2022-11-13refactor: Replace use of CoroutineContext by DispatcherFabian Mastenbroek
This change replaces the use of `CoroutineContext` for passing the `SimulationDispatcher` across the different modules of OpenDC by the lightweight `Dispatcher` interface of the OpenDC common module.
2022-11-13refactor(sim/core): Re-implement SimulationScheduler as DispatcherFabian Mastenbroek
This change updates the `SimulationScheduler` class to implement the `Dispatcher` interface from the OpenDC Common module, so that OpenDC modules only need to depend on the common module for dispatching future task (possibly in simulation).
2022-11-13refactor: Use InstantSource as time sourceFabian Mastenbroek
This change updates the modules of OpenDC to always accept the `InstantSource` interface as source of time. Previously we used `java.time.Clock`, but this class is bound to a time zone which does not make sense for our use-cases. Since `java.time.Clock` implements `java.time.InstantSource`, it can be used in places that require an `InstantSource` as parameter. Conversion from `InstantSource` to `Clock` is also possible by invoking `InstantSource#withZone`.
2022-11-13feat(common): Add compatibility with Kotlin coroutinesFabian Mastenbroek
This change adds support for converting a `Dispatcher` implementation into a `CoroutineDispatcher` instance.
2022-11-09feat(common): Add common dispatcher interfaceFabian Mastenbroek
This change adds a new interface `Dispatcher` that is used throughout OpenDC for scheduling the execution of future tasks. This replaces the `CoroutineContext` and `Clock` that exist on many of the implementations in OpenDC. With this approach, we reduce the dependency on Kotlin Coroutines.
2022-10-06build: Switch to Spotless for formattingFabian Mastenbroek
This change updates the build configuration to use Spotless for code formating of both Kotlin and Java.
2022-10-06style: Eliminate use of wildcard importsFabian Mastenbroek
This change updates the repository to remove the use of wildcard imports everywhere. Wildcard imports are not allowed by default by Ktlint as well as Google's Java style guide.
2022-10-05refactor(sim/core): Rename runBlockingSimulation to runSimulationFabian Mastenbroek
This change renames the method `runBlockingSimulation` to `runSimulation` to put more emphasis on the simulation part of the method. The blocking part is not that important, but this behavior is still described in the method documentation.
2022-10-05refactor(sim/core): Use SimulationScheduler in coroutine dispatcherFabian Mastenbroek
This change updates the implementation of `SimulationDispatcher` to use a (possibly user-provided) `SimulationScheduler` for managing the execution of the simulation and future tasks.
2022-05-18build: Use correct group for Gradle modulesFabian Mastenbroek
2022-04-23build: Enable testing for all library modulesFabian Mastenbroek
This change updates the Gradle build configuration to ensure that all library modules (that will be published) use testing and are included in coverage reports. This should ensure the public modules remain well tested.
2022-02-18build: Remove opendc-platform moduleFabian Mastenbroek
This change removes the opendc-platform module from the project. This module represented a Java platform which was previously used for sharing a set of dependency versions between subprojects. However, with the version catalogue that was added by Gradle, we currently do not use the platform anymore.
2022-02-18perf(common): Optimize TimerSchedulerFabian Mastenbroek
This change updates the TimerScheduler implementation to directly use the Delay object instead of running the timers inside a coroutine. Constructing the coroutine is more expensive, so we prefer running in a Runnable.
2022-02-18refactor(utils): Rename utils module to common moduleFabian Mastenbroek
This change adds a new module, opendc-common, that contains functionality that is shared across OpenDC's modules. We move the existing utils module into this new module.
