Subject [jira] Commented: (JSPWIKI-352) page ACLs seem to get mixed up in special cases
Date Wed, 20 Aug 2008 20:50:44 GMT

    [ https://issues.apache.org/jira/browse/JSPWIKI-352?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12624131#action_12624131

Andrew Jaquith commented on JSPWIKI-352:
----------------------------------------

Nooooooooo.... REALLY? The patch is so trivial! 

But the realPage/page properties have always been part of JSPWiki's Deeper Voodoo, and I confess
I don't understand their real function. Janne, can you explain this a bit more? Why does this
fix work?

> As reported on the mailing list before, I had some weird issues with pages getting uneditable
as if by a ghost's hand.
> I was able to reproduce this error finally like following:
> Insert the page ACL "allow view all" to the page named "EditPageHelp" (and verify there's
no other ACL).
> Seems as if editing an arbitrary page after this, the page ACLs of the page to be edited
and the EditPageHelp are getting mixed up somehow. The result is, that pages aren't editable
at all (although they should be), or that there's an error while saving the changes ("you're
not allowed to do that, better luck next time") and the page becomes uneditable from this
moment on.
> I didn't track it down to the source code, but I think this will be quite easy now.
> Also, I didn't test older releases, only the 2.7.x (current trunk).
> Interesting to see that some pages only become uneditable only after trying to edit them,
while others are uneditable from the beginning on. Maybe the pattern can be checked while
debugging in order to get some hints for JSPWIKI-27.
> Happy debugging!
