Subject [jira] [Updated] (DERBY-5819) Add logic to BaseTestCase to start subprocesses ready to be attached to from a Java debugger
Date Sat, 23 Jun 2012 01:47:42 GMT

     [ https://issues.apache.org/jira/browse/DERBY-5819?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Dag H. Wanvik updated DERBY-5819:
---------------------------------

    Attachment: derby-5819d.diff

Added an other option to control the way the subprocesses are started:

derby.test.debugSuspend=<y|n> default 'y'

Unless this property is 'n', the subprocess will hang till the debugger is connected, cf the
explanation here:

> Sometimes it's useful to be able to attach to subprocesses of tests with a debugger.
> Now that we have centralized subprocess creation in BaseTestCase#execJavaCmd it would
be easy and useful to have subprocesses start, but wait for a debugger to attach to them,
i.e. with these options on an Oracle VM:
> -Xdebug -Xrunjdwp:transport=dt_socket,address=<port>,server=y,suspend=y
