ZIO 2 upgrade / migration issue

11

Happens only after upgrade: ``` java.lang.NoClassDefFoundError: Could not initialize class java.lang.StackTraceElement$HashedModules ``` Running on Azure JDK.

Support Scala Native

29

Scala Native does not support multi-threading, but that shouldn't be an issue, generally, because ZIO shares CPU between fibers. Just need to make sure no blocking code is used in...

Add ways to pack Chunk booleans into byte, int, or long

6

**ISSUE** There is a way to go from `Chunk[Byte]` (or after #6849, `Chunk[Int]`/`Chunk[Long]`) to `Chunk[Boolean]`, with efficient / specialized operations designed for packed bits. However, the reverse operators do not...

Optimize performance of WeakConcurrentBag

3

**ISSUE** In ZIO 2, `WeakConcurrentBag` is used for storing root fibers. However, this structure has not been optimized, which means if there are large number of daemon fibers, it may...

It should be possible for ZIO Test to interrupt wayward scope closure: ```scala ZIO.addFinalizer(ZIO.uninterruptible(ZIO.never)) ```

Improve performance of EqClass

18

Currently, `EqClass` is defined as so: ```scala trait EqClass[A] { def equal(first: A, second: A): Boolean } ``` Unfortunately, we have no guarantee that such implementations of `equal` will first...

Augment IO and IO.type with helper methods for Disjunction, Maybe

6

Now that Scalaz 8 depends on ZIO (which defaults to `Either` and `Option`), some convenience functions are missing. This ticket is to introduce such convenience functions by adding methods to...
