Implement a purge method

[javorszky]

For easy transient deletion

[julien731]

Completely agree with that. It would be really useful. Also, I'd love to see a method for clearing all TLC transients at once.

Problem with bulk clearing transients is that it's not in API since Object Cache back ends might simply not have any way to.

So any bulk clearing ends up specific to database storage alone.

Hm... would clearing a specific transient work though? Related: if I want to purge all things that begin with _transient_tlc_, and site has object cache, how would I go about doing that?

[Rarst]

That's the thing — it's not certain that arbitrary back-end implemented has a concept of "things that begin with". So API only goes as far as key/value store of separate individual items.

Every different back-end would need custom implementation of it (if at all possible to implement for it).

Ah,, because if they store it with an md5 hash then... brilliant... :/
