4da9e8a617 Support more than one grub list 
- Connecting to / redirects to /<random string>
- Connecting to /:list-name connects users to the list
  :list-name. Changes are synced only with this list.
- A cookie saves the last list visited, so future / visits go to last list

20c408e491 Add two-way sync assertion and simplify down buffer 
- Down buffer is no longer a sliding buffer of size one but just
 a buffer of size 1. It cannot be pushed into if it is full.

cd7397ef40 CSP: Re-specification of sync algorithm with Datomic in mind 
- This specification ignores the actual diffing/patching itself and
  concerns itself only with the current database, server, and client t
  or database time.

838e6497d4 Correct fetching of database values 
The existing way did not work for local database for some reason. The
	existing approach tried to fetch all attributes for a given
	entity. We now specifically fetch the attributes we want for an
	entity, which is better anyway.

619f21e4d8 CSP: Introduce a one element sliding buffer when DB changes are saved

b3b8011719 CSP: Fix issue over which events can be communicated when 2015-08-19 20:50:08 +03:00
Nicholas Kariniemi
0cebe1f5ab Fix deadlock in previous implementation 
by only allowing new inputs if the previous one has been "acked".

I.e. if you send one diff, you don't process any more diffs until you
	receive a diff back. This is something specified in the Neil Frasier
	paper and also something needed to prevent deadlock.
