A. J. David Bosschaert commented on FELIX-6384: ----------------------------------------------- Merged with many thanks [~kwin]! > Felix Configadmin Interpolator: Support default directive with empty value > -------------------------------------------------------------------------- > > Key: FELIX-6384 > URL: https://issues.apache.org/jira/browse/FELIX-6384 > Project: Felix > Issue Type: Improvement > Components: Configuration Admin > Affects Versions: configadmin-interpolation-plugin-1.1.0 > Reporter: Konrad Windszus > Priority: Major > > Currently in > https://github.com/apache/felix-dev/tree/master/configadmin-plugins/interpolation#default-values > it is not stated that an empty value is not supported as default value. > Still the following code is not replaced as expected > {code} > $[env:NON_EXISTING_VAR;default=] > {code} > This is due to the parsing logic in > https://github.com/apache/felix-dev/blob/0aa232a4ff8f95e92d947027ac7d8010e2a0e142/configadmin-plugins/interpolation/src/main/java/org/apache/felix/configadmin/plugin/interpolation/Interpolator.java#L118 > which detects the directive (in this case {{default}}) only in case there is > at least one character after the {{=}}. > This limitation should be lifted to also allow empty values as default > values. At the same time values containing the character {{=}} should be > allowed as well. -- This message was sent by Atlassian Jira (v8.3.4#803005)
