This test intentionally breaks the &&-chain when using `expr` to parse
"[<path>]:<ref>" since the pattern matching operation will return 1
(failure) when <path> is empty even though an empty <path> is legitimate
in this test and should not cause the test to fail. However, it is
possible to parse the input without breaking the &&-chain by using shell
parameter expansion (i.e. `${i%%...}`). Other ways to avoid the problem
would be `{ expr $i : ... ||:; }` or test_might_fail(), however,
parameter expansion seems simplest.
IMPLEMENTATION NOTE
The rewritten `if` expression:
if test "$ref" = "${ref#refs/remotes/}"`; then continue; fi
is perhaps a bit subtle. At first glance, it looks like it will
`continue` the loop if $ref starts with "refs/remotes/", but in fact
it's the opposite: the loop will `continue` if $ref does not start with
"refs/remotes/".
In the original, `expr` would only match if the ref started with
"refs/remotes/", and $ref would end up empty if it didn't, so `test -z`
would `continue` the loop if the ref did not start with "refs/remotes/".
With parameter expansion, ${ref#refs/remotes/} attempts to strip
"refs/remotes/" from $ref. If it fails, meaning that $ref does not start
with "refs/remotes/", then the expansion will just be $ref unchanged,
and it will `continue` the loop. On the other hand, if stripping
succeeds, meaning that $ref begins with "refs/remotes/", then the
expansion will be the value of $ref with "refs/remotes/" removed, hence
`continue` will not be taken.

This test populates its `expect` file solely by appending content but
fails to ensure that the file starts out empty. The test succeeds only
because no earlier test populated a file of the exact same name, however
this is an accident waiting to happen. Make the test more robust by
ensuring that it contains exactly the intended content.
While at it, simplify the implementation via a straightforward `sed`
application and by avoiding dropping out of the single-quote context
within the test body (thus eliminating a hard-to-digest combination of
apostrophes and backslashes).

To create its "expect" file, this test pipes into `sort` the output of
`git for-each-ref` and a copy of that same output but with a minor
textual transformation applied. To do so, it employs a subshell and
commands `cat` and `sed` even though the same result can be accomplished
by `sed` alone (without a subshell).

Several tests assign the output of `$(...)` command substitution to an
"expect" variable, taking advantage of the fact that `$(...)` folds out
the final line terminator while leaving internal line terminators
intact. They do this because the "actual" string with which "expect"
will be compared is shaped the same way. However, this intent (having
internal line terminators, but no final line terminator) is not
necessarily obvious at first glance and may confuse casual readers. The
intent can be made more obvious by using `printf` instead, with which
line termination is stated clearly:
printf "sixth\nthird"
In fact, many other tests in this script already use `printf` for
precisely this purpose, thus it is an established pattern. Therefore,
convert these tests to employ `printf`, as well.
While at it, modernize the tests to use test_cmp() to compare the
expected and actual output rather than using the semi-deprecated
`verbose test "$x" = "$y"`.

Although `exit 1` is the proper way to signal a test failure from within
a subshell, its use outside any subshell should be avoided since it
aborts the entire script rather than aborting only the failed test.
Instead, a simple `return 1` is the proper idiom for signaling failure
outside a subshell since it aborts only the test in question, not the
entire script.

On Microsoft Windows, a directory name should never end with a period.
Quoting from Microsoft documentation[1]:
Do not end a file or directory name with a space or a period.
Although the underlying file system may support such names, the
Windows shell and user interface does not.
Naming a directory with a trailing period is indeed perilous:
% git init foo
% cd foo
% mkdir a.
% git status
warning: could not open directory 'a./': No such file or directory
The t1010 "setup" test:
for d in a a. a0
do
mkdir "$d" && echo "$d/one" >"$d/one" &&
git add "$d"
done &&
runs afoul of this Windows limitation, as can be observed when running
the test verbosely:
error: open("a./one"): No such file or directory
error: unable to index file 'a./one'
fatal: adding files failed
The reason this problem has gone unnoticed for so long is twofold.
First, the failed `git add` is swallowed silently because the loop is
not terminated explicitly by `|| return 1` to signal the failure.
Second, none of the tests in this script care about the literal
directory names ("a", "a.", "a0") or the specific number of tree
entries. They care instead about the order of entries in the tree, and
that the tree synthesized in the index and created by `git write-tree`
matches the tree created by the output of `git ls-tree` fed into `git
mktree`, thus the absence of "a./one" has no impact on the tests.
Skipping these tests on Windows by, for instance, checking the
FUNNYNAMES predicate would avoid the problem, however, the funny-looking
name is not what is being tested here. Rather, the tests are about
checking that `git mktree` produces stable results for various input
conditions, such as when the input order is not consistent or when an
object is missing.
Therefore, resolve the problem simply by using a directory name which is
legal on Windows and sorts the same as "a.". While at it, add the
missing `|| return 1` to the loop body in order to catch this sort of
problem in the future.

If valid-before/after dates are configured for this signatures key in the
allowedSigners file then the verification should check if the key was valid at
the time the commit was made. This allows for graceful key rollover and
revoking keys without invalidating all previous commits.
This feature needs openssh > 8.8. Older ssh-keygen versions will simply
ignore this flag and use the current time.
Strictly speaking this feature is available in 8.7, but since 8.7 has a
bug that makes it unusable in another needed call we require 8.8.
Timestamp information is present on most invocations of check_signature.
However signer ident is not. We will need the signer email / name to be able
to implement "Trust on first use" functionality later.
Since the payload contains all necessary information we can parse it
from there. The caller only needs to provide us some info about the
payload by setting payload_type in the signature_check struct.
- Add payload_type field & enum and payload_timestamp to struct
signature_check
- Populate the timestamp when not already set if we know about the
payload type
- Pass -Overify-time={payload_timestamp} in the users timezone to all
ssh-keygen verification calls
- Set the payload type when verifying commits
- Add tests for expired, not yet valid and keys having a commit date
outside of key validity as well as within

To be able to extend the payload metadata with things like its creation
timestamp or the creators ident we remove the payload parameters to
check_signature() and use the already existing sigc->payload field
instead, only adding the length field to the struct. This also allows
us to get rid of the xmemdupz() calls in the verify functions. Since
sigc is now used to input data as well as output the result move it to
the front of the function list.
- Add payload_length to struct signature_check
- Populate sigc.payload/payload_len on all call sites
- Remove payload parameters to check_signature()
- Remove payload parameters to internal verify_* functions and use sigc
instead
- Remove xmemdupz() used for verbose output since payload is now already
populated.
