From: Elias Rohrer Date: Mon, 10 Oct 2022 18:47:18 +0000 (-0400) Subject: Add `futures` CI check X-Git-Tag: v0.0.112~16^2 X-Git-Url: http://git.bitcoin.ninja/index.cgi?a=commitdiff_plain;h=0038a3f7dea705823939909c60bbd3826362bc1f;p=rust-lightning Add `futures` CI check This adds testing of the `futures` feature to CI. In order to avoid introducing a dependency on `std`, we switch to using the `futures-util` crate directly enabling only a subset of features. To this end, we also switch to using the `select_biased!` macro, which is equivalent to `select!` except that it doesn't choose ready futures pseudo-randomly at runtime. --- diff --git a/.github/workflows/build.yml b/.github/workflows/build.yml index 799d22a64..171c57fcb 100644 --- a/.github/workflows/build.yml +++ b/.github/workflows/build.yml @@ -12,7 +12,7 @@ jobs: beta, # 1.41.1 is MSRV for Rust-Lightning, lightning-invoice, and lightning-persister 1.41.1, - # 1.45.2 is MSRV for lightning-net-tokio, lightning-block-sync, and coverage generation + # 1.45.2 is MSRV for lightning-net-tokio, lightning-block-sync, lightning-background-processor, and coverage generation 1.45.2, # 1.47.0 will be the MSRV for no-std builds using hashbrown once core2 is updated 1.47.0] @@ -20,34 +20,43 @@ jobs: - toolchain: stable build-net-tokio: true build-no-std: true + build-futures: true - toolchain: stable platform: macos-latest build-net-tokio: true build-no-std: true + build-futures: true - toolchain: beta platform: macos-latest build-net-tokio: true build-no-std: true + build-futures: true - toolchain: stable platform: windows-latest build-net-tokio: true build-no-std: true + build-futures: true - toolchain: beta platform: windows-latest build-net-tokio: true build-no-std: true + build-futures: true - toolchain: beta build-net-tokio: true build-no-std: true + build-futures: true - toolchain: 1.41.1 build-no-std: false test-log-variants: true + build-futures: false - toolchain: 1.45.2 build-net-old-tokio: true build-net-tokio: true build-no-std: false + build-futures: true coverage: true - toolchain: 1.47.0 + build-futures: true build-no-std: true runs-on: ${{ matrix.platform }} steps: @@ -109,7 +118,7 @@ jobs: - name: Test on Rust ${{ matrix.toolchain }} with net-tokio and full code-linking for coverage generation if: matrix.coverage run: RUSTFLAGS="-C link-dead-code" cargo test --verbose --color always - - name: Test on no-std bullds Rust ${{ matrix.toolchain }} + - name: Test no-std builds on Rust ${{ matrix.toolchain }} if: "matrix.build-no-std && !matrix.coverage" shell: bash # Default on Winblows is powershell run: | @@ -140,15 +149,26 @@ jobs: run: | cd lightning RUSTFLAGS="-C link-dead-code" cargo test --verbose --color always --no-default-features --features no-std - cd .. + - name: Test futures builds on Rust ${{ matrix.toolchain }} + if: "matrix.build-futures && !matrix.coverage" + shell: bash # Default on Winblows is powershell + run: | + cd lightning-background-processor + cargo test --verbose --color always --no-default-features --features futures + - name: Test futures builds on Rust ${{ matrix.toolchain }} and full code-linking for coverage generation + if: "matrix.build-futures && matrix.coverage" + shell: bash # Default on Winblows is powershell + run: | + cd lightning-background-processor + RUSTFLAGS="-C link-dead-code" cargo test --verbose --color always --no-default-features --features futures - name: Test on Rust ${{ matrix.toolchain }} if: "!
