Coverity has reported that cpu2 seems sometimes unused in
cpu_fixup_topology():
*** CID 1593776: Code maintainability issues (UNUSED_VALUE)
/src/cpu_topo.c: 690 in cpu_fixup_topology()
684 continue;
685
686 if (ha_cpu_topo[cpu].cl_gid != curr_id) {
687 if (curr_id >= 0 && cl_cpu <= 2)
688 small_cl++;
689 cl_cpu = 0;
>>> CID 1593776: Code maintainability issues (UNUSED_VALUE)
>>> Assigning value from "cpu" to "cpu2" here, but that stored value is overwritten before it can be used.
690 cpu2 = cpu;
691 curr_id = ha_cpu_topo[cpu].cl_gid;
692 }
693 cl_cpu++;
694 }
695
That's it. 'cpu2' automatic/stack variable is used only in for() loop scopes to
save cpus ID in which we are interested in. In the loop pointed by coverity
this variable is not used for further processing within the loop's scope.
Then it is always reinitialized to 0 in the another following loops.
This fixes GitHUb issue #2895.
HAProxy
HAProxy is a free, very fast and reliable reverse-proxy offering high availability, load balancing, and proxying for TCP and HTTP-based applications.
Installation
The INSTALL file describes how to build HAProxy. A list of packages is also available on the wiki.
Getting help
The discourse and the mailing-list are available for questions or configuration assistance. You can also use the slack or IRC channel. Please don't use the issue tracker for these.
The issue tracker is only for bug reports or feature requests.
Documentation
The HAProxy documentation has been split into a number of different files for ease of use. It is available in text format as well as HTML. The wiki is also meant to replace the old architecture guide.

- 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
