@flixos90

GitHub project

• @mxbclang: Review the module proposal workflow and leave any feedback on the PR
  • @flixos90: We’ve been working on this to have a long-term plan for each module; want to avoid a module going into the plugin and growing stale without any iterations or next steps
  • @jeffpaul: I’ll review with an eye from the core perspective
  • @flixos90: Another benefit of this documentation is that it includes a high-level overview of how to propose a feature project for core, which isn’t really documented right now; this could be a good starting point for the future
• @olliejones: Might be cool to have a stub performance-lab module for modification by would-be contributors
  • @flixos90: That’s a great idea, though there would be little to start with since a module can be pretty much anything. The best place to start right now is with the writing a module doc, though that’s more about the technical starting point and the new proposal doc is more about overall workflow.
• @flixos90: Released v1.1.0 yesterday. Next release will be 1.2.0 on Monday, June 20, so we should target merge for anything for that release by about June 15.

Open floor

• @olliejones: Following up on the large site/many users work: https://core.trac.wordpress.org/ticket/55749
  • Have a new plugin to address the issues outlined there
  • Might be a candidate for a Performance Lab module
  • These issues are mostly fixable with filters and actions, but not completely
  • @adamsilverstein: Looks like a core side issue; the TracTrac An open source project by Edgewall Software that serves as a bug tracker and project management tool for WordPress. ticketticket Created for both bug reports and feature development on the bug tracker. describes hte issue better. Is the issue specific to the REST endpoint or more generally about how the user query is constructed?
  • @olliejones: It’s actually central to WP_User_Query and WP_Meta_Query, but at the same time the REST endpoint’s set of parameters doesn’t allow for avoiding the query-pagination overhead
