This commit is a direct follow-up on the major rearchitecture of send buffering. This patch implements the proper handling of connection pool buffer temporary exhaustion. The first step is to be able to differentiate a fatal allocation error from a temporary pool exhaustion. This is done via a new output argument on qcc_get_stream_txbuf(). For a fatal error, application protocol layer will schedule the immediate connection closing. For a pool exhaustion, QCC is flagged with QC_CF_CONN_FULL and stream sending process is interrupted. QCS instance is also registered in a new list <qcc.buf_wait_list>. A new connection buffer can become available when all ACKs are received for an older buffer. This process is taken in charge by quic-conn layer. It uses qcc_notify_buf() function to clear QC_CF_CONN_FULL and to wake up every streams registered on buf_wait_list to resume sending process. |

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)
