desktopcouch applications throw 401 error

Note that this occurs on brand new code, essentially creating a new CouchDatabase like this:
self.__database = CouchDatabase(self.__db_name, create=True)

I also got the same error trying it directly in iPython:

In [3]: import desktopcouch.records

In [4]: desktopcouch.records.server.CouchDatabase("foob")

Tried with first install of Desktop couch, get NoSuchDatabase() exception

I can't confirm this, the same test worked for me with desktopcouch = 0.4.4-0ubuntu1

OK, after a reboot today I can reproduce this. My log files also have 401 errors for each attempt to access the url.

I think the cause of this was fixed two weeks ago. I expect that the only people who will experience this problem are people who had v0.4.2 of desktopcouch installed and ran the desktopcouch-pair tool and changed the number of peer pairings.

That would read in the desktopcouch INI file, change the server bind-address, and write out the config file again. During that update, the Python ConfigParser class would crush keys to lowercase, including OAuth token values.

message:
  Do not let Python's ConfigParser transform options into lowercase, as
  couchdb options are case-sensitive.

The easy work-around for this bug is to remove the INI file and let it be created again when desktopcouch starts.

Without rebooting:
$ killall desktopcouch-service
$ /usr/lib/desktopcouch/desktopcouch-stop
$ mv ~/.config/desktop-couch/desktop-couchdb.ini{,-broken-by-lpbug451809 }

I'm going to close this bug, with the assumption that it happens only to a small fraction of beta users, and that that workaround fixes it. Please re-open it if there are any exceptions to those assumptions.

I was getting errors very similar to these. I discovered I had old launchpadlib and oath libs in /usr/local/lib/python2.6. Removing them allowed couch to start and now I can use gwibber and UbuntuOne

I don't think this is valid any more. Lucio, who re-opened this, plans to look for this again. Comment 6 has how to revert bad data in ones config.

there seems to be quite a few people facing this issue.

or not people actually get raise ServerError((status_code, error)) ServerError: (400, '')

I faced this issue with my program too.
Database created but server returns 400 error code.
To reproduce this issue you can delete database, which application used.

I catch this bug on ubuntu 10.10 with
desktopcouch:
  Installed: 0.6.6-0ubuntu3
  Candidate: 0.6.6-0ubuntu3
  Version table:
 *** 0.6.6-0ubuntu3 0
        500 http://archive.ubuntu.com/ubuntu/ maverick/main i386 Packages
        100 /var/lib/dpkg/status

but after
$ killall desktopcouch-service
$ /usr/lib/desktopcouch/desktopcouch-stop
$ mv ~/.config/desktop-couch/desktop-couchdb.ini{,-broken-by-lpbug451809 }
it works

Expiring incomplete bug after a lot of time of inactivity. Please reopen if still valid.
