Error messages

[Jeffrey Micher]

As I'm working through trying to learn ducttape, I'm getting some error messages that I don't understand.  I tried 1 simple workflow, then edited it to name the output file with a name of choice rather than with the name of the variable.  So that I would start fresh, I removed the directories from the previous run. I rerun the tape, and I get:

So, I looked in /home/jmicher/canonical/.. and there is no ./versions directory.  So I don't know where it is to delete it.

 

Also, any idea why I'm getting stdout containing things starting with ^[[ ?

Just to be sure this isn't a simple error, ducttape would have created a ./.versions directory, not a ./versions directory.  Did you look for ./.versions, and just type it wrong in your email, or did you only look for ./versions?

I copied and pasted the error message.  I did find the .versions directory and deleted it.  Ran again and it worked.  But then I edited my tape file and ran it again and got the same message.

 

So the question I guess is: what should the procedure be when incrementally developing and testing a .tape file (to avoid getting errors)?

Hi Jeff,

This was a bug in v0.3-pre1. Downloading v0.3-pre3 should fix the crashing issue.

The ^[[ lines are ANSII color codes, which will display fine on most interactive Linux consoles. You can disable them with --no_color.

In general, if you want to modify a task after it has been run successfully, rather than delete stuff ducttape has generated you can invalidate a result—something like:

$ ducttape workflow.tape invalidate task '*'

where 'task' is the task you want to invalidate.
