Cannot getPort - desktop-couchdb.log doesn't exist

[Murat Gunes]

Binary package hint: desktopcouch

With desktopcouch 0.3-0ubuntu1 and bindwood 0.2~~rev9-0ubuntu1 in Karmic, "dbus-send --session --print-reply --dest=org.desktopcouch.CouchDB / org.desktopcouch.CouchDB.getPort" returns the following output:

Error org.freedesktop.DBus.Python.IOError: Traceback (most recent call last):
  File "/usr/lib/pymodules/python2.6/dbus/service.py", line 702, in _message_cb
    retval = candidate_method(self, *args, **keywords)
  File "/usr/lib/desktopcouch/desktopcouch-service", line 58, in getPort
    return int(desktopcouch.find_port())
  File "/usr/lib/python2.6/dist-packages/desktopcouch/__init__.py", line 87, in find_port
    with open(FILE_LOG, 'r') as log_file:

Hi Murat, thanks for filing this bug report and helping us make desktopcouch better!

Looks like there is a bug in the port finder. Assigning to you, Stuart, feel free to kick to someone else, or back to me, just don't want it to get lost.

[Stuart Langridge (sil)]

I *think* this is because desktopcouch is not starting up couchdb correctly, which will be fixed by the larger get-the-port changes. Murat, thanks for the bug report; would you be prepared to try a package from a PPA to see if it fixes your problem? (once this package exists :))

[Murat Gunes (mgunes)]

Stuart, surely; let me know when it's up.

[Chad Miller (cmiller)]

This is surely caused by two things: desktopcouch-service does not start couchdb directly (normal), and if couchdb has never been started, then the log file does not exist. Since the get_port code does not expect a log file never to exist, the first call (and all subsequent) to get_port fails.

When we continue using the log-searching code, then we must catch OSErrors and treat them as no port found.

For now, reverting to the /proc searching code.
