[Bug 39927] New: Update the build VM

https://bugs.winehq.org/show_bug.cgi?id=39927

Bug ID: 39927
           Summary: Update the build VM
           Product: Wine-Testbot
           Version: unspecified
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

The current build VM is based on Debian 7.0 which is pretty old.
It would be nice to upgrade it to Debian 8.0.

* This might solve some issues with the VM sometimes going dead after a
Reconfig job.
  See: https://www.winehq.org/pipermail/wine-devel/2016-January/111059.html

* This would also get us a newer MinGW compiler. This would get us newer
headers, in particular for GetConsoleScreenBufferInfoEx(). Note however that
since this is a Vista+ API and the tests must still run on Windows XP it means
that specific API would still have to be loaded dynamically in order for the
test to be accepted in Wine. But it would make things easier for quick /
preliminary tests.

Mostly out of curiosity, why wouldn't we use the Wine headers like e.g. "make
crosstest" does?

--- Comment #2 from François Gouget  ---
The build VM is running Debian 8.6 with MinGW64 these days.

This initially looked like the compiler upgrade caused regressions but it turns
out the bugs were in the tests. So this is fixed.

This has brought up some instability in the build VM too: from time to time
restoring the live snapshot causes the guest kernel (3.16.0-4) to crash so that
the VM needs to be rebooted and the snapshot recreated. However that's a
separate issue (the guest kernel has now been upgraded to 4.7.0-0.bpo.1 in the
hope this will fix this issue).

Regarding the headers, the crosstest route does not give us a WineTest.exe so
we instead do a configure --host=x86_64-w64-mingw32 (or i686) which, based on
my previous comment, uses MinGW's headers. We could potentially change the way
we build the Windows binaries if there's a clear reason to.

Closing.
