typo in function caused site to go down

Hello,

Does anyone know what would cause this error?  It took down our site for 4 hours. Notice the typo, "eate_default_timezone_set()" instead of "date"


Default exception handler: Exception - Call to undefined function eate_default_timezone_set() Debug: \n Error code: generalexceptionmessage\n* line 196 of /lib/classes/date.php: Error thrown\n* line 718 of /lib/setup.php: call to core_date::set_default_server_timezone()\n* line 42 of /config.php: call to require_once()\n* line 31 of /mod/quiz/processattempt.php: call to require_once()\n


Is there an easy way to find the code issue?  Is it a Moodle issue?  A Moodle plugin issue?  A PHP issue?

Thanks,

Barbara

Which (exact as you can) version of Moodle is this?

I had a look at that file (lib/classes/date.php) back through a few versions (it's relatively new anyway) and there was no typo.

Presumably you've had a look at line 196 of lib/classes/date.php to see what's there? And...?

Hi Howard,

Sorry I didn't include that to begin with.  We are on 3.4.4 build 20180709.  We are running PHP version 7.1.20 Our server admin looked through the code and didn't see the misspelling anywhere in those files listed.  I could ask him to tell me what line 196 says if that would help.

Thanks,

Barbara

I am in no way technical, so please do not rely on me, but there is a PHP bug going around whereby a letter in  your code is randomly replaced by another letter, and it breaks your site. I am just mentioning it in case that might be the case with you. https://bugs.php.net/bug.php?id=72112 And also https://bugs.php.net/bug.php?id=71135

For Community ref: MDLSITE-5251.

It happens even here in Moodle.org: following the Moodle issue above would be useful for those affected too.

HTH,
Matteo

Thanks Mary and Matteo.  I don't know anything about PHP but will be sharing these links with our team.  We recently upgraded to PHP 7.1.20.  Thank you all for being so helpful.

Hi Barbara, are you able to check with your team what the value is for the PHP setting "opcache.file_cache"?

Hi,

We are (probably) having the same issue with opcache. Additionally, there's a lot of segmentation faults in Apache error log. The errors are gone after disabling opcache.

So the problem seems to be fixed in Moodle.org, and you have opcache enabled? Can you give any details about what has been changed?
