Hi, stumbled on a nasty bug in Clojure. I'm transferring Clojure objects
around using java serialization. When de-serializing a List
(clojure.lang.ASeq) it has a hashCode of 0. This means lookups for the
object in HashMaps PersistentHashMaps HashSets etc fail. The pre-serialized
version of the
Yeah, you probably shouldn't rely on this but I think it will still
work. I have done something similar before when reading from 3
databases simultaneously (3 nested with-connection and
with-query-result calls) and I believe (connection) is only called
once when creating the prepared statement.
couchbase-clj is a Clojure client for Couchbase Server 2.0.
This library provides a thin layer of Clojure that simplifies the
complicated Java interface.
couchbase-clj 0.1.0 is the initial release.

I'm glad this issue caught my eye. I disagree with this change as well, and
I hope it will be reconsidered (see alternative solution below).
I strongly agree with what is already said on the JIRA page by Joseph
Smith. What syntaxes will we support? Do we add the latest and greatest

Probably the best way to get basic maths functions in Clojure is to
use java.lang.Math.

I would recommend serializing as strings via pr/read over Java
serialization, but this still sounds like a legitimate bug.

I don't think that's a realistic option for me. I have java objects
embedded in the Clojure forms, and the graph is pretty big.

I can confirm I am seeing the behavior you describe under Clojure 1.4...
user= (serialize! [1 2 3 4 5] TEST)
nil
user= (.hashCode (deserialize! TEST.ser))
29615266
user= (serialize! [a b c d] TEST2)
nil
user= (.hashCode (deserialize! TEST2.ser))
3910595
user= (serialize! '(a b c d) TEST3)
nil
Lazy-seqs also seem to behave:
user= (serialize! (map inc [1 2 3 4]) TEST4)
nil
user= (.hashCode (deserialize! TEST4.ser))
