Maven Central License Build Status

ebx-shutdown-sdk

Listening for and responding gracefully to application shutdown is common boilerplate. Whilst it's possible for applications to directly monitor for SIGTERM signals:

Runtime.getRuntime().addShutdownHook(new Thread(() -> { ...

experience has shown it only takes one dependency to do this incorrectly for the entire application to close ungracefully. This SDK intends to provide an alternative way of guaranteeing graceful shutdowns.

  • ShutdownMonitor is an interface for requesting a shutdown, setShutdownRequested, and checking for if a shutdown has been requested, isShutdownRequested.
  • ShutdownRequestedException is provided as an optional way for handling resource cleanup during shutdown.

Implementations included are:

  • SimpleShutdownMonitor - Supports manual triggering only.
  • WatchingShutdownMonitor (and WatchingShutdownMonitor.Builder) - Extends SimpleShutdownMonitor. Can also be configured to listen for a shutdown file (listenForShutdownFile) and SIGTERM (registerShutdownHook).

Releases

We use semantic versioning.

All merges into DEV will automatically get released as a maven central snapshot, which can be easily included in any downstream dependencies that always desire the latest changes (see above for 'Most Up To Date' installation).

Each merge into the MASTER branch will automatically get released to Maven central and github releases, using the current library version. As such, following every merge to master, the version number of the dev branch should be incremented and will represent 'Work In Progress' towards the next release.

Please use a merge (not rebase) commit when merging dev into master to perform the release.

To create a full release to Maven central please follow these steps:

  1. Ensure the CHANGELOG.md is up to date with all the changes in the release, if not please raise a suitable PR into DEV. Typically the change log should be updated as we go.
  2. Create a PR from DEV into MASTER. Ensure the version in the pom.xml is the correct version to be released. Merging this PR into MASTER will automatically create the maven and github releases. Please note that a release is final, it can not be undone/deleted/overwritten.
  3. Once the public release has been successful create a final PR into DEV that contains an incremented pom.xml version to ensure the correct snapshot gets updated on subsequent merges into DEV. This PR should also include:
    • An update to the README.md latest stable release version number.
    • A 'Work In Progress' entry for the next anticipated release in CHANGELOG.md.
