Local rustdoc search doesn't work with --no-deps

[Boddlnagg]

I'm having an issue that is similar to rust-lang/docs.rs#316, but it's about local docs.

I'm using cargo doc --no-deps --open, and on the opened page the search does not work. It shows "Loading search results..." and doesn't complete, just like in the link above.

The JS console says: TypeError: paths is undefined (main.js:95:15458), and in the JS debugger I see the following: It's trying to access rawSearchIndex['byteorder'].p, but rawSearchIndex['byteorder'] does not have p. It looks like the following:

rawSearchIndex['byteorder']: {…}
doc: "This crate provides convenience methods for encoding and decoding numbers in either [big-endian or little-endian order]."
items: (265) […]
paths: (5) […]
<prototype>: {…}

However, for my own crate it works correctly:

rawSearchIndex['climeta']: {…}
doc: ""
i: (2184) […]
p: (143) […]
<prototype>: {…}

Actually I guess there should be nothing about byteorder at all in the index, because I built the docs with --no-deps, and alas, when building without --no-deps, the search works!

Now, I tried to build again with --no-deps, and it still works. Apparently it was trying to load some old index file that had an outdated format ...

It's great when a problem gets solved while writing the issue report 😆, but I think this issue might still serve a purpose, so I'll open it anyway, if only for others to find it. And maybe rustdoc should try harder to not load outdated index files.

And now I noticed: When I build with --no-deps after having built without --no-deps, the other crates are still shown in the docs and found via the index, but I want to see only my own crate ... do I have to delete the target/doc directory?

Yes, when generating docs, rustdoc look at the target directory and changes a few things depending on what it finds. To go back on your original issue, I think it'll fail again if you remove the folder and regenerate with --no-deps. I'll assign myself on it.

triage: seems fixed

[GuillaumeGomez]

Please don't close issues if there is no regression test.

[lolbinarycat]

is there a label for "fixed, but has no regression test"?

[GuillaumeGomez]

Not that I know of.
