Pierre De Rop commented on FELIX-3680:
--------------------------------------
I have updated what I committed yesterday in order to use only static/required
References in A.
Now I'm thinking about the following, and wonder if it is related to what you
observed:
I realize that that when disabling components, then the disable task (that is:
ComponentContext.disable method call) is done asynchronously (using the
component actor thread).
Am I correct ? (I think you already explained this but I did not catch it ...
sorry).
So, it is then possible that when the Main.unbind method is called, then the
_disableLatch.countDown() is called while some disable tasks are not yet
executed and still scheduled in the component actor thread. At this point, the
Main.run method is then unblocked form the _disableLatch, and then try to
re-enable components ... while the previous disable tasks are not yet executed
by the component actor thread. However, since enable tasks are also scheduled
in the component actor thread queue, then all pending disable tasks should be
executed before the new enable tasks ...
I now start to understand why you asked me to try the (not yet committed)
ScrService.waitForTasksCompleted.
So, did you try to use your ScrService.waitForTasksCompleted() method from the
standalone version ?

> Key: FELIX-3680
> URL: https://issues.apache.org/jira/browse/FELIX-3680
> Project: Felix
> Issue Type: Bug
> Components: Declarative Services (SCR)
> Environment: linux fc16, jdk1.6.032
> Reporter: Pierre De Rop
> Attachments: logs_with_could_not_get_service_from_ref.txt.gz,
> test.scr.tgz, test_with_fwk.tgz

> This issue contains a sample code which reproduces many various exceptions,
> using a concurrent
> scenario, where some services are enabled/disabled concurrently.
> I did not have time to commit an integration test about these exceptions but
> I will try to do.
> In the meantime, I join to this issue my scenario ...
> Before trying to make an integration test, could you please run the scenario,
> in order to confirm the problems, and that the scenario is valid ?
> To execute the scenario
> 1) first, since the framework is not currently using any available log
> service, you have to make a modification in the framework, in order to force
> the framework to use a log service, when displaying caught exceptions. If you
> don't do this, then you will get many exceptions thrown by many threads and
> displayed in the console; and this is then not easy to diagnose problems.
> So, in the framework, in the file
> src/main/java/org/apache/felix/framework/Logger.java, in method
> setBundleContext, just uncomment the following code, which activate the fwk
> log service listener:
> protected void setSystemBundleContext(BundleContext context)
> {
> // TODO: Find a way to log to a log service inside the framework.
> // The issue is that we log messages while holding framework
> // internal locks -- hence, when a log service calls back into
> // the framework (e.g., by loading a class) we might deadlock.
> // One instance of this problem is tracked in FELIX-536.
> // For now we just disable logging to log services inside the
> // framework.
> m_context = context;
> startListeningForLogService();
> }
> -> this will make sure all logs caught by the framework are redirected to the
> log service, and I did not find any deadlock issue, as described in the
> comments.
> Notice that even if you don't activate the log service listener, then the
> Exceptions are also taking place ...
> 2) next, compile the attached concurrent scenario (it's a simple maven
> project).
> 3) run the framework with the following bundles:
> org.apache.felix.scr from trunk
> org.apache.felix.configadmin-1.4.0.jar
> 4) wait for about 20 seconds, then suspend the framework, and kill it (using
> kill -9)
> Don't do "Ctrl-C", because this might interrupt some locked threads and some
> exceptions might be generated because of the Ctlr-C ... So doing a "Kill -9"
> is better.
> 5) Then take a look at the produced "./logs.txt" file.
> scenario description:
> ===============
> here is a description of the Components used in the scenario:
> A: delayed component, enabled, depending on B,C,D,E,F
> B,C,D,E: delayed components, disabled, without any dependencies
> F: delayed component, disabled, depending on G
> G: delayed component, disabled, depending on H
> I: delayed component, disabled, depending on J
> J: delayed component, disabled, depending on K
> Main: depends on A.
> "Main" is the main scenario component: it uses a thread pool in order to
> enable B,C,D,E,F,G,H,I,J,K in parallel, randomly.
> "Main" depends on A.
> When B,C,D,E,F,G,H,I,J,K are enabled, then A becomes satisfied, provided and
> injected in the "Main" component.
> Once "A" is bound to "Main", then B,C,D,E,F,G,H,I,J,K are then disabled in
> parallel, randomly. "Main" also checks that "A" is properly unbound.
> LogService logs are written to "./logs.txt".
> So, running the test using scr 1.6.0 runs seamlessly. But with trunk we have
> many various exceptions.
> For example, I have noticed the three following exceptions:
> 1) we have some IllegalMontorStateException:
