Notes

jedp - intend to implement navigator.requestSync and .unregisterSync

  • We intend to write an intend-to-implement email to dev-webapi and dev-platform
  • See: https://wiki.mozilla.org/Cloud_Services/FirefoxOS_Sync
  • To implement: https://github.com/slightlyoff/BackgroundSync/blob/master/explainer.md
    • "tell an application when it's a good time to sync"
    • "alarm API + network status changes"
  • Questions
    • any feedback on architecture of work in progress? https://bugzilla.mozilla.org/show_bug.cgi?id=1018320#c8
    • apart from implementing navigator.* in C++ (can't seem to add things to navigator object from JS), what else will we need to do in C++? (Exposing api to service worker through DOM?)
    • will we be able to implement scheduler in JS?
  • question: why not use fetch in service workers?
    • assurances provided by system to app instead of relying on periodic sync
    • may also provide ability for system to protect against malicious/errant apps
  • question: why are you trying to use system messages?
    • only a short-term goal until we have a shippable product
    • basically awaiting shipping Service Workers
    • there are partners needing an ability to wake themselves up and system messages achieve this for now
    • can't expose system messages to the web
  • turning this into a spec?
    • annevk suggests emailing public-webapps with a formal proposal
  • exposure?
    • UX for user approval of app's intention to sync data? "may affect battery life"
    • everything? when we move this away from system message wakeup mechanism, there will be an API change
      • which is concerning about exposing this to an ecosystem of developers we don't have direct influence over
    • when we're closer to landing this, let's re-evaluate moving to service workers, etc.
  • concern: memory pressure + completion of a sync in a service worker?
  • jedp: follow up with a list of apis we'll need in service workers and use cases
    • start a separate email thread on these
