Subject [jira] Commented: (DERBY-1063) Add new jar file to execute tools/network server with java -jar
Date Fri, 10 Mar 2006 08:34:45 GMT
    [ http://issues.apache.org/jira/browse/DERBY-1063?page=comments#action_12369823 ] 

Andrew McIntyre commented on DERBY-1063:

I've thought a bit about how to test this. It would involve getting the location of the derbyrun.jar
by using getResource for org.apache.derby.iapi.tools.run, then forking a JVM to run java -jar
for each of the tools launched by the run class, and then capturing the output of the corresponding
usage messages.  One problem is that, unlike the other tools, ij doesn't have a usage message.
We could Process.destroy() the ij instance after creating it, but there's two problems with
that: Process.destroy() isn't (or at least, historically hasn't  been) very reliable and the
version string is included in ij's startup text. The version could be filtered out, I suppose,
but the reliability of Process.destroy() is more problematic. I'd rather not leave zombie
processes in test environments due to using Runtime.exec(). If ij had a usage message, then
it wouldn't be a problem. I could add a usage message to ij, in conjunction with writing such
a test.

I'm certainly open to any other good ideas for how to test the run class. Let me know if you
have any.

Originally added as part of DERBY-1019, this seeks to reinstate thee functonality that was
removed as a result of DERBY-1045. Create a new jar file to execute the tools, along with
an improvement to sysinfo to report the location of the jars from which the info properties
files are loaded. Note that this does not attempt to mitigate the current problems running
sysinfo under a security manager, but to improve the reporting of the locations of the loaded
files if they are not loaded from the classpath.
