[HTCondor-users] python bindings: how to get history iterator?

[Thomas Hartmann <thomas.hartmann@xxxxxxx>]

Hi all,

I am currently struggling to go through the Python bindings for my 
schedulers' histories. According to the documentation [1], 
scheduler.history() should return an iterator over historic job ads. 
However the function fails with [2] for me.
But without arguments, the function should be projecting all ads for all 
jobs (up to a rate limit), or?

To avoid any problems, I am querying the scheduler on the collector 
machine itself, where the installed packages look like [3].

Maybe somebody has an idea for me, how to properly get the historic ads?

Cheers and thanks for ideas,
  Thomas
