This test is inherently racy. It regularly pops up on the CI, and I've
spent one hour chasing a bug that apparently doesn't exist, just because
I'm running it 10 times in a row and it reports from 4 to 8 failures
when built at -O2 and generally even more at -O0. The logs are very
confusing, often reporting that it failed with status 0, with nothing
else wrong. I suspect it might sometimes be the shell command that fails
if it executes faster than haproxy finishes to start up, which would
also explain the relation with the optimization level. E.g:
> Testing with haproxy version: 2.2.0
> # top TEST reg-tests/seamless-reload/abns_socket.vtc FAILED (3.006) exit=2
> # top TEST reg-tests/seamless-reload/abns_socket.vtc FAILED (3.006) exit=2
> # top TEST reg-tests/seamless-reload/abns_socket.vtc FAILED (3.009) exit=2
> # top TEST reg-tests/seamless-reload/abns_socket.vtc FAILED (3.008) exit=2
> # top TEST reg-tests/seamless-reload/abns_socket.vtc FAILED (3.007) exit=2
> # top TEST reg-tests/seamless-reload/abns_socket.vtc FAILED (3.007) exit=2
> 6 tests failed, 0 tests skipped, 4 tests passed
Some of the failures include this, suggesting that some barriers could
help:
---- h1 haproxy h1 PID file check failed:
Could not read PID file '/tmp/haregtests-2020-10-09_11-19-40.kgsDB4/vtc.30539.04dbea7f/h1/pid
Since it has been causing false positives and consumed way more
troubleshooting time than it saved, let's mark it as broken so that it
doesn't waste more time. We can bring it back when someone manages to
figure what the problem is.
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)
