Fix bug where `rustdoc-js` tester would not pick the right `search.js` file if there is more than one #145359

GuillaumeGomez · 2025-08-13T15:28:05Z

It happened to me quite a few times recently when I worked on the search index:

I make a change in search.js
I run rustdoc-js tests
nothing changes

So my solution was to simply remove the folder, but it's really suboptimal. With this PR, it now picks the most recently modified file.

LGTM, besides two tiny edge cases that probably don't matter:

if another search-related js file is added, the regex may be too permissive (can just be fixed whenever it comes up, and hopefully won't be too much of a pain to debug)
if somehow no file matches, this will give an index out of bounds error (but it should also give a stack trace pointing right to the code that needs updating)

Also considered if this could hit editor temporary files, but since the regex checks prefix and suffix, it never should.

src/tools/rustdoc-js/tester.js

@@ -452,7 +467,7 @@ function loadSearchJS(doc_folder, resource_suffix) {
    };

    const staticFiles = path.join(doc_folder, "static.files");
-    const searchJs = fs.readdirSync(staticFiles).find(f => f.match(/search.*\.js$/));
+    const searchJs = mostRecentMatch(staticFiles, /search.*\.js$/);


Suggested change

const searchJs = mostRecentMatch(staticFiles, /search.*\.js$/);

const searchJs = mostRecentMatch(staticFiles, /search-[0-9a-f]{8}.*\.js$/);

What do you think about making the regex a bit stricter in case we add another search-related js module at some point? The .* is still needed because of --resource-suffix, but maybe it would be a bit more reliable?

Good idea, applied it.

I added a check for the number of matching files and it emits an exception if it's 0.
