Derrick Stolee 0011f94a4f t: avoid "whitelist"
The word "whitelist" has cultural implications that are not inclusive.
Thankfully, it is not difficult to reword and avoid its use.

Focus on changes in the test scripts, since most of the changes are in
comments and test names. The renamed test_allow_var helper is only used
once inside the widely-used test_proto helper.

Derrick Stolee acc5e287f2 git-cvsserver: clarify directory list
The documentation and error messages for git-cvsserver include some
references to a "whitelist" that is not otherwise included in the
documentation. When different parts of the documentation do not use
common language, this can lead to confusion as to how things are meant
to operate.

Further, the word "whitelist" has cultural implications that make its
use non-inclusive. Thankfully, we can remove it while increasing
clarity.

Update Documentation/git-cvsserver.txt in a similar way to the previous
change to Documentation/git-daemon.txt. The optional '<directory>...'
list can specify a list of allowed directories. We refer to that list
directly inside of the documentation for the GIT_CVSSERVER_ROOT
environment variable.

While modifying this documentation, update the environment variables to
use a list format. We use the modern way of tabbing the description of
each variable in this section. We do _not_ update the description of
'<directory>...' to use tabs this way since the rest of the items in the
OPTIONS list do not use this modern formatting.

A single error message in the actual git-cvsserver.perl code refers to
the whitelist during argument parsing. Instead, refer to the directory
list that has been clarified in the documentation.

Manuel Boni 07aed58017 config.txt: document include, includeIf
Git config's tab completion does not yet know about the "include"
and "includeIf" sections, nor the related "path" variable.

Add a description for these two sections in
'Documentation/config/includeif.txt', which points to git-config's
documentation, specifically the "Includes" and "Conditional Includes"
subsections.

As a side effect, tab completion can successfully complete the
'include', 'includeIf', and 'include.add' expressions.
This effect is tested by two new ad-hoc tests.
Variable completion only works for "include" for now.

Credit for the ideas behind this patch goes to

Jeff King cc8fcd1e1a clone: use remote branch if it matches default HEAD
Usually clone tries to use the same local HEAD as the remote (unless the
user has given --branch explicitly). Even if the remote HEAD is detached
or unborn, we can detect those situations with modern versions of Git.
If the remote is too old to support the "unborn" extension (or it has
been disabled via config), then we can't know the name of the remote's
unborn HEAD, and we fall back whatever the local default branch name is
configured to be.

But that leads to one weird corner case. It's rare because it needs a
number of factors:

  - the remote has an unborn HEAD

  - the remote is too old to support "unborn", or has disabled it

  - the remote has another branch "foo"

  - the local default branch name is "foo"

In that case you end up with a local clone on an unborn "foo" branch,
disconnected completely from the remote's "foo". This is rare in
practice, but the result is quite confusing.

When choosing "foo", we can double check whether the remote has such a
name, and if so, start our local "foo" at the same spot, rather than
making it unborn.

Note that this causes a test failure in t5605, which is cloning from a
bundle that doesn't contain HEAD (so it behaves like a remote that
doesn't support "unborn"), but has a single "main" branch. That test
expects that we end up in the weird "unborn main" case, where we don't
actually check out the remote branch of the same name. Even though we
have to update the test, this seems like an argument in favor of this
patch: checking out main is what I'd expect from such a bundle.

So this patch updates the test for the new behavior and adds an adjacent
one that checks what the original was going for: if there's no HEAD and
the bundle _doesn't_ have a branch that matches our local default name,
then we end up with nothing checked out.

Jeff King 3d8314f8d1 clone: propagate empty remote HEAD even with other branches
Unless "--branch" was given, clone generally tries to match the local
HEAD to the remote one. For most repositories, this is easy: the remote
tells us which branch HEAD was pointing to, and we call our local
checkout() function on that branch.

When cloning an empty repository, it's a little more tricky: we have
special code that checks the transport's "unborn" extension, or falls back
to our local idea of what the default branch should be. In either case,
we point the new HEAD to that, and set up the branch.* config.

But that leaves one case unhandled: when the remote repository _isn't_
empty, but its HEAD is unborn. The checkout() function is smart enough
to realize we didn't fetch the remote HEAD and it bails with a warning.
But we'll have ignored any information the remote gave us via the unborn
extension. This leads to nonsense outcomes:

  - If the remote has its HEAD pointing to an unborn "foo" and contains
    another branch "bar", cloning will get branch "bar" but leave the
    local HEAD pointing at "master" (or whatever our local default is),
    which is useless. The project does not use "master" as a branch.

  - Worse, if the other branch "bar" is instead called "master" (but
    again, the remote HEAD is not pointing to it), then we end up with a
    local unborn branch "master", which is not connected to the remote
    "master" (it shares no history, and there's no branch.* config).

Instead, we should try to use the remote's HEAD, even if its unborn, to
be consistent with the other cases.

The reason this case was missed is that cmd_clone() handles empty and
non-empty repositories on two different sides of a conditional:

  if (we have any refs) {
      fetch refs;
      check for --branch;
      otherwise, try to point our head at remote head;
      otherwise, our head is NULL;
  } else {
      check for --branch;
      otherwise, try to use "unborn" extension;
      otherwise, fall back to our default name name;
  }

So the smallest change would be to repeat the "unborn" logic at the end
of the first block. But we can note some other overlaps and
inconsistencies:

  - both sides have to handle --branch (though note that it's always an
    error for the empty repo case, since an empty repo by definition
    does not have a matching branch)

  - the fall back to the default name is much more explicit in the
    empty-repo case. The non-empty case eventually ends up bailing
    from checkout() with a warning, which produces a similar result, but
    fails to set up the branch config we do in the empty case.

So let's pull the HEAD setup out of this conditional entirely. This
de-duplicates some of the code and the result is easy to follow, because
helper functions like find_ref_by_name() do the right thing even in the
empty-repo case (i.e., by returning NULL).

There are two subtleties:

  - for a remote with a detached HEAD, it will advertise an oid for HEAD
    (which we store in our "remote_head" variable), but we won't find a
    matching refname (so our "remote_head_points_at" is NULL). In this
    case we make a local detached HEAD to match. Right now this happens
    implicitly by reaching update_head() with a non-NULL remote_head
    (since we skip all of the unborn-fallback). We'll now need to
    account for it explicitly before doing the fallback.

  - for an empty repo, we issue a warning to the user that they've
    cloned an empty repo. The text of that warning doesn't make sense
    for a non-empty repo with an unborn HEAD, so we'll have to
    differentiate the two cases there. We could just use different text,
    but instead let's allow the code to continue down to checkout(),
    which will issue an appropriate warning, like:

      remote HEAD refers to nonexistent ref, unable to checkout

    Continuing down to checkout() will make it easier to do more fixes
    on top (see below).

Note that this patch fixes the case where the other side reports an
unborn head to us using the protocol extension. It _doesn't_ fix the
case where the other side doesn't tell us, we locally guess "master",
and the other side happens to have a "master" which its HEAD doesn't
point. But it doesn't make anything worse there, and it should actually
make it easier to fix that problem on top.

Elijah Newren 751e165424 merge-ort: fix issue with dual rename and add/add conflict
There is code in both merge-recursive and merge-ort for avoiding doubly
transitive renames (i.e. one side renames directory A/ -> B/, and the
other side renames directory B/ -> C/), because this combination would
otherwise make a mess for new files added to A/ on the first side and
wondering which directory they end up in -- especially if there were
even more renames such as the first side renaming C/ -> D/.  In such
cases, it just turns "off" directory rename detection for the higher
order transitive cases.

The testcases added in t6423 a couple commits ago are slightly different
but similar in principle.  They involve a similar case of paired
renaming but instead of A/ -> B/ and B/ -> C/, the second side renames
a leading directory of B/ to C/.  And both sides add a new file
somewhere under the directory that the other side will rename.  While
the new files added start within different directories and thus could
logically end up within different directories, it is weird for a file
on one side to end up where the other one started and not move along
with it.  So, let's just turn off directory rename detection in this
case as well.

Another way to look at this is that if the source name involved in a
directory rename on one side is the target name of a directory rename
operation for a file from the other side, then we avoid the doubly
transitive rename.  (More concretely, if a directory rename on side D
wants to rename a file on side E from OLD_NAME -> NEW_NAME, and side D
already had a file named NEW_NAME, and a directory rename on side E
wants to rename side D's NEW_NAME -> NEWER_NAME, then we turn off the
directory rename detection for NEW_NAME to prevent the
NEW_NAME -> NEWER_NAME rename, and instead end up with an add/add
conflict on NEW_NAME.)

Elijah Newren 0565cee5e4 t6423: add tests of dual directory rename plus add/add conflict
This is an attempt at minimalizing a testcase reported by Glen Choo
with tensorflow where merge-ort would report an assertion failure:

    Assertion failed: (ci->filemask == 2 || ci->filemask == 4), function apply_directory_rename_modifications, file merge-ort.c, line 2410

reversing the direction of the merge provides a different error:

    error: cache entry has null sha1: ...
    fatal: unable to write .git/index

so we add testcases for both.  With these new testcases, the
recursive strategy differs in that it returns the latter error for
both merge directions.

These testcases are somehow a little different than Glen's original
tensorflow testcase in that these ones trigger a bug with the recursive
algorithm whereas his testcase didn't.  I figure that means these
testcases somehow manage to be more comprehensive.

This test had a line reading

    ! test_file_is_empty actual

which was meant to be

    ! test_must_be_empty actual

The test worked despite the error, because even though
test_file_is_empty is a non-existent function, the '!' negated the
return value and made it pass.  It'd be better to avoid the negation,
so something like

    test_file_not_empty actual

would be better, but perhaps it makes even more sense to specify the
number of lines of expected output to make the test a bit tighter.

Ævar Arnfjörð Bjarmason eb1cd60290 config tests: fix harmless but broken "rm -r" cleanup
The "test_when_finished" cleanup phase added in 4179b4897f (config:
allow overriding of global and system configuration, 2021-04-19) has
never worked as intended, firstly the ".config/git" is a directory, so
we'd need the "-r" flag, but more importantly the $HOME variable
wasn't properly quoted.

We'd thus end up trying to remove the "trash" part of "trash
directory", which wouldn't fail with "-f", since "rm -f" won't fail on
non-existing files.

It's possible that this would have caused an actual failure if someone
had a $HOME with a space character in it, such that our "rm -f" would
fail to remove an existing directory, but in practice that probably
never happened.

Let's fix both the quoting issue, and the other issue cleanup issue in
4179b4897f, which is that we were attempting to clean up
~/.config/git, but weren't cleaing up ~/.gitconfig.

Goss Geppert 27128996b8 dir: traverse into repository
Since 8d92fb2927 (dir: replace exponential algorithm with a linear one,
2020-04-01) traversing into a repository's directory tree when the
traversal began outside the repository's standard location has failed
because the encountered repository was identified as a nested foreign
repository.

Prior to this commit, the failure to traverse into a repository's
default worktree location was observable from a user's perspective under
either of the following conditions (there may be others):

    1) Set the `core.worktree` location to a parent directory of the
       default worktree; or
    2) Use the `--git_dir` option while the working directory is outside
       the repository's default worktree location

Under either of these conditions, symptoms of the failure to traverse
into the repository's default worktree location include the inability to
add files to the index or get a list of untracked files via ls-files.

This commit adds a check to determine whether a nested repository that
is encountered in recursing a path is actually `the_repository`.  If so,
we simply treat the directory as if it doesn't contain a nested
repository.

The commit includes test-cases to reduce the likelihood of future
regressions.

Derrick Stolee 2ffb7d13ee t5510: replace 'origin' with URL more carefully
The many test_configured_prune tests in t5510-fetch.sh test many
combinations of --prune, --prune-tags, and using 'origin' or an explicit
URL. Some machinery was introduced in e1790f9245 (fetch tests: fetch
<url> <spec> as well as fetch [<remote>], 2018-02-09) to replace
'origin' with this explicit URL. This URL is a "file:///" URL for the
root of the $TRASH_DIRECTORY.

However, if the current build tree has an '@' symbol, the
replacement using perl fails. It drops the '@' as well as anything
else in that directory name.  You can observe this locally by
cloning git.git into a "victim@03" directory and running the test
script.

As we are writing in Perl anyway, pass in the shell variables involved
to the script as arguments and perform necessary string transformations
inside it, instead of assuming that it is sufficient to enclose the
$remote_url variable inside a pair of single quotes.

Carlo Marcelo Arenas Belón 6b11e3d52e git-compat-util: allow root to access both SUDO_UID and root owned
Previous changes introduced a regression which will prevent root for
accessing repositories owned by thyself if using sudo because SUDO_UID
takes precedence.

Loosen that restriction by allowing root to access repositories owned
by both uid by default and without having to add a safe.directory
exception.

A previous workaround that was documented in the tests is no longer
needed so it has been removed together with its specially crafted
prerequisite.

Jeff King f8535596aa bug_fl(): correctly initialize trace2 va_list
The code added 0cc05b044f (usage.c: add a non-fatal bug() function to go
with BUG(), 2022-06-02) sets up two va_list variables: one to output to
stderr, and one to trace2. But the order of initialization is wrong:

  va_list ap, cp;
  va_copy(cp, ap);
  va_start(ap, fmt);

We copy the contents of "ap" into "cp" before it is initialized, meaning
it is full of garbage. The two should be swapped.

However, there's another bug, noticed by Johannes Schindelin: we forget
to call va_end() for the copy. So instead of just fixing the copy's
initialization, let's do two separate start/end pairs. This is allowed
by the standard, and we don't need to use copy here since we have access
to the original varargs. Matching the pairs with the calls makes it more
obvious that everything is being done correctly.

Note that we do call bug_fl() in the tests, but it didn't trigger this
problem because our format string doesn't have any placeholders. So even
though we were passing a garbage va_list through the stack, nobody ever
needed to look at it. We can easily adjust one of the trace2 tests to
trigger this, both for bug() and for BUG(). The latter isn't broken, but
it's nice to exercise both a bit more. Without the fix in this patch
(but with the test change), the bug() case causes a segfault.

Jeff King 55d9d4bbd0 perf-lib: fix missing test titles in output
Commit 5dccd9155f (t/perf: add iteration setup mechanism to perf-lib,
2022-04-04) modified the parameter parsing of test_wrapper() such that
the test title was no longer in $1, and is instead in $test_title_.

We correctly pass the new variable to the code which outputs the title
to the log, but missed the spot in test_wrapper() where the title is
written to the ".descr" file which is used to produce the final output
table. As a result, all of the titles are missing from that table (or
worse, using whatever was left in $1):

Ævar Arnfjörð Bjarmason 7596fe952d tests: add LIBCURL prerequisite to tests needing libcurl
Add and use a LIBCURL prerequisite for tests added in
6dcbdc0d66 (remote: create fetch.credentialsInUrl config,
2022-06-06).

These tests would get as far as emitting a couple of the warnings we
were testing for, but would then die as we had no "git-remote-https"
program compiled.

It would be more consistent with other prerequisites (e.g. PERL for
NO_PERL) to name this "CURL", but since e9184b0789 (t5561: skip tests
if curl is not available, 2018-04-03) we've had that prerequisite
defined for checking of we have the curl(1) program.

The existing "CURL" prerequisite is only used in one place, and we
should probably name it "CURL_PROGRAM", then rename "LIBCURL" to
"CURL" as a follow-up, but for now (pre-v2.37.0) let's aim for the
most minimal fix possible.

Ævar Arnfjörð Bjarmason 7281c196b1 transfer doc: move fetch.credentialsInUrl to "transfer" config namespace
Rename the "fetch.credentialsInUrl" configuration variable introduced
in 6dcbdc0d66 (remote: create fetch.credentialsInUrl config,
2022-06-06) to "transfer".

There are existing exceptions, but generally speaking the
"<namespace>.<var>" configuration should only apply to command
described in the "namespace" (and its sub-commands, so e.g. "clone.*"
or "fetch.*" might also configure "git-remote-https").

But in the case of "fetch.credentialsInUrl" we've got a configuration
variable that configures the behavior of all of "clone", "push" and
"fetch", someone adjusting "fetch.*" configuration won't expect to
have the behavior of "git push" altered, especially as we have the
pre-existing "{transfer,fetch,receive}.fsckObjects", which configures
different parts of the transfer dialog.

So let's move this configuration variable to the "transfer" namespace
before it's exposed in a release. We could add all of
"{transfer,fetch,pull}.credentialsInUrl" at some other time, but once
we have "fetch" configure "pull" such an arrangement would would be a
confusing mess, as we'd at least need to have "fetch" configure
"push" (but not the other way around), or change existing behavior.

Ævar Arnfjörð Bjarmason 7ccbea564e add -i tests: mark "TODO" depending on GIT_TEST_ADD_I_USE_BUILTIN
Fix an issue that existed before 0527ccb1b5 (add -i: default to the
built-in implementation, 2021-11-30), but which became the default
with that change, we should not be marking tests that are known to
pass as "TODO" tests.

When GIT_TEST_ADD_I_USE_BUILTIN=1 was made the default we started
passing the tests added in 0f0fba2cc8 (t3701: add a test for advanced
split-hunk editing, 2019-12-06) and 1bf01040f0 (add -p: demonstrate
failure when running 'edit' after a split, 2015-04-16).

Thus we've been emitting this sort of output:

	$ prove ./t3701-add-interactive.sh
	./t3701-add-interactive.sh .. ok
	All tests successful.

	Test Summary Report
	-------------------
	./t3701-add-interactive.sh (Wstat: 0 Tests: 70 Failed: 0)
	  TODO passed:   45, 47
	Files=1, Tests=70,  2 wallclock secs ( 0.03 usr  0.00 sys +  0.86 cusr  0.33 csys =  1.22 CPU)
	Result: PASS

Which isn't just cosmetic, but due to issues with
test_expect_failure (see [1]) we could e.g. be hiding something as bad
as a segfault in the new implementation. It makes sense catch that,
especially before we put out a release with the built-in "add -i", so
let's generalize the check we were already doing in 0527ccb1b5 with a
new "ADD_I_USE_BUILTIN" prerequisite.
