Summary0002574: No colors selectable if ressource ID contains space character

After migrating some data to SOGo using the CalDAV interface, we experienced an issue with some resources for which we cannot select a resource color. All these Calendars have in common that they include whitespace in their name. We have also been able to reproduce the problem using the restore feature in sogo-tool.

Steps To Reproduce
  • Edit backup containing calendar

  • Change the ressource ID to include whitespace, for example

    "/Users/user42/Calendar/DEAD BEEF" = {

  • Import this folder using sogo-tool: sogo-tool restore -f 'Calendar/DEAD BEEF' backup.1 user42

  • A new calendar will be created, not having a color set ("transparent"), also no background for appointments

  • Try to change the color of the calendar: Will not be stored

Additional Information

If another calendar with ID DEAD exists, its color will be changed and also used for calendar with ID DEAD BEEF (SOGo seems to cut everything behind that space).

TagsNo tags attached.

How did you end up having a space in the calendar ID? If it's by messing around the data, you're shooting yourself in the foot.

We got the space by creating a calendar via davfs.
We migrated complete calendars from Zimbra to SOGo with a script.
The original calendar had the space in its name.

We created these calendars using DAV, by creating directories (which might be not valid regarding the standard, but worked fine nonetheless). It seems this is a way to sink invalid data into SOGo and those invalid UIDs might be better subject to verification before being accepted (and breaking later in other places).

We might better create calendars using the "official" way be sending an MKCALENDAR command using curl in future.

Anyway, in my reading UIDs containing spices are valid as defined by RFC 5545.

uid        = "UID" uidparam ":" text CRLF

text       = *(TSAFE-CHAR / ":" / DQUOTE / ESCAPED-CHAR)
TSAFE-CHAR = WSP / %x21 / %x23-2B / %x2D-39 / %x3C-5B / %x5D-7E / NON-US-ASCII

WSP            =  SP / HTAB
SP             =  %x20

It might be well possible that I read over some limitations, but the grammar definitely includes the space character.
