  • @aristath shared an update ahead of time:
    • Autoloader: Work continues on to add a PHPPHP The web scripting language in which WordPress is primarily architected. WordPress requires PHP 5.6.20 or higher autoloader in CoreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress.. The results so far are encouraging and all tests (both manual and automated) has shown that performance is better and there are no apparent drawbacks. There are still a few minor things to polish, but it’s looking good so far.
    • L10nL10n Localization, or the act of translating code into one's own language. Also see internationalization. Often written with an uppercase L so it is not confused with the capital letter i or the numeral 1. WordPress has a capable and dynamic group of polyglots who take WordPress to more than 70 different locales.: Experimenting with different approaches and methods to refactor the way localization works in WP, in collaboration with @sergeybiryukov, @afercia and @poena. Still in the early stages of exploration, trying to find ways and methods to make the process more performant.
  • @joemcgill One thing that I wanted to bring up, was this post by @swisspidy about the new translations functionality he’s been working on. He has specifically asked for some performance help in that post, and I think it’s something that our team should take a look at. In the server timing research that I have been doing, I have found that processing translations can be a performance bottleneck for classic themes, specifically, so it would be nice if we could both help with this effort and improve performance overall for translated sites.

    • All work is now contained within our base feature branchbranch A directory in Subversion. WordPress uses branches to store the latest development code for each major release (3.9, 4.0, etc.). Branches are then updated with code for any minor releases of that branch. Sometimes, a major version of WordPress and its minor versions are collectively referred to as a "branch", such as "the 4.0 branch".
    • An holistic code review process is underway, where we’re going over all code contributed as part of this work and reviewing it in a single PR against trunktrunk A directory in Subversion containing the latest development code in preparation for the next major release cycle. If you are running "trunk", then you are on the latest revision.
    • Functional testing to follow on from the code review completion
    • Inline documentation review will follow from that

  • @flixos90 No major updates from my side, still working on assessing the best path forward for enhancing the lazy-loading logic in core, which will also benefit fetchpriority.

  • @joegrainger We have completed the initial infrastructure for the pluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the Plugin Directory or can be cost-based plugin from a third-party and have moved onto testing! This week we have started reviewing the infrastructure holistically and begun QA testing. Once testing is complete we will start work improving upon the initial architecture and moving towards building out the additional checks. Progress can be seen on the GitHub here. As always, feel free to take a look and leave any thoughts/ideas you may have in the repo. Thanks!

Creating Standalone Plugins

Contributors: @flixos90 @mukesh27 @10upsimon

  • @mukesh27 We finished engineering for Milestone 1 tasks and all PRs in final review. If anyone has some capacity please review. We are plaining to release our first WebP Uploads plugin soon.
  • @flixos90 +1, if we can get those final PRs merged tomorrow, the idea would be to publish the WebP Uploads standalone plugin on Thursday with the new automated workflow (which deploys the plugin based on the same codebase that the module uses)
    • Hopefully that all works out. Once the plugin is successfully released, we can proceed with the other ones (Dominant Color, Fetchpriority), and last but not least unify the currently 2 codebases from the SQLite plugin
