I guess this happen due to the database connection mentioned in the dbs. It
requires to restart the server.

Re: [Dev] Correct formats of x-www-form-urlencoded

2018-01-03 Thread Vijitha Ekanayake

Hi Senduran,

AFAIK, There is no standard documentation on how to convert JSON to
x-www-form-urlencoded format as key-value pairs. As mentioned by Thusitha,
When the JSON is getting complicated converting it to the
x-www-form-urlencoded will also become complicated and may lead to
inconsistencies over different payloads. Therefore I too think, we should
use multipart/form-data in such situations.


Thanks.

Re: [Dev] [IS] How to check whether an OAuth application is already revoked or not

Hi Maneesha,

You can use 'OAuthAdminService' to check the state of the oauth app.
There's 'getOauthApplicationState' operation which returns the application
state for a given consumer key.

I'm configuring playground as a Service Provider while trying Solution 01

I'm just curious on how to determine whether an oauth application is

the 'revoke' button and it will give a popup of 'Application is already

Re: [Dev] [EI-DSS] Check backend latency when use local transport

2018-01-03 Thread Madhawa Gunasekara

Hi Godwin,

We can use log4jdbc to check the backend latency of DB Calls. [1]

What you have to do is

1) download the log4jdbc jar and paste into the lib folder.
2) modify the log4j.properties file with your preferences :

log4j.logger.jdbc.sqltiming=INFO

3) change the integrator.sh file to pass the system properties, you have to
specify the driver class in that property
*-Dlog4jdbc.drivers=[,...] *
4) change the datasource configurations as mentioned in the documentation.

   - JDBC Driver from* com.mysql.jdbc.Driver *to
   *net.sf.log4jdbc.DriverSpy *
   - MySQL JDBC Connection string changed from
   *jdbc:mysql://localhost:3306/test* to
   *jdbc:log4jdbc:mysql://localhost:3306/test*

AFAIR deployment flows are different for ESB artifacts and DSS artifacts,
DSS artifacts are getting deployed via axis2 deployer(that is it will pick
up changes from file system and get deployed, so with car files, this won't
happen as the actual file does not get changed) whereas when we change ESB
artifacts, it will directly invoke the deployment flow. This was the
behavior we had and since it is not recommended to update artifacts within
a car file, we haven't done any changes to DSS behavior, hence the
difference.

Thanks,

Re: [Dev] [EI] Data services are not hot deploying

2018-01-03 Thread Godwin Shrimal

Hi Vinod,

If you change anything in Proxy (deployed using CAR) it's getting hot
deploy. Yeah, changes get discard once server restart. Again my problem is
why proxy services changes reflect and not in DSS.


Thanks

Re: [Dev] [EI] Data services are not hot deploying

2018-01-03 Thread Vinod Kavinda

Hi Godwin,
Proxy deployers and DSS deployers are different components. Maybe we are
not listening to the unpacked carbon apps folder by the DSS deployer. Yes,
this is useful for testing. Let's report a bug. We can fix if it is
technically feasible.

Yes, It's a bug. Normally If we do a change in CApp, It will reflect the
service. but In this case, It's not working as expected.

I have noticed the same. This happens in the data services server 3.5.1

Is this a bug?

Re: [Dev] [VOTE] Release WSO2 Stream Processor 4.0.0 RC2

2018-01-03 Thread Chandana Napagoda

Hi Raveen,

In Carbon 4.4.x code I could see that, 'sh' command[1] is used to determine
whether the operating system is Windows or not. So based on the code you
have pointed[2],it has changed to 'bash' and now the new 'bash' option is
not working on some of the Windows systems.  I could confirm that old
carbon 4.4.x related 'sh' command still works without any issue and I
haven't noticed anyone faced a similar issue(in Dev list or StackOverflow)
with any of the official WSO2 products up to now.

So I personally believe that, the code you have pointed[2] it is not
working as expected(on the expected use cases)[3] and need to be fixed it
properly.

Re: [Dev] [EI] Data services are not hot deploying

2018-01-03 Thread Godwin Shrimal

Hi Pubudu,

Yeah, I know it's not recommending, But when we are doing testing, think
you want to add a small log to the proxy, you simply can add it via UI and
test it.

My Question is not about the recommendation, it's about why DSS behaving
differently than the proxy services.

Thanks

Hi Godwin,

AFAIK, we should not change any artifact which is deployed using a CAR
file. This is not recommended. I am not sure about the reasons for this
behavior.

Re: [Dev] [Architecture] APIM Statistics introduce new field to the Analytics events

2018-01-03 Thread Hasitha Hiranya

Hi,

One scenario I faced with a customer is as follows.

1. A Custom HTTP header is coming with each request specifying the region
request was originated.
2. At gateway, this needs to be extracted as an field and published to
Analyser.
3. Analyser summarises the data and put to a DB (hourly/daily/monthly stats)
4. A dashboard can pull that data and show.

As per current implementation, we need to

1. Write a custom handler to extract values
2. Create a new stream to publish new field
3. Learn apache spark queries to perform summarisation
4. Learn Jaggery and create the dashboard

Are we discussing a customisable way to provide above functionality here?
If so, yes, it will be a great value addition.

Thanks

 Hi All,

 Can we check the possibility of the $Subject. In the latest
 APIM(wso2am-2.1.0-update4), correlation ID and the key type(sand or prod)
 is include in the event as JSON attribute[1]. I think it is better to moved
 those attributes as a single value attribute and passed to the Analyzer.
 So we can upgrade the stream versioning and do these changes.

 Also it is better to persist key type, data center ID in the STAT_DB
 and we can filter production and Sandbox analytics future. So when
 migrating we need to alter tables with key type. But we can assume that
 existing data are from the production key and insert those key type when
 migrating.

 So Any idea about this?

 "19c4350a-2079-406a-bece-808954b4f2d7"}

Re: [Dev] Difference between SESSION_TRANSACTED Ack Mode and transport.jms.SessionTransacted property

2018-01-03 Thread Hasitha Hiranya

Hi Asanka/Heshitha,

Yes. If we create a transacted session all ACK modes are invalidated.
Only commit() and rollback() is possible in a transacted session.
Hence one flag is enough to denote if it is transactional.

Thanks

Re: [Dev] [VOTE] Release WSO2 Stream Processor 4.0.0 RC2

2018-01-03 Thread Raveen Rathnayake

Hi Chandana,

I was able to reproduce your issue. This issue is caused due to an
uncompleted bash installation in Windows 10.
With windows 10 (10th year anniversary edition) users were given the option
to install bash within windows. So once you have installed *Windows sub
system for Linux(beta)* feature it actually doesn't completely install all
of its features. This creates a '*bash.exe*' in system32 folder and it will
be installed when the "bash" command runs.

In carbon-kernel [1] we try to write a PPID using a bash command. In
windows environment we expect an exception when trying to execute this step
since bash is not available in windows. But in this case bash is available
in the windows environment and an exception is not generated. So the
process continues and it try to read a line in [2] but it hangs there
because once we execute the "*bash*" command it tries to install bash in
windows(user input is required to install it)

So, to resolve this issue we can install bash completely by running "*bash*"
command in command prompt or remove the *Windows sub system for
Linux(beta) *feature.

I hope this is the same reason for your issue as well. (you can check
whether you have partially installed bash by typing "bash" in command
prompt. This will ask you to install it properly.)

Let us know if this helped you to resolve the issue.

PS: Complete tutorial on installing bash in windows 10 is available in [3].

Re: [Dev] Outbound provisioning for roles which have permission

Hi Nila,

AFAIR it uses SCIM to do outbound provining. SCIM protocol doesn't have a
standard way to provision permissions. I think thats the reason for this.

2018-01-03 Thread Heshitha Hettihewa

Hi,

Thanks for the clarification. Since transacted sessions invalidates other
ack modes and omitting the transport.jms.SessionTransacted parameter will
omit ambiguous parameter definitions, +1 for using SESSION_TRANSACTED as
Ack mode only. But since omitting it will cause backward compatibility
issues shall we set isTransacted flag to true on ack mode as chanika
suggested and generate a deprecated message for
transport.jms.SessionTransacted parameter. WDYT?.

[Dev] Correct formats of x-www-form-urlencoded

2018-01-03 Thread Senduran Balasubramaniyam

Hi all,

When an XML or a JSON is converted to  x-www-form-urlencoded format the key
value pair is created.
i.e


  value1
  value2


will be converted to key1=value=value2

similarly

{"key1" : "value1", "key2" : "value2"} also get converted to
key1=value=value2

But what if the XML or JSON is not only having simple key value i.e having
an array or a child element

for example,

  value1
  
subvalue1
subvalue2
  


similarly for JSON like
{"key1" : "value1", "key2" : {"subkey1" : "subvalue1"}} or

JSON with array
{"key1" : "value1", "key2" : ["arrayvalue1", "arrayvalue2"]}


Kindly let me know the available correct formats for
application/x-www-form-urlencoded content type.
Further it will be really helpful if you could point to a specification or
a standard document

Thanks
Senduran

Re: [Dev] [VOTE] Release WSO2 Stream Processor 4.0.0 RC2

2018-01-03 Thread Raveen Rathnayake

Hi Chandana,

I was able to reproduce your issue. This issue is caused due to an
uncompleted bash installation in Windows 10.
With windows 10 (10th year anniversary edition) users were given the option
to install bash within windows. So once you have installed *Windows sub
system for Linux(beta)* feature it actually doesn't completely install all
of its features. This creates a '*bash.exe*' in system32 folder and it will
be installed when the "bash" command runs.

In carbon-kernel [1] we try to write a PPID using a bash command. In
windows environment we expect an exception when trying to execute this step
since bash is not available in windows. But in this case bash is available
in the windows environment and an exception is not generated. So the
process continues and it try to read a line in [2] but it hangs there
because once we execute the "*bash*" command it tries to install bash in
windows(user input is required to install it)

So, to resolve this issue we can install bash completely by running "*bash*"
command in command prompt or remove the *Windows sub system for
Linux(beta) *feature.

I hope this is the same reason for your issue as well. (you can check
whether you have partially installed bash by typing "bash" in command
prompt. This will ask you to install it properly.)

Let us know if this helped you to resolve the issue.

Re: [Dev] Difference between SESSION_TRANSACTED Ack Mode and transport.jms.SessionTransacted property

2018-01-03 Thread Chanika Geeganage

According to the spec, if session transacted, the session should be
committed/ rollback. But in our code we set isTransacted flag to true only
if transport.jms.SessionTransacted is set, but not when the acknowledge
mode is set to SESSION_TRANSACTED, and therefore session commit/rollback
happens only when transport.jms.SessionTransacted is set [1]. Do we have to
change that logic to commit/rollback when the acknowledge mode is set to
SESSION_TRANSACTED also?

Re: [Dev] Difference between SESSION_TRANSACTED Ack Mode and transport.jms.SessionTransacted property

2018-01-03 Thread Asanka Abeyweera

Hi Heshitha,

There are two methods we can use to create a transacted session in JMS,

   1. createSession(boolean transacted, int acknowledgeMode)- you can set
   the transacted parameter to true to create a transacted session.
   Acknowledge mode is ignored when the transacted parameter is set to true.
   2. createSession(int sessionMode) - you can use SESSION_TRANSACTED as
   acknowledge mode to create a transacted session. AFAIK this method is
   only vailable in JMS 2.

You can use either of the methods depending on the JMS version used and the
behaviuor should be similar.

Re: [Dev] Difference between SESSION_TRANSACTED Ack Mode and transport.jms.SessionTransacted property

2018-01-03 Thread Asanka Abeyweera

I think that pattern corresponds to how the 1st method (createSession(boolean
transacted) type works. That is we ignore the acknowledge mode and use the
transport.jms.SessionTransacted parameter for creating transacted sessions.
Maybe to improve the user experience we can omit the
transport.jms.SessionTransacted
parameter and use the acknowledge mode for all modes including transacted
sessions. WDYT?
