[Dev] [Siddhi] Partition with two attributes of same stream
Hi, During my recent testing, Siddhi does not allow partition with two attributes of the same stream. For example, the following query throws *SiddhiAppValidationException* with a message partition already exists because the streamId is used to uniquely identify the partition [1]. define stream PacketStream (srcIp string, dstIp string, packets int); partition with (srcIp of PacketStream, dstIp of PacketStream) begin from PacketStream select srcIp, dstIp, count(packets) as count insert into OutputStream; end; I wonder whether it is not supported due to any constraints. If there is nothing like that, I can have a look at it. FYI: I tried to change the partition id as a combination of stream id and the attribute name but it does not register a PartitionReceiver for the later one.

Re: [Dev] [Siddhi] non-matched or expired events in pattern query
Hi, If you can use Siddhi 4 snapshot release, it can be done using the new feature 'Absent Pattern' added to Siddhi 4. The query to detect the events that do not match the condition within 10 seconds is given below: from every e1=publisher -> not subscriber[e1.pid == pid] for 10 sec select e1.pid insert into not_completed_jobs_in_time; The above query waits for 10 seconds from the arrival of every publisher event and if there is no subscriber event with an id satisfying the condition arrived within that waiting period, the id of the publisher event will be inserted into the not_completed_jobs_in_time stream. I guess the official document for Siddhi 4 is under construction. So you can find more details about absent pattern at [1] Still, Siddhi 4 is not production ready so I wonder whether you can use this feature or not.

Re: [Dev] [Siddhi] TestUtility to throw Assertion Errors from main thread
Hi,
My last PR contains a check-style issue which causes to Sidhhi build
failure. Please merge my new PR #526
<https://github.com/wso2/siddhi/pull/526> which fixes the check-style issue
and also includes your suggestion.
Sorry for the check-style issue. I sent that PR just to make sure the
design so I didn't check the style.
Thanks & Regards,

[Dev] [Siddhi] TestUtility to throw Assertion Errors from main thread
Hi,
As per my experience during my GSoC project, the assertion errors thrown by
worker threads in the unit test callbacks do not interrupt the compiling
process.
I discussed with Suho during a code review and come up with a solution by
storing the assertion errors in a java.util.List and throw them later in
the main thread. I have sent a PR containing the prototype of my
implementation and a sample application of it [1]. Could you please check
the design, class name and the location.
I am thinking about adding overloaded methods with Predicates as shown
below but it can be used only in combined with Assert.assertTrue. WDYT?
public static TestCallBack addQueryCallback(SiddhiAppRuntime
siddhiAppRuntime, String queryName, Predicate... predicates) {
// ...
}

Re: [Dev] [GSoC][Siddhi][CEP]: Siddhi Pattern for Absence of Events
Hi, I defined the number of operands as the number of LogicalStreamProcessors that can be partners. Not is handled by one LogicalStreamProcessor so it can be partner with another LogicalStreamProcessor. Does it make sense?

Hi Suho, I have added the test cases to all the cases you have mentioned except the four listed below because having more than two pattern operands is not supported by Siddhi. I hope it is okay to skip those test cases. WDYT? - every ( (not C and D) and B ) -> A - every ((not C and D) or B ) -> A - every (B and (not C and D) ) -> A - every (B or (not C and D) ) -> A If there are no more cases to test, may I start with the SEQUENCE?

Re: [Dev] [GSoC][Siddhi][CEP]: Siddhi Pattern for Absence of Events
Hi,
The following absent event cases are implemented and tested so far and now
I am focusing on testing these patterns in the form of *Sequence*. If you
find any cases that I missed or any improvements, please share them.
A not B for 1sec
After the arrival of A, wait for 1 sec & B not arrived
A → not B and C
When C arrive if B is not available
A → (not B and C) within 1sec
If B not arrived but C arrived within 1 sec from A
A → (not B for 1sec and C) within 2sec
Wait for 1 sec from the arrival of A; if B not arrived and C arrived and
both happened within 2 sec from A
not A for 1sec → B
Wait for 1 sec; if A not arrived but B arrived after 1sec
not A and B → C
When B arrive if A is not available followed by C
every ( not B and A) → C
Every combination of the previous case
every ( not B for 1sec) → C
Check and emit C every second, if B not arrive
A → not B for 1 sec and not C for 1 sec
After A, both B and C are not received within 1 sec
not A for 1 sec and not B for 1 sec → C
A and B are not received for 1 sec and then C
A → not B for 1 sec or not C for 1 sec
After A, wait for 1 sec B or C not received
not A for 1 sec or not B for 1 sec → C
Wait for 1 sec; A or B not received followed by C
A → not B for 1 sec or C
After A, if C arrives, emit it otherwise emit after 1 sec if B not arrived
not A for 1 sec or B → C
Same as previous but the other way around
Thanks & Regards,
Gobinath

Re: [Dev] [GSoC][Siddhi][CEP]: Siddhi Pattern for Absence of Events
Hi,
I've fixed the duplicate output with 'OR' in the PR #354 [1]. According to
this fix, the *addState* method of *LogicalPreStateProcessor* treats both
PATTERN and SEQUENCE in the same way [2]. It does not break any existing
tests but please check whether it makes sense or not.

Re: [Dev] [GSoC][Siddhi][CEP]: Siddhi Pattern for Absence of Events
Hi,
I've found a minor bug and sent the PR [1] with the fix. Similar behavior
is noticed with *or* operator as well (Even after the fix). I have given
the code and the output below for your concern.
// Query: e1 or e2 -> e3
define stream Stream1 (symbol string, price float, volume int);
define stream Stream2 (symbol string, price float, volume int);
@info(name = 'query1')
from e1=Stream1[price > 20] or e2=Stream2[price >30] -> e3=Stream2['IBM' ==
symbol]
select e1.symbol as symbol1, e2.price as price2, e3.price as price3
insert into OutputStream;
// Input
Stream1.send(new Object[]{"WSO2", 55.6f, 100});
Stream2.send(new Object[]{"GOOG", 72.7f, 100});
Stream2.send(new Object[]{"IBM", 4.7f, 100});
// Output
Event{timestamp=1494203709496, data=[WSO2, null, 4.7], isExpired=false}
Event{timestamp=1494203709496, data=[WSO2, null, 4.7], isExpired=false}
If it is also a bug, please do let me know without merging the PR. I will
fix it under the same PR.

Re: [Dev] [GSoC][Siddhi][CEP]: Siddhi Pattern for Absence of Events
Hi,
Thanks for accepting my proposal. I have a question regarding the behavior
of *and* in a pattern.
// Query: e1 and e2 -> e3
define stream Stream1 (symbol string, price float, volume int);
define stream Stream2 (symbol string, price float, volume int);
@info(name = 'query1')
from e1=Stream1[price > 50.0f] and e2=Stream2['IBM' == symbol] ->
e3=Stream2[price > 20]
select e1.symbol as symbol1, e2.price as price2, e3.price as price3
insert into OutputStream;
// Input
Stream1.send(new Object[]{"GOOGLE", 72.7f, 100});
Stream2.send(new Object[]{"IBM", 4.7f, 100});
Stream2.send(new Object[]{"WSO2", 55.6f, 100});
// Output
Event{timestamp=1494169305631, data=[GOOGLE, 4.7, 55.6], isExpired=false}
Event{timestamp=1494169305631, data=[GOOGLE, 4.7, 55.6], isExpired=false}
Is this the expected output?. Note that the output contains two exactly
similar events but the pattern *e1 -> e2 and e3* outputs a single event [1].

Hi, A prototype is implemented and available at [1]. Currently the query support for absent patterns and two simple pattern identifications (e1 -> not e2 and not e1 -> e2) are implemented.

Re: [Dev] [Architecture] [IS] [Analytics] Improvement to use Siddhi streams to send notifications
Hi Suho and all,
The problem has been identified and fixed with the new commit [1].
According to this commit, the following changes have been done:
(1) No need to use arbitrary_ prefix anywhere.
(2) The publisher will first check for payload data, if not available it
will check for the arbitrary data. Therefore use the arbitrary data map
keys as they are. [2][3]
(3) Arbitrary data can be used in dynamic properties. [3]

Re: [Dev] Carbon UI Issue with JSI18N Mapping from JavaScript
Hi, I found the solution. I didn't add the jsi18n declaration in the parent JSP (In my case *create_event_publisher.jsp*) where the script was invoked. After adding it, everything works fine. Thanks.

Hi, When I use Carbon jsi18n mapping in JavaScript, it generates 'ReferenceError: org_wso2_carbon_event_publisher_ui_jsi18n is not defined' error in the browser.
