Hi everyone,

Over the weekend at PyCon Malaysia I've updated django-classy-tags and django-sekizai to 0.8.0 and 0.10.0 respectively.

Both releases only changed Python/Django compatibility.

Both now support:

- Python 2.7, 3.3, 3.4 and 3.5 (dropped 2.6)
- Django 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 1.10 (Added 1.10)

Hopefully this doesn't break everything (as it tends to do :D).

I also tried to update django-better-test to 1.10 (and I got it to support it), but travis-ci is being uncooperative so I had to delay the release.

Iacopo, please note that I've not released a better-test update yet, so my Dj1.10 compat changes are on https://github.com/ojii/django-better-test/tree/dj-1.10. Good number of tests failing though I have yet to reproduce it https://travis-ci.org/ojii/django-better-test. I should have time again this weekend (PyHack event), and I'll try to set up a VM with restricted resources because I think my laptop might be too fast to reproduce the issues on "slow" travis-ci.

Update: I am able to "reproduce" the test issues on my under-powered macbook air when simultaneously compiling some stuff (thus pegging the CPU at 100% usage). It's still non-deterministic and really odd, but at least I now sometimes get failing tests locally. The funny thing: It loses results (sub-tests aren't failing/succeeding unexpectedly, their result simply vanishes...).

Should anyone have ideas as to why high CPU usage breaks it, I'd love to hear it.

Managed to get the tests to work reliably (on Py 3.4 and higher). See https://github.com/ojii/django-better-test/pull/9

But had to remove Django 1.6 support (don't think too many people will get upset about this) and Py 2.7/3.3 are now "unstable". Without going to great lengths, I don't think I can fix that and I don't want to was too much time on ancient Python versions...

Iacopo, do you think this is good enough? Did you see issues in django CMS tests (py2) with tests being "unstable" (in the current version)?

Hey Jonas,

Thanks for the update.
Just to clarify, when you say "unstable", do you mean random failing tests? or just unsupported versions?

Potentially randomly failing tests on low performance machines due to unreliable multiprocessing. Though these issues seem to primarily manifest when doing bad things (leaking tests) our running in parallel mode with more processes than cores.

I had to give up trying to get the internal tests to pass on Travis. On 3.4 and higher I can explicitly use the spawn strategy in multiprocessing which has slightly higher overhead but is more reliable. On lower versions you cannot choose the strategy, python picks it based on the os.

As long as you use --vanilla on Travis you're safe, and on Travis you can't use any of the advanced features anyway, so using that flag makes sense.

I don't think it will have any impact: I'll give it a try during the
weekend.
django CMS 3.3 and below can still use the old version of better-tests

The old versions will suffer the same issues. This is not something newly introduced, but rather something fixed in 3.4 and above. Anyway, --vanilla should always work.

Thanks for the clarification; I'd say that the cms did not experience any side effect so far, but I'll apply --vanilla anywya
Thanks!
