ProxyStore v0.6.5

Highlights

This primary goal of this release is to improve some of the subtle challenges of working with Proxy objects. Specifically, that (1) serialization can fail on Proxy class attribute access, (2) serializers/compute frameworks will accidentally resolve a Proxy instance when doing simple operations like checking types or hashing, and (3) mypy cannot infer the types of most operations on a Proxy[T].

• ProxyStore now uses a new slots-based Proxy implementation which will improve serialization compatibility.
• Store.proxy(..., populate_target=True) will now cache some attributes of the target object so that calling hash() or isinstance() on a proxy does not require the proxy to be resolved.
• An FAQ guide has been created to discuss these common pitfalls and their remedies.
• The proxystore.mypy_plugin, when enabled, allows mypy to infer attribute types on Proxy[T].
• The Store now has a register flag for configuring a Store instances to always register themselves.
• Added the StaticLifetime

Upgrade Steps

pip install --upgrade proxystore    # or proxystore[all]
