Pressbooks 5: Developer Guide

Pressbooks 5 will introduce some significant changes to the ways we store and retrieve data within the book, a new export module, modifications to two existing export modules, and some changes to the filesystem for user generated content. This post outlines these key changes and the migration paths that we’ve built in to facilitate the upgrade to Pressbooks 5.

Data Changes

Content Visibility

In Pressbooks 4.x and earlier, the visibility of content across different media is controlled by a combination of custom post metadata and core post status. For front matter, back matter and chapters, the pb_export post meta value determines whether or not they appear in exports, while their post status (draft, pending, private, or publish) determines their visibility in the webbook.

In an effort to better conform to WordPress best practices and streamline the user experience, we’re using the post status as the source of truth for whether front matter, chapters, and back matter appear in web, exports, or both. We’ve added a new web-only post status, and content visibility will now be determined as follows:

Post Status Web + REST API Exports
draft hidden hidden
web-only visible hidden
private hidden visible
publish visible visible

In terms of the user interface, we’re changing this:

A mockup of the Export Settings & Publish panels in Pressbooks 4.x.

To this:

A mockup of the Status & Visibility panel for a new chapter in Pressbooks 5. A mockup of the "Status & Visibility" panel for an existing chapter in Pressbooks 5.

Note that we’re changing the primary action button from "Publish" for new content and "Update" for existing content to "Create" and "Save", respectively.

Your front matter, back matter and chapters will be automatically updated when you visit your book after updating to Pressbooks 5.

Contributor Management

Pressbooks 4.x lets you add a single author and multiple contributing authors, editors, and translators in your Book Information and lets you add a single author for each front matter, back matter, or chapter. Pressbooks 5 imports all your existing authors (and Pressbooks users who are assigned to your book) and creates entries in a new contributor taxonomy. Then, it repopulates new relevant metadata fields with a list of contributors that match your book’s existing contributors. For example, if you have an author named Alice X and two editors named Bob Y and Eve Z, your Book Information will contain the following in Pressbooks 4.x:

Field Value
pb_author 'Alice X'
pb_editor ['Bob Y', 'Eve Z']

In Pressbooks 5, your Book Information will contain the following:

Field Value
pb_authors 'alice-x'
pb_editors ['bob-y', 'eve-z']

The values saved in Book Information are the slugs of entries in the contributor taxonomy. Also, for backwards-compatibility, the new field names are pluralized so that any third-party code that looks for the old fields will still be able to retrieve them for the time being.

You’ll be able to edit the display names of these contributors in one place — the new Contributors page, which is a standard WordPress taxonomy management page — and you’ll be able to quickly and easily select from your list of contributors to add assign authors throughout your book (if you have a book that consists of chapters with different authors, and you also want to include credits for all the authors in your Book Information, this will make maintaining that information much easier). In future releases of Pressbooks, we will be able to add metadata to contributors, including profile pictures, author websites, and more, for display on your webbook cover page or individual front matter, back matter, and chapters.

We’re also adding a new class, \Pressbooks\Contributors\, and some other related functions to retrieve arrays or formatted lists of contributors.

The migration of your book’s contributor data will happen automatically when you visit your book after updating to Pressbooks 5.


In the same way that we’re moving contributor data to a contributor taxonomy, we’re moving the available licenses into a new license taxonomy. That way, if you need to add a custom license for your book, it will immediately be available in all chapters, front matter, and back matter as well as your Book Information. This migration will happen automatically when you visit your book after updating.

Export Changes

HTMLBook Preview

In Pressbooks 5, we’ve introduced a new HTMLBook export module as a proof of concept. We’re excited about the potential of adopting and advancing this proposed standard for the semantic representation of books on the web, and we will be actively developing our export module in the months to come. We’re also working with the creators of HTMLBook to expand and improve the standard (to begin with, we’re proposing the addition of new front matter and back matter types and of new block elements, including educational textboxes).

At this time, our HTMLBook exporter is not production-ready, but we will be using it as a testbed to refine our best practices for coding export modules in Pressbooks.

XHTML and EPUB Markup Changes

We’re making a change to the way we mark up our XHTML and EPUB exports, but only for themes that use our SCSS component library, Buckram. In Pressbooks 4.x, chapter subtitle and author elements are not wrapped in the same container as the chapter number and title:

<div class="chapter standard" id="chapter-1">

  <div class="chapter-title-wrap">

    <h3 class="chapter-number">1</h3>

    <h2 class="chapter-title">Loomings</h2>


  <div class="ugc chapter-ugc">

    <h2 class="chapter-author">Herman Melville</h2>

    <h2 class="chapter-subtitle">The First Chapter</h2>

    <p>Call me Ishmael.</p>



This makes it very difficult to reliably style the first page of front matter, back matter, and chapters.

In Pressbooks 5, books that use Buckram-based themes will now have the following markup:

<div class="chapter standard" id="chapter-1">

  <div class="chapter-title-wrap">

    <h3 class="chapter-number">1</h3>

    <h2 class="chapter-title">Loomings</h2>

    <h2 class="chapter-author">Herman Melville</h2>

    <h2 class="chapter-subtitle">The First Chapter</h2>


  <div class="ugc chapter-ugc">

    <p>Call me Ishmael.</p>



This change will only impact themes using Buckram, which include our open source Clarke theme and the premium Asimov theme (the latter only available to Pressbooks EDU or users). We are thoroughly testing these Buckram-based themes to ensure that this change does not affect existing books. If you have built a theme using Buckram, we suggest you test your theme as well once this issue has been closed.

Filesystem Changes

In Pressbooks 4.x, all export files, (S)CSS and other user-generated files are stored in subfolders of your book’s uploads directory. We’re moving them all into a pressbooks folder to prevent conflicts between our files and any other files that plugins may generate. This will happen without the need for any intervention on your part.

Moving Half a Million Database Tables to AWS Aurora (Part 2)

Quick recap: Migrate half a million database tables from a single bare metal server with 1 database to 101 database slices on AWS Aurora.

Wait, half a million database tables?! Answered in Part 1.


  1. Stop the server, take an LVM snapshot.
  2. Use mydumper to dump the snapshot to SQL files.
  3. rysnc these to the new server.
  4. Use myloader to load the SQL files into the new databases.

Captain Not So Obvious

Why not setup the Aurora as a replica and then switch over?

Because our MariaDB server was a bare metal box outside of AWS. The read Replica docs imply that MySQL has to already be in AWS for that to work. If that’s not enough this doc says use mysqldump to start, then sync after. This doc also says use mysqldump. All signs point to nope.

Why not DMS?

Answered in Part 1.

Mostly, at the end of the day, because our hosted networks are already on AWS it was simply more cost effective to shut down our freemium site and migrate in one swoop than to have our whole team keep at this for weeks, possibly months.

Epilogue: What About Uploads?

Each book has media library files (GIF, PNG, JPG, EPUB, PDF, etc). A few days before the migration, we copied all files from the production server’s uploads/ directory using rsync:

rsync -avz -e "ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null" someuser@oldpressbooksdotcom:/path/to/uploads/ /path/to/uploads/ --progress

This process took about 10 hours.

Then, on migration day, we ran the same command again with the --delete option to update the new server with the latest files from the old server and remove any files that have been deleted on the old server:

rsync -avz --delete -e "ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null" someuser@oldpressbooksdotcom:/path/to/uploads/ /path/to/uploads/ --progress

Much quicker! (around 7 minutes)

Launch it!

“If we get into the trees it could be rather disastrous, so we’ve got to hit the roses.” – Ken Carter

Scripts from Part 1 (read it already!) were modified to include Slack notifications:

notify() {
  read -d '' payLoad << EOF
    "channel": "#operations",
    "username": "Pressbot",
    "icon_emoji": ":closed_book:",
    "text": "Slice \`${1}\` has been imported on AWS."

  curl \
    --write-out %{http_code} \
    --silent \
    --output /dev/null \
    -X POST \
    -H 'Content-type: application/json' \
    --data "${payLoad}" "<SLACK_WEBHOOK_ID>"

# Usage

notify $slice

In an effort to reduce downtime we imported slices as soon as they were transferred. Dumping was faster than imports.


Ned working hard:


All while coding sprint tasks in between.

Things That Went Wrong

We noticed an embarrassing typo in the first few database slices we imported. We had to redo them because renaming a database with tens of thousands of tables in it is not obvious.

I ordered takeout from the wrong fish & chips shop. I had to take a subway 30 minutes to downtown to get it. (Psst Foodora, your geolocation feature sucks!)

Otherwise, nothing. We landed in the roses.


  • 8:00: Migration started.
  • 10:40: Database migration started.
  • 19:10: Database migration completed!
  • 19:30: Migration completed.
  • Total time: 11 hours 30 minutes.

DONE. Exciting to turn the page on this. Thanks for reading.

NOTICE: Users of the Pressbooks Custom CSS theme must upgrade to Pressbooks Custom CSS 1.0 for compatibility with Pressbooks >= 4.3.0.

  • [CORE ENHANCEMENT] Use Laravel Container instead of Pimple as our service container; add Laravel Blade support for future templated outputs (see #831, #962, and #970).
  • [FIX] Content imported from EPUB is now ordered by spine order instead of manifest order (props to @hakkim-pits; see #442 and #968).
  • [FIX] Custom styles are no longer sanitized in ways that improperly encode characters (see #972).
  • [FIX] Sanitize body font size PDF theme option as a float instead of an integer to allow more size options (see #969).
  • [FIX] home_url is now used instead of site_url when linking to front-end content (see #971; reference: roots/bedrock#316).
  • [FIX] Shortcodes will now be cloned as is to preserve more footnote and LaTeX data (see #973).
  • [FIX] Special characters in a book title will no longer lead to filename issues under certain circumstances (see #974).

Pressbooks Book 1.10.15

  • [FIX] Added cache busting to ensure that custom styles are loaded after save (see #46).

Moving Half a Million Database Tables to AWS Aurora (Part 1)

This post is about migrating to AWS.

Does It Scale?

At Pressbooks we use WordPress Multisite as a development platform. Pressbooks changes WordPress and makes every blog a book.

The prevailing wisdom of the day is that a relational database should have a manageable set of tables with lots of rows of data in them …and then there’s WordPress.

WP Multisite creates 10 database tables for every blog (or in our case: for every book.) Tables share IDs but they are not enforced at the database level. There are no foreign key constraints, no triggers, nor routines. It’s simple no frills MySQL.

Pressbooks dot com is currently running on a single bare metal server. (Our hosted instances are already on AWS) This server has a single MariaDB database with 60,000 books in it. When we do the math that’s over 600,000 tables in one database. Are you nuts?! Unusual? Horrible? Yet entirely possible, even plausible.

I’ve met people who worked at Automattic and from the stories, I heard WordPress dot com uses the same WP Multisite technology but instead of half a million tables it’s over a billion tables (probably not all in the same database though, more on that later).

I call this the Schrödinger’s Cat of database design because so long as we don’t look it’s alive?


As I said, we already host hundreds of WP Multisite networks on AWS. We build, manage, and deploy to our infrastructure using Terraform, Ansible, wp-cli and all things competent. We simply just, sort of, well, neglected to move our freemium site over because we were too busy.

The time has come.


We tried mysqldump. It was too slow. Our tests showed that a dump would take days.

Some colleagues recommended AWS DMS. It did not work.  Some reasons:

  • The AUTO_INCREMENT attribute is not migrated.
  • WP Multisite tables are prefixed wp_1_, wp_2_, wp_3_, ... MySQL considers the underscore a one character wildcard when used in LIKE queries, DMS provided no way to escape it for table filters.
  • Unexplained crashing on anything less than a c4.large (failed last Error The task stopped abnormally Stop Reason RECOVERABLE_ERROR Error Level RECOVERABLE)
  • Mostly, the fastest migration we could get going, running 4 tasks in parallel, was an ETA of 10 days

We asked for help. Ned had a conference call with a reputable consulting firm and they gave us a quote: $34K USD + travel & on-site expenses.

Coffee spitting

Next, our research led us to mydumper. From the README:

== What is mydumper? Why? ==

  • Parallelism (hence, speed) and performance (avoids expensive character set conversion routines, efficient code overall)
  • Easier to manage output (separate files for tables, dump metadata, etc, easy to view/parse data)
  • Consistency – maintains snapshot across all threads, provides accurate master and slave log positions, etc
  • Manageability – supports PCRE for specifying database and tables inclusions and exclusions

So far so good…

== How to build it? ==

Jerry Seinfeld leaving

Just kidding. It turns out we don’t have to build mydumper. On Ubuntu sudo apt install mydumper works fine. Similar command using yum on CentOS.

Our tests conclude that mydumper finishes in hours instead of days.


It is our opinion that this kind of problem is better suited for a document-oriented database. Given that this is the database design we inherited, there’s not much we can do about it, so we’ll try our best with what we’ve got. ¯_(ツ)_/¯

At a billion tables, Automattic has already established its own internal best practices with plugins like HypderDB. Unfortunately HyperDB doesn’t have Composer support and doesn’t look maintained. LudicrousDB, a Composer compatible drop-in that works with our existing tech stack, to the rescue.

LudicrousDB is an advanced database interface for WordPress that supports replication, fail-over, load balancing, and partitioning, based on Automattic’s HyperDB drop-in.

With LudicrousDB tested and working, we are moving towards a 101 slice approach. 1 slice for core tables and 100 slices for books.

The idea is to use the last two digits of a book ID to pick one of 100 slices. If this becomes unmanageable in the future (important to remember that we already have over half a million tables in 1 database and things are fine), we can change the splitting algorithm by adding a condition to use the last X digits on books with IDs bigger than Y.


For informational purposes only. Read the snippets and reason about them. Copy/paste at your own peril.

LudicrousDB  Callback

 * Slices
 * We can predict what slice a blog is in by looking 
 * at the last two digits of the id. Examples:
 * + blog_id: 9, in db09
 * + blog_id: 74, in db74
 * + blog_id: 999989, in db89
 * + blog_id: 9200, in db00
 * @param $query
 * @param \LudicrousDB $wpdb
 * @return string
function pb_db_callback( $query, $wpdb ) {
  if ( preg_match( "/^{$wpdb->base_prefix}\d+_/i", $wpdb->table ) ) {
    $last_two_digits = (int) substr( $wpdb->blogid, -2 );
    $db = sprintf( 'db%02d', $last_two_digits ); // db00, db01, db02, ..., db99
    return $db;
  } else {
    return 'global';
$wpdb->add_callback( 'pb_db_callback' );

Export DB Into 101 Slices:


# This script will CREATE 101 directories in current 
# working directory, you have been warned!


sudo mydumper --regex="^${db}\.wp_[a-zA-Z]+.*" --database="${db}" --outputdir="core" --build-empty-files
for ((i=0; i<=99; i++)); do
  ii=`printf %02d $i`
  sudo mydumper --regex="^${db}\.(wp_${i}_|wp_\d+${ii}_).*" --database="${db}" --outputdir="${ii}" --build-empty-files

Import 101 Slices:


# This script will READ 101 directories in current 
# working directory


sudo myloader --directory="core" --database="${db}" --overwrite-tables
for ((i=0; i<=99; i++)); do
  ii=`printf %02d $i`
  sudo myloader --directory="${ii}" --database="${db}_${ii}" --overwrite-tables

Did it work?

To be continued in Part 2…

Bonus tips:

Because Pressbooks has so many MySQL tables, the Clients I use are always getting stuck or freezing. Here are some tricks I use to keep sane:

  • Don’t let MySQL Workbench load the table schemas. Set up your GUI so that schemas are in a separate tab, disable autoloading, autocomplete, etc. (Edit ⇨ Preferences ⇨ SQL Editor)
  • Disable MySQL CLI auto-completion with --disable-auto-rehash

Our new roadmap

At the start of 2017, we established a development roadmap for Pressbooks to guide our work through the coming year. This past week we had the opportunity to review and reflect on that roadmap during our retreat at Pressbooks HQ, and you can see our new roadmap here.

2017: Year of Core

I want to highlight a few of our accomplishments from the past nine months (you’ll see them crossed out on the old roadmap). In retrospect, our clear focus over the past nine months was improving Pressbooks’ core technology. When Dac came back, having a second developer let us expand upon my efforts in recent years to standardize our development processes under the hood. We now use consistent coding standards across all of our open source projects, and we have adopted a standardized build process for admin and front end assets. We have expanded our code coverage on the core Pressbooks plugin, and continue to do so with every release. These improvements let us work more efficiently and give open source contributors a clear framework within which to contribute to the Pressbooks ecosystem.

Our most significant core enhancement is our new REST API, built on the WordPress Core REST API infrastructure. This is the engine that powers our new cloning tool, and we will be making use of it in other areas over the next year. We’re also extremely excited to see what the Pressbooks Open Source community does with an API for books. If you are building something with it, let us know.

2018: Year of the Author

The roadmap for our next year has a new focus: improving Pressbooks for authors. There are a number of editing features that we included on our last roadmap that didn’t make the cut, and our goal for the next year is to fill as many of these gaps in the Pressbooks authoring toolset as we can. This includes:

  • Broadening our support for math, interactive content, video and audio across all formats (with graceful fallbacks in static formats like PDF)
  • Adding support for multiple contributors: authors, editors, translators and more
  • Adding indexing and glossary support

And more! Take a look at our new roadmap to see our comprehensive plans for improving Pressbooks’ authorship and editing tools, as well as all other aspects of the project.

I’m very excited about our accomplishments since January 2017, and I’m looking forward to building on them over the next year. Thanks to Apurva, Dac, Hugh, Liz, and Zoe for making Pressbooks such a productive team!
