Depending on the timing, the second client that should be reported as a
client abort during connection attempt ("CC--" termination state) is
sometime logged as a server close ("SC--" termination state) instead. It
happens because sometime the connection failure to the server s1 is detected
by haproxy before the client c2 aborts. There is no retries and the
connection timeout is set to 100ms. So, to work, the client abort must be
performed and detected by haproxy in less than 100ms.
To fix the issue, the c2 client is now routed to a backend with a connection
timeout set to 1 second and 10 retries. It should be large enough to detect
the client aborts (~10s)
In addition, there is another race condition when the script is
started. sometime, server s1 is not stopped when the first client sends its
request. So a barrier was added to be sure it is stopped before starting to
send requests. And we wait to be sure the server is detected as DOWN to
unblock the barrier. It is performed by a dedicated backend with an
healthcheck on the server s1.
This patch should solve issue #1664.
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)
