  • The jbuilder shift continues and more libraries are shifting. Any comments on https://github.com/mirage/mirage/issues/818 about this? The topkg/jbuilder integration now exists so releases of big things like datakit are pretty easy. (@avsm @samoht)

  • MirageOS 3 beta - it's so great and extant!

  • hack retreat update

18 January 2017

4 January 2017

14 December

  • mirage-types API changes update & discussion (see https://github.com/mirage/mirage/issues/698). the ongoing work around improving the interface's exposure of errors via result types is our last blocker for releasing MirageOS 3, and I (@yomimono) would greatly appreciate a sense of consensus around this issue.
    • FLOW.disconnect seems like a reasonable idea and unless there are objections @yomimono will attempt to include it this week.
  • CI: https://ci.mirage.io now active and tracking mirage-dev and mirage/opam-repository. (@avsm)
  • Mirage disk storage library RFC (@g2p)
  • Mirage feedback outcomes: I'm writing up a post about the results (https://gist.github.com/GemmaG/d7ad4149138548a622a4db2a16883cc5 - still a rough WIP) but will use the feedback to generate some actions we might want to consider in the new year. Feedback welcome! Thanks again to those who participated. (@gemmag)
  • hackathon update (@hannesm)
  • come back to beta1 (@mato)

30 November

  • Review new workflow patches with opam generation (@mato requested)
  • Do we open our FLOW error type? https://github.com/mirage/mirage/issues/698
  • MirageOS CI is now live(ish) @avsm
  • Performance harness work started with Takayuki Imada, @avsm @mor1 (@avsm)
  • Aarch64 interest? (@avsm)
  • Ideas for new logo (@gemma-gordon)
  • MirageOS 3 Update (@yomimono)

16 November

  • Release schedule
    • @yomimono had hoped to tag a beta on Tuesday, but is still working on API-breaking changes. Please keep eyes open for message before the end of the week. (If you want to help, see discussions on moving errors to result types and propagating them up and down chains of functors.)
  • Compilers
    • current master of mirage-xen and mirage-solo5 should be able to handle 4.04; please report bugs
  • Tests
    • travis was erroneously testing only unix backend for mirage repo; now does container builds for unix/xen/virtio/ukvm
    • progress on using datakit-ci for mirage?
      • @yomimono: I see that https://github.com/avsm/mirage-ci exists, would be nice to hear from @avsm about its status
      • @avsm: infrastructure fails everywhere, am provisioning new bare metal machines for the CI to run reliably, via Scaleway (x86) and packet.net (ARM)
  • Compiler hacking - see http://reynard.io/2016/11/16/CompHack.html for a writeup
    • anything that needs more work that participants want to draw attention to?
  • Performance harness - Takayuki Imada, Richard Mortier, @avsm to work on this for Mirage3 to run on an ongoing basis (issue to follow)

2 November

  • Solo5
    • TL;DR FreeBSD/bhyve is stable, Google Compute Engine support via solo5-mkimage
    • Consider doing a speculative refresh of the Solo5 C interfaces now, so that we go through any churn before 3.0 release rather than after?
  • Release:
  • Community
  • please fill in the anonymous google form with your feedback on the mirage call/catchup and general mirage issues. We've had 11 responses so far (thank you to those who participated!) but I have reopened it in the hope that we might get some more - tell me your views! (GemmaG)

19 October

  • Community
    • please fill in the anonymous google form with your feedback on the mirage call/catchup and general mirage issues. It will be closed on Monday 24th October. (from GemmaG)
  • compilers to target for MirageOS 3
  • MirageOS 3 API
  • MirageOS 3 targets
    • FreeBSD support via bhyve is coming along great thanks to @mato, @hannes, and @ricarkol's hard work
    • QubesOS currently stalled as @yomimono is distracted

5 October

  • Update on MirageOS announcement activity
  • MirageOS 3 API changes:
    • error handling
    • standardise on rresult?
    • hannes notes: result in mirage-types, define polyvar of error at top level (outside the module types) including a pp_error; rresult good for implementation libraries
      • yomimono: would be great to see proposals for specific polyvars there from someone who's used this style in a similarly general context
    • device connect
  • Mirage-dev status
    • 32bit testing anyone (on ARM)? Travis scripts using a 32bit compiler?
    • anyone already using 4.04?
      • (plan as yomimono understands it is to move support from 4.02/4.03 to 4.03/4.04 when 4.04 is released; it would be great to shake the bugs out early)

7 September

Mirage 3.0

Solo5

  • Solo5 tasks relevant for Mirage 3.0: https://github.com/Solo5/solo5/issues/82
  • @djwillia: Upcoming blog post about UKVM mentioning Solo5? Demonstrating how easy it is to add new backends with Mirage 3.0...

Pioneer Projects

  • Thanks for moving them over to Canopy, Hannes! (they are now here http://canopy.mirage.io/Projects)
  • Can everyone check any projects that they are mentoring to ensure they are up to date if not?
  • Can someone check tags? I used active project, head wanted for open ones, project done for finished ones. I also grouped some (like interfacing C and Irmin) which should be ungrouped and each subproject should have a slightly longer description.
  • Do we need more metadata in there? atm the author is either the person proposing/mentoring that project or the person doing that project, clearly we should record both. I removed Difficulty. See https://github.com/Engil/Canopy/issues/60 for feature requests
  • Time to add newly proposed projects? Propositions for new projects from @drup:
    • Unikernel gallery:
      • js_of_ocaml + Functoria
    • High level devices: Flexible API to cover all use cases for high level tasks
      Some suggestions for specific levels include:
      • deprecate mirage-seal
      • DNS server
      • syslogd device

Canopy use at ICFP

  • Features/elements we need for liveblogging/using Canopy during ICFP

Library Tracker

24 August

Mirage 3.0

Solo5 @DJWillia @mato

  • Wishlist for Mirage 3.0 - where best to put these? Add to above issue?

Library tracker

Pioneer Projects

  • Placement and details:
    • Move wiki content to canopy/other page that is easier to see? https://github.com/mirage/mirage/issues/569#issuecomment-235851380. @engil looking at some canopy updates relating to ICFP liveblogging in next few weeks - could add these features too (wanted, in progress or similar)
    • Move projects to issue trackers and track them that way?

Propositions for new projects from @drup:

  • Unikernel gallery:
    • js_of_ocaml + Functoria
  • High level devices: Flexible API to cover all use cases for high level tasks
    Some suggestions for specific levels include:
    • deprecate mirage-seal
    • DNS server
    • syslogd device

General management/tracking of projects @GemmaG
Difficult to follow which issues are most important/short term/longer term - Could use labels, assignees and milestones more effectively. See very very initial/basic example of how I'm going to start tracking OCaml Labs projects: https://github.com/ocamllabs/Projects/issues

Will be easier to surface easy skill-level tasks for others in community to work on etc.

ICFP

  • Not Mirage-specific, but anyone heading to ICFP/OCaml Workshop/ML etc etc might want to add info to this very large schedule (WIP) spreadsheet so we can all make sure we meet up/help eachother where we can with talks/workshops https://github.com/ocamllabs/Projects/issues/9 @sgrove
  • Mirage meet at ICFP!
  • Beginners tutorial for those interested... perhaps during OCaml workshop/CUFP sometime...
