Hi,
This discussion is more debian related, but it might help trunk as well.
This is a list of steps and fixes I made for the packaging of trunk with regards
to the base I have for 4.1.1 which in turn builds on the debian 3.2 package.
First attempt to build trunk as a package failed in dependency on pycalendar [1].
(upgrading pycalendar to r214 took 3 attempts as it was not clear what branch to use)
With the dependencies installed the server died with [2]
twext.enterprise.dal.parseschema.ViolatedExpectation: Expected Token.Keyword got None:
This was fixed with patch [3] (simple whitespace addition).
Now the same error as before appeared.
I also got some information from Peter Mogensen (off list) that detailed that
he saw the same problem but only when the debian package was installed.
(eg, a pure SVN checkout worked, but failed when the debian package was present)
He reported it was totally dependent on the presens
/usr/share/pyshared/twisted/plugins/caldav.py
I did several tests, but at the end I "fixed it" by removing the RuntimeError
exception. [4] The logging in the patch did not work, it can be left out.
I probably do not use the log as it is meant to be used.
I added a printout in the twext/backport/internet/tcp.py
and it got printed, so I assume that the patching went fine.
Lastly psutil in Debian is version 0.5.1 and version 0.6.0 is needed to
have virtual_memory method. [5]
I have not yet backported the change to 4.1.1 but do not expect problems, I just
wanted to check if the change (removing the exception) is reasonable ?
If ok, I will prepare the 4.1.1 debian package and put it online for testing.
/Fred
