This enables DEBUG_MEMORY_POOLS and DEBUG_POOL_INTEGRITY so that by
default the tests run under stricter checks, which are likely to
catch more bugs. Note that these ones are permanently used in prod
on haproxy.org.
Sometimes figuring what differs between platforms is useful to fix
build issues, to decide what ifdef to add for example. Let's always
call $CC -dM -E- before starting make.
This patch cleans up the Windows CI to look more similar to the refactored
Linux CI on GitHub Actions.
It switches the environment set-up from some manual cygwin setup via choco to
the msys2/setup-msys2@v2 action which just works and allows later steps to look
like any others without need to manually specify the shell.
This new setup is much faster than before where a single Windows build required
more than 10 minutes with more than 5 minutes just spent setting up the
environment and more than 6 minutes compiling HAProxy.
With this patch the setting of of the environment is done in less than a minute
and HAProxy is compiled in less than 2 minutes.
The only drawback is that Lua does not appear to be readily available. I expect
this to be acceptable and that the benefits far outweight this small drawback.
