From 0e7ddc020ff9db07137df3b487fb8b00bad8160c Mon Sep 17 00:00:00 2001 From: Lars Wirzenius Date: Tue, 14 Jul 2026 08:46:34 +0300 Subject: [PATCH] feat: add a sub-crate with things needed by an adapter implement in Rust Move radicle_ci_broker::msg::* to radicle_ci_adapter::*. This is meant to make building adapters in Rust to build much faster, as they only need to build new radicle_ci_adapter crate, not the whole of radicle_ci_broker. --- Cargo.lock | 37 +- Cargo.toml | 8 +- adapterlib/Cargo.toml | 37 ++ adapterlib/examples/adapter.rs | 30 ++ adapterlib/src/lib.rs | 893 +++++++++++++++++++++++++++++++++ src/adapter.rs | 9 +- src/bin/cibtoolcmd/message.rs | 7 +- src/msg.rs | 855 +------------------------------ src/pages.rs | 1 + trigger.json | 1 + 10 files changed, 1041 insertions(+), 837 deletions(-) create mode 100644 adapterlib/Cargo.toml create mode 100644 adapterlib/examples/adapter.rs create mode 100644 adapterlib/src/lib.rs create mode 100644 trigger.json diff --git a/Cargo.lock b/Cargo.lock index bf17ffe5..0b27c05a 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -2126,9 +2126,39 @@ dependencies = [ "unicode-normalization", ] +[[package]] +name = "radicle-ci-adapter" +version = "0.1.0" +dependencies = [ + "clap", + "duration-str", + "git-ref-format-core", + "html-page", + "libc", + "nonempty 0.12.0", + "radicle", + "radicle-crypto", + "radicle-job", + "radicle-surf", + "regex", + "rss", + "serde", + "serde_json", + "serde_norway", + "sqlite", + "subplotlib", + "tempfile", + "thiserror 2.0.18", + "time", + "tracing", + "tracing-subscriber", + "url", + "uuid", +] + [[package]] name = "radicle-ci-broker" -version = "0.30.0" +version = "0.30.1" dependencies = [ "clap", "culpa", @@ -2140,6 +2170,7 @@ dependencies = [ "qcheck", "qcheck-macros", "radicle", + "radicle-ci-adapter", "radicle-crypto", "radicle-job", "radicle-surf", @@ -2781,9 +2812,9 @@ dependencies = [ [[package]] name = "spin" -version = "0.9.8" +version = "0.9.9" source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "6980e8d7511241f8acf4aebddbb1ff938df5eebe98691418c4468d0b72a96a67" +checksum = "3763264f6b73151db08c50ff20d7d8a0b8796e021cdea7ceedad07b80155fa0e" [[package]] name = "spki" diff --git a/Cargo.toml b/Cargo.toml index 02fa1176..2553ed18 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -1,6 +1,11 @@ +[workspace] +members = [ + "adapterlib" +] + [package] name = "radicle-ci-broker" -version = "0.30.0" +version = "0.30.1" edition = "2024" rust-version = "1.90" authors = ["Lars Wirzenius "] @@ -18,6 +23,7 @@ html-page = "0.5.0" libc = "0.2.183" nonempty = "0.12.0" radicle = { version = "0.24.0", features = ["default", "test"] } +radicle-ci-adapter = { version = "0.1.0", path = "adapterlib" } radicle-crypto = "0.17.0" radicle-job = "0.6.0" radicle-surf = { version = "0.28.0", default-features = false, features = ["serde"] } diff --git a/adapterlib/Cargo.toml b/adapterlib/Cargo.toml new file mode 100644 index 00000000..fb5dfa99 --- /dev/null +++ b/adapterlib/Cargo.toml @@ -0,0 +1,37 @@ +[package] +name = "radicle-ci-adapter" +version = "0.1.0" +edition = "2024" +rust-version = "1.90" +authors = ["Lars Wirzenius "] +description = "implement Radicle CI adapters in Rust" +license = "MIT OR Apache-2.0" +homepage = "https://radicle.dev" +repository = "https://radicle.network/nodes/radicle.liw.fi/rad:zwTxygwuz5LDGBq255RA2CbNGrz8" +categories = ["development-tools::build-utils"] + +[dependencies] +clap = { version = "4.6.0", features = ["derive", "wrap_help"] } +duration-str = "0.21.0" +git-ref-format-core = "0.6.0" +html-page = "0.5.0" +libc = "0.2.183" +nonempty = "0.12.0" +radicle = { version = "0.24.0", features = ["default", "test"] } +radicle-crypto = "0.17.0" +radicle-job = "0.6.0" +radicle-surf = { version = "0.28.0", default-features = false, features = ["serde"] } +regex = "1.12.3" +rss = "2.0.12" +serde = { version = "1.0.228", features = ["derive"] } +serde_json = "1.0.149" +serde_norway = "0.9.42" +sqlite = "0.37.0" +subplotlib = "0.14.0" +tempfile = { version = "3.27.0" } +thiserror = "2.0.18" +time = { version = "0.3.47", features = ["formatting", "macros"] } +tracing = { version = "0.1.44", features = ["max_level_trace", "release_max_level_trace", "valuable"] } +tracing-subscriber = { version = "0.3.23", features = ["env-filter", "fmt", "json", "valuable"] } +url = "2.5.8" +uuid = { version = "1.22.0", features = ["v4"] } diff --git a/adapterlib/examples/adapter.rs b/adapterlib/examples/adapter.rs new file mode 100644 index 00000000..65d6856b --- /dev/null +++ b/adapterlib/examples/adapter.rs @@ -0,0 +1,30 @@ +//!
