Subject [jira] [Updated] (DERBY-5444) SpawnedProcess.complete may fail to destroy the process when a timeout is specified
Date Wed, 05 Oct 2011 20:14:29 GMT

     [ https://issues.apache.org/jira/browse/DERBY-5444?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kristian Waagan updated DERBY-5444:
-----------------------------------

    Attachment: derby-5444-1b-destroy_on_timeout.diff

Patch 1b changes how InterruptedExceptions are handled; they are now either ignored (because
it doesn't matter for SpawnedProcess), or an exception is raised.

Running regressions now.
Patch ready for review.

> The logic in SpawnedProcess has a weakness that may result in the wrapped process not
being destroyed if the destroy variable is false and a timeout is specified.
> The problem is that the while condition will shortcut the if condition in the catch clause
(where destroy is set to true if the timeout is exceeded).
