Hello When trying to import an XML file created by "php maintenance/dumpBackup.php --current", I get the following error. What could it mean? Fatal error: Call to a member function getNamespace() on a non-object in /usr/share/mediawiki1.5/includes/Article.php on line 936 I'm running mediawiki 1.5.8 and the export ist from 1.5.6. bye, -christian- -- Christian Hammers WESTEND GmbH | Internet-Business-Provider Technik CISCO Systems Partner - Authorized Reseller Lütticher Straße 10 Tel 0241/701333-11 ch(a)westend.com D-52064 Aachen Fax 0241/911879

The problem was apparently that there was UTF-8 encoded title strings in the XML. To spot such problems I would propose to add some status output similar to: --- includes/SpecialImport.php.orig 2006-06-13 17:00:47.476636412 +0200 +++ includes/SpecialImport.php 2006-06-13 17:03:56.866428299 +0200 @@ -203,6 +203,7 @@ $article = new Article( $this->title ); $pageId = $article->getId(); + printf("Importing %s:%s<br>\n", $this->title->getNamespace(), $this->title->getText()); if( $pageId == 0 ) { # must create the page... $pageId = $article->insertOn( $dbw ); tschüss, -christian- -- Christian Hammers WESTEND GmbH | Internet-Business-Provider Technik CISCO Systems Partner - Authorized Reseller Lütticher Straße 10 Tel 0241/701333-11 ch(a)westend.com D-52064 Aachen Fax 0241/911879

That's normal. Do you mean *non*-UTF-8 encoded title strings? -- brion vibber (brion @ pobox.com)

Sorry for the confusion, what I meant was non-US-ASCII chars like German Umlauts äöüß which were encoded as two-byte UTF-8 chars. Once I changed e.g. "ö" to "oe" in all <title> contents, the import succeeded. Such characters in the body texts were ok, of course. bye, -christian- -- Christian Hammers WESTEND GmbH | Internet-Business-Provider Technik CISCO Systems Partner - Authorized Reseller Lütticher Straße 10 Tel 0241/701333-11 ch(a)westend.com D-52064 Aachen Fax 0241/911879

That's normal then. This should not cause any problems whatsoever.

This should absolutely not be necessary. Are you certain that those characters *were* encoded correctly? -- brion vibber (brion @ pobox.com)

Indeed, some titles had correct UTF8 byte sequences for the German Umlauts and some not: NetzwerkgerÃ€te (0xc3 0xa4 for Netzwerkgeräte - correct) Bï¿œronetz (0xef 0xbf 0xbd for Büronetz - incorrect) bye, -christian- -- Christian Hammers WESTEND GmbH | Internet-Business-Provider Technik CISCO Systems Partner - Authorized Reseller Lütticher Straße 10 Tel 0241/701333-11 ch(a)westend.com D-52064 Aachen Fax 0241/911879
