[ppa-dev] Ubuntu suckage?

[Karl O. P. <ko...@me...>]

Regards an annoying session log message,

(I wonder if this is just an Ubuntu problem....
Probably.)

Putting my notes here, in case they're useful.

[16:41:29]<karlpinc> I am, FYI, seeing this bug on Ubuntu Lucid LTS:  
[Fri Oct  
                     26 17:05:48 2012] [error] [client 68.34.81.88] PHP 
       
                     Notice:  session_start(): ps_files_cleanup_dir:    
       
                     opendir(/var/lib/php5) failed: Permission denied 
(13) in   
                     /srv/var/www/https/phpPgAdmin-head/libraries/
lib.inc.php   
                     on line 56, referer: 
[16:43:25]<karlpinc> The probem is that the session is timing out and 
the OS    
                     is not giving php x permission on the directory 
where      
                     state is stored.  This is probably appropriate for 
the     
                     OS, but we get this message.
[16:44:52]<karlpinc> It's not clear to me what can be done in ppa.  I'm 
       
                     thinking the solution is for ppa to have it's own 
login    
                     timeout that's significatly shorter than the php 
session   
                     timeout/garbage collection....  Any good ideas?
[16:48:56]<karlpinc> We should at least have something in the FAQ and 
give      
                     people some guidance.

Google sez:
http://steffe.se/?p=474
Which says to put an @ in front of the session_start(),
which is totally the wrong thing to do.

http://vvv.tobiassjosten.net/php/php-session-garbage-collection/
Has a nice analysis, and suggests turning off session garbage
collection, which is also ungood.
