To perform the mux-to-mux data fast-forwarding, 4 new callbacks were added into the mux_ops structure. 2 callbacks will be used from the stconn for fast-forward data. The 2 other callbacks will be used by the endpoint to request an iobuf to the opposite endpoint. * fastfwd() callback function is used by a producer to forward data * resume_fastfwd() callback function is used by a consumer if some data are blocked in the iobuf, to resume the data forwarding. * init_fastfwd() must be used by an endpoint (the producer one), inside the fastfwd() callback to request an iobuf to the opposite side (the consumer one). * done_fastfwd() must be used by an endpoint (the producer one) at the end of fastfwd() to notify the opposite endpoint (the consumer one) if data were forwarded or not. This API is still under development, so it may evolved. Especially when the fast-forward will be extended to applets. 2 helper functions were also added into the SE api to wrap init_fastfwd() and done_fastfwd() callback function of the underlying endpoint. For now, this API is unsed and not implemented at all in muxes.
The HAProxy documentation has been split into a number of different files for ease of use. Please refer to the following files depending on what you're looking for : - INSTALL for instructions on how to build and install HAProxy - BRANCHES to understand the project's life cycle and what version to use - LICENSE for the project's license - CONTRIBUTING for the process to follow to submit contributions The more detailed documentation is located into the doc/ directory : - doc/intro.txt for a quick introduction on HAProxy - doc/configuration.txt for the configuration's reference manual - doc/lua.txt for the Lua's reference manual - doc/SPOE.txt for how to use the SPOE engine - doc/network-namespaces.txt for how to use network namespaces under Linux - doc/management.txt for the management guide - doc/regression-testing.txt for how to use the regression testing suite - doc/peers.txt for the peers protocol reference - doc/coding-style.txt for how to adopt HAProxy's coding style - doc/internals for developer-specific documentation (not all up to date)
