Hi, I'm using WW on the hosted site. I have a student who can't generate the hard copy for his assignment. In particular, he's getting the message that the set is not assigned to him, although I can "act as" him while logged in as prof and access the problems & hardcopy. I assigned the sets to everyone under the Set Detail, Users Assigned to Set page; his ID is checked.

Here's his error message:

Can't generate hardcopy for set jwilsonjr!HW5-DiscreteRV for user jwilsonjr -- set is not assigned to that user.

Failed to rename 'hardcopy.pdf' to 'EMU_math370.jwilsonjr.jwilsonjr!HW5-DiscreteRV.pdf' in directory '/ww/htdocs/tmp/EMU_math370/hardcopy/work.OC9nQlwV':

Final hardcopy file '/ww/htdocs/tmp/EMU_math370/hardcopy/work.OC9nQlwV/hardcopy.pdf' not found after calling 'generate_hardcopy_pdf': No such file or directory You can also examine the following temporary files: hardcopy.log , hardcopy.aux , pdflatex.stderr , hardcopy.tex , pdflatex.stdout

Any chance the student is logging in with some case variation in his username? We used to get this message a lot in sections where the instructors assigned mixed-case usernames (e.g., JWilsonJR). Login authentication is apparently not case-sensitive (so the student could log in as say, jwilsonjr), but some other functions are case sensitive.

Hi John,

There is a bug in the new version of Hardcopy.pm that was just installed on hosted. We will try to get this fixed quickly.

John,

Is the set in question actually named "jwilsonjr!HW5-DiscreteRV", or is that part of the bug? That seems very odd for a set name.

Hi Sam,

Here is the error message from a course on devel.

# Can't generate hardcopy for set AaronPizer!0 for user AaronPizer -- set is not assigned to that user. # Failed to rename 'hardcopy.pdf' to 'apizer_course.AaronPizer.AaronPizer!0.pdf' in directory '/webwork/shared-courses/apizer_course/html/tmp/hardcopy/work.xD26EeFy': # Final hardcopy file '/webwork/shared-courses/apizer_course/html/tmp/hardcopy/work.xD26EeFy/hardcopy.pdf' not found after calling 'generate_hardcopy_pdf': No such file or directory

I'm now getting the error message below when trying to generate a Hardcopy. I'll investigate and see if I can figure out what's going on; other comments welcome.

The newest version of Hardcopy.pm requires the CPAN module String::ShellQuote.pm

You can find it at

http://search.cpan.org/src/ROSCH/String-ShellQuote-1.03/

You can probably install it using the CPAN module, although I had some difficulty because my index was searching for version 1.02 which has been replaced by 1.03.

It is easy to install by hand.

Ok, the problem is that a new and improved Perl module, String::ShellQuote, is now required for the system. As Mike posted as I posted this.

This was added in version 1.62. Sigh. I guess I figure out what breaks when I back-grade to 1.61 now. I should be able to get the module installed, but I'm unfortunately in a managed environment where I can't just go and install it myself.

I don't think anything will break -- I've actually gone back and forth between Hardcopy.pm 1.61 and 1.62 several times in the last few days as we did the (final?) debugging.
