Adds a Vegeta-powered HTTP server benchmark at src/std/net/http/benchmarks/http-benchmark.ss and native HTTP/1.1 tests in src/std/net/http/server/server-test.ss. The benchmark requires Vegeta and GNU timeout; build/run instructions are in its source.

Test results

43 cases: 29 passed, 14 failed, in both source and optimized execution.

Fixing the failing HTTP behavior is TODO in an upcoming PR.

Failing tests:

  • Request without HTTP version rejects before dispatch.
  • POST Expect: 100-continue precedes body and final echo.
  • Mixed-case Host, tab whitespace, and empty field are accepted.
  • Invalid field-name token rejects before dispatch.
  • Missing Host rejects before waiting for the declared body.
  • Different duplicate Host authorities reject before dispatch.
  • Case-insensitive duplicate Host rejects before dispatch.
  • Arbitrarily large negative Content-Length rejects before dispatch.
  • Negative Content-Length rejects before dispatch.
  • Nondecimal Content-Length rejects before dispatch.
  • Field value control byte rejects before dispatch.
  • Invalid request prefix rejects before dispatch.
  • Bare carriage return before another field rejects before dispatch.
  • Case-varied Transfer-Encoding and Content-Length conflict rejects.

Adds a [Vegeta](https://github.com/tsenart/vegeta)-powered HTTP server benchmark at `src/std/net/http/benchmarks/http-benchmark.ss` and native HTTP/1.1 tests in `src/std/net/http/server/server-test.ss`. The benchmark requires Vegeta and GNU `timeout`; build/run instructions are in its source. ### Test results **43 cases: 29 passed, 14 failed**, in both source and optimized execution.

great work, thank you!

do you think it is worth strengthening the server checks to respond according to spec on client errors?
