=head1 NAME
|
||||
|
||||
Git::I18N - Perl interface to Git's Gettext localizations
|
||||
|
||||
=head1 SYNOPSIS
|
||||
|
||||
use Git::I18N;
|
||||
|
||||
print __("Welcome to Git!\n");
|
||||
|
||||
printf __("The following error occurred: %s\n"), $error;
|
||||
|
||||
printf __n("committed %d file\n", "committed %d files\n", $files), $files;
|
||||
|
||||
|
||||
=head1 DESCRIPTION
|
||||
|
||||
Git's internal Perl interface to gettext via L<Locale::Messages>. If
|
||||
L<Locale::Messages> can't be loaded (it's not a core module) we
|
||||
provide stub passthrough fallbacks.
|
||||
|
||||
This is a distilled interface to gettext, see C<info '(gettext)Perl'>
|
||||
for the full interface. This module implements only a small part of
|
||||
it.
|
||||
|
||||
=head1 FUNCTIONS
|
||||
|
||||
=head2 __($)
|
||||
|
||||
L<Locale::Messages>'s gettext function if all goes well, otherwise our
|
||||
passthrough fallback function.
|
||||
|
||||
=head2 __n($$$)
|
||||
|
||||
L<Locale::Messages>'s ngettext function or passthrough fallback function.
|
||||
|
||||
=head2 N__($)
|
||||
|
||||
No-operation that only returns its argument. Use this if you want xgettext to
|
||||
extract the text to the pot template but do not want to trigger retrival of the
|
||||
translation at run time.

=head1 NAME
|
||||
|
||||
Git::LoadCPAN - Wrapper for loading modules from the CPAN (OS) or Git's own copy
|
||||
|
||||
=head1 DESCRIPTION
|
||||
|
||||
The Perl code in Git depends on some modules from the CPAN, but we
|
||||
don't want to make those a hard requirement for anyone building from
|
||||
source.
|
||||
|
||||
Therefore the L<Git::LoadCPAN> namespace shipped with Git contains
|
||||
wrapper modules like C<Git::LoadCPAN::Module::Name> that will first
|
||||
attempt to load C<Module::Name> from the OS, and if that doesn't work
|
||||
will fall back on C<FromCPAN::Module::Name> shipped with Git itself.
|
||||
|
||||
Usually distributors will not ship with Git's Git::FromCPAN tree at
|
||||
all via the C<NO_PERL_CPAN_FALLBACKS> option, preferring to use their
|
||||
own packaging of CPAN modules instead.
|
||||
|
||||
This module is only intended to be used for code shipping in the
|
||||
C<git.git> repository. Use it for anything else at your peril!
|
||||
|
||||
=cut
|
||||
|
||||
# NO_PERL_CPAN_FALLBACKS_STR evades the sed search-replace from the
|
||||
# Makefile, and allows for detecting whether the module is loaded from
|
||||
# perl/Git as opposed to perl/build/Git, which is useful for one-off
|
||||
# testing without having Error.pm et al installed.
|
||||
use constant NO_PERL_CPAN_FALLBACKS_STR => '@@' . 'NO_PERL_CPAN_FALLBACKS' . '@@';

BUG: The '%s' module is not here, but NO_PERL_CPAN_FALLBACKS was set!
|
||||
|
||||
Git needs this Perl module from the CPAN, and will by default ship
|
||||
with a copy of it. This Git was built with NO_PERL_CPAN_FALLBACKS,
|
||||
meaning that whoever built it promised to provide this module.
|
||||
|
||||
You're seeing this error because they broke that promise, and we can't
|
||||
load our fallback version, since we were asked not to install it.
|
||||
|
||||
If you're seeing this error and didn't package Git yourself the
|
||||
package you're using is broken, or your system is broken. This error
|
||||
won't appear if Git is built without NO_PERL_CPAN_FALLBACKS (instead
|
||||
we'll use our fallback version of the module).

=head1 DESCRIPTION
|
||||
|
||||
This module is an implementation detail of the "git svn" command.
|
||||
Do not use it unless you are developing git-svn.
|
||||
|
||||
This module adapts the C<SVN::Delta::Editor> object returned by
|
||||
C<SVN::Delta::get_commit_editor> and drives it to convey the
|
||||
difference between two git tree objects to a remote Subversion
|
||||
repository.
|
||||
|
||||
The interface will change as git-svn evolves.
|
||||
|
||||
=head1 DEPENDENCIES
|
||||
|
||||
Subversion perl bindings,
|
||||
the core L<Carp> module,
|
||||
and git's L<Git> helper module.
|
||||
|
||||
C<Git::SVN::Editor> has not been tested using callers other than
|
||||
B<git-svn> itself.
|
||||
|
||||
=head1 SEE ALSO
|
||||
|
||||
L<SVN::Delta>,
|
||||
L<Git::SVN::Fetcher>.
|
||||
|
||||
=head1 INCOMPATIBILITIES
|
||||
|
||||
None reported.
|
||||
|
||||
=head1 BUGS
|
||||
|
||||

=head1 DESCRIPTION
|
||||
|
||||
This is a subclass of C<SVN::Delta::Editor>, which means it implements
|
||||
callbacks to act as a consumer of Subversion tree deltas. This
|
||||
particular implementation of those callbacks is meant to store
|
||||
information about the resulting content which B<git svn fetch> could
|
||||
use to populate new commits and new entries for F<unhandled.log>.
|
||||
More specifically:
|
||||
|
||||
=over
|
||||
|
||||
=item * Additions, removals, and modifications of files are propagated
|
||||
to git-svn's index file F<$GIT_DIR/svn/$refname/index> using
|
||||
B<git update-index>.
|
||||
|
||||
=item * Changes in Subversion path properties are recorded in the
|
||||
C<dir_prop> and C<file_prop> fields (which are hashes).
|
||||
|
||||
=item * Addition and removal of empty directories are indicated by
|
||||
entries with value 1 and 0 respectively in the C<empty> hash.
|
||||
|
||||
=item * Paths that are present but cannot be conveyed (presumably due
|
||||
to permissions) are recorded in the C<absent_file> and
|
||||
C<absent_dirs> hashes. For each key, the corresponding value is
|
||||
a list of paths under that directory that were present but
|
||||
could not be conveyed.
|
||||
|
||||
=back
|
||||
|
||||
The interface is unstable. Do not use this module unless you are
|
||||
developing git-svn.
|
||||
|
||||
=head1 DEPENDENCIES
|
||||
|
||||
L<SVN::Delta> from the Subversion perl bindings,
|
||||
the core L<Carp> and L<File::Basename> modules,
|
||||
and git's L<Git> helper module.
|
||||
|
||||
C<Git::SVN::Fetcher> has not been tested using callers other than
|
||||
B<git-svn> itself.

=head1 NAME
|
||||
|
||||
Git::SVN::Memoize::YAML - store Memoized data in YAML format
|
||||
|
||||
=head1 SYNOPSIS
|
||||
|
||||
use Memoize;
|
||||
use Git::SVN::Memoize::YAML;
|
||||
|
||||
tie my %cache => 'Git::SVN::Memoize::YAML', $filename;
|
||||
memoize('slow_function', SCALAR_CACHE => [HASH => \%cache]);
|
||||
slow_function(arguments);
|
||||
|
||||
=head1 DESCRIPTION
|
||||
|
||||
This module provides a class that can be used to tie a hash to a
|
||||
YAML file. The file is read when the hash is initialized and
|
||||
rewritten when the hash is destroyed.
|
||||
|
||||
The intent is to allow L<Memoize> to back its cache with a file in
|
||||
YAML format, just like L<Memoize::Storable> allows L<Memoize> to
|
||||
back its cache with a file in Storable format. Unlike the Storable
|
||||
format, the YAML format is platform-independent and fairly stable.
|
||||
|
||||
Carps on error.
|
||||
|
||||
=head1 DIAGNOSTICS
|
||||
|
||||
See L<YAML::Any>.
|
||||
|
||||
=head1 DEPENDENCIES
|
||||
|
||||
L<YAML::Any> from CPAN.
|
||||
|
||||
=head1 INCOMPATIBILITIES
|
||||
|
||||
None reported.
|
||||
|
||||
=head1 BUGS
|
||||
|
||||
The entire cache is read into a Perl hash when loading the file,
|
||||
so this is not very scalable.

=head1 DESCRIPTION
|
||||
|
||||
This module is an implementation detail of the "git svn" command.
|
||||
It implements git-svn's authentication policy. Do not use it unless
|
||||
you are developing git-svn.
|
||||
|
||||
The interface will change as git-svn evolves.

Git::SVN::Ra - Subversion remote access functions for git-svn
|
||||
|
||||
=head1 SYNOPSIS
|
||||
|
||||
use Git::SVN::Ra;
|
||||
|
||||
my $ra = Git::SVN::Ra->new($branchurl);
|
||||
my ($dirents, $fetched_revnum, $props) =
|
||||
$ra->get_dir('.', $SVN::Core::INVALID_REVNUM);
|
||||
|
||||
=head1 DESCRIPTION
|
||||
|
||||
This is a wrapper around the L<SVN::Ra> module for use by B<git-svn>.
|
||||
It fills in some default parameters (such as the authentication
|
||||
scheme), smooths over incompatibilities between libsvn versions, adds
|
||||
caching, and implements some functions specific to B<git-svn>.
|
||||
|
||||
Do not use it unless you are developing git-svn. The interface will
|
||||
change as git-svn evolves.
|
||||
|
||||
=head1 DEPENDENCIES
|
||||
|
||||
Subversion perl bindings,
|
||||
L<Git::SVN>.
|
||||
|
||||
C<Git::SVN::Ra> has not been tested using callers other than
|
||||
B<git-svn> itself.
|
||||
|
||||
=head1 SEE ALSO
|
||||
|
||||

|
||||
|
||||
=head1 INCOMPATIBILITIES
|
||||
|
||||
None reported.
|
||||
|
||||
=head1 BUGS
|

|

None.

Git::SVN::Utils - utility functions used across Git::SVN

=head1 DESCRIPTION
|

|

This module contains functions which are useful across many different

parts of Git::SVN. Mostly it's a place to put utility functions

rather than duplicate the code or have classes grabbing at other
|
||||
classes.

|
||||
|

All functions can be imported only on request.
