Item11981: USERINFO: broken with FastCGI and {AntiSpam}{HideUserDetails}

Priority: Urgent
Current State: Closed
Released In: 1.1.6
Target Release: patch
Applies To: Engine
Component: USERINFO
Branches: Release01x01 trunk
Reported By: JanKrueger
Waiting For:
Last Change By: GeorgeClark
On servers that use FastCGI or something similar, the USERINFO macro is too enthusiastic about cloaking data. This is because the variable that controls cloaking is only set in one branch of the code (USERINFO macro with a username arg passed to it). Hence, all future calls of USERINFO without a username arg will be cloaked, too; this breaks saving topics in our setups (among other things).

How to reproduce (probably)

  • Turn on $Foswiki::cfg{AntiSpam}{HideUserDetails}.
  • Set up FastCGI.
  • Log in.
  • Use a %USERINFO{"someusername"}% macro somewhere.
  • Within the same FastCGI process, use a %USERINFO% macro (or %USERNAME%).

How to fix

Here's a diff (against an arbitrary version, but should be easy to apply it manually if necessary):
