PHP safe mode

[Xavier]

Am I correct in assuming that phpFreeChat does not work in safe mode? Running the script seems to generate a lot of errors related to file operations. Is there a way to work around this?

[phpfreechat]

Yes it's known pfc has problems with "safe_mode=On"
I don't have time to look at workerounds but I will be pleased to integrate any patch attempt to fix this problem.

I'll take a look, but if the script relies heavily on file operations there isn't much I can do. Too bad, this is by far the most promising chat script I've seen.

Anyway, I'd suggest adding a mention about safe mode to the required configuration page.

Could you test the Memory container ? (demo35)
maybe it works better with safe_mode enable

[phpfreechat]

I just tested the chat with safe_mode enable on my localhost.
It works but I need to give all scripts the servers "user:group" rights.

On my debian I typed these lines to install the chat :

Code: Select all

cd ~/public_html/tmp/
wget http://www.phpfreechat.net/download/phpfreechat-0.9.1.tar.gz
tar xzf phpfreechat-0.9.1.tar.gz
chown -R www-data:www-data phpfreechat-0.9.1

Then I just browsed to my localhost url : http://localhost/~kerphi/tmp/phpfreechat-0.9.1/

It works well without any warnings or errors ...

However the shared memory container doesn't works well because of my local pear installation, I got :

Warning: main(): SAFE MODE Restriction in effect. The script whose uid is 33 is not allowed to access /usr/share/php/PEAR.php owned by uid 0 in /home/kerphi/public_html/tmp/phpfreechat-0.9.1/lib/pear/System/SharedMemory/Shmop.php on line 41

Warning: main(PEAR.php): failed to open stream: No such file or directory in /home/kerphi/public_html/tmp/phpfreechat-0.9.1/lib/pear/System/SharedMemory/Shmop.php on line 41

Fatal error: main(): Failed opening required 'PEAR.php' (include_path='.:/usr/share/php:/usr/share/pear') in /home/kerphi/public_html/tmp/phpfreechat-0.9.1/lib/pear/System/SharedMemory/Shmop.php on line 41

Hope that helps.

Yes, that would probably to the trick, but unfortunately I'm not a root user so chown is out of the question.

I tried to recreate the directory structure manually, but the script kept dying with:

Warning: main(): Unable to access xajaxResponse.inc.php in lib/xajax_0.2.3/xajax.inc.php on line 39

Warning: main(xajaxResponse.inc.php): failed to open stream: No such file or directory in lib/xajax_0.2.3/xajax.inc.php on line 39

Fatal error: main(): Failed opening required 'xajaxResponse.inc.php' (include_path='') in lib/xajax_0.2.3/xajax.inc.php on line 39

...until I fixed the require_once("xajaxResponse.inc.php"); by entering the full path of the xajaxResponse.inc.php file. Works like a charm. Yay!

Ok thank you for the tip, I integrated this patch to the pfc source code :

my server does not have deactivated "safe mode", I have option to use this chat anyway?

Tnx!

[phpfreechat]

Just try, in certain configuration pfc will works (when I enable safe_mode on my localhost, I don't have any problems) but on some strange configuration it doesn't works ...
