Several bug reports were caused by shared libraries being loaded by other libraries or some Lua code. Such libraries could define alternate symbols or include dependencies to alternate versions of a library used by haproxy, making it very hard to understand backtraces and analyze the issue. Let's intercept dlopen() and set a new TAINTED_SHARED_LIBS flag when it succeeds, so that "show info" makes it visible that some external libs were added. The redefinition is based on the definition of RTLD_DEFAULT or RTLD_NEXT that were previously used to detect that dlsym() is usable, since we need it as well. This should be sufficient to catch most situations.
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)
