Sorry,I can't get this sentence's exact meaning. 'External storage stores page text on a separate DB server to the main wiki database.'
What 's separate DB server ? Or I just want to know where can I get the page content?

It is evaluated during every diff view by comparing (diffing) the two revisions (see phase3/includes/diff/*.php). Note you can view differences between two non-consecutive versions (indeed, you can compare two revisions not even belonging to the same page, e.g. http://en.wikipedia.org/wiki/?diff=12345&oldid=67890&diffonly=1). > I want to see the content(BLOB) of old_text fiels in text table. > What should I do? It depends on the configuration of your wiki. The “text” table might contain the wikitext directly in the “old_text” column (in the source text form, or as a serialized PHP object, see phase3/includes/HistoryBlob.php), or the “old_text” column is only a pointer to where/how the text is really stored, see e.g. http://www.mediawiki.org/wiki/Manual:External_Storage -- [[cs:User:Mormegil | Petr Kadlec]] _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
