The style of t9700-perl-git.sh is old. There are 3 problems:
* A title is not on the same line with test_expect_success command.
* A test body is indented by whitespaces.
* There are whitespaces after redirect operators.
Modernize test scripts by:
* Combine the title with test_expect_success command.
* Replace whitespace indents with TAB.
* Delete whitespaces after redirect operators.

If we encounter an error in an index file, we may say something like:
error: 1234abcd: invalid sha1 pointer in resolve-undo
But if you have multiple worktrees, each with its own index, it can be
very helpful to know which file had the problem. So let's pass that path
down through the various index-fsck functions and use it where
appropriate. After this patch you should get something like:
error: 1234abcd: invalid sha1 pointer in resolve-undo of .git/worktrees/wt/index
That's a bit verbose, but since the point is that you shouldn't see this
normally, we're better to err on the side of more details.
I've also added the index filename to the name used by "fsck
--name-objects", which will show up if we find the object to be missing,
etc. This is bending the rules a little there, as the option claims to
write names that can be fed to rev-parse. But there is no revision
syntax to access the index of another worktree, so the best we can do is
make up something that a human will probably understand.
I did take care to retain the existing ":file" syntax for the current
worktree. So the uglier output should kick in only when it's actually
necessary. See the included tests for examples of both forms.

We check the index file for the main worktree, but completely ignore the
index files in other worktrees. These should be checked, too, as they
are part of the repository state (and in particular, errors in those
index files may cause repo-wide operations like "git gc" to complain).

Things should be able to depend on object.h without pulling in all of
cache.h. Move an enum to allow this.
Note that a couple files previously depended on things brought in
through cache.h indirectly (revision.h -> commit.h -> object.h ->
cache.h). As such, this change requires making existing dependencies
more explicit in half a dozen files. The inclusion of strbuf.h in
some headers if of particular note: these headers directly embedded a
strbuf in some new structs, meaning they should have been including
strbuf.h all along but were indirectly getting the necessary
definitions.

These defines and enum are all oid-related and as such seem to make
more sense being included in hash.h. Further, moving them there
allows us to remove some includes of cache.h in other files.
The change to line-log.h might look unrelated, but line-log.h includes
diffcore.h, which previously included cache.h, which included the
kitchen sink. Since this patch makes diffcore.h no longer include
cache.h, the compiler complains about the 'struct string_list *'
function parameter. Add a forward declaration for struct string_list to

If the user omits the space between "-C" and the commit in a fixup
command then it is parsed as an ordinary fixup and the commit message is
not updated as it should be. Fix this by making the space between "-C"
and "<commit>" optional as it is for the "merge" command.
Note that set_replace_editor() is changed to set $GIT_SEQUENCE_EDITOR
instead of $EDITOR in order to be able to replace the todo list and
reword commits with $FAKE_COMMIT_MESSAGE. This is safe as all the
existing users are using set_replace_editor() to replace the todo list.

When matching an unabbreviated command is_command() only does a prefix
match which means it parses "pickled" as TODO_PICK. parse_insn_line()
does error out because is_command() only advances as far as the end of
"pick" so it looks like the command name is not followed by a space but
the error message is "missing arguments for pick" rather than telling
the user that the "pickled" is not a valid command.
Fix this by ensuring the match is follow by whitespace or the end of the
string as we already do for abbreviated commands. The (*bol = p) at the
end of the condition is a bit cute for my taste but I decided to leave
it be for now. Rather than add new tests the existing tests for bad
commands are adapted to use a bad command name that triggers the prefix
matching bug.

The point of t5559 is run the regular t5551 tests with HTTP/2. But it
does so with the "h2c" protocol, which uses cleartext upgrades from
HTTP/1.1 to HTTP/2 (rather than learning about HTTP/2 support during the
TLS negotiation).
This has a few problems:
- it's not very indicative of the real world. In practice, most servers
that support HTTP/2 will also support TLS.
- support for upgrading does not seem as robust. In particular, we've
run into bugs in some versions of Apache's mod_http2 that trigger
only with the upgrade mode. See:
https://lore.kernel.org/git/Y8ztIqYgVCPILJlO@coredump.intra.peff.net/
So the upside is that this change makes our HTTP/2 tests more robust and
more realistic. The downside is that if we can't set up SSL for any
reason, we'll skip the tests (even though you _might_ have been able to
run the HTTP/2 tests the old way). We could probably have a conditional
fallback, but it would be complicated for little gain, and it's not even
clear it would help (i.e., would any test environment even have HTTP/2
but not SSL support?).

One test needs to be tweaked in order for t5559 to pass with SSL/TLS set
up. When we make our initial clone, we check that the curl trace of
requests is what we expected. But we need to fix two things:
- along with ignoring "data" lines from the trace, we need to ignore
"SSL data" lines
- when TLS is used, the server is able to tell the client (via ALPN)
that it supports HTTP/2 before the first HTTP request is made. So
rather than request an upgrade using an HTTP header, it can just
speak HTTP/2 immediately
With this patch, running:
LIB_HTTPD_SSL=1 ./t5559-http-fetch-smart-http2.sh
works, whereas it did not before.

Commit 73c49a4474 (t: run t5551 tests with both HTTP and HTTP/2,
2022-11-11) added Apache config to enable HTTP/2. However, it only
enabled the "h2c" protocol, which allows cleartext HTTP/2 (generally
based on an upgrade header during an HTTP/1.1 request). This is what
t5559 is generally testing, since by default we don't set up SSL/TLS.
However, it should be possible to run t5559 with LIB_HTTPD_SSL set. In
that case, Apache will advertise support for HTTP/2 via ALPN during the
TLS handshake. But we need to tell it support "h2" (the non-cleartext
version) to do so. Without that, then curl does not even try to do the
HTTP/1.1 upgrade (presumably because after seeing that we did TLS but
didn't get the ALPN indicator, it assumes it would be fruitless).

When the HTTP tests are run with LIB_HTTPD_SSL in the environment, then
we access the test server as https://. This causes expect_askpass to
complain, because it tries to blindly match "http://" in the prompt
shown to the user. We can adjust this to use $HTTPD_PROTO, which is set
during the setup phase.
Note that this is enough for t5551 and t5559 to pass when run with
https, but there are similar problems in other scripts that will need to
be fixed before the whole suite can run with LIB_HTTPD_SSL.

We pick apart a curl trace, looking for "=> Send header:" and so on, and
matching against an expected set of requests and responses. We remove
"== Info" lines entirely. However, our parser is fooled when running the
test with LIB_HTTPD_SSL on Ubuntu 20.04 (as found in our linux-gcc CI
job), as curl hands us an "Info" buffer with a newline, and we get:
== Info: successfully set certificate verify locations:
== Info: CAfile: /etc/ssl/certs/ca-certificates.crt
CApath: /etc/ssl/certs
=> Send SSL data[...]
which results in the "CApath" line ending up in the cleaned-up output,
causing the test to fail.
Arguably the tracing code should detect this and put it on two separate
"== Info" lines. But this is actually a curl bug, fixed by their
80d73bcca (tls: provide the CApath verbose log on its own line,
2020-08-18). It's simpler to just work around it here.
Since we are using GIT_TRACE_CURL, every line should just start with one
of "<=", "==", or "=>", and we can throw away anything else. In fact, we
can just replace the pattern for deleting "*" lines. Those were from the
old GIT_CURL_VERBOSE output, but we switched over in 14e24114d9
(t5551-http-fetch-smart.sh: use the GIT_TRACE_CURL environment var,
2016-09-05).

After making a request, we check that it stored the expected cookies.
This depends on the protocol version, because the cookies we store
depend on the exact requests we made (and for ls-remote, v2 will always
hit /git-upload-pack to get the refs, whereas v0 is happy with the
initial ref advertisement).
As a result, hardly anybody runs this test, as you'd have to manually
set GIT_TEST_PROTOCOL_VERSION=0 to do so.
Let's teach it to handle both protocol versions. One way to do this
would be to make the expectation conditional on the protocol used. But
there's a simpler solution. The reason that v0 doesn't hit
/git-upload-pack is that ls-remote doesn't fetch any objects. If we
instead do a fetch (making sure there's an actual object to grab), then
both v0 and v2 will hit the same endpoints and set the same cookies.
Note that we do have to clean up our new tag here; otherwise it confuses
the later "clone 2,000 tags" test.

After making an HTTP request that should store cookies, we check that
the expected values are in the cookie file. We don't want to look at the
whole file, because it has noisy comments at the top that we shouldn't
depend on. But we strip out the interesting bits using "tail -3", which
is brittle. It requires us to put an extra blank line in our expected
output, and it would fail to notice any reordering or extra content in
the cookie file.
Instead, let's just grep for non-blank lines that are not comments,
which more directly describes what we're interested in.

We perform a clone and a fetch, and then check that we saw the expected
requests in Apache's access log. In the v2 protocol, there will be one
extra request to /git-upload-pack for each operation (since the initial
/info/refs probe is just used to upgrade the protocol).
As a result, this test is a noop unless the use of the v0 protocol is
forced. Which means that hardly anybody runs it, since you have to do so
manually.
Let's update it to handle v2 and run it always. We could do this by just
conditionally adding in the extra POST lines. But if we look at the
origin of the test in 7da4e2280c (test smart http fetch and push,
2009-10-30), the point is really just to make sure that the smart
git-upload-pack service was used at all. So rather than counting up the
individual requests, let's just make sure we saw each of the expected
types. This is a bit looser, but makes maintenance easier.
Since we're now matching with grep, we can also loosen the HTTP/1.1
match, which allows this test to pass when run with HTTP/2 via t5559.
That lets:
GIT_TEST_PROTOCOL_VERSION=0 ./t5559-http-fetch-smart-http2.sh
run to completion, which previously failed (and of course it works if
you use v2, as well).

After cloning an http repository, we check the curl trace to make sure
the expected requests were made. But since the expected trace was never
updated to handle v2, it is only run when you ask the test suite to run
in v0 mode (which hardly anybody does).
Let's update it to handle both protocols. This isn't too hard since v2
just sends an extra header and an extra request. So we can just annotate
those extra lines and strip them out for v0 (and drop the annotations
for v2). I didn't bother handling v1 here, as it's not really of
practical interest (it would drop the extra v2 request, but still have
the "git-protocol" lines).
There's a similar tweak needed at the end. Since we check the
"accept-encoding" value loosely, we grep for it rather than finding it
in the verbatim trace. This grep insists that there are exactly 2
matches, but of course in v2 with the extra request there are 3. We
could tweak the number, but it's simpler still to just check that we saw
at least one match. The verbatim check already confirmed how many
instances of the header we have; we're really just checking here that
"gzip" is in the value (it's possible, of course, that the headers could
have different values, but that seems like an unlikely bug).

In the "clone http repository" test, we check the curl trace to make
sure the expected requests were made. This whole script was marked to
handle only the v0 protocol in d790ee1707 (tests: fix protocol version
for overspecifications, 2019-02-25). That makes sense, since v2 requires
an extra request, so tests as specific as this would fail unless
modified.
Later, in preparation for v2 becoming the default, this was tweaked by
8a1b0978ab (test: request GIT_TEST_PROTOCOL_VERSION=0 when appropriate,
2019-12-23). There we run the trace check only if the user has
explicitly asked to test protocol version 0. But it also forced the
clone itself to run with the v0 protocol.
This makes the check for "can we expect a v0 trace" silly; it will
always be v0. But much worse, it means that the clone we are testing is
not like the one that normal users would run. They would use the
defaults, which are now v2. And since this is supposed to be a basic
check of clone-over-http, we should do the same.
Let's fix this by dropping the extra v0 override. The test still passes
because the trace checking only kicks in if we asked to use v0
explicitly (this is the same as before; even though we were running a v0
clone, unless you specifically set GIT_TEST_PROTOCOL_VERSION=0, the
trace check was always skipped).

We check that the curl trace of a clone has the lines we expect, but
this won't work when we run the test under t5559, because a few details
are different under HTTP/2 (but nobody noticed because it only happens
when you manually set GIT_TEST_PROTOCOL_VERSION to "0").
We can handle both HTTP protocols with a few tweaks:
- we'll drop the HTTP "101 Switching Protocols" response, as well as
various protocol upgrade headers. These details aren't interesting
to us. We just want to make sure the correct protocol was used (and
we do in the main request/response lines).
- successful HTTP/2 responses just say "200" and not "200 OK"; we can
normalize these
- replace HTTP/1.1 with a variable in the request/response lines. We
can use the existing $HTTP_PROTO for this, as it's already set to
"HTTP/2" when appropriate. We do need to tweak the fallback value to
"HTTP/1.1" to match what curl will write (prior to this patch, the
fallback value didn't matter at all; we only checked if it was the
literal string "HTTP/2").
Note that several lines still expect HTTP/1.1 unconditionally. The first
request does so because the client requests an upgrade during the
request. The POST request and response do so because you can't do an
upgrade if there is a request body. (This will all be different if we
trigger HTTP/2 via ALPN, but the tests aren't yet capable of that).
This is enough to let:
GIT_TEST_PROTOCOL_VERSION=0 ./t5559-http-fetch-smart-http2.sh
pass the "clone http repository" test (but there are some other failures
later on).

There's a test in t5551 which checks the curl trace (after simplifying
it a bit). It doesn't work with HTTP/2, because in that case curl
outputs all of the headers in lower-case. Even though this test is run
with HTTP/2 by t5559, nobody has noticed because checking the trace only
happens if GIT_TEST_PROTOCOL_VERSION is manually set to "0".
Let's fix this by lower-casing all of the header names in the trace, and
then checking for those in our expected code (this is easier than making
HTTP/2 traces look like HTTP/1.1, since HTTP/1.1 uses title-casing).
Sadly, we can't quite do this in our existing sed script. This works if
you have GNU sed:
s/^\\([><]\\) \\([A-Za-z0-9-]*:\\)/\1 \L\2\E/
but \L is a GNU-ism, and I don't think there's a portable solution. We
could just "tr A-Z a-z" on the way in, of course, but that makes the
non-header parts harder to read (e.g., lowercase "post" requests). But
to paraphrase Baron Munchausen, I have learned from experience that a
modicum of Perl can be most efficacious.
Note that this doesn't quite get the test passing with t5559; there are
more fixes needed on top.

Commit b0c4adcdd7 (remote-curl: send Accept-Language header to server,
2022-07-11) added tests to make sure the header is sent via HTTP.
However, it checks in two places:
1. In the expected trace output, we check verbatim for the header and
its value.
2. Afterwards, we grep for the header again in the trace file.
This (2) is probably cargo-culted from the earlier grep for
Accept-Encoding. It is needed for the encoding because we smudge the
value of that header when doing the verbatim check; see 1a53e692af
(remote-curl: accept all encodings supported by curl, 2018-05-22).
But we don't do so for the language header, so any problem that the
"grep" would catch in (2) would already have been caught by (1).

Commit 9ee6bcd398 (t5541-http-push: add test for URLs with trailing
slash, 2010-04-08) added a test that clones a URL with a trailing slash,
and confirms that we don't send a doubled slash (like "$url//info/refs")
to the server.
But this test makes no sense in t5541, which is about pushing. It should
have been added in t5551. Let's move it there.
But putting it at the end is tricky, since it checks the entire contents
of the Apache access log. We could get around this by clearing the log
before our test. But there's an even simpler solution: just make sure no
doubled slashes appear in the log (fortunately, "http://" does not
appear in the log itself).
As a bonus, this also lets us drop the check for the v0 protocol (which
is otherwise necessary since v2 makes multiple requests, and
check_access_log insists on exactly matching the number of requests,
even though we don't care about that here).

We have a test which checks to see if a request to git-receive-pack was
made. Originally, it was checking the entire set of requests made in the
script so far, including clones, and thus it would break when run with
the v2 protocol (since that implies an extra request for fetches).
Since the previous commit, though, we are only checking the requests
made by a single push. And since there is no v2 push protocol, the test
now passes no matter what's in GIT_TEST_PROTOCOL_VERSION. We can just
run it all the time.

There's a test in t5541 that confirms that "git push" makes two requests
(a GET to /info/refs, and a POST to /git-receive-pack). However, it's a
noop unless GIT_TEST_PROTOCOL_VERSION is set to "0", due to 8a1b0978ab
(test: request GIT_TEST_PROTOCOL_VERSION=0 when appropriate,
2019-12-23).
This means that almost nobody runs it. And indeed, it has been broken
since b0c4adcdd7 (remote-curl: send Accept-Language header to server,
2022-07-11). But the fault is not in that commit, but in how brittle the
test is. It runs after several operations have been performed, which
means that it expects to see the complete set of requests made so far in
the script. Commit b0c4adcdd7 added a new test, which means that the
"used receive-pack service" test must be updated, too.
Let's fix this by making the test less brittle. We'll move it higher in
the script, right after the first push has completed. And we'll clear
the access log right before doing the push, so we'll see only the
requests from that command.
This is technically testing less, in that we won't check that all of
those other requests also correctly used smart http. But there's no
particular reason think that if the first one did, the others wouldn't.
After this patch, running:
GIT_TEST_PROTOCOL_VERSION=0 ./t5541-http-push-smart.sh
passes, whereas it did not before.

Some passwords have an expiry date known at generation. This may be
years away for a personal access token or hours for an OAuth access
token.
When multiple credential helpers are configured, `credential fill` tries
each helper in turn until it has a username and password, returning
early. If Git authentication succeeds, `credential approve`
stores the successful credential in all helpers. If authentication
fails, `credential reject` erases matching credentials in all helpers.
Helpers implement corresponding operations: get, store, erase.
The credential protocol has no expiry attribute, so helpers cannot
store expiry information. Even if a helper returned an improvised
expiry attribute, git credential discards unrecognised attributes
between operations and between helpers.
This is a particular issue when a storage helper and a
credential-generating helper are configured together:
[credential]
helper = storage # eg. cache or osxkeychain
helper = generate # eg. oauth
`credential approve` stores the generated credential in both helpers
without expiry information. Later `credential fill` may return an
expired credential from storage. There is no workaround, no matter how
clever the second helper. The user sees authentication fail (a retry
will succeed).
Introduce a password expiry attribute. In `credential fill`, ignore
expired passwords and continue to query subsequent helpers.
In the example above, `credential fill` ignores the expired password
and a fresh credential is generated. If authentication succeeds,
`credential approve` replaces the expired password in storage.
If authentication fails, the expired credential is erased by
`credential reject`. It is unnecessary but harmless for storage
helpers to self prune expired credentials.
Add support for the new attribute to credential-cache.
Eventually, I hope to see support in other popular storage helpers.

As mentioned in 'git-range-diff.txt': "`git range-diff` also accepts the
regular diff options (see linkgit:git-diff[1])...", but '--abbrev' is not
in the "regular" scope.
In Git, the "abbrev" of an object may not be a fixed value in different
repositories, depending on the needs of the them(Linus mentioned in
e6c587c7 in 2016: "the Linux kernel project needs 11 to 12 hexdigits"
at that time ), that's why a user may want to display abbrev according
to a specified length.
Although a similar effect can be achieved through configuration (like:
git -c core.abbrev=<abbrev>), but based on ease of use (many users may not
know that the -c option can be specified) and the description in existing
document, supporting users to directly use '--abbrev', could be a good way.

prior to 51243f9 (run-command API: don't fall back on online_cpus(),
2022-10-12) `git fetch --multiple --jobs=0` would choose some default amount
of jobs, similar to `git -c fetch.parallel=0 fetch --multiple`. While our
documentation only ever promised that `fetch.parallel` would fall back to a
"sensible default", it makes sense to do the same for `--jobs`. So fall back
to online_cpus() and not BUG() out.
This fixes https://github.com/git-for-windows/git/issues/4302

It can be useful to specify diff algorithms per file type. For example,
one may want to use the minimal diff algorithm for .json files, another
for .c files, etc.
The diff machinery already checks attributes for a diff driver. Teach
the diff driver parser a new type "algorithm" to look for in the
config, which will be used if a driver has been specified through the
attributes.
Enforce precedence of the diff algorithm by favoring the command line
option, then looking at the driver attributes & config combination, then
finally the diff.algorithm config.
To enforce precedence order, use a new `ignore_driver_algorithm` member
during options parsing to indicate the diff algorithm was set via command
line args.

Check that the argument to the "label" and "update-ref" commands is a
valid refname when the todo list is parsed rather than waiting until the
command is executed. This means that the user can deal with any errors
at the beginning of the rebase rather than having it stop halfway
through due to a typo in a label name. The "update-ref" command is
changed to reject single level refs as it is all to easy to type
"update-ref branch" which is incorrect rather than "update-ref
refs/heads/branch"
Note that it is not straight forward to check the arguments to "reset"
and "merge" commands as they may be any revision, not just a refname and
we do not have an equivalent of check_refname_format() for revisions.

In 647982bb71 (delta-islands: free island_marks and bitmaps, 2023-02-03)
we have introduced logic to free `island_marks` in order to reduce heap
memory usage in git-pack-objects(1). This commit is causing segfaults in
the case where this Git command does not load delta islands at all, e.g.
when reading object IDs from standard input. One such crash can be hit
when using repacking multi-pack-indices with delta islands enabled.
The root cause of this bug is that we unconditionally dereference the
`island_marks` variable even in the case where it is a `NULL` pointer,
which is fixed by making it conditional. Note that we still leave the
logic in place to set the pointer to `-1` to detect use-after-free bugs
even when there are no loaded island marks at all.

Allow users to specify the modification time of archive entries. The
new option --mtime uses approxidate() to parse a time specification and
overrides the default of using the current time for trees and the commit
time for tags and commits. It can be used to create a reproducible
archive for a tree, or to use a specific mtime without creating a commit
with GIT_COMMITTER_DATE set.
This implementation doesn't support the negated form of the new option,
i.e. --no-mtime is not accepted. It is not possible to have no mtime at
all. We could use the Unix epoch or revert to the default behavior, but
since negation is not necessary for the intended use it's left undecided
for now.

When a lower precedence configuration file (e.g. /etc/gitconfig)
defines format.attach in any way, there was no way to disable it in
a more specific configuration file (e.g. $HOME/.gitconfig).
Change the behaviour of setting it to an empty string. It used to
mean that the result is still a multipart message with only dashes
used as a multi-part separator, but now it resets the setting to
the default (which would be to give an inline patch, unless other
command line options are in effect).

The symlink setup in t0066 makes several directories with links, dir4
through dir6. But ever since dir5 was introduced in fa1da7d2ee
(dir-iterator: add flags parameter to dir_iterator_begin, 2019-07-10),
it has never actually been used. It was left over from an earlier
iteration of the patch which tried to handle recursive symlinks
specially, as seen in:
https://lore.kernel.org/git/20190502144829.4394-7-matheus.bernardino@usp.br/
It's not hurting any of the existing tests to be there, but the extra
setup is confusing to anybody trying to read and understand the tests.
Let's drop the extra directory, and we'll rename "dir6" to "dir5" so
nobody wonders whether the gap in naming is important.

We do not test our http proxy functionality at all in the test suite, so
this is a pretty big blind spot. Let's at least add a basic check that
we can go through an authenticating proxy to perform a clone.
A few notes on the implementation:
- I'm using a single apache instance to proxy to itself. This seems to
work fine in practice, and we can check with a test that this rather
unusual setup is doing what we expect.
- I've put the proxy tests into their own script, and it's the only
one which loads the apache proxy config. If any platform can't
handle this (e.g., doesn't have the right modules), the start_httpd
step should fail and gracefully skip the rest of the script (but all
the other http tests in existing scripts will continue to run).
- I used a separate passwd file to make sure we don't ever get
confused between proxy and regular auth credentials. It's using the
antiquated crypt() format. This is a terrible choice security-wise
in the modern age, but it's what our existing passwd file uses, and
should be portable. It would probably be reasonable to switch both
of these to bcrypt, but we can do that in a separate patch.
- On the client side, we test two situations with credentials: when
they are present in the url, and when the username is present but we
prompt for the password. I think we should be able to handle the
case that _neither_ is present, but an HTTP 407 causes us to prompt
for them. However, this doesn't seem to work. That's either a bug,
or at the very least an opportunity for a feature, but I punted on
it for now. The point of this patch is just getting basic coverage,
and we can explore possible deficiencies later.
- this doesn't work with LIB_HTTPD_SSL. This probably would be
valuable to have, as https over an http proxy is totally different
(it uses CONNECT to tunnel the session). But adding in
mod_proxy_connect and some basic config didn't seem to work for me,
so I punted for now. Much of the rest of the test suite does not
currently work with LIB_HTTPD_SSL either, so we shouldn't be making
anything much worse here.

The `FOLLOW_SYMLINKS` flag was added to the dir-iterator API in
fa1da7d2ee (dir-iterator: add flags parameter to dir_iterator_begin,
2019-07-10) in order to follow symbolic links while traversing through a
directory.
`FOLLOW_SYMLINKS` gained its first caller in ff7ccc8c9a (clone: use
dir-iterator to avoid explicit dir traversal, 2019-07-10), but it was
subsequently removed in 6f054f9fb3 (builtin/clone.c: disallow `--local`
clones with symlinks, 2022-07-28).
Since then, we've held on to the code for `DIR_ITERATOR_FOLLOW_SYMLINKS`
in the name of making minimally invasive changes during a security
embargo.
In fact, we even changed the dir-iterator API in bffc762f87
(dir-iterator: prevent top-level symlinks without FOLLOW_SYMLINKS,
2023-01-24) without having any non-test callers of that flag.
Now that we're past those security embargo(s), let's finalize our
cleanup of the `DIR_ITERATOR_FOLLOW_SYMLINKS` code and remove its
implementation since there are no remaining callers.

This test helper feeds 256kB of data at once to a single invocation
of the write(2) system call, which may be too much for some
platforms.
Call our xwrite() wrapper that knows to honor MAX_IO_SIZE limit and
cope with short writes due to EINTR instead, and die a bit more
loudly by calling die_errno() when xwrite() indicates an error.
