It seems that our itests don't perform correctly in a high CPU usage
scenario such as running 6 tests in parallel. Some goroutines don't get
enough execution time and causes check to time out.
By reducing the total number of parallel tests, we hope to give all
goroutines some more breathing room.
To remove the need to have an extra make goal for the Windows itests, we
instead add the flag windows=1 that sets the make variable EXEC_SUFFIX
to properly add the ".exe" suffix to all executable names.
To make the Makefile a bit easier to understand, we remove the implicit
ITEST goal/command variable and switch all itest execution over to
explicit goals in the main Makefile.
Previous to this commit, running `make unit-cover pkg=xx`
would ignore the selected package and run unit tests and
coverage for all packages.
After this commit, the package selected with pkg= is the
only one that is tested and coverage output generated for.
If no pkg is selected, the default is as before, all pkgs.
In this commit, we modify the travis make directive to also compile all
the sub-severs using build flags. We do this as otherwise, we can only
detect mistakes in the build process of a sub-server via a manual
process. In this commit, we adapt travis to also cover this case.
The default is nolog, which prevents the unit tests in
the main pkg from being active, since otherwise they
would print as if they were being run like a dev build
of the daemon. Users can pass in custom tags when running
the Makefile by passing arguments using the log variable,
e.g. log="xxxxx xxx"".
This commit makes sure old log files are deleted before running the
integration tests. Previously new logs would be added to the existing
ones, causing a big mess. This was especially messy during flake
hunting, as all logs would be kept.
In addition, we now print the date before every start of the integration
tests, which is useful to see how long they have been running, for
instance in case of a deadlock.
