Ævar Arnfjörð Bjarmason f0e19cb7ce Git.pm: add the "use warnings" pragma
Amend Git.pm to load the "warnings" pragma like the rest of the code
in perl/ in addition to the existing "strict" pragma. This is
considered the bare minimum best practice in Perl.

Ever since this code was introduced in b1edc53d06 ("Introduce
Git.pm (v4)", 2006-06-24) it's only been using "strict", not
"warnings".

This leaves contrib/buildsystems/Generators/{QMake,VCproj}.pm and
contrib/mw-to-git/Git/Mediawiki.pm without "use warnings". Amending
those would be a sensible follow-up change, but I don't have an easy
way to test those so I'm not changing them.

Ævar Arnfjörð Bjarmason 872ba001f8 Git.pm: remove redundant "use strict" from sub-package
In Perl the "use strict/warnings" pragmas are lexical, thus there's no
reason to do:

    package Foo;
    use strict;
    package Bar;
    use strict;
    $x = 5;

To satisfy the desire that the undeclared $x variable will be spotted
at compile-time. It's enough to include the first "use strict".

This functionally changes nothing, but makes a subsequent change where
"use warnings" will be added to Git.pm less confusing and less
verbose, since as with "strict" we'll only need to do that at the top
of the file.

Changes code initially added in a6065b548f ("Git.pm: Try to support
ActiveState output pipe", 2006-06-25).

Ævar Arnfjörð Bjarmason 20d2a30f8f Makefile: replace perl/Makefile.PL with simple make rules
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.

Matthieu Moy e3fdbcc8e1 parse_mailboxes: accept extra text after <...> address
The test introduced in this commit succeeds without the patch to Git.pm
if Mail::Address is installed, but fails otherwise because our in-house
parser does not accept any text after the email address. They succeed
both with and without Mail::Address after this commit.

Mail::Address accepts extra text and considers it as part of the name,
iff the address is surrounded with <...>. The implementation mimics
this behavior as closely as possible.

This mostly restores the behavior we had before b1c8a11 (send-email:
allow multiple emails using --cc, --to and --bcc, 2015-06-30), but we
keep the possibility to handle comma-separated lists.

Johannes Schindelin 888ab716ad Git.pm: stop assuming that absolute paths start with a slash
On Windows, absolute paths never start with a slash, unless a POSIX
emulation layer is used. The latter is the case for MSYS2's Perl that
Git for Windows leverages. However, in the tests we also go through
plain `git.exe`, which does *not* leverage the POSIX emulation layer,
and therefore the paths we pass to Perl may actually be DOS-style paths
such as C:/Program Files/Git.

So let's just use Perl's own way to test whether a given path is
absolute or not instead of home-brewing our own.

This patch partially fixes t7800 and t9700 when running in Git for
Windows' SDK.

Remi Lespinet 8d314d7afe send-email: reduce dependencies impact on parse_address_line
parse_address_line had not the same behavior whether the user had
Mail::Address or not. Teach parse_address_line to behave like
Mail::Address.

When the user input is correct, this implementation behaves
exactly like Mail::Address except when there are quotes
inside the name:

  "Jane Do"e <jdoe@example.com>

In this case the result of parse_address_line is:

  With M::A : "Jane Do" e <jdoe@example.com>
  Without   : "Jane Do e" <jdoe@example.com>

When the user input is not correct, the behavior is also mostly
the same.

Unlike Mail::Address, this doesn't parse groups and recursive
commentaries.

as _temp_cache needs a slightly different test than is provided

The actual complaint appears to be a bug in the underlying
implementation.  What's interesting here is that it is apparently
_triggered_ by closing stderr, which results in (from strace)

  write(2, "fatal: Needed a single revision\n", 32) = -1 EBADF (Bad file descriptor)
  write(2, "\0", 1) = -1 EBADF (Bad file descriptor)

Closing stderr is a bad idea anyway: there is a very real chance that
we print fatal error messages to some other file that just happens to
be opened on the now-free FD 2.  So let's not do that.

As pointed out by Eric Wong (thanks), the initial close needs to go:
die() would again write nowhere if we close STDERR beforehand.

a file descriptor and do not use it ourselves.

Previous code would crash on all files > 2 Gib, when the offset
variable became negative (perhaps below the level of perl),
resulting in a crash.  On a 32 bit system, or a system with low
memory it might crash before reaching 2 GiB due to memory
exhaustion.

This code may leave a partial file behind in case of failure, where
the old code would leave a completely empty file.  Neither version
verifies the correctness of the content.  Calling code must take
care of verification and cleanup.

Michal Nazarewicz f4c0035de6 Git.pm: allow pipes to be closed prior to calling command_close_bidi_pipe
The command_close_bidi_pipe() function will insist on closing both
input and output pipes returned by command_bidi_pipe().  With this
change it is possible to close one of the pipes in advance and pass
undef as an argument.

Michal Nazarewicz 1323dba6af Git.pm: refactor command_close_bidi_pipe to use _cmd_close
The body of the loop in command_close_bidi_pipe sub is identical to
what _cmd_close sub does.

Instead of duplicating, refactor _cmd_close so that it accepts a
list of file handles to be closed, which makes it usable with
command_close_bidi_pipe.

Ben Walton 75f7b5dfc4 perl/Git.pm: fix get_tz_offset to properly handle DST boundary cases
When passed a local time that was on the boundary of a DST change,
get_tz_offset returned a GMT offset that was incorrect (off by one
hour).  This is because the time was converted to GMT and then back to
a time stamp via timelocal() which cannot disambiguate boundary cases
as noted in its documentation.

Modify this algorithm, using an approach suggested in

  http://article.gmane.org/gmane.comp.version-control.git/213871

to first convert the timestamp in question to two broken down forms
with localtime() and gmtime(), and then compute what timestamps
these two broken down forms would represent in GMT (i.e. a timezone
that does not have DST issues) by applying timegm() on them.  The
difference between the resulting timestamps is the timezone offset.

This avoids the ambigious conversion and allows a correct time to be
returned on every occassion.

Ben Walton 68868ff573 Move Git::SVN::get_tz to Git::get_tz_offset
This function has utility outside of the SVN module for any routine
that needs the equivalent of GNU strftime's %z formatting option.
Move it to the top-level Git.pm so that non-SVN modules don't need to
import the SVN module to use it.

The rename makes the purpose of the function clearer.

Sven Strickroth e9263e4580 git-svn, perl/Git.pm: extend and use Git->prompt method for querying users
git-svn reads usernames and other user queries from an interactive
terminal. This cause GUIs (w/o STDIN connected) to hang waiting forever
for git-svn to complete (http://code.google.com/p/tortoisegit/issues/detail?id=967).

This change extends the Git::prompt helper, so that it can also be used
for non password queries, and makes use of it instead of using
hand-rolled prompt-response code that only works with the interactive
terminal.

Masatake Osanai 48d9e6ae4b perl: command_bidi_pipe() method should set-up git environmens
When command_input_pipe and command_output_pipe are used as a
method of a Git::repository instance, they eventually call into
_cmd_exec method that sets up the execution environment such as
GIT_DIR, GIT_WORK_TREE environment variables and the current
working directory in the child process that interacts with the
repository.

command_bidi_pipe however didn't expect to be called as such, and
lacked all these set-up.  Because of this, a program that did this
did not work as expected:

    my $repo = Git->repository(Directory => '/some/where/else');
    my ($pid, $in, $out, $ctx) =
    $repo->command_bidi_pipe(qw(hash-object -w --stdin-paths));

This patch refactors the _cmd_exec into _setup_git_cmd_env that
sets up the execution environment, and makes _cmd_exec and
command_bidi_pipe to use it.

Note that unlike _cmd_exec that execv's a git command as an
external process, command_bidi_pipe is called from the main line
of control, and the execution environment needs to be restored
after open2() does its magic.

Ævar Arnfjörð Bjarmason d48b284183 perl: bump the required Perl version to 5.8 from 5.6.[21]
Formalize our dependency on perl 5.8, bumped from 5.6.[12]. We already
used the three-arg form of open() which was introduced in 5.6.1, but
t/t9700/test.pl explicitly depended on 5.6.2.

However git-add--interactive.pl has been failing on the 5.6 line since
it was introduced in v1.5.0-rc0~12^2~2 back in 2006 due to this open
syntax:

    sub run_cmd_pipe {
           my $fh = undef;
           open($fh, '-|', @_) or die;
           return <$fh>;
    }

Which when executed dies on "Can't use an undefined value as
filehandle reference". Several of our tests also fail on 5.6 (even
more when compiled with NO_PERL_MAKEMAKER=1):

    t2016-checkout-patch.sh
    t3904-stash-patch.sh
    t3701-add-interactive.sh
    t7105-reset-patch.sh
    t7501-commit.sh
    t9700-perl-git.sh

Our code is bitrotting on 5.6 with no-one interested in fixing it, and
pinning us to such an ancient release of Perl is keeping us from using
useful features introduced in the 5.8 release.

The 5.6 series is now over 10 years old, and the 5.6.2 maintenance
release almost 7. 5.8 on the other hand is more than 8 years old.

All the modern Unix-like operating systems have now upgraded to it or
a later version, and 5.8 packages are available for old IRIX, AIX
Solaris and Tru64 systems.
