Description
I just did a title search with the xapian search enabled and receive an IndexError list index out of range. If i doing the same search on another wiki instance (also with the same xapian search and wiki version (farmwiki) ) the error not occur! Rebuilding manual the Index helps!
Interesting is only that the SystemInfo shows up that everything with the xapian (and also the index) is ok. I also received this error not the first time! it's comming and going.. every few weeks, i guess!
Steps to reproduce
- not possible due the rebuild of the index
Example
Component selection
- xapian, index

Discussion
Maybe, somebody could explain this error to me? Thanks!
I just got the same error on my machine. I am running RHEL 5, Python 2.4, Xapian 1.0.4 (no PyStemmer), MoinMoin 1.6.1, all in EN. I hope this gets fixed soon! --counterpoke
- Okay, so I edited the following lines:
page = Page(self.request, pagename, rev=revision) if not self.historysearch and revision and \ page.getRevList()[0] != revision:topage = Page(self.request, pagename, rev=revision) revs = page.getRevList() if revs != []: if not self.historysearch and revision and \ revs[0] != revision: continueand this seems to have "fixed" the issue. It was because some pages were returning "[]" for getRevList. This is a hack though. I don't exactly know if getRevList is supposed to return empty arrays... --counterpoke
Thanks for the patch. I think it happens when pages that got indexed a while ago match the search query, but someone renamed or nuked the pages after the index was built - so there are no revisions there any more. -- ThomasWaldmann 2008-05-03 17:43:55
