Two references to identical object come back as copies of object

[yn]

Consider the following:

user> (def m1 {:a 1})
#'user/m1
user> (def m2 m1)
#'user/m2
user> (identical? m1 m2)
true
user> (def r {:m1 m1 :m2 m2})
#'user/r
user> r
{:m1 {:a 1}, :m2 {:a 1}}
user> (identical? (r :m1) (r :m2))
true
user> (def r2 (nippy/thaw (nippy/freeze r)))
#'user/r2
user> (identical? (r2 :m1) (r2 :m2))
false

In the example as given it's more or less benign, but the same behavior happens when the reference is to Java objects where identity matters.

Hi Yuri,

Object graph identity isn't currently something Nippy attempts to address. Ideas and/or PRs welcome if this is something you'd find useful!

Cheers :-)

Closing this as we've worked around this identity path in our code.
