------------------------------------------
Summary: Executing feature:repo-remove can leave karaf in an
invalid state
Key: KARAF-5123
URL: https://issues.apache.org/jira/browse/KARAF-5123
Project: Karaf
Issue Type: Bug
Components: karaf-feature
Affects Versions: 4.1.1
Reporter: Christian Schneider
Assignee: Christian Schneider
Fix For: 4.2.0, 4.1.2
To reproduce:
feature:repo-add activemq 5.14.5
feature:install activemq-client
feature:repo-remove activemq-5.14.5
# After this step karaf is in an invalid state but no error / warning is shown
feature:install jdbc
Error executing command: Unable to resolve root: missing requirement [root]
osgi.identity; osgi.identity=activemq-client; type=karaf.feature;
version="[5.14.5,5.14.5]";
filter:="(&(osgi.identity=activemq-client)(type=karaf.feature)(version>=5.14.5)(version<=5.14.5))"
When installing any other feature karaf complains about the feature
activemq-client as it knowns it should be installed but does not find the repo
anymore.
The workaround is to remove all features that are now not available anymore in
one step. Removing individually does not work if there are more than one
feature missing as feature:uninstall is only executed if it leaves karaf in a
valid state.
I propose we these things:
- At least we need to provide a warning when executing feature:repo-remove and
list all features that are now unavailable.
- Even better would be to refuse to remove the repo when some of its features
are still needed. Eventually we want an override like -f to force removal.
