[cctbxbb] new fail on windows

Mon Apr 25 00:48:11 PDT 2016

Dear Rob,

I beg to differ on that one. To me it certainly looks like the exclusion of Windows as a supported platform is currently intentional. And by 'currently' I mean that this is not a new thing, rather this has been the case since:

$ svn log -r 13380
------------------------------------------------------------------------
r13380 | rwgk | 2011-07-02 01:17:57 +0100 (Sat, 02 Jul 2011) | 1 line

libtbx/tst_easy_mp.py: skipping under Windows
------------------------------------------------------------------------
$ svn diff -c 13380
(..)
+  if (os.name == "nt"):
+    print "Skipping tst_easy_mp.py: Windows is not a supported platform."
+    return
(..)

Running tests on a Windows machine here or anywhere else will not make a difference when they are skipped internally.
Please note that libtbx.run_tests_parallel will always report the test as run successfully, and not as skipped.

Having said that, we (as in DIALS and xia2) would greatly benefit from full libtbx parallelization support on Windows, so we would welcome any development effort in that direction.

-Markus

Markus, I'd say that this is a wrong take on the current state of affairs regarding supporting Windows. I believe line 22 in easy_mp.py you refer to is supposed to be one of the last warnings one would get if one were to use some of the functions there with Windows in an unsupported manner, say if objects can't be pickled. I don't think it means this file was written with non-windows support intentionally.

I appreciate people code on different platforms but the way of working shouldn't be aloof denial of the existence of Windows. In the short term until you get a Windows PC perhaps Billy Poon might grant you access to one of the virtual Windows systems he has set up for testing. Otherwise I'm happy to run tests for you every now and then on my PC.

Regards,

Rob

Hi Nigel,

Should be resolved now.

It is true that we do not currently test on windows.
In this particular case it turns out neither does anyone else, cf. 
https://sourceforge.net/p/cctbx/code/HEAD/tree/trunk/libtbx/easy_mp.py line
22 which causes the other easy_mp tests to be skipped on Windows. This will make it kind of difficult to support windows software building on top of it, so at some point this needs to be addressed properly.

Best wishes & good weekend

-Markus

Hopefully this is fixed with r24353.

Afraid not. Is it true that you are not testing this windows feature on a 
windows machine?

Regarding junit, I'll talk with Aaron when he returns.

Cheers

Nigel
