to the
commit message "collide2" to find such a collision. To make it easier to
find such a collision, we reduce the number of digits to 4.
As the tests are no longer dependent on SHA-1, we also rename their
titles to talk about "commit IDs" instead of "SHA-1s".

Code which split an argv_array call across multiple lines, like:
argv_array_pushl(&args, "one argument",
"another argument", "and more",
NULL);
was recently mechanically renamed to use strvec, which results in
mis-matched indentation like:
strvec_pushl(&args, "one argument",
"another argument", "and more",
NULL);
Let's fix these up to align the arguments with the opening paren. I did
this manually by sifting through the results of:
git jump grep 'strvec_.*,$'
and liberally applying my editor's auto-format. Most of the changes are
of the form shown above, though I also normalized a few that had
originally used a single-tab indentation (rather than our usual style of
aligning with the open paren). I also rewrapped a couple of obvious
cases (e.g., where previously too-long lines became short enough to fit
on one), but I wasn't aggressive about it. In cases broken to three or
more lines, the grouping of arguments is sometimes meaningful, and it
wasn't worth my time or reviewer time to ponder each case individually.

We eventually want to drop the argv_array name and just use strvec

Because of our preprocessor compat layer, the names are interchangeable

This patch converts all of the remaining files, as the resulting diff is

The conversion was done purely mechanically with:

We want to eventually drop the use of the "argv_array" name in favor of
"strvec." Unlike most other uses of the name, this one is embedded in a
function name, so the definition and all of the callers need to be

The name "argv-array" isn't very good, because it describes what the
data type can be used for (program argument arrays), not what it
actually is (a dynamically-growing string array that maintains a
NULL-terminator invariant). This leads to people being hesitant to use
it for other cases where it would actually be a good fit. The existing
name is also clunky to use. It's overly long, and the name often leads
to saying things like "argv.argv" (i.e., the field names overlap with
variable names, since they're describing the use, not the type). Let's
give it a more neutral name.
I settled on "strvec" because "vector" is the name for a dynamic array
type in many programming languages. "strarray" would work, too, but it's
longer and a bit more awkward to say (and don't we all say these things
in our mind as we type them?).
A more extreme direction would be a generic data structure which stores
a NULL-terminated of _any_ type. That would be easy to do with void
pointers, but we'd lose some type safety for the existing cases. Plus it
raises questions about memory allocation and ownership. So I limited
myself here to changing names only, and not semantics. If we do find a
use for that more generic data type, we could perhaps implement it at a
lower level and then provide type-safe wrappers around it for strings.
But that can come later.
This patch does the minimum to convert the struct and function names in
the header and implementation, leaving a few things for follow-on
patches:
- files retain their original names for now
- struct field names are retained for now
- there's a preprocessor compat layer that lets most users remain the
same for now. The exception is headers which made a manual forward
declaration of the struct. I've converted them (and their dependent
function declarations) here.

On most 64-bit platforms, "int" is significantly smaller than a size_t,
which could lead to integer overflow and under-allocation of the array.
It's probably impossible to trigger in practice, as it would imply on
the order of 2^32 individual allocations. Even if was possible to grow
an array in that way (and we typically only use it for sets of strings,
like command line options), each allocation needs a pointer, malloc
overhead, etc. You'd quite likely run out of RAM before succeeding in
such an overflow.
But all that hand-waving aside, it's easy enough to use the correct
type, so let's do so.

need to store pseudorefs in GIT_DIR".
Refs such as REBASE_HEAD are read through the ref backend. This can
only work consistently if they are written through the ref backend as
well. Tooling that works directly on files under .git should be
updated to use git commands to read refs instead.
The following behaviors change:
* Updates to pseudorefs (eg. ORIG_HEAD) with
core.logAllRefUpdates=always will create reflogs for the pseudoref.
* non-HEAD pseudoref symrefs are also dereferenced on deletion. Update
t1405 accordingly.

In our test suite, when 'git p4' invokes a Git command as a
subprocesses, then it should run the 'git' binary we are testing.
Unfortunately, this is not the case in the 'linux-clang' and
'linux-gcc' jobs on Travis CI, where 'git p4' runs the system
'/usr/bin/git' instead.
Travis CI's default Linux image includes 'pyenv', and all Python
invocations that involve PATH lookup go through 'pyenv', e.g. our
'PYTHON_PATH=$(which python3)' sets '/opt/pyenv/shims/python3' as
PYTHON_PATH, which in turn will invoke '/usr/bin/python3'. Alas, the
'pyenv' version included in this image is buggy, and prepends the
directory containing the Python binary to PATH even if that is a
system directory already in PATH near the end. Consequently, 'git p4'
in those jobs ends up with its PATH starting with '/usr/bin', and then
runs '/usr/bin/git'.
So use the absolute paths '/usr/bin/python{2,3}' explicitly when
setting PYTHON_PATH in those Linux jobs to avoid the PATH lookup and
thus the bogus 'pyenv' from interfering with our 'git p4' tests.
Don't bother with special-casing Travis CI: while this issue doesn't
affect the corresponding Linux jobs on GitHub Actions, both CI systems
use Ubuntu LTS-based images, so we can safely rely on these Python
paths.

When we invoke a remote transport helper and pass an option with an
argument, we quote the argument as a C-style string if necessary. This
is the case for the cas option, which implements the --force-with-lease
command-line flag, when we're passing a non-ASCII refname.
However, the remote curl helper isn't designed to parse such an
argument, meaning that if we try to use --force-with-lease with an HTTP
push and a non-ASCII refname, we get an error like this:
error: cannot parse expected object name '0000000000000000000000000000000000000000"'
Note the double quote, which get_oid has reminded us is not valid in an
hex object ID.
Even if we had been able to parse it, we would send the wrong data to
the server: we'd send an escaped ref, which would not behave as the user
wanted and might accidentally result in updating or deleting a ref we
hadn't intended.
Since we need to expect a quoted C-style string here, just check if the
first argument is a double quote, and if so, unquote it. Note that if
the refname contains a double quote, then we will have double-quoted it
already, so there is no ambiguity.
We test for this case only in the smart protocol, since the DAV-based
protocol is not capable of handling this capability. We use UTF-8
because this is nicer in our tests and friendlier to Windows, but the
code should work for all non-ASCII refs.
While we're at it, since the name of the option is now well established
and isn't going to change, let's inline it instead of using the #define
constant.

specifically `treat_path()`, to check against any pathspecs so that we
could simplify the callers.
But in doing so, we added a slightly-too-early return for the "excluded"
case. We end up not checking the pathspecs, meaning we return
`path_excluded` when maybe we should return `path_none`. As a result,
`git status --ignored -- pathspec` might show paths that don't actually
match "pathspec".
Move the "excluded" check down to after we've checked any pathspecs.
