Three types of frames may be padded : DATA, HEADERS and PUSH_PROMISE. Currently, each of these independently deals with padding and needs to wait for and skip the initial padlen byte. Not only this complicates frame processing, but it makes it very hard to process CONTINUATION frames after a padded HEADERS frame, and makes it complicated to perform atomic calls to h2s_decode_headers(), which are needed if we want to be able to maintain the HPACK decompressor's context even when dropping streams. This patch takes a different approach : the padding is checked when parsing the frame header, the padlen byte is waited for and parsed, and the dpl value is updated with this padlen value. This will allow the frame parsers to decide to overwrite the padding if needed when merging adjacent frames.
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 - 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)
