Upload exactly the shared files needed and give precedence to global files over local ones #1340
Conversation
This file contains hidden or bidirectional Unicode text that may be interpreted or compiled differently than what appears below. To review, open the file in an editor that reveals hidden Unicode characters.

This avoids false positives for the essential files. Previously, docs.rs would copy any files with a resource suffix as an essential file, even if it couldn't be shared between crates (such as search-index.js).
This avoids copying shared files for crates other than the empty
library. This
a) Allows removing `copy_doc_dir`, which allows crates to add their own custom CSS (with `--theme` or otherwise), and
b) Avoids unnecessary disk IO.
Here are the files generated for a build of regex 1.4.1:
```
cratesfyi=# select path from files where path like '%regex/1.4.1%' and path not like '%regex/1.4.1/%/%';

Note in particular that search-index.js and crates.js are included, but
not shared files like `storage.js` or `rustdoc.css`.
This avoids broken docs for crates build with an old version of rustdoc that didn't respect the shared static root.
