From 77962aa79df5671e206635cc6980e4b1ac969bf9 Mon Sep 17 00:00:00 2001 From: Zach Prezkuta Date: Sat, 2 Jun 2012 16:11:31 -0600 Subject: [PATCH] Fix bugs in the retraction code 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?)
