revisions API: extend the nascent REV_INFO_INIT macro
Have the REV_INFO_INIT macro added in [1] declare more members of
"struct rev_info" that we can initialize statically, and have
repo_init_revisions() do so with the memcpy(..., &blank) idiom
introduced in [2].
As the comment for the "REV_INFO_INIT" macro notes this still isn't
sufficient to initialize a "struct rev_info" for use yet. But we are
getting closer to that eventual goal.
Even though we can't fully initialize a "struct rev_info" with
REV_INFO_INIT it's useful for readability to clearly separate those
things that we can statically initialize, and those that we can't.
This change could replace the:
list_objects_filter_init(&revs->filter);
In the repo_init_revisions() with this line, at the end of the
REV_INFO_INIT deceleration in revisions.h:
.filter = LIST_OBJECTS_FILTER_INIT, \
But doing so would produce a minor conflict with an outstanding
topic[3]. Let's skip that for now. I have follow-ups to initialize
more of this statically, e.g. changes to get rid of grep_init(). We
can initialize more members with the macro in a future series.
The old version we currently use runs in node.js v12.x, which is being
deprecated in GitHub Actions. The new version uses node.js v16.x.
Incidentally, this also avoids the warning about the deprecated
`::set-output::` workflow command because the newer version of the
`github-script` Action uses the recommended new way to specify outputs.

ref-filter: fix parsing of signatures with CRLF and no body
This commit fixes a bug when parsing tags that have CRLF line endings, a
signature, and no body, like this (the "^M" are marking the CRs):
this is the subject^M
-----BEGIN PGP SIGNATURE-----^M
^M
...some stuff...^M
-----END PGP SIGNATURE-----^M
When trying to find the start of the body, we look for a blank line
separating the subject and body. In this case, there isn't one. But we
search for it using strstr(), which will find the blank line in the
signature.
In the non-CRLF code path, we check whether the line we found is past
the start of the signature, and if so, put the body pointer at the start
of the signature (effectively making the body empty). But the CRLF code
path doesn't catch the same case, and we end up with the body pointer in
the middle of the signature field. This has two visible problems:
- printing %(contents:subject) will show part of the signature, too,
since the subject length is computed as (body - subject)
- the length of the body is (sig - body), which makes it negative.
Asking for %(contents:body) causes us to cast this to a very large
size_t when we feed it to xmemdupz(), which then complains about
trying to allocate too much memory.
These are essentially the same bugs fixed in the previous commit, except
that they happen when there is a CRLF blank line in the signature,
rather than no blank line at all. Both are caused by the refactoring in 9f75ce3d8f (ref-filter: handle CRLF at end-of-line more gracefully,
2020-10-29).
We can fix this by doing the same "sigstart" check that we do in the
non-CRLF case. And rather than repeat ourselves, we can just use
short-circuiting OR to collapse both cases into a single conditional.
I.e., rather than:
if (strstr("\n\n"))
...found blank, check if it's in signature...
else if (strstr("\r\n\r\n"))
...found blank, check if it's in signature...
else
...no blank line found...
we can collapse this to:
if (strstr("\n\n")) ||
strstr("\r\n\r\n")))
...found blank, check if it's in signature...
else
...no blank line found...
The tests show the problem and the fix. Though it wasn't broken, I
included contents:signature here to make sure it still behaves as
expected, but note the shell hackery needed to make it work. A
less-clever option would be to skip using test_atom and just "append_cr
>expected" ourselves.

ref-filter: fix parsing of signatures without blank lines
When ref-filter is asked to show %(content:subject), etc, we end up in
find_subpos() to parse out the three major parts: the subject, the body,
and the signature (if any).
When searching for the blank line between the subject and body, if we
don't find anything, we try to treat the whole message as the subject,
with no body. But our idea of "the whole message" needs to take into
account the signature, too. Since 9f75ce3d8f (ref-filter: handle CRLF at
end-of-line more gracefully, 2020-10-29), the code instead goes all the
way to the end of the buffer, which produces confusing output.
Here's an example. If we have a tag message like this:
this is the subject
-----BEGIN SSH SIGNATURE-----
...some stuff...
-----END SSH SIGNATURE-----
then the current parser will put the start of the body at the end of the
whole buffer. This produces two buggy outcomes:
- since the subject length is computed as (body - subject), showing
%(contents:subject) will print both the subject and the signature,
rather than just the single line
- since the body length is computed as (sig - body), and the body now
starts _after_ the signature, we end up with a negative length!
Fortunately we never access out-of-bounds memory, because the
negative length is fed to xmemdupz(), which casts it to a size_t,
and xmalloc() bails trying to allocate an absurdly large value.
In theory it would be possible for somebody making a malicious tag
to wrap it around to a more reasonable value, but it would require a
tag on the order of 2^63 bytes. And even if they did, all they get
is an out of bounds string read. So the security implications are
probably not interesting.
We can fix both by correctly putting the start of the body at the same
index as the start of the signature (effectively making the body empty).
Note that this is a real issue with signatures generated with gpg.format
set to "ssh", which would look like the example above. In the new tests
here I use a hard-coded tag message, for a few reasons:
- regardless of what the ssh-signing code produces now or in the
future, we should be testing this particular case
- skipping the actual signature makes the tests simpler to write (and
allows them to run on more systems)
- t6300 has helpers for working with gpg signatures; for the purposes
of this bug, "BEGIN PGP" is just as good a demonstration, and this
simplifies the tests
Curiously, the same issue doesn't happen with real gpg signatures (and
there are even existing tests in t6300 with cover this). Those have a
blank line between the header and the content, like:
this is the subject
-----BEGIN PGP SIGNATURE-----
...some stuff...
-----END PGP SIGNATURE-----
Because we search for the subject/body separator line with a strstr(),
we find the blank line in the signature, even though it's outside of
what we'd consider the body. But that puts us unto a separate code path,
which realizes that we're now in the signature and adjusts the line back
to "sigstart". So this patch is basically just making the "no line found
at all" case match that. And note that "sigstart" is always defined (if
there is no signature, it points to the end of the buffer as you'd
expect).

t5516/t5601: be less strict about the number of credential warnings
It is unclear as to _why_, but under certain circumstances the warning
about credentials being passed as part of the URL seems to be swallowed
by the `git remote-https` helper in the Windows jobs of Git's CI builds.
Since it is not actually important how many times Git prints the
warning/error message, as long as it prints it at least once, let's just
make the test a bit more lenient and test for the latter instead of the
former, which works around these CI issues.

t5516: move plaintext-password tests from t5601 and t5516
Commit 6dcbdc0d66 (remote: create fetch.credentialsInUrl config,
2022-06-06) added tests for our handling of passwords in URLs. Since the
obvious URL to be affected is git-over-http, the tests use http. However
they don't set up a test server; they just try to access
https://localhost, assuming it will fail (because the nothing is
listening there).
This causes some possible problems:
- There might be a web server running on localhost, and we do not
actually want to connect to that.
- The DNS resolver, or the local firewall, might take a substantial
amount of time (or forever, whichever comes first) to fail to
connect, slowing down the tests cases unnecessarily.
- Since there's no server, our tests for "allow" and "warn" still
expect the clone/fetch/push operations to fail, even though in the
real world we'd expect these to succeed. We scrape stderr to see
what happened, but it's not as robust as a more realistic test.
Let's instead move these to t5551, which is all about testing http and
where we have a real server. That eliminates any issues with contacting
a strange URL, and lets the "allow" and "warn" tests confirm that the
operation actually succeeds.
It's not quite a verbatim move for a few reasons:
- we can drop the LIBCURL dependency; it's already part of
lib-httpd.sh
- we'll use HTTPD_URL_USER_PASS, etc, instead of our fake URL. To
avoid repetition, we'll add a few extra variables.
- the "https://username:@localhost" test uses a funny URL that
lib-httpd.sh doesn't provide. We'll similarly construct it in a
variable. Note that we're hard-coding the lib-httpd username here,
but t5551 already does that everywhere.
- for the "domain:port" test, the URL provided by lib-httpd is fine,
since our test server will always be on an exotic port. But we'll
confirm in the test that this is so.
- since our message-matching is done via grep, I simplified it to use
a regex, rather than trying to massage lib-httpd's variables.
Arguably this makes it more readable, too, while retaining the bits
we care about: the fatal/warning distinction, the "uses plaintext"
message, and the fact that the password was redacted.
- we'll use the /auth/ path for the repo, which shows that we are
indeed making use of the auth information when needed.
- we'll also use /smart/; most of these tests could be done via /dumb/
in t5550, but setting up pushes there requires extra effort and
dependencies. The smart protocol is what most everyone is using
these days anyway.
This patch is my own, but I stole the analysis and a few bits of the
commit message from a patch by Johannes Schindelin.

Commit 45a2686441 ("test-lib-functions: remove bug-inducing

Commit e7884b353b ("test-lib-functions: assert correct parameter count",

This history leaves us in a state where we assert that we have exactly
one argument, then go on to anyway check for arguments, echoing them
all. It's clear that we can simplify this code. We should also note that
we run `ls -ld "$1"`, so printing the filename a second time doesn't

bisect: simplify building "checkout" argument list
Reduce the scope of argv_checkout, which allows to fully build it during
initialization. Use oid_to_hex() instead of oid_to_hex_r(), because
that's simpler and using the static buffer of the former is just as safe
as the old static argv_checkout.

am: simplify building "show" argument list
Build the string array av during initialization, without any magic

run-command: fix return value comment

without updating the immediately following documentation of return codes
that only applied to the preexisting functions.
4c4066d95d (run-command: move doc to run-command.h, 2019-11-17) started
to list the functions explicitly that this paragraph applies to, but
still wrongly included child_process_init() and child_process_clear().
Remove their names from that list.

Simplify the code that builds the arguments for the "read-tree"
invocation in reset_hard() and read_empty() to remove the "verbose"
parameter.
Before 172b6428d06 (do not overwrite untracked during merge from
unborn branch, 2010-11-14) there was a "reset_hard()" function that
would be called in two places, one of those passed a "verbose=1", the
other a "verbose=0".
After 172b6428d06 when read_empty() was split off from reset_hard()
both of these functions only had one caller. The "verbose" in
read_empty() would always be false, and the one in reset_hard() would
always be true.
There was never a good reason for the code to act this way, it
happened because the read_empty() function was a copy/pasted and
adjusted version of reset_hard().
Since we're no longer conditionally adding the "-v" parameter
here (and we'd only add it for "reset_hard()" we'll be able to move to
a simpler and safer run-command API in the subsequent commit.

adjust_shared_perm(): leave g+s alone when the group does not matter
Julien Moutinho reports that in an environment where directory does
not have BSD group semantics and requires the g+s to be set (aka
FORCE_DIR_SET_GID), but the system forbids chmod() to touch the g+s
bit, adjust_shared_perm() fails even when the repository is for
private use with perm = 0600, because we unconditionally try to set
the g+s bit.
When we grant extra access based on group membership (i.e. the
directory has either g+r or g+w bit set), which group the directory
and its contents are owned by matters. But otherwise (e.g. perm is
set to 0600, in Julien's case), flipping g+s bit is not necessary.
