Question

I am using subwebs for my wiki and have discovered there seems to be a problem with webview/change/rename permissions. Basically, if I look at the TWiki/SitePermissions page I can quickly see that the SubWebs are inheriting the web permissions from the parent web regardless of what is listed within the SubWeb's WebPreferences. However, other WebPreferences are being set uniquely for the SubWeb.

Has anyone else run into this or no the solution?

This site is running TWiki version Wed, 08 Feb 2006 build 8740, Plugin API version 1.1

Environment

Here is a snip from the Web & SubWeb WebPreferences: OurMainWeb

• • #Set DENYWEBVIEW =
  • Set ALLOWWEBVIEW = OurGroup
  • #Set DENYWEBCHANGE =
  • Set ALLOWWEBCHANGE = TWikiAdminGroup
  • #Set DENYWEBRENAME =
  • Set ALLOWWEBRENAME = TWikiAdminGroup

SubWeb1 * #Set DENYWEBVIEW =

• • Set ALLOWWEBVIEW = Main.sacaske
  • #Set DENYWEBCHANGE =
  • Set ALLOWWEBCHANGE = TWikiAdminGroup
  • #Set DENYWEBRENAME =
  • Set ALLOWWEBRENAME = TWikiAdminGroup

SitePreferences lists:

(The SITEMAPLIST is off on my subweb in its WebPreferences)

I've started parsing the Prefs.pm and PrefsCache.pm files to get me some more details as STDERR messages. I am showing that the preferences path is set to what I would be expecting (from pushWebPrefernces) and that the Hash has been updated: TWiki::Prefs::PrefsCache=HASH(0x8874844) (eg)

But if I put a print statment inside the ObjectMethod insert within PrefsCache.pm I am seeing all the WebPrefences listed out in my apache log in what appears to be the order Web, SubWeb which means several values are repeated. But I am not seeing the ALLOWWEBVIEW,ALLOWWEBCHANGE, or ALLOWWEBRENAME only TOPIC stuff in the last set of preferences to scroll by.

I'd include the log here, but this chunk is well over 5000 lines, here is just a bit though:

If someone can confirm that my impressions of what I am seeing are correct, I would really be greatful.

Answer

If you answer a question - or someone answered one of your questions - please remember to edit the page and set the status to answered. The status selector is below the edit box.

Well, after setting lots of STDERR messages within the Prefs.pm and PrefsCache.pm file and parsing apache error logs I found the problem. Basically, this message located within the default WebPreference file is not complete:

• Web preferences that are not allowed to be overridden by user or topic preferences:

It should also include SubWebs. Basically, a Subweb can also not overwrite any setting set to final in the top level web. So if you are using SubWebs and need different preferences make sure they are not set to Final in any upper web.

I hope this helps someone else stuck in a similar problem.

I've encountered this as well and I have to say this isn't just an inconvenience, its a bug. If not, its clearly not documented that this is the way you should expect performance and, if it wasn't for all of Susan's work, I'd be sorely out of luck.

Agreed, thanks Susan.
