Sync: Add links when expanding posts at a later stage

[darssen]

Fixes https://github.com/Automattic/vulcan/issues/297

Proposed changes:

When syncing posts, we used to expand them via the filter_post_content_and_add_links. This was originally done before sending, but after dedicated sync was created, we decided to move it to before enqueuing the actions.

Since sometimes the links like permalink are not available. The approach here is to separate the filtering part from the adding links.

The expectation is that adding the links before we send the action, as we used to do will allow us to fetch the proper links.

The possible problem here is that with Dedicated Sync enabled, we would be fetching those fields on init because this is when we spawn the next dedicated sync request.

Other information:

• Have you written new tests for your changes, if applicable?
• Have you checked the E2E test CI results, and verified that your changes do not break them?
• Have you tested your changes on WordPress.com, if applicable (if so, you'll see a generated comment below with a script to run)?

Does this pull request change what data or activity we track or use?

No

Testing instructions:

The initial idea here is to test that we are still properly populating the links.

In a connected Jetpack site with this patch.

• Create a post and publish it.
• Check that the sync action jetpack_sync_save_post The second one, when the post is published, has the proper permalink.
• Update the post.
• Check that the permalink is still showing in the action.

Now test with a plugin that will change the permalink like Yoast SEO.

• Create a post and publish it.
• Check that the sync action jetpack_sync_save_post
• Update the post, but this time by updating Yoast SEO slug parameter which will change the permalink.
• Check that the permalink in the jetpack_sync_save_post has changed.

Bonus points if tested with WPML plugin as described in the links inside the issue

Are you an Automattician? Please test your changes on all WordPress.com environments to help mitigate accidental explosions.

• To test on WoA, go to the Plugins menu on a WordPress.com Simple site. Click on the "Upload" button and follow the upgrade flow to be able to upload, install, and activate the Jetpack Beta plugin. Once the plugin is active, go to Jetpack > Jetpack Beta, select your plugin, and enable the update/sync-add-links-when-expanding-posts-in-before-send branch.

  • For jetpack-mu-wpcom changes, also add define( 'JETPACK_MU_WPCOM_LOAD_VIA_BETA_PLUGIN', true ); to your wp-config.php file.

• To test on Simple, run the following command on your sandbox:

  bin/jetpack-downloader test jetpack update/sync-add-links-when-expanding-posts-in-before-send
  

  bin/jetpack-downloader test jetpack-mu-wpcom-plugin update/sync-add-links-when-expanding-posts-in-before-send

I know this is still in progress however I left some related thoughts in D152661-code.

Mostly concerns around removing a public method instead of deprecating and the performance cost of running array_map twice in expand_posts

Testing with WPML and consistently getting wrong permalinks unfortunately. Not sure if this is worth pursuing if we are not able to get the right permalinks with the WPML plugin since it's one of the main reasons we are making this change..

Does the fix in https://github.com/Automattic/jpop-issues/issues/8721 get the proper permalinks?

It doesn't for me, I tested that too.. I was testing with the latest WPML version on trunk and adding the suggested filters via Code Snippets
