There are some reports of users not being able to pass "enterprise" traffic through haproxy when using H2 because it doesn't emit CONTINUATION frames and as such is limited to headers no longer than the negociated max-frame-size which usually is 16 kB. This patch implements support form emitting CONTINUATION when a HEADERS frame cannot fit within a limit of mfs. It does this by first filling a buffer-wise frame, then truncating it starting from the tail to append CONTINUATION frames. This makes sure that we can truncate on any byte without being forced to stop on a header boundary, and ensures that the common case (no fragmentation) doesn't add any extra cost. By moving the tail first we make sure that each byte is moved only once, thus the performance impact remains negligible. This addresses github issue #249.
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)
