Actually I am not so fast, as you see.. All the steps mentioned above are passed successfully. No wonder, because I've used to install SMW0.6 and SMW0.7 previousely, and the later one runs fine on my site. > Since you're having problems with categories (see later), try making a > few nested subcategories and doing queries on them. > I don't know if the old backups are compatible.

Yes, I've executed SMWAdmin before the XML restore. It worked fine. I do not trust upgrade scripts, I feel they are more vulnerable to bugs comparing to XML backups. >Error in fetchObject(): Table 'yarsu.cats4' doesn't exist (127.0.0.1) > I think "catNNN" are temporary tables that SMW creates in > getCategoryTable() when it makes "a (temporary) table that contains the > lower closure of the given category wrt. the category table."

Database permissions are SELECT, INSERT, UPDATE, DELETE, CREATE, ALTER, LOCK TABLES These were enough for SMW 0.7. And yes, I've restored the XML backups with older versions. Though, I realize that the difference between 0.7 and 1.0 is much wider. > What PHP and MySQL versions are you running? PHP 5.2.4 and MySQL 5.0.45, accordingly. Works with MW 1.10/SMW 0.7 just fine. When I've used to install 1.93/SMW 0.6 some time ago, I've had a major screwup with mysql RPM, which installed by default with charset settings ISOsomething instead of unicode. Since then, I implicitely specify UTF8 as default charset. > In the failures you attached, the MediaWiki import script is parsing the > XML of a page that apparently has an inline query in it, so it's > calling smwfProcessInlineQuery() > Can you try making a simple query for a category from Special:Ask?

I've added CREATE TEMPORARY TABLES to mysql priviledges and now it imported the rest of the dump just fine, too. But, I wasn't happy for a long time. An attemnt of executing Special:Ask page results with httpd consuming 99% of CPU infinitely, until I shutdown it and restart :-( Will investigate further tomorrow...

As someone with no backup to speak of nor a SMW lead developer, it sounds like the best thing to do is to restore the backup into the version it was taken from, and then use the built-in upgrade system to live upgrade between point releases of SMW/MW to upgrade your data format. -- Asheesh. -- A diplomatic husband said to his wife, "How do you expect me to remember your birthday when you never look any older?" - This SF.net email is sponsored by: Splunk Inc.

I don't know if the old backups are compatible. With each SMW and MediaWiki update I made a backup but I made the upgrade in-place and ran the updates scripts and SMWAdmin with no incident, so I never had to try the backups. So everything I write is guessing 8-/ Error in fetchObject(): Table 'yarsu.cats4' doesn't exist (127.0.0.1) I think "catNNN" are temporary tables that SMW creates in getCategoryTable() when it makes "a (temporary) table that contains the lower closure of the given category wrt. the category table." I'm not sure why it's failing. It could be a database-level problem, such as a permissions issue. What PHP and MySQL versions are you running? If you can make a smaller XML file that fails to import, you can modify MediaWiki's LocalSettings.php to turn on extra SQL logging, for example: ## === from http://meta.wikimedia.org/wiki/How_to_debug_MediaWiki === /** * The debug log file should be not be publicly accessible if it is used, as it * may contain private data. */ $wgDebugLogFile = 'mediawiki_debug_log.txt'; # Override DefaultSettings.php $wgShowSQLErrors = true; ## === from http://www.mediawiki.org/wiki/Manual:%24wgDebugDumpSql $wgDebugDumpSql = true; and send part of the log file.

I would remove anything that has an query in it, and/or anything that has the mysterious extension or template that's generating the class="tbl stuff.

[SMW-devel] restoring XML backup
Hi!
Are the old MW 1.10/SMW 0.7 XML backups compatible with
MW 1.11/SMW 1.0RC1? I am trying to import my backup into the new
installation, but it throws such error (smw_error1.txt).
After that, I've decided to remove all the Attribute:
namespace pages from the dump. Drop all the tables,
recreate the /config, do Special:SMWAdmin, now it throws another
error (smw_error2.txt)
Next, I've removed Relation: namespace pages from the dump.
Now it produces the following error (smw_error3.txt)
