The BETA notice below is important. Please read it carefully before you proceed.
UpdateSafely™ is our trademarked WordPress update system. This new 2.0 release has been recreated from the ground up and is designed to take care of a big part of your WordPress maintenance routine so that you no longer have to.
If you run a WordPress care plan service, or simply don’t have the time to regularly test and then run WordPress updates, UpdateSafely can take care of this for you, and will alert you to any potential update issues should they arise.
We’re very excited to open up UpdateSafely 2.0 for beta testing, and this guide will walk you through to how it works and how to set it up.
How it Works
UpdateSafely works by cloning your live production site to a canary site, then it runs any available WordPress updates (core, theme, and plugin) on this canary site. Once the updates have completed, it will then run a sophisticated visual comparison of your live site and the newly updated canary site.
If the visual comparison is within your set parameters (for example, if they are visually at least 99% the same), it can then run those updates for you on your live website, removing the need for you to manually update and check both your own and your client’s websites. Alternatively, you can set it so that UpdateSafely will simply provide you with a report, and leave the decision on whether to run the updates up to you.
Save your time, money, and effort
As you grow your business and add more websites to your hosting / care plan service, this feature will help you save a considerable amount of time each month, as well as the cost of running these updates on all the websites you manage yourself. This includes both the financial and cost of wasted hours of monotonous updating/testing on staging, and then again updating on your live sites, that could have been used more productively.
Time spent performing tedious tasks can be a huge productivity killer. You’ll win on all fronts.
UpdateSafely requires a server with a minimum of 4 CPU cores to operate.
Part 1. UpdateSafely Default Settings
You can configure the default settings for UpdateSafely™ inside your account settings. Login to your account and click on your name to display the dropdown pictured below. Then, inside your settings, click through to Default UpdateSafely Settings from the left-hand sidebar.
Here you’ll see two panels. The first is the UpdateSafely Frequency setting. Here you can set how often you would it to run, and choose from once per day, once every 2 days, once every 3 days, or weekly.
UpdateSafely Canary Site Defaults
The second is the UpdateSafely Canary Site Defaults. These settings are automatically applied to newly created canary websites, however, you can also configure these on a per-site basis (more in part 3).
Our defaults are going to serve most use cases very well and are a safe bet for performance and accuracy.
Report only (do not update)
This option allows you to choose whether UpdateSafely runs updates on your live websites or not. By default, it’s set to report only, which means it will run the visual comparison tests and then create a report for you, but will not run updates. If you would like to set updates to run, you can toggle this option off.
Use only target provided target URLs
Inside your canary site configuration modal you can set specific URLs for testing. This options allows you to choose whether UpdateSafely sticks to only these pages or not. We recommend that you choose a few specific, important pages to test against for the best results.
Pre-Snapshot Delay (ms)
Set how long UpdateSafely should wait before taking a snapshot after the page has loaded. This allows you to factor for things such as font rendering etc.
Post Type URL Limit
This allows you to limit the number of URLs tested for each post type. This is in addition to any URLs included via the
file (details in part 3).
This one is very important. This sets allowed difference that the production website and canary website can be off, in terms of a percentage, before it is considered a failure.
The default setting is “2“, which means that the allowable visual difference between your live site and it’s canary website is 2%. If they aren’t 98% visually the same, then this is considered a failure and updates will not take place. Details and screenshots will be in your report (more details in part 5).
Viewport Width & Viewport Height
These two settings combine together to set the viewport dimensions in which testing will take place. The defaults are pretty solid, but if you would like to alter them to fit your own custom “screen size”, you can do so here.
Async Capture Number
Limit the number of asynchronous screen captures.
Async Compare Number
Limit the number of asynchronous screen capture comparisons.
Part 2. Activating UpdateSafely
As mentioned in the introduction, this feature requires a minimum of 4 CPU cores to operate. Without this, UpdateSafely cannot be activated.
To activate UpdateSafely on your servers, head to the servers page inside your GridPane account and click on the server name to open up its configuration modal.
Here, you’ll see the new tab, and a toggle to activate it on your server.
Once activated it will run once a day at a random time between 1AM and 5AM.
To activate UpdateSafely to run automatically on your websites, you will also need to ensure that you have it toggled ON in your individual website settings. These can be found by heading to the Sites page inside your account, and clicking on your domain name to open up the configuration modal.
From here, click through to the BETA Settings tab, and ensure that “Automatic Updates” is toggled ON.
Part 3. Configuring Your Canary Websites
As you create new websites, you have the option to also create a canary website (and of course a staging site), at the same time, but you can also create and delete a canary website any time you would like to do so on the Updates page in your account.
To activate or delete a canary site for any of your live production sites, just hit the toggle.
Then, click on your canary websites domain name to open up the configuration modal.
Here you’ll see the settings tab. This allows you to adjust the default settings covered in part 1 for your individual websites. You can also reset them back to your defaults any time by hitting the Reset to Default button.
Target URL List
Here you can set a list of your websites pages that you would likely UpdateSafely to specifically test against. Add each of your pages, one per line, and then hit update. This only requires the /page specific part of your URLs, not the full address.
Here you can set any pages that you NEVER want UpdateSafely to run comparisons for. Add each of your pages, one per line, and then hit update.
Part 4. Visual Comparison Testing
Now that you’ve activated UpdateSafely on your server and at least one website, it will automatically run between the hours of 1AM and 5AM, at the interval that you’ve configured inside your settings page (once per day, once every 2 days etc).
You can also run it manually at any time by clicking on the Manual Run button for your canary site.
The UI will notify you once the test begins and completes, and it the results will be compiled into a report.
If you’re testing on an existing server, and not a newly created server, the first manual run may take a few minutes to get started while it prepares and installs some necessary components. You may need to wait a few minutes and then try again if the first run doesn’t complete. After that first run you should be all set and there won’t be any further delays on future tests.
Note that for large websites, it can take some time to clone and run updates.
Part 5. Reporting
UpdateSafely will create a report each time it runs. You can view the results of the most recent run by clicking on the “Results” link in the Comparisons column.
The will open a page that looks as follows:
The report will let you know how many comparisons have passed/failed, and you’ll be able to view screenshots from the live site and canary site side by side, and also open each of these up individually to check for visual anomalies.
If your using the report only option and would now like to have UpdateSafely run the updates, you can open up the site configuration modal, toggle off “Report only (do not update)”, and then hit the manual run button. UpdateSafely will then re-run the tests and update your website upon completing (assuming all comparisons pass once again).
When a test does fail, you’ll see red cross in the “Last Updates” column like so:
And your report will give you a detailed look at where things have gone wrong. Here’s an example of a site I purposely caused to fail by altering the typography of it’s parent theme (never make changes in a parent theme), which is was overwritten (fully deleted) when the parent theme is updated by UpdateSafely:
This test was set to fail if there was a 1% variance, and the changes I made to the typography were enough to ensure that UpdateSafely would not have gone ahead with the updates had there actually been a genuine issue. All 12 tests have failed (I cut the image above short).
Each of the screenshots contained in the report can be viewed at full size so you can get a full look at the live pages and test pages and diagnose where things have changed after your core/theme/plugin updates have taken place.
For a test like this you could then push your live site to staging, and then update things one by one until you find the cause of the issue, all without harming your live production website.
