[Phpwiki-talk] URGENT: BUG FIXED in 1.2 CVS, caused on Dec 2

[Carsten K. <car...@ma...>]

Today I discovered and fixed a HUGE bug in the 1.2 branch, which I 
inadvertently caused on December 2 and 3. :-(

Everyone who downloaded from the 1.2 branch CVS on or after December 2 
should download the fixed version of stdlib.php from the CVS AS SOON AS 
POSSIBLE.

**********************************************************

The bug was created when I added the split_pagename function (and the 
optional autosplit wikiwords).

The problem occurs when clicking on any "EditPage". After saving the page,
  the new data would be incorrectly saved with a space in the page name. So,
  if you were editing "TestPage" a NEW page would be added called 
"Test%20Page".

If you DID NOT download PhpWiki 1.2 on or after Dec 2. then you will not 
be affected.
If you are not sure, there is a way to determine whether your data has 
been affected by this bug:

1. Open /lib/stdlib.php. search for "split_pagename".
2. If you find this function in your stdlib file then you are probably 
affected.

To determine the extent of the damage:

1. Perform a ZIP dump of your phpwiki database
2. Open the ZIP file, and look for duplicate pages, ones without %20 in 
the name and the same page name again with %20.

Unfortunately one cannot do a title search for " " or %20.

If you do have duplicate pages, the %20 version will be the most recent 
version.

To fix the affected pages:

1. Download the corrected stdlib.php from the CVS.
2. Edit the affected page(s) (e.g. Test%20Page)
3. Copy all the text
4. Edit the correct page (e.g. TestPage)
5. Paste in all the text
6. Delete the bugged page (e.g. Test%20Page)
7. Repeat for all affected pages.

I am sorry for any problems this has caused. Please contact me if this bug 
caused you problems, I will do my best to help fix it.
