2.1.11

We found a regression in 2.1.10 causing a runtime exception in some cases when using ZIO environment and layers, so here's a release to fix that.

What's Changed

• Fix IndexOutOfBoundsException when using reverseIterator on UpdateOrderLinkedMap by @​kyri-petrou in zio/zio#9239

2.1.10

This release brings a few important bug fixes related to ZPool and ZSTM as well as some optimizations. It also fixes a binary incompatibility that caused runtime errors when using an older version ZIO Streams together with ZIO 2.1.9.

Important note about ZPool changes

There are 2 fixes / changes to ZPool that might affect the behaviour of an application so users are advised to revise the following in cases of unexpected behaviour after upgrading to ZIO 2.1.10+.

Eager / strict initialization of ZPool's resources

In previous ZIO versions, the initialization of ZPool resources was done lazily in a daemon fiber. e.g., this code would previously print the message, but will now "hang" awaiting for the pool to be initialized to its full size:

ZPool.make(ZIO.never, 10) *> ZIO.debug("Pool initialized")

We believe that this change makes the behaviour of ZPool more predictable (and referentially transparent!) as previously there were no guarantees that the ZPool resources would be initialized during the creation of the pool. However, this might result in the initialization of the pool hanging in cases that the acquisition of the resources itself hangs. Therefore users are advised to consider adding timeouts to the resource initialization effect.

Strict finalization of ZPool resources

In previous versions, it was possible for the ZPool finalizers to be interrupted, which would lead to potential leak of resources (see this issue for more info). Starting with ZIO 2.1.10+, closing a ZPool requires all of the resource finalizers to finish first. As with (1), this might lead to some unexpected behaviour if the finalization of a resource hangs indefinitely, so users are advised to add timeouts to the finalizers of resources used with ZPool.
