This change will improve exception handling of processes.
At the moment, when a process throws an uncaught exception, the kernel will catch and log the exception, stop the offending process and then continue. This approach however might cause the user to overlook possible exceptions in processes and does not give any ability to the user for handling these exception.
This change modifies the kernel implementation and specification such that the `step()` method (and consequently `run()`) must propagate uncaught exceptions that occur in processes. This allows the caller to control the way exceptions are handled.

|
This change fixes a bug where a process would be resumed again after it
had crashed, bringing down the kernel.
Fixes #27

|
This change in Instrumentation API allows the user to close the data
stream of an instrument by introducing a new concept: Port. A user can
open a `Port` for a `Simulation` object and attach an arbitrary amount of
instruments to this port. The data streams are closed by calling
`Port#close()`.
|
|
These changes implement the Instrumentation API described in issue #11
into the Omega simulation kernel.
|
|
This change simplifies the `Context` interface to reduce the amount of
methods required to implement by implementors.
|
|
This change removes the unused transformation receive methods from the
`Context` class as this functionality can now be easily implemented in
the standard library using the newly introduced `sender` property.
|
|
This change fixes the bug where the insertion order into the message
queue was not guaranteed for messages arriving at the same time, causing
some non-deterministic behaviour.
|
|
|
|
This change provides a method in the standard library to access the
process context in nested suspending function calls.
|
|
This change adds a `sender` property to the `Context` interface to
provide processes access to the sender of the latest received message.
Please note that methods like `hold()` and `interrupt()` may change the value
of this property.
|
|
This change fixes the broken implementation of the `receive()` method
with a timeout due to an invalid condition.
|
|
This change will make the kernel handle the launch of processes using a
kernel process that is launched at the start of the simulation and
launches processes when it receives `Launch` messages.
|
|
This change creates a distinction between a kernel and a simulation.
A single simulation is represented by a `Simulation` object which
provides control over the simulation, while the `Kernel` interface
allows users to create a new simulation using that kernel as backend.
|
|
This change fixes the deployment of the OpenDC simulation model.
|
|
This change will make the simulation kernel launch the processes at the
initial run instead of when the processes are registered.
|
|
This change aligns the code formatting of the project with the official
Kotlin Style Guide. They can be found at
http://kotlinlang.org/docs/reference/coding-conventions.html.
|
|
This change contains the redesign of the core simulation API and
provides a cleaner interface for developing simulation models for the
users.
