With GIT_TRACE_CURL=1 or GIT_CURL_VERBOSE=1, sensitive headers like
"Authorization" and "Cookie" get redacted. However, since [1], curl's
h2h3 module (invoked when using HTTP/2) also prints headers in its
"info", which don't get redacted. For example,
echo 'github.com TRUE / FALSE 1698960413304 o foo=bar' >cookiefile &&
GIT_TRACE_CURL=1 GIT_TRACE_CURL_NO_DATA=1 git \
-c 'http.cookiefile=cookiefile' \
-c 'http.version=' \
ls-remote https://github.com/git/git refs/heads/main 2>output &&
grep 'cookie' output
produces output like:
23:04:16.920495 http.c:678 == Info: h2h3 [cookie: o=foo=bar]
23:04:16.920562 http.c:637 => Send header: cookie: o=<redacted>
Teach http.c to check for h2h3 headers in info and redact them using the
existing header redaction logic. This fixes the broken redaction logic
that we noted in the previous commit, so mark the redaction tests as
passing under HTTP2.

We have occasionally seen bugs that affect Git running only against an
HTTP/2 web server, not an HTTP one. For instance, b66c77a64e (http:
match headers case-insensitively when redacting, 2021-09-22). But since
we have no test coverage using HTTP/2, we only uncover these bugs in the
wild.
That commit gives a recipe for converting our Apache setup to support
HTTP/2, but:
- it's not necessarily portable
- we don't want to just test HTTP/2; we really want to do a variety of
basic tests for _both_ protocols
This patch handles both problems by running a duplicate of t5551
(labeled as t5559 here) with an alternate-universe setup that enables
HTTP/2. So we'll continue to run t5551 as before, but run the same
battery of tests again with HTTP/2. If HTTP/2 isn't supported on a given
platform, then t5559 should bail during the webserver setup, and
gracefully skip all tests (unless GIT_TEST_HTTPD has been changed from
"auto" to "yes", where the point is to complain when webserver setup
fails).
In theory other http-related test scripts could benefit from the same
duplication, but doing t5551 should give us a reasonable check of basic
functionality, and would have caught both bugs we've seen in the wild
with HTTP/2.
A few notes on the implementation:
- a script enables the server side config by calling enable_http2
before starting the webserver. This avoids even trying to load any
HTTP/2 config for t5551 (which is what lets it keep working with
regular HTTP even on systems that don't support it). This also sets
a prereq which can be used by individual tests.
- As discussed in b66c77a64e, the http2 module isn't compatible with
the "prefork" mpm, so we need to pick something else. I chose
"event" here, which works on my Debian system, but it's possible
there are platforms which would prefer something else. We can adjust
that later if somebody finds such a platform.
- The test "large fetch-pack requests can be sent using chunked
encoding" makes sure we use a chunked transfer-encoding by looking
for that header in the trace. But since HTTP/2 has its own streaming
mechanisms, we won't find such a header. We could skip the test
entirely by marking it with !HTTP2. But there's some value in making
sure that the fetch itself succeeded. So instead, we'll confirm that
either we're using HTTP2 _or_ we saw the expected chunked header.
- the redaction tests fail under HTTP/2 with recent versions of curl.
This is a bug! I've marked them with !HTTP2 here to skip them under
t5559 for the moment. Using test_expect_failure would be more
appropriate, but would require a bunch of boilerplate. Since we'll
be fixing them momentarily, let's just skip them for now to keep the
test suite bisectable, and we can re-enable them in the commit that
fixes the bug.
- one alternative layout would be to push most of t5551 into a
lib-t5551.sh script, then source it from both t5551 and t5559.
Keeping t5551 intact seemed a little simpler, as its one less level
of indirection for people fixing bugs/regressions in the non-HTTP/2
tests.

Git learned pushing submodules without pushing the superproject by
the user specifying --recurse-submodules=only through 6c656c3fe4
("submodules: add RECURSE_SUBMODULES_ONLY value", 2016-12-20) and
225e8bf778 ("push: add option to push only submodules", 2016-12-20).
For users who use this feature regularly, it is desirable to have an
equivalent configuration.
It turns out that such a configuration (push.recurseSubmodules=only) is
already supported, even though it is neither documented nor mentioned
in the commit messages, due to the way the --recurse-submodules=only
feature was implemented (a function used to parse --recurse-submodules
was updated to support "only", but that same function is used to parse
push.recurseSubmodules too). What is left is to document it and test it,
which is what this commit does.
There is a possible point of confusion when recursing into a submodule
that itself has the push.recurseSubmodules=only configuration, because
if a repository has only its submodules pushed and not itself, its
superproject can never be pushed. Therefore, treat such configurations
as being "on-demand", and print a warning message.

Fix a couple of issues in the recently merged 0f3c55d4c2b (Merge
branch 'ab/coccicheck-incremental' into next, 2022-11-08):
In copying over the "contrib/coccinelle/" rules to
".build/contrib/coccinelle/" we inadvertently ended up with a
".build/.build/contrib/coccinelle/" as well. We'd generate the
per-file patches in the former, and keep the rule and overall result
in the latter. E.g. running:
make contrib/coccinelle/free.cocci.patch COCCI_SOURCES="attr.c grep.c"
Would, per "tree -a .build" yield the following result:
.build
├── .build
│ └── contrib
│ └── coccinelle
│ └── free.cocci.patch
│ ├── attr.c
│ ├── attr.c.log
│ ├── grep.c
│ └── grep.c.log
└── contrib
└── coccinelle
├── FOUND_H_SOURCES
├── free.cocci
└── free.cocci.patch
Now we'll instead generate all of our files in
".build/contrib/coccinelle/". Fixing this required renaming the
directory where we keep our per-file patches, as we'd otherwise
conflict with the result.
Now the per-file patch directory is named e.g. "free.cocci.d". And the
end result will now be:
.build
└── contrib
└── coccinelle
├── FOUND_H_SOURCES
├── free.cocci
├── free.cocci.d
│ ├── attr.c.patch
│ ├── attr.c.patch.log
│ ├── grep.c.patch
│ └── grep.c.patch.log
└── free.cocci.patch
The per-file patches now have a ".patch" file suffix, which fixes
another issue reported against 0f3c55d4c2b: The summary output was
confusing. Before for the "make" command above we'd emit:
[...]
MKDIR -p .build/contrib/coccinelle
CP contrib/coccinelle/free.cocci .build/contrib/coccinelle/free.cocci
GEN .build/contrib/coccinelle/FOUND_H_SOURCES
MKDIR -p .build/.build/contrib/coccinelle/free.cocci.patch
SPATCH .build/.build/contrib/coccinelle/free.cocci.patch/grep.c
SPATCH .build/.build/contrib/coccinelle/free.cocci.patch/attr.c
SPATCH CAT $^ >.build/contrib/coccinelle/free.cocci.patch
CP .build/contrib/coccinelle/free.cocci.patch contrib/coccinelle/free.cocci.patch
But now we'll instead emit (identical output at the start omitted):
[...]
MKDIR -p .build/contrib/coccinelle/free.cocci.d
SPATCH grep.c >.build/contrib/coccinelle/free.cocci.d/grep.c.patch
SPATCH attr.c >.build/contrib/coccinelle/free.cocci.d/attr.c.patch
SPATCH CAT .build/contrib/coccinelle/free.cocci.d/**.patch >.build/contrib/coccinelle/free.cocci.patch
CP .build/contrib/coccinelle/free.cocci.patch contrib/coccinelle/free.cocci.patch
I.e. we have an "SPATCH" line that makes it clear that we're running
against the "{attr,grep}.c" file. The "SPATCH CAT" is then altered to
correspond to it, showing that we're concatenating the
"free.cocci.d/**.patch" files into one generated "free.cocci.patch" at
the end.

'git-bisect.sh' used to have a 'bisect_next_check' to check if we have
both good/bad, old/new terms set or not. In commit 129a6cf344
(bisect--helper: `bisect_next_check` shell function in C, 2019-01-02),
a subcommand for bisect--helper was introduced to port the check to C.
Since d1bbbe45df (bisect--helper: reimplement `bisect_run` shell
function in C, 2021-09-13), all users of 'bisect_next_check' was
re-implemented in C, this subcommand was no longer used but we forgot
to remove '--bisect-next-check'.
'git-bisect.sh' also used to have a 'bisect_write' function, whose
third positional parameter was a "nolog" flag. This flag was only used
when 'bisect_start' invoked 'bisect_write' to write the starting good
and bad revisions. Then 0f30233a11 (bisect--helper: `bisect_write`
shell function in C, 2019-01-02) ported it to C as a command mode of
'bisect--helper', which (incorrectly) added the '--no-log' option,
and convert the only place ('bisect_start') that call 'bisect_write'
with 'nolog' to 'git bisect--helper --bisect-write' with 'nolog'
instead of '--no-log', since 'bisect--helper' has command modes not
subcommands, all other command modes see and handle that option as well.
This bogus state didn't last long, however, because in the same patch
series 06f5608c14 (bisect--helper: `bisect_start` shell function
partially in C, 2019-01-02) the C reimplementation of bisect_start()
started calling the bisect_write() C function, this time with the
right 'nolog' function parameter. From then on there was no need for
the '--no-log' option in 'bisect--helper'. Eventually all bisect
subcommands were ported to C as 'bisect--helper' command modes, each
calling the bisect_write() C function instead, but when the
'--bisect-write' command mode was removed in 68efed8c8a
(bisect--helper: retire `--bisect-write` subcommand, 2021-02-03) it
forgot to remove that '--no-log' option.
'--no-log' option had never been used and it's unused now.
Let's remove --bisect-next-check and --no-log from option parsing.

Although the macOS Terminal.app is "xterm"-compatible, its corresponding
"terminfo" entries -- such as "xterm", "xterm-256color", and
"xterm-new"[1] -- neglect to mention capabilities which Terminal.app
actually supports (such as "dim text"). This oversight on Apple's part
ends up penalizing users of "good citizen" console programs which
consult "terminfo" to tailor their output based upon reported terminal
capabilities (as opposed to programs which assume that the terminal
supports ANSI codes). The same problem is present in other Apple
"terminfo" entries, such as "nsterm"[2], with which macOS Terminal.app
may be configured.
Sidestep this Apple problem by imbuing get_colors() with specific
knowledge of capabilities common to "xterm" and "nsterm", rather than
trusting "terminfo" to report them correctly. Although hard-coding such
knowledge is ugly, "xterm" support is nearly ubiquitous these days, and
Git itself sets precedence by assuming support for ANSI color codes. For
other terminal types, fall back to querying "terminfo" via `tput` as
usual.

The `label` command creates a ref refs/rewritten/<label> that the

uses lookup_commit_reference_by_name() to look up the label ref. As
lookup_commit_reference_by_name() uses the dwim rules when looking up
the label it will look for a branch named
refs/heads/refs/rewritten/<label> and return that instead of an error if
the branch exists and the label does not. Fix this by using read_ref()

The arguments to the `reset` and `merge` commands may be a label created
with a `label` command or an arbitrary commit name. The `merge` command
uses the lookup_label() function to lookup its arguments but `reset` has
a slightly different version of that function in do_reset(). Reduce this
code duplication by calling lookup_label() from do_reset() as well.
This change improves the behavior of `reset` when the argument is a
tree. Previously `reset` would accept a tree only for the rebase to
fail with

Enable the 'skip_cache_tree_update' option in both 'do_reset()'

When testing with 'p3400-rebase.sh' and 'p3404-rebase-interactive.sh', the
performance change of this update was negligible, likely due to the
operation being dominated by more expensive operations (like checking out

Add (disabled by default) option to skip the 'cache_tree_update()' at the
end of 'unpack_trees()'. In many cases, this cache tree update is redundant
because the caller of 'unpack_trees()' immediately follows it with
'prime_cache_tree()', rebuilding the entire cache tree from scratch. While
these operations aren't the most expensive part of operations like 'git
reset', the duplicate calls still create a minor unnecessary slowdown.
Introduce an option for callers to skip the 'cache_tree_update()' in

called afterwards). At the moment, no 'unpack_trees()' callers use the new

Add a performance test comparing the execution times of 'prime_cache_tree()'
and 'cache_tree_update(_, WRITE_TREE_SILENT | WRITE_TREE_REPAIR)'. The goal
of comparing these two is to identify which is the faster method for
rebuilding an invalid cache tree, ultimately to remove one when both are
(reundantly) called in immediate succession.
Both methods are fast, so the new tests in 'p0090-cache-tree.sh' must call
each tested function multiple times to ensure the reported times (to 0.01s
resolution) convey the differences between them.
The tests compare the timing of a 'test-tool cache-tree' run as a no-op (to
capture a baseline for the overhead associated with running the tool),
'cache_tree_update()', and 'prime_cache_tree()' on four scenarios:
- A completely valid cache tree
- A cache tree with 2 invalid paths
- A cache tree with 50 invalid paths
- A completely empty cache tree
Example results:
Test this tree
-----------------------------------------------------------
0090.2: no-op, clean 1.27(0.48+0.52)
0090.3: prime_cache_tree, clean 2.02(0.83+0.85)
0090.4: cache_tree_update, clean 1.30(0.49+0.54)
0090.5: no-op, invalidate 2 1.29(0.48+0.54)
0090.6: prime_cache_tree, invalidate 2 1.98(0.81+0.83)
0090.7: cache_tree_update, invalidate 2 2.12(0.94+0.86)

0090.13: cache_tree_update, empty 2.51(1.27+0.92)
These timings show that, while 'cache_tree_update()' is faster when the
cache tree is completely valid, it is equal to or slower than
'prime_cache_tree()' when there are any invalid paths. Since the redundant
calls are mostly in scenarios where the cache tree will be at least
partially invalid (e.g., 'git reset --hard'), 'prime_cache_tree()' will
likely perform better than 'cache_tree_update()' in typical cases.

When deleting a branch, "git branch -d" has a safety check that ensures
the branch is merged to its upstream (if any), or to HEAD. To do that,
naturally we try to resolve HEAD to a commit object. If we're on an
orphan branch (i.e., HEAD points to a branch that does not yet exist),
that will fail, and we'll bail with an error:
$ git branch -d to-delete
fatal: Couldn't look up commit object for HEAD
This usually isn't that big of a deal. The deletion would fail anyway,
since the branch isn't merged to HEAD, and you'd need to use "-D" (or
"-f"). And doing so skips the HEAD resolution, courtesy of 67affd5173
(git-branch -D: make it work even when on a yet-to-be-born branch,
2006-11-24).
But there are still two problems:
1. The error message isn't very helpful. We should give the usual "not
fully merged" message, which points the user at "branch -D". That
was a problem even back in 67affd5173.
2. Even without a HEAD, these days it's still possible for the
deletion to succeed. After 67affd5173, commit 99c419c915 (branch
-d: base the "already-merged" safety on the branch it merges with,
2009-12-29) made it OK to delete a branch if it is merged to its
upstream.
We can fix both by removing the die() in delete_branches() completely,
leaving head_rev NULL in this case. It's tempting to stop there, as it
appears at first glance that the rest of the code does the right thing
with a NULL. But sadly, it's not quite true.
We end up feeding the NULL to repo_is_descendant_of(). In the
traditional code path there, we call repo_in_merge_bases_many(). It
feeds the NULL to repo_parse_commit(), which is smart enough to return
an error, and we immediately return "no, it's not a descendant".
But there's an alternate code path: if we have a commit graph with
generation numbers, we end up in can_all_from_reach(), which does
eventually try to set a flag on the NULL commit and segfaults.
So instead, we'll teach the local branch_merged() helper to treat a NULL
as "not merged". This would be a little more elegant in in_merge_bases()
itself, but that function is called in a lot of places, and it's not
clear that quietly returning "not merged" is the right thing everywhere
(I'd expect in many cases, feeding a NULL is a sign of a bug).
There are four tests here:
a. The first one confirms that deletion succeeds with an orphaned HEAD
when the branch is merged to its upstream. This is case (2) above.
b. Same, but with commit graphs enabled. Even if it is merged to
upstream, we still check head_rev so that we can say "deleting
because it's merged to upstream, even though it's not merged to
HEAD". Without the second hunk in branch_merged(), this test would
segfault in can_all_from_reach().
c. The third one confirms that we correctly say "not merged to HEAD"
when we can't resolve HEAD, and reject the deletion.
d. Same, but with commit graphs enabled. Without the first hunk in
branch_merged(), this one would segfault.

Previously, the example *decreased* the cache timeout compared to the
default, making it less user friendly.
Instead, nudge users to make cache more usable. Many users choose
store over cache.

The default timeout remains 15 minutes. A stronger nudge would
be to increase that.

Now that struct replay_opts has a reflog_action member we no longer
need to export GIT_REFLOG_ACTION when starting a rebase. If the user
has set GIT_REFLOG_ACTION then we use it when initializing
reflog_action.

Each time it picks a commit the sequencer copies the GIT_REFLOG_ACITON
environment variable so it can temporarily change it and then restore
the previous value. This results in code that is hard to follow and also
leaks memory because (i) we fail to free the copy when we've finished
with it and (ii) each call to setenv() leaks the previous value. Instead
pass the reflog action around in a variable and use it to set
GIT_REFLOG_ACTION in the child environment when running "git commit".
Within the sequencer GIT_REFLOG_ACTION is no longer set and is only read
by sequencer_reflog_action(). It is still set by rebase before calling
the sequencer, that will be addressed in the next commit. cherry-pick
and revert are unaffected as they do not set GIT_REFLOG_ACTION before
calling the sequencer.

When t7610-mergetool.sh runs without failures the git://example.com
submodule URLs will never be used. That's because we "git submodule
add" it, but then manually populate them so that subsequent "git
submodule update -N" won't attempt to clone it, only update it without
fetching.
But if we fail in an earlier test it'll have the knock-on effect of
having later tests hang on that "git submodule update -N" as we
attempt to clone this repository from example.com.
This can be reproduced on "master" by running the test with
SANITIZE=leak without "--immediate". With
"GIT_TEST_PASSING_SANITIZE_LEAK=true" (which the linux-leaks job uses)
we'll skip the test entirely. So we'll only run into this when running
it manually, or with the "GIT_TEST_PASSING_SANITIZE_LEAK=check" mode.
That's not because the failure has anything to do with leak detection
per-se. It just so happens that we have a leak that'll fail before
we've managed to fully set these up, and therefore "git submodule
update -N" ends up spawning "git clone".
Let's instead continue lying about the origin of this submodule by
providing a URL for it that doesn't work, but now one that *really*
doesn't work: /dev/null. If the test is passing we won't ever use
this, and if we have knock-on failures we'll fail early, instead of
waiting for a timeout.
The behavior of "-N" here might be surprising to some, since it's
explained as "[if you use -N we] don’t fetch new objects from the
remote site". But (perhaps counter-intuitively) it's only talking
about if it needs to do so via "git fetch". In this case we'll end up
spawning a "git clone", as we have no submodule set up.
See ff7f089ed1 (mergetool: Teach about submodules, 2011-04-13) for
the commit that implemented these "example.com" tests.

Resolves a problem where symbolic links were not showing up in diff when
created or modified.
kFSEventStreamEventFlagItemIsSymlink is also treated as a file update.
This is because kFSEventStreamEventFlagItemIsFile is not included in
FSEvents when creating or deleting symbolic links. For example:
$ ln -snf t test
fsevent: '/path/to/dir/test', flags=0x40100 ItemCreated|ItemIsSymlink|

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.
