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_headers()->{'Node-action'} }++
if $record->type() eq 'node';
}
# print the results
print "Statistics for dump $file:\n",
" version: ", $dump->version(), "\n",
" uuid: ", $dump->uuid(), "\n",
" revisions: ", $type{revision}, "\n",
" nodes: ", $type{node}, "\n";
print map { sprintf " - %-7s: %d\n", $_, $kind{$_} } 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.
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).
