Re: [Dev] C5- Datasource startup order issue

[Himasha Guruge]

Hi Sameera,

Thanks for the provided info.In bpmn component   to  build  activiti
engine, we require the datasource bundle to be available. Therefore we
tried adding  @Reference annotation  of
org.wso2.carbon.kernel.datasource.core.internal.DataSourceListenerComponent
(for activate method of ActivitiEngineBuilder) but this did not work.

 AFAIU what you suggest is to implement a Listener class that would contain
onJNDIReady() method, which would require other bundles(activiti bundle in
this case) to wait until this method is executed.  Could you please provide
any suggestions on this?

Regards,

Re: [Dev] Annotations are not processed correctly with maven-bundle-plugin 3.0.1 version

Hi Aruna,

Let's contact maven-bundle plugin mailing list and bndtools github project
and check with them first on this. bndtools is the internal lib used with
processing ds_annotations in bundles.

 Hi,

 Currently when building the wso2 docker images [1], we are not
 prompting the complete image building logs [2], we are only prompting if
 there is any error while building.

 Is there any specific reason for not prompting the complete log trace

 Isn't it better to show the complete build logs or at least an option
 for user to see the complete logs? Thoughts?

[Dev] [dev][BAM] Format of the Row_ID in EVENT_KS : bam_mediation_stats_data_publisher table

[Hasanthi Purnima Dissanayake]

Hi All,

In EVENT_KS : bam_mediation_stats_data_publisher table the primary key is
(Row_ID) a composite key.
E.g : 1457935867059::127.0.0.1::9443::2448
Can someone please explain me the format of this key. Is it Timestamp :: IP
address :: Port :: Random Number?

Any feedback is highly appreciated.

[Dev] Annotations are not processed correctly with maven-bundle-plugin 3.0.1 version

[Aruna Karunarathna]

Hi all,

With the upgrade of wso2 parent pom version 3, the maven-bundle-plugin
version is upgraded to 3.0.1.

The property annotation inside the Component are not being added to the
Manifest headers with this new version. See the below example.

@Component(
name =
"org.wso2.carbon.kernel.internal.deployment.DeploymentEngineListenerComponent",
immediate = true,



*property = {
"capability-name=org.wso2.carbon.kernel.deployment.Deployer",
"component-key=carbon-deployment-service"}*
)

for the 2.5.4 version's generated MANIFEST.MF I could see the following in
Provide-Capability section.

Provide-Capability: osgi.service;effective:=active;objectClass="org.wso2
 .carbon.kernel.startupresolver.RequiredCapabilityListener";

*capability-n
 ame="org.wso2.carbon.sample.deployer.mgt.Deployer";component-key=carbon
 -sample-deployment-engine*

And for the 3.0.1 version's generated MANIFEST.MF I could see the following
in Provide-Capability section. the property tag inside the Component
annotation is missing.

Provide-Capability: osgi.service;objectClass:List="org.wso2.carb
 on.kernel.startupresolver.RequiredCapabilityListener"

Also the objectClass is changed to objectClass:List.

Regards,
Aruna

[Dev] C5- Datasource startup order issue

Hi Sameera,

With regards to $subject, so far we have used the workaround of manually
renaming the bundle's symbolic name which works perfectly. However is it
possible to know when this fix will be available?

Re: [Dev] WSO2 Dockerfiles build logs

[Chamila De Alwis]

Hi Vishanth, Imesh,

This was introduced to keep the output of the build script to the minimum
and to exit with a proper code if the docker build command fails. If the
puppet run fails, the docker build command does not fail, as it does not
seem to exit with a non-zero code. Therefore, it was necessary to grep for
any "error" outputs and exit accordingly.

However I see your point about being verbose when it comes to the build.
I'm testing a -q flag for the build script which if used, will suppress the
output and only show any errors. I will push the changes soon.

Re: [Dev] Gsoc Project proposal 21

[Tharindu Edirisinghe]

Hi Asantha,

Great work ! We will check the source code and provide you feedback soon.
Regarding implementing the interface rather than extending the
JDBCUserStoreManager class... yes here we can and have to implement all the
methods from the scratch because we won't be be able to reuse any code used
in RDBMSs. As you progress through the project, write your experiences in a
blog too...

Thanks,
TharinduE

[Dev] Fwd: GSoC 2016- Contact Development Team feature in DevStudio.

Hello Nathiesha

Please see my inline comments ,

Good to hear that you have familiar with all basic eclipse plugin type and
development  process ,

NO , Developer Studio is not a RCP  , we develop general eclipse
plugins/features and install those into the  eclipse , Actually Developer
studio is a set of plugin/features installed on top of eclipse IDE

 So there is no different , we use vanilla Eclipse IDE to installed our
features

Yes very much same functionalities , but if you come across more valuable
 functionalities please discuss here

Yes your understanding is correct , but contact details should be
configurable  because it won't be always wso2 support portal

Could you please come-up with the high level architecture diagram for this
feature ?


PS : It's very important to keep visibility in open source community  so
don't send private mails, always copy @dev list as well.

for your feedback to continue the user store development,
Now i'm in the stage of developing the database architecture for mongodb
and i will soon update all my works done so far in my blog

 Hi Osura,

 It's nice to hear your interest on this project. The starting point
 would be to install Mesos and see how it works. Then try to deploy a WSO2
 product on Mesos using Docker. Then understand how Carbon clustering works
 including K8S membership scheme [1] we have implemented for the same
 purpose on K8S. Later on move to other native PaaS features needed.

Re: [Dev] WSO2 Dockerfiles build logs

IMO it is important to show the docker build command output to the user.
Otherwise it would be difficult for the user to understand what's happening

[Dev] Common configuration for publishing events from carbon servers to DAS/CEP

[Malith Dhanushka]

Hi all,

Please follow the steps bellow when publishing events from carbon servers
to DAS/CEP. Here we keep the DAS/CEP server location in
CARBON_HOME/repository/deployment/server/eventpublishers directory and this
is common across platform.

- Install the Event Publisher Aggregate feature from p2_repo [1]

- Install Registry Core feature if not installed

- Create event stream and deploy that to
CARBON_HOME/repository/deployment/server/eventstreams

- Create publishers for the created stream and deploy that to
 CARBON_HOME/repository/deployment/server/eventpublishers
Following is a sample configuration,


http://wso2.org/carbon/eventpublisher;>
  
  
  
admin
thrift
non-blocking
0
tcp://localhost:7611
X
  


- Publish events to the created stream using
org.wso2.carbon.event.stream.core.EventStreamService OSGI service.
Following is a sample code snippet.

Event event = new Event();
event.setTimeStamp(System.currentTimeMillis());
event.setStreamId("streamTest:1.0.0");
event.setPayloadData(new Object[]{data});
eventStreamService.publish(event);

Please note that Event Publisher Aggregate feature is not yet included
in carbon feature repo. It will be available with the immediate analytics
feature release.

[Dev] WSO2 Dockerfiles build logs

[Vishanth Balasubramaniam]

Hi,

Currently when building the wso2 docker images [1], we are not prompting
the complete image building logs [2], we are only prompting if there is any
error while building.

Is there any specific reason for not prompting the complete log trace when
building these images?

Isn't it better to show the complete build logs or at least an option for
user to see the complete logs? Thoughts?

Re: [Dev] Circuit breaker implementation for MSF4J

[Isuru Perera]

Hi Azeez,

We can use the "Meter" in metrics to record the number of failures per
second and use the rates in Meter (Mean, Last One Minute, Last Five Minutes
and Last Fifteen Minutes) for checking a certain threshold.

However we need following changes to be done in Carbon Metrics component.

   - Expose Meter Rates from the Carbon Metrics library. (Carbon Metrics
   didn't expose ways to read metrics from the Java APIs). For example,
   Dropwizard Meter [1] has APIs to read meter rates and Carbon Metrics Meter
   has only the basic APIs for using a Meter [2].
   - I will try to include these APIs in Carbon Metrics v2.0.0 release,
  which will be compatible with Carbon 5 products.
  - Initialize Metrics in a single place. Right now, MSF4J
   initialization code for Metrics is in msf4j-analytics component [3]. In
   MSF4J, the Metrics is initialized via the Metrics Interceptor [4]. When
   Circuit Breaker implementation also plans to use Metrics, we need to have a
   common way initializing metrics. (We need to think of a good design for
   that).

I will start working on these.

Thanks!

[Dev] Unable to send SOAP call.

[Shakila Sivagnanarajah]

Hi,

I am implementing an authenticator for WSO2-IS-5.1.0. I am
getting [1] exception while getting instance of
*javax.xml.soap.SOAPConnectionFactory* like [2]. But I imported the "
*org.apache.axis2.saaj.**" in pom. How can I fix this issue?

More Info: But did not get this error, if I use [3] to initiate the SOAP
connection. But getting [4] while building the SOAP message from response.
Since [5] is used to take instance of the SOAPMessage in
*org.apache.axis2.saaj.SOAPConnectionImpl* class.

[1] Unable to create SOAP connection factory: Provider
*org.apache.axis2.saaj.SOAPConnectionFactoryImpl* not found

[2] SOAPConnectionFactory soapConnectionFactory =
SOAPConnectionFactory.newInstance();

[3] SOAPConnection soapConnection = new
SOAPConnectionFactoryImpl().createConnection();

[4] Unable to create message factory for SOAP: Provider
*org.apache.axis2.saaj.MessageFactoryImpl* not found

[5]
MessageFactory mf = MessageFactory.newInstance();
SOAPMessage response = mf.createMessage();


Thank you

Hi Anurag,

Yes, the master branch is using java 8, hence you can use lambda

 Hi Anurag,

 Thank you for your interest in the above project. You can start by
 getting to know the Machine Learner product by downloading it and running
 it (Please use link [1] to download). Official documentation [2] will help
 you on using the product. You can find the source code base at [3] and [4].
 As we have mentioned in the project proposal as well, the main
 objective is to integrate ensemble support for the existing flow of the
 WSO2 Machine Learner. We are focusing on the three methods: Bagging,
 Boosting and Stacking.

 Please feel free to raise, if you have any questions or any unclear
 points.

Re: [Dev] Regarding the Location and Time-based Device Policy Enforcement Project for Gsoc2016

[Kasun Dananjaya Delgolla]

Hi Sameera,

Thank you for your interest in this project.


In order to get a better picture of the project make sure to build WSO2
EMM[1] including CDMF framework[2] using the git repositories listed.

Enroll a device and a publish a sample policy against the device and study
the current behavior of the policy.
You are expected to change the behavior a mentioned below.

Given policy must be activated automatically when the device enters a
predefined area.
Given policy must be deactivated when a device leaves a predefined area.
Given policy must be activated automatically in the given time frame.
Stats of the current policy, whether its active or inactive need to be
visible in the dashboard.
Policy compliance monitoring to the given device must be activated when a
policy is activated.

Project deliverable "Extension point for current EMM policy module with
location and time based policy publishing capability" includes followings,

   - Location based policy enforcement component.
   - A component which enables the location base policy monitoring and
  enforcement including statics.This need to be a extension to thee
  component which enabled device policies currently
   - Time based location component.
   - A component which enables the time base policy monitoring and
  enforcement including statics.This need to be a extension to thee
  component which enabled device policies currently
   - Location and time based policy configuration UI.
   - This is to enable users to configure and maintain the locations and
  time frames.The UI must have the ability to monitor the policies which
  is active in the device and compliance status.Above features must
  follow the current pattern used for policy monitoring and Policy
Management
  in WSO2 EMM.


While working with WSO2 EMM, if you found any bugs or improvements feel
free to let us know by using the oxygen tank[3].

Re: [Dev] Can we add a batch of resources to registry in one go?

[Isuruwan Herath]

It is done at the artifact level using the Zip Media Type handler. Yes, at
the core registry level it saves one by one. Currently there is no support
for bulk save at registry API level.

Well, the batch-upload option you've just described is something done
through the GovernanceArtifactManager impl? AFAIU, that too depends on the
core registry APIs at a low level right? So, I was just wondering if
there's any mechanism that allows us to do this at the core registry API
level. My primary intention is to update the whole batch in one-go without
doing multiple "registry.put()"s.

Re: [Dev] [DEV][DS] Render gadgets seamlessly (without IFRAME) in Dashboard server

[Manuranga Perera]

I think we have to keep the gadget concept as is, and bring in a new
concept. This was the initial plan with the widgets, but we removed it due
to above complications.
I think we can bring it back, and use WebComponent to implement it. But
unfortunately it’s not implanted in all browsers. But HTML template is [1].
Can you please do some research on this and find if we can leverage this to
implement the requirement.
Another option is to use WebComponent polyfills.

[Dev] [DEV][DS] Render gadgets seamlessly (without IFRAME) in Dashboard server

[Lasantha Samarakoon]

Hi all,

There is a recent requirement from ESB analytics dashboards, that they need
to wrap a jQuery data range picker within a gadget. In this case once the
date picker is expanded part of it get cropped down by the IFRAME borders.
In order to solve this issue, we thought of facilitating to render gadgets
without IFRAMES. But that approach may cause following issues.


   1. Shindig modifies the HTML content specified in the gadget's XML (add
   new scripts, css styles, re-order content and add extra HTML markup such as
   HTML, HEAD and BODY).
   2. Unable to provide DOM isolation to prevent script injections and
   style conflicts.
   3. Namespace conflicts may happen since multiple instances of a gadget
   may reside in a same page.
   4. Some of the Shindig features may not work as some of the parameters
   are previously sent via the IFRAME URL.


WRT these issues, it seems like the solution is not feasible for the
moment. Any other options or ideas to solve this issue?

Re: [Dev] Can we add a batch of resources to registry in one go?

[Isuruwan Herath]

For WSDL or WADL type resources you can use Governance Archive files for
batch upload. Otherwise, it is possible with a custom handler.

 This is great. Thanks a lot Malaka.
 Also, if we use the file connector as the outbound channel, will it
 work in the same way?
