In507223d5("MINOR: log: global lf_expr node options"), a mistake was made because it was assumed that only the last occurence of %o (LOG_FMT_GLOBAL) should be kept as global node options. However, although not documented, it is possible to have multiple %o within a single logformat expression to change the global settings on the fly. For instance, consider this example: log-format "%{+X}o test1=%ms %{-X}o test2=%ms %{+X}o test3=%ms" Prior to3f2e8d0ed("MEDIUM: log: lf_* build helpers now take a ctx argument"), this would output something like this: test1=18B test2=395 test3=18B This is because global options is properly updated as the lf_expr string is parsed. But now due to507223d5and3f2e8d0ed, only the last %o occurence is considered. With the above example, this gives: test1=18B test2=18B test3=18B To restore historical behavior, let's partially revert507223d5: to compute global node options, we now start with all options enabled and then for each configurable node in lf_expr_postcheck(), we keep options common to the current node and previous nodes using AND masking, this way we really end up with options common to all nodes. No backport needed.
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)
