Dev Chat Summary: December 12th

Dev Chat Scheduling

As many folks will be away over the Christmas/New Year period, the next few meetings will be as follows:

  • December 19: Normal meeting.
  • December 26: Normal meeting will not be happening. There are likely to be coreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress. folks around to answer questions for an open floor session.

5.0.2 Schedule and Scope

Please note that WordPress 5.0.1 has just been released, so any previous mentions of scope or schedule for WordPress 5.0.1 should now be read as applying to WordPress 5.0.2.

WordPress 5.0.2 is intended to be released two weeks after WordPress 5.0, which would make the release date December 20. To give a little more space before the Christmas/New Year holiday period, I’ve proposed that it be released December 19.

Milestone Dates

5.1 Schedule and Scope

As there are already over 200 tickets fixed in WordPress 5.1, I’d like to propose that WordPress 5.1 has a relatively short release cycle.

Milestone Dates

  • BetaBeta A pre-release of software that is given out to a large group of users to trial under real conditions.

A key point from the WordPress 5.0 cycle was that it demonstrated the value of having a hard feature freeze at beta 1, as well as string freezes and strict 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. fixing policies during the release candidate phase. With that in mind, I’d like to propose that we retain these policies for the WordPress 5.1 cycle.

The tickets already fixed in WordPress 5.1 need to be reviewed, to ensure they’re all stable for release in this cycle.

Apart from that, the PHP upgrade warnings and the White Screen of Death protection from the Site Health Check project are currently the only uncommitted features scheduled for WordPress 5.1. The PHP upgrade warnings are currently soft warnings, ahead of the minimum PHP version bump proposed for April 2019.

Backwards Compatibility Breaks in 5.0.1

5.0.1 was just released to fix several security bugs. The Security team tried very hard to mitigate all of the vulnerabilities without any back-compat breaks, but unfortunately there were a few cases where that was not possible.

Security patches are backported to the 3.7 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"., so these BC breaks also apply to versions 4.9.9, 4.8.8, etc.

Form element no longer passes KSES

Prior to 5.0.1, the $allowedposttags array contained an entry for the <form> element and some of its attributes. Because of that, Contributors and Authors could use it in posts.

The element was removed in 5.0.1, except for situations where a 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 WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party has explicitly registered input or select fields via the wp_kses_allowed_html filterFilter Filters are one of the two types of Hooks https://codex.wordpress.org/Plugin_API/Hooks. They provide a way for functions to modify data of other functions. They are the counterpart to Actions. Unlike Actions, filters are meant to work in an isolated manner, and should never have side effects such as affecting global variables and output.. If a Contributor or Author includes <form> in their post, it will be removed when the post is saved. It will also be stripped from arbitrary content that plugins pass to wp_kses_post() or wp_kses_allowed_html( 'post' ).

If a plugin author wants to restore the original behavior, they will need to add form, input or select tags via wp_kses_allowed_html. Please exercise caution when doing so, because this could re-introduce a vulnerability. Make sure only trusted users are allowed to add <form> tags. 

meta_input, file, and GUID inputs are ignored

Prior to 5.0.1, $_POST requests for creating posts could contain values for meta_input, file, and guid. This is no longer true, and values passed for those fields will be ignored.

Plugins should not manually manipulate $_POST, but rather use the appropriate filters, and always validate/sanitize any data coming from an untrusted source.

MIME validation for uploaded files

Prior to 5.0.1, WordPress did not require uploaded files to pass MIME type verification, so files could be uploaded even if the contents didn’t match the file extension. For example, a binary file could be uploaded with a .jpg extension.

This is no longer the case, and the content of uploaded files must now match their extension. Most valid files should be unaffected, but there may be cases when a file needs to be renamed to its correct extension (e.g., an OpenOffice doc going from .pptx to .ppxs).

WordPress Branch Status Update

Thank you everyone for helping work through this slightly different commit management process during the WordPress 5.0 release.

There’s some cleanup work to be done before we can get back to normal, but this shouldn’t take too long. There are 283 commits made to the 5.0 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". that need to be reviewed and ported to trunk. During WCUS Contributor DayContributor Day Contributor Days are standalone days, frequently held before or after WordCamps but they can also happen at any time. They are events where people get together to work on various areas of https://make.wordpress.org/ There are many teams that people can participate in, each with a different focus. https://2017.us.wordcamp.org/contributor-day/ https://make.wordpress.org/support/handbook/getting-started/getting-started-at-a-contributor-day/., @nacin and a few other folks investigated methods for automating this process, but found that it wasn’t a viable option.

Instead, the fastest option is going to be a manual merge. I’ve created a spreadsheet with a list of all of the changes in the 5.0 branch, and the files they touched.

With a couple of workflow considerations, we can use this spreadsheet to avoid getting in each others way, and duplicating work:

  1. Assign yourself a commit that you’re working on merging. If there are multiple related commits that you’re going to work on, assign them all at the same time.
  2. There’s no need to commit every changeset individually, particularly those that will be overwritten by a later commit. For example, package.json or .travis.yml changes. Mark the earlier commits as Skipped.
  3. If you mark a changeset as Blocked or Skipped, leave a note with the reason.

Here are a few reminders while you’re running through changes:

  • Please read the Backporting Commits handbook page on best practices. If the svn merge command doesn’t apply cleanly, and you need to manually merge the commit, you can use the --record-only switch to record the merge, but not apply the changeset.
  • trunk is enforcing coding standards, so it’s a good idea to run composer install when you switch to trunk, then composer run format on the files you’re about to commit. grunt precommit will automatically do this.
  • Remember to add relevant information to the commit message:
    • “Merges [12345] from the 5.0 branch to 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..”
    • Copy all props from the original commit.
    • “Fixes #54321“, so the relevant ticketticket Created for both bug reports and feature development on the bug tracker. is auto-closed.

Finally, here is the status of the branches:

4.9 branch

The 4.9 branch is in normal status. As the previous major releasemajor release A release, identified by the first two numbers (3.6), which is the focus of a full release cycle and feature development. WordPress uses decimaling count for major release versions, so 2.8, 2.9, 3.0, and 3.1 are sequential and comparable in scope., changes are only back ported on a case-by-base basis. There’s nothing to be merged from the 5.0 branch to the 4.9 branch.

5.0 branch

The 5.0 branch is closed until the work on porting changes to trunk is complete, at which point it returns to normal status. If the porting takes more than a few days, it may be returned to normal status for the purposes of releasing a 5.0.1 betaBeta A pre-release of software that is given out to a large group of users to trial under real conditions.

JavaScript Packages and Interoperability in 5.0 and Beyond

WordPress 5.0 adds a number of new bundled script handles, including many specific to the new editor, as well as a few vendor dependencies. Given that a 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 WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party or theme may already have registered their own copies of these same dependencies, this post is meant to serve as a reference for maximum interoperability. These are tips which could apply for any new dependency added by WordPress in any version, but are more likely than usual to be encountered given the amount of new JavaScriptJavaScript JavaScript or JS is an object-oriented computer programming language commonly used to create interactive effects within web browsers. WordPress makes extensive use of JS for a better user experience. While PHP is executed on the server, JS executes within a user’s browser. https://www.javascript.com/. included starting in 5.0.

WordPress-Specific Scripts

All new WordPress-specific JavaScript code is registered using wp- as a prefix for the script handle. These include the following script handles:

  • wp-a11y
  • wp-annotations
  • wp-api-fetch
  • wp-autop
  • wp-blob
  • wp-block-library
  • wp-block-serialization-default-parser
  • wp-blocks
  • wp-components
  • wp-compose
  • wp-core-data
  • wp-data
  • wp-date
  • wp-deprecated
  • wp-dom-ready
  • wp-dom
  • wp-edit-post
  • wp-editor
  • wp-element
  • wp-escape-html
  • wp-format-library
  • wp-hooks
  • wp-html-entities
  • wp-i18n
  • wp-is-shallow-equal
  • wp-keycodes
  • wp-list-reusable-blocks
  • wp-notices
  • wp-nux
  • wp-plugins
  • wp-polyfill-element-closest
  • wp-polyfill-fetch
  • wp-polyfill-formdata
  • wp-polyfill-node-contains
  • wp-polyfill
  • wp-redux-routine
  • wp-rich-text
  • wp-shortcode
  • wp-token-list
  • wp-url
  • wp-viewport
  • wp-wordcount

Documentation for these packages can be found in the Gutenberg Handbook. They are also available for consumption via npm under the @wordpress scope (excluding polyfills).

Each WordPress package above assigns itself to the global scope under the wp namespace. For example, if your theme or plugin enqueues wp-editor, it will be made available at window.wp.editor in your browser. Conversely, you should also make sure that, for any JavaScript in your plugin which references a wp-namespaced library, the associated script handle is defined as a dependency of your script using the third argument of wp_enqueue_script and wp_register_script.

Vendor Dependencies

The following vendor dependencies have been added in WordPress 5.0:

For vendor scripts in particular, there is a chance for conflictconflict A conflict occurs when a patch changes code that was modified after the patch was created. These patches are considered stale, and will require a refresh of the changes before it can be applied, or the conflicts will need to be resolved. if a plugin or theme registers their own copy of the dependency with the same un-prefixed name. There is a greater likelihood if there is a large version mismatch between the registered scripts.

In general, a plugin should seek to avoid naming collisions by following the best practice of “Prefix Everything” as prescribed in the Plugin Handbook. While this can sometimes result in multiple copies of a script being present in a page, it reduces the chance for breakage and grants WordPress the option to use the unprefixed name in the future.

For dependencies which assign themselves to the global window scope, wp_add_inline_script can be used to ensure it is assigned to a global name unique to your plugin or theme. For example, the following snippet demonstrates including ReactReact React is a JavaScript library that makes it easy to reason about, construct, and maintain stateless and stateful user interfaces. https://reactjs.org/. on a page for a plugin without interfering with a coreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress.-enqueued copy of React, whether or not it exists:

wp_enqueue_script( 'myplugin-react', 'https://unpkg.com/react@16.6.0/umd/react.production.min.js' );
wp_add_inline_script( 'myplugin-react', 'window._originalReact = window.React;', 'before' );
wp_add_inline_script( 'myplugin-react', 'window.mypluginReact = window.React; window.React = window._originalReact;' );

With the above snippet, your intended copy of React will be guaranteed to be available at window.mypluginReact . This pattern can be applied to any vendor dependency to ensure compatibility with libraries added to WordPress in the future.

If your plugin or theme registers a script with using one of the above script handles as its registered name, consider taking one of the following steps:

Depending on whether you plan to continue support for versions of WordPress earlier than 5.0…

  • If you are only intending to target 5.0 and newer, verify compatibility between the versions of the library and simply remove your plugin or theme’s registration of the conflicting script handle.
  • If earlier version support is needed, and assuming your script registration occurs after the default scripts are registered (after wp_default_scripts), check for whether the script handle is already registered , then register or enqueue your copy of the script, optionally deregistering the core-registered script. Note that since core code targets a specific version of the vendor dependency, deregistering the script may have adverse effects on screens where it is used (notably the new editor screen).
    • Alternatively, follow the pattern as described above to assign your plugin’s copy of the library to a unique name.

Lodash Global

By default, Lodash will assign itself on the global scope using the _ name. Since WordPress will continue to bundle Underscore for the foreseeable future (see #43733), the core-registered Lodash adopts an approach similar to the enqueuing of jQuery to avoid naming conflicts. It does so using Lodash’s _.noConflict, assigning Lodash to the global scope as window.lodash. 

For this reason, if your plugin or theme uses Lodash as a dependency, you should make sure to not cause _.noConflict to be called multiple times in conflict with the core-registered script.

  • When using the copy of Lodash registered by core, your code should reference it by the window.lodash global.
  • When enqueuing your own copy of Lodash, you should only call Lodash’s _.noConflict under the condition that window.lodash is not already assigned and that the core-registered Lodash will not be included on the page.

In general, the _ global should be used only to reference Underscore.

React and wp-element

When extending the new editor interface, you should use the new wp-element script handle, rather than React directly. The element package is a thin abstraction over the React interface, and implements most all of the same functionality. Targeting wp-element will ensure the greatest compatibility for your plugin as new versions of WordPress are released.

Refer to the wp-element package documentation and React website for more information.

The revision system allows you to see what changes were made in each revision by dragging a slider (or using the Next/Previous buttons). The display indicates what has changed in each revision., was an intentional design decision because all post types need the ability to autosave whether or not revisions are enabled.

Only id, title, post_content and excerpt are saved on this endpoint, but a full, updated post object is returned in the response. It also returns the preview_link, which drives the Post Preview button in the new editor. 

Note: This endpoint requires requests to be authenticated.

Ticketticket Created for both bug reports and feature development on the bug tracker. #43316

Search

In order to facilitate searching across multiple post types, a new WP_REST_Search_Controller class was added which registers a /wp/v2/search endpoint. This endpoint is used by the link inserter in the new editor. 

Search types are handled by extending WP_REST_Search_Handler. The default search type is WP_REST_Post_Search_Handler, but this can be filtered by plugins or a theme by using the wp_rest_search_handlers filter.

Ticket #39965

Block Type

A new hidden post type of wp_block has been added for storing reusable blocks. Information about the post type is available at wp/v2/types/wp_block, including the labels and the capabilitiescapability A capability is permission to perform one or more types of task. Checking if a user has a capability is performed by the current_user_can function. Each user of a WordPress site might have some permissions but not others, depending on their role. For example, users who have the Author role usually have permission to edit their own posts (the “edit_posts” capability), but not permission to edit other users’ posts (the “edit_others_posts” capability). required in order to read and create reusable blocks.

Ticket #45098

Blocks

The individual reusable blocks can be retrieved from wp/v2/blocks. This uses the standard post controller to return post objects containing the rendered content and associated data of each reusable block. 

Note: This endpoint requires requests to be authenticated.

Ticket #45098

Block Renderer

All dynamic blocks with server-side rendering, such as the latest comments or archives, can be accessed at wp/v2/block-renderer/<name>. Names have to be structured as namespace/block-name, where namespace is the name of your 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 WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party or theme. An example core endpoint would be wp/v2/block-renderer/core/archives.

All registered attributes for the block being rendered are accepted as GET parameters. These are validated against the schema matching what was declared in register_block_type().

Note: This endpoint requires requests to be authenticated.

Ticket #45098

Themes

A minimal wp/v2/themes themes endpoint has been introduced to inform the new block-based editor of the features that the active theme supports. This allows the correct panels, features, and UIUI User interface elements to be shown or hidden for the user.

This will currently only return data about the active theme. This endpoint must also be accompanied by the status parameter with a value of active. For example: wp/v2/themes?status=active

The current data included in the response is:

  • A list of post formats supported.
  • Post thumbnail support details.
  • Whether responsive embeds are supported.

In the future the themes endpoint can be expanded, but this was the minimum required information for the new block editor to have all the data it needs to work correctly.

Note: This endpoint requires requests to be authenticated.

Ticket #45016

Additional Changes of Note

In addition to the new endpoints, there are a number of changes to REST API responses developers should be aware of.

  • All custom taxonomies must have show_in_rest set to true in order to appear in the new editor.
  • A new function wp_is_json_request() has been added to determine if the request is expecting a JSONJSON JSON, or JavaScript Object Notation, is a minimal, readable format for structuring data. It is used primarily to transmit data between a server and web application, as an alternative to XML. response, and if so, silence PHPPHP The web scripting language in which WordPress is primarily architected. WordPress requires PHP 7.4 or higher warnings and errors. [43730]
  • In order for clients to present permalink previews, the REST API must share the computed results of get_sample_permalink(). These values are now exposed as permalink_template and generated_slug for public, viewable post types, but only for context=edit. [43720]
  • Any fields registered with register_rest_field() now respect the ?_fields= filter parameter in the request URLURL A specific web address of a website or web page on the Internet, such as a website’s URL www.wordpress.org. [43736]
  • Users with read_private_posts capabilitycapability A capability is permission to perform one or more types of task. Checking if a user has a capability is performed by the current_user_can function. Each user of a WordPress site might have some permissions but not others, depending on their role. For example, users who have the Author role usually have permission to edit their own posts (the “edit_posts” capability), but not permission to edit other users’ posts (the “edit_others_posts” capability). can now query for private posts on the posts endpoint. [43694]
  • The unfiltered_html capability is now declared using JSON Hyper Schema targetSchema. [43682]
  • A block_version value is added to the post object to denote whether post contains blocks and of what version. At this point there is only one version, but if the block format has backwards compatibility breaking changes in the future, we can increment this value as needed. [43770]
  • New rest_after_* action hooks have been added that fire after all write operations have completed. [42864]

Media 5.0 Guide

The 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. editor in WordPress 5.0 brings a much needed refresh to how we interact with media in the editor. 5.0 has provided new features designed to make complex content easier to create, and is built in a way that is now truly “what you see is what you getWhat You See Is What You Get What You See Is What You Get. Most commonly used in relation to editors, where changes made in edit mode reflect exactly as they will translate to the published page.”! There are some big changes to where things are, new methods of accessing `classic` functionality, as well as new features you may not even know about. Let’s highlight a few of those!

Where is the add media button?

If you are looking for the add media button for any reason, this can be found in the classic block TinyMCE toolbar labeled “add media”. This button will trigger the media modal.

Gallery Block:

We have improved the Gallery experience with a new block that gives users a truly real time interactive Gallery.

If you need to utilize dynamic galleries that are based on post ID, or if you need to use the `post_gallery` filterFilter Filters are one of the two types of Hooks https://codex.wordpress.org/Plugin_API/Hooks. They provide a way for functions to modify data of other functions. They are the counterpart to Actions. Unlike Actions, filters are meant to work in an isolated manner, and should never have side effects such as affecting global variables and output., this can still be achieved using the `add media` button located in the classic block TinyMCE toolbar.

Wide Alignment Theme Support:

Some blocks, such as the image block, have the ability to define a “wide” or “full” alignment in the new editor. This is accomplished by adding the `.alignwide` or `.alignfull` classes, respectively, to the image’s wrapper element. A theme can opt-in for this feature by calling: 

add_theme_support( 'align-wide' );

For more information on Wide Alignment, or if you would like to explore the potential markup of images in this context, the documentation has more details.

WordPress 5.0 Release Day!

Welcome to the WordPress 5.0 release day, everyone! It’s currently a chilly -2°C here in Nashville, we’re going to keep everyone toasty and warm with a shiny WordPress release, and a new jazz artist to dance along to!

The current plan is to start the release process at December 6th, 2018 at 17:00 UTC, in the #core channel in the Making WordPress SlackSlack Slack is a Collaborative Group Chat Platform https://slack.com/. The WordPress community has its own Slack Channel at https://make.wordpress.org/chat/..

The major version release process can take a bit more time than the betas or RCs did, particularly if we run into any last minute issues that need to be addressed.

The Release Process

We’ll be working through the Major Version Release process, for anyone who wants to follow along.

I ran through the Dry Run steps last night, there were no changes needed.

Where the documentation refers to “report 40”, we’ll instead be using this Trac query, which looks at tickets reported against 5.0, rather than `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.`.

How You Can Help

A key part of the release process is checking that the zip packages work on all the different server configurations available. If you have some of the less commonly used servers available for testing (IIS, in particular), that’d be super helpful. Servers running older versions of PHPPHP The web scripting language in which WordPress is primarily architected. WordPress requires PHP 7.4 or higher and MySQLMySQL MySQL is a relational database management system. A database is a structured collection of data where content, configuration and other options are stored. https://www.mysql.com/. will also need testing.

You can even start this early, by running the WordPress 5.0 RC3 packages, which are built using the same method as the final packages will be.
