When the TEST_OUTPUT_DIRECTORY is defined, then all test data will be
written in that directory instead of the default directory located in
"t/". While this works as expected for our normal tests, performance
tests fail to locate and aggregate performance data because they don't
know to handle TEST_OUTPUT_DIRECTORY correctly and always look at the
default location.
Fix the issue by adding a `--results-dir` parameter to "aggregate.perl"
which identifies the directory where results are and by making the "run"
script awake of the TEST_OUTPUT_DIRECTORY variable.

parallel-checkout: avoid dash local bug in tests
|
|
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.

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.
Update the documentation to explicitly say which configuration variables
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
still provided by --diff-merges=separate.

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.

Unfortunately, assert() can surround a function call with important

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).

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.

Calling "git rev-parse --path-format" without an argument segfaults
instead of giving an error message. Commit fac60b8925 (rev-parse: add
option for absolute or relative path formatting, 2020-12-13) added the
argument parsing code but forgot to handle NULL.
Returning an error makes sense here because there is no default value we
could use. Add a test case to verify.

The sendemail.smtpServer configuration option and --smtp-server command
line option both support using a sendmail-like program to send emails by
specifying an absolute file path. However, this is not ideal for the
following reasons:
1. It overloads the meaning of smtpServer (now a program is being used
for the server?)
2. It doesn't allow for non-absolute paths, arguments, or arbitrary
scripting
Requiring an absolute path is bad for portability, as the same program
may be in different locations on different systems. If a user wishes to
pass arguments to their program, they have to use the smtpServerOption
option, which is cumbersome (as it must be repeated for each option) and
doesn't adhere to normal git conventions.
Introduce a new configuration option sendemail.sendmailCmd as well as a
command line option --sendmail-cmd that can be used to specify a command
(with or without arguments) or shell expression to run to send email.
The name of this option is consistent with --to-cmd and --cc-cmd. This
invocation honors the user's $PATH so that absolute paths are not
necessary. Arbitrary shell expressions are also supported, allowing
users to do basic scripting.
Give this option a higher precedence over --smtp-server and
sendemail.smtpServer, as the new interface is more flexible. For
backward compatibility, continue to support absolute paths in
--smtp-server and sendemail.smtpServer.

Commit 878f988350 (t/test-lib: teach --chain-lint to detect broken
&&-chains in subshells, 2018-07-11) introduced additional chain-lint
tests which add an extra "sed" pipeline to each test we run. This has a
measurable impact on runtime. Here are timings with and without a new
environment variable (added by this patch) that lets you disable just
the additional sed-based chain-lint tests:
Benchmark #1: GIT_TEST_CHAIN_LINT_HARDER=1 make test
Time (mean ± σ): 64.202 s ± 1.030 s [User: 622.469 s, System: 301.402 s]
Range (min … max): 61.571 s … 65.662 s 10 runs
Benchmark #2: GIT_TEST_CHAIN_LINT_HARDER=0 make test
Time (mean ± σ): 57.591 s ± 0.333 s [User: 529.368 s, System: 270.618 s]
Range (min … max): 57.143 s … 58.309 s 10 runs
Summary
'GIT_TEST_CHAIN_LINT_HARDER=0 make test' ran
1.11 ± 0.02 times faster than 'GIT_TEST_CHAIN_LINT_HARDER=1 make test'
Of course those extra lint checks are doing something useful, so paying
a few extra seconds (at least on Linux) isn't so bad (though note the
CPU time; we're bounded in our parallel run here by the slowest test, so
it really is ~120s of CPU improvement).
But we can observe that there are some test scripts where they produce a
much stronger effect, and provide less value. In t0027 and t3070 we run
a very large number of small tests, all driven by a series of
functions/loops which are filling in the test bodies. There we get much
less bang for our buck in terms of bug-finding versus CPU cost.
This patch introduces a mechanism for controlling when those extra
lint checks are run, at two levels:
- a user can ask to disable or to force-enable the checks by setting
GIT_TEST_CHAIN_LINT_HARDER
- if the user hasn't specified a preference, individual scripts can
disable the checks by setting GIT_TEST_CHAIN_LINT_HARDER_DEFAULT;
scripts which don't set that get the current behavior of enabling
them.
In addition, this patch flips the default for t0027 and t3070's
mass-generated sections to disable the extra checks. Here are the timing
results for t0027:
Benchmark #1: GIT_TEST_CHAIN_LINT_HARDER=1 ./t0027-auto-crlf.sh
Time (mean ± σ): 17.078 s ± 0.848 s [User: 14.878 s, System: 7.075 s]
Range (min … max): 15.952 s … 18.421 s 10 runs
Benchmark #2: GIT_TEST_CHAIN_LINT_HARDER=0 ./t0027-auto-crlf.sh
Time (mean ± σ): 9.063 s ± 0.759 s [User: 7.890 s, System: 3.362 s]
Range (min … max): 7.747 s … 10.619 s 10 runs
Benchmark #3: ./t0027-auto-crlf.sh
Time (mean ± σ): 9.186 s ± 0.881 s [User: 7.957 s, System: 3.427 s]
Range (min … max): 7.796 s … 10.498 s 10 runs
Summary
'GIT_TEST_CHAIN_LINT_HARDER=0 ./t0027-auto-crlf.sh' ran
1.01 ± 0.13 times faster than './t0027-auto-crlf.sh'
1.88 ± 0.18 times faster than 'GIT_TEST_CHAIN_LINT_HARDER=1 ./t0027-auto-crlf.sh'
We can see that disabling the checks for the whole script buys us an
almost 2x speedup. But the new default behavior, disabling them only for
the mass-generated part, gets us most of that speedup (but still leaves
the checks on for further manual tests people might write).
As a side note, I'd caution about comparing runtimes and CPU seconds
between this timing and the earlier "make test" one. In "make test",
we're running a lot of scripts in parallel, so the CPU is throttling
down (and thus a CPU second saved here would count for more during a
parallel run; the same work takes more CPU seconds there).
We get similar results for t3070:
Benchmark #1: GIT_TEST_CHAIN_LINT_HARDER=1 ./t3070-wildmatch.sh
Time (mean ± σ): 20.054 s ± 3.967 s [User: 16.003 s, System: 8.286 s]
Range (min … max): 11.891 s … 23.671 s 10 runs
Benchmark #2: GIT_TEST_CHAIN_LINT_HARDER=0 ./t3070-wildmatch.sh
Time (mean ± σ): 12.399 s ± 2.256 s [User: 7.542 s, System: 5.342 s]
Range (min … max): 9.606 s … 15.727 s 10 runs
Benchmark #3: ./t3070-wildmatch.sh
Time (mean ± σ): 10.726 s ± 3.476 s [User: 6.790 s, System: 4.365 s]
Range (min … max): 5.444 s … 15.376 s 10 runs
Summary
'./t3070-wildmatch.sh' ran
1.16 ± 0.43 times faster than 'GIT_TEST_CHAIN_LINT_HARDER=0 ./t3070-wildmatch.sh'
1.87 ± 0.71 times faster than 'GIT_TEST_CHAIN_LINT_HARDER=1 ./t3070-wildmatch.sh'
Again, we get almost a 2x speedup disabling these. In this case, there
are no tests not covered by the script's "default to disable" behavior,
so the second two benchmarks should be the same (and while they do
differ, you can see the variance is quite high but they're within one
standard deviation).
So it seems like for these two scripts, at least, disabling the extra
checks is a reasonable tradeoff. Sadly, the overall runtime of "make
test" on my system doesn't get much faster. But that's because we're
mostly limited by the cost of the single biggest test. Here are the
top-5 tests by wall-clock time from a parallel run, before my patch:
57.9192368984222 t9001-send-email.sh
45.6329638957977 t0027-auto-crlf.sh
32.5278220176697 t3070-wildmatch.sh
22.2701289653778 t7610-mergetool.sh
20.8635759353638 t1701-racy-split-index.sh
And after:
57.1476998329163 t9001-send-email.sh
33.776211977005 t0027-auto-crlf.sh
21.3116669654846 t7610-mergetool.sh
20.7748689651489 t1701-racy-split-index.sh
19.6957249641418 t7112-reset-submodule.sh
We dropped 12s from t0027, and t3070 dropped off our list entirely at
around 16s. In both cases we're bound by t9001, but its slowness is
due to the actual tests, so we'll have to deal with it in a different
way. But this reduces overall CPU, and means that dealing with t9001 (by
improving the speed of send-email or splitting it apart) will let us
reduce our overall runtime even on multi-core machines.

A directory that is untracked does not imply that all files under it
should be categorized as untracked; in particular, if the caller is
interested in ignored files, many files or directories underneath the
untracked directory may be ignored. We previously partially handled
this right with DIR_SHOW_IGNORED_TOO, but missed DIR_SHOW_IGNORED. It
was not obvious, though, because the logic for untracked and excluded
files had been fused together making it harder to reason about. The
previous commit split that logic out, making it easier to notice that
DIR_SHOW_IGNORED was missing. Add it.

The show_other_directories case in treat_directory() tried to handle
both excludes and untracked files with the same logic, and mishandled
both the excludes and the untracked files in the process, in different
ways. Split that logic apart, and then focus on the logic for the
excludes; a subsequent commit will address the logic for untracked
files.
For show_other_directories, an excluded directory means that
every path underneath that directory will also be excluded. Given that
the calling code requested to just show directories when everything
under a directory had the same state (that's what the
"DIR_SHOW_OTHER_DIRECTORIES" flag means), we generally do not need to
traverse into such directories and can just immediately mark them as
ignored (i.e. as path_excluded). The only reason we cannot just
immediately return path_excluded is the DIR_HIDE_EMPTY_DIRECTORIES flag
and the possibility that the ignored directory is an empty directory.
The code previously treated DIR_SHOW_IGNORED_TOO in most cases as an
exception as well, which was wrong. It can sometimes reduce the number
of cases where we need to recurse (namely if
DIR_SHOW_IGNORED_TOO_MODE_MATCHING is also set), but should not be able
to increase the number of cases where we need to recurse. Fix the logic
accordingly.
Some sidenotes about possible confusion with dir.c:
* "ignored" often refers to an untracked ignore", i.e. a file which is
not tracked which matches one of the ignore/exclusion rules. But you
can also have a "tracked ignore", a tracked file that happens to match
one of the ignore/exclusion rules and which dir.c has to worry about
since "git ls-files -c -i" is supposed to list them.
* The dir code often uses "ignored" and "excluded" interchangeably,
which you need to keep in mind while reading the code.
* "exclude" is used multiple ways in the code:
* As noted above, "exclude" is often a synonym for "ignored".
* The logic for parsing .gitignore files was re-used in
.git/info/sparse-checkout, except there it is used to mark paths that
the user wants to *keep*. This was mostly addressed by commit
65edd96aec ("treewide: rename 'exclude' methods to 'pattern'",
2019-09-03), but every once in a while you'll find a comment about
"exclude" referring to these patterns that might in fact be in use
by the sparse-checkout machinery for inclusion rules.
* The word "EXCLUDE" is also used for pathspec negation, as in
(pathspec->items[3].magic & PATHSPEC_EXCLUDE)
Thus if a user had a .gitignore file containing
*~
*.log
!settings.log
And then ran
git add -- 'settings.*' ':^settings.log'
Then :^settings.log is a pathspec negation making settings.log not
be requested to be added even though all other settings.* files are
being added. Also, !settings.log in the gitignore file is a negative
exclude pattern meaning that settings.log is normally a file we
want to track even though all other *.log files are ignored.
Sometimes it feels like dir.c needs its own glossary with its many
definitions, including the multiply-defined terms.

In the last commit, we added a testcase showing that the directory
traversal machinery sometimes traverses into directories unnecessarily.
Here we show that there are cases where it does the opposite: it does
not traverse into directories, despite those directories having
important files that need to be flagged.
Add a testcase showing that `git ls-files -o -i --directory` can omit
some of the files it should be listing, and another showing that `git
clean -fX` can fail to clean out some of the expected files.

The PNPM package manager is apparently creating deeply nested (but
ignored) directory structures; traversing them is costly
performance-wise, unnecessary, and in some cases is even throwing

ls-files --ignored can be used together with either --others or
--cached. After being perplexed for a bit and digging in to the code, I
assumed that ls-files -i was just broken and not printing anything and
I had a nice patch ready to submit when I finally realized that -i can be
used with --cached to find tracked ignores.
While that was a mistake on my part, and a careful reading of the
documentation could have made this more clear, I suspect this is an
error others are likely to make as well. In fact, of two uses in our
testsuite, I believe one of the two did make this error. In t1306.13,
there are NO tracked files, and all the excludes built up and used in
that test and in previous tests thus have to be about untracked files.
However, since they were looking for an empty result, the mistake went
unnoticed as their erroneous command also just happened to give an empty
answer.
-i will most the time be used with -o, which would suggest we could just
make -i imply -o in the absence of either a -o or -c, but that would be
a backward incompatible break. Instead, let's just flag -i without
either a -o or -c as an error, and update the two relevant testcases to
specify their intent.

used_atom.u is an union, and it has different members depending on
what atom the auxiliary data the union part of the "struct
used_atom" wants to record. At most only one of the members can be
valid at any one time. Since the code checks u.remote_ref without
even making sure if the atom is "push" or "push:" (which are only
two cases that u.remote_ref.push becomes valid), but u.remote_ref
shares the same storage for other members of the union, the check
was reading from an invalid member, which was the bug.
Modify the condition here to check whether the atom name

When deleting a packed ref via 'update-ref -d', a lockfile is made in
the directory that would contain the loose copy of that ref, creating
any directories in the ref's path that do not exist. When the
transaction completes, the lockfile is deleted, but any empty parent
directories made when creating the lockfile are left in place. These
empty directories are not removed by 'pack-refs' or other housekeeping
tasks and will accumulate over time.
When deleting a loose ref, we remove all empty parent directories at the
end of the transaction.
This commit applies the parent directory cleanup logic used when
deleting loose refs to packed refs as well.

Remove various redundant or obsolete code from the test_create_repo()
function, and split up its use in test-lib.sh from what tests need
from it.
This leave us with a pass-through wrapper for "git init" in
test-lib-functions.sh, in test-lib.sh we have the same, except for
needing to redirect stdout/stderr, and emitting an error ourselves if
it fails. We don't need to error() ourselves when test_create_repo()
is invoked, as the invocation will be a part of a test's "&&"-chain.
Everything below this paragraph is a detailed summary of the history
of test_create_repo() explaining why it's safe to remove the various
things it was doing:
1. "mkdir -p" isn't needed because "git init" itself will create
leading directories if needed.
2. Since we're now a simple wrapper for "git init" we don't need to
check that we have only one argument. If someone wants to run
"test_create_repo --bare x" that's OK.
3. We won't ever hit that "Cannot setup test environment"
error.
Checking the test environment sanity when doing "git init" dates
back to eea420693be (t0000: catch trivial pilot errors.,
2005-12-10) and 2ccd2027b01 (trivial: check, if t/trash directory
was successfully created, 2006-01-05).
We can also see it in another form a bit later in my own
0d314ce834d (test-lib: use subshell instead of cd $new && .. && cd
$old, 2010-08-30).
But since 2006f0adaee (t/test-lib: make sure Git has already been
built, 2012-09-17) we already check if we have a built git
earlier.
The one thing this was testing after that 2012 change was that
we'd just built "git", but not "git-init", but since
3af4c7156c4 (tests: respect GIT_TEST_INSTALLED when initializing
repositories, 2018-11-12) we invoke "git", not "git-init".
So all of that's been checked already, and we don't need to
re-check it here.
4. We don't need to move .git/hooks out of the way.
That dates back to c09a69a83e3 (Disable hooks during tests.,
2005-10-16), since then hooks became disabled by default in
f98f8cbac01 (Ship sample hooks with .sample suffix, 2008-06-24).
So the hooks were already disabled by default, but as can be seen
from "mkdir .git/hooks" changes various tests needed to re-setup
that directory. Now they no longer do.
This makes us implicitly depend on the default hooks being
disabled, which is a good thing. If and when we'd have any
on-by-default hooks (I see no reason we ever would) we'd want to
see the subtle and not so subtle ways that would break the test
suite.
5. We don't need to "cd" to the "$repo" directory at all anymore.
In the code being removed here we both "cd"'d to the repository
before calling "init", and did so in a subshell.
It's not important to do either, so both of those can be
removed. We cd'd because this code grew from test-lib.sh code
where we'd have done so already, see eedf8f97e58 (Abstract
test_create_repo out for use in tests., 2006-02-17), and later
"cd"'d inside a subshell since 0d314ce834d to avoid having to keep
track of an "old pwd" variable to cd back after the setup.
Being in the repository directory made moving the hooks around
easier (we wouldn't have to fully qualify the path). Since we're
not moving the hooks per #4 above we don't need to "cd" for that
reason either.
6. We can drop the --template argument and instead rely on the
GIT_TEMPLATE_DIR set to the same path earlier in test-lib.sh. See
8683a45d669 (Introduce GIT_TEMPLATE_DIR, 2006-12-19)
7. We only needed that ">&3 2>&4" redirection when invoked from
test-lib.sh.
We could still invoke test_create_repo() there, but as the
invocation is now trivial and we don't have a good reason to use
test_create_repo() elsewhere let's call "git init" there
ourselves.
8. We didn't need to resolve "git" as
"${GIT_TEST_INSTALLED:-$GIT_EXEC_PATH}/git$X" in test_create_repo(),
even for the use of test-lib.sh
PATH is already set up in test-lib.sh to start with
GIT_TEST_INSTALLED and/or GIT_EXEC_PATH before
test_create_repo() (now "git init") is called.. So we can simply
run "git" and rely on the PATH lookup choosing the right
executable.

Arrange for the advice about naming the initial branch not to be shown
in the --verbose output of the test suite.
Since 675704c74dd (init: provide useful advice about
init.defaultBranch, 2020-12-11) some tests have been very chatty with
repeated occurrences of this multi-line advice. Having it be this
verbose isn't helpful for anyone in the context of git's own test
suite, and it makes debugging tests that use their own "git init"
invocations needlessly distracting.
By setting the GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME variable early in
test-lib.sh itself we'll squash the warning not only for
test_create_repo(), as 675704c74dd explicitly intended, but also for
other "git init" invocations.
And once we'd like to have this configuration set for all "git init"
invocations in the test suite we can get rid of the init.defaultBranch
configuration setting in test_create_repo(), as
repo_default_branch_name() in refs.c will take the GIT_TEST_* variable
over it being set.

Change a use of $GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME added in
704fed9ea22 (tests: start moving to a different default main branch
name, 2020-10-23) to simply discover the initial branch name of a
repository set up in this function with "symbolic-ref --short".
That's something done in another test in 704fed9ea22, so doing it like
this seems like an omission, or rather an overly eager
search/replacement instead of fixing the test logic.
There are only three uses of the GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME

Add a --printf option to test_commit to allow writing to the file with

combination with the --append option added in 3373518cc8 (test-lib

I'm converting a few tests to use the new option rather than a manual

at it use "test_create_repo" where appropriate, and give the
first/second commit a meaningful/more conventional log message in
cases where no test cared about that message.

Convert the setup of the describe tests to use test_commit when
possible. This makes use of the new --annotate option to test_commit.
Some of the setup here could simply be removed since the data being
created wasn't important to any of the subsequent tests, so I've done
so. E.g. assigning to the "one" variable was always useless, and just
checking that we can describe HEAD after the first commit wasn't
useful.
In the case of the "two" variable we could instead use the tag we just
created. See 5312ab11fbf (Add describe test., 2007-01-13) for the
initial version of this code. There's other cases here like redundant
"test_tick" invocations, or the simplification of not echoing "X" to a
file we're about to tag as "x", now we just use "x" in both cases.

There's no point in creating a repository or directory only to decide
right afterwards that we're skipping all the tests. We can save
ourselves the redundant "git init" or "mkdir" and "rm -rf" in this
case.
We carry around the "$remove_trash" variable because if the directory
is unexpectedly gone at test_done time we'll still want to hit the
"trash directory already removed" error, but not if we never created
the trash directory. See df4c0d1a792 (test-lib: abort when can't
remove trash directory, 2017-04-20) for the addition of that error.
So let's partially revert 06478dab4c (test-lib: retire $remove_trash
variable, 2017-04-23) and move the decision about whether to skip all
tests earlier.
Let's also fix a bug that was with us since abc5d372ec (Enable
parallel tests, 2008-08-08): we would leak $remove_trash from the
environment. We don't want this to error out, so let's reset it to the
empty string first:
remove_trash=t GIT_SKIP_TESTS=t0001 ./t0001-init.sh
I tested this with --debug, see 4d0912a206 (test-lib.sh: do not barf
under --debug at the end of the test, 2017-04-24) for a bug we don't
want to re-introduce.
While I'm at it, let's move the HOME assignment to just before
test_create_repo, it could be lower, but it seems better to set it
before calling anything in test-lib-functions.sh

When SMTP servers receive 8-bit email messages, possibly with only
LF as line ending, some of them decide to change said LF to CRLF.
Some mailing list softwares, when receive 8-bit email messages,
decide to encode those messages in base64 or quoted-printable.
If an email is transfered through above mail servers, then distributed
by such mailing list softwares, the recipients will receive an email
contains a patch mungled with CRLF encoded inside another encoding.
Thus, such CR (in CRLF) couldn't be dropped by "mailsplit".
Hence, the mailed patch couldn't be applied cleanly.
Such accidents have been observed in the wild [1].
Instead of silently rejecting those messages, let's give our users
some warnings if such CR (as part of CRLF) is found.

If find_word_boundaries() encounters a zero length match (which can be
caused by matching a newline or using '*' instead of '+' in the regex)
we stop splitting the input into words which generates an inaccurate
diff. To fix this increment the start point when there is a zero
length match and try a new match. This is safe as posix regular
expressions always return the longest available match so a zero length
match means there are no longer matches available from the current
position.
Commit bf82940dbf1 (color-words: enable REG_NEWLINE to help user,
2009-01-17) prevented matching newlines in negated character classes
but it is still possible for the user to have an explicit newline
match in the regex which could cause a zero length match.
One could argue that having explicit newline matches or using '*'
rather than '+' are user errors but it seems to be better to work
round them than produce inaccurate diffs.

We already have tests for the basic parallel-checkout operations. But
this code can also run be executed by other commands, such as
git-read-tree and git-sparse-checkout, which are currently not tested
with multiple workers. To promote a wider test coverage without
duplicating tests:
1. Add the GIT_TEST_CHECKOUT_WORKERS environment variable, to optionally
force parallel-checkout execution during the whole test suite.
2. Set this variable (with a value of 2) in the second test round of our
linux-gcc CI job. This round runs `make test` again with some
optional GIT_TEST_* variables enabled, so there is no additional
overhead in exercising the parallel-checkout code here.
Note that tests checking out less than two parallel-eligible entries
will fall back to the sequential mode. Nevertheless, it's still a good
exercise for the parallel-checkout framework as the fallback codepath
also writes the queued entries using the parallel-checkout functions
(only without spawning any worker).

A HTTP-clone test introduced in 4fe788b1b0 ("builtin/clone.c: add
--reject-shallow option", 2021-04-01) only works in protocol v2, but is
not marked as such.
The aforementioned patch implements --reject-shallow for a variety of
situations, but usage of a protocol that requires a remote helper is not
one of them. (Such an implementation would require extending the remote
helper protocol to support the passing of a "reject shallow" option, and
then teaching it to both protocol-speaking ends.)
For now, to make it pass when GIT_TEST_PROTOCOL_VERSION=0 is passed, add
"-c protocol.version=2". A more complete solution would be either to
augment the remote helper protocol to support this feature or to return
a fatal error when using --reject-shallow with a protocol that uses a
remote helper.

Currently, the packfile negotiation step within a Git fetch cannot be
done independent of sending the packfile, even though there is at least
one application wherein this is useful. Therefore, make it possible for
this negotiation step to be done independently. A subsequent commit will
use this for one such application - push negotiation.
This feature is for protocol v2 only. (An implementation for protocol v0
would require a separate implementation in the fetch, transport, and
transport helper code.)
In the protocol, the main hindrance towards independent negotiation is
that the server can unilaterally decide to send the packfile. This is
solved by a "wait-for-done" argument: the server will then wait for the
client to say "done". In practice, the client will never say it; instead
it will cease requests once it is satisfied.
In the client, the main change lies in the transport and transport
helper code. fetch_refs_via_pack() performs everything needed - protocol
version and capability checks, and the negotiation itself.
There are 2 code paths that do not go through fetch_refs_via_pack() that
needed to be individually excluded: the bundle transport (excluded
through requiring smart_options, which the bundle transport doesn't
support) and transport helpers that do not support takeover. If or when
we support independent negotiation for protocol v0, we will need to
modify these 2 code paths to support it. But for now, report failure if
independent negotiation is requested in these cases.

The `trailer.<token>.command` configuration variable
specifies a command (run via the shell, so it does not have
to be a single name or path to the command, but can be a
shell script), and the first occurrence of substring $ARG is
replaced with the value given to the `interpret-trailer`
command for the token in a '--trailer <token>=<value>' argument.
This has three downsides:
* The use of $ARG in the mechanism misleads the users that
the value is passed in the shell variable, and tempt them
to use $ARG more than once, but that would not work, as
the second and subsequent $ARG are not replaced.
* Because $ARG is textually replaced without regard to the
shell language syntax, even '$ARG' (inside a single-quote
pair), which a user would expect to stay intact, would be
replaced, and worse, if the value had an unmatched single
quote (imagine a name like "O'Connor", substituted into
NAME='$ARG' to make it NAME='O'Connor'), it would result in
a broken command that is not syntactically correct (or
worse).
* The first occurrence of substring `$ARG` will be replaced
with the empty string, in the command when the command is
first called to add a trailer with the specified <token>.
This is a bad design, the nature of automatic execution
causes it to add a trailer that we don't expect.
Introduce a new `trailer.<token>.cmd` configuration that
takes higher precedence to deprecate and eventually remove
`trailer.<token>.command`, which passes the value as an
argument to the command. Instead of "$ARG", users can
refer to the value as positional argument, $1, in their
scripts. At the same time, in order to allow
`git interpret-trailers` to better simulate the behavior
of `git command -s`, 'trailer.<token>.cmd' will not
automatically execute.

In the commits merged in via 204333b015 (Merge branch
'jk/open-dotgitx-with-nofollow', 2021-03-22), we stopped following
symbolic links for .gitattributes, .gitignore, and .mailmap files.
Let's teach fsck to warn that these symlinks are not going to do
anything. Note that this is just a warning, and won't block the objects
via transfer.fsckObjects, since there are reported to be cases of this
in the wild (and even once fixed, they will continue to exist in the
commit history of those projects, but are not particularly dangerous).
Note that we won't add these to the existing gitmodules block in the
fsck code. The logic for gitmodules is a bit more complicated, as we
also check the content of non-symlink instances we find. But for these
new files, there is no content check; we're just looking at the name and
mode of the tree entry (and we can avoid even the complicated name
checks in the common case that the mode doesn't indicate a symlink).
We can reuse the test helper function we defined for .gitmodules, though
(it needs some slight adjustments for the fsck error code, and because
we don't block these symlinks via verify_path()).
Note that I didn't explicitly test the transfer.fsckObjects case here
(nor does the existing .gitmodules test that it blocks a push). The
translation of fsck severities to outcomes is covered in general in
t5504.

add tests, 2018-05-12), with the actual code coming from e7cb0b4455
(is_ntfs_dotgit: match other .git files, 2018-05-11) and 0fc333ba20
(is_hfs_dotgit: match other .git files, 2018-05-02).
Those latter two commits also added similar matching functions for
.gitattributes and .gitignore. These ended up not being used in the
final series, and are currently dead code. But in preparation for them
being used in some fsck checks, let's make sure they actually work by
throwing a few basic tests at them. Likewise, let's cover .mailmap
(which does need matching code added).
I didn't bother with the whole battery of tests that we cover for
.gitmodules. These functions are all based on the same generic matcher,
so it's sufficient to test most of the corner cases just once.
Note that the ntfs magic prefix names in the tests come from the
algorithm described in e7cb0b4455 (and are different for each file).

In t7450 we check that both verify_path() and fsck catch malformed
.gitmodules entries in trees. However, we don't check that we catch
filesystem-equivalent forms of these (e.g., ".GITMOD~1" on Windows).
Our name-matching functions are exercised well in t0060, but there's
nothing to test that we correctly call the matching functions from the
actual fsck and verify_path() code.
So instead of testing just .gitmodules, let's repeat our tests for a few
basic cases. We don't need to be exhaustive here (t0060 handles that),
but just make sure we hit one name of each type.
Besides pushing the tests into a function that takes the path as a
parameter, we'll need to do a few things:
- adjust the directory name to accommodate the tests running multiple
times
- set core.protecthfs for index checks. Fsck always protects all types
by default, but we want to be able to exercise the HFS routines on
every system. Note that core.protectntfs is already the default
these days, but it doesn't hurt to explicitly label our need for it.
- we'll also take the filename ("gitmodules") as a parameter. All
calls use the same name for now, but a future patch will extend this
to handle other .gitfoo files. Note that our fake-content symlink
destination is somewhat .gitmodules specific. But it isn't necessary
for other files (which don't do a content check). And it happens to
be a valid attribute and ignore file anyway.

Commit b2f2039c2b (fsck: accept an oid instead of a "struct tree" for
fsck_tree(), 2019-10-18) introduced a new "oid" parameter to
fsck_tree(), and we pass it to the report() function when we find
problems. However, that is shadowed within the tree-walking loop by the
existing "oid" variable which we use to store the oid of each tree
entry. As a result, we may report the wrong oid for some problems we
detect within the loop (the entry oid, instead of the tree oid).
Our tests didn't catch this because they checked only that we found the
expected fsck problem, not that it was attached to the correct object.
Let's rename both variables in the function to avoid confusion. This
makes the diff a little noisy (e.g., all of the report() calls outside
the loop were already correct but need to be touched), but makes sure we
catch all cases and will avoid similar confusion in the future.
And we can update the test to be a bit more specific and catch this
problem.

A negative delta depth makes no sense, and the code is not prepared to
handle it. If passed "--depth=-1" on the command line, then this line
from break_delta_chains():
cur->depth = (total_depth--) % (depth + 1);
triggers a divide-by-zero. This is undefined behavior according to the C
standard, but on POSIX systems results in SIGFPE killing the process.
This is certainly one way to inform the use that the command was
invalid, but it's a bit friendlier to just treat it as "don't allow any
deltas", which we already do for --depth=0.

We could complain to the user about this, but it's more forgiving to
just clamp it to 0, which means "do not find any deltas at all". The
0-case is already tested earlier in the script, so we'll make sure this

The first set of tests in t5300 goes back to 2005, and doesn't use some
of our customary style and tools these days. In preparation for touching
them, let's modernize a few things:
- titles go on the line with test_expect_success, with a hanging
open-quote to start the test body
- test bodies should be indented with tabs
- opening braces for shell blocks in &&-chains go on their own line
- no space between redirect operators and files (">foo", not "> foo")
- avoid doing work outside of test blocks; in this case, we can stick
the setup of ".git2" into the appropriate blocks
- avoid modifying and then cleaning up the environment or current
directory by using subshells and "git -C"
- this test does a curious thing when testing the unpacking: it sets
GIT_OBJECT_DIRECTORY, and then does a "git init" in the _original_
directory, creating a weird mixed situation. Instead, it's much
simpler to just "git init --bare" a new repository to unpack into,
and check the results there. I renamed this "git2" instead of
".git2" to make it more clear it's a separate repo.
- we can observe that the bodies of the no-delta, ref_delta, and
ofs_delta cases are all virtually identical except for the pack
creation, and factor out shared helper functions. I collapsed "do
the unpack" and "check the results of the unpack" into a single
test, since that makes the expected lifetime of the "git2" temporary
directory more clear (that also lets us use test_when_finished to
clean it up). This does make the "-v" output slightly less useful,
but the improvement in reading the actual test code makes it worth
it.
- I dropped the "pwd" calls from some tests. These don't do anything
functional, and I suspect may have been an aid for debugging when
the script was more cavalier about leaving the working directory
changed between tests.

Commit e4c7b33747 ("bisect--helper: reimplement `bisect_skip` shell
function in C", 2021-02-03), as part of the shell-to-C conversion,
forgot to read the 'terms' file (.git/BISECT_TERMS) during the new
'bisect skip' command implementation. As a result, the 'bisect skip'
command will use the default 'bad'/'good' terms. If the bisection
terms have been set to non-default values (for example by the
'bisect start' command), then the 'bisect skip' command will fail.
In order to correct this problem, we insert a call to the get_terms()
function, which reads the non-default terms from that file (if set),
in the '--bisect-skip' command implementation of 'bisect--helper'.
Also, add a test[1] to protect against potential future regression.

The backslash character is not a valid part of a file name on Windows.
If, in Windows, Git attempts to write a file that has a backslash
character in the filename, it will be incorrectly interpreted as a
directory separator.
This caused CVE-2019-1354 in MinGW, as this behaviour can be manipulated
to cause the checkout to write to files it ought not write to, such as
adding code to the .git/hooks directory. This was fixed by e1d911dd4c
(mingw: disallow backslash characters in tree objects' file names,
2019-09-12). However, the vulnerability also exists in Cygwin: while
Cygwin mostly provides a POSIX-like path system, it will still interpret
a backslash as a directory separator.
To avoid this vulnerability, CVE-2021-29468, extend the previous fix to
also apply to Cygwin.
Similarly, extend the test case added by the previous version of the
commit. The test suite doesn't have an easy way to say "run this test
if in MinGW or Cygwin", so add a new test prerequisite that covers both.
As well as checking behaviour in the presence of paths containing
backslashes, the existing test also checks behaviour in the presence of
paths that differ only by the presence of a trailing ".". MinGW follows
normal Windows application behaviour and treats them as the same path,
but Cygwin more closely emulates *nix systems (at the expense of
compatibility with native Windows applications) and will create and
distinguish between such paths. Gate the relevant bit of that test
accordingly.

We pass our prune expiration to mark_reachable_objects(), which will
traverse not only the reachable objects, but consider any recent ones as
tips for reachability; see d3038d22f9 (prune: keep objects reachable
from recent objects, 2014-10-15) for details.
However, this interacts badly with the bitmap code path added in
fde67d6896 (prune: use bitmaps for reachability traversal, 2019-02-13).
If we hit the bitmap-optimized path, we return immediately to avoid the
regular traversal, accidentally skipping the "also traverse recent"
code.
Instead, we should do an if-else for the bitmap versus regular
traversal, and then follow up with the "recent" traversal in either
case. This reuses the "rev_info" for a bitmap and then a regular
traversal, but that should work OK (the bitmap code clears the pending
array in the usual way, just like a regular traversal would).
Note that I dropped the comment above the regular traversal here. It
has little explanatory value, and makes the if-else logic much harder to
read.
Here are a few variants that I rejected:
- it seems like both the reachability and recent traversals could be
done in a single traversal. This was rejected by d3038d22f9 (prune:
keep objects reachable from recent objects, 2014-10-15), though the
balance may be different when using bitmaps. However, there's a
subtle correctness issue, too: we use revs->ignore_missing_links for
the recent traversal, but not the reachability one.
- we could try using bitmaps for the recent traversal, too, which
could possibly improve performance. But it would require some fixes
in the bitmap code, which uses ignore_missing_links for its own
purposes. Plus it would probably not help all that much in practice.
We use the reachable tips to generate bitmaps, so those objects are
likely not covered by bitmaps (unless they just became unreachable).
And in general, we expect the set of unreachable objects to be much
smaller anyway, so there's less to gain.
The test in t5304 detects the bug and confirms the fix.
I also beefed up the tests in t6501, which covers the mtime-checking
code more thoroughly, to handle the bitmap case (in addition to just
"loose" and "packed" cases). Interestingly, this test doesn't actually
detect the bug, because it is running "git gc", and not "prune"
directly. And "gc" will call "repack" first, which does not suffer the
same bug. So the old-but-reachable-from-recent objects get scooped up
into the new pack along with the actually-recent objects, which gives
both a recent mtime. But it seemed prudent to get more coverage of the
bitmap case for related code.

When `git repack -A -d` is run in a partial clone, `pack-objects`
is invoked twice: once to repack all promisor objects, and once to
repack all non-promisor objects. The latter `pack-objects` invocation
is with --exclude-promisor-objects and --unpack-unreachable, which
loosens all objects unused during this invocation. Unfortunately,
this includes promisor objects.
Because the -d argument to `git repack` subsequently deletes all loose
objects also in packs, these just-loosened promisor objects will be
immediately deleted. However, this extra disk churn is unnecessary in
the first place. For example, in a newly-cloned partial repo that
filters all blob objects (e.g. `--filter=blob:none`), `repack` ends up
unpacking all trees and commits into the filesystem because every
object, in this particular case, is a promisor object. Depending on
the repo size, this increases the disk usage considerably: In my copy
of the linux.git, the object directory peaked 26GB of more disk usage.
In order to avoid this extra disk churn, pass the names of the promisor
packfiles as --keep-pack arguments to the second invocation of
`pack-objects`. This informs `pack-objects` that the promisor objects
are already in a safe packfile and, therefore, do not need to be
loosened.
For testing, we need to validate whether any object was loosened.
However, the "evidence" (loosened objects) is deleted during the
process which prevents us from inspecting the object directory.
Instead, let's teach `pack-objects` to count loosened objects and
emit via trace2 thus allowing inspecting the debug events after the
process is finished. This new event is used on the added regression
test.
Lastly, add a new perf test to evaluate the performance impact
made by this changes (tested on git.git):
Test HEAD^ HEAD
----------------------------------------------------------
5600.3: gc 134.38(41.93+90.95) 7.80(6.72+1.35) -94.2%
For a bigger repository, such as linux.git, the improvement is
even bigger:
Test HEAD^ HEAD
-------------------------------------------------------------------
5600.3: gc 6833.00(918.07+3162.74) 268.79(227.02+39.18) -96.1%
These improvements are particular big because every object in the
newly-cloned partial repository is a promisor object.

With the introduction of the $__git_cmd_idx variable in e94fb44042
(git-completion.bash: pass $__git_subcommand_idx from __git_main(),
2021-03-24), completion functions were able to know the index at which
the git command is listed, allowing them to skip options that are given
to the underlying git itself, not the corresponding command (e.g.
`-C asdf` in `git -C asdf branch`).
While most of the changes here are self-explanatory, some bear further
explanation.
For the __git_find_on_cmdline() and __git_find_last_on_cmdline() pair of
functions, these functions are only ever called in the context of a git
command completion function. These functions will only care about words
after the command so we can safely ignore the words before this.
For _git_worktree(), this change is technically a no-op (once the
__git_find_last_on_cmdline change is also applied). It was in poor style
to have hard-coded on the index right after `worktree`. In case
`git worktree` were to ever learn to accept options, the current
situation would be inflexible.

In order to have git run in a fully controlled environment without any
misconfiguration, it may be desirable for users or scripts to override
global- and system-level configuration files. We already have a way of
doing this, which is to unset both HOME and XDG_CONFIG_HOME environment
variables and to set `GIT_CONFIG_NOGLOBAL=true`. This is quite kludgy,
and unsetting the first two variables likely has an impact on other
executables spawned by such a script.
The obvious way to fix this would be to introduce `GIT_CONFIG_NOGLOBAL`
as an equivalent to `GIT_CONFIG_NOSYSTEM`. But in the past, it has
turned out that this design is inflexible: we cannot test system-level
parsing of the git configuration in our test harness because there is no
way to change its location, so all tests run with `GIT_CONFIG_NOSYSTEM`
set.
Instead of doing the same mistake with `GIT_CONFIG_NOGLOBAL`, introduce
two new variables `GIT_CONFIG_GLOBAL` and `GIT_CONFIG_SYSTEM`:
- If unset, git continues to use the usual locations.
- If set to a specific path, we skip reading the normal
configuration files and instead take the path. By setting the path
to `/dev/null`, no configuration will be loaded for the respective
level.
This implements the usecase where we want to execute code in a sanitized
environment without any potential misconfigurations via `/dev/null`, but
is more flexible and allows for more usecases than simply adding
`GIT_CONFIG_NOGLOBAL`.

When providing an object filter, it is currently impossible to also
filter provided items. E.g. when executing `git rev-list HEAD` , the
commit this reference points to will be treated as user-provided and is
thus excluded from the filtering mechanism. This makes it harder than
necessary to properly use the new `--filter=object:type` filter given

When the user has multiple objects filters specified, then this is
internally represented by having a "combined" filter. These combined
filters aren't yet supported by bitmap indices and can thus not be
accelerated.
Fix this by implementing support for these combined filters. The
implementation is quite trivial: when there's a combined filter, we
simply recurse into `filter_bitmap()` for all of the sub-filters.

While it already is possible to filter objects by some criteria in
git-rev-list(1), it is not yet possible to filter out only a specific
type of objects. This makes some filters less useful. The `blob:limit`
filter for example filters blobs such that only those which are smaller
than the given limit are returned. But it is unfit to ask only for these
smallish blobs, given that git-rev-list(1) will continue to print tags,
commits and trees.
Now that we have the infrastructure in place to also filter tags and
commits, we can improve this situation by implementing a new filter
which selects objects based on their type. Above query can thus
trivially be implemented with the following command:
$ git rev-list --objects --filter=object:type=blob \
--filter=blob:limit=200
Furthermore, this filter allows to optimize for certain other cases: if
for example only tags or commits have been selected, there is no need to
walk down trees.
The new filter is not yet supported in bitmaps. This is going to be
implemented in a subsequent commit.

The 'prefetch' maintenance task previously forced the following refspec
for each remote:
+refs/heads/*:refs/prefetch/<remote>/*
If a user has specified a more strict refspec for the remote, then this
prefetch task downloads more objects than necessary.
The previous change introduced the '--prefetch' option to 'git fetch'
which manipulates the remote's refspec to place all resulting refs into
refs/prefetch/, with further partitioning based on the destinations of
those refspecs.
Update the documentation to be more generic about the destination refs.
Do not mention custom refspecs explicitly, as that does not need to be
highlighted in this documentation. The important part of placing refs in
refs/prefetch/ remains.

The --prefetch option will be used by the 'prefetch' maintenance task
instead of sending refspecs explicitly across the command-line. The
intention is to modify the refspec to place all results in
refs/prefetch/ instead of anywhere else.
Create helper method filter_prefetch_refspec() to modify a given refspec
to fit the rules expected of the prefetch task:
* Negative refspecs are preserved.
* Refspecs without a destination are removed.
* Refspecs whose source starts with "refs/tags/" are removed.
* Other refspecs are placed within "refs/prefetch/".
Finally, we add the 'force' option to ensure that prefetch refs are
replaced as necessary.
There are some interesting cases that are worth testing.
An earlier version of this change dropped the "i--" from the loop that
deletes a refspec item and shifts the remaining entries down. This
allowed some refspecs to not be modified. The subtle part about the
first --prefetch test is that the "refs/tags/*" refspec appears directly
before the "refs/heads/bogus/*" refspec. Without that "i--", this
ordering would remove the "refs/tags/*" refspec and leave the last one
unmodified, placing the result in "refs/heads/*".
It is possible to have an empty refspec. This is typically the case for
remotes other than the origin, where users want to fetch a specific tag
or branch. To correctly test this case, we need to further remove the
upstream remote for the local branch. Thus, we are testing a refspec
that will be deleted, leaving nothing to fetch.

When --exclude-promisor-objects is given, before traversing any objects
we iterate over all of the objects in any promisor packs, marking them
as UNINTERESTING and SEEN. We turn the oid we get from iterating the
pack into an object with parse_object(), but this has two problems:
- it's slow; we are zlib inflating (and reconstructing from deltas)
every byte of every object in the packfile
- it leaves the tree buffers attached to their structs, which means
our heap usage will grow to store every uncompressed tree
simultaneously. This can be gigabytes.
We can obviously fix the second by freeing the tree buffers after we've
parsed them. But we can observe that the function doesn't look at the
object contents at all! The only reason we call parse_object() is that
we need a "struct object" on which to set the flags. There are two
options here:
- we can look up just the object type via oid_object_info(), and then
call the appropriate lookup_foo() function
- we can call lookup_unknown_object(), which gives us an OBJ_NONE
struct (which will get auto-converted later by object_as_type() via
calls to lookup_commit(), etc).
The first one is closer to the current code, but we do pay the price to
look up the type for each object. The latter should be more efficient in
CPU, though it wastes a little bit of memory (the "unknown" object
structs are a union of all object types, so some of the structs are
bigger than they need to be). It also runs the risk of triggering a
latent bug in code that calls lookup_object() directly but isn't ready
to handle OBJ_NONE (such code would already be buggy, but we use
lookup_unknown_object() infrequently enough that it might be hiding).
I went with the second option here. I don't think the risk is high (and
we'd want to find and fix any such bugs anyway), and it should be more
efficient overall.
The new tests in p5600 show off the improvement (this is on git.git):
Test HEAD^ HEAD
-------------------------------------------------------------------------------
5600.5: count commits 0.37(0.37+0.00) 0.38(0.38+0.00) +2.7%
5600.6: count non-promisor commits 11.74(11.37+0.37) 0.04(0.03+0.00) -99.7%
The improvement is particularly big in this script because _every_
object in the newly-cloned partial repo is a promisor object. So after
marking them all, there's nothing left to traverse.

All of the other lookup_foo() functions take a repository argument, but
lookup_unknown_object() was never converted, and it uses the_repository
internally. Let's fix that.
We could leave a wrapper that uses the_repository, but there aren't that
many calls, so we'll just convert them all. I looked briefly at each
site to see if we had a repository struct (besides the_repository) we
could pass, but none of them do (so this conversion to pass
the_repository is a pure noop in each case, though it does take us one
step closer to eventually getting rid of the_repository).

To get the list of all promisor objects, we not only include all objects
in promisor packs, but also parse each of those objects to see which
objects they reference. After parsing a tree object, the tree->buffer
field will remain populated until we explicitly free it. So in a partial
clone of blob:none, for example, we are essentially reading every tree
in the repository (since they're all in the initial promisor pack), and
keeping all of their uncompressed contents in memory at once.
This patch frees the tree buffers after we've finished marking all of
their reachable objects. We shouldn't need to do this for any other
object type. While we are using some extra memory to store the structs,
no other object type stores the whole contents in its parsed form (we do
sometimes hold on to commit buffers, but less so these days due to
commit graphs, plus most commands which care about promisor objects turn
off the save_commit_buffer global).
Even for a moderate-sized repository like git.git, this patch drops the
peak heap (as measured by massif) for git-fsck from ~1.7GB to ~138MB.
Fsck is a good candidate for measuring here because it doesn't interact
with the promisor code except to call is_promisor_object(), so we can
isolate just this problem.
The added perf test shows only a tiny improvement on my machine for
git.git, since 1.7GB isn't enough to cause any real memory pressure:
Test HEAD^ HEAD
--------------------------------------------------------------------------------
5600.4: fsck 21.26(20.90+0.35) 20.84(20.79+0.04) -2.0%
With linux.git the absolute change is a bit bigger, though still a small
percentage:
Test HEAD^ HEAD
-----------------------------------------------------------------------------
5600.4: fsck 262.26(259.13+3.12) 254.92(254.62+0.29) -2.8%
I didn't have the patience to run it under massif with linux.git, but
it's probably on the order of about 14GB improvement, since that's the
sum of the sizes of all of the uncompressed trees (but still isn't
enough to create memory pressure on this particular machine, which has
64GB of RAM). Smaller machines would probably see a bigger effect on
runtime (and sadly our perf suite does not measure peak heap).

When serving a clone or fetch with bitmaps, after deciding which objects
need to be sent our "pack reuse" mechanism kicks in: we try to send
more-or-less verbatim a bunch of objects from the beginning of the
bitmapped packfile without even adding them to the to_pack.objects
array.
After deciding which objects will be in the "reused" portion, we update
nr_result to account for those, and then trigger display_progress() to
show the user (who is undoubtedly dazzled that we managed to enumerate
so many objects so quickly).
But then something confusing happens: the "Enumerating objects" progress
meter jumps _backwards_, counting up from zero the number of objects we
actually add into to_pack.objects.
This worked correctly once upon a time, but was broken in 5af050437a
(pack-objects: show some progress when counting kept objects,
2018-04-15), when the latter half of that progress meter switched to
using a separate nr_seen counter, rather than nr_result. Nobody noticed
for two reasons:
- prior to the pack-reuse fixes from a14aebeac3 (Merge branch
'jk/packfile-reuse-cleanup', 2020-02-14), the reuse code almost
never kicked in anyway
- the output looks _kind of_ correct. The "backwards" moment is hard
to catch, because we overwrite the old progress number with the new
one, and the larger number is displayed only for a second. So unless
you look at that exact second, you just see the much smaller value,
counting up to the number of non-reused objects (though of course if
you catch it in stderr, or look at GIT_TRACE_PACKET from a server
with bitmaps, you can see both values).
This smaller output isn't wrong per se, but isn't counting what we ever
intended to. We should give the user the whole number of objects we
considered (which, as per 5af050437a's original purpose, is already
_not_ a count of what goes into to_pack.objects). The follow-on
"Counting objects" meter shows the actual number of objects we feed into
that array.
We can easily fix this by bumping (and showing) nr_seen for the
pack-reused objects. When the included test is run without this patch,
the second pack-objects invocation produces "Enumerating objects: 1" to
show the one loose object, even though the resulting pack has hundreds
of objects in it. With it, we jump to "Enumerating objects: 674" after
deciding on reuse, and then "675" when we add in the loose object.

Fix a bug in how --no-reschedule-failed-exec interacts with
rebase.rescheduleFailedExec=true being set in the config. Before this
change the --no-reschedule-failed-exec config option would be
overridden by the config.
This bug happened because of the particulars of how "rebase" works
v.s. most other git commands when it comes to parsing options and
config:
When we read the config and parse the CLI options we correctly prefer
the --no-reschedule-failed-exec option over
rebase.rescheduleFailedExec=true in the config. So far so good.
However the --reschedule-failed-exec option doesn't take effect when
the rebase starts (we'd just create a
".git/rebase-merge/reschedule-failed-exec" file if it was true). It
only takes effect when the exec command fails, at which point we'll
reschedule the failed "exec" command.
Since we only wrote out the positive
".git/rebase-merge/reschedule-failed-exec" under
--reschedule-failed-exec, but nothing with --no-reschedule-failed-exec
we'll forget that we asked not to reschedule failed "exec", and would
happily re-read the config and see that
rebase.rescheduleFailedExec=true is set.
So the config will effectively override the user having explicitly
disabled the option on the command-line.
Even more confusingly: Since rebase accepts different options based on
its state there wasn't even a way to get around this with "rebase
--continue --no-reschedule-failed-exec" (but you could of course set
the config with "rebase -c ...").
I think the least bad way out of this is to declare that for such
options and config whatever we decide at the beginning of the rebase
goes. So we'll now always create either a "reschedule-failed-exec" or
a "no-reschedule-failed-exec file at the start, not just the former if
we decided we wanted the feature.
With this new worldview you can no longer change the setting once a
rebase has started except by manually removing the state files
discussed above. I think making it work like that is the the least
confusing thing we can do.
In the future we might want to learn to change the setting in the
middle by combining "--edit-todo" with
"--[no-]reschedule-failed-exec", we currently don't support combining
those options, or any other way to change the state in the middle of
the rebase short of manually editing the files in
".git/rebase-merge/*".
The bug being fixed here originally came about because of a
combination of the behavior of the code added in d421afa0c66 (rebase:
introduce --reschedule-failed-exec, 2018-12-10) and the addition of
the config variable in 969de3ff0e0 (rebase: add a config option to
default to --reschedule-failed-exec, 2018-12-10).

Add a diff driver for Scheme-like languages which recognizes top level
and local `define` forms, whether it is a function definition, binding,
syntax definition or a user-defined `define-xyzzy` form.
Also supports R6RS `library` forms, `module` forms along with class and
struct declarations used in Racket (PLT Scheme).
Alternate "def" syntax such as those in Gerbil Scheme are also
supported, like defstruct, defsyntax and so on.
The rationale for picking `define` forms for the hunk headers is because
it is usually the only significant form for defining the structure of
the program, and it is a common pattern for schemers to have local
function definitions to hide their visibility, so it is not only the top
level `define`'s that are of interest. Schemers also extend the language
with macros to provide their own define forms (for example, something
like a `define-test-suite`) which is also captured in the hunk header.
Since it is common practice to extend syntax with variants of a form
like `module+`, `class*` etc, those have been supported as well.
The word regex is a best-effort attempt to conform to R7RS[1] valid
identifiers, symbols and numbers.

Simplify the test added in 9466e3809d (blame: enable funcname blaming
with userdiff driver, 2020-11-01) to use the --author support recently
added in 999cfc4f45 (test-lib functions: add --author support to
test_commit, 2021-01-12).
We also did not need the full fortran-external-function content. Let's
cut it down to just the important parts.
I'm modifying it to demonstrate that the fortran-specific userdiff
function is in effect by adding "DO NOT MATCH ..." and "AS THE ..."
lines surrounding the "RIGHT" one.
This is to check that we're using the userdiff "fortran" driver, as
opposed to the default driver which would match on those lines as part
of the general heuristic of matching a line that doesn't begin with
whitespace.
The test had also been leaving behind a .gitattributes file for later
tests to possibly trip over, let's clean it up with
"test_when_finished".

Refactor a test added in 9466e3809d (blame: enable funcname blaming
with userdiff driver, 2020-11-01) so that the blame tests don't rely
on stealing the contents of "t/t4018/fortran-external-function".
I have another patch series that'll possibly (or not) refactor that
file, but having this test inter-dependency makes things simple in any
case by making this test more readable.

Change the userdiff test to list the builtin drivers via the
test-tool, using the new for_each_userdiff_driver() API function.
This gets rid of the need to modify this part of the test every time a
new pattern is added, see 2ff6c34612 (userdiff: support Bash,
2020-10-22) and 09dad9256a (userdiff: support Markdown, 2020-05-02)
for two recent examples.
I only need the "list-builtin-drivers "argument here, but let's add
"list-custom-drivers" and "list-drivers" too, just because it's easy.

Since 122aa6f9c0 (diff: introduce diff.<driver>.binary, 2008-10-05)
the internals of the userdiff.c code have understood a "default" name,
which is invoked as userdiff_find_by_name("default") and present in
the "builtin_drivers" struct. Let's test for this special case.

"git apply" does not allow "--cached" and "--3way" to be used
together, since "--3way" writes conflict markers into the working
tree.
Allow "git apply" to accept "--cached" and "--3way" at the same
time. When a single file auto-resolves cleanly, the result is
placed in the index at stage #0 and the command exits with 0 status.
For a file that has a conflict which cannot be cleanly
auto-resolved, the original contents from common ancestor (stage
conflict at the content level, and the command exists with non-zero
status, because there is no place (like the working tree) to leave a
half-resolved merge for the user to resolve.
The user can use `git diff` to view the contents of the conflict, or
`git checkout -m -- .` to regenerate the conflict markers in the
working directory.
Don't attempt rerere in this case since it depends on conflict
markers written to file for its database storage and lookup. There
would be two main changes required to get rerere working:
1. Allow the rerere api to accept in memory object rather than
files, which would allow us to pass in the conflict markers
contained in the result from ll_merge().
2. Rerere can't write to the working directory, so it would have to
apply the result to cache stage #0 directly. A flag would be
needed to control this.

The apply_fragments() method of "git apply"
can silently apply patches incorrectly if
a file has repeating contents. In these
cases a three-way merge is capable of applying
it correctly in more situations, and will
show a conflict rather than applying it
incorrectly. However, because the patches
apply "successfully" using apply_fragments(),
git will never fall back to the merge, even
if the "--3way" flag is used, and the user has
no way to ensure correctness by forcing the
three-way merge method.
Change the behavior so that when "--3way" is used,
git will always try the three-way merge first and
will only fall back to apply_fragments() in cases
where blobs are not available or some other error
(but not in the case of a merge conflict).
Since user-facing results will be different,
this has backwards compatibility implications
for users depending on the old behavior. In
addition, the three-way merge will be slower
than direct patch application.

Improve the output we emit on --validate error to:
* Say "FILE:LINE" instead of "FILE: LINE", to match "grep -n",
compiler error messages etc.
* Don't say "patch contains a" after just mentioning the filename,
just leave it at "FILE:LINE: is longer than[...]. The "contains a"
sounded like we were talking about the file in general, when we're
actually checking it line-by-line.
* Don't just say "rejected by sendemail-validate hook", but combine
that with the system_or_msg() output to say what exit code the hook
died with.
I had an aborted attempt to make the line length checker note all
lines that were longer than the limit. I didn't think that was worth
the effort, but I've left in the testing change to check that we die
as soon as we spot the first long line.
