@@ -118,11 +118,18 @@ Features:
- support "const" properties as flag
- add API to clone sd_bus_message objects
- SD_BUS_COMMENT() macro for inclusion in vtables, syntax inspired by gdbus
+ - systemd-bus-proxyd needs to synthesize NameLost/NameAcquired
- kdbus: matches against source or destination pids for an "strace -p"-like feel. Problem: The PID info needs to be available in userspace too...
- kdbus: we need a way to figure out whether there's currently an activator for a name that is already activated
- longer term:
* priority queues
* priority inheritance
+ - move to siphash for bloom filter
+ - dbus spec updates:
+ - kdbus mapping
+ - NameLost/NameAcquired obsolete
+ - GVariant
+ - "const" properties
* sd-event
- allow multiple signal handlers per signal?
