This commit adds basic syncing capabilities with peers if they are both
online.
It updates the work done on MVDS, but I decided to create the code in
status-go instead, since it's very tight to the application (similarly
the code that was the inspiration for mvds, bramble, is all tight
together at the database level).
I reused parts of the protobufs.
The flow is:
1) An OFFER message is sent periodically with a bunch of message-ids and
group-ids.
2) Anyone can REQUEST some of those messages if not present in their
database.
3) The peer will then send over those messages.
It's disabled by default, but I am planning to add a way to set up the
flags.
This functionality is needed in case the user wants to send a transaction and
signs it using the signature provided by the keycard (or any other compatible way).
This commit enables mailserver cycle logic by default and make a few
changes:
1) Nodes are graylisted instead of being blacklisted for a set amount of
time. The reason is that if we blacklist, any cut in connectivity
might result in long delays before reconnecting, especially on spotty
connections.
2) Fixes an issue on the devp2p server, whereby the node would not
connect to one of the static nodes since all the connection slots
where filled. The fix is a bit inelegant, it always connects to
static nodes, ignoring maxpeers, but it's tricky to get it to work
since the code is clearly not written to select a specific node.
3) Adds support to pinned mailservers
4) Add retries to mailservers requests. It uses a closure for now, I
think we should eventually have a channel etc, but I'd leave that for
later.
This fix puts an end to a saga that essentially start during the
Status Prague Meetup at the end of October 2018. At the time we were
experiencing massive issues with `Connecting...` spinners in the app in the
venue we rented. We were pulling our hairs out what to do and we could not
find the cause of the issue at the time.
Three months later I deployed the following change:
https://github.com/status-im/infra-eth-cluster/commit/63a13eed
Which used `iptables` to map the `443` port onto our `30504` Status node port
using `PREROUTING` chain and `REDIRECT` jump in order to fix issues people
have been complaining about when using WiFi networks in various venues:
https://github.com/status-im/status-react/issues/6351
Our thinking when trying to resolve the reported issue assumed that some
networks might block outgoing connections on non-standard ports other than
the usual `80`(HTTP)/`443`(HTTPS) which would disrupt Status connectivity.
While this fix could have indeed helped a few edge cases, what it really
did was cause the Status node to stop seeing actual public IPs of the clients.
But __pure accident__ this change caused the code we inherited from
`go-ethereum` implementation of DevP2P protocol to stop throttling new
incoming connections, because the IP as which they appeared was a
`172.16.0.0/12` network address of the Docker bridge.
The `go-ethereum` code used the `!netutil.IsLAN(remoteIP)` check to
avoid throttling connections from local addresses, which included the
local Docker bridge address:
https://github.com/status-im/status-go/blob/82680830/vendor/github.com/ethereum/go-ethereum/p2p/netutil/net.go#L36
The fix intended to target a small number of networks with fortified
firewall configuration accidentally resolved our issues with
`Connecting...` prompts that our application showed us en masse during
our Prauge Meetup. Part of the reason for that is that venues like that
normally give out local IP addresses and use NAT to translate them onto
the only public IP address they possess.
Since out application is supposed to be usable from within networks
behind NAT like airport WiFi networks for example, it makes no sense to
keep the inbound connection throttle time implemented in `go-ethereum`.
I'm leaving `inboundThrottleTime` in because it's used to calculate
value for `dialHistoryExpiration` in:
`vendor/github.com/ethereum/go-ethereum/p2p/dial.go`
I believe reducing that value one we deploy this change should also
increase the speed with which the Status application is able to reconnect
to a node that was temporarily unavailable, instead waiting the 5*30 seconds.
