Introduction

This is a library for creating HTTP/2 servers.

To see some introductory docs, please check the Hackage page or the file hs-src/SecondTransfer.hs.

Supported platforms

At the moment, we support both Linux and Mac OS X. We haven't tested the library in Windows, but off the top of my head I can not think on any too Unix specific thing that we are using.

Building and installing

The preferred method of installing SecondTransfer is through Stack. SecondTransfer uses Botan for its TLS layer, but the default build disables the library to play nice with Stack's build servers. Enable it by installing Botan in your preferred location, switching on the flag enable-botan (you can do that in your stack.yaml file) and adjusting the necessary include directories (through extra-include-dirs and extra-lib-dirs, also in stack.yaml).

We use a extensible TLS mechanism, so if you would rather use a recent version of OpenSSL, look for the typeclass TLSContext and implement it.

Running the tests

There are two sets of tests: normal Haskell tests and a custom test suite called Suite 1 that requires Stack, Python 3.4+, Redis running in localhost/standard port with DB 3 erasable, and Numpy. To run Suite 1, SecondTransfer should be compiled with the "Monitoring" flag enabled.

Example

There is a very basic example at tests/tests-hs-src/compiling_ok.hs, and a somewhat more complicated one at examples/attempt_bust; that one shows how to do HTTP/2.0 push from the library.

Development

Uploading documentation (provided you have access to the package in Hackage):

$ ./hackage-upload-docs.sh second-transfer 0.5.4.0 <hackage-user> <hackage-password>

Running with instrumentation

Use this:

LD_PRELOAD=/usr/local/lib/shimmercat-build/deps/libasan.so  SAN_OPTIONS=verbosity=1:help=true shimmercat devlove
