Compiled test helpers in t/helper are out of sync with the .gitignore
files quite frequently. This can happen when new test helpers are added,
but the explicit .gitignore file is not updated in the same commit, or
when you forget to 'make clean' before checking out a different version
of git, as the different version may have a different explicit list of
test helpers to ignore.
Fix this by having an overly broad ignore pattern in that directory:
Anything, except C and shell source, will be ignored.

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.

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).

File descriptors 3 and 4 are special in our test suite, as
they link back to the test script's original stdout and
stderr. Normally this isn't something tests need to worry
about: they are free to clobber these descriptors for
sub-commands without affecting the overall script.
But there's one very special thing about descriptor 4: since
d88785e424 (test-lib: set BASH_XTRACEFD automatically,
2016-05-11), we ask bash to output "set -x" output to it by
number. This goes to _any_ descriptor 4, even if it no
longer points to the place it did when we set BASH_XTRACEFD.
But in t5615, we run a shell loop with descriptor 4
redirected. As a result, t5615 works with non-bash shells
even with "-x". And it works with bash without "-x". But the
combination of "bash t5615-alternate-env.sh -x" gets a test
failure (because our "set -x" output pollutes one of the
files).
We can fix this by using any descriptor _except_ the magical
4. So let's switch arbitrarily to using 5/6 in this loop,
not 3/4.
Another alternative is to use a different descriptor for
BASH_XTRACEFD. But picking an unused one turns out to be
hard. Most shells limit us to 9 numbered descriptors. Bash
can handle more, but:
- while the BASH_XTRACEFD is specific to bash, GIT_TRACE=4
has a similar problem, and would affect all shells
- constructs like "999>/dev/null" are synticatically
invalid to non-bash shells. So we have to actually bury
it inside an eval, which creates more complications.
Of the numbers 1-9, you might think that "9" would be less
used than "4". But it's not; many of our scripts use
descriptors 8 and 9 (probably under the assumption that they
are high and therefore unused). The least-used descriptor is
currently "7". We could switch to that, but we're just
trading one magic number for another.

When the test suite's "-x" option is used with bash, we end
up seeing cleanup cruft in the output:
$ bash t0001-init.sh -x
[...]
++ diff -u expected actual
+ test_eval_ret_=0
+ want_trace
+ test t = t
+ test t = t
+ set +x
ok 42 - re-init from a linked worktree
This ranges from mildly annoying (for a successful test) to
downright confusing (when we say "last command exited with
error", but it's really 5 commands back).
We normally are able to suppress this cleanup. As the
in-code comment explains, we can't convince the shell not to
print it, but we can redirect its stderr elsewhere.
But since d88785e424 (test-lib: set BASH_XTRACEFD
automatically, 2016-05-11), that doesn't hold for bash. It
sends the "set -x" output directly to descriptor 4, not to
stderr.
We can fix this by also redirecting descriptor 4, and
paying close attention to which commands redirected and
which are not (see the updated comment).
Two alternatives I considered and rejected:
- unsetting and setting BASH_XTRACEFD; doing so closes the
descriptor, which we must avoid
- we could keep everything in a single block as before,
redirect 4>/dev/null there, but retain 5>&4 as a copy.
And then selectively restore 4>&5 for commands which
should be allowed to trace. This would work, but the
descriptor swapping seems unnecessarily confusing.

git-clone and git-checkout both invoke the post-checkout hook following
a successful checkout, yet git-worktree neglects to do so even though it
too "checks out" the worktree. Fix this oversight.
Implementation note: The newly-created worktree may reference a branch
or be detached. In the latter case, a commit lookup is performed, though
the result is used only in a boolean sense to (a) determine if the
commit actually exists, and (b) assign either the branch name or commit
ID to HEAD. Since the post-commit hook needs to know the ID of the
checked-out commit, the lookup now needs to be done in all cases, rather
than only when detached. Consequently, a new boolean is needed to handle
(b) since the lookup result itself can no longer perform that role.

A regression was introduced in 557a5998d (submodule: remove
gitmodules_config, 2017-08-03) to how attribute processing was handled
in bare repositories when running the diff-tree command.
By default the attribute system will first try to read ".gitattribute"
files from the working tree and then falls back to reading them from the
index if there isn't a copy checked out in the worktree. Prior to
557a5998d the index was read as a side effect of the call to
'gitmodules_config()' which ensured that the index was already populated
before entering the attribute subsystem.
Since the call to 'gitmodules_config()' was removed the index is no
longer being read so when the attribute system tries to read from the
in-memory index it doesn't find any ".gitattribute" entries effectively
ignoring any configured attributes.
Fix this by explicitly reading the index during the setup of diff-tree.

Commit 74ed43711f (grep: enable recurse-submodules to work on <tree>
objects, 2016-12-16) taught 'tree_entry_interesting()' to be able to
match across submodule boundaries in the presence of wildcards. This is
done by performing literal matching up to the first wildcard and then
punting to the submodule itself to perform more accurate pattern
matching. Instead of introducing a new flag to request this behavior,
commit 74ed43711f overloaded the already existing 'recursive' flag in
'struct pathspec' to request this behavior.
This leads to a bug where whenever any other caller has the 'recursive'
flag set as well as a pathspec with wildcards that all submodules will
be indicated as matches. One simple example of this is:
git init repo
cd repo
git init submodule
git -C submodule commit -m initial --allow-empty
touch "[bracket]"
git add "[bracket]"
git commit -m bracket
git add submodule
git commit -m submodule
git rev-list HEAD -- "[bracket]"
Fix this by introducing the new flag 'recurse_submodules' in 'struct
pathspec' and using this flag to determine if matches should be allowed
to cross submodule boundaries.

Replace use of strbuf_addf() with strbuf_add() when enumerating
loose objects in for_each_file_in_obj_subdir(). Since we already
check the length and hex-values of the string before consuming
the path, we can prevent extra computation by using the lower-
level method.
One consumer of for_each_file_in_obj_subdir() is the abbreviation
code. OID abbreviations use a cached list of loose objects (per
object subdirectory) to make repeated queries fast, but there is
significant cache load time when there are many loose objects.
Most repositories do not have many loose objects before repacking,
but in the GVFS case the repos can grow to have millions of loose
objects. Profiling 'git log' performance in GitForWindows on a
GVFS-enabled repo with ~2.5 million loose objects revealed 12% of
the CPU time was spent in strbuf_addf().
Add a new performance test to p4211-line-log.sh that is more
sensitive to this cache-loading. By limiting to 1000 commits, we
more closely resemble user wait time when reading history into a
pager.

does not mention any special handling for the number 0, but the
implementation before commit 9f7e4bfa3b ("diff: remove silent clamp of

The commit 9f7e4bfa3b changed that behavior, treating 0 as 0. Revert
this behavior to what it was previously. This allows existing scripts

When a text file had been commited with CRLF and the file is commited
again, the CRLF are kept if .gitattributs has "text=auto".
This is done by analyzing the content of the blob stored in the index:
If a '\r' is found, Git assumes that the blob was commited with CRLF.
The simple search for a '\r' does not always work as expected:
A file is encoded in UTF-16 with CRLF and commited. Git treats it as binary.
Now the content is converted into UTF-8. At the next commit Git treats the
file as text, the CRLF should be converted into LF, but isn't.
Replace has_cr_in_index() with has_crlf_in_index(). When no '\r' is found,
0 is returned directly, this is the most common case.
If a '\r' is found, the content is analyzed more deeply.

Make it behave more like 'git checkout <branch>' when the branch doesn't
exist locally, but a remote tracking branch uniquely matches the desired
branch name, i.e. create a new branch from the remote tracking branch
and set the upstream to the remote tracking branch.

Fix a bug in the compilation of PCRE2 patterns under JIT (the most
common runtime configuration). Any pattern with a (*NO_JIT) verb would
segfault in any currently released PCRE2 version:
$ git grep -P '(*NO_JIT)hi.*there'
Segmentation fault
That this segfaulted was a bug in PCRE2 itself, after reporting it[1]
on pcre-dev it's been fixed in a yet-to-be-released version of
PCRE (presumably released first as 10.31). Now it'll die with:
$ git grep -P '(*NO_JIT)hi.*there'
fatal: pcre2_jit_match failed with error code -45: bad JIT option
But the cause of the bug is in our own code dating back to my
94da9193a6 ("grep: add support for PCRE v2", 2017-06-01).
As explained at more length in the comment being added here, it isn't
sufficient to just check pcre2_config() to see whether the JIT should
be used, pcre2_pattern_info() also has to be asked.
This is something I discovered myself when fiddling around with PCRE2
verbs in patterns passed to git. I don't expect that any user of git
has encountered this given the obscurity of passing PCRE2 verbs
through to the library, along with the relative obscurity of (*NO_JIT)
itself.

Add LIBPCRE1 and LIBPCRE2 prerequisites which are true when git is
compiled with USE_LIBPCRE1=YesPlease or USE_LIBPCRE2=YesPlease,
respectively.
The syntax of PCRE1 and PCRE2 isn't the same in all cases (see
pcresyntax(3) and pcre2syntax(3)). If test are added that test for
those they'll need to be guarded by these new prerequisites.
The subsequent patch will make use of LIBPCRE2, so LIBPCRE1 isn't
strictly needed for now, but let's add it for consistency and so that
checking for it doesn't have to be done with the less obvious "PCRE,
!LIBPCRE2", which while semantically the same is more confusing, and
would lead to bugs if PCRE v3 is ever released as the tests would mean
v1, not any non-v2 version.

When `log --decorate` is used, git will decorate commits with all
available refs. While in most cases this may give the desired effect,
under some conditions it can lead to excessively verbose output.
Introduce two command line options, `--decorate-refs=<pattern>` and
`--decorate-refs-exclude=<pattern>` to allow the user to select which
refs are used in decoration.
When "--decorate-refs=<pattern>" is given, only the refs that match the
pattern are used in decoration. The refs that match the pattern when
"--decorate-refs-exclude=<pattern>" is given, are never used in
decoration.
These options follow the same convention for mixing negative and
positive patterns across the system, assuming that the inclusive default
is to match all refs available.
(1) if there is no positive pattern given, pretend as if an
inclusive default positive pattern was given;
(2) for each candidate, reject it if it matches no positive
pattern, or if it matches any one of the negative patterns.
The rules for what is considered a match are slightly different from the
rules used elsewhere.
Commands like `log --glob` assume a trailing '/*' when glob chars are
not present in the pattern. This makes it difficult to specify a single
ref. On the other hand, commands like `describe --match --all` allow
specifying exact refs, but do not have the convenience of allowing
"shorthand refs" like 'refs/heads' or 'heads' to refer to
'refs/heads/*'.
The commands introduced in this patch consider a match if:
(a) the pattern contains globs chars,
and regular pattern matching returns a match.
(b) the pattern does not contain glob chars,
and ref '<pattern>' exists, or if ref exists under '<pattern>/'
This allows both behaviours (allowing single refs and shorthand refs)
yet remaining compatible with existent commands.

When trying to connect to an ssh:// URL with port explicitly specified

This requires updating the GIT_SSH setting in t5603-clone-dirname.sh.
That test is about the directory name produced when cloning various

not declare that it supports a port argument; update it to set
GIT_SSH_VARIANT=ssh to do so. (Real-life ssh wrappers that pass a

Android's "repo" tool is a tool for managing a large codebase
consisting of multiple smaller repositories, similar to Git's
submodule feature. Starting with Git 94b8ae5a (ssh: introduce a
'simple' ssh variant, 2017-10-16), users noticed that it stopped
handling the port in ssh:// URLs.
The cause: when it encounters ssh:// URLs, repo pre-connects to the
server and sets GIT_SSH to a helper ".repo/repo/git_ssh" that reuses
that connection. Before 94b8ae5a, the helper was assumed to support
OpenSSH options for lack of a better guess and got passed a -p option
to set the port. After that patch, it uses the new default of a
simple helper that does not accept an option to set the port.
The next release of "repo" will set GIT_SSH_VARIANT to "ssh" to avoid
that. But users of old versions and of other similar GIT_SSH
implementations would not get the benefit of that fix.
So update the default to use OpenSSH options again, with a twist. As
observed in 94b8ae5a, we cannot assume that $GIT_SSH always handles
OpenSSH options: common helpers such as travis-ci's dpl[*] are
configured using GIT_SSH and do not accept OpenSSH options. So make
the default a new variant "auto", with the following behavior:
1. First, check for a recognized basename, like today.
2. If the basename is not recognized, check whether $GIT_SSH supports
OpenSSH options by running
$GIT_SSH -G <options> <host>
This returns status 0 and prints configuration in OpenSSH if it
recognizes all <options> and returns status 255 if it encounters
an unrecognized option. A wrapper script like
exec ssh -- "$@"
would fail with
ssh: Could not resolve hostname -g: Name or service not known
, correctly reflecting that it does not support OpenSSH options.
The command is run with stdin, stdout, and stderr redirected to
/dev/null so even a command that expects a terminal would exit
immediately.
3. Based on the result from step (2), behave like "ssh" (if it
succeeded) or "simple" (if it failed).
This way, the default ssh variant for unrecognized commands can handle
both the repo and dpl cases as intended.
This autodetection has been running on Google workstations since
2017-10-23 with no reported negative effects.

Simplify by not allowing the copied ssh wrapper to persist between
tests. This way, tests can be safely reordered, added, and removed
with less fear of hidden side effects.
This also avoids having to call setup_ssh_wrapper to restore the value
of GIT_SSH after this battery of tests, since it means each test will
restore it individually.
Noticed because on Windows, if `uplink.exe` exists, the MSYS2 Bash
will overwrite that when redirecting via `>uplink`. A proposed test
wrote a script to 'uplink' after a previous test created uplink.exe
using copy_ssh_wrapper_as, so the script written with '>uplink' had
the wrong filename and failed.

Since fetch often deals with object-ids we don't have (yet),
it's an easy mistake for it to use a function like
parse_object() that gives the correct result (e.g., NULL)
but does so very slowly (because after failing to find the
object, we re-scan the pack directory looking for new
packs).
The regular test suite won't catch this because the end
result is correct, but we would want to know about
performance regressions, too. Let's add a test to the
regression suite.
Note that this uses a synthetic repository that has a large
number of packs. That's not ideal, as it means we're not
testing what "normal" users see (in fact, some of these
problems have existed for ages without anybody noticing
simply because a rescan on a normal repository just isn't
that expensive).
So what we're really looking for here is the spike you'd
notice in a pathological case (a lot of unknown objects
coming into a repo with a lot of packs). If that's fast,
then the normal cases should be, too.
Note that the test also makes liberal use of $MODERN_GIT for
setup; some of these regressions go back a ways, and we
should be able to use it to find the problems there.

Make it safer to normalize the line endings in a repository.
Files that had been commited with CRLF will be commited with LF.
The old way to normalize a repo was like this:
# Make sure that there are not untracked files
$ echo "* text=auto" >.gitattributes
$ git read-tree --empty
$ git add .
$ git commit -m "Introduce end-of-line normalization"
The user must make sure that there are no untracked files,
otherwise they would have been added and tracked from now on.
The new "add --renormalize" does not add untracked files:
$ echo "* text=auto" >.gitattributes
$ git add --renormalize .
$ git commit -m "Introduce end-of-line normalization"
Note that "git add --renormalize <pathspec>" is the short form for
"git add -u --renormalize <pathspec>".
While at it, document that the same renormalization may be needed,

The code for a newly added path assumed that the path was a normal file,
and thus checked for there being a directory still being in the way of
the file. Note that since unpack_trees() does path-in-the-way checks
already, the only way for there to be a directory in the way at this
point in the code, is if there is some kind of D/F conflict in the merge.
For a submodule addition on HEAD's side of history, the submodule would
have already been present. This means that we do expect there to be a
directory present but should not consider it to be "in the way"; instead,
it's the expected submodule. So, when there's a submodule addition from
