- This is untested and unused, string ownership is very much subject to change
- Ports the minimally necessary parts of complete.rs as well
- This should fix an infinite loop in `create_directory` in `path.rs`, the first
`wstat` loop only breaks if it fails with an error that's different from
EAGAIN
- wildcard_match is now closer to the original that is linked in a comment, as
pointer-arithmetic translates very poorly. The act of calling wildcard
patterns wc or wildcard is kinda confusing when wc elsewhere is widechar.
Most of it is duplicated, hence untested.
Functions like mbrtowc are not exposed by the libc crate, so declare them
ourselves.
Since we don't know the definition of C macros, add two big hacks to make
this work:
1. Replace MB_LEN_MAX and mbstate_t with values (resp types) that should
be large enough for any implementation.
2. Detect the definition of MB_CUR_MAX in the build script. This requires
more changes for each new libc. We could also use this approach for 1.
Additionally, this commit brings a small behavior change to
read_unquoted_escape(): we cannot decode surrogate code points like \UDE01
into a Rust char, so use � (\UFFFD, replacement character) instead.
Previously, we added such code points to a wcstring; looks like they were
ignored when printed.
