Dear Contributors,

We had a period full of exciting things in the last couple of months, SIP May meeting is one of them! More about Scala Center’s recent activities, please click here.

Just after Scala Days Belin closed, on 18th of May we have organized a Contributors Summit co-located with Typelevel Summit hosted by Zalando in Berlin. Having 6 out of 9 Committee members at the same time in the same room made scheduling easier (o:

Given that Scala 3 is coming our way by 2020, the Committee had a lot to discuss - what is the SIP role in this transition, how to organize the meetings, the approach the long list of changes and what is the best way to include the community in the process.

Opening Remarks

Quorum was not met, but the meeting still took place in a form of an open discussion.

The meeting was devoted to discussing how SIP Committee should handle the approval of Scala 3 changes into the specification and how it would organize during the next year, given that Scala 3 will be feature freeze by then.

Topics discussed:

  1. SIP Committee role in the upcoming Scala 3 release.

All present agreed that SIP Committee should continue its mandate in approving the Scala 3 changes.

  1. SIP Committee role in Scala 2

SIP Committee will focus on Scala 3 changes and creating the spec, Martin (YouTube time: 6’54’’), Scala 2 SIP proposals will continue as before, but at a slower pace.

  1. How to structure and organise the workflow

Given the short time and amount of decisions that need to be made, the Committee proposed and agreed about the following

Structure

a) Have a list of changes , grouped in batches that would be decided within the next year, meeting once a month b) Plan - full and strucutured list of changes that need to be implemented consolidated between the Committee members using a shared a Google doc c) Public comments - each batch should be published on the Contributors thread, for a month at a time in order to have community involved, share their opinion and contribute. Advise was proposed - each thread should clearly point out start and end date of collecting the comments/suggestions.

Organisation

Jorge will be in charge of posting the monthly batches on contributors thread. One of the Committee Members (SIP reviewer) or SIP author will be assigned/volunteer to follow the conversations, answer questions and finally summarize the discussion to be submitted to the Committee in order to make inclusive decision. The first batch should be the removals as per list already prepared for 2.14 release.

The above mentioned structure and organisation was gathered throughout the meeting, here are the snippets:

  1. Other: spec, quorum

Heather bings up an important question “What about Scala spec” (YouTube time: 4’49’’) to which Martin responds within the next year we should know which features are included as a first priority but that spec should not be left for the last minute.

Miles (YouTube time: 8’45)suggested that SIP proposals should include draft specification changes to save time and effort pulling the eventual spec update together.

Martin (YouTube time: 37’59’’) also raised a question about the decision making process, asking if it would be better to change to simple majority when it comes to voting. This was rejected by most of the Members and agreed it should be discussed in a different meeting or time.

Conclusion The first batch should be agreed upon, posted on the Contributors thread for public comments. Such discussion should be summaraized and included in the next meeting (22nd June 2018, after ScalaDays NewYork).

Are we still on schedule for this? I can’t figure out from the minutes who will be responsible for compiling these lists.
