--------------------------------------
Summary: Document pitfalls of the installer-provider-installhook
Key: SLING-9502
URL: https://issues.apache.org/jira/browse/SLING-9502
Project: Sling
Issue Type: Improvement
Components: Installer
Affects Versions: Installer Vault Package Install Hook 1.1.0
Reporter: Konrad Windszus
The page at
[https://sling.apache.org/documentation/bundles/installer-provider-installhook.html]
should outline that a synchronous deployment of bundles comes also with some
drawbacks which is why https://issues.apache.org/jira/browse/SLING-3747 has
been added in the first place.
For example the composum package manager
([https://github.com/ist-dresden/composum/blob/develop/sling/core/pckgmgr/src/main/java/com/composum/sling/core/pckgmgr/PackageJobExecutor.java#L226])
depends on the Sling Dynamic Class Loader which might restart after a bundle
deployment. Further information about that in
[https://lists.apache.org/thread.html/57d56e31da3c1cb743cf524e0c85e46959f3af9ed946f2c4a41d33c0@%3Cdev.sling.apache.org%3E].
Those pitfalls should be documented at
[https://sling.apache.org/documentation/bundles/installer-provider-installhook.html]
to make clear that this hook is not the silver bullet.
