Using Evolution With Chandler Hub and Chandler Server

Evolution is a personal information manager for GNOME/Linux.

Evolution supports subscribing to CalDAV calendars with its CalDAV plugin.

As of November 2007 there are known issues with Evolution integration. As a result, subscribing to Chandler Server with Evolution is unsupported. If you would like to help debug these problems, you may use the below instructions to point Evolution at Chandler Server.

Some issues seen during testing:

• When creating events, cosmo returns a weak ETag, which means the ETag is prefixed with "W/". When updating the event, Evolution includes the "W/" in the If-Match header, which is incorrect. The server interprets the etag as different and returns a modified response. The workaround is to reload the calendar, which should result in the correct etag sent the next update.
• Evolution's handling of recurring events is really buggy. For instance, if you add a modification to a recurring series, Evolution just includes the modification in the PUT, which is wrong. Also, Evolution doesn't seem to display event modifications correctly.

Subscribing to a Calendar

1. Select menu item "File", "New", "Calendar", or alternately:
   1. Click on the Calendars button
   2. Right-click in the sidebar and select New Calendar
2. For Type select "CalDAV" from the drop-down list
3. For Name enter something meaningful - this name is only seen on the Evolution side
4. Obtain the CalDAV URL for the desired collection, probably by using the Chandler Server web UI collection details dialog.
5. For URL enter the URL of the calendar with the caldav scheme rather than http (example caldav://osaf.us/cosmo/home/bear/collection)
6. Select the "Use SSL" button if you want access to the server to be encrypted and if the server supports it (osaf.us does).
7. For Username enter your Cosmo username
8. Click on the OK button
