In Git 2.39, Git.pm stopped working in a bare repository, which has
been corrected.
* jk/git-pm-bare-repo-fix:
Git.pm: use "rev-parse --absolute-git-dir" rather than perl code
Git.pm: fix bare repository search with Directory option
When we open a repository with the "Directory" option, we use "rev-parse
--git-dir" to get the path relative to that directory, and then use
Cwd::abs_path() to make it absolute (since our process working directory
may not be the same).
These days we can just ask for "--absolute-git-dir" instead, which saves
us a little code. That option was added in Git v2.13.0 via a2f5a87626
(rev-parse: add '--absolute-git-dir' option, 2017-02-03). I don't think
we make any promises about running mismatched versions of git and
Git.pm, but even if somebody tries it, that's sufficiently old that it
should be OK.

When opening a bare repository like:
Git->repository(Directory => '/path/to/bare.git');
we will incorrectly point the repository object at the _current_
directory, not the one specified by the option.
The bug was introduced by 20da61f25f (Git.pm: trust rev-parse to find
bare repositories, 2022-10-22). Before then, we'd ask "rev-parse
--git-dir" if it was a Git repo, and if it returned anything, we'd
correctly convert that result to an absolute path using File::Spec and
Cwd::abs_path(). If it didn't, we'd guess it might be a bare repository
and find it ourselves, which was wrong (rev-parse should find even a
bare repo, and our search circumvented some of its rules).
That commit dropped most of the custom bare-repo search code in favor of
using "rev-parse --is-bare-repository" and trusting the "--git-dir" it
returned. But it mistakenly left some of the bare-repo code path in
place, which was now broken. That code calls Cwd::abs_path($dir); prior
to 20da61f25f $dir contained the "Directory" option the user passed in.
But afterwards, it contains the output of "rev-parse --git-dir". And
since our tentative rev-parse command is invoked after changing
directory, it will always be the relative path "."! So we'll end up with
the absolute path of the process's current directory, not the Directory
option the caller asked for.
So the non-bare case is correct, but the bare one is broken. Our tests
only check the non-bare one, so we didn't notice. We can fix this by
running the same absolute-path fixup code for both sides.

When initializing a repository object, we run "git rev-parse --git-dir"
to let the C version of Git find the correct directory. But curiously,
if this fails we don't automatically say "not a git repository".
Instead, we do our own pure-perl check to see if we're in a bare
repository.
This makes little sense, as rev-parse will report both bare and non-bare
directories. This logic comes from d5c7721d58 (Git.pm: Add support for
subdirectories inside of working copies, 2006-06-24), but I don't see
any reason given why we can't just rely on rev-parse. Worse, because we
treat any non-error response from rev-parse as a non-bare repository,
we'll erroneously set the object's WorkingCopy, even in a bare
repository.
But it gets worse. Since 8959555cee (setup_git_directory(): add an owner
check for the top-level directory, 2022-03-02), it's actively wrong (and
dangerous). The perl code doesn't implement the same ownership checks.
And worse, after "finding" the bare repository, it sets GIT_DIR in the
environment, which tells any subsequent Git commands that we've
confirmed the directory is OK, and to trust us. I.e., it re-opens the
vulnerability plugged by 8959555cee when using Git.pm's repository
discovery code.
We can fix this by just relying on rev-parse to tell us when we're not
in a repository, which fixes the vulnerability. Furthermore, we'll ask
its --is-bare-repository function to tell us if we're bare or not, and
rely on that.

When attempting to initialize a repository object in an unsafe
directory, a syntax error is reported (Can't use string as a HASH ref
while strict refs in use). Fix this runtime error by adding the required
semicolon after the catch statement.
Without the semicolon, the result of the following line (i.e., the
result of Cwd::abs_path) is passed as the third argument to Error.pm's
catch function. That function expects that its third argument,
$clauses, is a hash reference, and trying to access a string as a hash
reference is a fatal error.

Fix misbehavior in Git.pm that dates back to the very first version of
the library in git.git added in b1edc53d06 (Introduce Git.pm (v4),
2006-06-24). When we fail to execute a command we shouldn't ignore all
signals, those can happen e.g. if abort() is called, or if the command
segfaults.
Because of this we'd consider e.g. a command that died due to LSAN
exiting with abort() successful, as is the case with the tests listed
as running successfully with SANITIZE=leak in 9081a421a6 (checkout:
fix "branch info" memory leaks, 2021-11-16). We did run them
successfully, but only because we ignored these errors.
This was then made worse by the use of "abort_on_error=1" for LSAN
added in 85b81b35ff (test-lib: set LSAN_OPTIONS to abort by default,
2017-09-05). Doing that makes sense, but without providing that option
we'd have a "$? >> 8" of "23" on failure, with abort_on_error=1 we'll
get "0".
All of our tests pass even without the SIGPIPE exception being added
here, but as the code appears to have been trying to ignore it let's
keep ignoring it for now.

Move the newly added "hooks_path" API in Git.pm to its only user in
git-send-email.perl. This was added in c8243933c7 (git-send-email:
Respect core.hooksPath setting, 2021-03-23), meaning that it hasn't
yet made it into a non-rc release of git.
The consensus with Git.pm is that we need to be considerate of
out-of-tree users who treat it as a public documented interface. We
should therefore be less willing to add new functionality to it, least
we be stuck supporting it after our own uses for it disappear.
In this case the git-send-email.perl hook invocation will probably be
replaced by a future "git hook run" command, and in the commit
preceding this one the "hooks_path" become nothing but a trivial
wrapper for "rev-parse --git-path hooks" anyway (with no
Cwd::abs_path() call), so let's just inline this command in

In c8243933c7 (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 c8243933c7 itself, but was revealed by my
ea7811b37e (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 53753a37d0 (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 53753a37d0 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.

We set "use warnings" in most of our perl code to catch problems. But as
the name implies, warnings just emit a message to stderr and don't
otherwise affect the program. So our tests are quite likely to miss that
warnings are being spewed, as most of them do not look at stderr.
We could ask perl to make all warnings fatal, but this is likely
annoying for non-developers, who would rather have a running program
with a warning than something that refuses to work at all.
So instead, let's teach the perl code to respect an environment variable
(GIT_PERL_FATAL_WARNINGS) to increase the severity of the warnings. This
can be set for day-to-day running if people want to be really pedantic,
but the primary use is to trigger it within the test suite.
We could also trigger that for every test run, but likewise even the
tests failing may be annoying to distro builders, etc (just as -Werror
would be for compiling C code). So we'll tie it to a special test-mode
variable (GIT_TEST_PERL_FATAL_WARNINGS) that can be set in the
environment or as a Makefile knob, and we'll automatically turn the knob
when DEVELOPER=1 is set. That should give developers and CI the more
careful view without disrupting normal users or packagers.
Note that the mapping from the GIT_TEST_* form to the GIT_* form in
test-lib.sh is necessary even if they had the same name: the perl
scripts need it to be normalized to a perl truth value, and we also have
to make sure it's exported (we might have gotten it from the
environment, but we might also have gotten it from GIT-BUILD-OPTIONS
directly).

The commit 9ab33150a0 ("perl: create and switch variables for hash

$sha1_short into $oid_short in the Subversion code, since git-svn now
understands SHA-256. However, one conversion was missed.
As a result, Perl complains about the use of this variable:
Use of uninitialized value $sha1_short in regexp compilation at
/usr/lib64/perl5/vendor_perl/5.30.3/Git/SVN/Log.pm line 301, <$fh>
line 6.
Because we're parsing raw diff output here, the likelihood is very low
that we'll actually misparse the data, since the only lines we're going
to get starting with colons are the ones we're expecting. Even if we
had a newline in a path, we'd end up with a quoted path. Our regex is
just less strict than we'd like it to be.
However, it's obviously undesirable that our code is emitting Perl
warnings, so let's convert it to use the proper variable name.

A build-time option has been added to allow Git to be told to refer

Broaden the RUNTIME_PREFIX flag to configure Git's Perl scripts to
locate the Git installation's Perl support libraries by resolving
against the script's path, rather than hard-coding that path at
build-time. Hard-coding at build time worked on previous
RUNTIME_PREFIX configurations (i.e., Windows) because the Perl
scripts were run within a virtual filesystem whose paths were
consistent regardless of the location of the actual installation.
This will no longer be the case for non-Windows RUNTIME_PREFIX users.
When enabled, RUNTIME_PREFIX now requires Perl's system paths to be
expressed relative to a common installation directory in the Makefile,
and uses that relationship to locate support files based on the known
starting point of the script being executed, much like RUNTIME_PREFIX
does for the Git binary.
This change enables Git's Perl scripts to work when their Git installation
is relocated or moved to another system, even when they are not in a
virtual filesystem environment.

Git.pm: add the "use warnings" pragma

perl: *.pm files should not have the executable bit
Before my 20d2a30f8f ("Makefile: replace perl/Makefile.PL with simple
make rules", 2017-12-10) on an OS package that removed the
private-Error.pm copy we carried around manually removing the OS's
Error.pm would yield:
$ git add -p
Can't locate Error.pm in @INC (you may need to install the Error module) [...]
Now, before this change we'll instead emit this more cryptic error:
$ git add -p
BUG: '/usr/share/perl5/Git/FromCPAN' should be a directory! at /usr/share/perl5/Git/Error.pm line 36.
This is a confusing error. Now if the new NO_PERL_CPAN_FALLBACKS
option is specified and we can't find the module we'll instead emit:
$ /tmp/git/bin/git add -p
BUG: The 'Error' module is not here, but NO_PERL_CPAN_FALLBACKS was set!
[...]
Where [...] is the lengthy explanation seen in the change below, which
explains what the potential breakage is, and how to fix it.
The reason for checking @@NO_PERL_CPAN_FALLBACKS@@] against the empty
string in Perl is as opposed to checking for a boolean value is that
that's (as far as I can tell) make's idea of a string that's set, and
e.g. NO_PERL_CPAN_FALLBACKS=0 is enough to set NO_PERL_CPAN_FALLBACKS.

Move the CPAN modules that have lived under perl/Git/FromCPAN since my
20d2a30f8f ("Makefile: replace perl/Makefile.PL with simple make
rules", 2017-12-10) to perl/FromCPAN.
A subsequent change will teach the Makefile to only install these
copies of CPAN modules if a flag that distro packagers would like to
set isn't set. Due to how the wildcard globbing is being done it's
much easier to accomplish that if they're moved to their own
directory.

Change the two wrappers that load from CPAN (local OS) or our own copy
to do so via the same codepath.
I added the Error.pm wrapper in 20d2a30f8f ("Makefile: replace
perl/Makefile.PL with simple make rules", 2017-12-10), and shortly
afterwards Matthieu Moy added a wrapper for Mail::Address in
bd869f67b9 ("send-email: add and use a local copy of Mail::Address",
2018-01-05).
His loader was simpler since Mail::Address doesn't have an "import"
method, but didn't do the same sanity checking; For example, a missing
FromCPAN directory (which OS packages are likely not to have) wouldn't
be explicitly warned about as a "BUG: ...".
Update both to use a common implementation based on the previous
Error.pm loader. Which has been amended to take the module to load as
parameter, as well as whether or not that module has an import
method.
This loader should be generic enough to handle almost all CPAN modules
out there, some use some crazy loading magic and wouldn't like being
wrapped like this, but that would be immediately obvious, and we'd
find out right away since the module wouldn't work at all.

Move the Git::Error and Git::Mail::Address wrappers to the
Git::LoadCPAN::Loader::* namespace, e.g. Git::LoadCPAN::Error. That
module will then either load Error from CPAN (if installed on the OS),
or use Git::FromCPAN::Error.
When I added the Error wrapper in 20d2a30f8f ("Makefile: replace
perl/Makefile.PL with simple make rules", 2017-12-10) I didn't think
about how confusing it would be to have these modules sitting in the
same tree as our normal modules. Let's put these all into
Git::{Load,From}CPAN::* to clearly distinguish them from the rest.
This also makes things a bit less confusing since there was already a
Git::Error namespace ever since 8b9150e3e3 ("Git.pm: Handle failed
commands' output", 2006-06-24).

Update our copy of Mail::Address from 2.19 (Aug 22, 2017) to 2.20 (Jan
23, 2018). Like the preceding Error.pm update this is done simply to
keep up-to-date with upstream, and as can be shown from the diff
there's no functional changes.

The Error.pm shipped with Git as a fallback if there was no Error.pm
on the system was released in April 2006. There's been dozens of
releases since then, the latest at August 7, 2017. Let's update to
that.
I don't know of anything we need from this new release or which this
fixes. This change is simply a matter of keeping up with
upstream. Before this users who'd install git via their package system
would get an up-to-date Error.pm, but if it's installed from source
they'd get one more than a decade old.
This undoes a local hack we'd accumulated in 96bc4de85c ("Eliminate
Scalar::Util usage from private-Error.pm", 2006-07-26), it's been
redundant since my d48b284183 ("perl: bump the required Perl version
to 5.8 from 5.6.[21]", 2010-09-24).
This also undoes 3a51467b94 ("Typo fix: replacing it's -> its",
2013-04-13). This is the Nth time I find that some upstream code of
ours (in contrib/, in sha1dc/ and now in perl/ ...) has diverged from
upstream because of some tree-wide typo fixing. Let's not do those
fixes against upstream projects, it's more valuable that we have a 1=1
mapping to upstream than to fix typos in docs we never even generate
from this code. If someone wants to fix typos in them fine, but they
should do it with a patch to upstream which git.git can then
incorporate.
The upstream code doesn't cleanly pass a --check, so I'm adding a
.gitattributes file for similar reasons as done for sha1dc in
5d184f468e ("sha1dc: ignore indent-with-non-tab whitespace
violations", 2017-06-06).

Since my d48b284183 ("perl: bump the required Perl version to 5.8 from
5.6.[21]", 2010-09-24), we've depended on 5.8, so there's no reason to
conditionally require File::Temp and File::Spec anymore. They were
first released with perl versions v5.6.1 and 5.00405, respectively.
This code was originally added in c14c8ceb13 ("Git.pm: Make File::Spec
and File::Temp requirement lazy", 2008-08-15), presumably to make
Git.pm work on 5.6.0.
