Hello,
I got a report that SyncEvolution does not handle CATEGORIES correctly
in ical 2.0 events when multiple categories are specified. It turned out
that Evolution or more likely, libical, import/export such events with
the comma separator escaped like this:
CATEGORIES:Anniversary\,Holiday
RFC 2445 specifies CATEGORIES with a normal comma as separator and gives
this example:
CATEGORIES:APPOINTMENT,EDUCATION
When importing such an event, Evolution stores it with two different
category properties and then only uses the later one in the GUI:
CATEGORIES:APPOINTMENT
CATEGORIES:EDUCATION
At first glance there doesn't seem to be an open bug related to this; it
still happens with Evolution 2.10. I will open a bug and investigate
further, but let me bring up some points here first:
* I suppose right now Evolution continues to use its own libical.
Are there plans to synchronize with upstream (whathever that is
at the moment)?
Evolution-2.10 uses the libical from the stable branch. Evolution-2.12
would use the libical from svn HEAD. Evolution does not own a separate
libical.
* Any bug fix for this should be backwards compatible and treat \,
just like a normal comma because all existing .ics files will
continue to contain \, and I would like to add a hack to
SyncEvolution which converts between \, and , to work around the
issue in existing Evolution versions.
The bug is in libical and any fix made there would be done so that its
backward compatible.
