Sugar dev meeting

From OLPC
Jump to navigation Jump to search

About

  • Quick update about what we have been working on and eventually the problems we have run into.
  • Discussion about the implementation details of tickets we are planning to work on. Figure out how to split up the work and who should be owning the various parts.
  • Questions from activity authors about specific aspects of the platform and more in general on how to better integrate their activity in Sugar. Report about problems they run into.
  • Help out new contributors to figure out where to start. Point out the tickets we need help with, discuss with them the implementation.

When and where

  • weekly
  • thursday
  • 17.00(UTC)
  • irc.freenode.net, #olpc-meeting

Every tuesday on irc.freenode.net, in the #olpc-meeting channel. Since people from the outside might not have the time to join weekly we will alternate in big and small meetings. The big meeting will try to be more general to allow to get the big picture. The first meeting in 2008 (19th February) was a big meeting so the 26th February will be a small one and so on... To convert UTC to your local time, take a look at http://fedoraproject.org/wiki/Infrastructure/UTCHowto or run: date -d '2008-02-18 17:00 UTC'

Who

The meeting is mainly targeted to Sugar core and activity developers, but everyone interested is welcome to join. It's primary purpose is to try to open up a bit the development, make it more transparent and allow the community to participate more easily. For when to join best see 'When and Where'.

Topics

  • discuss eben's sugar todo list: http://lists.laptop.org/pipermail/sugar/2008-April/004909.html
    • We found out that eben's list is basically not controversial and that we 'only' need to prioritize the topics :p
      • action item: prioritize the topics
    • Expose an avatar property for buddies in the ps
      • daf stated that we have specific support for avatars in Gabble, which uses hashes, and therefore would reduce overhead.
  • AlertBox for use with palettes/notifications
    • mockup: http://wiki.laptop.org/go/Specifications/Object_Transfers#Preliminary_Mockups
    • sumup:
      • an object transfer error occurs.
      • create a new palette and embed an alertbox in it.
      • create a notification object.
    • attach the new alert palette to both the notification and the transfer object in the frame.
      • Then, upon the cancel/retry button callback: make sure that the notification is gone, reattach the old palette, take the appropriate action.
    • action items:
      • a) create an AlertBox class (probably a subclass of alert or make alert more generic)
      • b) add support for more complex layout to Palette class (ability to set the content before and/or after the menu independently)
  • Activity bundle format, autoupdate
    • Homunq has a proposal up at Talk:Activity_bundles#Proposals_for_update
    • two proposals: a philosophical one about where we want to get to, including activity threading with forks, and an implementation one, which only covers activities as long as the signing key stays the same.
    • Philosophically:
      • Eben says any change of key should count as a different activity
      • Homunq argues that still grouping them in the UI will allow tighter control of keys, and that the UI can give appropriate guidance on secure practices.
      • Agree to disagree for now, because implementation is not urgent.
    • Implementation Signatures
      • morgs has minor comment about hash format (hex instead of base64, for easier comparison
      • no further comments
      • homunq will start work this week
      • unresolved issue: how to store private key for signing an activity?
        • we need to talk to m_stone .

Search/replace is a mess but anything else, go ahead and start posting bugs. http://dev.laptop.org/git?p=activities/develop;a=summary . To resume editing on the activity bundles it creates, you need to use the DoppelJournal activity (included in the git tree), which is a renamed copy of journal with the relevant bug fixed. Homunq 09:43, 18 March 2008 (EDT) "git clone git://dev.laptop.org/activities/develop"
