The rack gem returns PATH_INFO as an ASCII-8BIT encoded string but it
was being converted to US-ASCII by the match? method because it was
calling Rack::Utils.escape_path. To prevent incompatibile encoding
warnings use ASCII-8BIT strings for the root path and let Ruby handle
any filename encoding conversion.
Fixes#32294, Closes#32314.
Set `config.static_index` to serve a static directory index file not
named `index`. For example, to serve `main.html` instead of `index.html`
for directory requests, set `config.static_index` to `"main"`.
When using compute_source_path to determine the full path of an
asset, if our source begins with '/', we don't want to include
the directory. Examples are illustrative:
> compute_source_path("foo", "stylesheets", "css")
=> "/Users/steve/src/my_app/public/stylesheets/foo.css"
> compute_source_path("/foo", "stylesheets", "css")
=> "/Users/steve/src/my_app/public/foo.css"
Before this patch, the second example would return the same as the
first.
Fixes#5680.
Windows doesn't allow `\ / : * ? " < > |` in filenames so create
the fixture files at runtime and ignore the incompatible ones when
running on Windows.
RFC 3986[1] allows sub-delim characters in path segments unencoded,
however Rack::File requires them to be encoded so we use URI's
unescape method to leave them alone and then escape them again.
Also since the path gets passed to Dir[] we need to escape any glob
characters in the path.
