Historically for size limitation reasons, we would only dump the backtrace of stuck threads. The problem is that when triggering a panic or other reasons, we have no backtrace, which effectively limits it to the watchdog timer. It's also visible in "show threads" which used to report backtraces for all threads in 2.4 and displays none nowadays, making its use much more limited. A first approach could be to just dump the thread that triggers the panic (in addition to stuck threads). But that remains quite limited since "show threads" would still display nothing. This patch takes a better approach consisting in dumping all non-idle threads. This way the output is less polluted that with the older approach (no need to dump all those waiting in the poller), and all active threads are visible, in panics as well as in "show threads". As such, the CLI command "debug dev panic" now dmups backtraces again. This is already a benefit which will ease testing of various locations against the ability to resolve useful symbols.

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)
