MinHTTP

Minimal HTTP 1.0 and 1.1 parser and builder for requests and responses.

• no memory allocations
• no dependencies (only header used is stdint.h)

Inspired by picohttpparser. This project aims to have better performance and smaller size while having a builder feature.

How to Use

There is two options:

• Build library and include it in your project
• Just copy minhttp.c and minhttp.h to the proper locations in your project.

How to Build

1. mkdir build/
2. cd build/
3. cmake .. && cmake --build .

How to Test

In build/: ./test or ./test --quiet (for no output on success).

The tests are based on the ones from picohttpparser. Be aware that changes have been made due to difference between them:

• picohttpparser allows "keyless" values. This project doesn't
  • compare their "parse multiline" test and this project's "parse_headers_multiline_success_example_test" and "parse_headers_multiline_example_test" for a better visualization.

Roadmap

• parsers
  • pass all tests for request first line from picohttpparser
  • pass all tests for header parser from picohttpparser
  • pass all tests for response first line parser from picohttpparser
  • parse only requested headers (mh_parse_headers_set)
• builder
  • header builder
  • response first line builder
  • request first line builder
• benchmarking and optimizations
  • benchmark against other http parsers
    • picohttpparser
  • straight-forward parsing with no state machine
  • add likely and unlikely in all appropriate jumps
  • separate benchmark for header parsing and for first line parsing
  • enable NULL arguments for faster parsing
• misc
  • add code coverage percentage
  • add documentation on how to use
