Reloading code & caching

[hlship]

This is a bit out-of-left field, but I tend to see things where after reloading code, with changed schemas, some of my functions appear to be checking against the old schemas, not the new ones. I suspect there's some caching going on, I don't think it's in my code. Is there a cache and, if so, how to clear it?

There is no cache, as far as I recall. However, you may have to recompile downstream code to pick up the new schemas.

For example, if you have:

(def A s/Int)
(def B {:a A})
(s/defn foo [b :- b])

then after changing A, you have to recompile A, B and foo (in that order) to see the new changes. In particular, note that schematized functions capture the schema at the time of definition.

If you are redefining classes (e.g. records), the same rules apply because the new version is actually a new Class that happens to have the same name.

If that doesn't seem to cover what you're seeing, can you please provide a concrete example? Thanks!

Did you end up figuring out what was causing the problem here? Thanks!

Give me just a little longer to try and come up with a scenario.

No rush, just wanted to check in. Thanks!
