SVN::Dump(3pm) User Contributed Perl Documentation SVN::Dump(3pm) NAME
SVN::Dump - A Perl interface to Subversion dumps SYNOPSIS
#!/usr/bin/perl use strict; use warnings; use SVN::Dump; my $file = shift; my $dump = SVN::Dump->new( { file => $file } ); # compute some stats my %type; my %kind; while ( my $record = $dump->next_record() ) { $type{ $record->type() }++; $kind{ $record->get_header('Node-action') }++ if $record->type() eq 'node'; } # print the results print "Statistics for dump $file: ", " version: ", $dump->version(), " ", " uuid: ", $dump->uuid(), " ", " revisions: ", $type{revision}, " ", " nodes: ", $type{node}, " "; print map { sprintf " - %-7s: %d ", $_, $kind{$_} } sort keys %kind; DESCRIPTION
This module is an alpha release. The interfaces will probably change in the future, as I slowly learn my way inside the SVN dump format. An "SVN::Dump" object represents a Subversion dump. This module follow the semantics used in the reference document (the file notes/fs_dumprestore.txt in the Subversion source tree): o A dump is a collection of records ("SVN::Dump::Record" objects). o A record is composed of a set of headers (a "SVN::Dump::Headers" object), a set of properties (a "SVN::Dump::Property" object) and an optional bloc of text (a "SVN::Dump::Text" object). o Some special records ("delete" records with a "Node-kind" header) recursively contain included records. Each class has a "as_string()" method that prints its content in the dump format. The most basic thing you can do with "SVN::Dump" is simply copy a dump: use SVN::Dump; my $dump = SVN::Dump->new( 'mydump.svn' ); print $dump->as_string(); # only print the dump header while( $rec = $dump->next_record() ) { print $rec->as_string(); } After the operation, the resulting dump should be identical to the original dump. METHODS
"SVN::Dump" provides the following methods: new( \%args ) Return a new "SVN::Dump" object. The argument list is a hash reference. If the "SVN::Dump" object will read information from a file, the arguments "file" is used (as usal, "-" means "STDIN"); if the dump is read from a filehandle, "fh" is used. Extra options will be passed to the "SVN::Dump::Reader" object that is created. If the "SVN::Dump" isn't used to read information, the parameters "version" and "uuid" can be used to initialise the values of the "SVN-fs-dump-format-version" and "UUID" headers. next_record() Return the next record read from the dump. This is a "SVN::Dump::Record" object. version() format() Return the dump format version, if the version record has already been read, or if it was given in the constructor. uuid() Return the dump UUID, if there is an UUID record and it has been read, or if it was given in the constructor. as_string() Return a string representation of the dump specific blocks (the "format" and "uuid" blocks only).
