2e4e43a691 t7300: add testcase showing unnecessary traversal into ignored directory
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
warnings/errors because the paths are too long to handle on various
platforms.  Add a testcase that checks for such unnecessary directory
traversal.

b338e9f668 ls-files: error out on -i unless -o or -c are specified
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.

1e1c4c5eac ref-filter: fix read invalid union member bug
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
equals to "push" or starts with "push:", to avoid reading the
value of invalid member of the union.

5f03e5126d refs: cleanup directories when deleting packed ref
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.

33b4ae1114 describe tests: fix nested "test_expect_success" call
Fix a nested invocation of "test_expect_success", the
"check_describe()" function is a wrapper for calling
test_expect_success, and therefore needs to be called outside the body
of another "test_expect_success".

The two tests added in 30b1c7ad9d (describe: don't abort too early
when searching tags, 2020-02-26) were not testing for anything due to
this logic error. Without this fix reverting the C code changes in
that commit still has all tests passing, with this fix we're actually
testing the "describe" output. This is because "test_expect_success"
calls "test_finish_", whose last statement happens to be true.

7f07c1cdb7 describe tests: don't rely on err.actual from "check_describe"
Convert the one test that relied on the "err.actual" file produced by
check_describe() to instead do its own check of "git describe"
output.

This means that the two tests won't have an inter-dependency (e.g. if
the earlier test is skipped).

An earlier version of this patch instead asserted that no other test
had any output on stderr. We're not doing that here out of fear that
"gc --auto" or another future change to "git describe" will cause it
to legitimately emit output on stderr unexpectedly[1].

I'd think that inverting the test added in 3291fe4072 (Add
git-describe test for "verify annotated tag names on output",
2008-03-03) to make checking that we don't have warnings the rule
rather than the exception would be the sort of thing the describe
tests should be catching, but for now let's leave it as it is.

we've stripped out the hash-specific g<hash-abbrev>
suffix. 5312ab11fb (Add describe test., 2007-01-13).

This means that we can use test_cmp to compare the output. I could
omit the "-8" change of e.g. "A-*" to "A-8-gHASH", but I think it
makes sense to test that here explicitly. It means you need to add new
tests to the bottom of the file, but that's not a burden in this case.

The "check_describe" being removed here was the earlier test, we then
later added these --work-tree tests which really just wanted to check
if we got the exact same output from "describe", but the test wasn't
structured to test for that.

Let's change it to do that, which both improves test coverage and

52e011cd2b pickaxe -S: support content with NULs under --pickaxe-regex
Fix a bug in the matching routine powering -S<rx> --pickaxe-regex so

It wasn't needed anymore, and as the now-passing test shows, actively
getting in our way. Since we always require REG_STARTEND support we do
not need to stop at NULs. If we are dealing with a haystack with NUL
in it. The needle may be behind that NUL.

2e197a7592 pickaxe: assert that we must have a needle under -G or -S
Assert early in diffcore_pickaxe() that we've got a needle to work
with under -G and -S.

This code is redundant to the check -G and -S get from
parse-options.c's get_arg(), which I'm adding a test for.

This check dates back to e1b161161d (diffcore-pickaxe: fix infinite
loop on zero-length needle, 2007-01-25) when "git log -S" could send
this code into an infinite loop.

It was then later refactored in 8fa4b09fb1 (pickaxe: hoist empty
needle check, 2012-10-28) into its current form, but it seemingly
wasn't noticed that in the meantime a move to the parse-options.c API
in dea007fb4c (diff: parse separate options like -S foo, 2010-08-05)
had made it redundant.

Let's retain some of the paranoia here with a BUG(), but there's no
need to be checking this in the pickaxe_match() inner loop.

188e9e28c5 pickaxe: die when -G and --pickaxe-regex are combined
When the -G and --pickaxe-regex options are combined we simply ignore
the --pickaxe-regex option. Let's die instead as suggested by our
documentation, since -G is always a regex.

When --pickaxe-regex was added in d01d8c6782 (Support for pickaxe
matching regular expressions, 2006-03-29) only the -S option
existed. Then when -G was added in f506b8e8b5 (git log/diff: add
-G<regexp> that greps in the patch text, 2010-08-23) neither the
documentation for --pickaxe-regex was updated accordingly, nor was
something like this assertion added.

Since 5bc3f0b567 (diffcore-pickaxe doc: document -S and -G properly,
2013-05-31) we've claimed that --pickaxe-regex should only be used
with -S, but have silently tolerated combining it with -G, let's die
instead.

7cd5d5b299 pickaxe tests: add missing test for --no-pickaxe-regex being an error
Add a missing test for --no-pickaxe-regex. This has been an error ever
since before the -S or -G options were added, or since
7ae0b0cb65 (git-log (internal): more options., 2006-03-01).

The reason for adding this test is that Junio suggested in [1] in
response to a later test addition in this series that it might be good
to support --no-pickaxe-regex in combination with -G. This would allow
for fixed-string searching with -G, similr to grep's --fixed-strings
mode.

I agree that that would make sense if anyone would like to implement
it, but since it dies right now let's first add this test to assert
the existing long-standing behavior. We can always add support for
--[no-]pickaxe-regex in combination with -G at some later date.

Refactor the existing tests added in e0e7cb8080 (log -G: ignore

in-flight topic of mine this commit depends on.

While I'm at it change some of the setup of the test to use a more
sensible pattern, e.g. setting up a temporary repo instead of creating
an orphan branch.

Since the -G and -S options will behave the same way with truncated
and removed content also change the "git rm" to emptying data.bin,
that's just catering to how test_commit works. The resulting test is
shorter.

f0d4d398e2 test-lib: split up and deprecate test_create_repo()
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 eea420693b (t0000: catch trivial pilot errors.,
    2005-12-10) and 2ccd2027b0 (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
    0d314ce834 (test-lib: use subshell instead of cd $new && .. && cd
    $old, 2010-08-30).

    But since 2006f0adae (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
    3af4c7156c (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 c09a69a83e (Disable hooks during tests.,
    2005-10-16), since then hooks became disabled by default in
    f98f8cbac0 (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 eedf8f97e5 (Abstract
    test_create_repo out for use in tests., 2006-02-17), and later
    "cd"'d inside a subshell since 0d314ce834 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
    8683a45d66 (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

97c8aac9c5 test-lib: do not show advice about init.defaultBranch under --verbose
Arrange for the advice about naming the initial branch not to be shown
in the --verbose output of the test suite.

Since 675704c74d (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 675704c74d 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.

ba7d318504 submodule tests: use symbolic-ref --short to discover branch name
Change a use of $GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME added in
704fed9ea2 (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 704fed9ea2, 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
variable in the test suite, this gets rid of one of those.

47c88d16ba test-lib functions: add --printf option to test_commit
Add a --printf option to test_commit to allow writing to the file with
"printf" instead of "echo".

This is useful for writing "\n", "\0" etc., in particular in
combination with the --append option added in 3373518cc8 (test-lib
functions: add an --append option to test_commit, 2021-01-12).

I'm converting a few tests to use the new option rather than a manual
printf/add/commit combination to demonstrate its usefulness. While I'm
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.

8cfe386b78 describe tests: convert setup to use test_commit
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 5312ab11fb (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.

6cf8d96fa2 test-lib functions: add an --annotated option to "test_commit"
Add an --annotated option to test_commit to create annotated tags. The
tag will share the same message as the commit, and we'll call
test_tick before creating it (unless --notick) is provided.

There's quite a few tests that could be simplified with this
construct. I've picked one to convert in this change as a
demonstration.

edc23840b0 test-lib: bring $remove_trash out of retirement
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 df4c0d1a79 (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

In previous changes, we've turned on warning for quoted CR in base64 or

they know that it happens most of the time, and they find it's desirable
to always strip those CR.

Those projects in question usually fall back to use other tools to handle
patches when receive such patches.

Let's help those projects handle those patches by stripping those
excessive CR.

0b689562ca mailinfo: warn if CRLF found in decoded base64/QP email
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.
