Hi, I am the Debian maintainer for calendarserver. For calendarserver 6.2, I have the new binaries built, including a new package for twext. But when I run it, I get the error: # caldavd -L Traceback (most recent call last): 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 652, in run config.parseOptions() File "/usr/lib/python2.7/dist-packages/twisted/application/app.py", line 619, in parseOptions usage.Options.parseOptions(self, options) File "/usr/lib/python2.7/dist-packages/twisted/python/usage.py", line 262, in parseOptions for (cmd, short, parser, doc) in self.subCommands: File "/usr/lib/python2.7/dist-packages/twisted/application/app.py", line 636, in subCommands for plug in sorted(plugins, key=attrgetter('tapname')): File "/usr/lib/python2.7/dist-packages/twisted/plugins/caldav.py", line 29, in getProperty return getattr(reflect.namedClass(self.serviceMakerClass), propname) File "/usr/lib/python2.7/dist-packages/twisted/python/reflect.py", line 168, in namedObject module = namedModule('.'.join(classSplit[:-1])) File "/usr/lib/python2.7/dist-packages/twisted/python/reflect.py", line 154, in namedModule topLevel = __import__(name) File "/usr/lib/python2.7/dist-packages/txdav/dps/server.py", line 21, in <module> from calendarserver.tap.util import getDBPool, storeFromConfigWithDPSServer File "/usr/lib/python2.7/dist-packages/calendarserver/tap/util.py", line 33, in <module> from calendarserver.provision.root import RootResource File "/usr/lib/python2.7/dist-packages/calendarserver/provision/root.py", line 37, in <module> from twistedcaldav.directory.principal import DirectoryPrincipalResource File "/usr/lib/python2.7/dist-packages/twistedcaldav/directory/principal.py", line 56, in <module> from twistedcaldav.resource import CalendarPrincipalCollectionResource, CalendarPrincipalResource File "/usr/lib/python2.7/dist-packages/twistedcaldav/resource.py", line 77, in <module> from calendarserver.push.notifier import getPubSubAPSConfiguration File "/usr/lib/python2.7/dist-packages/calendarserver/push/notifier.py", line 29, in <module> from txdav.common.datastore.sql_tables import schema File "/usr/lib/python2.7/dist-packages/txdav/common/datastore/sql_tables.py", line 78, in <module> schema = _populateSchema() File "/usr/lib/python2.7/dist-packages/txdav/common/datastore/sql_tables.py", line 64, in _populateSchema return SchemaSyntax(schemaFromPath(pathObj)) File "/usr/lib/python2.7/dist-packages/twext/enterprise/dal/parseschema.py", line 105, in schemaFromPath addSQLToSchema(schema, schemaData) File "/usr/lib/python2.7/dist-packages/twext/enterprise/dal/parseschema.py", line 152, in addSQLToSchema t = tableFromCreateStatement(schema, stmt) File "/usr/lib/python2.7/dist-packages/twext/enterprise/dal/parseschema.py", line 89, in tableFromCreateStatement cp.parse() File "/usr/lib/python2.7/dist-packages/twext/enterprise/dal/parseschema.py", line 335, in parse while self.nextColumn(): File "/usr/lib/python2.7/dist-packages/twext/enterprise/dal/parseschema.py", line 347, in nextColumn return self.parseColumn(maybeIdent.get_name()) File "/usr/lib/python2.7/dist-packages/twext/enterprise/dal/parseschema.py", line 515, in parseColumn theDefault.tokens[-1], cls=Parenthesis File "/usr/lib/python2.7/dist-packages/twext/enterprise/dal/parseschema.py", line 710, in expectSingle cls, "%s:%r" % (nextval.__class__.__name__, nextval) twext.enterprise.dal.parseschema.ViolatedExpectation: Expected <class 'sqlparse.sql.Parenthesis'> got Comment:<Comment '-- imp...' at 0x7fe4f014c490> Attaching the caldavd.plist file that I am using. The postgres database is created and pre-populated with the schema. Could you provide any pointers on why this is occurring? On a side note, if I run using the normal way i.e. ./bin/run -n, then it starts properly. So, not sure what is the issue here. Thanks, Rahul.
