Diaspora "relayable_retraction" is now supported by Friendica.
The following should now work:
Friendica top-level post:
Diaspora comment deleted, disappears in Friendica
Friendica comment deleted, disappears in Diaspora
Diaspora like retracted, disappears in Friendica
Friendica like retracted, disappears in Diaspora
Diaspora top-level post:
Same
There are still exceptions, however. First, Friendica and Diaspora
seem to frequently reject comments with an "invalid signature" error.
This can probably be fixed.
Also, some comments/likes/retractions seem to just disappear on the
Diaspora side. In the Diaspora log these seem to be accompanied by a
"not a valid object" error, often preceeded by a "received a comment
but no corresponding post" error. These seem to be purely internal,
since sometimes it works for some Diaspora contacts but not others.
Currently, the following seems to be the functional status:
For a Diaspora top-level post:
Friendica comments show up AND delete
Diaspora comments show up AND delete for top-level owner
Diaspora comments show up for non-owner
Diaspora comments sometimes don't delete for non-owner
-> Appears to be Diaspora's fault, as a "not a valid object" error shows up in the log
Friendica likes show up, but can't unlike (Friendica doesn't even message Diaspora)
Diaspora likes show up
Diaspora non-owner can't unlike
-> Same as comments, seems to be Diaspora's fault
For a Friendica top-level post:
Friendica comments show up AND delete
Diaspora comments show up AND delete
Friendica likes don't show up in Diaspora sometimes
Friendica doesn't even message Diaspora for unlikes (sometimes?)
Diaspora likes and unlikes work
