When the `--extern-html-root-url` flag is given one of your dependencies, rustdoc use that URL for those docs. Keep in mind that if those docs exist in the output directory, those local docs will still override this flag. +The names in this flag are first matched against the names given in the `--extern name=` flags, +which allows selecting between multiple crates with the same name (e.g. multiple versions of +the same crate). For transitive dependencies that haven't been loaded via an `--extern` flag, matching +falls backs to using crate names only, without ability to distinguish between multiple crates with +the same name. + ## `-Z force-unstable-if-unmarked` Using this flag looks like this: diff --git a/src/librustdoc/doctest.rs b/src/librustdoc/doctest.rs index a32c2f7fb18c5..0bef091468f2b 100644 --- a/src/librustdoc/doctest.rs +++ b/src/librustdoc/doctest.rs @@ -11,7 +11,8 @@ use std::path::{Path, PathBuf}; use std::process::{self, Command, Stdio}; use std::sync::atomic::{AtomicUsize, Ordering}; use std::sync::{Arc, Mutex}; -use std::{panic, str}; +use std::time::{Duration, Instant}; +use std::{fmt, panic, str}; pub(crate) use make::{BuildDocTestBuilder, DocTestBuilder}; pub(crate) use markdown::test as test_markdown; @@ -36,6 +37,50 @@ use crate::config::{Options as RustdocOptions, OutputFormat}; use crate::html::markdown::{ErrorCodes, Ignore, LangString, MdRelLine}; use crate::lint::init_lints; +/// Type used to display times (compilation and total) information for merged doctests. +struct MergedDoctestTimes { + total_time: Instant, + /// Total time spent compiling all merged doctests. + compilation_time: Duration, + /// This field is used to keep track of how many merged doctests we (tried to) compile. + added_compilation_times: usize, +} + +impl MergedDoctestTimes { + fn new() -> Self { + Self { + total_time: Instant::now(), + compilation_time: Duration::default(), + added_compilation_times: 0, + } + } + + fn add_compilation_time(&mut self, duration: Duration) { + self.compilation_time += duration; + self.added_compilation_times += 1; + } + + fn display_times(&self) { + // If no merged doctest was compiled, then there is nothing to display since the numbers + // displayed by `libtest` for standalone tests are already accurate (they include both + // compilation and runtime). + if self.added_compilation_times > 0 { + println!("{self}"); + } + } +} + +impl fmt::Display for MergedDoctestTimes { + fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result { + write!( + f, + "all doctests ran in {:.2}s; merged doctests compilation took {:.2}s", + self.total_time.elapsed().as_secs_f64(), + self.compilation_time.as_secs_f64(), + ) + } +} + /// Options that apply to all doctests in a crate or Markdown file (for `rustdoc foo.md`). #[derive(Clone)] pub(crate) struct GlobalTestOptions { @@ -295,6 +340,7 @@ pub(crate) fn run_tests( let mut nb_errors = 0; let mut ran_edition_tests = 0; + let mut times = MergedDoctestTimes::new(); let target_str = rustdoc_options.target.to_string(); for (MergeableTestKey { edition, global_crate_attrs_hash }, mut doctests) in mergeable_tests { @@ -314,13 +360,15 @@ pub(crate) fn run_tests( for (doctest, scraped_test) in &doctests { tests_runner.add_test(doctest, scraped_test, &target_str); } - if let Ok(success) = tests_runner.run_merged_tests( + let (duration, ret) = tests_runner.run_merged_tests( rustdoc_test_options, edition, &opts, &test_args, rustdoc_options, - ) { + ); + times.add_compilation_time(duration); + if let Ok(success) = ret { ran_edition_tests += 1; if !success { nb_errors += 1; @@ -354,11 +402,13 @@ pub(crate) fn run_tests( test::test_main_with_exit_callback(&test_args, standalone_tests, None, || { // We ensure temp dir destructor is called. std::mem::drop(temp_dir.take()); + times.display_times(); }); } if nb_errors != 0 { // We ensure temp dir destructor is called. std::mem::drop(temp_dir); + times.display_times(); // libtest::ERROR_EXIT_CODE is not public but it's the same value. std::process::exit(101); } @@ -496,16 +546,19 @@ impl RunnableDocTest { /// /// This is the function that calculates the compiler command line, invokes the compiler, then /// invokes the test or tests in a separate executable (if applicable). +/// +/// Returns a tuple containing the `Duration` of the compilation and the `Result` of the test. fn run_test( doctest: RunnableDocTest, rustdoc_options: &RustdocOptions, supports_color: bool, report_unused_externs: impl Fn(UnusedExterns), -) -> Result<(), TestFailure> { +) -> (Duration, Result<(), TestFailure>) { let langstr = &doctest.langstr; // Make sure we emit well-formed executable names for our target. let rust_out = add_exe_suffix("rust_out".to_owned(), &rustdoc_options.target); let output_file = doctest.test_opts.outdir.path().join(rust_out); + let instant = Instant::now(); // Common arguments used for compiling the doctest runner. // On merged doctests, the compiler is invoked twice: once for the test code itself, @@ -589,7 +642,7 @@ fn run_test( if std::fs::write(&input_file, &doctest.full_test_code).is_err() { // If we cannot write this file for any reason, we leave.
