This is my first cut at a feature like that requested in [[todo/Moving_Pages]]. In case it gets mangled you can find it on [my site](http://www.betacantrips.com//attic/move.patch). A bunch of obvious shortcomings exist: * I'm not sure all the untaints are safe. * No precautions whatsoever are made to protect against race conditions or failures in the rcs\_move function. * movepage.tmpl doesn't exist yet. * Some code is duplicated between cgi\_movepage and cgi\_editpage, as well as rcs\_commit and rcs\_move. * The user interface is pretty lame -- there's no handy select list full of possible places to move it or anything. * I don't think I implemented cancelling. * from is redundant with page. * I don't think I called the right hook functions. * No redirect pages like those mentioned on [[todo/Moving_Pages]] exist yet, so none are created. * It's not possible to get there through the actions listed on the wiki page. Instead you can select "Edit" and then change "edit" to "move" in the location bar. Anyhow, here's the patch, for whatever good it does. diff -urx .svn ikiwiki/IkiWiki/CGI.pm ikiwiki-new/IkiWiki/CGI.pm --- ikiwiki/IkiWiki/CGI.pm 2007-01-04 03:52:47.000000000 -0800 +++ ikiwiki-new/IkiWiki/CGI.pm 2007-01-11 18:49:37.000000000 -0800 @@ -523,6 +523,97 @@ } } #}}} +sub cgi_movepage($$) { + my $q = shift; + my $session = shift; + eval q{use CGI::FormBuilder}; + error($@) if $@; + my @fields=qw(do from rcsinfo subpage page newname message); # subpage ignored so far + my @buttons=("Rename Page", "Cancel"); + + my $form = CGI::FormBuilder->new( + fields => \@fields, + header => 1, + charset => "utf-8", + method => 'POST', + action => $config{cgiurl}, + template => (-e "$config{templatedir}/movepage.tmpl" ? + {template_params("movepage.tpml")} : ""), + ); + run_hooks(formbuilder_setup => sub { + shift->(form => $form, cgi => $q, session => $session); + }); + + decode_form_utf8($form); + + # This untaint is safe because if the page doesn't exist, bail. + my $page = $form->field('page'); + $page = possibly_foolish_untaint($page); + if (! exists $pagesources{$page}) { + error("page does not exist"); + } + my $file=$pagesources{$page}; + my $type=pagetype($file); + + my $from; + if (defined $form->field('from')) { + ($from)=$form->field('from')=~/$config{wiki_file_regexp}/; + } + + $form->field(name => "do", type => 'hidden'); + $form->field(name => "from", type => 'hidden'); + $form->field(name => "rcsinfo", type => 'hidden'); + $form->field(name => "subpage", type => 'hidden'); + $form->field(name => "page", value => $page, force => 1); + $form->field(name => "newname", type => "text", size => 80); + $form->field(name => "message", type => "text", size => 80); + + if (! $form->submitted) { + $form->field(name => "rcsinfo", value => rcs_prepedit($file), + force => 1); + } + + if ($form->submitted eq "Cancel") { + redirect($q, "$config{url}/".htmlpage($from)); + return; + } + + if (! $form->submitted || $form->submitted eq "Preview" || + ! $form->validate) { + if ($form->field("do") eq "move"){ + page_locked($page, $session); + $form->tmpl_param("page_select", 0); + $form->field(name => "page", type => 'hidden'); + $form->field(name => "type", type => 'hidden'); + $form->title(sprintf(gettext("moving %s"), pagetitle($page))); + if (! defined $form->field('newname') || + ! length $form->field('newname')) { + $form->field(name => "newname", + value => pagetitle($page), force => 1); + } + + } + print $form->render(submit => \@buttons); + } + else{ + # This untaint is safe because titlepage removes any problematic + # characters. + my ($newname)=$form->field('newname'); + $newname=titlepage(possibly_foolish_untaint($newname)); + if (! defined $newname || ! length $newname || file_pruned($newname, $config{srcdir}) || $newname=~/^\//) { + error("bad page name"); + } + page_locked($page, $session); + + my $newfile = $newname .
