Full Changelog: v0.2.1...v0.2.2

dora-rs v0.2.1

v0.2.1 (2023-03-22)

Features

• Make dora-rs publishable on crates.io

Fixes

• Avoid blocking the daemon main loop by using unbounded queue
• Inject YAML declared env variable into the runtime
• Use rustls instead of system SSL implementation

Other

• Refactor python error
• The first letter of rust should be lowercase in the command
• Add documentation to the cli within the helper mode
• Update to safer-ffi v0.1.0-rc1
• remove unused variable: data_bytes
• Clean up: Remove workspace path
• Decouple opentelemetry from tracing
• Remove zenoh dependency from dora node API to speed up build
• Update to Rust v1.68

dora-rs v0.2.0

v0.2.0 (2023-03-14)

Breaking

• Redesign: Create a dora-daemon as a communication broker
  • New dora-daemon executable that acts as a communication hub for all local nodes
  • Large messages are passed through shared memory without any copying
  • Replaces the previous iceoryx communication layer
  • Small API change: Nodes and operators now receive events instead of just inputs
    • Inputs are one type of event
    • Other supported events: InputClosed when an input stream is closed and Stop when the user stops the dataflow (e.g. through the CLI)

Features

• Better Error handling when operator fails
• Send small messages directly without shared memory
• Send all queued incoming events at once on NextEvent request
• Don't send replies for SendMessage requests when using TCP
• Allocate shared memory in nodes to improve throughput

Fixes

• Manage node failure: Await all nodes to finish before marking dataflow as finished

Other

• Use DoraStatus from dora library in template
• Simplify: Replace library_filename function with format! call
• Refactor Rust node API implementation
• Remove code duplicate for tracing subscriber and use env variable to manage log level.
• Add daemon to the release archive
• Remove remove_dir_all from Cargo.lockas it is vulnerable to a race condition according to dependabot
• Update the documentation to the new daemon format
• Removing legacy libacl which was required by Iceoryx
• Remove unimplemented CLI arguments for now
• Update zenoh to remove git dependencies
• Fix cli template to new daemon API
• Cleanup warnings
• Dependency updates

dora-rs v0.1.3

v0.1.3 (2023-01-18)

• Package DoraStatus into dora python package: #172
• Force removal of Pyo3 Object to avoid memory leak: #168
• Bump tokio from 1.21.2 to 1.23.1: #171
• Create a changelog file: #174

v0.1.2

Releasing the v0.1.2 that fixes:

• the infinite loop in the coordinator. #155
• simplify the release process. #157
• Use generic linux distribution. #159

Releasing `dora-rs` v0.1.1

This release fixes some of the issue of deployment previously present in the 0.1.0.

This release contains fixes for:

• Python linking using pypi release but also a redesigned python thread model within the runtime to avoid deadlock of the GIL. This also fix an issue with patchelf.
• A deployment separation for ubuntu as the 20.04 version of dora and 22.04 version of dora are non-compatible.
• A better tagging of api for dora Rust API.

We have unfortunately removed macOS and Windows from prime support as we want to focus for Linux at the moment that is going to be used on small computer and cloud environment.

dora-rs v0.1.0

This is our first release of dora-rs 😄

The current release includes:

• dora-cli which enables creating, starting and stopping dataflow.
• dora-coordinator which is our control plane.
• dora-runtime which is manage the runtime of operators.
• custom-nodes API which enables bridges from different languages.
