### Webwork errors when submitting a problem

by Lars Jensen -
Number of replies: 5
We're getting the following error when clicking the submit button. I first thought it had to do with a wrong symbolic link, but haven't been able to find one... Any ideas what might cause this? It looks like webwork is trying to create the log directory in the wrong spot...

We're running the latest CVS as of a few days ago.

Thanks,
Lars.

Argh :-) -- this is bug #1133. Make this modification to your global.conf file where it defines the location of the transaction log.
 # The transaction log contains data from each recorded answer submission. This
# is useful if the database becomes corrupted.
# I changed this to log to the system logs directory to work around a
# bug in surePathToTempFile.
$webworkFiles{logs}{transaction} = "$webworkDirs{logs}/$courseName.transaction.log";  I've placed this hack in the CVS version of global.conf.dist for now until someone has time to make a permanent fix. (Read the notes in bug #1133 before jumping into the fix -- there are some delicate spots. ) In reply to Michael Gage ### Re: Webwork errors when submitting a problem by Lars Jensen - Hi Mike, Thanks! -This worked, but only after commenting out the line:$courseDirs{logs}        = "$courseDirs{root}/logs"; I assume this is needed too.

That causes the path to the login.log to be right under the root directory when it should be under the course directory. WeBWorK now also thinks the transaction.log has a complete path of /transaction.log right under the root directory, which is clearly not what you want. You want the transaction.log to be in ....webwork2/logs/transaction.log$webworkDirs{log} should give you webwork2/logs if you
trace it through in global.conf. At the moment it seems to be undefined in your case. Perhaps there is a semi-colon out of place in the global.conf file?

Hope this helps.

Take care,

Mike

Hi Mike,

Sorry - I edited the wrong area of my global.conf. Instead of editing the "Logs" section, I edited the transactions logs section of the "Defaults for course-specific locations" area. Everything us OK now. Thanks for your help.

Lars.
