TST: Reproduce paintEvent failures #7294

GuillaumeFavelier · 2020-02-06T12:48:58Z

The goal is to fix the Azure failures encountered recently during testing in: #7290, #7235

The log is very scarce, I'm trying locally with virtualbox at the same time:

Closing now since this seems to be solved by #7295

GuillaumeFavelier · 2020-02-19T23:58:52Z

The failures still occur.

Reference:
#7342 (comment)

larsoner · 2020-02-22T21:32:30Z

Here is a nice readable traceback

GuillaumeFavelier · 2020-02-23T08:16:36Z

I was able to read it when you did the comment but I forgot to save the log, now the build is not available anymore. I remember it was related somehow to QVTKRenderWindowInteractor and PaintEvent.

larsoner · 2020-02-24T01:54:25Z

Just go through the recent Azure builds, it usually only takes looking at a few to find a failure with a good traceback, like:

Travis even hit one:

https://travis-ci.org/mne-tools/mne-python/jobs/655188026#L2938-L2944

GuillaumeFavelier · 2020-03-12T09:25:12Z

The latest commit 499f917 on #7380 seems to reproduce this behaviour on Travis consistently. I restarted the failed job 3 times.

GuillaumeFavelier · 2020-03-12T14:49:46Z

Reproduced in here, it appears to be consistent.

GuillaumeFavelier · 2020-03-12T14:51:25Z

My first idea is to use the renderer fixture in test_mixed_sources_plot_surface

GuillaumeFavelier · 2020-03-12T16:45:25Z

Test 1) is green
Test 2) is green
Test 3) is green
Test 4) is green
Test 5) ~~failed because of #7437, will be restarted once this is fixed~~ is green
Test 6) is green
Test 7) is green
Test 8) is green
Test 9) is green
Test 10) is green

GuillaumeFavelier · 2020-03-13T14:52:54Z

I ported 532aba9 in #7380

This reverts commit 7f6120b.

GuillaumeFavelier · 2020-03-17T12:38:03Z

Travis jobs are up in here, waiting for the good news 🤞

agramfort · 2020-03-17T13:21:50Z

thx @GuillaumeFavelier !

agramfort · 2020-03-17T13:21:51Z

mne/viz/_brain/_brain.py

+            times, array, self.interp_kind, axis=1,
+            assume_sorted=True)(time_idx)
+        ifunc = interp1d(times, self._data['time'])
+        act_time = ifunc(time_idx)


This PR undid (again) some of the refactoring. The way my commits worked:

the interpolators were set up once and reused (efficiency)

a helper _safe_interp1d (avoids bugs now back in master)

And this commit appears to have un-done these. Accordingly we have lost the efficiency and the singleton regression is back in master:

https://circleci.com/gh/mne-tools/mne-python/18710?utm_campaign=workflow-failed&utm_medium=email&utm_source=notification

I think the real (only) bug that probably needed to be fixed here had to do with calling the interpolation functions incorrectly, right? If so @GuillaumeFavelier can you make a revert commit for this PR and try making the minimal changes required to get CIs happy again? I'd rather not sacrifice the _safe_interp1d and funcs efficiency gains...

Ahh it's even more extensive -- I see this started out by completely reverting #7257. Are we planning on putting that back in somehow?

I updated #7162 and delayed thoses features to 0.21 for now
