scrape-examples does not fingerprint correctly #10876
Description
Problem
Running cargo doc twice with -Zrustdoc-scrape-examples, the second run should not do anything. However, it is running rustdoc again to scrape the examples.
Steps
Changing the scrape_examples_basic test to run cargo doc one more time should not execute anything. However, it is redoing the scrape.
diff --git a/tests/testsuite/doc.rs b/tests/testsuite/doc.rs index 00971c2cd..760cb47ce 100644 --- a/tests/testsuite/doc.rs +++ b/tests/testsuite/doc.rs @@ -2395,6 +2395,11 @@ fn scrape_examples_basic() { // Ensure that the reverse-dependency has its sources generated assert!(p.build_dir().join("doc/src/ex/ex.rs.html").exists()); + + p.cargo("doc -Zunstable-options -Z rustdoc-scrape-examples=all") + .masquerade_as_nightly_cargo(&["rustdoc-scrape-examples"]) + .with_stderr("[FINISHED] ..") + .run(); } #[cargo_test]Possible Solution(s)
I have not looked, but I suspect the fingerprinting of Docscrape units isn't working.
