Unable to Scribunto/Lua working on our wiki. Getting the following error:
Fatal error: Call to undefined function pcntl_wifsignaled() in/home/jackdl5/public_html/jurassicoutpost.com/encyclopedia/extensions/Scribunto/engines/LuaStandalone/LuaStandaloneEngine.php on line 645Fatal error: Call to undefined function
Permissions for the Engine binaries are all set correctly and both Scribunto and Lua show as being installed on Special:Version.
Any thoughts?
pcntl_wifsignaled() is a PHP function, that needs to be installed/enabled on the server, although it's not listed as a requirement in Extension:Scribunto. I wonder how many shared host provide that requirement.
Because we're on a shared server our host is telling us it's not possible to get this set up, is there another work around?
The alternative to luastandalone is luasandbox, but that requires even more influence on the php server I believe.
Would using an older version pre-May 2015 help combat this issue for now?
Apparently this is a known issue logged as phab:T128048. It links to a proposed patch, that has not fully been tested yet, that might workaround this.
Believe it or not that actually worked! Pages are loading again, but I'm getting this error now:
Lua error: Internal error: The interpreter has terminated with signal "11".
Next step?
I'm glad it worked for you.
Re: Signal 11:
I'm going to guess that the wrong lua binary is being used. Hmm... Do you have shell access to the machine? Can you run "uname -a" and paste the result here?
Alternatively, if you can create a phpinfo page and copy-paste the result, that may help.
Whoops, meant this... http://jurassicoutpost.com/encyclopedia/phpinfo.php
