v0.13.0

Compare Source

Ractor 0.13.0 is released

This is mostly a cleanup release with #​281 however there is a breaking change with the FactoryArgumentsBuilder such that we now use bon for compile time safety! This changes the builder signature a bit, hence the major version bump.

Otherwise this is mostly cleanup logic, debug structs, comments, etc.

v0.12.4

Compare Source

Ractor v0.12.4 is released!

In this release there are 2 primary changes

1. We're adding the ability to runtime inspect the message type of an untyped ActorCell which can be helpful for supervision flows
2. We're also adding helpers for interacting with a supervisor's children (retrieval of the children, stopping them, and draining them) without having to have the supervisor keep additional handles around

Both are in #​277

v0.12.3

Compare Source

Ractor v0.12.3 is released!

While this release contains a single PR, there's a lot in here (see #​275 for the full context)

1. Debug implementations to all public types
2. A new RetriableMessage structure to facilitate automatic retries in factories
3. Factories can now be utilized without the async-trait crate! (This has been asked a couple times and is now resolved #​272 #​248)

v0.12.2

Compare Source

Some stat collection was lost in merging various branches. This fixes a fix on another branch that was an oversight and should have been collected stats (right now they'll report 0). #​273

v0.12.1

Compare Source

This release fixes a bug in the factory's default queue implementation regarding the calculation of the number of TTL discarded items

v0.12.0

Compare Source

Ractor version 0.12.0 is released!

In this major breaking change version the following changes are included

1. Factories have a general stats package which can be injected in order to capture stats about factory and worker ops as needed #​264
2. RustConf'24 links have been provided (main README.md)
3. Gracefully draining of specific actor's message queues is now supported #​268
4. Factories have an added query to capture the number of currently processing messages by workers #​267
5. @​stalkopat added a fix for remote actors in process groups were always joining the default scope #​269
6. @​texascloud added tracing::Span propogation between messages between actors so we can capture proper span attribution (essentially using tracing to trace the flow of a message through various actor properties) #​266

Thanks to all the new contributors on their help with this release!

v0.11.2

Compare Source

Ractor v0.11.2 is released!

This contains another performance improvement #​263. Further reducing memory utilization by ~18% for actors as well as other perf wins.

v0.11.1

Compare Source

Ractor v0.11.1 includes additional performance improvements!

We've further reduced message processing latencies in benchmarks and memory utilization of actors created. See #​261 for more details

v0.11.0

Compare Source

Ractor V0.11.0 is released!

This is a major API break since we're deprecating actor monitors. Having not found a reasonable use-case for them, we've experienced that utilizing DashMap's for every actor is causing a large memory hit (~34kb/actor). In an effort to support higher-actor count services, this is a significant amount of memory utilization.

By removing the DashMap's and having just a single HashMap for the supervision tree, this can save us a significant amount of memory.

However removing monitors is an API break.

This also has a ~50-60% increase in actor spawning performance.

See #​260 FMI

v0.10.4

Compare Source

Ractor v0.10.4 is released!

This release primarily includes a fix for post_stop where we were not waiting the proper time in the actor lifecycle before notifying listeners that the actor had exited. It should only be notified after post_stop is completed.

Issue: #​254

Edit: re-publishing this tag with a small cargo tweak with valid category slugs

v0.10.3

Compare Source

Ractor v0.10.3 is released!

• Fixed #​240
• Exposed some crate-only properties so they're available for users wanting to implement Router or Queue traits themselves.

v0.10.0

Compare Source

Ractor Version 0.10.0 is now released!

This is a significant API break with a few points in ractor.

Code cleanup

First is the resolution of #​164 which required renaming a few enumeration variants in (SpawnErr, ActorErr, and SupervisionEvent). These are to better match current functionality (instead of Panic variants they're now Failed variants) as actors can't only fail on panic (which was the original design).

Factories

Secondly is a major rewrite of Factorys to support trait-based insertion of routing and queuing logic. This

1. minimizes dependence on non-used generics (i.e. requiring a priority implementation even though no priority used)
2. Adds functionality (dynamic worker pool, dynamic queueing depth, more discard functionality for shedding newest or oldest jobs, factory lifecycle hooks, etc)
3. Increases performance by minimizing clones for some types (since Box'd types aren't needed for Sync safe structures, so they've been moved to Arc.

See the full details and changes in #​237
