Re: Reference of local service.
Andrey, IgniteServices.service() method could return actual interface implementation instead of interface itself. IgniteServices.service() always return actual local service instance, no proxy, might be without any interface but except Service. If yes then we can add new method IgniteService.serviceLocalProxy(). It will not break backward compatibility and will always return proxy. Why not using IgniteServices.serviceProxy() for that? Since it requires an interface, It could return proxy for local service too and keep backward compatibility at the same time. 16.03.2020 20:21, Andrey Gura пишет: Vladimir, We won’t affect existing services How exactly will we affect services without special interface? Please see the benchmarks in previous email. I talk about backward compatibility, not about performance. But it doesn't matter because... see below. My fault. From discussion I realized that services doesn't require interface. But indeed it does require. If I understand correctly, IgniteServices.service() method could return actual interface implementation instead of interface itself. Am I right? If yes then we can add new method IgniteService.serviceLocalProxy(). It will not break backward compatibility and will always return proxy.

Please see the benchmarks in previous email. what if we generate will generate proxy that collects service’s metrics only if service will implement some special interface? I don’t like idea enabling/disabling metrics involves code change, compilation. I believe it should be an external option, probably available at runtime through JMX. we can impose additional requirement for services that want use metrics out of box. … service must have own interface and only invocations of methods of this interface will be taken into account for metrics collection. Why one more interface? To work via proxy, with remote services user already has to use an interface additionally to Service. If we introduce proxy for local services too (as suggested earlier), an interface will be required. Current IgniteService#serviceProxy() already requires interface even for local service. I don’t think we need one more special interface. user always can use own metrics framework. Since we do not significantly affect services user can use both or disable our by an option. With the discussion before and the benchmark I propose: - Let IgniteService#serviceProxy() give GridServiceProxy for local services too. It already requires to work via interface. So it’s safe for user code. - Deprecate IgniteService#service() - Make service metrics enabled by default for all services. - Bring system param which disables metrics by default for all services. - Bring parameter/method in MetricsMxBean which allows disabling/enabling metrics for all services at run time. Makes sense? чт, 5 мар. 2020 г., 16:48 Andrey Gura : Hi there, what if we will generate proxy that collects service's metrics only if service will implement some special interface? In such case: - we won't affect existing services at all. - we can impose additional requirement for services that want use metrics out of box (i.e. service that implements our special interface *must* also have own interface and only invocations of methods of this interface will be taken into account for metrics collection). - user always can use own metrics framework instead of our (just do not implement this new special interface). About metrics enabling/disabling. At present IGNITE-11927 doesn't solve this problem. Just because there is no metrics implementation for services :) Anyway we should provide a way for configuring service metrics (in sense of enabled/disabled) during service deploy. It's easy for cases where deploy() methods have ServiceConfiguration as parameter. But there are "short cut" methods like deployXxxSingleton(). I have ideas how to solve this problem. For example we can introduce "short cut" factory methods like nodeSingletonConfiguration(String name, Service service) and clusterSingletonConfiguration(String name, Service service). This methods will return configuration which has parameters for given type of deployment and could be modified, e.g. metrics could be enabled. WDYT?

That looks safe for user code. Doing so we might only deprecate IgniteService#

deadlock in system pool on meta update
Classification: Public Hi, I've recently tried to apply Ilya's idea (https://issues.apache.org/jira/browse/IGNITE-12663) of minimizing thread pools and tried to set system pool to 3 in my own tests. It caused deadlock on a client node and I think it can happen not only on such small pool values. Details are following: I'm not using persistence currently (if it matters). On the client note I use ignite compute to call a job on every server node (there are 3 server nodes in the tests). Then I've found in logs: [10:55:21] : [Step 1/1] [2020-03-13 10:55:21,773] { grid-timeout-worker-#8} [WARN] [o.a.i.i.IgniteKernal] - Possible thread pool starvation detected (no task completed in last 3ms, is system thread pool size large enough?)

Re: [DISCUSSION] Changes in Ignite release process related to documentation
Denis, I agree with you. Also I think that we should move to process which will require documentation updates during work on issue/feature and will part of code review process. Such approach has some useful benefits: - Documentation readiness at the same time when fix/implementation is ready (remember, documentation is part of a product). - Work on documentation and review could discover incompleteness of a fix or a feature on earlier stage (It is usual situation when some aspects were just forgotten, but documentation writing could spotlight such things).

[jira] [Created] (IGNITE-12791) [IEP-39] Management API to cancel user provided tasks and queries - documentation
Nikolay Izhikov created IGNITE-12791: Summary: [IEP-39] Management API to cancel user provided tasks and queries - documentation Key: IGNITE-12791 URL: https://issues.apache.org/jira/browse/IGNITE-12791 Project: Ignite Issue Type: Improvement Reporter: Nikolay Izhikov Assignee: Nikolay Izhikov Ignite provides many API to deploy and execute user-provided code on the server nodes inside the same JVM as the Ignite process runs. Ignite has many APIs that allocate many resources on the server nodes, also. In case of some buggy code that consumes many system resources(CPU, RAM, flood network) or heavy query the whole cluster can become unstable. We should provide to the cluster administrator the ability to stop any user deployed task. JMX beans to cancel listed tasks should be introduced: * Compute task * Service * Continuous query * Transactions * Queries(SQL, Scan, Text) In the scope of IEP-35 System view API introduced. A new API should use the same identifier that is used in corresponding System View. -- This message was sent by Atlassian Jira (v8.3.4#803005)

Re: [DISCUSSION] Changes in Ignite release process related to documentation
Hi Denis, My suggestion is that in the current version release process, when planning to release a version, first determine the Time, Scope and ReleaseManager. On this basis, we can add another work of documentation, which is to determine which documents need to be written and who should write them,instead of adding documents after all the work is done. 在 2020/3/13 上午12:49, Denis Magda 写道: Igniters, With the final 2.8 release steps checked out today by announcing the version globally (congrats!), it's a proper time to consider and tweak our release process, making completion of some phases more predictable and aligned. I would like to dedicate this thread solely to changes related to the documentation. If to do a recap, Ignite 2.8 announcement went out of sync with the publication of binaries, Maven and other artifacts because our technical documentation was completed long after the vote had been closed. We can easily eliminate such glitches for future releases if agree to start a vote only if Ignite docs are ready and can be published the same day with other release artifacts. If the docs are completed and available internally while the vote goes then we can work on a release blog post (referring to docs details) and announce the release the same day when the binaries/docs availability. Thoughts? Let's change the process ensuring that the vote can be started only if technical documentation is ready to be released? - Denis
Re: Apache Ignite 2.8.1 RELEASE [Time, Scope, Manager]
Folks, I've walked through all the commits to master since 2.8 branch was cut and filtered some tickets that in my opinion are worth including to 2.8.1 release below (note that they are ready end the effort of including them to the release should be low as long as there are no implicit dependencies between tickets).

Re: Security Subject of thin client on remote nodes
Hello, Alexei! I agree with you if we may not care about compatibility at all, then we can solve the problem much more straightforward way. In your case, the method GridSecurityProcessor#authenticate will have an implicit contract: [ if actx.subject() != null then returns SecurityContext else do authenticate ] It looks fragile. When we extend the GridSecurityProcessor, there isn't this problem: we have the explicit contract and can make default implementation that throws an unsupported operation exception to enforcing compatibility check. In any case, we need to change GridSecurityProcessor implementation. But I think your proposal to try to find a security context in the node's attributes first is right for backward compatibility when Ignite users don't use thin clients. Summary: I suggest adding a new method to GridSecurityProcessor because it has a clear contract and enforces compatibility check natural way. вс, 15 мар. 2020 г. в 17:13, Alexei Scherbakov : > Denis Garus, > > I've looked at the IEP proposed by you and currently I'm thinking it's not > immediately required. > > The problem of missing SecurityContexts of thin clients can be solved much > easily. > > Below is the stub of a fix, it requires correct implementation of > method > org.apache.ignite.internal.processors.security.IgniteSecurityProcessor#authenticatedSubject > by GridSecurityProcessor: > > /** {@inheritDoc} */ > @Override public OperationSecurityContext withContext(UUID nodeId) { > try { > SecurityContext ctx0 = secCtxs.get(nodeId); > > if (ctx0 == null) { > ClusterNode node = > Optional.ofNullable(ctx.discovery().node(nodeId)) > .orElseGet(() -> > ctx.discovery().historicalNode(nodeId)); > > // This is a cluster node. > if (node != null) > ctx0 = nodeSecurityContext(marsh, > U.resolveClassLoader(ctx.config()), findNode(nodeId)); > else { > // This is already authenticated thin client. > SecuritySubject subj = authenticatedSubject(nodeId); > > assert subj != null : "Subject is null " + nodeId; > > AuthenticationContext actx = new > AuthenticationContext(); > actx.subject(subj); > > ctx0 = secPrc.authenticate(actx); > } > } > > secCtxs.putIfAbsent(nodeId, ctx0); > > return withContext(ctx0); > } catch (IgniteCheckedException e) { > throw new IgniteException(e); > } > > The idea is to create a thin client SecurityContext on a node not having a > local context using existing SecuritySubject data. > > Method > org.apache.ignite.internal.processors.security.GridSecurityProcessor#authenticate > should check for not null SecuritySubject field and just recreate > SecurityContext using passed info (because it's already authenticated). > > We have all necessary information in SecuritySubject returned by > > org.apache.ignite.internal.processors.security.IgniteSecurityProcessor#authenticatedSubject > by GridSecurityProcessor method. > > Because it is internal API, we may not care about compatibility at all, > but nevertheless it is possible to add compatibility check in the method > above.
