This change makes it so, instead of mixing string distance with
type unification, function signature search works by
mapping names to IDs at the start, reporting to the user any
cases where it had to make corrections, and then matches with
IDs when going through the items.
This only changes function searches. Name searches are left alone,
and corrections are only done when there's a single item in the
search query.
This makes sense, since the search index has the information in it,
and it's more useful for function signature searches since a
function signature search's item type is, by definition, some type
of function (there's more than one, but not very many).
All static files used by rustdoc are now stored in static.files/ and
include a hash of their contents. They no longer include the contents of
the --resource-suffix flag. This clarifies caching semantics. Anything
in static.files can use Cache-Control: immutable because any updates
will show up as a new URL.
Invocation-specific files like crates-NN.js, search-index-NN.js,
and sidebar-items-NN.js still get the resource suffix.
The --disable-minification flag is removed because it would vary the
output of static files based on invocation flags. Instead, for
rustdoc development purposes it's preferable to symlink static files
to a non-minified copy for quick iteration.
Previously, search.js relied on the DOM and the `window` object. It can now be
loaded in the absence of the DOM, for instance by Node. The same is true of
search-index.js.
This allows removing a lot of code from src/tools/rustdoc-js/tester.js that
tried to parse search.js and extract specific functions that were needed for
testing.
Fix a crash when searching for an alias contained in the currently selected filter crate.
Also remove alias search results for crates that should be filtered out.
The test suite needed to be fixed to actually take into account the crate filtering and check that there are no results when none are expected.
Fixes rustdoc-js tests by teaching tester.js how to handle single-line js comments.
Also, added speculative support for template strings, and warnings for future debuggers.
