Charles E. Rolke created DISPATCH-1707:
------------------------------------------
Summary: Policy config file fails with cryptic error if trailing
brace on wrong line
Key: DISPATCH-1707
URL: https://issues.apache.org/jira/browse/DISPATCH-1707
Project: Qpid Dispatch
Issue Type: Bug
Components: Management Agent, Policy Engine
Affects Versions: 1.12.0
Reporter: Charles E. Rolke
If a policy vhost in a config file is specified like this
{code:java}
vhost {
hostname: 0.0.0.0
allowUnknownUser: true
groups: {
"$default": {
"users": "*",
"remoteHosts": "*",
"allowDynamicSource": true,
"allowAnonymousSender": true,
"sources": "*",
"targets": "*"}
}
}
{code}
then it works fine. Buf if the trailing brace after _targets_ is on a line by
itself
{code:java}
vhost {
hostname: 0.0.0.0
allowUnknownUser: true
groups: {
"$default": {
"users": "*",
"remoteHosts": "*",
"allowDynamicSource": true,
"allowAnonymousSender": true,
"sources": "*",
"targets": "*"
}
}
}
{code}
then it fails with a confusing message that does not pinpoint what is wrong.
{code:java}
