Error handling when writing to the log file 12 years, 5 months ago #6282

Hi,
I recently installed MJ (v1.0RC4). In trying to set up a test environment with FireFox, I eventually got a "content encryption error" I recovered from that but couldn't then reproduce it! In my experience, this type of problem often traces back to an incorrectly handled fopen() command and so I started looking at those. I found one in plugins/Mobile/terawurfl/TeraWurFl.php and, sure enough, it doesn't allow for the possibility of errors occurring (like the user doesn't have write permission on the file, for example). At line 462, I changed
		$_logFP = fopen($logfile, "a+");
fputs($_logFP, $_textToLog."\n");
fclose($_logFP);
 
to
		$_logFP = @fopen($logfile, "a+");
if (is_resource($_logFP)) {
fputs($_logFP, $_textToLog."\n");
fclose($_logFP);
}
 
I don't know if it is related to the problem I experienced but a bit of defensive coding can't do any harm.
Regards
Phil

MJ disables writing to log file (look at TeraWurflConfig::$LOG_LEVEL=0; in plugins/mobile/terawurfl.php).

I'm not sure what point you are making.
Do you mean that it doesn't matter because it's redundant code?

Yes, we use TeraWURFL library "as is". The library can save some notices to log file, but we disable this feature by assigning zero value to LOG_LEVEL parameter.
