  • @mitogh: Flagging #209 Consider auto-deleting head branches after PRs are merged if folks have opinions about the approach
    • @flixos90: Makes sense after we’ve protected the branches that shouldn’t get deleted (trunk and release/*
  • @josklever: Had an issue where some images couldn’t be loaded on my WP dashboard and it was caused by a widgetWidget A WordPress Widget is a small block that performs a specific function. You can add these widgets in sidebars also known as widget-ready areas on your web page. WordPress widgets were originally created to provide a simple and easy-to-use way of giving design and structure control of the WordPress theme to the user. that was disabled in the screen options. It appears that all the widgets are loaded even if disabled. Would this be a performance improvement? Or is there a good reason to load resources for disabled widgets?
    • @adamsilverstein: Sounds like a core bugbug A bug is an error or unexpected result. Performance improvements, code optimization, and are considered enhancements, not defects. After feature freeze, only bugs are dealt with, with regressions (adverse changes from the previous version) being the highest priority., but don’t see a Trac ticket for it
  • @lu: Are we considering converting animated GIFs to MP4, similar to https://github.com/GoogleForCreators/web-stories-wp/issues/7232? Recently had to do this as the animated GIF size was huge compared to compressed/optimized video.
    • @spacedmonkey: Agreed that there are massive performance and file size wins there, but in Web Stories we converted GIF to MP4 using JSJS JavaScript, a web scripting language typically executed in the browser. Often used for advanced user interfaces and behaviors. in browser, which unfortunately won’t work in many WP contexts
    • @adamsilverstein: Could potentially provide a browser-based approach in core if server support is lacking
    • @andronocean: Would be concerned about server resource usage with larger GIFs or budget hosts
    • @gagan0123: If sever support is lacking, someone will have to do it manually rather than by CLICLI Command Line Interface. Terminal (Bash) in Mac, Command Prompt in Windows, or WP-CLI for WordPress. or cron job
    • @spacedmonkey: We used an ffmpeg library which requires array buffering, which isn’t available in older browsers and requires isolation of the page, meaning that images and scripts could not be hotlinked
    • @swisspidy: It’s doable, but there could be conflicts
  • @westonruter: Opened #220 Add Site Health test for full page caching (advanced cache)
