git-svn: make Git::SVN::RA a separate file
This slices off another 600 or so lines from the frighteningly long
git-svn.perl script.
The Git::SVN::Ra interface is similar enough to SVN::Ra that it is
probably safe to ignore most of its implementation on first reading.
(Documenting or moving functions that do not fit that pattern is left
as an exercise to the interested reader.)
[ew: rebased and fixed conflict against
commit c26ddce86d
(git-svn: platform auth providers are working only on 1.6.15 or newer)]

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
|
