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} "; } } foreach my $path (keys %{$editor->{empty}) { my $action = $editor->{empty}{$path} ? 'added' : 'removed'; print "empty directory $path $action "; } foreach my $path (keys %{$editor->{file_prop}) { ... } foreach my $parent (keys %{$editor->{absent_dir}}) { my @children = @{$editor->{abstent_dir}{$parent}}; print "cannot fetch directory $parent/$_: not authorized? " 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, File::Basename, and IO::File modules, and git's Git helper module. "Git::SVN::Fetcher" has not been tested using callers other than git-svn itself. SEE ALSO
SVN::Delta, Git::SVN::Editor. INCOMPATIBILITIES
None reported. BUGS
None. perl v5.16.3 2013-06-10 Git::SVN::Fetcher(3)

NAME
SVN::Delta - Subversion delta functions SYNOPSIS
require SVN::Core; require SVN::Repos; require SVN::Delta; # driving an editor my $editor = SVN::Delta::Editor-> new(SVN::Repos::get_commit_editor($repos, "file://$repospath", '/', 'root', 'FOO', &committed)); my $rootbaton = $editor->open_root(0); my $fbaton = $editor->add_file('filea', $rootbaton, undef, -1); my $ret = $editor->apply_textdelta($fbaton, undef); SVN::TxDelta::send_string("FILEA CONTENT", @$ret); # implement an editor in perl SVN::Repos::dir_delta($root1, $path, undef, $root2, $path, SVN::Delta::Editor->new(_debug=>1), 1, 1, 0, 1 DESCRIPTION
SVN::Delta wraps delta related function in subversion. The most important one is SVN::Delta::Editor, the interface for describing tree deltas. by default SVN::Delta::Editor relays method calls to its internal member "_editor", which could either be an editor in C (such as the one you get from get_commit_editor), or another SVN::Delta::Editor object. SVN
::Delta::Editor Driving Editors If you want to drive a native editor (such as commit_editor obtained by SVN::Repos::get_commit_editor), create a SVN::Delta::Editor object with the native editor/baton pair. The object will then be ready to use and its method calls will be relayed to the native editor. Implementing Editors If you want to implement an editor, subclass SVN::Delta::Editor and implement the editors callbacks. see the METHODS section below. CONSTRUCTOR - new(...) new($editor, $editor_baton) Link to the native editor You can also pass a hash array to new: _debug Turn on debug. _editor An arrayref of the editor/baton pair or another SVN::Delta::Editor object to link with. METHODS Please consult the svn_delta.h section in the Subversion API. Member functions of svn_delta_editor_t could be called as methods of SVN::Delta::Editor objects, with the edit_baton omitted. The pool is also optional. If you are subclassing, the methods take exactly the same arguments as the member functions (note that void ** are returned data though as throughout the perl bindings), with the edit_baton omitted. BUGS
Functions returning editor/baton pair should really be typemapped to a SVN::Delta::Editor object. AUTHORS
