RunExecutableListener always waits for the subprocess completion regardless of
wait="false"
-------------------------------------------------------------------------------------------
Key: SOLR-198
URL: https://issues.apache.org/jira/browse/SOLR-198
Project: Solr
Issue Type: Bug
Reporter: Koji Sekiguchi
Priority: Minor
Although the type of the value of "wait" attribute is boolean in solrconfig.xml:
<listener event="postCommit" class="solr.RunExecutableListener">
<str name="exe">snapshooter</str>
<str name="dir">solr/bin</str>
<bool name="wait">false</bool>
<arr name="args"> <str>arg1</str> <str>arg2</str> </arr>
<arr name="env"> <str>MYVAR=val1</str> </arr>
</listener>
RunExecutableListener trys to get the value as a string:
if ("false".equals(args.get("wait"))) wait=false;
therefore, it always waits for the subprocess completion, even if you set
wait="false" . The above line would probably be like this:
if (Boolean.FALSE.equals(args.get("wait"))) wait=false;
