Mark Jaquith has noted a cool new feature for WordPress 2.2 that some plugin and theme creators are going to love.
So the feature I’ve put into WordPress 2.2 is what I call plugin sandboxing. Before a plugin is activated or a plugin is edited, it is tested in a temporary fashion (that is, without being permanently activated). If it passes the test, it is activated for real. If it doesn’t pass the test (it’s throwing a fatal error that would normally take down your WordPress install), it is deactivated, and you get a nice error message telling you what went wrong. If the fatal error was caused because you edited an active plugin, the â€œUpdate Fileâ€ button changes to â€œUpdate File and Attempt to Reactivate,â€ so that once you correct your typo, the plugin will go back to being activated, without requiring you to go back and manually activate it.
If you never activate a flawed plugin or never make a typo when editing your plugins, you’ll never know this functionality is there. But some day you just might slip up, and now WordPress will cover for you.
This sounds like a really smart feature that is very “why wasn’t this done before!?”
A brilliant move in my mind by the Automattic team.
Note: It wasn’t from the Automattic team, though I guess I just assume that Mark should be…
