Replace bare grep with test_grep in test assertions across the
suite, including sourced test helpers (lib-*.sh, *-tests.sh).
test_grep prints the contents of the file being searched on
failure, making debugging easier than a bare grep which fails
silently.
Only assertion-style greps are converted: grep used as a filter
in pipelines, command substitutions, conditionals, or with
redirected I/O is left as-is with a "# lint-ok" annotation.
Existing '! test_grep' calls are rewritten to 'test_grep !' so
that the diagnostic output is preserved on failure.
test_grep requires the file it reads to exist, so '! grep'
assertions that inspect a file whose presence is conditional need
care. In t5537 the '.git/shallow' file is still present after the
repack (the client remains shallow), so the assertion is
converted like any other. In t1400 the '.git/packed-refs' file
exists only with the files backend, so its check is guarded with a
REFFILES prerequisite; the backend-agnostic 'git show-ref' check
that follows still runs under every backend. In t7450 'git~2' is
the NTFS 8.3 short name of a '..git' file and only exists
when 8.3 short-name generation is enabled, so its check is guarded
with a 'test -f' on the path and uses test_grep inside the guard,
the same shape as t1400 (a plain test_grep would BUG when the
short name is absent).
The conversion was generated using a grep-assertion linter
(greplint.pl, added in the following commit) to identify bare
grep calls at command position. To reproduce, from the t/
directory:
# Step 1: annotate the two data-filter greps (grep produces
# data, not a verdict) so the linter skips them.
sed -i '/grep -vf before commits\.raw/s/$/ # lint-ok: data filter/' \
t5326-multi-pack-bitmaps.sh
sed -i '/grep -E "^\[0-9a-f\].*|| :/s/$/ # lint-ok: data filter/' \
t5702-protocol-v2.sh
# Step 1b: two '! grep' assertions need more than a mechanical
# conversion; handle them by hand before the linter-driven steps
# below so it leaves them alone.
#
# t1400: '.git/packed-refs' is absent under reftable, so guard the
# check with REFFILES (a plain test_grep would BUG on the missing
# file):
#
# git update-ref -d HEAD $B &&

# t7450: git~2 is an NTFS 8.3 short name that exists only when
# short-name generation is enabled, so guard the check on its
# presence with 'test -f' and note in a comment why the path can

# - ! grep gitdir squatting-clone/d/a/git~2
# + if test -f squatting-clone/d/a/git~2
# + then
# + test_grep ! gitdir squatting-clone/d/a/git~2
# + fi
# Step 2: reorder pre-existing '! test_grep' to 'test_grep !'
# (must come before steps 3-4 so greplint does not see them)

Misspelt proxy URL (e.g., httt://...) did not trigger any warning
or failure, which has been corrected.
* aw/validate-proxy-url-scheme:
http: reject unsupported proxy URL schemes
|
|
An explicit proxy URL with an unrecognized scheme such as
htpp://127.0.0.1 is currently accepted.
Git parses the URL, extracts the host part, and then passes only that
host to libcurl. Because no proxy type is selected for the unknown
scheme, Git leaves libcurl at its default HTTP proxy type, so the typo
is silently treated as an HTTP proxy.
Reject proxy URLs with explicit unsupported schemes instead of silently
accepting them. Keep the existing host:port-without-scheme behavior
unchanged.
Implement the SOCKS proxy handling with a shared table-driven mapping.
Add a regression test to cover the unsupported-scheme case.

The SOCKS proxy test introduced in 0ca365c2ed4 (http: do not ignore
proxy path, 2024-08-02) creates a Unix domain socket in
`$TRASH_DIRECTORY`. When the trash directory path is long (e.g.
when running from a deeply nested worktree), the socket path can
exceed the 108-character limit for `struct sockaddr_un.sun_path` on
Linux, causing the test to fail with "Path length ... is longer
than maximum supported length (108)".
We cannot work around this using the chdir trick our own socket code
employs, because both sides of the connection are outside our control:
the socket is created by socks4-proxy.pl via Perl's IO::Socket::UNIX,
and the client side is libcurl.
Use `mktemp -d` to create a unique temporary directory with a short
path, and place the socket inside it. This avoids collisions between
concurrent test runs (e.g. `--stress`) and tmpdir-race vulnerabilities
that a static `/tmp` path would be susceptible to.

This test starts a SOCKS server in Perl in the background and then kills
it after the tests are done. However, when using zsh (in sh mode) in
the tests, the start_socks function hangs until the background process
is killed.
Note that this does not reproduce in a simple shell script, so there is
likely some interaction between job handling, our heavy use of eval in
the test framework, and possibly other complexities of our test
framework. What is clear, however, is that switching from a compound
statement to a subshell fixes the problem entirely and the test passes
with no problem, so do that.

In addition to the regular trace information produced by
CURLOPT_VERBOSE, recent curl versions can enable or disable tracing of
specific subsystems using a call to curl_global_trace().
This level of detail may or may not be useful for us in Git as mere
users of libcurl, but there's one case where we need it for a test. In
t5564, we set up a socks proxy, access it with GIT_TRACE_CURL set, and
expect to find socks-related messages in the output. This test is broken
in the release candidates for libcurl 8.16, as those socks messages are
no longer produced in the trace.
The problem bisects to curl's commit ab5e0bfddc (pytest: add SOCKS tests
and scoring, 2025-07-21). There the socks messages were moved from
generic infof() messages to the component-specific CURL_TRC_CF() system.
And so we do not see them by default, but only if "socks" is enabled as
a logging component.
Teach Git's http code to accept a component list from the
environment and pass it into curl_global_trace(). We can then use
that in the test to enable the correct component.
It should be safe to do so unconditionally. In older versions of curl
which don't support this call, setting the environment variable is a
noop. Likewise, any versions of curl which don't recognize the "socks"
component should silently ignore it. The manpage for curl_global_trace()
says this:
The config string is a list of comma-separated component names. Names
are case-insensitive and unknown names are ignored. The special name
"all" applies to all components. Names may be prefixed with '+' or '-'
to enable or disable detailed logging for a component.
The list of component names is not part of curl's public API. Names may
be added or disappear in future versions of libcurl. Since unknown
names are silently ignored, outdated log configurations does not cause
errors when upgrading libcurl. Given that, some names can be expected
to be fairly stable and are listed below for easy reference.
So this should let us make the test work on all versions without
worrying about confusing older (or newer) versions. For the same reason,
I've opted not to document this interface. This is deep internal voodoo
for which we can make no promises to users. In fact, I was tempted to
simply hard-code "socks" to let our test pass and not expose anything.
But I suspect a little run-time flexibility may come in handy in the
future when debugging or dealing with similar logging issues.
I also considered just putting "all" into such a hard-coded default. But
if you try it, you will see that many of the components are quite
verbose and likely not interesting. They would clutter up our trace
output if we enabled them by default.

The documentation for `http.proxy` describes that option, and the
environment variables it overrides, as supporting "the syntax understood
by curl". curl allows SOCKS proxies to use a path to a Unix domain
socket, like `socks5h://localhost/path/to/socket.sock`. Git should
therefore include, if present, the path part of the proxy URL in what it
passes to libcurl.

When initializing the transport helper in `transport_get()`, we
allocate the name of the helper. We neither end up transferring
ownership of the name, nor do we free it. The associated memory thus
leaks.
Fix this memory leak by freeing the string at the calling side in
`transport_get()`. `transport_helper_init()` now creates its own copy of
the string and thus can free it as required.
An alterantive way to fix this would be to transfer ownership of the
string passed into `transport_helper_init()`, which would avoid the call
to xstrdup(1). But it does make for a more surprising calling convention
as we do not typically transfer ownership of strings like this.
Mark now-passing tests as leak free.

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.
