thread '<unnamed>' panicked at 'attempt to subtract with overflow' #124

Open ttiimm opened 2 years ago

ttiimm commented 2 years ago

I'm hitting an issue trying to run simple-server=0.4.0 on Apple M2 hardware. I get this failure when trying to run the example, then making a request. I know the architecture isn't fully supported yet, but thought I'd bring the issue up.

Rust and Cargo versions

$ rustc -V
rustc 1.63.0 (4b91a6ea7 2022-08-08)

$ cargo -V
cargo 1.63.0 (fd9c4297c 2022-07-01)

Steps to Reproduce

  1. Run the example. $ RUST_BACKTRACE=1 UST_LOG="simple_server=info" cargo run
  2. Make a request to the server. $ curl localhost:7878

Note: also tried compiling with --target x86_64-apple-darwin option, but similar failure observed.

Another note: when running with version 0.3.0 I receive this message on the client side.

$ curl -v localhost:7878

zvolin commented 2 years ago

This is due to the behavior of httparse library.

When parsing a request with httparse, the returned request's method part is defined as Option<&'buf str> and here simple-server assumes that the reference points to the buffer's memory, however it is just a statically allocated str somewhere outside of a buffer, thus pointer arithmetic performed is invalid

zvolin commented 2 years ago

I am not sure whether this crate is still maintained, last merged PR was like 4 years ago? At least the method part should be reallocated during request parsing however from httparse docs it doesn't guarantee that any of returned slice is pointing to the buffer, only that those are str slices with lifetimes at least as long as buffer's one. For me it's relying on internals of the httparse dependency

Yeah, I ended up swapping out the crate with tiny-http, but thought I'd open a bug in case development starts back up again.
