It's common to see process_stream() being woken up by wake_expired_tasks in the profiling output, without knowing which timeout was set to cause this. By making it possible to record the call places of task_queue() and task_schedule(), and by making wake_expired_tasks() explicitly not replace it, we'll be able to know which task_queue() or task_schedule() was triggered for a given wakeup. For example below: process_stream 51200 311.4ms 6.081us 34.59s 675.6us <- run_tasks_from_lists@src/task.c:659 task_queue process_stream 19227 70.00ms 3.640us 9.813m 30.62ms <- sc_notify@src/stconn.c:1136 task_wakeup process_stream 6414 102.3ms 15.95us 8.093m 75.70ms <- stream_new@src/stream.c:578 task_wakeup It's visible that it's the run_tasks_from_lists() which in fact applies on the task->expire returned by the ->process() function itself.
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)
