Out of memory while compiling about pickling

[heathermiller]

Thanks for taking the time to try scala/pickling and to report this!

Funny story – I can compile gatling-debug, but this totally ridiculous thing happens:

[success] Total time: 481 s, completed Sep 10, 2013 10:09:24 PM

We made some changes yesterday and republished the artifact, will see if those changes help your use case. In any case, we're on it, thanks :)

[Skeebl]

Thanks for your answer.

Indeed, 481 seconds seems a bit excessive to compile a few classes ;) Did you allocate more than 4GB to the heap ?

The new artifact does not seem to resolve the problem. I hope this problem will not delay too much your release.

[heathermiller]

Yep, it was also with a 4GB heap. We're on it though – ideally we'll have this resolved today. Thanks for hanging in there :)

Got a similar problem in a project of mine, involving a (not too overly complex) trait + case class hierarchy.
It seems to me that (guessing from the pretty long log-implicits output) the picklers of the classes that are lowest in hierarchy are generated over and over when referenced by the trait they implement in other case classes?

I'm on scala 2.10.2, sbt 0.13.0, pickling 0.8.0-SNAPSHOT.
This is the project, with this file in particular - i'm calling pickle on a Message directly in this file.
And i'm still not sure if master actually compiles.

Edit
This small test is already too much for my pc...:

Yay!

Pushing a fix soon...

[heathermiller]

Philipp's successful compile was for @Skeebl's gatling project. @ephe-meral, we'll also test it with your entice project and your gist – thanks a lot for sharing them.

...This has been a hell of a bug to fix. It required some pretty significant reworking to how we deal with collections. Thanks to @phaller for his valiant effort!

Thanks for you dedication to this problem. I'll test it as soon as the snapshot is updated.
