From: Matt Corallo Date: Fri, 24 Apr 2020 18:22:26 +0000 (-0400) Subject: Run with mutagen on travis. X-Git-Url: http://git.bitcoin.ninja/index.cgi?a=commitdiff_plain;h=c8b51228d6c7012659aa4b4a37591dc27222937c;p=rust-lightning Run with mutagen on travis. Sadly our test coverage isn't very good and I had to hunt for functions to mutate where we fail tests on every mutation mutagen creates, but committing the framework is a start. --- diff --git a/.github/workflows/build.yml b/.github/workflows/build.yml index cd9b9f635..50a3b7c04 100644 --- a/.github/workflows/build.yml +++ b/.github/workflows/build.yml @@ -7,7 +7,7 @@ jobs: strategy: matrix: toolchain: [ stable, - beta, + nightly, # 1.22.0 is MSRV for rust-lightning in general: 1.22.0, # 1.34.2 is Debian stable @@ -17,8 +17,9 @@ jobs: include: - toolchain: stable build-net-tokio: true - - toolchain: beta + - toolchain: nightly build-net-tokio: true + run-mutagen: true - toolchain: 1.39.0 build-net-tokio: true coverage: true @@ -44,6 +45,16 @@ jobs: - name: Test on Rust ${{ matrix.toolchain }} if: "! matrix.build-net-tokio" run: RUSTFLAGS="-C link-dead-code" cargo test --verbose --color always -p lightning + - name: Run mutagen tests on ${{ matrix.toolchain }} + if: matrix.run-mutagen + # Run mutagen on nightly with TheBlueMatt's fork which exits with non-0 status + # if any mutations resulted in anything except test failures to prevent regressions. + run: | + rm -rf mutagen && git clone https://github.com/TheBlueMatt/mutagen + cargo install --force --path mutagen/mutagen-runner + cd lightning + ~/.cargo/bin/cargo-mutagen --features mutation_testing + # Generate code cov information on Rust 1.39.0 - name: Install deps for kcov if: matrix.coverage run: | diff --git a/.travis.yml b/.travis.yml index 0c36806c6..dcb3a11bf 100644 --- a/.travis.yml +++ b/.travis.yml @@ -1,7 +1,7 @@ language: rust rust: - stable - - beta + - nightly # 1.22.0 is MSRV for rust-lightning in general: - 1.22.0 # 1.34.2 is Debian stable @@ -15,7 +15,7 @@ before_install: - sudo apt-get install -y binutils-dev libunwind8-dev libcurl4-openssl-dev libelf-dev libdw-dev cmake gcc binutils-dev libiberty-dev script: - # Support lightning-net-tokio only on Rust stable, beta, and 1.39.0 + # Support lightning-net-tokio only on Rust stable, nightly, and 1.39.0 - if [ "$(rustup show | grep default | grep '1.39.0')" != "" ]; then export BUILD_NET_TOKIO=1; fi - if [ "$(rustup show | grep default | grep '1\.')" == "" ]; then export BUILD_NET_TOKIO=1; fi # Build the appropriate workspace(s) @@ -27,6 +27,13 @@ script: - if [ "$BUILD_NET_TOKIO" != "1" ]; then RUSTFLAGS="-C link-dead-code" cargo test --verbose -p lightning; fi # Run lightning workspace fuzz tests on Rust stable - if [ "$(rustup show | grep default | grep stable)" != "" ]; then cd fuzz && cargo test --verbose && ./ci-fuzz.sh; fi + # Run mutagen on nightly with TheBlueMatt's fork which exits with non-0 status + # if any mutations resulted in anything except test failures to prevent regressions. + - if [ "$(rustup show | grep default | grep nightly)" != "" ]; then + rm -rf mutagen && git clone https://github.com/TheBlueMatt/mutagen && + cargo install --force --path mutagen/mutagen-runner && + cd lightning && + ~/.cargo/bin/cargo-mutagen --features mutation_testing; fi # Generate code cov information on Rust 1.39.0 - if [ "$(rustup show | grep default | grep 1.39.0)" != "" ]; then wget https://github.com/SimonKagstrom/kcov/archive/master.tar.gz && diff --git a/lightning/Cargo.toml b/lightning/Cargo.toml index f89b54818..3be6b7d33 100644 --- a/lightning/Cargo.toml +++ b/lightning/Cargo.toml @@ -11,7 +11,6 @@ Still missing tons of error-handling.
