This commit adds a `--remove-name-section` flag to the `wasm-bindgen`
command which will remove the `name` section of the wasm file, used to
indicate the names of functions typically used in debugging. This flag
is off-by-default and will primarily be controlled by wasm-pack,
typically being passed by default with `wasm-pack build --release`.
Closes#1021
This shaves a little over 2MB off the download locally for Linux,
removing debuginfo (which no one's probably gonna use anyway) as well as
switching from jemalloc to the system allocator.
The changes on master Rust insert debug sections now (yay!) but this means that
wasm binaries by default pick up debug sections from the standard library, so
let's remove them by default in wasm-bindgen unless `--debug` is passed
Currently errors are reported via Rust panics but there's lots more errors being
added over time so this commit starts the movement towards the `failure` crate
to more idiomatically report errors as well as provide better error messages
over time.
