#3756 closed defect (duplicate)

Magrating to Trac 0.11 breaks GraphVisPlugin

Reported by: anonymous Owned by: Peter Kropf
Priority: normal Component: GraphvizPlugin
Severity: normal Keywords:
Cc: bill.coffman@… Trac Release: 0.11

Description

We just migrated from 0.10.3 to 0.11.1. Our GraphvizPlugin broke, however. I have updated to the version available at http://trac-hacks.swapoff.org/svn and 0.11 directory the message I get is: Graphviz macro processor has detected an error. Please fix the problem before continuing.

The command
[u'/usr/bin/dot', ”, u'-Tgif', u'-o/var/cache/trac/graphviz/d17c2d792b42ef258cd7d158e8ee3c04ebcb6de8.dot.gif']
failed with the the following output:

Error: dot: can't open

so the seconds parameter in this command is not getting filled with the file name.

If I run the above command with a file containing the contents of my dot file, instead of a blank, it works. So this is just the plugin not getting the file with my dot content.

Another #3605 duplicate, please have a look there for a fix.

Yes, I saw this ticket before.

#3605 looks like some very different behavior though. About the only thing I can see in common is that it's broken after a migration. We have no real error messages, for instance, only the system command can't find the data for the graphviz call.

but comment 2 of #3605 is identical. Thanks for the pointer
