Re: [Dev] [APIM] New Throttling Engine Database Schema Design

[Upekka Anuruddhi]

Whats are QUOTA_POLICY_TYPE, QUOTA attributes

Throttling can be done based on Request Count (Eg: 4000 req/5 min) or based
on Bandwidth (Eg: 100 MB/1 hour). QUOTA_POLICY_TYPE is either
"RequestCount" or "Bandwidth". QUOTA is the number of requests or the
bandwidth allowed.

why are these duplicated in AM_POLICY, AM_CONDITION tables?

Consider the scenario "Allow 20 req/min for requests coming from a
particular ip address range and allow 10 req/min for others". In the above
scenario the quota 20 req/min is relevant to condition (AM_CONDITION table)
and 10 req/min is the default quota relevant to Policy (AM_POLICY table).

 Hi Mohamed,

 We are glad to see your interest in this project. In order to make
 you familiar with this project with regard to WSO2 platform, we would 
 like
 you to complete the following task which would provide an 
 understanding on
 how the userstore managers are used in WSO2 products.


 1. Refer [1] and understand how a userstore manager can be written
 and used in a product like WSO2 Identity Server [2].

 2. Refer [3] and understand more about Claims and Claim Management.

 3. Referring [1], extend the
 *org.wso2.carbon.user.core.jdbc.JDBCUserStoreManager* class and
 write your own JDBC userstore manaager. (MySQL is preferred).

 4. Introduce a new claim called *lastPasswordResetTimestamp* which
 tracks the timestamp of each user's last successful password reset 
 attempt.
 (in WSO2 Identity Server). For this you can refer [1] and override the
 *doUpdateCredential*, *doUpdateCredentialByAdmin* methods in the
 custom userstore manager you wrote in previous step. Inside these 
 methods
 after successful password reset, set the current timestemp as a user 
 claim.
 For this you can refer [4].

 5. In the JDBC userstore manager you have written in above step,
 override the *doAuthenticate *method. Inside the method, after
 performing authentication, compare the timestamp of the last time the 
 user
 updated the credentials with current timestamp. If it is greater than 
 60
 days (you can hardcode this value for the moment) return an exception 
 with
 a message saying the user has to reset the password as it is expired. 
 (For
 the users where the claim for password reset timestamp is empty, you 
 can
 let the users successfully authenticate)

 Current connector [1] doesn't support on the $subject.  Github API [2]
 is supporting it, and need to implement the method inside the connector.
 As a workaround we can do traverse thorough the pull request (refer

[Vivekananthan Sivanayagam]

Hi Anuruddha,

I tried as you mentioned to check standalone mode and skipped squid proxy
test, but I got same error again. I followed this doc[1] to create ftp
connection.

[Dev] Fwd: SPI-Fly Mediator Service for Bundle Ordering

[Miraj Abeysekara]

-- Forwarded message --
From: David Bosschaert 
Date: Mon, Feb 15, 2016 at 3:04 PM
Subject: Re: SPI-Fly Mediator Service for Bundle Ordering
To: u...@aries.apache.org


Hi Miraj,

It's an interesting idea, however I'm not sure it will always work. The
problem is that you need to have your weaving hook registered before the
class to be woven is *loaded*, and I'm wondering whether this will provide
enough guarantees to know that the class is not yet loaded. I mean there
could be another bundle that loads the class that needs to be woven for
whatever reason and suddenly this approach will stop working...

The possibilities as they are right now are:
* Use start levels. Run the dynamic weaving bundle on a very low start
level (like 1) and run your other bundles on a higher start level (e.g. 2
or 4 or 50).
* Use static weaving [1]. This will do the weaving on a bundle at build
time and replace the to-be-woven classfiles with woven ones in the .jar.
This approach does not have any ordering constraints at runtime.
** You could even run the static weaving tool as part of your OSGi
framework provisioning phase, so statically weave bundles on-the-fly before
you are installing them.

I'm just wondering, is there any reason why one of these two approaches
doesn't work for you?

Cheers,

David

Re: [Dev] [DEV] [PET] Could not pass ftp over http proxy.

[Anuruddha Premalal]

Hi Vivekanathan,

Quick way to diagnose this is to add a main method and pass the parameters
and check whether it's working in standalone mode. That way you have more
power and control over debugging.

 As the error states it's trying to do a FTP upload via a close/unavailable
FTP connection so you can focus on the connection creation section and see
what's happening there, also at the same time monitor the FTP server logs,
I'd suggest to skip the squid proxy first and do the testing incrementally.

Regards,
Anuruddha.

[Dev] [DAS-3.0.1] Getting Table "METRIC_GAUGE" not found periodically

[Udara Rathnayake]

Hi,

Noticed following[1](DAS-3.0.1 with default H2 DB). As I noticed same
getting printed time to time even without any user interaction with DAS. Is
this something to do with the -Dsetup start after removing
wso2das-3.0.1/repository/database/*.

WSO2METRICS_DB.h2.db exists within the database directory, but I don't see
any tables inside, when I browse it using H2 console.

I have manually executed metrics h2 db script to get rid of this.
Any idea?

​yes.. If the payload is huge in size GET will not work.
Try to change the design. first do the POST and ​do what ever processing.
then do the redirect within a callback etc..

 pass the data to that page.  With response.sendRedirect i can redirect the
 page couldn't send the json. Is the a way i can do this ?

[Dev] [EMM][AppM] Emm is sending all of its devices in a specific tenant when user's devices are needed.

[Chathura Dilan]

Hi All,

In AppM EMM integration from OSGI[1] (line 163). I can see EMM retrieve all
of its devices and send it to AppM when user's devices are needed. This
should be filtered to get only users devices by AppM, not all devices which
is in the tenant.

Re: [Dev] Jaggery how to redirect the page with data(json)

[SajithAR Ariyarathna]

Hi Iqbal,

As RuwanA mentioned this is not a Jaggery or Java limitation. Simply you
cannot do this with HTTP. However there is a hack/workaround that you can
try.

You can stringify your JSON object and send it as a query param.

var payload = {name: "sajith", age: 10};
var url = "http://example.com?payload=; + encodeURIComponent(stringify
(payload));
response.sendRedirect(url);


*Disclaimer: Didn't tested.*


Nonetheless I must say that sending payloads in redirects is not a good
programming practice.
Thanks.

If I understand the question correctly, this can not be done. It will be in

Re: [Dev] Jaggery how to redirect the page with data(json)

[Nipuna Chandradasa]

Hi,

Did you try setting the content to the response as follow?

response.content = { products : ["Jaggery", "ESB"] };

I did not try this but this will possibly work.
Please refer the jaggery doc response section for more details.
Regards.

Re: [Dev] [APIM] New Throttling Engine Database Schema Design

[Lahiru Cooray]

Hi Upekka,
Please explain the below concerns:
Whats are QUOTA_POLICY_TYPE, QUOTA attributes and why are these duplicated
in AM_POLICY, AM_CONDITION tables?
(As per my understanding we are setting default values when defining a
policy and allow users to override when assigning to a condition. Is it the
scenario?)

Are policies applied against HTTP_VERBs? or against the Condition?

Better to give more meaningful names to attributes UNIT_TIME / TIME_UNIT
(AM_CONDITION)

Re: [Dev] GSOC 2016: Proposal 7

[Isuru Ranawaka]

Hi Dinanjana,

While you are reading the  documentation you can figure out important
features that needs to be included  and come up with a set of features.Then
we can finalize the scope of the project and start working on it. Since you
have already worked on  this kind of project can you propose set of
features and informations that will be helpfull to implement them.


thanks

 Hi all,
 As Nadeeshan has suggested earlier i built all 3 projects from the
 source. Many of the details of JVM Isuru suggested can be gained from
 java.lang.management. Other specific data i think can be gained from
 management package of carbon. I still have a very little understanding
 about the architecture of ESB. So what I can't understand is where to do
 the implementation?Are we talking about a "feature"  to ESB ?

[Dev] Installation issues of ESB fixed

[Awanthika Senarath]

The installation issues of ESB Tooling features are fixed,

the cache mediator issue and the data-mapper dependency issues were fixed
by aprropriately importing and exporting the versioned packages and
features from the relevant plugins.

The installation of the tooling main generated should be on top of a kernel
that has the patch0003 from [1] installed. Else there would be errors in
data-mapper dependencies.

Installation of tooling composite contains the fixed version of the
relevant feature.

I need to get the list of repositories that are accessible to the

Current connector [1] does not support for this but GitHub API [2] is
supporting it . So need to implement the method  inside the connector.

[Dev] Jaggery how to redirect the page with data(json)

[Irham Iqbal]

Hi All,

Is there any way to redirect the page + post the data(json) from a plain
jaggery file to another jaggery file. I tried with post and
response.sendRedirect. with post i couldn't redirect the page i only can
pass the data to that page.  With response.sendRedirect i can redirect the
page couldn't send the json. Is the a way i can do this ?

Thanks,
Iqbal

Re: [Dev] Carbon-Transport Disruptor ExecutorService threads

[Isuru Ranawaka]

Hi ,

I have added the support for configure worker pool in Disruptor and run
EventHandlers through it. you can configure
"disruptor.consumer.worker.pool.size" property as parameter in
netty-transports.yml  under TransportListener configurations.

thanks

 Hi,

 In carbon-transport, why are the number of event handlers and the
 number of threads in the ExecutorService of Disruptor [1] the same? Is
 there a way to configure them separately?

Re: [Dev] Regarding Proposal 6: [ML] Predictive analytics with online data for WSO2 Machine Learner

[Maheshakya Wijewardena]

Hi Heshani,

Please add WSO2 developers list as well when you are inquiring about
projects because the community is interested in these projects and their
input is vital and the decisions are made collaboratively.

That said, about your request; this projects is targeted to be a GSoC
project so the scope and the time line of the project should comply with
the GSoC official time lines. So there should be a concrete goal and
associated tasks that can be completed within that time frame. These tasks
should be properly discussed with the community and finalized, so that they
can go into the project proposal.
If you want to continue this as your final year project, you should discuss
about what more can be done (in addition to the components added in GSoC
project) and also find a supervisor. But this should be done independently
from the GSoC and you need to get approval from WSO2 for that.

As a starting point (considering GSoC), you can download Machine Learner
product, go through examples and quick start guide.
Then you can try developing small ML applications with Spark ML lib and
play around with Spark streaming as well.
After getting some concrete idea, try to write a program using Spark
Streaming and ML lib streaming linear regression, streaming k-means to
train models with streaming data and share your you experience with us.

Best regards.
