[Pythonsound-devel] Bug fixes against latest CVS

[Paul W. <sli...@ya...>]

Hi Maurizio,

Attached are more doctests and bugfixes against current CVS.
(Wed Oct 10 19:04:17 UTC 2001)

Notes:

- updated everything, including doctests, to use foo.onset() and
foo.duration() as methods instead of attributes.

- Changed several ArgumentError (which is undefined) to ValueError

- Changed disjoint() to not lengthen durations if they were already
short enough.

- Aggregate.duration() was calling Aggregate.move_absolute_forward()
which was broken - it doesn't work to just inherit this from Event.
So I added Aggregate.move_absolute_forward(). In my interpretation,
this should scale the durations of all sub-events by the same ratio,
and adjust their onset times relative to onset of the Aggregate. See
the test examples for an idea of what this does.

- TO DO: look at other move_ methods for Aggregate and see if they
work.

- changed Aggregate to cache end time; it caches onset and duration,
so it seemed consistent to do the same with end.
 
- fixed Aggregate.extend (various errors)

- still haven't tested serialize().

- Aggregate.unwind: changed "unwinded_list" to "unwound"
  ... isn't English fun? :-/

- I assume flatten() is supposed to do the same thing as unwind()?

- changed sort_by_attr to work with new onset0 and duration0
attributes (but not visible to the user).  We should be able to sort
by end() as well, but I haven't looked at that yet so it raises an
error now.
