Item13327: Deep recursion at wrong web rename

Deep recursion at the web rename

How to reproduce

  • Create web Tutu
  • Go to WebPreferences
  • click rename web
  • set the new name to Tutux
  • Choose the new parent itself (Tutu)
  • click rename

Page long error message to user, and in the log:

[Tue Mar 24 22:31:12 2015] rename: Caught Deep Recursion Condition: /me/fw/utest2/foswiki/core/data/Tutu contains /me/fw/utest2/foswiki/core/data/Tutu/Tutux at /me/fw/utest2/foswiki/core/lib/Foswiki/Store/ line 1313.

Of course, it is a stupidity trying rename and set the parent itself, but in the drop-down should not be shown itself's name - in this case Tutu.

I've added a check in UI::Rename to prevent setting the new parent to either the old or new webname. It's not as easy to remove the current web from the parent list. it would require adding a new parameter to the WEBLIST macro - to exclude the current web. And it wouldn't cover the case of trying to set the parent to the new webname.
