This option allows commits with empty commit messages to be rebased,
matching the same option in git-commit and git-cherry-pick. While empty
log messages are frowned upon, sometimes one finds them in older
repositories (e.g. translated from another VCS [0]), or have other
reasons for desiring them. The option is available in git-commit and
git-cherry-pick, so it is natural to make other git tools play nicely
with them. Adding this as an option allows the default to be "give the
user a chance to fix", while not interrupting the user's workflow
otherwise [1].

There has never been any full roundtrip testing of what git-ls-files
and other commands that use wildmatch() actually do, rather we've been
satisfied with just testing the underlying C function.
Due to git-ls-files and friends having their own codepaths before they
call wildmatch() there's sometimes differences in the behavior between
the two. Even when we test for those (as with [1]), there was no one
place where you can review how these two modes differ.
Now there is. We now attempt to create a file called $haystack and
match $needle against it for each pair of $needle and $haystack that
we were passing to test-wildmatch.
If we can't create the file we skip the test. This ensures that we can
run this on all platforms and not maintain some infinitely growing
whitelist of e.g. platforms that don't support certain characters in
filenames.
A notable exception to this is Windows, where due to the reasons
explained in [2] the shellscript emulation layer might fake the
creation of a file such as "*", and "test -e" for it will succeed
since it just got created with some character that maps to "*", but
git ls-files won't be fooled by this.
Thus we need to skip creating certain filenames entirely on Windows,
the list here might be overly aggressive. I don't have access to a
Windows system to test this.
As a result of doing these tests we can now see the cases where these
two ways of testing wildmatch differ:
* Creating a file called 'a[]b' and running ls-files 'a[]b' will show
that file, but wildmatch("a[]b", "a[]b") will not match
* wildmatch() won't match a file called \ against \, but ls-files
will.
* `git --glob-pathspecs ls-files 'foo**'` will match a file
'foo/bba/arr', but wildmatch won't, however pathmatch will.
This seems like a bug to me, the two are otherwise equivalent as
these tests show.
This also reveals the case discussed in [1], since 2.16.0 '' is now an
error as far as ls-files is concerned, but wildmatch() itself happily
accepts it.

Rewrite the wildmatch() test suite so that each test now tests all
combinations of the wildmatch() WM_CASEFOLD and WM_PATHNAME flags.
Before this change some test inputs were not tested on
e.g. WM_PATHNAME. Now the function is stress tested on all possible
inputs, and for each input we declare what the result should be if the
mode is case-insensitive, or pathname matching, or case-sensitive or
not matching pathnames.
Also before this change, nothing was testing case-insensitive
non-pathname matching, so I've added that to test-wildmatch.c and made
use of it.
This yields a rather scary patch, but there are no functional changes
here, just more test coverage. Some now-redundant tests were deleted
as a result of this change, since they were now duplicating an earlier

When git-daemon gets a pktline request, we strip off any
trailing newline, replacing it with a NUL. Clients prior to
5ad312bede (in git v1.4.0) would send:
git-upload-pack repo.git\n
and we need to strip it off to understand their request.
After 5ad312bede, we send the host attribute but no newline,
like:
git-upload-pack repo.git\0host=example.com\0
Both of these are parsed correctly by git-daemon. But if
some client were to combine the two:
git-upload-pack repo.git\n\0host=example.com\0
we don't parse it correctly. The problem is that we use the
"len" variable to record the position of the NUL separator,
but then decrement it when we strip the newline. So we start
with:
git-upload-pack repo.git\n\0host=example.com\0
^-- len
and end up with:
git-upload-pack repo.git\0\0host=example.com\0
^-- len
This is arguably correct, since "len" tells us the length of
the initial string, but we don't actually use it for that.
What we do use it for is finding the offset of the extended
attributes; they used to be at len+1, but are now at len+2.
We can solve that by just leaving "len" where it is. We
don't have to care about the length of the shortened string,
since we just treat it like a C string.
No version of Git ever produced such a string, but it seems
like the daemon code meant to handle this case (and it seems
like a reasonable thing for somebody to do in a 3rd-party
implementation).

All of our git-protocol tests rely on invoking the client
and having it make a request of a server. That gives a nice
real-world test of how the two behave together, but it
doesn't leave any room for testing how a server might react
to _other_ clients.
Let's add a few test helper functions which can be used to
manually conduct a git-protocol conversation with a remote
git-daemon:
1. To connect to a remote git-daemon, we need something
like "netcat". But not everybody will have netcat. And
even if they do, the behavior with respect to
half-duplex shutdowns is not portable (openbsd netcat
has "-N", with others you must rely on "-q 1", which is
racy).
Here we provide a "fake_nc" that is capable of doing
a client-side netcat, with sane half-duplex semantics.
It relies on perl's IO::Socket::INET. That's been in
the base distribution since 5.6.0, so it's probably
available everywhere. But just to be on the safe side,
we'll add a prereq.
2. To help tests speak and read pktline, this patch adds
packetize() and depacketize() functions.
I've put fake_nc() into lib-git-daemon.sh, since that's
really the only server where we'd need to use a network
socket. Whereas the pktline helpers may be of more general
use, so I've added them to test-lib-functions.sh. Programs
like upload-pack speak pktline, but can talk directly over
stdio without a network socket.

If we receive a request with extended attributes after the
NUL, we try to write those attributes to the log. We do so
with a "%s" format specifier, which will only show
characters up to the first NUL.
That's enough for printing a "host=" specifier. But since
dfe422d04d (daemon: recognize hidden request arguments,
2017-10-16) we may have another NUL, followed by protocol
parameters, and those are not logged at all.
Let's cut out the attempt to show the whole string, and
instead log when we parse individual attributes. We could
leave the "extended attributes (%d bytes) exist" part of the
log, which in theory could alert us to attributes that fail
to parse. But anything we don't parse as a "host=" parameter
gets blindly added to the "protocol" attribute, so we'd see
it in that part of the log.

If receive a request like:
git-upload-pack /foo.git\0host=localhost
we mark the offset of the NUL byte as "len", and then log
the bytes after the NUL with a "%.*s" placeholder, using
"pktlen - len" as the length, and "line + len + 1" as the
start of the string.
This is off-by-one, since the start of the string skips past
the separating NUL byte, but the adjusted length includes
it. Fortunately this doesn't actually read past the end of
the buffer, since "%.*s" will stop when it hits a NUL. And
regardless of what is in the buffer, packet_read() will
always add an extra NUL terminator for safety.
As an aside, the git.git client sends an extra NUL after a
"host" field, too, so we'd generally hit that one first, not
the one added by packet_read(). You can see this in the test
output which reports 15 bytes, even though the string has
only 14 bytes of visible data. But the point is that even a
client sending unusual data could not get us to read past
the end of the buffer, so this is purely a cosmetic fix.

When we start git-daemon for our tests, we send its stderr
log stream to a named pipe. We synchronously read the first
line to make sure that the daemon started, and then dump the
rest to descriptor 4. This is handy for debugging test
output with "--verbose", but the tests themselves can't
access the log data.
Let's dump the log into a file, as well, so that future
tests can check the log. There are a few subtleties worth
calling out here:
- we'll continue to send output to descriptor 4 for
viewing/debugging, which would imply swapping out "cat"
for "tee". But we want to ensure that there's no
buffering, and "tee" doesn't have a standard way to
ask for that. So we'll use a shell loop around "read"
and "printf" instead. That ensures that after a request
has been served, the matching log entries will have made
it to the file.
- the existing first-line shell loop used read/echo. We'll
switch to consistently using "read -r" and "printf" to
relay data as faithfully as possible.
- we open the logfile for append, rather than just output.
That makes it OK for tests to truncate the logfile
without restarting the daemon (the OS will atomically
seek to the end of the file when outputting each line).
That allows tests to look at the log without worrying
about pollution from earlier tests.

Let's start with how create a new directory cache after the last one
becomes invalid (e.g. because its dir mtime has changed...). In
open_cached_dir():
1. We start out with valid_cached_dir() returning false, which should
call invalidate_directory() to put a directory state back to
initial state, no untracked entries (untracked_nr zero), no sub
directory traversal (dirs[].recurse zero).
2. Since the cache cannot be used, we go the slow path opendir() and
go through items one by one via readdir(). All the directories on
disk will be added back to the cache (if not already exist in
dirs[]) and its flag "recurse" gets changed to one to note that
it's part of the cached dir travesal next time.
3. By the time we reach close_cached_dir() we should have a good
subdir list in dirs[]. Those with "recurse" flag set are the ones
present in the on-disk directory. The directory is now marked
"valid".
Next time read_directory() is called, since the directory is marked
valid, it will skip readdir(), go fast path and traverse through
dirs[] array instead.
Steps one and two need some tight cooperation. If a subdir is removed,
readdir() will not find it and of course we cannot examine/invalidate
it. To make sure removed directories on disk are gone from the cache,
step one must make sure recurse flag of all subdirs are zero.
But that's not true. If "valid" flag is already false, there is a
chance we go straight to the end of valid_cached_dir() without calling
invalidate_directory(). Or we fail to meet the "if (untracked-valid)"
condition and skip over the invalidate_directory().
After step 3, we mark the cache valid. Any stale subdir with incorrect
recurse flag becomes a real subdir next time we traverse the directory
using dirs[] array.
We could avoid this by making sure invalidate_directory() is always
called (therefore dirs[].recurse cleared) at the beginning of
open_cached_dir(). Which is what this patch does.
As to how we get into this situation, the key in the test is this
command
git checkout master
where "one/file" is replaced with "one" in the index. This index
update triggers untracked_cache_invalidate_path(), which clears valid
flag of the root directory while keeping "recurse" flag on the subdir
"one" on. On the next git-status, we go through steps 1-3 above and
save an incorrect cache on disk. The second git-status blindly follows
the bad cache data and shows the problem.
This is arguably because of a bad design where "recurse" flag plays
double roles: whether a directory should be saved on disk, and whether
it is part of a directory traversal.
We need to keep recurse flag set at "checkout master" because of the
first role: we need to keep subdir caches (dir "two" for example has
not been touched at all, no reason to throw its cache away).
As long as we make sure to ignore/reset "recurse" flag at the
beginning of a directory traversal, we're good. But maybe eventually
we should separate these two roles.

The untracked cache gets confused when a directory is swapped out for
a file. It is easiest to reproduce this by swapping out a directory
with a symlink to another directory, and as the tests show the symlink
case is the only case we've found where "git status" will subsequently
report incorrect information, even though it's possible to otherwise
get the untracked cache into a state where its internal data
structures don't reflect reality.
In the symlink case, whatever files are inside the target of the
symlink will be incorrectly shown as untracked. This issue does not
happen if the symlink links to another file, only if it links to
another directory.
A stand-alone testcase for copying into a terminal:
(
rm -rf /tmp/testrepo &&
git init /tmp/testrepo &&
cd /tmp/testrepo &&
mkdir x y &&
touch x/a y/b &&
git add x/a y/b &&
git commit -msnap &&
git rm -rf y &&
ln -s x y &&
git add y &&
git commit -msnap2 &&
git checkout HEAD~ &&
git status &&
git checkout master &&
sleep 1 &&
git status &&
git status
)
This will incorrectly show y/a as an untracked file. Both the "git
status" call right before "git checkout master" and the "sleep 1"
after the "checkout master" are needed to reproduce this, presumably
due to the untracked cache tracking on the basis of cached whole
seconds from stat(2).
When git gets into this state, a workaround to fix it is to issue a
one-off:
git -c core.untrackedCache=false status
For the non-symlink case, the bug is that the output of
test-dump-untracked-cache should not include:
/one/ 0000000000000000000000000000000000000000 recurse valid
It being in the output implies that cached traversal of root includes
the directory "one" which does not exist on disk anymore.

Check that cherry-pick and rebase call the 'prepare-commit-msg' hook
correctly. The expected values for the hook arguments are taken to
match the current master branch. I think there is scope for improving
the arguments passed so they make a bit more sense - for instance
cherry-pick currently passes different arguments depending on whether
the commit message is being edited. Also the arguments for rebase
could be improved. Commit 7c4188360a ("rebase -i: proper
prepare-commit-msg hook argument when squashing", 2008-10-3) apparently
changed things so that when squashing rebase would pass 'squash' as
the argument to the hook but that has been lost.
I think that it would make more sense to pass 'message' for revert and
cherry-pick -x/-s (i.e. cases where there is a new message or the
current message in modified by the command), 'squash' when squashing
with a new message and 'commit HEAD/CHERRY_PICK_HEAD'
otherwise (picking and squashing without a new message).

index, even if the shared index can not be written.
We did so by just calling 'do_write_locked_index()' just before
'write_shared_index()'. 'do_write_locked_index()' always at least
closes the tempfile nowadays, and used to close or commit the lockfile
if COMMIT_LOCK or CLOSE_LOCK were given at the time this feature was
introduced. COMMIT_LOCK or CLOSE_LOCK is passed in by most callers of
'write_locked_index()'.
After calling 'write_shared_index()', we call 'write_split_index()',
which calls 'do_write_locked_index()' again, which then tries to use the
closed lockfile again, but in fact fails to do so as it's already
closed. This eventually leads to a segfault.
Make sure to write the main index only once.

t3501 had a testcase originally added in 05f2dfb965 (cherry-pick:
demonstrate a segmentation fault, 2016-11-26) to ensure cherry-pick
wouldn't segfault when working with a dirty file involved in a rename.
While the segfault was fixed, there was another problem this test
demonstrated: namely, that git would overwrite a dirty file involved in a
rename. Further, the test encoded a "successful merge" and overwriting of
this file as correct behavior. Modify the test so that it would still
catch the segfault, but to require the correct behavior. Mark it as
test_expect_failure for now too, since this second bug is not yet fixed.
t7607 had a test added in 30fd3a5425 (merge overwrites unstaged changes in
renamed file, 2012-04-15) specific to looking for a merge overwriting a
dirty file involved in a rename, but it too actually encoded what I would
term incorrect behavior: it expected the merge to succeed. Fix that, and
add a few more checks to make sure that the merge really does produce the
expected results.

In a96d3cc3f6 ("cache-tree: reject entries with null sha1", 2017-04-21)
we made sure that broken cache entries do not get propagated to new
trees. Part of that was making sure not to re-use an existing cache
tree that includes a null oid.
It did so by dropping the cache tree in 'do_write_index()' if one of
the entries contains a null oid. In split index mode however, there
are two invocations to 'do_write_index()', one for the shared index
and one for the split index. The cache tree is only written once, to
the split index.
As we only loop through the elements that are effectively being
written by the current invocation, that may not include the entry with
a null oid in the split index (when it is already written to the
shared index), where we write the cache tree. Therefore in split
index mode we may still end up writing the cache tree, even though
there is an entry with a null oid in the index.
Fix this by checking for null oids in prepare_to_write_split_index,
where we loop the entries of the shared index as well as the entries for
the split index.
This fixes t7009 with GIT_TEST_SPLIT_INDEX. Also add a new test that's
more specifically showing the problem.

For 'add -i' and 'add -p', the only action we can take on a dirty
submodule entry is update the index with a new value from its HEAD. The
content changes inside (from its own index, untracked files...) do not
matter, at least until 'git add -i' learns about launching a new
interactive add session inside a submodule.
Ignore all other submodules changes except HEAD. This reduces the number
of entries the user has to check through in 'git add -i', and the number
of 'no' they have to answer to 'git add -p' when dirty submodules are
present.

Git's assumption that all path lists are colon-separated is not only
wrong on Windows, it is not even an assumption that is compatible with
POSIX.
In the interest of time, let's not try to fix this properly but simply
work around the obvious breakage on Windows, where the MSYS2 Bash used
by Git for Windows to interpret the Git's Unix shell scripts will
automagically convert path lists in the environment to
semicolon-separated lists of Windows paths (with drive letter and the
corresponding colon and all that jazz).
In other words, we simply look whether there is a semicolon in
GITPERLLIB and split by semicolons if found instead of colons. This is
not fool-proof, of course, as the path list could consist of a single
path. But that is not the case in Git for Windows' test suite, there are
always two paths in GITPERLLIB.

When merging another branch into ours, if their tree is the same as
the common ancestor's, we can declare that our tree represents the
result of three-way merge. In such a case, the recursive merge
backend incorrectly used to create a commit out of our index, even
when the index has changes.
A recent fix attempted to prevent this by adding a comparison
between "our" tree and the index, but forgot that this check must be
restricted only to the outermost merge. Inner merges performed by
the recursive backend across merge bases are by definition made from
scratch without having any local changes added to the index. The
call to index_has_changes() during an inner merge is working on the
index that has no relation to the merge being performed, preventing
legitimate merges from getting carried out.
Fix it by limiting the check to the outermost merge.

Currently when 'git stash push -- <pathspec>' is used, untracked files
that match the pathspec will be deleted, even though they do not end up
in a stash anywhere.
This is because the original commit introducing the pathspec feature in
git stash push (df6bba0937 ("stash: teach 'push' (and 'create_stash') to
honor pathspec", 2017-02-28)) used the sequence of 'git reset <pathspec>
&& git ls-files --modified <pathspec> | git checkout-index && git clean
<pathspec>'.
The intention was to emulate what 'git reset --hard -- <pathspec>' would
do. The call to 'git clean' was supposed to clean up the files that
were unstaged by 'git reset'. This would work fine if the pathspec
doesn't match any files that were untracked before 'git stash push --
<pathspec>'. However if <pathspec> matches a file that was untracked
before invoking the 'stash' command, all untracked files matching the
pathspec would inadvertently be deleted as well, even though they
wouldn't end up in the stash, and are therefore lost.
This behaviour was never what was intended, only blobs that also end up
in the stash should be reset to their state in HEAD, previously
untracked files should be left alone.
To achieve this, first match what's in the index and what's in the
working tree by adding all changes to the index, ask diff-index what
changed between HEAD and the current index, and then apply that patch in
reverse to get rid of the changes, which includes removal of added
files and resurrection of removed files.

Sometimes users are given a hash of an object and they want to
identify it further (ex.: Use verify-pack to find the largest blobs,
but what are these? or [1])
One might be tempted to extend git-describe to also work with blobs,
such that `git describe <blob-id>` gives a description as
'<commit-ish>:<path>'. This was implemented at [2]; as seen by the sheer
number of responses (>110), it turns out this is tricky to get right.
The hard part to get right is picking the correct 'commit-ish' as that
could be the commit that (re-)introduced the blob or the blob that
removed the blob; the blob could exist in different branches.
Junio hinted at a different approach of solving this problem, which this
patch implements. Teach the diff machinery another flag for restricting
the information to what is shown. For example:
$ ./git log --oneline --find-object=v2.0.0:Makefile
b2feb64309 Revert the whole "ask curl-config" topic for now
47fbfded53 i18n: only extract comments marked with "TRANSLATORS:"
we observe that the Makefile as shipped with 2.0 was appeared in
v1.9.2-471-g47fbfded53 and in v2.0.0-rc1-5-gb2feb6430b. The
reason why these commits both occur prior to v2.0.0 are evil
merges that are not found using this new mechanism.

When cleaning up files in the $HOME directory, it really makes sense to
quote the path, especially in Git's test suite, where the HOME directory
is *guaranteed* to contain spaces in its name.
It would appear that those two tests pass even without cleaning up the
files, but really more by pure chance than by design (the cleanup seems
not actually to be necessary).
However, if anybody would have a left-over `trash/` directory in Git's
`t/` directory, these tests would fail, because they would all of a

Once upon a time, git-clone would refuse to write into a
directory that it did not itself create. The cleanup
routines for a failed clone could therefore just remove the
git and worktree dirs completely.
In 55892d2398 (Allow cloning to an existing empty directory,
2009-01-11), we learned to write into an existing directory.
Which means that doing:
mkdir foo
git clone will-fail foo
ends up deleting foo. This isn't a huge catastrophe, since
by definition foo must be empty. But it's somewhat
confusing; we should leave the filesystem as we found it.
Because we know that the only directory we'll write into is
an empty one, we can handle this case by just passing the
KEEP_TOPLEVEL flag to our recursive delete (if we could
write into populated directories, we'd have to keep track of
what we wrote and what we did not, which would be much
harder).
Note that we need to handle the work-tree and git-dir
separately, though, as only one might exist (and the new
tests in t5600 cover all cases).

The man page of the "git describe" command explains the expected
output when using the --all option, i.e. the full reference path is
shown, including heads/ or tags/ prefix.
When 212945d4a8 ("Teach git-describe
to verify annotated tag names before output") made Git favor the
embedded name of annotated tags, it accidentally changed the output
format when the --all flag is given, only printing the tag's name
without the prefix.
Check if --all was specified and re-add the "tags/" prefix for this
special case to fix the regresssion.

The gpg_sign member of the replay_opts structure is of type `char *`,
meaning that the sequencer deems the string to which gpg_sign points to

--update-shelve can now be specified multiple times on the
command-line, to update multiple shelved changelists in a single
submit.
This then means that a git patch series can be mirrored to a
sequence of shelved changelists, and (relatively easily) kept in
sync as changes are made in git.
Note that Perforce does not really support overlapping shelved
changelists where one change touches the files modified by
another. Trying to do this will result in merge conflicts.

Add support for supplying the -m option with --fixup. Doing so has
errored out ever since --fixup was introduced. Before this, the only
way to amend the fixup message while committing was to use --edit and
amend it in the editor.
The use-case for this feature is one of:
* Leaving a quick note to self when creating a --fixup commit when
it's not self-evident why the commit should be squashed without a
note into another one.
* (Ab)using the --fixup feature to "fix up" commits that have already
been pushed to a branch that doesn't allow non-fast-forwards,
i.e. just noting "this should have been part of that other commit",
and if the history ever got rewritten in the future the two should
be combined.
In such a case you might want to leave a small message,
e.g. "forgot this part, which broke XYZ".
With this, --fixup <commit> -m"More" -m"Details" will result in a
commit message like:
!fixup <subject of <commit>>
More
Details
The reason the test being added here seems to squash "More" at the end
of the subject line of the commit being fixed up is because the test
code is using "%s%b" so the body immediately follows the subject, it's
not a bug in this code, and other tests t7500-commit.sh do the same
thing.
When the --fixup option was initially added the "Option -m cannot be
combined" error was expanded from -c, -C and -F to also include
--fixup[1]
Those options could also support combining with -m, but given what
they do I can't think of a good use-case for doing that, so I have not
made the more invasive change of splitting up the logic in commit.c to
first act on those, and then on -m options.

Test scripts count number of lines in an output and check it againt
its expectation. fb3340a6 ("test-lib: introduce test_line_count to

such a test in a more readable way than comparing `wc -l` output with
a number.
Besides, on some platforms, "$(wc -l <file)" is padded with leading
whitespace on the left, so
test "$(wc -l <file)" = 4

* ew/empty-merge-with-dirty-index-maint:
merge-recursive: avoid incorporating uncommitted changes in a merge
move index_has_changes() from builtin/am.c to merge.c for reuse
t6044: recursive can silently incorporate dirty changes in a merge
builtin/merge.c contains this important requirement for merge strategies:
/*
* At this point, we need a real merge. No matter what strategy
* we use, it would operate on the index, possibly affecting the
* working tree, and when resolved cleanly, have the desired
* tree in the index -- this means that the index must be in

* to ensure this.
*/
merge-recursive does not do this check directly, instead it relies on
unpack_trees() to do it. However, merge_trees() has a special check for
the merge branch exactly matching the merge base; when it detects that
situation, it returns early without calling unpack_trees(), because it
knows that the HEAD commit already has the correct result. Unfortunately,
it didn't check that the index matched HEAD, so after it returned, the
outer logic ended up creating a merge commit that included something
other than HEAD.

Sometimes users are given a hash of an object and they want to
identify it further (ex.: Use verify-pack to find the largest blobs,
but what are these? or [1])
When describing commits, we try to anchor them to tags or refs, as these
are conceptually on a higher level than the commit. And if there is no ref
or tag that matches exactly, we're out of luck. So we employ a heuristic
to make up a name for the commit. These names are ambiguous, there might
be different tags or refs to anchor to, and there might be different
path in the DAG to travel to arrive at the commit precisely.
When describing a blob, we want to describe the blob from a higher layer
as well, which is a tuple of (commit, deep/path) as the tree objects
involved are rather uninteresting. The same blob can be referenced by
multiple commits, so how we decide which commit to use? This patch
implements a rather naive approach on this: As there are no back pointers
from blobs to commits in which the blob occurs, we'll start walking from
any tips available, listing the blobs in-order of the commit and once we
found the blob, we'll take the first commit that listed the blob. For
example
git describe --tags v0.99:Makefile
conversion-901-g7672db20c2:Makefile
tells us the Makefile as it was in v0.99 was introduced in commit 7672db20.
The walking is performed in reverse order to show the introduction of a
blob rather than its last occurrence.

Setting SVNSERVE_PORT enables several tests which require a local

`--listen-once` option, which causes svnserve to accept one connection
on the port, serve it, and exit. When running the tests in parallel
this fails if one test tries to start svnserve while the other is still
running.

When worktree functionality was originally implemented, the possibility
of 'clone --local' from within a worktree was overlooked, with the
result that the location of the "objects" directory of the source
repository was computed incorrectly, thus the objects could not be
copied or hard-linked by the clone. This shortcoming was addressed by
744e469755 (clone: allow --local from a linked checkout, 2015-09-28).
However, the related case of 'clone --shared' (despite being handled
only a few lines away from the 'clone --local' case) was not fixed by
744e469755, with a similar result of the "objects" directory location
being incorrectly computed for insertion into the 'alternates' file.

Replace the perl/Makefile.PL and the fallback perl/Makefile used under
NO_PERL_MAKEMAKER=NoThanks with a much simpler implementation heavily
inspired by how the i18n infrastructure's build process works[1].
The reason for having the Makefile.PL in the first place is that it
was initially[2] building a perl C binding to interface with libgit,
this functionality, that was removed[3] before Git.pm ever made it to
the master branch.
We've since since started maintaining a fallback perl/Makefile, as
MakeMaker wouldn't work on some platforms[4]. That's just the tip of
the iceberg. We have the PM.stamp hack in the top-level Makefile[5] to
detect whether we need to regenerate the perl/perl.mak, which I fixed
just recently to deal with issues like the perl version changing from
under us[6].
There is absolutely no reason for why this needs to be so complex
anymore. All we're getting out of this elaborate Rube Goldberg machine
was copying perl/* to perl/blib/* as we do a string-replacement on
the *.pm files to hardcode @@LOCALEDIR@@ in the source, as well as
pod2man-ing Git.pm & friends.
So replace the whole thing with something that's pretty much a copy of
how we generate po/build/**.mo from po/*.po, just with a small sed(1)
command instead of msgfmt. As that's being done rename the files
from *.pm to *.pmc just to indicate that they're generated (see
"perldoc -f require").
While I'm at it, change the fallback for Error.pm from being something
where we'll ship our own Error.pm if one doesn't exist at build time
to one where we just use a Git::Error wrapper that'll always prefer
the system-wide Error.pm, only falling back to our own copy if it
really doesn't exist at runtime. It's now shipped as
Git::FromCPAN::Error, making it easy to add other modules to
Git::FromCPAN::* in the future if that's needed.
Functional changes:
* This will not always install into perl's idea of its global
"installsitelib". This only potentially matters for packagers that
need to expose Git.pm for non-git use, and as explained in the
INSTALL file there's a trivial workaround.
* The scripts themselves will 'use lib' the target directory, but if
INSTLIBDIR is set it overrides it. It doesn't have to be this way,
it could be set in addition to INSTLIBDIR, but my reading of [7] is
that this is the desired behavior.
* We don't build man pages for all of the perl modules as we used to,
only Git(3pm). As discussed on-list[8] that we were building
installed manpages for purely internal APIs like Git::I18N or
private-Error.pm was always a bug anyway, and all the Git::SVN::*
ones say they're internal APIs.
There are apparently external users of Git.pm, but I don't expect
there to be any of the others.
As a side-effect of these general changes the perl documentation
now only installed by install-{doc,man}, not a mere "install" as
before.

When running checkout, first prefetch all blobs that are to be updated
but are missing. This means that only one pack is downloaded during such
operations, instead of one per missing blob.
This operates only on the blob level - if a repository has a missing
tree, they are still fetched one at a time.
This does not use the delayed checkout mechanism introduced in commit
2841e8f ("convert: add "status=delayed" to filter process protocol",
2017-06-30) due to significant conceptual differences - in particular,
for partial clones, we already know what needs to be fetched based on
the contents of the local repo alone, whereas for status=delayed, it is
the filter process that tells us what needs to be checked in the end.

For efficiency, if an object is referenced by a promisor object, and is

not stop there. This is to avoid building the list of promisor object
references.
(In list-objects.c, the case where obj is NULL in process_blob() and

Teach sha1_file to fetch objects from the remote configured in
extensions.partialclone whenever an object is requested but missing.
The fetching of objects can be suppressed through a global variable.
This is used by fsck and index-pack.
However, by default, such fetching is not suppressed. This is meant as a
temporary measure to ensure that all Git commands work in such a
situation. Future patches will update some commands to either tolerate
missing objects (without fetching them) or be more efficient in fetching
them.
In order to determine the code changes in sha1_file.c necessary, I
investigated the following:
(1) functions in sha1_file.c that take in a hash, without the user
regarding how the object is stored (loose or packed)
(2) functions in packfile.c (because I need to check callers that know
about the loose/packed distinction and operate on both differently,
and ensure that they can handle the concept of objects that are
neither loose nor packed)
(1) is handled by the modification to sha1_object_info_extended().
For (2), I looked at for_each_packed_object and others. For
for_each_packed_object, the callers either already work or are fixed in
this patch:
- reachable - only to find recent objects
- builtin/fsck - already knows about missing objects
- builtin/cat-file - warning message added in this commit
Callers of the other functions do not need to be changed:
- parse_pack_index
- http - indirectly from http_get_info_packs
- find_pack_entry_one
- this searches a single pack that is provided as an argument; the
caller already knows (through other means) that the sought object
is in a specific pack
- find_sha1_pack
- fast-import - appears to be an optimization to not store a file if
it is already in a pack
- http-walker - to search through a struct alt_base
- http-push - to search through remote packs
- has_sha1_pack
- builtin/fsck - already knows about promisor objects
- builtin/count-objects - informational purposes only (check if loose
object is also packed)
- builtin/prune-packed - check if object to be pruned is packed (if
not, don't prune it)
- revision - used to exclude packed objects if requested by user
- diff - just for optimization

You may want to run the test suite with a different shell
than you use to build Git. For instance, you may build with
SHELL_PATH=/bin/sh (because it's faster, or it's what you
expect to exist on systems where the build will be used) but
want to run the test suite with bash (e.g., since that
allows using "-x" reliably across the whole test suite).
There's currently no good way to do this.
You might think that doing two separate make invocations,
like:
make &&
make -C t SHELL_PATH=/bin/bash
would work. And it _almost_ does. The second make will see
our bash SHELL_PATH, and we'll use that to run the
individual test scripts (or tell prove to use it to do so).
So far so good.
But this breaks down when "--tee" or "--verbose-log" is
used. Those options cause the test script to actually
re-exec itself using $SHELL_PATH. But wait, wouldn't our
second make invocation have set SHELL_PATH correctly in the
environment?
Yes, but test-lib.sh sources GIT-BUILD-OPTIONS, which we
built during the first "make". And that overrides the
environment, giving us the original SHELL_PATH again.
Let's introduce a new variable that lets you specify a
specific shell to be run for the test scripts. Note that we
have to touch both the main and t/ Makefiles, since we have
to record it in GIT-BUILD-OPTIONS in one, and use it in the
latter.

The "-x" tracing option implies "--verbose". This is a
problem when running under a TAP harness like "prove", where
we need to use "--verbose-log" instead. Instead, let's
handle this the same way we do for --valgrind, including the
recent fix from 88c6e9d31c (test-lib: --valgrind should not
override --verbose-log, 2017-09-05). Namely, let's enable
--verbose only when we know there isn't a more specific
verbosity option indicated.
Note that we also have to tweak `want_trace` to turn it on
(previously we just lumped $verbose_log in with $verbose,
but now we don't necessarily auto-set the latter).
