Improve PeridodicSchedulerImplTest (#2856)
* Improve PeridodicSchedulerImplTest

The old implementation truncated timestamps to 1/10 s. Under some circumstances this could result in a failed tests:

offset = 201 -> truncatedOffset = 2
200ms delay expected, adjustment calculation results in an actual delay of 198ms
time = 399 -> truncatedTime = 3

expected: truncatedOffset + expected => 2 + 2 = 4
actual: truncatedTime = 3

The new implementation allows for an error of +/- 10ms which is far more than needed.

* increase tolerance
* fix consecutive executions build up errors

openHAB Core

GitHub Actions Build Status Jenkins Build Status EPL-2.0 Crowdin Bountysource

This project contains core bundles of the openHAB runtime.

Building and running the project is fairly easy if you follow the steps detailed below.

Please note that openHAB Core is not a product itself, but a framework to build solutions on top. It is picked up by the main openHAB distribution.

This means that what you build is primarily an artifact repository of OSGi bundles that can be used within smart home products.

1. Prerequisites

The build infrastructure is based on Maven. If you know Maven already then there won't be any surprises for you. If you have not worked with Maven yet, just follow the instructions and everything will miraculously work ;-)

What you need before you start:

Make sure that the mvn command is available on your path

2. Checkout

Checkout the source code from GitHub, e.g. by running:

git clone https://github.com/openhab/openhab-core.git

3. Building with Maven

To build this project from the sources, Maven takes care of everything:

  • set MAVEN_OPTS to -Xms512m -Xmx1024m
  • change into the openhab-core directory (cd openhab-core)
  • run mvn clean install to compile and package all sources

If there are tests that are failing occasionally on your local build, run mvn -DskipTests=true clean install instead to skip them.

How to contribute

If you want to become a contributor to the project, please read about contributing and check our guidelines first.
