Upgrade fails when specific properties containing UTF-8 characters are processed
by Kristoffer 22 Dec '15

22 Dec '15

Hi, I am trying to upgrade from calendar server version 4.2 to version 7.0 by starting version 7.0 of the server connected to a database originating from version 4.2. The upgrade process seems to start correctly, but after a while the process is aborted. Some properties in the resource_property table contains UTF-8 characters and that seems to abort the upgrade process and make the server shut down. The following lines are an example from the error log when the problem happens: 2015-12-14 13:14:03+0000 [-] [calendarserver.tap.util#error] Step failure Traceback (most recent call last): File

Error messages from CalendarServer-7.0 when using external PostgreSQL database
by Kristoffer Møllerhøj 02 Dec '15

Hi, I observed a problem when running the development build of CalendarServer-7.0 using an external PostgreSQL database. Errors like the following shows up: 2015-11-11 14:25:59+0100 [-] [caldav-0] [-] [twext.enterprise.jobs.jobitem#error] JobItem: 72, WorkItem: 72 failed: [Failure instance: Traceback: <type 'exceptions.TypeError'>: Unicode value for key 'id' not allowed: u'/CalDAV/localhost/10000000-0000-0000-0000-000000000001/calendar/' When running the same setup with internal PostgreSQL database everything seems to work fine. Have anybody else observed this problem? I also created a bugreport: http://trac.calendarserver.org/ticket/923 Best regards, Kristoffer Møllerhøj.
