JDBC Rollbacks and Exceptions

Hey All, Has anyone found a way to "reset" a connection after a rollback? It seems like after an exception is triggered, the connection cannot be used again, even if you just want to rollback and continue with the next insert. This is a problem if you want to both clean the database state by r

Manifold streams/deferreds raising errors downstream of a sink

Hey All, I'm trying to build a library that exposes manifold streams for data producing applications. The intention would be for these apps to s/put! to a sink stream returned by the producer function. However, I need to take the value that is put in and pipe it into some other function before I

There's this one from uswitch http://oobaloo.co.uk/dynamic-error-capture-with-clojure but it doesn't really have a motivating example to highlight why that particular approach is better. Or this one which hints at monads: http://adambard.com/blog/acceptable-error-handling-in-clojure/ I also f

Re: Managing database schema

One problem we found with ragtime is that if multiple developers are working on a schema simultaneously, it's quite easy to get into a state where `lein ragtime migrate` will complain about finding a migration it doesn't expect. I think you can work around this by rolling back to the nearest co

Education on Dynamic Binding

This page on Jira says that dynamic binding should be documented as "The Clojure Way" to do error handling. Was this ever done? I managed to find a few blog posts discussing approach but nothing official. http://dev.clojure.org/display/design/Error+Handling Cheers, Andy -- You received this m

Minimum Viable Database Component

Hi All, I'm trying to follow the "component" architecture for an app I'm working on and wondered if I was missing something. In the "Just enough structure" talk, one of the examples Stuart presents is a DB component that contains just a small selection of DB related functions (i.e. insert, and

Question about test.check, and knossos

Hi All, Lately I've been exploring the world introduced to me by watching the John Hughes' quickcheck video from clojure west. Awesome stuff! Eventually I found the "testing for fun and profit"[1] paper which left me wanting to test my apps using a model based system like the paper describes. I

combining methods

Hey All, Does clojure have an equivalent of either CLOS's `call-next-method' or java's super? For example, given the multi-method, and the interfaces ICDISCElement and IODMDef, where IODMDef extends ICDISCElement (defmulti validate class) (defmethod validate ICDISCElement [elem] ;;generi
