Minutes

Go over action items of last meeting

  • Alex pushed a MAINTAINERS.md file to the git repo. It lists the current component maintainers.
  • Geneviève investigated how Eclipse plugins can be packaged and deployed.
    • p2 sites, can be hosted anywhere with an HTTP server
    • Marketplace, that is for Eclipse stuff only though
    • Eventual git trees and p2 sites could be on the project's download area at Eclipse, if needed

Committer definition and expectations

  • Matthew will do a write-up of the document and propose it to the others so it can be reviewed.

New default perspective

  • Matthew presented the new perspective proposal.
  • Geneviève will do a review of the Kibana tool, which apparently offers a great out-of-the-box experience.

Expanding JUL logging integration

  • We could eventually implement a special handlers to defers certain log calls (like warnings and above) to also log to the Error Log.
    • For now we will keep both APIs separate, so some places might have calls to both LOGGER.warning() and Activator.logWarning() for example.
  • Same with existing Eclipse tracing trace points (which is used for requests, signals, etc.)
    • Marc-André mentioned we could implement, and push to Eclipse upstream, a configuration window to configure the JUL setting, similar to the one used for Eclipse tracing. This would be more user-friendly than having to tweak a text file every time.
