Improving error handling (`wp_die()` replacements)

@callumbw95 opened ticketticket Created for both bug reports and feature development on the bug tracker. #64009, which proposes reviewing and updating existing wp_die() calls that currently result in 500 errors. The goal is to establish a more consistent approach to error handling and reduce unnecessary error entries in logs.

@westonruter agreed on the approach: “Since WordPress has always been about semantic markup, it makes sense that it use semantic HTTPHTTP HTTP is an acronym for Hyper Text Transfer Protocol. HTTP is the underlying protocol used by the World Wide Web and this protocol defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands. status codes as well. In the same way we don’t use <div> for everything, wp_die() shouldn’t use 500 for everything”.

@callumbw95 added that “the added benefit is that the debug logs will reduce in size as there are a lot of errors that can be resolved client side (401, 403, etc) that don’t need to sit in the error logs”.

Template Output Buffering

The risk is considered low, though there are concerns about potential effects on TTFB and plugin behavior. Clear documentation and testing will be needed.

@westonruter identified ticket #43258 on output buffering as the current biggest blockerblocker A bug which is so severe that it blocks a release.. He explained that while there’s been significant discussion both on the PR #8412 and in Slack, the debate centers around the trade-offs between enabling full-page buffering (to allow post-render optimization) versus keeping the door open for streaming, which could improve initial load performance. He provided further context on how classic themes already stream via procedural rendering, while blockBlock Block is the abstract term used to describe units of markup that, composed together, form the content or layout of a webpage using the WordPress editor. The idea combines concepts of what in the past may have achieved with shortcodes, custom HTML, and embed discovery into a single consistent API and user experience. themes generally do not.
- @westonruter noted that while streaming isn’t widely adopted in WordPress today, it could become valuable in the future, and care should be taken not to block its evolution. He also shared a WPDirectory search of flush() usage across coreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress., noting they appear mostly in adminadmin (and super admin) and XML-RPC contexts rather than template rendering.
- @westonruter asked if anyone has insights into this area and can contribute thoughts on how we can bridge these two perspectives, allowing for a default output buffer while also enabling streaming if the application wants it. He’d be most thankful.
@b1ink0 brought up PR #9867 related to footer script module support and noted that @jonsurrell had provided thoughts around dependency handling.

@westonruter mentioned new guidance on AI-generated contributions now available in the Performance repo, including a new AGENTS.md file and updated PR template instructions with PR #2193. He explained that this was prompted by a recent increase in AI-assisted PRs, some of which indicated the AI’s output wasn’t being carefully reviewed by the contributor.

Open Floor

@westonruter introduced Trac ticket #64066, proposing that WordPress default to moderate eagerness for Speculative Loading, when caching is detected. He noted the idea could provide a performance boost in WordPress 7.0 by improving preload efficiency on cached sites, but also acknowledged the need to weigh sustainability concerns around increased server load.
- @mukesh27 asked whether a second opinion was needed, and whether any Google team members had provided feedback.
- @westonruter replied that he had received positive input from Google, though their priorities don’t always align with those of hosts and site owners. He noted that moderate eagerness can increase bandwidth usage due to unnecessary preloads and may lead to added hosting costs.
- @gilbertococchi shared his thoughts, emphasizing that moderate eagerness could be significantly more impactful than conservative loading, especially with Chrome’s recent introduction of a Viewport Heuristic, but stressed the importance of safeguards like persistent object caching to mitigate server load.
- @mukesh27 summarized that @gilbertococchi was supportive of the proposal and encouraged moving the ticket into the 6.9 milestone for visibility.
- @westonruter clarified that while he wasn’t necessarily aiming for inclusion in 6.9, he agreed to milestone the ticket for tracking purposes, with the understanding that it may still be punted.

@psykro – personal plan is to get the Abilities post published close to the 6.9 release, the MCP adapter post soon after, and then follow up with the PHPPHP The web scripting language in which WordPress is primarily architected. WordPress requires PHP 7.4 or higher AI SDK post. The aim is to try to build something that ties all three together so they can be read as a three-part series or individually. The proposal by @juanmaguitar for templates was suggested to be used as an example.

The new content items approved and @bph will create the issues later next week and assign them to writers.
