Description Philippe Mouawad 2013-05-09 14:36:29 UTC
Necessary to avoid losing test data if kill or CTRL+C are called with the following setting (available since JMETER 2.10)

Draft of patch

Attached is a first proposal of Shutdown Hook implementation.
I had to add a join on StopThread otherwise it can happen exit occurs before thread is started.

Anyway there is still an issue as if shutodwn of threads takes more than jmeterengine.threadstop.wait (ThreadGroup#WAIT_TO_DIE) then it can happen that close will not be called on PrintWriter.

Note: the code in 2.9 and before used autoflush = true
Comment 3 Sebb 2013-05-09 16:13:30 UTC
Note that the shutdown hook is run even if JMeter shuts down normally.
In which case it should not call engine.stop(true).

I wonder if it would be better to implement the shutdown hook in ResultCollector instead.

That might avoid some of the problems?
