By tracking which events are reachable +from each state set we can finish early if every pending event is reachable from +every state set. + +This can work well for state sets that have a small auth chain difference, but +can be very inefficient for larger differences. However, this algorithm is still +used if we don't have a chain cover index for the room (e.g. because we're in +the process of indexing it). + +## Chain Cover Index + +Synapse computes auth chain differences by pre-computing a "chain cover" index +for the auth chain in a room, allowing efficient reachability queries like "is +event A in the auth chain of event B". This is done by assigning every event a +*chain ID* and *sequence number* (e.g. `(5,3)`), and having a map of *links* +between chains (e.g. `(5,3) -> (2,4)`) such that A is reachable by B (i.e. `A` +is in the auth chain of `B`) if and only if either: + +1. A and B have the same chain ID and `A`'s sequence number is less than `B`'s + sequence number; or +2. there is a link `L` between `B`'s chain ID and `A`'s chain ID such that + `L.start_seq_no` <= `B.seq_no` and `A.seq_no` <= `L.end_seq_no`. + +There are actually two potential implementations, one where we store links from +each chain to every other reachable chain (the transitive closure of the links +graph), and one where we remove redundant links (the transitive reduction of the +links graph) e.g. if we have chains `C3 -> C2 -> C1` then the link `C3 -> C1` +would not be stored. Synapse uses the former implementations so that it doesn't +need to recurse to test reachability between chains. + +### Example + +An example auth graph would look like the following, where chains have been +formed based on type/state_key and are denoted by colour and are labelled with +`(chain ID, sequence number)`. Links are denoted by the arrows (links in grey +are those that would be remove in the second implementation described above). + + + +Note that we don't include all links between events and their auth events, as +most of those links would be redundant. For example, all events point to the +create event, but each chain only needs the one link from it's base to the +create event. + +## Using the Index + +This index can be used to calculate the auth chain difference of the state sets +by looking at the chain ID and sequence numbers reachable from each state set: + +1. For every state set lookup the chain ID/sequence numbers of each state event +2. Use the index to find all chains and the maximum sequence number reachable + from each state set. +3. The auth chain difference is then all events in each chain that have sequence + numbers between the maximum sequence number reachable from *any* state set and + the minimum reachable by *all* state sets (if any). + +Note that steps 2 is effectively calculating the auth chain for each state set +(in terms of chain IDs and sequence numbers), and step 3 is calculating the +difference between the union and intersection of the auth chains. + +### Worked Example + +For example, given the above graph, we can calculate the difference between +state sets consisting of: + +1. `S1`: Alice's invite `(4,1)` and Bob's second join `(2,2)`; and +2. `S2`: Alice's second join `(4,3)` and Bob's first join `(2,1)`. + +Using the index we see that the following auth chains are reachable from each +state set: + +1. `S1`: `(1,1)`, `(2,2)`, `(3,1)` & `(4,1)` +2. `S2`: `(1,1)`, `(2,1)`, `(3,2)` & `(4,3)` + +And so, for each the ranges that are in the auth chain difference: +1. Chain 1: None, (since everything can reach the create event). +2. Chain 2: The range `(1, 2]` (i.e. just `2`), as `1` is reachable by all state + sets and the maximum reachable is `2` (corresponding to Bob's second join). +3. Chain 3: Similarly the range `(1, 2]` (corresponding to the second power + level). +4. Chain 4: The range `(1, 3]` (corresponding to both of Alice's joins). + +So the final result is: Bob's second join `(2,2)`, the second power level +`(3,2)` and both of Alice's joins `(4,2)` & `(4,3)`. diff --git a/docs/openid.md b/docs/openid.md index da391f74aa..b86ae89768 100644 --- a/docs/openid.md +++ b/docs/openid.md @@ -42,11 +42,10 @@ as follows: * For other installation mechanisms, see the documentation provided by the maintainer. -To enable the OpenID integration, you should then add an `oidc_config` section -to your configuration file (or uncomment the `enabled: true` line in the -existing section).
