Supporting WSL in shell tests; was Re: [PATCH] Fix for EXE_SUFFIX being set for WSL having no effect

[Andrew Luo]

On WSL, “uname -s" will print Linux, however one can distinguish between WSL and “true” Linux by “uname -r" containing Microsoft.  However, in WSL we can build both a WSL Linux target, or a WSL Windows target, which means we have to either check the JDK-under-test (check if it is a Windows or Linux JDK) or have some environment variable to indicate such.

Thanks,

-Andrew

I think it is only natural to expect folks to debug shell tests directly. If we accept this assumption, then, is there any reasonable alternative to “uname"? There is a “systeminfo” tool on windows, not sure if it helps. We really need to know what “uname -s” outputs, though, as it might still work.

It would help if we could crowd-source a table showing the value on different systems.
