v1.0.0 - simple.DAG released!

v1.0.0

The first official release version: including simple.DAG.

simple.DAG

• Workflow:
  • No limit to the complexity of a directed acyclic graph.
  • Single input and single output.
  • Canceled at any time during execution.
  • Shipped with any loggers.
• Transit:
  • TransitInterface: Allow custom transits.
  • Any inputs and outputs(except the initial input and final output).
  • The worker accepts the incoming context parameter and allows receiving Done() signal.
  • Any worker error will terminate the execution and notify all the loggers to record events, including panic() and recover from it.
• Logger:
  • LoggerInterface: Allow custom loggers.
  • Predefined four log levels.
  • Default logger: Log events are output to the standard output and standard error.
  • Error collector: Collect errors generated during workflow execution.

No new changes against the previous version(#8).

v1.0.0-beta.1 and the earlier versions are not recommended to use.

v1.0.0-beta.1

v1.0.0-beta.1

The first beta release version: including simple.DAG.

Starting from this version, no new features will be added, only bug fixes and documentation (including use cases) will be made. After releasing no less than three beta versions and no defects are found, the official version will be released.

v1.0.0-alpha3 and the earlier versions are not recommended to use.

v1.0.0-alpha3

v1.0.0-alpha3

The third alpha release version: including simple.DAG.

During the next week of testing, if no serious defects are found, this version will be the last alpha. From now on, all features will be frozen, no new features will be added, and beta versions will begin to be released.

v1.0.0-alpha1 is not recommended to use.

v1.0.0-alpha1

v1.0.0-alpha1

A first release version: including SimpleDAG.

SimpleDAG

Features:

• Supports describing and executing a workflow of arbitrary complexity as a directed acyclic graph.
• Supports tracing and logging interfaces(SimpleDAGLogger), including default logger(SimpleDAGJSONLogger).

Notice:

You need to ensure that

• your workflow does not form a loop.
• each channel is used and only used once.

SimpleDAG does not check for the above issues.
