Functional Changes from Evolution

Changes from MODX Evolution to MODX Revolution¶

Tag Syntax¶

Tag syntax changed; see the Tag Syntax changes.

Parsing Order¶

Evolution parsed a whole page through eval; Revolution parses tags in source order, as they occur:

• Don't put Snippet calls that assign placeholders at the end of a Resource, or after the Resource. The placeholders will be blank, because the Snippet has not executed yet.
• Tags can now have tags within their properties. [[mySnippet? &tag=test[[call]]``]] is valid.
• Using =, ?, ! and * in a Snippet property is now allowed.

No More 5000-Document limit¶

Later Evolution versions mostly lifted the 5000-document limit but kept a performance cost; Revolution removes it at the caching level.

Even so, a site with more than 10,000 Resources is usually designed the wrong way: for repeated pages such as inventories or e-commerce, write custom Snippets that read their own database tables.

Security¶

The access permissions system was rewritten as an ABAC-based system; see Security.

Error Page vs Unauthorized Page¶

On a protected front-end page, anonymous users are redirected to the Error (page not found) page, not the Unauthorized page: without the "load" permission a resource counts as nonexistent.

To send them to the Unauthorized page instead:

1. Create an Access Policy called "Load" and add a single Permission: Load.
2. Create a Context Access ACL entry for the anonymous User Group with a Context of "web," a Role of "member" and an Access Policy of "Load."

FURL Suffixes and Prefixes -> Content Types¶

The friendly_url_prefix and friendly_url_suffix settings no longer apply; Revolution handles this with Content Types.
