[pmwiki-users] Bugreport: Save fails (content destroyed) due to filled quota

[Jochem Liem]

Dear developers,

I put a new bug in the bugreport system:
http://www.pmwiki.org/wiki/PITS/01057

Summary: Save fails (content destroyed) due to filled quota

Version: 2.1.27
OS: SunOS mremote 5.9 Generic_122300-16 sun4u/Apache/1.3.37 (Unix) 
PHP/4.4.4 mod_ssl/2.8.28 OpenSSL/0.9.8d

Description: Saving a wiki page when the webserver quota is full causes 
the wiki page save to fail. The file is saved with size 0, thus 
destroying all content.

The content of the following files was lost (given size 0): 
~/public_html/pmwiki/wiki.d/Main.HomePage 
~/public_html/pmwiki/wiki.d/Main.RecentChanges 
~/public_html/pmwiki/wiki.d/Site.AllRecentChanges

To reproduce: 1. Create a wiki page with content 2. Fill the quota of 
the webserver user (or maybe fill the partition?) 3. Try to modify and 
save the wiki page.

Result: Content (and all changes) are lost and the wiki page file gets 
size 0. The content cannot be recovered by reverting, since the 
RecentChanges and AllRecentChanges files are lost too.

Desired result: The save should fail with an error message and the 
original content should be preserved.

Note: Unfortunately, I'm unable to check this problem (with the latest 
version of PMwiki), since I'm on a shared university network. Filling 
the quota (of the webserver user) would break all the Wiki's/Blogs/CMS 
systems on the webserver.

Thank you very much for an excellent product. I absolutely love pmwiki 
with jsMath. :)

Best regards,
Jochem Liem
