Modernize backends dependencies #22
Description
Description
Most of the DAV code relies on Sabre components which aren't very modern. Proper types when implementing interfaces and extending classes would be nicer.
Affected components
- CalDAV and CardDAV backends
To do
- vObject Modernize code sabre-io/vobject#562 PHP 7.4 types sabre-io/vobject#586
- DAV Annotate parameter type/return type sabre-io/dav#1368
- Sabre/http
Would be nice to have:
- Sabre/uri
- Sabre/xml
- Sabre/event
