class IOldNevowResource(components.Interface):

i think it has something to do with the versions of zope and twisted. not sure what the right combination is.

OpenXCAP works with the latest version of Twisted Web2. You can either get it from the twisted SVN on twistedmatrix.com, or if you're using Debian Linux, make sure you have the latest version of python-twisted-web2 from the public repository.

Replying to nmattiello:

Yes, the latest version in debian for web2 is 0.2.0+svn20070403-1 (and for twisted-core is 2.5.0-2).

ok, i was finally able to check out from twisted's svn after some firewall issues and got the web2 from there. that seemed to work, but now i get:

File "/root/openxcap/xcap/dbutil.py", line 65, in connectionForURI

raise AssertionError("Database scheme '%s' is not supported." % scheme)

NameError: global name 'scheme' is not defined

scratch that last comment. i downloaded the newer openxcap and now get:

File "/usr/lib/python2.4/site-packages/xcap/interfaces/backend/database.py", line 33, in ?

configuration = ConfigFile('config.ini')

NameError: name 'ConfigFile' is not defined

im assuming i dont have the file that defines ConfigFile. where would it be?

OpenXCAP 0.9.3 depends on python-application 1.0.9 so you must update that too. If you're using Debian, you can apt-get install python-application (the package is in the public repository), otherwise you can take it from here: http://download.dns-hosting.info/OpenXCAP/

[nmattiello]

ok, i installed the newer python-application correctly this time. im back to the unsupported database schema error. i looked at database.py and theres a couple things ive noticed:

I get the error "global name 'scheme' not defined" because of this code: def connectionForURI(uri):

"""Return a Twisted adbapi connection pool for a given database URI.""" schema, user, password, host, port, path, args = parseURI(uri) try:

module = db_modules[schema]

except:

raise AssertionError("Database scheme '%s' is not supported." % scheme)

In the "raise" statement, i think instead of 'scheme' you want 'schema'.

additionally, the only schemas i see support for are:

db_modules = {"mysql": "MySQLdb"}

but on the main page it says you support postgres as well, which is what i am trying to use.

[admin]

I've fixed the "schema" typo in the trunk, but indeed postgres is not yet supported (it's on our TODO list), shouldn't be difficult though and if you want to contribute you're more that welcomed.
