EPICS V4 Telecon, 2-Jun-2015
Agenda: Feedback from FRIB EPICS V4 training and EPICS meeting
Present: DH, MK, GW, RL, MD
MK: We started with a description of the toolkit that the Developers Guide describes. Praised the SNS guys for their use of V4 without having a V4 developer in their team. DH was giving the introductory talk.
GW: We did not have a separate session?
DH: We had a two-hour session in the main meeting.
I was going through all the introductory material: getting started guide, where the main documents are, the NT types documentation, giving pointers to everything, showing how and where to download and compile stuff - everything to get someone going.
Ran the examples: pvaSrv example and the pvDatabase example, showed the command line tools. Explained the terms, showed different providers. Presented the helloWorld example and an introduction to creating a service. Showed the APIs for creating structures and introspection interfaces.
GW: <sounds highly pleased>
What was the feedback? Any hints from the audience on what to do next?
DH: Not too much feedback on the talk.
For our plans; Diamond is interested in areaDetector. Would be interested in what ESS wants on the IOC side: is pvaSrv enough? Do they need more work on the IOC?
GW: has a whole list of issues collected while being there.
ESS had no development environment. People were interested but not exposed. Contact persons: Clemens ? and Timo Korhonen.
MK: Bob is trying to get ESS towards funding some V4 work.
GW: Don’t rely too much on these very preliminary plans. Other funding options might be interesting, too.
MK: Did you (GW) realize the decisions done in the f2f meeting?
GW: Yes. Also realized the freight train (move to GitHub) coming onwards.
Who will do the documentation changes?
MD: Will provide the minimal needed policy document.
GW: Wants to have detailed step-by-step guides. With illustrations.
MD: Will provide references to existing documentation where helpful.
MD: Posted a plan for the transition to github in email (last week).
AI: GW to review.
DH: Do you (MD) see everything being done by pull-request, or will some things be done as push?
MD: Agree that pull-request is not done for minutia. But it’s a fuzzy line where the difference is.
GW: I don’t want Marty to be held up in having to post merge requests for his own modules - like pvData.
MD: Well, I would like him to. If the effect is high, then he should.
GW: Ok, so I think we’re in agreement.
GW:MD: We won’t require pvDataWWW to go through the pull-request model, because that would require a shadow web site.
GW: When might we move over to the new model?
MD: Well, first requires Andrew to verify CI builders.
MK: Do please put the notes on how to use the github model in a place we can all see.
MD: OK, I’ll put it on the github wiki page.
Meeting ends 8:57 am PST
