Re: [xwiki-users] unable to import big xar file

Hello, i am migrating a small wiki that is expected to grow in the future (more pages, more documents). Currently, the wiki is small, the xar is about 50M. To my surprise, xwiki was unable to load it with 1G heap space. Actually, it consumed 2.5G memory just to upload this xar, which make a ration of 50x (a big problem by itself). And then, when i select this archive, i am greeted with "There was an error reading the file MainWiki.xar. Truncated ZIP file" and the error below in the console. What is the recommanded way to some pages from an existing old xwiki to another more recent xwiki since the xar is not working? Is there some plan to recode this xar importer so that it becomes far less greedy? 08:17:52,271 INFO [stdout] (http://intraweb-me.oma.be:10080/xwiki/bin/import/XWiki/XWikiPreferences?edi…) 2012-07-05 08:17:52,271 [http://intraweb-me.oma.be:10080/xwiki/bin/import/XWiki/XWikiPreferences?edi…] WARN c.x.x.p.p.Package - Failed to parse document [XWiki/XWikiAdminGroup.xml] from XML during import, thus it will not be installed.
