Description: | I needed a Subversion pre-commit hook script to commit based on the name and contents of the file being committed. I found a python example, so I thought I'd try something similar in perl. Warning: this seems to work, but I do not know if I've got the subclassing of the SVN::Delta::Editor methods correct (can't find good docs or examples). Advice is appreciated. |
#!/usr/bin/perl require SVN::Core; require SVN::Repos; require SVN::Fs; require SVN::Delta; package ChangeReceiver; my $file_re = qr/\.txt/; my $bad_re = qr/foo/; our @ISA = qw(SVN::Delta::Editor); sub add_file { return [0, $_[1]]; } sub open_file { return [0, $_[1]]; } sub apply_textdelta { $_[1]->[0] = 1; return; } sub close_file { my ($self, $file_baton) = @_; my ($changed, $path) = @$file_baton; return unless $changed; return unless $path =~ /$file_re/; my $pool = SVN::Pool->new_default_sub; my $stream = SVN::Fs::file_contents( $self->{txn_root}, $path, $pool + ); my $bytes; my $byte_cnt = 0; my $exit_code = 0; my $buffer = ''; while ( $bytes = $stream->read( $buffer, $SVN::Core::STREAM_CHUNK_SI +ZE, 0 ) ) { if ( $buffer =~ /$bad_re/ ) { $exit_code=1; last; } $byte_cnt += $bytes; $buffer = ''; } $stream->close; if ($exit_code) { warn "Bad file: $path\n"; exit $exit_code; } return; } package main; my ($rep, $txn) = @ARGV; my $rep = SVN::Repos::open($rep); my $fs = $rep->fs; my $txn_ptr = $fs->open_txn($txn); my $txn_root = SVN::Fs::txn_root($txn_ptr); my $base_root = $fs->revision_root($fs_ptr, SVN::Fs::txn_base_revision +($txn_ptr)); my $editor = ChangeReceiver->new; $editor->{txn_root} = $txn_root; # Bad OO I know SVN::Repos::dir_delta($base_root, '', '', $txn_root, '', $editor, sub{ +1}, 1, 1, 0, 0); exit 0; |
