Péter Szilágyi	d4fd06c3dc	all: blidly swap out glog to our log15, logs need rework	8 years ago
Felix Lange	a2b4abd89a	rpc: send nil on subscription Err channel when Client is closed ... This change makes client subscriptions compatible with the new Subscription semantics introduced in the previous commit.	8 years ago
Felix Lange	e32925397b	rpc: add context argument to EthSubscribe ... It's inconsistent not to pass it and most callers will work with contexts anyway.	8 years ago
Felix Lange	f5f042ffdc	rpc: ensure client doesn't block for slow subscribers ... I initially made the client block if the 100-element buffer was exceeded. It turns out that this is inconvenient for simple uses of the client which subscribe and perform calls on the same goroutine, e.g. client, _ := rpc.Dial(...) ch := make(chan int) // note: no buffer sub, _ := client.EthSubscribe(ch, "something") for event := range ch { client.Call(...) } This innocent looking code will lock up if the server suddenly decides to send 2000 notifications. In this case, the client's main loop won't accept the call because it is trying to deliver a notification to ch. The issue is kind of hard to explain in the docs and few people will actually read them. Buffering is the simple option and works with close to no overhead for subscribers that always listen.	8 years ago
Felix Lange	464660651d	rpc: don't exceed context deadline while waiting for send lock	8 years ago
Felix Lange	91b7690428	rpc: add new client, use it everywhere ... The new client implementation supports concurrent requests, subscriptions and replaces the various ad hoc RPC clients throughout go-ethereum.	8 years ago
