NAME
Git::SVN::Fetcher - tree delta consumer for "git svn fetch"
SYNOPSIS
use SVN::Core;
use SVN::Ra;
use Git::SVN;
use Git::SVN::Fetcher;
use Git;
my $gs = Git::SVN->find_by_url($url);
my $ra = SVN::Ra->new(url => $url);
my $editor = Git::SVN::Fetcher->new($gs);
my $reporter = $ra->do_update($SVN::Core::INVALID_REVNUM, '',
1, $editor);
$reporter->set_path('', $old_rev, 0);
$reporter->finish_report;
my $tree = $gs->tmp_index_do(sub { command_oneline('write-tree') });
foreach my $path (keys %{$editor->{dir_prop}) {
my $props = $editor->{dir_prop}{$path};
foreach my $prop (keys %$props) {
print "property $prop at $path changed to $props->{$prop}\n";
}
}
foreach my $path (keys %{$editor->{empty}) {
my $action = $editor->{empty}{$path} ? 'added' : 'removed';
print "empty directory $path $action\n";
}
foreach my $path (keys %{$editor->{file_prop}) { ... }
foreach my $parent (keys %{$editor->{absent_dir}}) {
my @children = @{$editor->{abstent_dir}{$parent}};

foreach @children;
}
foreach my $parent (keys %{$editor->{absent_file}) { ... }
DESCRIPTION
This is a subclass of "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 git svn fetch could use
to populate new commits and new entries for unhandled.log. More
specifically:
o Additions, removals, and modifications of files are propagated to
git-svn's index file $GIT_DIR/svn/$refname/index using git update-
index.
o Changes in Subversion path properties are recorded in the
"dir_prop" and "file_prop" fields (which are hashes).
o Addition and removal of empty directories are indicated by entries
with value 1 and 0 respectively in the "empty" hash.
o Paths that are present but cannot be conveyed (presumably due to
permissions) are recorded in the "absent_file" and "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.
The interface is unstable. Do not use this module unless you are
developing git-svn.
DEPENDENCIES
SVN::Delta from the Subversion perl bindings, the core Carp and
File::Basename modules, and git's Git helper module.
"Git::SVN::Fetcher" has not been tested using callers other than git-
