Merge lp:~vds/desktopcouch/again_python_couchdb into lp:desktopcouch

[Vincenzo Di Somma]

Port to use python-couchdb 0.8. This makes future desktopcouch incompatible with previous versions of python-couchdb.

Port to python-couchdb 0.8, to test it download it from here:
http://goo.gl/UDmnx
Unpack and put the couchdb folder in the root of the branch.

[Eric Casteleijn (thisfred)]

looks good to me, tests pass.

review: Approve

[Eric Casteleijn (thisfred)]

We should probably package python-couchdb before we land this though. :(

[Manuel de la Peña (mandel)]

+1, thx!

review: Approve

[Ubuntu One Auto Pilot (otto-pilot)]

Attempt to merge into lp:desktopcouch failed due to conflicts:

text conflict in desktopcouch/records/server_base.py

[Chad Miller (cmiller)]

98 +"""This modules olds some code

?

244 + if isinstance(body, str):

Should this be basestr instead of str? I don't know if Unicode should ever be sent as body, but if it is, should it be treated as a file in "else"?

[Eric Casteleijn (thisfred)]

The deprecated files are still gone, and I get 2 conflicts when merging this branch into trunk.

[Chad Miller (cmiller)]

Natty hackers ppa ready. Let's land this!
