Bug Description

Each time the dsc file changes here's what happens :

$ falcon scan
Falcon repository manager 2.0.1 (C)2005-2008 Dennis Kaarsemaker <email address hidden>
* Scanning component 'gutsy/main'
W: Source package ardour_2.1+svn2830-ematech1.dsc changed after installing

 === ERROR! ===

An error occured in falcon. This is probably a bug in the software.
Please file a bug at https://launchpad.net/falcon/+filebug and
include the following backtrace:

Traceback (most recent call last):
  File "/usr/bin/falcon", line 235, in ?
    component.scan(clean = action=='clean')
  File "/usr/lib/python2.4/site-packages/falcon/plugin.py", line 155, in wrapped_func
    result = func(*args, **kwargs)
  File "/usr/lib/python2.4/site-packages/falcon/pocket.py", line 184, in scan
    newfiles = s.rescan()
  File "/usr/lib/python2.4/site-packages/falcon/package.py", line 189, in rescan
    self.packagename = controlfields['source']

I workaround this by clearing the "falcon_sourcepackage" table in the sqlite3 database.

you missed the most important part of the backtrace: the actual error :)

I think I found the bug though, there was a comma that shouldn't be there, please test with falcon 2.0.2, which will be released later today.

Whoops. You're right!
The error was :

NameError: global name 'controlfields' is not defined

I'll test your fix as soon as I can, thanks!

The fix didn't work and fixing it properly uncovered another bug. I'm debugging that now.

A whole mess wass uncovered (a part that was never properly ported to the falcon 2.0 architecture), I rewrote the rescanning logic and it works fine now. Tested with your ardour package and another small one.

Fixed for me in the 2.0.2 release. Thanks a lot!

Thanks for testing! If you ever need to reinitalize your repo or create a new one, please upgrade to 2.0.3, 2.0.2 and prior have a nasty bug with initial setup which you won't see on existing repositories.
