Re: [Dev] An option to drop all categorical variables

[Supun Sethunga]

+1,

Think we should have an option to deselect-all/select-all features as well.
(why? : if there are hundreds of features and if the user wants only a few
features to their model, then he should be able to "deselect all" and
select only the necessary ones).

 In addition to that I think we need a 'search' for features too.

we have :)

[Dev] Puppet modules - Cleaned up jdk and product distribution

[Sajith Kariyawasam]

Hi Devs,

With the current puppet modules, when docker images are built it sized
around 2.216 GB and it seemed product and JDK binaries were not removed
after the installation.

I have now updated the puppet modules to,

1) Remove java cache directory after java installation
2) Remove wso2 product pack after installation

Ideally, JDK distribution should be cleaned up by the 7-terminals [1]
module. I have sent a PR [2] with the improvement, until its merged and
available in puppet forge I have fixed that in java.pp

Now the image size is reduced to around 1.417 GB

[1] https://github.com/7terminals/puppet-java.git
[2] https://github.com/7terminals/puppet-java/pull/14

Thanks,
Sajith

Re: [Dev] [VOTE] Release WSO2 Microservices Server 1.0.0 RC4

Hi Devs,

I have worked with Dhakshika on the issue and we found out the reason for
the issue, when access the petstore UI, backend servers not properly up and
running. (in the background servers still booting up). But if we wait few
seconds and tried the app, it working as expected.

since this in not a code issue, I'm withdraw my -1  and giving +1

Re: [Dev] SCIM PUT/PATCH group with members in order to add a new member

[Chamila Wijayarathna]

Hi Xavaier,

I could run the steps you have mentioned above without any issue in my IS
5.1.0 setup.

In your case it seems like the issue is in your step 3 (Create second
user). There you have intended to create a user, but has sent  a GROUP POST
request to SCIM group endpoint, so there it will create a group not a user.
So there is no user with id '1b97b894-5cbe-4b39-b6ce-9606debc5a28'. This is
why your requests are failing. Please check that, it will fix your issue.

Thank You!

Exactly! It's better to have more generic ones as much as possible instead
of specific options. Anyway drop all categorical features seems fair enough
option. For select all/none we have something here [1]. Please talk to UX
guys if we're gonna add them. Not sure whether this supports DataTables.

[Dev] Why are we passing Algorithms Name to update Hyper-parameters?

[Supun Sethunga]

HI,

Any idea for $subject, at [1] ? Isn't the analysis id is sufficient? or was
there any reason to do so?

Issue is, if the user passes a wrong/mismatching algorithm name (than the
actual algo name in the analysis) here, it updates the "ML_HYPER_PARAMETER"
table with this algo name, while keeping the "ML_MODEL_CONFIGURATION"
table's algo name unchanged. This leads to data inconsistencies in
retrieving data via REST API.

Think we don't need to store alog name in ML_HYPER_PARAMETER table in the
first place. But if we need to do so for some reason, then best approach is
to get it from the ML_MODEL_CONFIGURATION table and update the
ML_HYPER_PARAMETER table.

Re: [Dev] [ESB] What is usage of OAuth Mediator

[Vijitha Ekanayake]

Hi Abimaran,

AFAIK, OAuth mediator or OAuth Handler is used in similar
purposes(authenticate clients to secured services). One difference could be
the request intercepting points are different in a mediator and a handler.
Oauth mediator can be used authenticate to proxy service and normal Oauth
API handler only used authenticate requests comes to API which cannot use
to authenticate proxy services.

Following blog posts may be helpful to you:

Re: [Dev] Latency Calculation Feature in WSO2 GW

[Chamil Elladeniya]

Hi all,

Currently I'm tasked with implementing latency metrics calculation feature
according to the proposed architecture [1]. So far I have integrated
carbon-metrics and working on load testing to check if there is any
performance degradation of GW.

[Dev] Request the PRs to be merged (analytics-common & event-processing repos)

[Ruwan Yatawara]

Hi Team,

Ran in to a few OSGI issues again whilst packing DAS components in IoTS and
did some fixes. Can we get the below PRs ([1] & [2]) merged to the
respective Repos and get them released?

There is another fix that need to go in to carbon-analytics. But in order
to add that fix, the following two repos need to be released as they are
inter-dependent.

[1] - https://github.com/wso2/carbon-event-processing/pull/197
[2] - https://github.com/wso2/carbon-analytics-common/pull/174

Thanks and Regards,

[Dev] Generating OAuth token without using WSO2 API Manager?

[Anvaari Mohsen]

Hi,

I am trying to invoke registry Rest API of WSO GREG. A part of the request is 
of course the auth and I need to generate an OAuth access token. In GREG 
documentation it is 
written
 that I should use API manager to generate the access token. Is there any way 
to generate token without using API manager? I want to use only GREG in my 
integration platform. Is there any solution to do it without installing API mgr?

[Dev] SCIM PUT/PATCH group with members in order to add a new member

[Xavier Pegenaute M2M]

Hi again,

first, thanks a lot for your previous answers. This time I had some 
problem updating a group when it has already some member. My steps are 
shown below:


*1) Create a first user*
curl -k --user admin:admin --data 
"{"schemas":[],"name":{"familyName":"John","givenName":"Doe"},"userName":'groupUSR001',"password":"testPwd123"}" 
--header "Content-Type:application/json" 
https://localhost:9443/wso2/scim/Users


{"id":"9b0585d0-646e-4eee-9d8a-342203540510","schemas":["urn:scim:schemas:core:1.0"],"name":{"familyName":"John","givenName":"Doe"},"userName":"groupUSR001","meta": 
{"lastModified":"2016-01-25T08:50:55","location":"https://localhost:9443/wso2/scim/Users/9b0585d0-646e-4eee-9d8a-342203540510","created":"2016-01-25T08:50:55"}}


*2) Create a group with a member*
curl -k --user admin:admin --data "{"displayName": 'ngioletGR', 
"members": [{"value": "9b0585d0-646e-4eee-9d8a-342203540510", "display": 
"groupUSR001"}]}" --header "Content-Type:application/json" 
https://localhost:9443/wso2/scim/Groups

*3) Create a second user*
curl -k --user admin:admin --data "{"displayName": 'ngioletGR2', 
"members": [{"value": "9b0585d0-646e-4eee-9d8a-342203540510", "display":

*3a) PATCH group to add the last user*
curl -k -X PATCH --user admin:admin --data "{"displayName": 'ngioletGR', 
"members": [{"value": "9b0585d0-646e-4eee-9d8a-342203540510", "display":

_{"Errors":[{"description":"User: 1b97b894-5cbe-4b39-b6ce-9606debc5a28 
doesn't exist in the user store. Hence, can not update the group:

*3b) PUT group **to add the last user*
curl -k -X PUT --user admin:admin --data "{"displayName": 'ngioletGR',

Am I wrong in some step?, I am using IS 5.1

[Charitha Goonetilleke]

Hi all,

When we are doing developments with IoTServer, we realized that, IoTServer
takes some time to start from wso2server.sh script. Usually it takes nearly
120 seconds. I think it is much more higher than our other products. By the
way when analyzing the server logs, I found that, there is a time gap
between 1st INFO level log and last output from the startup shell script.
It is nearly around 1 minute.

WDYT about this? Is there any work around to fix this issue?

Re: [Dev] Issue activating osgi component with the service component reference

[Danushka Fernando]

Have you checked debugging? Is it hitting the activate method. And the
activated service component, does it same as your scr reference name?

Can you attach the service component code? May be its not hitting the
service component class.

 Hi all,

 I am writing an osgi component. This same component wants to be
 deployed in both Appfactory and APIManager servers. Here, I have
 imported some of the appfactory packages such as
 org.wso2.carbon.appfactory.application.mgt.* which will not be
 resolved in APIM 1.9.1.
 Then I used ;resolution:=optional in the pom file for those packages
 and I set service component reference cardinality to "0..1"

 @scr.reference name="application.applicationInfoService"

 interface="org.wso2.carbon.appfactory.application.mgt.service.ApplicationInfoService"
 cardinality="0..1"
 policy="dynamic" bind="setApplicationInfoService"
 unbind="unsetApplicationInfoService"

 When I start the server(APIM 1.9.1) the log that gets printed when the
 component gets activated is not printed implying it has not been
 activated, but osgi console says that the bundle has activated.

 What would be the problem? Any suggestions would be appreciated.

[Dev] [DAS] Spark clustering and DAS analytics cluster tuning

[Niranda Perera]

Hi,

I added 2 blog posts explaining how Spark clustering works [1] and how to
manage the resources in a DAS analytics cluster [2].

@Rukshani, some of the content should go to this doc [3]. Can we work on
that?

Re: [Dev] US Election 2016 Tweet Analyze System

[Thusitha Kalugamage]

Hi Yudhanjaya,

1) Yes we could, but since the Image is appended dynamically I used the
same property to create its background,
If we are to use a color, we would have to parse a color property as well.
@Dinali shall we do that?

2) Yes, Already added three tabs to ticker and moved "News" as one of three
tabs in the second row [1]

 Hi Kishanthan,

 The redeploy all of a small system its ok, but for a big one, its a
 problem, just a change in one class you must redeploy, loose sessions,
 restart the system from scratch, to reach the point of test again, with the
 ideas used by HotSwapAgent they act on reloading only that one class
 changed, this way speeds the development time, these ideas are well
 defended by JRebel tool, that HotSwapAgent tends to be a choice as an open
 source solution. Please note that this feature is only needed for
 development phase, in production, the scheduled task its ok.

 I mean time I tested with AS 5.3.0, JRebel and HotSwapAgent, JRebel
 trial worked as expected, but HotSwapAgent not (see exception bellow [1]),
 I will check these problems with HotSwapAgent devs, and try to discover why
 dont works with WSO2 AS as with HotSwapAgent active none of webapps load,
 all get that exception, as we see a NPE in class CarbonWebappClassLoader
 maybe its the way they initialize the dependent class loaders.

[Dev] Issue activating osgi component with the service component reference

[Nipuna Prashan]

Hi all,

I am writing an osgi component. This same component wants to be
deployed in both Appfactory and APIManager servers. Here, I have
imported some of the appfactory packages such as
org.wso2.carbon.appfactory.application.mgt.* which will not be
resolved in APIM 1.9.1.
Then I used ;resolution:=optional in the pom file for those packages
and I set service component reference cardinality to "0..1"

@scr.reference name="application.applicationInfoService"
interface="org.wso2.carbon.appfactory.application.mgt.service.ApplicationInfoService"
cardinality="0..1"
policy="dynamic" bind="setApplicationInfoService"
unbind="unsetApplicationInfoService"

When I start the server(APIM 1.9.1) the log that gets printed when the
component gets activated is not printed implying it has not been
activated, but osgi console says that the bundle has activated.

What would be the problem? Any suggestions would be appreciated.

Re: [Dev] Handling time-consuming processes within Carbon Metrics Gauges

[Isuru Perera]

Yes. It's better to profile and see.

I also discussed with Grainier and we think it's better to use "DEBUG" or
"TRACE" level when creating the gauge for memory consumption.

In that way, we can enable these kinds of gauges in runtime only when we
need. (The Carbon Metrics has a feature to support changing the configured
level dynamically at runtime via a JMX operation)

Thanks!

 Hi Granier, Suho

 The memory calculation will be a time consuming issue since it has to
 traverse through the complete object tree. IMO, we should have the option
 of executing matrix calculation in a separate thread and report back to the
 caller with the result.

 I think it's a valid case to have matrices which consume time/resources
 to calculate. Therefore, it will be a good idea to make available the
 option of matrix calculation to be asynchronous and report back once done
 in carbon metrics library it self.

 WDYT?

Update,

   1. Added assigned colors for candidate backgrounds as suggested.
   2. With Yasara's input on News tab, moved next to the Sentiment Analysis
   Graph.

Can you check whether your service component is activated? You can type the
"ls" command.

 Instead of doing this, do -DdisableMLSparkCtx=true this would disable
 ML Spark Context creation but predictions should still work.

[Dev] Evaluating the possibility of applying Goldmansachs ConcurrentHashMap in MB

[Malaka Gangananda]

Hi,

While profiling the MB we found out that there is a performance bottle neck
in using util.ConcurrentSkipListMap. Because every time size call is made
it has to loop through the data structure so it takes O(n) time. But
looking at GC ConcurrentHashMap we found out that it only takes constant
time (O(1) time) to make the size call.Other operations on GC
ConcurrentHashMap are also faster than uti.ConcurrentSkipListMap.

Here I have attached JMH Benchmark results which acquired by testing
util.ConcurrentSkipListMap vs GC ConcurrentHashMap
