Revisit 'another set in progress'

6

Some ideas in https://github.com/bluesky/ophyd/pull/755 were deferred in favor of simpler approach that could be back-ported to v1.3.x. Let's visit them.

Common intermittent test failure

1

This has appeared a lot in build logs. Seems to fail 10-20% of the time: ``` __________________ test_default_configuration_smoke[pyepics] ___________________ ad_prefix = 'ADSIM:' cleanup = @pytest.mark.adsim def test_default_configuration_smoke(ad_prefix, cleanup): class MyDetector(SimDetector):...

Migrate from Travis-CI to GitHub Actions

See bluesky/bluesky-enhancement-proposals#21 for details.

Run one process per container

1

In #936, we rely on an image based on https://github.com/klauer/simioc-docker for `test_epicsmotor.py`. It is unmaintained, and it runs multiple IOCs in one container, which is against best practice and make...

Segfault observed in GitHub Action executing pytest

This might be a one-off, just leaving this here for later reference. Will close if it doesn't come up again in the near future. ``` Run coverage run --concurrency=thread --parallel-mode...

Discuss: Issue a warning if a Status' default timeout is None?

Refactor Signal to make hooking in custom _set_and_wait easier.

Following up on this comment: https://github.com/bluesky/ophyd/pull/749#issuecomment-535996052 @klauer @ZLLentz Did work along these lines already make its way into pcdsdevices?

Python-level dead band

Different experiments might call for different levels of precision in tracking changes in, say, the beam current. One user might want a detailed data dump, another might want a shorter...

In `CamBase` we capture some components common to all AD cameras as configuration. But there are probably some device-specific components that should also be captured.

Currently, even the simplest area detector configurations require defining custom classes in beamlines' IPython profiles. There is no full-featured AD class built in to ophyd. This makes setting up an...
