1. Merge local changes with changes from other specified MediaWikis

  1. Get items in global changes-cache

  $changes = array(); $tr = 999; foreach (array($GLOBALS['IP'].'/Global.changes', $GLOBALS['IP'].'/'.$GLOBALS['xwUserName'].'.changes') as $cache) if (file_exists($cache)) foreach (file($cache) as $change) { $change = split("\\|",trim($change)); $change[2] = split(',',$change[2]); $change[2][0] = str_replace('Energy Alternatives','EA',$change[2][0]); $change[2][0] = str_replace('Azzuro Workgroup','AWG',$change[2][0]); $change[2][0] = str_replace('JewelWiki','JW',$change[2][0]); $change[2][0] = str_replace('GeeXboX wiki','GeeXboX',$change[2][0]); $change[2][0] = str_replace('Organic Design','OD',$change[2][0]); $change[2][0] = str_replace('OrganicDesign','Closet',$change[2][0]); $change[2][0] = str_replace('SourceryForge','✿',$change[2][0]); $change[6] = preg_replace("/\\w+:\\w+@/","",$change[6]); $changes[(strtotime(array_shift($change))+3600*intval(array_shift($change))).'.00'.$tr--] = $change; } }

  1. Get the list of wikis for which changes are merged

  $wikis = array();

  1. if (!$wl = xwArticleContent($GLOBALS['xwUserName'].'/wiki.list',false)) $wl = xwArticleContent("$tTitle/wiki.list",false);
  2. if (preg_match_all("/^\\*.*?\"(.*?)\".*?\"(.*?)\".*?\"(.*?)\".*?\"(.*?)\"/m",$wl,$wikis,PREG_SET_ORDER))
  3. for ($i = 0; $i < count($wikis); $i++) array_shift($wikis[$i]);
  1. Merge each wikis changes into local table
  2. - connect with socket so we can bail after a small timeout

  if (!$qs = $_SERVER['QUERY_STRING']) $qs = "title=Special:Recentchanges"; # same QS for remote requests $changes = array(); foreach ($wikis as $wd) {

     $url = parse_url($wd[1]);
     $domain = $url['host'];
     $scheme = $url['scheme'];
     $port = $scheme == 'http'?80:443;
     $request = $url['path']."?$qs&xpath://view:=&printable=yes";
     if (0 && $handle = @fsockopen($domain,$port,$errno,$err,1)) {
         fclose($handle);
         extractChanges($changes,file_get_contents("$scheme://$domain$request"),$wd);
         } else xwMessage("Failed to merge changes from $scheme://$domain",'red');
     }
  

  1. Merge the local changes

  extractChanges($changes,$article);

  1. Render all changes

  if ($swf = $_REQUEST['SWF']) { $i = -1; $html = ; ksort($changes); foreach (array_reverse($changes,SORT_STRING) as $t => $c) { $time = strftime('%H:%M', $t); if ($wt = $c[0][0]) { $key = "<a href=\"".$c[0][1]."\">$wt:</a>"; $col = '#009900'; } else { $key = $c[5]; $col = '#000080'; } if (!ereg('m',$c[3])) if ($i++<9) $html .= ($i?'&':).str_replace('&','%26',"item$i=$t,$time,$key,$c[4],$col,$c[7]"); } ob_end_clean(); header('Content-type: application/x-www-urlform-encoded'); print $html; if ($_REQUEST['INFO']) print '&user='.$GLOBALS['xwUserName']; die; }

  else $article = preg_replace( "/

  [0-9]+ [a-z]+ [0-9]+<\\/h4>\\s*

  .+(?=
  )/ise", '"
  ".renderChanges($changes)',$article);

  1. Remove space-wasting text and change title

  if ($title == 'Special:Recentchanges') {

  #$article = preg_replace('/(?<=

  ).+(?=<\\/h1>)/', 'Recent changes (see also <a href="/news">news</a>)', $article); $article = preg_replace("/

  Track the most recent changes.+(Below are the last)/s",'$1',$article); # Add show/hide-external link $link = $_REQUEST['hideexternal'] ? '&hideexternal=0' : '&hideexternal=1'; $anchor = $_REQUEST['hideexternal'] ? 'show' : 'hide'; if (preg_match('/my edits\\s*<br/',$article)) $anchor = ucwords($anchor); $article = preg_replace('/( patrolled edits\\s*)|( my edits\\s*)(?=<br)/i',"$1$2 | <a href=\"$script?title=$title$link\">$anchor</a> external changes",$article); } else if ($title == 'Special:Contributions') { $user = str_replace('User:',,$_REQUEST['target']); $article = preg_replace('/(?<=

  ).+(?=<\\/h1>)/', "<a href=\"/user:$user\">$user</a>'s contributions", $article); } ?>
