Valuebound: Componentizing Drupal Front End using Pattern Lab

Vie, 03/09/2018 - 11:33

Componentization has become a growing consideration in most of the web application development firms. The reasons are obvious, instead of reinventing the wheels again and again, why don’t we re-use them. This article will help you to understand the importance of componentizing your Drupal front end and how you can achieve that using Pattern Lab.

So what is Componentization?

In front-end perspective, components are a collection of HTML, CSS, and JS that combines together to form a display element and Component-Driven Development (CDD), a development methodology by which the web pages are built from the bottom up. 'Componentization' is the process of breaking things down into small and easily…

Roman Agabekov: Mysql Master-Slave Replication

Vie, 03/09/2018 - 02:31
Mysql Master-Slave Replication Submitted by admin on Fri, 03/09/2018 - 04:31

Hey all! Today, we shall show you some examples of master-slave replication setups.

A bit of theory first

Why do you need replication in the first place? There are at least two reasons to set it up. First off, it is your insurance that helps avoid downtime when/if your master MySQL server goes down: with replication, slave server picks up and fills for the master. Secondly, replication allows decreasing load suffered by the master server: you use it for writing only and pass read queries to slave.

CU Boulder - Webcentral: Drupal Deep Dives: Ignoring Your Slaves

Jue, 03/08/2018 - 20:40

If you’re like me, you don’t know much about Drupal 7’s database layer besides a few functions you need to use daily. After scanning the comments for those API pages, I can usually get done what I need to, and I’ve never really have any weird database errors or issues that made me look more closely into the database APIs.

db_insert(); db_query(); db_merge(); // etc...

I work at an organization now that runs a service for 800+ sites with thousands of content editors. On any given day, the service performs more reads and writes than any application I’ve ever worked on before. Even with that caveat, our service doesn’t make all that many writes to the databases each day. However, our database infrastructure is set up (poorly) by another IT group (whose name shall not be mentioned), and because of that, we had to recently program defensively while performing database transactions.

Drupal Database API

Drupal has a nice overview page of documentation about how a developer ought to use the database APIs. Included in that section are topics I’ve never really explored.

For example, I’ve felt the pain of using Views as a query builder only to find out how slow and inefficient the default queries tend to be. Granted it is meant as a visual tool for site builders who can’t or don’t know how to use the database API functions, but it makes me sad sometimes.

Could I potentially use SQL Views to create some virtual tables and simplify my queries partially avoiding Drupal’s “join all the field tables together” issue? Probably, now that I know about SQL Views.

I won’t go over a lot of the functionality covered in the docs, but it’s not a bad idea to read through all of that API documentation if you never have before. That’s what Friday afternoons are for, right? Your Drupal application performs a lot of queries every request/response cycle, and by finding optimizations in these docs, you may drastically increase your app’s performance with only a few lines of code.

Master/Slave? Sounds Kinky

In the title of this post, I mentioned “slaves” mainly for the clickbait factor, but what I meant was in the context of a “master/slave” database relationship. Now people, put down the stones you are about to throw at me for my use of the word “slave” in 2018. In Drupal 7, that is the terminology used in the codebase, although in Drupal 8, it has been updated to “primary/replica” which is more semantic and descriptive. You can read a detailed discussion on the topic within the Drupal community, but I will still use “master/slave” at points in this post since Drupal 7 makes me use it.

Your site might only have one database, and for local development, my sites generally only have one database. The default.settings.php file shipped in Drupal 7 has a lengthy section on database configurations and what options are available to you.

For each database, you may optionally specify multiple "target" databases. A target database allows Drupal to try to send certain queries to a different database if it can but fall back to the default connection if not. That is useful for master/slave replication, as Drupal may try to connect to a slave server when appropriate and if one is not available will simply fall back to the single master server. The general format for the $databases array is as follows: @code $databases['default']['default'] = $info_array; $databases['default']['slave'][] = $info_array; $databases['default']['slave'][] = $info_array; $databases['extra']['default'] = $info_array; @endcode In the above example, $info_array is an array of settings described above. The first line sets a "default" database that has one master database (the second level default). The second and third lines create an array of potential slave databases. Drupal will select one at random for a given request as needed. The fourth line creates a new database with a name of "extra".

That segment of comments might be the only place you’ve seen “slave” mentioned in Drupal before. Normally, you’ve probably only used the “default” database info $databases['default']['default'] = $info_array; to set up a site. That’s all I was accustomed to using.

The “slave” database acts as a “replica” of the “master” or “default” or better yet “primary” database…you might be noticing why using “master/slave” was a bad idea regardless of the generally negative connotation of the word “slave”. It’s just not all that semantic when describing the responsibilities for each type of connection.

The “replica” database’s job is to sync with the default “primary” database so that there is only one canonical source of information. Replicas allow for failovers during times of high database load. Generally, reads are more important for the functionality of your application. Writes, on say saving a form, can always roll back transactions or provide feedback to a user on why the data can’t be saved. If an anonymous user goes to a page on your site and Drupal can’t read anything then everyone gets a fatal error.

If we go back to the comments above, you can see a “default” connection with one master and two slave databases. Drupal has some documentation on how that type of a database configuration works.

"This definition provides a single "default" server and two "slave" servers. Note that the "slave" key is an array. If any target is defined as an array of connection information, one of the defined servers will be selected at random for that target for each page request. That is, on one-page request, all slave queries will be sent to dbserver2 while on the next they may all be sent to dbserver3. This means that during any request one of the three default connections in that example might be used. On a site with high traffic, you can probably see how this database setup would come in handy for times of high load."

You can even tell Drupal to target one of the connections during a query.

$query = db_select('node', 'n', array('target' => 'slave')); Original DB Error

My initial foray into looking at master/slave replication in Drupal 7 came with a bug report.

PDOException: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '60-36' for key 'PRIMARY': INSERT INTO {linkchecker_bean} (bid, lid) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1); Array ( [:db_insert_placeholder_0] => 60 [:db_insert_placeholder_1] => 36 ) in _linkchecker_bean_add_bean_links() (line 196 of /data/code/profiles/express/express-2.8.3/modules/contrib/linkchecker/modules/linkchecker_bean/linkchecker_bean.module)

After some investigation, we thought that the slave database was being read before the sync from the master happened. When queried there was no entry in the slave database; however, the master database already had an entry. The master database always makes the writes and so a duplication error occurred during the next attempted insertion.

// Remove all links from the links array already in the database and only // add missing links to database. $missing_links = _linkchecker_bean_links_missing($bean->bid, $links); // Ignore slave database briefly. variable_set('maximum_replication_lag', 300); db_ignore_slave(); // Only add unique links to database that do not exist. $i = 0; foreach ($missing_links as $url) { $urlhash = drupal_hash_base64($url); $link = db_query('SELECT lid FROM {linkchecker_link} WHERE urlhash = :urlhash', array(':urlhash' => $urlhash))->fetchObject(); if (!$link) { $link = new stdClass(); $link->urlhash = $urlhash; $link->url = $url; $link->status = _linkchecker_link_check_status_filter($url); drupal_write_record('linkchecker_link', $link); } db_insert('linkchecker_bean') ->fields(array( 'bid' => $bean->bid, 'lid' => $link->lid, )) ->execute(); // ...

The original code makes a db query for $missing_links that must have gone to a replica database that hadn’t yet synced with the primary database. That is why later in the code when the db_insert() happens, the insert fails.


My first thought when I looked at the code was to use db_merge() instead of db_insert(). By using a merge query you either make an update or insertion query to the database table. By providing the same primary keys as the ones you are inserting, you can ensure that the database query never fatal errors due to duplicate content existing in the table.

db_merge('linkchecker_bean') ->key(array( 'bid' => $bean->bid, 'lid' => $link->lid, )) ->fields(array( 'bid' => $bean->bid, 'lid' => $link->lid, )) ->execute();

However, this “solution” doesn’t really address the issue. The code isn’t supposed to update a value that could already exist in the table. In this case, the correct thing is happening by giving me a fatal error. The problem is that the error isn’t caught.

Proper Exception Handling

You should always wrap any function call that might fail terribly in a try/catch statement. The try block of code acts just as it would without try {} wrapped around it. The catch block allows any potential error in the try block to be caught and dealt with without breaking execution of the PHP script.

$txn = db_transaction(); try { db_insert('linkchecker_bean') ->fields(array( 'bid' => $bean->bid, 'lid' => $link->lid, )) ->execute(); } catch (Exception $e) { $txn->rollback(); watchdog_exception('linkchecker_bean', $e); }

Now we have preserved the original db_insert()while catching the original fatal error. You’ll also notice that adb_transaction() object is used to rollback any transaction if the insert fails.

I never knew about that functionality in Drupal 7, but I have grown accustomed to being able to rollback database transactions in other PHP frameworks. Too bad most module developers don’t integrate a rollback on erroneous database transactions. Drupal core could be taking care of this under-the-hood, but I’d rather see it explicitly defined in contributed code. From now on, I’ll probably be using those functions in my hook_update() code. You can read more about database error handling in the Drupal database documentation.

I was pretty satisfied with submitting a patch the Linkchecker project based on the code above, except that it didn’t fix our issue. Since our theory revolved around database replication being slow, we had to go one step further and explicitly define the relationship between primary and replica database connections at the time of the missing link's query.

Finally, Ignore The Slaves

We finally get to do it, folks. Ignore those stupid slaves…and Twitter has gone wild again with hateful tweets directed at me…okay, okay, back to calling them replicas. You can tell Drupal to ignore the replica databases and only interact with the primary connection if you need to.

// Ignore slave database briefly. variable_set('maximum_replication_lag', 300); db_ignore_slave(); // Remove all links from the links array already in the database and only // add missing links to database. $missing_links = _linkchecker_bean_links_missing($bean->bid, $links); // Only add unique links to database that do not exist. $i = 0; foreach ($missing_links as $url) { $urlhash = drupal_hash_base64($url); $link = db_query('SELECT lid FROM {linkchecker_link} WHERE urlhash = :urlhash', array(':urlhash' => $urlhash))->fetchObject(); if (!$link) { $link = new stdClass(); $link->urlhash = $urlhash; $link->url = $url; $link->status = _linkchecker_link_check_status_filter($url); drupal_write_record('linkchecker_link', $link); } $txn = db_transaction(); try { db_insert('linkchecker_bean') ->fields(array( 'bid' => $bean->bid, 'lid' => $link->lid, )) ->execute(); } catch (Exception $e) { $txn->rollback(); watchdog_exception('linkchecker_bean', $e); } // Go back to using the slave database. // db_ignore_slave() sets this session variable that another function uses to see if the slave should be ignored. unset($_SESSION['ignore_slave_server']); // ...

Our final code ignores the replicas for a brief time using db_slave_ignore() and then returns querying back to normal by unsetting $_SESSION['ignore_slave_server'] after all of the database queries have run.

Internally, Drupal uses the session variable, which is a timestamp, to check whether the slave server should be ignored. This is done via hook_init() in the System module usingDatabase:ignoreTarget('default', 'slave'). There is also a nice note in the comments about how the ignoring works.

function system_init() { $path = drupal_get_path('module', 'system'); // Add the CSS for this module. These aren't in system.info, because they // need to be in the CSS_SYSTEM group rather than the CSS_DEFAULT group. drupal_add_css($path . '/system.base.css', array('group' => CSS_SYSTEM, 'every_page' => TRUE)); if (path_is_admin(current_path())) { drupal_add_css($path . '/system.admin.css', array('group' => CSS_SYSTEM)); } drupal_add_css($path . '/system.menus.css', array('group' => CSS_SYSTEM, 'every_page' => TRUE)); drupal_add_css($path . '/system.messages.css', array('group' => CSS_SYSTEM, 'every_page' => TRUE)); drupal_add_css($path . '/system.theme.css', array('group' => CSS_SYSTEM, 'every_page' => TRUE)); // Ignore slave database servers for this request. // // In Drupal's distributed database structure, new data is written to the // master and then propagated to the slave servers. This means there is a // lag between when data is written to the master and when it is available on // the slave. At these times, we will want to avoid using a slave server // temporarily. For example, if a user posts a new node then we want to // disable the slave server for that user temporarily to allow the slave // server to catch up. That way, that user will see their changes immediately // while for other users we still get the benefits of having a slave server, // just with slightly stale data. Code that wants to disable the slave // server should use the db_ignore_slave() function to set // $_SESSION['ignore_slave_server'] to the timestamp after which the slave // can be re-enabled. if (isset($_SESSION['ignore_slave_server'])) { if ($_SESSION['ignore_slave_server'] >= REQUEST_TIME) { Database::ignoreTarget('default', 'slave'); } else { unset($_SESSION['ignore_slave_server']); } } // Add CSS/JS files from module .info files. system_add_module_assets(); } Wait, We’ve Already Executed hook_init()?

Since it happens in a hook_init(), then pray-tell how is the database ignored later in my Linkchecker code? I’m not sure either. Subsequent requests will ignore the replica for as long as the timeout is active, but the queries in my code could possibly still hit the slave database. Wait, so I haven’t fixed my issue. And you certainly don’t want to place db_ignore_slave() before the hook_init() is called, essentially always setting a timeout to ignore the replica.

In the comment above the session variable check, it explains that some users will see stale data. This is okay for the scenario where I save content via a node edit screen and expect it to show up on the next node view request. But what happens when there is no “user” saving content and the queries happen within a request cycle, not write on one request and then read on another.

I am one of the “users” who can’t get stale data because we are relying on it to make a subsequent database insert in the same request. What we really need to do is “target” the default connection when we make a query.

db_query('SELECT lid FROM {linkchecker_link} WHERE urlhash = :urlhash', array(':urlhash' => $urlhash), array('target' => 'default'))->fetchObject();

Up until this point, I had only used the $args array to pass in dynamic variables to database queries and avoid SQL injection, but there is another $options parameter you can use to identify the database target among other things. While the allowed values for $options can be hard to know from the db_query() API documentation, you can at least find the default values created when that parameter isn’t passed into db_query(). Based on the docs for the “target” key, you can have two values for the target: “slave” or< “default”.

"The database "target" against which to execute a query. Valid values are "default" or "slave". The system will first try to open a connection to a database specified with the user-supplied key. If one is not available, it will silently fall back to the "default" target. If multiple databases connections are specified with the same target, one will be selected at random for the duration of the request. So when you don’t explicitly specify a target and have more than one connection, e.g. adding a replica, the query will pick a target at random which might be a slave with stale data."

After adding a target in another Linckchecker query, my job was done…and I didn’t even have to ignore the slaves after all. Hopefully, you now know something about database replication in Drupal 7, how to use db_ignore_slave() properly, and how to explicitly target databases per query as well.

Dries Buytaert: Thank you, Tiffany

Jue, 03/08/2018 - 18:17

I recently had the opportunity to read Tiffany Farriss' Drupal Association Retrospective. In addition to being the CEO of Palantir.net, Tiffany also served on the Drupal Association Board of Directors for nine years. In her retrospective post, Tiffany shares what the Drupal Association looked like when she joined the board in 2009, and how the Drupal Association continues to grow today.

What I really appreciate about Tiffany's retrospective is that it captures the evolution of the Drupal Association. It's easy to forget how far we've come. What started as a scrappy advisory board, with little to no funding, has matured into a nonprofit that can support and promote the mission of the Drupal project. While there is always work to be done, Tiffany's retrospective is a great testament of our community's progress.

I feel very lucky that the Drupal Association was able to benefit from Tiffany's leadership for nine years; she truly helped shape every aspect of the Drupal Association. I'm proud to have worked with Tiffany; she has been one of the most influential, talented members of our Board, and has been very generous by contributing both time and resources to the project.

Acro Media: Urban Hipster: Updates & What's New

Jue, 03/08/2018 - 17:44

The Urban Hipster (UH) Drupal 8 Commerce 2 demo site has been gaining a lot of traction lately due to some fanfare and sweet promo videos. An increasing number of people are trying it out and viewing the code (which is publicly available on GitHub). It was time for a bit of a content overhaul. Here's what's changed.

Public Domain Images

All of the imagery and icons used in the site are now created by Acro Media or taken from Unsplash.com. If you're not aware of Unsplash, they provide high quality images that are freely available to use in any way, shape or form. It's a pretty awesome service and supports the open source philosophy we in the Drupal community share.

Product Page Galleries

The biggest feature we added in this release has to do with the product pages. Products can now display a gallery of images on the product page instead of just showing the current variation. I won't get into the details here, but you can watch the video for more information. Here's an example.

More "Full" Product Examples

The UH demo was originally intended to be a sales tool for our staff. Because of this, we added a bunch of products, but only a handful were fully filled out with attributes, sample reviews, related products, etc. The rest were just placeholders to fill out the store. Now that more people are looking at it, we felt we needed more (if not all) of the products to be more robust so that it didn't matter which product you happen to look at. This was something we did in this content overhaul. Almost every product now includes multiple images, related products, variation options, etc. Here's an example.

Configuration Cleanup

Since we were adding all new content anyway, it was a good opportunity to clean up some of the attributes, product types and product variation types that weren't really needed or not well represented. A lot of people are looking to this demo for examples of configuration, so it's important that we try to keep it as clean as possible.

And that's about it! Enjoy the video and the site updates.

Ben Marshall: Load JS & CSS Conditionally in Drupal 7

Jue, 03/08/2018 - 15:00

This post was originally published on May 22, 2013 and last updated March 8, 2018 thanks to some helpful input by Steve Elkins.

Drupal 7 is a haus at combining CSS & JS files. This can help boost page performance & optimization easily, but if not used right, can do the complete opposite. In this post, we’ll go over how to load JS & CSS files based on conditionals like URL, module, node, views and more.

Before we dive in, get somewhat familiar with the drupal_add_js and drupal_add_css functions. We’ll use these to load the actual JS and CSS files.

hook_init – runs on every page /** * Implements hook_init() * * @link https://api.drupal.org/api/drupal/modules%21system%21system.api.php/function/hook_init/7.x */ function HOOK_init() { // Using the equivalent of Apache's $_SERVER['REQUEST_URI'] variable to load based on URL // @link https://api.drupal.org/api/drupal/includes!bootstrap.inc/function/request_uri/7 if (request_url() === 'your-url-path') { drupal_add_js( /* parameters */ ); drupal_add_css( /* parameters */ ); } }

Using hook_init is one of the simplest methods to load specific JS and CSS files (don’t forget to replace HOOK with the theme or module machine name).

Be careful, this method get’s ran on every page, so it’s best to use this method only when you actually need to check every page for your conditional. A good example, loading module CSS and JS files. A bad example, loading node-specific CSS and JS files. We’ll go over that next.

There’s also a similar preprocess function, template_preprocess_page you could use, but it too get’s ran on every page and is essentially the same as hook_init.

template_preprocess_node – runs on node pages /** * Implements template_preprocess_node() * * @link https://api.drupal.org/api/drupal/modules%21node%21node.module/function/template_preprocess_node/7.x */ function TEMPLATE_preprocess_node(&$vars) { // Add JS & CSS by node type if( $vars['type'] == 'your-node-type') { drupal_add_js( /* parameters */ ); drupal_add_css( /* parameters */ ); } // Add JS & CSS to the front page if ($vars['is_front']) { drupal_add_js( /* parameters */ ); drupal_add_css( /* parameters */ ); } // Given an internal Drupal path, load based on node alias. if (drupal_get_path_alias("node/{$vars['#node']->nid}") == 'your-node-id') { drupal_add_js( /* parameters */ ); drupal_add_css( /* parameters */ ); } }

Using template_preprocess_node is perfect when loading JS and CSS files based on nodes (don’t forget to replace TEMPLATE with the theme machine name). Since it only get’s run on nodes, it’s great to use when you want to load CSS and JS files on specific node types, front pages, node URLs, etc.

template_preprocess_views_view – runs every view load /** * Implements template_preprocess_views_view() * * @link https://api.drupal.org/api/views/theme%21theme.inc/function/template_preprocess_views_view/7.x-3.x */ function TEMPLATE_preprocess_views_view(&$vars) { // Get the current view info $view = $vars['view']; // Add JS/CSS based on view name if ($view->name == 'view_name') { drupal_add_js( /* parameters */ ); drupal_add_css( /* parameters */ ); } // Add JS/CSS based on current view display if ($view->current_display == 'current_display_name') { drupal_add_js( /* parameters */ ); drupal_add_css( /* parameters */ ); } }

Using template_preprocess_node is useful when loading JS and CSS files when a particular view is being used (don’t forget to replace TEMPLATE with the theme machine name).

Helpful Methods for Conditionals

Here’s a few helpful Drupal methods you can use for your conditionals. Have one you use often? Let me know in the comments below.

  • request_uri – Returns the equivalent of Apache’s $_SERVER[‘REQUEST_URI’] variable.
  • drupal_get_path_alias – Given an internal Drupal path, return the alias set by the administrator.

Flocon de toile | Freelance Drupal: Send transactional emails related to user account in HTML format with Drupal 8

Jue, 03/08/2018 - 08:00
We have several solutions to automatically send emails emitted by a Drupal 8 project in HTML format. Without being able to quote them all, we can use SwiftMailer, MimeMail to send mails from the server itself, or Mailjet API, MailGun, etc. to send emails from a third-party platform. In a few clicks, we can then emit different emails, whether they are transactional (account creation, order creation, subscription, etc.) or business (Newsletters, Activity Log, What you missed, etc. .), in HTML format. It will then remain to implement one (or more) responsive email template that will be correctly read and interpreted on most mail software. And it's probably the most important part. There remains a special case: that of all the emails emitted according to the different events related to the life of a user account (Creation, Waiting for approval, Deletion, Welcome Mail, etc.). Let's see how to simply send this emails in a HTML format too.

Amazee Labs: DrupalCamp London 2018 - Keeping it Cool

DrupalCamp London 2018 - Keeping it Cool

I attended DrupalCamp London this past weekend. This was the 6th consecutive year the event has been hosted, which is remarkable. My mission getting to the event turned out to be just as remarkable! Keep reading to find out more about both.

Fran Garcia Thu, 03/08/2018 - 10:41

Something that the organisers couldn’t control was the fact that the whole of the UK was facing the biggest freeze in recent years. This meant that trains and buses were canceled. Schools, shops, and roads were also closed. As you can imagine, getting from Birmingham to London wasn’t an easy task, but I was on a mission and decided to venture into the elements (as I wasn’t able to either teleport nor fly there - see below!)


To make a long story short, plan A and B failed due to multiple cancellations so I opted for no-plan at all - just do and keep doing until I got there. What would usually be a two-hour relaxing journey became a nearly six-hour bumpy, cold, and wet quest through the elements... but guess what? I made it to London!


But why did I want to get there so badly? Going to the DrupalCamp was reason enough but additionally, I was selected to do three different talks at the camp. I was really excited about the opportunity and wouldn't miss it for the world!

My three talks were completely different:

The slides are linked above and the videos will soon be available on the Camp YouTube channel.

I am happy with how the talks went. People were engaged and participative - I even missed lunch one day as I was answering questions for more than 40 minutes after the talk. But most importantly I think they made a difference to the people who attended. I’m glad that one way or another I could give something back to the Drupal community. A special thanks goes out to Joe Shindelar for his little push in Vienna :-)

The rest of the sessions were great too. We had amazing speakers, inspiring talks, live demos, in-depth discussions and a unique atmosphere over the whole weekend. I met people from France, Italy, Iceland, Finland, Spain and many other parts of the UK, which was great. I loved listening to their stories and knowing how people work and use Drupal too. I also realised how proud and happy I am to be an Amazee.

The keynotes were especially inspiring, stating once and again Drupal's core values and mission, talking about the community behind Drupal, its importance and the ways in which we can all help improve it. Thanks to Ryan Szrama (Commerce Guys), Chris Teitzel (Lockr) and Baddý Sonja Breidert (1xINTERNET) for sharing your experiences, visions, opinions and for being so close and approachable during the weekend.

And of course thanks, DrupalCamp London (@DrupalCampLDN #dclondon) for organising such a great event. Huge kudos to organizers and volunteers, who were all over the place ensuring that the event was successful and flawless. See you next year!

Community: Community Working Group Call for New Members

Jue, 03/08/2018 - 00:03

Are you interested in volunteer work primarily concerned with community health, conflict resolution, and Drupal Code of Conduct matters? Then the Drupal Community Working Group (CWG) can benefit from your help. We are looking to add new volunteer members to our small, but dedicated, team and we’d like to hear from you! 

About the CWG

As our Charter states “The mission of the Community Working Group (CWG) is to uphold the Drupal Code of Conduct in order to maintain a friendly and welcoming community for the Drupal project.”; this means we very often deal with conflict resolution and guidance in the handling of Code of Conduct violations involving Drupal Community members and Drupal Community spaces. Although this sometimes can take a big chunk of our time, we also work on proactive tasks involving community health, growth, and awareness. For example, we get to honor amazing members of the community with the prestigious Aaron Winborn Award as well as work on tools and processes to facilitate community health and growth.

We currently are a diverse group of five members from three continents and we are looking to continue to diversify. We come from different backgrounds, and have different experiences, perspectives, and opinions, but we all share a deep desire to help community members and have them treat one another with respect, dignity, and encouragement. 

About you

Characteristics that are in line with what we do and what we are looking for:

  • Patient and open-minded
    We are often involved in high-stress and/or highly emotional situations. As facilitators, we must be able to listen to all sides patiently and without judgment to try to fully understand the situation as best we can. Although the work we do is rewarding and necessary, sometimes the issues we deal with can be tough and emotionally draining, and individuals looking to join the CWG need to be aware that it can involve a fair amount of emotional labor.
  • Self-driven and self-motivated
    A typical time commitment for CWG members is a couple hours a week, though that can vary. We are all volunteer members and, as such, juggle our own work-life-community schedules and try to create a balance where we do as much as we can without getting burned-out. We encourage and support members taking breaks from CWG business when needed.
  • Discrete and confidential
    We often deal with sensitive and confidential information and all members are expected to safeguard any and all information we come in contact with in our roles as CWG members. Additionally, we disclose any potential conflicts of interest and recuse ourselves when appropriate.
  • Love for the community
    All members of the CWG are volunteers and donate our own time and efforts while doing work we consider important and necessary. The main drive behind our work is the health of the community and its members.
  • The desire to uphold the Drupal Code of Conduct and share the Drupal values and principles.
    This almost goes without saying, but we think it is worth it for you to take a(nother) look at the Drupal Code of Conduct.
Still with us?

If you think you’d be a good fit or know someone you think is, please reach out!

Dries Buytaert: Drupal 8.5.0 released

Mié, 03/07/2018 - 23:45

Earlier today, we released Drupal 8.5.0, which ships with improved features for content authors, site builders and developers.

Content authors can benefit from enhanced media support and content moderation workflows. It is now easier to upload, manage and reuse media assets, in addition to moving content between different workflow states (e.g. draft, archived, published, etc).

Drupal 8.5.0 also ships with a Settings Tray module, which improves the experience for site builders. Under the hood, the Settings Tray module uses Drupal 8.5's new off-canvas dialog library; Drupal module developers are encouraged to start using these new features to improve the end-user experience of their modules.

It's also exciting to see additional improvements to Drupal's REST API. With every new release, Drupal continues to extend investments in being an API-first platform, which makes it easier to integrate with JavaScript frameworks, mobile applications, marketing solutions and more.

Finally, Drupal 8.5 also ships with significant improvements for Drupal 7 to Drupal 8 migration. After four years of work, 1,300+ closed issues and contributions from over 570 Drualists, the migrate system's underlying architecture in Drupal 8.5 is fully stable. With the exception of sites with multilingual content, the migration path is now considered stable. Needless to say, this is a significant milestone.

These are just a few of the major highlights. For more details about what is new in Drupal 8.5, please check out the official release announcement and the detailed release notes.

What I'm probably most excited about is the fact that the new Drupal 8 release system is starting to hit its stride. The number of people contributing to Drupal continues to grow and the number of new features scheduled for Drupal 8.6 and beyond is exciting.

In future releases, we plan to add a media library, support for remote media types like YouTube videos, support for content staging, a layout builder, JSON API support, GraphQL support, a React-based administration application and a better out-of-the-box experience for evaluators. While we have made important progress on these features, they are not yet ready for core inclusion and/or production use. The layout builder is available in Drupal 8.5 as an experimental module; you can beta test the layout builder if you are interested in trying it out.

I want to extend a special thank you to the many contributors that helped make Drupal 8.5 possible. Hundreds of people and organizations have contributed to Drupal 8.5. It can be hard to appreciate what you can't see, but behind every bugfix and new feature there are a number of people and organizations that have given their time and resources to contribute back. Thank you!

Drupal blog: Drupal 8.5.0 is now available

What's new in Drupal 8.5.0?

This new version makes Media module available for all, improves migrations significantly, stabilizes the Content Moderation and Settings Tray modules, serves dynamic pages faster with BigPipe enabled by default, and introduces a new experimental entity layout user interface. The release includes several very important fixes for workflows of content translations and supports running on PHP 7.2.

Download Drupal 8.5.0

Media in core improved and available to all site builders

In Drupal 8.4, we added a Media API to core that drew on work from the contributed Media Entity module, but the module was hidden from the user interface due to user experience issues. In Drupal 8.5, many of the usability issues have been addressed, and the module now can be enabled normally. Media in Drupal 8.5 supports uploading and playing audio and video files, as well as listing and reusing media.

For an optimal user experience, we suggest enhancing the core feature set with the rich ecosystem of contributed modules that extends the core Media module. In future releases, we will improve the core user experience with a media library and other tools, add WYSIWYG integration, add support for remote media types like YouTube videos, and provide an upgrade path for existing basic File and Image field data on existing sites.

Settings Tray and Content Moderation now stable

Two experimental modules originally added with Drupal 8.2.0 have been steadily improving in past releases and are now stable. The Settings Tray module provides a quick solution to manage settings in context, such as moving items around in a menu block. The Content Moderation module allows defining content workflow states such as Draft, Archived, and Published, as well as which roles have the ability to move content between states. Drupal 8.5.0 also adds support for translations to be moderated independently.

New experimental Layout Builder module

The new experimental Layout Builder module provides display layout capabilities for articles, pages, user profiles, and other entity displays. Layout Builder uses the same "outside-in" user interface that Settings Tray module does, allowing site builders to edit their layouts on the actual page (rather than having to go to a separate form on the backend). The current user interface is a basic implementation but we expect it will improve significantly in the coming months.

Big steps for migrations

After over four years of work, this release marks the Migrate system's architecture stable. The Drupal Migrate and Drupal Migrate UI modules are also considered stable for upgrading monolingual sites. (Multilingual site upgrades are still not fully supported.) Support for incremental migrations is also included in this release. See the migrate announcement for further details on migrating to Drupal 8.

BigPipe by default

The BigPipe module provides an advanced implementation of Facebook's BigPipe page rendering strategy for greatly improved perceived performance for pages with dynamic, personalized, or uncacheable content. The module was added in Drupal 8.1.0 experimentally and became stable in Drupal 8.3.0. Following real-world testing, Big Pipe is now included as part of Drupal 8.5.0's Standard installation profile, so that all Drupal 8 sites will be faster by default. BigPipe is also the first new Drupal 8 feature to mature from an experimental prototype all the way to being part of a standard installation!

Groundwork for a Drupal 8 "Out of the Box" demo

Drupal 8.5.0 includes the groundwork for a new demo profile and theme from the Out of the Box Initiative, which will be a beautiful, modern demonstration of Drupal's capabilities. This will allow us to provide the demo experimentally, possibly in a future Drupal 8.5 release. (The demo profile and theme should not be used on actual production or development sites since no backwards compatibility or upgrade paths are provided.) If you'd like to see this demo in action, you can also see it in the 8.6.x development version.

PHP 7.2 now supported

Drupal 8.5.0 now runs on PHP 7.2, which comes with new features and improves performance over PHP 7.1. PHP 7.2 is now the recommended PHP version to use with Drupal 8.

What does this mean for me? Drupal 8 site owners

Update to 8.5.0 to continue receiving bug and security fixes. The next bugfix release (8.5.1) is scheduled for April 4, 2018.

Updating your site from 8.4.5 to 8.5.0 with update.php is exactly the same as updating from 8.4.4 to 8.4.5. Drupal 8.5.0 also has updates to several dependencies, including a backwards-compatible update to a Symfony long-term-support release (which will be supported for many years). Modules, themes, and translations may need updates for these and other changes in this minor release, so test the update carefully before updating your production site.

Note that Drupal 8 will require PHP 7 starting in March 2019, one year from now. If your site is hosted on PHP 5.5 or 5.6, you should begin planning to upgrade (and consider upgrading to PHP 7.2 now that it is supported). See the Drupal core announcement about the PHP 5 end-of-life for more information.

Drupal 6 and 7 site owners

Drupal 7 is still fully supported and will continue to receive bug and security fixes throughout all minor releases of Drupal 8. Drupal 6 is no longer supported. See the migrate announcement for further details on migrating to Drupal 8.

Translation, module, and theme contributors

Minor releases like Drupal 8.5.0 include backwards-compatible API additions for developers as well as new features. Read the 8.5.0 release notes for more details on the improvements for developers in this release.

Since minor releases are backwards-compatible, modules, themes, and translations that supported Drupal 8.4.x and earlier will be compatible with 8.5.x as well. However, the new version does include some changes to strings, user interfaces, internal APIs and API deprecations. This means that some small updates may be required for your translations, modules, and themes. See the announcement of the 8.5.0 release candidate for more background information.

Drupal blog: Big steps for migrations in Drupal 8.5.0

Mié, 03/07/2018 - 19:51

After over four years of work with over 570 contributors and 1300+ closed issues, Drupal 8.5.0 releases the Migrate system's architecture as fully stable. This means that developers can write migration paths without worrying for stability of the underlying system.

On top of that the Migrate Drupal and Migrate Drupal UI modules (providing Drupal 6 and 7 to Drupal 8 migrations) are considered stable for upgrading monolingual sites. All of the remaining critical issues for the Migrate Drupal module's upgrade paths and stability are related to multilingual migration support (so multilingual site upgrades are still not fully supported).

Support for incremental migrations is now also available, which means that site owners can work gradually on their new Drupal 8 site while content is still being added to the old site. When migrations (including incremental migrations) are run through the user interface, site owners will now see a warning if some data on the Drupal 8 site might be overwritten. (A similar fix for Drush is not yet available, so be careful not to overwrite data if you run a migration on the command line.) 

Upgrade instructions for Drupal 6 and Drupal 7 sites can be found in the Upgrading to Drupal 8 handbook. Your old site can still remain up and running while you test migrating your data into your new Drupal 8 site. If you happen to find a bug, that is not a known migrate issue, your detailed bug report with steps to reproduce is a big help!

Unlike previous versions, Drupal 8 stores translated content as single entities. Multilingual sites with reference fields (node_reference, entity_reference) or multilingual menus can upgrade to Drupal 8 using Drush, executing the desired migrations one by one. In this process you need to create and run a series of additional custom migrations to reflect the new entity identifiers assigned during earlier migrations. There is no automation implemented for this process yet.

Data can be migrated to Drupal 8 also from non-Drupal sources such as CSV, XML, JSON, or directly from 3rd party systems' databases. For instructions and examples, refer to Migrate API handbook.

Huge thanks again to all the contributors who made this possible.
