MySQL stores TIMESTAMP columns as UTC, but with a local time interface. (SRSLY?!) DATETIME columns are always bare and assumed to be local time, but we keep only UTC in them.
Forcing the session time_zone to UTC means we won't have to worry as much about what we're sending/receiving in there.
Also will let us remove the hack in master commit a7abb2323e for session tweaks
Had to tweak statusnet.ini to remove the DB_DATAOBJECT_MYSQLTIMESTAMP bitfield constant on session.modified; while it sounds like a useful and legit setting, it actually just means that DB_DataObject silently fails to pass through any attempts to explicitly set the value. As a result, MySQL does its default behavior which is to insert the current *LOCAL* time, which is useless.
This was leading to early GC west of GMT, or late GC east of it. Early GC could at worst destroy all live sessions (whoever's session *triggered* GC is fine, as the session then gets saved right back.)
Previously, if someone you subscribe to repeats a notice by someone you've blocked, you got the message and had to just roll your eyes.
Now blocks are checked against both the current notice's posting profile, and the poster of the original if it's a repeat.
It seems to have actually been saving correctly, but the update of the colors on the form success page wasn't working properly.
When a design object is pulled out of the database, the numeric fields are read in as strings, so black comes back as "0".
But, when we populate the new object and then stick it live, we've populated it with actual integers; with memcache on these might live for a while in the cache...
The fallback code in Design::toWebColor() did a check ($color == null) which would be false for the string "0", but counts as true for the *integer* 0.
Thus, the display code would initially interpret the correctly-saved black color as "use default".
Changing the check to === against null and "" empty string avoids the false positive on integers, and lets us see our nice black text immediately after save.
* adds Right::CREATEGROUP
* logic in Profile::hasRight() checks for silencing
* NewgroupAction checks for the permission before letting you see or process the form in the UI
* User_group::register() logic does a low-level check on the specified initial group admin, and rejects creation if that user doesn't have the right; guaranteeing that API methods etc will also have this restriction applied sensibly.
