Willy reported that since 3ac79b504 ("MEDIUM: server:
make server_set_inetaddr() updater serializable"), haproxy fails to
compile on some older compilers such as gcc-4.4 with this kind of error:
src/server.c: In function 'snr_resolution_cb':
src/server.c:4471: error: unknown field 'dns_resolver' specified in initializer
compilation terminated due to -Wfatal-errors.
make: *** [Makefile:1006: src/server.o] Error 1
This is due to referencing a member inside anonymous union from a compound
literal assignment. Apparently such use of anonymous union wasn't properly
supported back then on older compilers. To fix the issue, we give "u" name
to the parent union use this name to explicitly refer to the union where
relevant in the code (only a few changes fortunately).
The fix itself was verified to restore build compatibility with gcc 4.4
(and even 4.2).
As 3ac79b504 is used as a prerequisite for 64c9c8ef3 ("BUG/MINOR:
server/dns: use server_set_inetaddr() to unset srv addr from DNS"), please
consider backporting this patch too if 64c9c8ef3 happens to be backported
in 2.9.
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)
