lorenzo	c1c2507148	p2p: fix DiscReason encoding/decoding (#30855) ... This fixes an issue where the disconnect message was not wrapped in a list. The specification requires it to be a list like any other message. In order to remain compatible with legacy geth versions, we now accept both encodings when parsing a disconnect message. --------- Co-authored-by: Felix Lange <fjl@twurst.com>	2 months ago
Martin HS	9045b79bc2	metrics, cmd/geth: change init-process of metrics (#30814) ... This PR modifies how the metrics library handles `Enabled`: previously, the package `init` decided whether to serve real metrics or just dummy-types. This has several drawbacks: - During pkg init, we need to determine whether metrics are enabled or not. So we first hacked in a check if certain geth-specific commandline-flags were enabled. Then we added a similar check for geth-env-vars. Then we almost added a very elaborate check for toml-config-file, plus toml parsing. - Using "real" types and dummy types interchangeably means that everything is hidden behind interfaces. This has a performance penalty, and also it just adds a lot of code. This PR removes the interface stuff, uses concrete types, and allows for the setting of Enabled to happen later. It is still assumed that `metrics.Enable()` is invoked early on. The somewhat 'heavy' operations, such as ticking meters and exp-decay, now checks the enable-flag to prevent resource leak. The change may be large, but it's mostly pretty trivial, and from the last time I gutted the metrics, I ensured that we have fairly good test coverage. --------- Co-authored-by: Felix Lange <fjl@twurst.com>	3 months ago

Felix Lange	7194c847b6	p2p/rlpx: reduce allocation and syscalls (#22899) ... This change significantly improves the performance of RLPx message reads and writes. In the previous implementation, reading and writing of message frames performed multiple reads and writes on the underlying network connection, and allocated a new []byte buffer for every read. In the new implementation, reads and writes re-use buffers, and perform much fewer system calls on the underlying connection. This doubles the theoretically achievable throughput on a single connection, as shown by the benchmark result: name old speed new speed delta Throughput-8 70.3MB/s ± 0% 155.4MB/s ± 0% +121.11% (p=0.000 n=9+8) The change also removes support for the legacy, pre-EIP-8 handshake encoding. As of May 2021, no actively maintained client sends this format.	4 years ago
rene	129cf075e9	p2p: move rlpx into separate package (#21464) ... This change moves the RLPx protocol implementation into a separate package, p2p/rlpx. The new package can be used to establish RLPx connections for protocol testing purposes. Co-authored-by: Felix Lange <fjl@twurst.com>	4 years ago
