ev3dev-stretch #52

Open dlech opened 6 years ago

dlech commented 6 years ago

How do you plan on handling breaking driver changes in ev3dev-stretch? For example, port names and LED names have changed.

kortschak commented 6 years ago

My approach in the past has been to support the most recent needed ev3dev version. This could be extended to only support the current major version, but place a git tag at the last jessie-supporting commit so people can manually check that out. Do you have any suggestions?

dlech commented 6 years ago

That sounds reasonable. I'll probably start advertising ev3dev-stretch as "beta" soon. Personally, I don't use jessie anymore at all at this point. So, I'm just wondering how to test #50 without having to go back to jessie. My plan is to just update my local copy of https://github.com/ev3go/ev3.

The other alternative is to guard the name constants with build tags, but that adds complexity to support and I probably won't do that.

kortschak commented 6 years ago

BTW Can you point to new naming conventions?

basically, EV3 ports have a prefix of ev3-ports: now and LEDs are something like led0:green:brick-status.

I have decided the best way to do this is to make a persistent jessie branch from the point where the changes occur. This allows a period of bug maintenance after the fork for people who stay with jessie.

I have a couple of branches ready for PRs for the stretch transition. I need to look at the BrickPi to see what changes need to happen there (just LEDs from the looks of it).

https://github.com/ev3go/ev3dev/tree/ev3dev-stretch https://github.com/ev3go/ev3/tree/ev3dev-stretch https://github.com/ev3go/brickpi/tree/ev3dev-stretch

Feel free to try them out - I've done minimal on-platform testing at this stage, and will only be able to get to that likely late in the week.

Do you have a time frame for the change over for ev3dev to stretch?

dlech commented 6 years ago

Optimistically, I would like to start advertising stretch as "beta" by the end of the year. We'll see if that actually happens or not.
