1. Status updates
2. Competing V4 AreaDetector Plugins
Planning for FRIB week:
3. Developer Meeting Topics (Monday, Friday AM)
4. EPICS V4 Introduction session
5. Any Other Business
Next Hangout: No ANJ on 4/21, so 4/14 or 4/28?
Present: MK, DH, UP, RL
AJ posted the wrong time on the Hangout invitation, apologies if anyone missed it because of that (the email agenda to the list was correct).
MK: Editing on developers guide, pvaPy doesn’t have support for unions yet, created a branch to implement that and show to him before agreeing how to complete.
AJ: Question about not using EZ (easy) in names.
MK: Probably too late to change that now.
DH: ADpvAccess uploaded, looking at pvTools, and adding different providers which Greg asked for and MS didn’t have time to do. Was working on docs and normative Types, waiting for input Greg.
RL: Nothing to report.
UP: Will be discussing this in the AD group, some NSLS guys will be attending too to discuss (Diego and Bruno). Either solution should be fine, hoping the V4 guys will tell us which is the better solution
DH: Fairly simple code just copying data, but Bruno’s code doesn’t copy the attributes. That’s one of the fairly substantial parts of my code. VAL field can be of any type but Bruno’s encoding uses the size of the data type, doesn’t handle unsigned data types, missing one of the timeStamp fields; Only attribute set is color mode, and that is done wrong. My solution uses zero-copy whereas he does copies.
AJ: Difference between interfaces?
DH: Not really, all have port, address, PV name. Follow standard AD pattern, his names are a bit more generic. Don’t know anyone who’s tried building mine (except me).
MK: Haven’t been keeping up with AD meetings, will try to attend.
DH: Tentative program shows wrong days…
AJ: I emailed Larry Hoff to try and change that. What subjects do we want to cover on the Monday & Friday AM.
AJ: pvRequest will come up…
MK: Talks will be based on Developers Guide, we’re working on updating that.
MK: Thurs 2pm to 4:15 we could fill that whole time, maybe with a break.
AJ: Suggest 2 hours if possible, to allow for a close-out talk at the end?
DH: Not very much time to do an API-level introduction. Sent Marty my ideas.
MK: We have to think carefully what we’ll cover, pick parts of the DevGuide.
DH: Need a subset of the guide for what we’ll cover.
MK: Agree what parts to cover, for each section and give simple examples for each.
DH: This is the TOC for the talk, possibly also for the DevGuide.
DH: What we can cover depends how much time we can get.
AJ: How much time do you want?
DH: Was basing this on a half-day. We can’t do all the above in 90 minutes. We could still do the Monday afternoon, we just don’t get to the V4 meeting.
AI on AJ: Andrew to talk to Larry to find out how much time we can get, email group.
AJ: Next meeting? Can’t do 4/21
MK: MS and I will be at BNL April 27-29.
AJ: Next week then if there’s anything to discuss.
