From 83b59c557cc0e759231e9b4f386aa445218b3b43 Mon Sep 17 00:00:00 2001 From: Boog900 <54e72d8a-345f-4599-bd90-c6b9bc7d0ec5@aleeas.com> Date: Tue, 30 Jan 2024 16:09:54 +0000 Subject: [PATCH] net: use epee_encoding instead of monero-epee-bin-serde This gives us more control than what serde provides. This PR also moves to use `Bytes` where possible to allow zero-copy parsing of network messages. --- Cargo.lock | 48 +++--- consensus/Cargo.toml | 4 +- consensus/src/rpc/connection.rs | 121 +++++++++----- net/epee-encoding/Cargo.toml | 1 + net/epee-encoding/src/container_as_blob.rs | 99 ++++++++++++ net/epee-encoding/src/lib.rs | 16 +- net/epee-encoding/src/macros.rs | 43 +++-- net/epee-encoding/src/value.rs | 42 ++++- net/epee-encoding/tests/alt_name.rs | 2 +- net/epee-encoding/tests/duplicate_key.rs | 4 +- net/epee-encoding/tests/epee_default.rs | 20 +-- net/epee-encoding/tests/flattend.rs | 8 +- net/epee-encoding/tests/options.rs | 8 +- net/epee-encoding/tests/p2p.rs | 6 +- net/epee-encoding/tests/rpc.rs | 14 +- net/epee-encoding/tests/seq.rs | 8 +- net/epee-encoding/tests/stack_overflow.rs | 2 +- net/fixed-bytes/src/lib.rs | 19 +++ net/levin/src/codec.rs | 25 +-- net/levin/src/lib.rs | 13 +- net/monero-wire/Cargo.toml | 7 +- net/monero-wire/src/lib.rs | 1 - net/monero-wire/src/network_address.rs | 20 ++- .../src/network_address/serde_helper.rs | 74 ++++++--- net/monero-wire/src/p2p.rs | 39 ++--- net/monero-wire/src/p2p/admin.rs | 76 ++++++--- net/monero-wire/src/p2p/common.rs | 141 +++++++++++------ net/monero-wire/src/p2p/protocol.rs | 147 +++++++++++------- net/monero-wire/src/serde_helpers.rs | 35 ----- p2p/monero-p2p/tests/handshake.rs | 4 +- 30 files changed, 709 insertions(+), 338 deletions(-) create mode 100644 net/epee-encoding/src/container_as_blob.rs delete mode 100644 net/monero-wire/src/serde_helpers.rs diff --git a/Cargo.lock b/Cargo.lock index aa315d8b..c434aed8 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -438,10 +438,10 @@ dependencies = [ "curve25519-dalek", "dalek-ff-group", "dirs", + "epee-encoding", "futures", "hex", "monero-consensus", - "monero-epee-bin-serde", "monero-serai", "monero-wire", "multiexp", @@ -604,6 +604,7 @@ dependencies = [ "fixed-bytes", "hex", "paste", + "ref-cast", "sealed", "thiserror", ] @@ -1142,16 +1143,6 @@ dependencies = [ "tracing", ] -[[package]] -name = "monero-epee-bin-serde" -version = "1.0.1" -source = "git+https://github.com/monero-rs/monero-epee-bin-serde.git?rev=fae7a23#fae7a23f8e57f19553c341c0878b4f0fa5a6994d" -dependencies = [ - "byteorder", - "serde", - "serde_bytes", -] - [[package]] name = "monero-generators" version = "0.4.0" @@ -1232,11 +1223,11 @@ dependencies = [ name = "monero-wire" version = "0.1.0" dependencies = [ + "bytes", + "epee-encoding", + "fixed-bytes", "hex", "levin-cuprate", - "monero-epee-bin-serde", - "serde", - "serde_bytes", "thiserror", ] @@ -1587,6 +1578,26 @@ dependencies = [ "thiserror", ] +[[package]] +name = "ref-cast" +version = "1.0.22" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "c4846d4c50d1721b1a3bef8af76924eef20d5e723647333798c1b519b3a9473f" +dependencies = [ + "ref-cast-impl", +] + +[[package]] +name = "ref-cast-impl" +version = "1.0.22" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "5fddb4f8d99b0a2ebafc65a87a69a7b9875e4b1ae1f00db265d300ef7f28bccc" +dependencies = [ + "proc-macro2", + "quote", + "syn 2.0.48", +] + [[package]] name = "regex-syntax" version = "0.8.2" @@ -1770,15 +1781,6 @@ dependencies = [ "serde_derive", ] -[[package]] -name = "serde_bytes" -version = "0.11.14" -source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "8b8497c313fd43ab992087548117643f6fcd935cbf36f176ffda0aacf9591734" -dependencies = [ - "serde", -] - [[package]] name = "serde_derive" version = "1.0.195" diff --git a/consensus/Cargo.toml b/consensus/Cargo.toml index 8619a33e..393c4dfd 100644 --- a/consensus/Cargo.toml +++ b/consensus/Cargo.toml @@ -21,7 +21,7 @@ binaries = [ "dep:tracing-subscriber", "dep:serde_json", "dep:serde", - "dep:monero-epee-bin-serde", + "dep:epee-encoding", "dep:monero-wire", "dep:borsh", "dep:dirs", @@ -51,7 +51,7 @@ hex = "0.4" # used in binaries monero-wire = {path="../net/monero-wire", optional = true} -monero-epee-bin-serde = { workspace = true , optional = true} +epee-encoding = { path="../net/epee-encoding" , optional = true} serde_json = {version = "1", optional = true} serde = {version = "1", optional = true, features = ["derive"]} tracing-subscriber = {version = "0.3", optional = true} diff --git a/consensus/src/rpc/connection.rs b/consensus/src/rpc/connection.rs index 7fd8707c..780d160e 100644 --- a/consensus/src/rpc/connection.rs +++ b/consensus/src/rpc/connection.rs @@ -1,3 +1,4 @@ +use std::ops::Deref;
