From: Eric Huss Date: Mon, 17 Sep 2018 02:41:57 +0000 (-0700) Subject: --all-targets fixes X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=3a1cad6f2851401542951bc78f6ed78dcb978edd;p=cargo.git --all-targets fixes - Fix: `cargo test --all-targets` was running lib tests three times. - `--all-targets` help strings were wrong or misleading. - Minor cleanup to add `Proposal` type to maybe make the code more readable. --- diff --git a/src/bin/cargo/commands/bench.rs b/src/bin/cargo/commands/bench.rs index ea12a4575..b688e36a5 100644 --- a/src/bin/cargo/commands/bench.rs +++ b/src/bin/cargo/commands/bench.rs @@ -26,7 +26,7 @@ pub fn cli() -> App { "Benchmark all tests", "Benchmark only the specified bench target", "Benchmark all benches", - "Benchmark all targets (default)", + "Benchmark all targets", ) .arg(opt("no-run", "Compile, but don't run benchmarks")) .arg_package_spec( @@ -78,7 +78,6 @@ pub fn exec(config: &mut Config, args: &ArgMatches) -> CliResult { let ops = TestOptions { no_run: args.is_present("no-run"), no_fail_fast: args.is_present("no-fail-fast"), - only_doc: false, compile_opts, }; diff --git a/src/bin/cargo/commands/build.rs b/src/bin/cargo/commands/build.rs index f1c8b256b..9a3e27213 100644 --- a/src/bin/cargo/commands/build.rs +++ b/src/bin/cargo/commands/build.rs @@ -22,7 +22,7 @@ pub fn cli() -> App { "Build all tests", "Build only the specified bench target", "Build all benches", - "Build all targets (lib and bin targets by default)", + "Build all targets", ) .arg_release("Build artifacts in release mode, with optimizations") .arg_features() diff --git a/src/bin/cargo/commands/check.rs b/src/bin/cargo/commands/check.rs index 72cebfda8..c9bbac1e7 100644 --- a/src/bin/cargo/commands/check.rs +++ b/src/bin/cargo/commands/check.rs @@ -21,7 +21,7 @@ pub fn cli() -> App { "Check all tests", "Check only the specified bench target", "Check all benches", - "Check all targets (lib and bin targets by default)", + "Check all targets", ) .arg_release("Check artifacts in release mode, with optimizations") .arg(opt("profile", "Profile to build the selected target for").value_name("PROFILE")) diff --git a/src/bin/cargo/commands/fix.rs b/src/bin/cargo/commands/fix.rs index f88e52794..b98968b54 100644 --- a/src/bin/cargo/commands/fix.rs +++ b/src/bin/cargo/commands/fix.rs @@ -21,7 +21,7 @@ pub fn cli() -> App { "Fix all tests", "Fix only the specified bench target", "Fix all benches", - "Fix all targets (lib and bin targets by default)", + "Fix all targets (default)", ) .arg_release("Fix artifacts in release mode, with optimizations") .arg(opt("profile", "Profile to build the selected target for").value_name("PROFILE")) diff --git a/src/bin/cargo/commands/rustc.rs b/src/bin/cargo/commands/rustc.rs index a5ca4deff..dd2f1aa2c 100644 --- a/src/bin/cargo/commands/rustc.rs +++ b/src/bin/cargo/commands/rustc.rs @@ -19,7 +19,7 @@ pub fn cli() -> App { "Build all tests", "Build only the specified bench target", "Build all benches", - "Build all targets (lib and bin targets by default)", + "Build all targets", ) .arg_release("Build artifacts in release mode, with optimizations") .arg(opt("profile", "Profile to build the selected target for").value_name("PROFILE")) diff --git a/src/bin/cargo/commands/rustdoc.rs b/src/bin/cargo/commands/rustdoc.rs index 9dda84f2e..8593bd2d0 100644 --- a/src/bin/cargo/commands/rustdoc.rs +++ b/src/bin/cargo/commands/rustdoc.rs @@ -23,7 +23,7 @@ pub fn cli() -> App { "Build all tests", "Build only the specified bench target", "Build all benches", - "Build all targets (default)", + "Build all targets", ) .arg_release("Build artifacts in release mode, with optimizations") .arg_features() diff --git a/src/bin/cargo/commands/test.rs b/src/bin/cargo/commands/test.rs index d6df9484d..0e9b577b5 100644 --- a/src/bin/cargo/commands/test.rs +++ b/src/bin/cargo/commands/test.rs @@ -27,7 +27,7 @@ pub fn cli() -> App { "Test all tests", "Test only the specified bench target", "Test all benches", - "Test all targets (default)", + "Test all targets", ) .arg(opt("doc", "Test only this library's documentation")) .arg(opt("no-run", "Compile, but don't run tests")) @@ -116,7 +116,6 @@ pub fn exec(config: &mut Config, args: &ArgMatches) -> CliResult { let ops = ops::TestOptions { no_run: args.is_present("no-run"), no_fail_fast: args.is_present("no-fail-fast"), - only_doc: doc, compile_opts, }; diff --git a/src/cargo/ops/cargo_compile.rs b/src/cargo/ops/cargo_compile.rs index 58d177104..0c353d9bc 100644 --- a/src/cargo/ops/cargo_compile.rs +++ b/src/cargo/ops/cargo_compile.rs @@ -444,6 +444,22 @@ impl CompileFilter { } } +/// A proposed target. +/// +/// Proposed targets are later filtered into actual Units based on whether or +/// not the target requires its features to be present. +#[derive(Debug)] +struct Proposal<'a> { + pkg: &'a Package, + target: &'a Target, + /// Indicates whether or not all required features *must* be present.
