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 [1] File "/usr/lib/python2.7/dist-packages/twistedcaldav/__init__.py", line 70, in <module> PyCalendarProperty.registerDefaultValue("X-CALENDARSERVER-PRIVATE-COMMENT", PyCalendarValue.VALUETYPE_TEXT) AttributeError: type object 'PyCalendarProperty' has no attribute 'registerDefaultValue' [2] File "/usr/bin/twistd", line 14, in <module> run() File "/usr/lib/python2.7/dist-packages/twisted/scripts/twistd.py", line 27, in run app.run(runApp, ServerOptions) File "/usr/lib/python2.7/dist-packages/twisted/application/app.py", line 647, in run config.parseOptions() File "/usr/lib/python2.7/dist-packages/twisted/application/app.py", line 614, in parseOptions usage.Options.parseOptions(self, options) File "/usr/lib/python2.7/dist-packages/twisted/python/usage.py", line 261, in parseOptions for (cmd, short, parser, doc) in self.subCommands: File "/usr/lib/python2.7/dist-packages/twisted/application/app.py", line 631, in subCommands for plug in sorted(plugins, key=attrgetter('tapname')): File "/usr/lib/python2.7/dist-packages/twisted/plugins/caldav.py", line 31, in getProperty return getattr(reflect.namedClass(self.serviceMakerClass), propname) File "/usr/lib/python2.7/dist-packages/twisted/python/reflect.py", line 351, in namedObject module = namedModule('.'.join(classSplit[:-1])) File "/usr/lib/python2.7/dist-packages/twisted/python/reflect.py", line 339, in namedModule topLevel = __import__(name) File "/usr/lib/python2.7/dist-packages/twistedcaldav/scheduling/imip/mailgateway.py", line 26, in <module> from calendarserver.tap.util import getRootResource, directoryFromConfig File "/usr/lib/python2.7/dist-packages/calendarserver/tap/util.py", line 51, in <module> from twistedcaldav.directory import calendaruserproxy File "/usr/lib/python2.7/dist-packages/twistedcaldav/directory/calendaruserproxy.py", line 46, in <module> from twistedcaldav.directory.principal import formatLink File "/usr/lib/python2.7/dist-packages/twistedcaldav/directory/principal.py", line 70, in <module> from twistedcaldav.resource import CalendarPrincipalCollectionResource, CalendarPrincipalResource File "/usr/lib/python2.7/dist-packages/twistedcaldav/resource.py", line 82, in <module> from twistedcaldav.sharing import SharedCollectionMixin, SharedHomeMixin File "/usr/lib/python2.7/dist-packages/twistedcaldav/sharing.py", line 33, in <module> from txdav.common.datastore.sql_tables import _BIND_MODE_OWN, \ File "/usr/lib/python2.7/dist-packages/txdav/common/datastore/sql_tables.py", line 48, in <module> schema = _populateSchema() File "/usr/lib/python2.7/dist-packages/txdav/common/datastore/sql_tables.py", line 44, in _populateSchema return SchemaSyntax(schemaFromPath(pathObj)) File "/usr/lib/python2.7/dist-packages/twext/enterprise/dal/parseschema.py", line 92, in schemaFromPath addSQLToSchema(schema, schemaData) File "/usr/lib/python2.7/dist-packages/twext/enterprise/dal/parseschema.py", line 121, in addSQLToSchema t = tableFromCreateStatement(schema, stmt) File "/usr/lib/python2.7/dist-packages/twext/enterprise/dal/parseschema.py", line 76, in tableFromCreateStatement cp.parse() File "/usr/lib/python2.7/dist-packages/twext/enterprise/dal/parseschema.py", line 228, in parse while self.nextColumn(): File "/usr/lib/python2.7/dist-packages/twext/enterprise/dal/parseschema.py", line 242, in nextColumn return self.parseConstraint(maybeIdent) File "/usr/lib/python2.7/dist-packages/twext/enterprise/dal/parseschema.py", line 314, in parseConstraint expect(self, ttype=Keyword, value='KEY') File "/usr/lib/python2.7/dist-packages/twext/enterprise/dal/parseschema.py", line 516, in expect return expectSingle(nextval, **kw) File "/usr/lib/python2.7/dist-packages/twext/enterprise/dal/parseschema.py", line 496, in expectSingle raise ViolatedExpectation(ttype, '%s:%r' % (nextval.ttype, nextval)) twext.enterprise.dal.parseschema.ViolatedExpectation: Expected Token.Keyword got None:<Function 'key(HO...' at 0x2340758> [3] Index: txdav/common/datastore/sql_schema/current.sql =================================================================== --- txdav/common/datastore/sql_schema/current.sql (revision 10029) +++ txdav/common/datastore/sql_schema/current.sql (working copy) @@ -35,7 +35,7 @@ PORT integer not null, TIME timestamp not null default timezone('UTC', CURRENT_TIMESTAMP), - primary key(HOSTNAME, PORT) + primary key (HOSTNAME, PORT) ); [4] --- a/twext/patches.py +++ b/twext/patches.py @@ -59,6 +59,9 @@ (i.e., all of C{twext/backport}) should be removed upon upgrading our minimum required Twisted version.
