All WordPress.com code is managed using the Subversion revision control system. Subversion (SVN) is the only way to access and update code on VIP Hosting.
Accessing SVN #
To get SVN Access to your theme, please first make sure you have Two-Step Authentication enabled.
Two Step Authentication drastically reduces the likelihood that someone could gain unauthorized access by adding a second, very hard-to-guess log in requirement to your user account. To learn more about Two Step Authentication, read the support page or contact VIP.
Once that’s all set, you can request for SVN Access via your VIP Dashboard, under the “VIP” tab:
Once read-write access has been granted, you’ll receive an email with the subversion repository URL, which is specific to your site. You’ll also receive read access to our shared VIP plugins. For more details about our shared plugins, please see the plugins section of this site.
All code development and testing should be done in your own local development environment. Only tested code should be committed to WordPress.com.
Committing Code #
Once you have read-write access, you can commit your code directly. Once you do, it is spot reviewed for security and performance concerns, and then deployed to server clusters in all of our data centers.
For your benefit, we take code quality, security, and performance very seriously. Every commit is spot reviewed by someone on the VIP team before it can be deployed. It’s really important to include a detailed commit message to help expedite your review. Please take a look at our deploy review guidelines. Code changes are usually deployed within a few hours during US business hours, but usually much faster (within an hour).
We do expect all committed code be thoroughly tested and follow our best practices guidelines. If we see repeated mistakes, we will revoke write access.
Please check with us before committing very complicated or large chunks of code. If in doubt, it’s best to check with us first by submitting a ticket. It’s a lot less work for everyone (including you) if we’re able to take a look at it before committing than having to revert the change later. We also greatly appreciate if you commit often and with each functionality as a separate commit (if possible) rather than waiting and pushing a bunch of code to us all at once. It makes the code easier to review if we’re reviewing things in chunks.
We also like to review all plugins prior to committing them to your VIP repo. We have reviewed a small, but growing list of plugins, and modified some of them to make them more stable, secure, and perform better. Since these plugins have been pre-approved, we would prefer you use these plugins if possible if you need functionality similar to what they provide. Please see the Plugin Review Process if a solution isn’t yet available.
File Types That Are Auto-Deployed #
We auto-deploy commits that consist entirely of static CSS or image files. If there are no other pending deploys for your theme, your CSS design changes and image commits will be deployed almost immediately with no review. If you want to ensure that a commit is auto-deployed, be certain that it only contains the file types listed below and does not have any non-auto-deploy commits in front of it. It’s worth noting, too, that even adding a new directory to a commit will prevent it from auto-deploying. So if you commit all image files inside a newly added directory, that commit will not auto-deploy.
File types that auto-deploy:
Deploy Status #
At VIP → Dashboard (
/wp-admin/admin.php?page=vip-dashboard), you can see the current deploy status.
Commit Messages #
All commits on the VIP repo should be accompanied by a Good Commit Message.
Reverting Code #
A detailed document on how to revert via svn can be found here, Rolling Back / Reverting Changes to Your Theme Using Subversion.
If you’ve committed code you’re not happy with and would like to revert, you can do so from your local checkout. Simply use the command “
svn merge -c-64320 .” where “64320” would be the revision you’d like reverted. After running that command, you’ll need to commit your revert. You’ll want to use a commit message similar to “Reverted r64320 because [explain your reasoning]”.
Note that the revert will need to be deployed as well and you can open a ticket requesting that.
Sharing Access #
Some development teams to have one person with VIP SVN Access, who is responsible for peer-reviewing and committing code on behalf of their team. That one person is responsible for reviewing the code to make sure it follows VIP Best Practices, as we will revoke access if we see repeated mistakes.
However, we take security very seriously – should we discover that you are sharing login information across your team, we will immediately revoke access.
Commit and Deploy Notifications #
When a code commit is deployed to WordPress.com, an email notification is generated to every WordPress.com user who has access to the theme’s SVN repository.
