%(rest) is a atom used for cat-file batch mode, which can split
the input lines at the first whitespace boundary, all characters
before that whitespace are considered to be the object name;
characters after that first run of whitespace (i.e., the "rest"
of the line) are output in place of the %(rest) atom.
In order to let "cat-file --batch=%(rest)" use the ref-filter
interface, add %(rest) atom for ref-filter.
Introduce the reject_atom() to reject the atom %(rest) for
"git for-each-ref", "git branch", "git tag" and "git verify-tag".

Because the perl language can handle binary data correctly,
add the function perl_quote_buf_with_len(), which can specify
the length of the data and prevent the data from being truncated
at '\0' to help `--format="%(raw)"` support `--perl`.

Add new formatting option `%(raw)`, which will print the raw
object data without any changes. It will help further to migrate
all cat-file formatting logic from cat-file to ref-filter.
The raw data of blob, tree objects may contain '\0', but most of
the logic in `ref-filter` depends on the output of the atom being
text (specifically, no embedded NULs in it).
E.g. `quote_formatting()` use `strbuf_addstr()` or `*._quote_buf()`
add the data to the buffer. The raw data of a tree object is
`100644 one\0...`, only the `100644 one` will be added to the buffer,
which is incorrect.
Therefore, we need to find a way to record the length of the
atom_value's member `s`. Although strbuf can already record the
string and its length, if we want to replace the type of atom_value's
member `s` with strbuf, many places in ref-filter that are filled
with dynamically allocated mermory in `v->s` are not easy to replace.
At the same time, we need to check if `v->s == NULL` in
populate_value(), and strbuf cannot easily distinguish NULL and empty
strings, but c-style "const char *" can do it. So add a new member in
`struct atom_value`: `s_size`, which can record raw object size, it
can help us add raw object data to the buffer or compare two buffers
which contain raw object data.
Note that `--format=%(raw)` cannot be used with `--python`, `--shell`,
`--tcl`, and `--perl` because if the binary raw data is passed to a
variable in such languages, these may not support arbitrary binary data
in their string variable type.

Dash bug https://bugs.launchpad.net/ubuntu/+source/dash/+bug/139097
lets the shell erroneously perform field splitting on the expansion of a
command substitution during declaration of a local variable. It causes
the parallel-checkout tests to fail e.g. when running them with
/bin/dash on MacOS 11.4, where they error out like this:
./t2080-parallel-checkout-basics.sh: 33: local: 0: bad variable name
That's because the output of wc -l contains leading spaces and the
returned number of lines is treated as another variable to declare, i.e.
as in "local workers= 0".
Work around it by enclosing the command substitution in quotes.

The --batch code to print an object assumes we found out the type of
the object from calling oid_object_info_extended(). This is true for
the default format, but even in a custom format, we manually modify
the object_info struct to ask for the type.
This assumption was broken by 845de33a5b (cat-file: avoid noop calls
to sha1_object_info_extended, 2016-05-18). That commit skips the call
to oid_object_info_extended() entirely when --batch-all-objects is in
use, and the custom format does not include any placeholders that
require calling it.
Or when the custom format only include placeholders like %(objectname) or
%(rest), oid_object_info_extended() will not get the type of the object.
This results in an error when we try to confirm that the type didn't
change:
$ git cat-file --batch=batman --batch-all-objects
batman
fatal: object 000023961a0c02d6e21dc51ea3484ff71abf1c74 changed type!?
and also has other subtle effects (e.g., we'd fail to stream a blob,
since we don't realize it's a blob in the first place).
We can fix this by flipping the order of the setup. The check for "do
we need to get the object info" must come _after_ we've decided
whether we need to look up the type.

t2080 makes a few copies of a test repository and later performs a
branch switch on each one of the copies to verify that parallel checkout
and sequential checkout produce the same results. However, the
repository is copied with `cp -R` which, on some systems, defaults to
following symlinks on the directory hierarchy and copying their target
files instead of copying the symlinks themselves. AIX is one example of
system where this happens. Because the symlinks are not preserved, the
copied repositories have paths that do not match what is in the index,
causing git to abort the checkout operation that we want to test. This
makes the test fail on these systems.
Fix this by copying the repository with the POSIX flag '-P', which
forces cp to copy the symlinks instead of following them. Note that we
already use this flag for other cp invocations in our test suite (see
t7001). With this change, t2080 now passes on AIX.

In c8243933c74 (git-send-email: Respect core.hooksPath setting,
2021-03-23) we started supporting core.hooksPath in "send-email". It's
been reported that on Windows[1] doing this by calling abs_path()
results in different canonicalizations of the absolute path.
This wasn't an issue in c8243933c74 itself, but was revealed by my
ea7811b37e0 (git-send-email: improve --validate error output,
2021-04-06) when we started emitting the path to the hook, which was
previously only internal to git-send-email.perl.
The just-landed 53753a37d09 (t9001-send-email.sh: fix expected
absolute paths on Windows, 2021-05-24) narrowly fixed this issue, but
I believe we can do better here. We should not be relying on whatever
changes Perl's abs_path() makes to the path "rev-parse --git-path
hooks" hands to us. Let's instead trust it, and hand it to Perl's
system() in git-send-email.perl. It will handle either a relative or
absolute path.
So let's revert most of 53753a37d09 and just have "hooks_path" return
what we get from "rev-parse" directly without modification. This has
the added benefit of making the error message friendlier in the common
case, we'll no longer print an absolute path for repository-local hook
errors.

The t1092-sparse-checkout-compatibility.sh tests compare the stdout and
stderr for several Git commands across both full checkouts, sparse
checkouts with a full index, and sparse checkouts with a sparse index.
Since these are direct comparisons, sometimes a progress indicator can
flush at unpredictable points, especially on slower machines. This
causes the tests to be flaky.
One standard way to avoid this is to add GIT_PROGRESS_DELAY=0 to the Git
commands that are run, as this will force every progress indicator
created with start_progress_delay() to be created immediately. However,
there are some progress indicators that are created in the case of a
full index that are not created with a sparse index. Moreover, their
values may be different as those indexes have a different number of
entries.
Instead, use GIT_PROGRESS_DELAY=-1 (which will turn into UINT_MAX)
to ensure that any reasonable machine running these tests would
never display delayed progress indicators.

We used to read the init.templateDir setting at builtin/init-db.c using
a git_config() callback that, in turn, called git_config_pathname(). To
simplify the config reading logic at this file and plug a memory leak,
this was replaced by a direct call to git_config_get_value() at
e4de4502e6 ("init: remove git_init_db_config() while fixing leaks",
2021-03-14). However, this function doesn't provide path expanding
semantics, like git_config_pathname() does, so paths with '~/' and
'~user/' are treated literally. This makes 'git init' fail to handle
init.templateDir paths using these constructs:
$ git config init.templateDir '~/templates_dir'
$ git init
'warning: templates not found in ~/templates_dir'
Replace the git_config_get_value() call by git_config_get_pathname(),
which does the '~/' and '~user/' expansions. Also add a regression test.
Note that unlike git_config_get_value(), the config cache does not own
the memory for the path returned by git_config_get_pathname(), so we
must free() it.

Git for Windows is a native Windows program that works with native
absolute paths in the drive letter style C:\dir. The auxiliary
infrastructure is based on MSYS2, which uses POSIX style /C/dir.
When we test for output of absolute paths produced by git.exe, we
usally have to expect C:\dir style paths. To produce such expected
paths, we have to use $(pwd) in the test scripts; the alternative,
$PWD, produces a POSIX style path. ($PWD is a shell variable, and the
shell is bash, an MSYS2 program, and operates in the POSIX realm.)
There are two recently added tests that were written to expect C:\dir
paths. The output that is tested is produced by `git send-email`, but
behind the scenes, this is a Perl script, which also works in the
POSIX realm and produces /C/dir style output.
In the first test case that is changed here, replace $(pwd) by $PWD
so that the expected path is constructed using /C/dir style.
The second test case sets core.hooksPath to an absolute path. Since
the test script talks to native git.exe, it is supposed to place a
C:/dir style path into the configuration; therefore, keep $(pwd).
When this configuration value is consumed by the Perl script, it is
transformed to /C/dir style by the MSYS2 layer and echoed back in
this form in the error message. Hence, do use $PWD for the expected
value.

If options pertaining to how the diff is displayed is provided to
`git stash show`, the command will ignore the stash.showIncludeUntracked
configuration variable, defaulting to not showing any untracked files.
This is unintuitive behaviour since the format of the diff output and
whether or not to display untracked files are orthogonal.
Use stash.showIncludeUntracked even when diff options are given. Of
course, this is still overridable via the command-line options.

will be overridden when a diff options are given.

Fix long standing inconsistency between -c/--cc that do imply -p on
one side, and -m that did not imply -p on the other side.
Change corresponding test accordingly, as "log -m" output should now
match one from "log -m -p", rather than from just "log".
Change documentation accordingly.
NOTES:
After this patch
git log -m
produces diffs without need to provide -p as well, that improves both
consistency and usability. It gets even more useful if one sets
"log.diffMerges" configuration variable to "first-parent" to force -m
produce usual diff with respect to first parent only.
This patch, however, does not change behavior when specific diff
format is explicitly provided on the command-line, so that commands
like
git log -m --raw
git log -m --stat
are not affected, nor does it change commands where specific diff
format is active by default, such as:
git diff-tree -m
It's also worth to be noticed that exact historical semantics of -m is

When there are many renames between the old base of a series of commits
and the new base, the way sequencer.c, merge-recursive.c, and
diffcore-rename.c have traditionally split the work resulted in
redetecting the same renames with each and every commit being
transplanted. To address this, the last several commits have been
creating a cache of rename detection results, determining when it was
safe to use such a cache in subsequent merge operations, adding helper
functions, and so on. See the previous half dozen commit messages for
additional discussion of this optimization, particularly the message a
few commits ago entitled "add code to check for whether cached renames
can be reused". This commit finally ties all of that work together,
modifying the merge algorithm to make use of these cached renames.
For the testcases mentioned in commit 557ac0350d ("merge-ort: begin
performance work; instrument with trace2_region_* calls", 2020-10-28),
this change improves the performance as follows:
Before After
no-renames: 5.665 s ± 0.129 s 5.622 s ± 0.059 s
mega-renames: 11.435 s ± 0.158 s 10.127 s ± 0.073 s
just-one-mega: 494.2 ms ± 6.1 ms 500.3 ms ± 3.8 ms
That's a fairly small improvement, but mostly because the previous
optimizations were so effective for these particular testcases; this
optimization only kicks in when the others don't. If we undid the
basename-guided rename detection and skip-irrelevant-renames
optimizations, then we'd see that this series by itself improved
performance as follows:
Before Basename Series After Just This Series
no-renames: 13.815 s ± 0.062 s 5.697 s ± 0.080 s
mega-renames: 1799.937 s ± 0.493 s 205.709 s ± 0.457 s
Since this optimization kicks in to help accelerate cases where the
previous optimizations do not apply, this last comparison shows that
this cached-renames optimization has the potential to help signficantly
in cases that don't meet the requirements for the other optimizations to
be effective.
The changes made in this optimization also lay some important groundwork
for a future optimization around having collect_merge_info() avoid
recursing into subtrees in more cases.
However, for this optimization to be effective, merge_switch_to_result()
should only be called when the rebase or cherry-pick operation has
either completed or hit a case where the user needs to resolve a
conflict or edit the result. If it is called after every commit, as
sequencer.c does, then the working tree and index are needlessly updated
with every commit and the cached metadata is tossed, defeating this
optimization. Refactoring sequencer.c to only call
merge_switch_to_result() at the end of the operation is a bigger
undertaking, and the practical benefits of this optimization will not be
realized until that work is performed. Since `test-tool fast-rebase`
only updates at the end of the operation, it was used to obtain the
timings above.

We will soon be adding an optimization that caches (in memory only,
never written to disk) upstream renames during a sequence of merges such
as occurs during a cherry-pick or rebase operation. Add several tests
meant to stress such an implementation to ensure it does the right
thing, and include a test whose outcome we will later change due to this
optimization as well.

Previously, when fast-rebase hit a conflict, it simply aborted and left
HEAD, the index, and the working tree where they were before the
operation started. While fast-rebase does not support restarting from a
conflicted state, write the conflicted state out anyway as it gives us a
way to see what the conflicts are and write tests that check for them.
This will be important in the upcoming commits, because sequencer.c is
only superficially integrated with merge-ort.c; in particular, it calls
merge_switch_to_result() after EACH merge instead of only calling it at
the end of all the sequence of merges (or when a conflict is hit). This
not only causes needless updates to the working copy and index, but also
causes all intermediate data to be freed and tossed, preventing caching
information from one merge to the next. However, integrating
sequencer.c more deeply with merge-ort.c is a big task, and making this
small extension to fast-rebase.c provides us with a simple way to test
the edge and corner cases that we want to make sure continue working.

assert() can succinctly document expectations for the code, and do so in
a way that may be useful to future folks trying to refactor the code and
change basic assumptions; it allows them to more quickly find some
places where their violations of previous assumptions trips things up.
Unfortunately, assert() can surround a function call with important
side-effects, which is a huge mistake since some users will compile with
assertions disabled. I've had to debug such mistakes before in other
codebases, so I should know better. Luckily, this was only in test

The "chainlint" feature in the test framework is a handy way to
catch common mistakes in writing new tests, but tends to get
expensive. An knob to selectively disable it has been introduced
to help running tests that the developer has not modified.
* jk/test-chainlint-softer:
t: avoid sed-based chain-linting in some expensive cases

The handling of "%(push)" formatting element of "for-each-ref" and
friends was broken when the same codepath started handling
"%(push:<what>)", which has been corrected.
* zh/ref-filter-push-remote-fix:
ref-filter: fix read invalid union member bug

"git clean" and "git ls-files -i" had confusion around working on
or showing ignored paths inside an ignored directory, which has
been corrected.
* en/dir-traversal:
dir: introduce readdir_skip_dot_and_dotdot() helper
dir: update stale description of treat_directory()
dir: traverse into untracked directories if they may have ignored subfiles
dir: avoid unnecessary traversal into ignored directory
t3001, t7300: add testcase showcasing missed directory traversal
t7300: add testcase showing unnecessary traversal into ignored directory
ls-files: error out on -i unless -o or -c are specified
dir: report number of visited directories and paths with trace2
dir: convert trace calls to trace2 equivalents

git-clone started respecting errors from the transport subsystem in
aab179d937 (builtin/clone.c: don't ignore transport_fetch_refs() errors,
2020-12-03). However, that commit didn't handle the cleanup of the
filesystem quite right.
The cleanup of the directory that cmd_clone() creates is done by an
atexit() handler, which we control with a flag. It starts as
JUNK_LEAVE_NONE ("clean up everything"), then progresses to
JUNK_LEAVE_REPO when we know we have a valid repo but not working tree,
and then finally JUNK_LEAVE_ALL when we have a successful checkout.
Most errors cause us to die(), which then triggers the handler to do the
right thing based on how far into cmd_clone() we got. But the checks
added by aab179d937 instead set the "err" variable and then jump to a
new "cleanup" label, which then returns our non-zero status. However,
the code after the cleanup label includes setting the flag to
JUNK_LEAVE_ALL, and so we accidentally leave the repository and working
tree in place.
One obvious option to fix this is to reorder the end of the function to
set the flag first, before cleanup code, and put the label between them.
But we can observe another small bug: the error return from
transport_fetch_refs() is generally "-1", and we propagate that to the
return value of cmd_clone(), which ultimately becomes the exit code of
the process. And we try to avoid transmitting negative values via exit
codes (only the low 8 bits are passed along as an unsigned value, though
in practice for "-1" this at least retains the property that it's
non-zero).
Instead, let's just die(). That makes us consistent with rest of the
code in the function. It does add a new "fatal:" line to the output, but
I'd argue that's a good thing:
- in the rare case that the transport code didn't say anything, now
the user gets _some_ error message
- even if the transport code said something like "error: ssh died of
signal 9", it's nice to also say "fatal" to indicate that we
considered that to be a show-stopper.
Triggering this in the test suite turns out to be surprisingly
difficult. Almost every error we'd encounter, including ones deep inside
the transport code, cause us to just die() right there! However, one way
is to put a fake wrapper around git-upload-pack that sends the complete
packfile but exits with a failure code.

This reverts commit 1b0d9545bb85912a16b367229d414f55d140d3be.
That commit does fix the situation it intended to (avoiding Negotiate
even when the credentials were provided in the URL), but it creates a
more serious regression: we now never hit the conditional for "we had a
username and password, tried them, but the server still gave us a 401".
That has two bad effects:
1. we never call credential_reject(), and thus a bogus credential
stored by a helper will live on forever
2. we never return HTTP_NOAUTH, so the error message the user gets is
"The requested URL returned error: 401", instead of "Authentication
failed".
Doing this correctly seems non-trivial, as we don't know whether the
Negotiate auth was a problem. Since this is a regression in the upcoming
v2.23.0 release (for which we're in -rc0), let's revert for now and work
on a fix separately.
(Note that this isn't a pure revert; the previous commit added a test
showing the regression, so we can now flip it to expect_success).

We test authentication with http, and we independently test that
credential helpers work, but we don't have any tests that cover the
two features working together. Let's add two:
1. Make sure that a successful request asks the helper to save the
credential. This works as expected.
2. Make sure that a failed request asks the helper to forget the
credential. This is marked as expect_failure, as it was recently
regressed by 1b0d9545bb (remote-curl: fall back to basic auth if
Negotiate fails, 2021-03-22). The symptom here is that the second
request should prompt the user, but doesn't.

The C_LOCALE_OUTPUT prerequisite was removed in b1e079807b (tests:
remove last uses of C_LOCALE_OUTPUT, 2021-02-11), where Ævar noted:
I'm not leaving the prerequisite itself in place for in-flight changes
as there currently are none that introduce new tests that rely on it,
and because C_LOCALE_OUTPUT is currently a noop on the master branch
we likely won't have any new submissions that use it.
One more use of C_LOCALE_OUTPUT did creep in with 3d1bda6b5b (t7500: add
tests for --fixup=[amend|reword] options, 2021-03-15). This causes a
number of the tests to be skipped by default:
ok 35 # SKIP --fixup=reword: incompatible with --all (missing C_LOCALE_OUTPUT)
ok 36 # SKIP --fixup=reword: incompatible with --include (missing C_LOCALE_OUTPUT)
ok 37 # SKIP --fixup=reword: incompatible with --only (missing C_LOCALE_OUTPUT)
ok 38 # SKIP --fixup=reword: incompatible with --interactive (missing C_LOCALE_OUTPUT)
ok 39 # SKIP --fixup=reword: incompatible with --patch (missing C_LOCALE_OUTPUT)
Remove the C_LOCALE_OUTPUT prerequisite from these tests so they are
not skipped.
