Warning when asking for implicit picklers/unpicklers

[jvican]

implicitly[Pickler[(Int, List[String])]]

The above code snippet produces this beauty:

[warn] /data/rw/code/scala/spores/spores-pickling/src/test/scala/scala/spores/run/pickling/PicklingBinary.scala:58: method lookupPicklee in package internal is deprecated: Use currentRuntime.refRegistry.pickle.registerPicklee instead
[warn]       implicit val p = implicitly[Pickler[(Int, List[String])]]
[warn]

Why are you relying on registerPicklee? Why not picklers.genPickler? Isn't that part of refRegistry and therefore it's related to the bookkeeping of circular references? Why do you need that for a simple pickler/unpickler of a tuple?

This only affects scala pickling v0.11.x.

Most of the warnings have disappeared with #400 but some of them persist.

This is actually a warning about "sharing". registerPicklee is used to determine if we have a cycle in the pickle-object-graph. It actually has nothing to do with runtime pickler generation (or genPickler).

It's most liekly due to some stale code in sourcegen.scala or elsewhere.
