qc_send() was systematically called by quic_conn IO handlers with all instantiated quic_enc_level. Change this to only register quic_enc_level for send if needed. Do not call at all qc_send() if no qel registered. A new function qel_need_sending() is defined to detect if sending is required. First, it checks if quic_enc_level has prepared frames or probing is set. It can also returns true if ACK required either on quic_enc_level itself or because of quic_conn ack timer fired. Finally, a CONNECTION_CLOSE emission for quic_conn is also a valid case. This should reduce the number of invocations of qc_send(). This could improve slightly performance, as well as simplify traces debugging.
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)
