From 335e6006c51d0b64c3ffb89f298af7fe40822b4a Mon Sep 17 00:00:00 2001 From: Brandon Black Date: Tue, 20 Oct 2026 02:33:23 -0700 Subject: [PATCH 01/14] layout: compile library tests against the normal rlib Move each library's tests into one suite target so cargo test links the dev rlib, and split initial block download into rbitcoin-ibd so RPC and Electrum do not build it.

The gate is still unrounded `LH*100 >= LF*89`. +- **Library tests compile against the normal rlib.** Each library package except `rbitcoin-bench` has one `tests/suite` target (`[lib] test = false` and `doctest = false`, including `rbitcoin-ibd`), so `cargo test` no longer rebuilds the crate under `--cfg test`. Bench still runs with `cargo test -p rbitcoin-bench --lib`. `test-hooks` is gone. Hooks a test arms stay `cfg(debug_assertions)`. A debug node still uses the 8 s outbound connect timeout and still aborts when an io_uring drain leaves SQEs. Initial block download is `rbitcoin-ibd`, and RPC, Electrum, Esplora, and SV2 do not depend on it. The consensus suite is the package's default `corpus` feature (the Core script assembler). Product crates depend on consensus with `default-features = false`, so a node build leaves that assembler out. `rbitcoin-test`'s default scenarios are one `suite` binary; `overlay` stays feature-gated. `NODE_COMPACT_FILTERS` is advertised per peer hub, so one process can run more than one node. +- **Production line-coverage floor is 91%.** Suite tests link the normal rlib, so `#[cfg(test)]` lines are no longer in the LCOV denominator. The measured ratio on this layout is 91.26% (93410/102361). The gate is still unrounded `LH*100 >= LF*91`. diff --git a/crates/rbitcoin-ibd/Cargo.toml b/crates/rbitcoin-ibd/Cargo.toml index 9380f5b13c..841424c52e 100644 --- a/crates/rbitcoin-ibd/Cargo.toml +++ b/crates/rbitcoin-ibd/Cargo.toml @@ -10,6 +10,7 @@ description = "Multi-peer initial block download and confirm pipeline" [lib] test = false +doctest = false [features] mutants = [] diff --git a/docs/quality.md b/docs/quality.md index f99283747f..a09aac7c7c 100644 --- a/docs/quality.md +++ b/docs/quality.md @@ -68,7 +68,7 @@ at an explicit rank with **Q-63+**. | **—** | Large process-resident body, pin, or archive caches (FIFO, LRU, or sticky residency).
