This file includes usernames, and `ikiwiki-mass-rebuild` (which must run as root) changes to the specified user to rebuild their wiki. However, this means that adding new ikiwikis to the list must require administrator action, since editing the file would allow you to run ikiwiki as any user. What about a user-subdirectory mechanism for this? If each user could have their own `/etc/ikiwiki/users/$user/wikilist`, which only contained wikis (no users), `ikiwiki-mass-rebuild` could rebuild each wiki in this list as the corresponding user only. This would mean that an administrator need only create the directory and provide user or group write permission, and the user or group can then create wikis as needed. + +[[todo/Done]], though somewhat differently. --[[Joey]] diff --git a/ikiwiki-mass-rebuild b/ikiwiki-mass-rebuild index 7ec41e98f..5b6a90b90 100755 --- a/ikiwiki-mass-rebuild +++ b/ikiwiki-mass-rebuild @@ -1,29 +1,80 @@ -#!/bin/sh -set -e +#!/usr/bin/perl +use warnings; +use strict; -action="$@" +sub processline { + my $user=shift; + my $setup=shift; + + if (! getpwnam("$user")) { + print STDERR "warning: user $user does not exist\n"; + return + } + if (! -f "$setup") { + print STDERR "warning: $setup does not exist, skipping\n"; + return; + } + print "Processing $setup as user $user ...\n"; + # su is not used because it passes arguments through the shell, + # which is not safe for untrusted setup file names. + defined(my $pid = fork) or die "Can’t fork: $!"; + if (! $pid) { + my ($uuid, $ugid) = (getpwnam($user))[2, 3]; + $)="$ugid $ugid"; + $(=$ugid; + $>=$uuid; + $<=$uuid; + if ($< != $uuid || $> != $uuid || $( != $ugid || $) ne "$ugid $ugid") { + die "failed to drop permissions to $user"; + } + %ENV=(); + $ENV{HOME}=(getpwnam($user))[7]; + exec("ikiwiki", "-setup", $setup, @ARGV); + die "failed to run ikiwiki: $!"; + } + waitpid($pid,0); + if ($?) { + print STDERR "Processing $setup as user $user failed with code $?\n"; + } +} -wikilist=/etc/ikiwiki/wikilist +sub processlist { + my $file=shift; + my $forceuser=shift; -processline () { - user="$1" - setup="$2" - - if [ -z "$user" ] || [ -z "$setup" ]; then - echo "parse failure in /etc/ikiwiki/wikilist, line: '$user $setup'" >&2 - exit 1 - fi - - if [ ! -f "$setup" ]; then - echo "warning: $setup specified in /etc/ikiwiki/wikilist does not exist, skipping" >&2 - else - echo "Processing $setup as user $user ..." - su "$user" -c "ikiwiki -setup $setup $action" - fi + my $list; + open ($list, "<$file") || die "$file: $!"; + while (<$list>) { + chomp; + s/^\s+//; + s/\s+$//; + next if /^#/ || ! length; + + if (/^([^\s]+)\s+([^\s]+)$/) { + my $user=$1; + my $setup=$2; + if (defined $forceuser && $forceuser ne $user) { + print STDERR "warning: in $file line $., attempt to set user to $user, but user forced to $forceuser.
