jBPM 6.2.0 Send Velocity Template Email Notification on Task Creation - velocity

Hi I am working on jBPM 6.2.0.
I need to send a Velocity Template Email Notification, upon Human Task creation. Do I need to write a separate Email Notiification Handler ? And how do I make sure it gets called in task Creation.
Please Note: Performance is an issue for us, we need to complete execution of each task in less than 1 sec.
Tech Stack:
jBPM 6.2.0.Final
Oracle 11g
Java 1.7
Any help is appreciated.

Sonar Api: After scan is finished on new pull request it’s not possible to get /api/measures/component?metricKeys=coverage

SonarQube: Enterprise Edition Version 9.2.4 (build 50792)
Sonar client: 4.7.0.2747
Scan is launched for merge request in gitlab. I am requesting coverage for pull request.
Imidietly after scan (using scanner client) is finished I try to get coverage by following call:
http:///api/measures/component?metricKeys=coverage&component=&pullRequest=
I am getting:
404 : “{“errors”:[{“msg”:“Component \u0027u0027 of pull request \u0027\u0027 not found”}]}”
Interestingly if I put some sleep (1 second) after scan is finished and before i do a call to get coverage everything is fine.
It seems it has to do something with the fact that it’s a new pull request and regardless scan is finished and it generates link with results, it still requires some time before it will be possible for the api call i mentioned to be able to return coverage. Also, if i retry the operation(scan and get results) on already existing pull request there are no issues like this.
Could you please elaborate on this issue, is such behavior is expected or maybe there are some other ways I can get coverage right away after the scan is finished without adding any sleeps…
As a side observation under same circumstances if i do scan on new pull request and call another api (/issues/search?) to get list of detected issues and it successfully works without any additional sleeps,
Thank you.
After the call from the scanner client completes, SonarQube executes a "background task" in the project that finalizes the computations of measures. When the background task is complete, your measures will be available. This is why adding a "sleep" appears to work for you. In reality, it's just luck that you're sleeping long enough. The proper way to do this is to either manually check the status of the background task, or use tools that check for the background task completion under the covers.
If you're using Jenkins pipelines, and you have the "webhook" properly configured in SonarQube to notify completion of the background task, then the "waitForQualityGate" pipeline step does this, first checking to see if the task is already complete, and if not, going into a polling loop waiting for it to complete.
The machinery uses the "report-task.txt" file that should be written by the scanner. This is in the form of a Java properties file, but there's only one property in the file that you care about, which is the "ceTaskId" property. That is the id of the background task. You can then make an api call to "/api/ce/task?id=", which returns a block that tells you whether the background task is complete or not.

Not able to approve tasks in Documentum D2

In one of the workflows, task notification has been sent to an user's inbox. When the user tries to acquire the task, he is getting the error like missing package for the current task of the workflow.
Kindly provide me the suggestion on resolving this issue.
During the Workflow definition if the Package is added as Mandatory Package, and during task completion process if the task attachment is missing, user is expected to get this message in D2 client.
Please check weather the Task attachment is missing from repository in this scenario.
You can either:
Verify if the associated activity definition for the task (from process builder for example) has defined correctly the package/s.
or
Verify if the attached object (document/s or folder/s) to the task exists in repository or the user has at least BROWSE permission on it.
Also, a good idea is to check the D2 app server and JMS logs.

Can you have automated regression/integration tests for Azure Logic Apps?

Can you have automated regression/integration tests for Azure Logic Apps?
And if you can, how? ... especially in the context of CI/CD builds and deployments
... and if you can't, why not!!
There isn't any out-of-the-box tooling yet to provide automated testing of Azure Logic Apps. We have a few customers who have followed one of the following patterns. There is also this article that goes into detail on how to create a Logic App deployment template:
After deployment (using a release management tool like Visual Studio Release Management), a series of unit tests are run (writtin in something like C#) to test the Logic App.
Since a logic app could have any kind of trigger (on queue item, on HTTP request), the code usually performs the action and asserts the result.
A logic app in the resource group that can run a series of basic tests in a workflow. This one requires a bit more chewing on, but idea being you have a workflow that makes use of connectors or "calling nested apps" to perform basic validation tests (ensure connections are active, etc.)
It's something we have had discussions on from time-to-time, but would love to know if you have any thoughts on what types of tooling/configuration you'd want to configure for an app (remember that some apps "trigger" on something like a message in a queue or a file in FTP).
I would like to share one of the approach for LogicApp testing that my team has followed.
First level of validation is the ARM template deployment status (ProvisioningState) which should not have any errors.
After that we have developed test automation using the logic app sdk which does the following
Get auth token.
Execute a specific logic app trigger with a synthetic transaction.
Waits till the execution is completed.
Gets logic app & its action status (succeed, failed or skipped), validates it as per the expected scenario.
Gets the outputs from each action execution, validates them against an expected scenario.
Repeat above steps for all the various cases that logic app might go through.
Hook this all-in CI/CD :)
Deployed an LA, ran a synthetic transaction & validated the results.
Hope this helps.

Best way to run scheduled tasks in ASP.NET CORE [duplicate]

Today we have built a console application for running the scheduled tasks for our ASP.NET website. But I think this approach is a bit error prone and difficult to maintain. How do you execute your scheduled task (in an windows/IIS/ASP.NET environment)
Update:
Examples of tasks:
Sending email from an email-queue in the database
Removing outdated objects from the database
Retrieving stats from Google AdWords and fill a table in the database.
This technique by Jeff Atwood for Stackoverflow is the simplest method I've come across. It relies on the "cache item removed" callback mechanism build into ASP.NET's cache system
Update: Stackoverflow has outgrown this method. It only works while the website is running but it's a very simple technique that is useful for many people.
Also check out Quartz.NET
All of my tasks (which need to be scheduled) for a website are kept within the website and called from a special page. I then wrote a simple Windows service which calls this page every so often. Once the page runs it returns a value. If I know there is more work to be done, I run the page again, right away, otherwise I run it in a little while. This has worked really well for me and keeps all my task logic with the web code. Before writing the simple Windows service, I used Windows scheduler to call the page every x minutes.
Another convenient way to run this is to use a monitoring service like Pingdom. Point their http check to the page which runs your service code. Have the page return results which then can be used to trigger Pingdom to send alert messages when something isn't right.
Create a custom Windows Service.
I had some mission-critical tasks set up as scheduled console apps and found them difficult to maintain. I created a Windows Service with a 'heartbeat' that would check a schedule in my DB every couple of minutes. It's worked out really well.
Having said that, I still use scheduled console apps for most of my non-critical maintenance tasks. If it ain't broke, don't fix it.
I've found this to be easy for all involved:
Create a webservice method such as DoSuchAndSuchProcess
Create a console app that calls this webmethod.
Schedule the console app in the task scheduler.
Using this methodology all of the business logic is contained in your web app, but you have the reliability of the windows task manager, or any other commercial task manager to kick it off and record any return information such as an execution report. Using a web service instead of posting to a page has a bit of an advantage because it's easier to get return data from a webservice.
Why reinvent the wheel, use the Threading and the Timer class.
protected void Application_Start()
{
Thread thread = new Thread(new ThreadStart(ThreadFunc));
thread.IsBackground = true;
thread.Name = "ThreadFunc";
thread.Start();
}
protected void ThreadFunc()
{
System.Timers.Timer t = new System.Timers.Timer();
t.Elapsed += new System.Timers.ElapsedEventHandler(TimerWorker);
t.Interval = 10000;
t.Enabled = true;
t.AutoReset = true;
t.Start();
}
protected void TimerWorker(object sender, System.Timers.ElapsedEventArgs e)
{
//work args
}
Use Windows Scheduler to run a web page.
To prevent malicous user or search engine spiders to run it, when you setup the scheduled task, simply call the web page with a querystring, ie : mypage.aspx?from=scheduledtask
Then in the page load, simply use a condition :
if (Request.Querystring["from"] == "scheduledtask")
{
//executetask
}
This way no search engine spider or malicious user will be able to execute your scheduled task.
This library works like a charm
http://www.codeproject.com/KB/cs/tsnewlib.aspx
It allows you to manage Windows scheduled tasks directly through your .NET code.
Additionally, if your application uses SQL SERVER you can use the SQL Agent to schedule your tasks. This is where we commonly put re-occurring code that is data driven (email reminders, scheduled maintenance, purges, etc...). A great feature that is built in with the SQL Agent is failure notification options, which can alert you if a critical task fails.
I'm not sure what kind of scheduled tasks you mean. If you mean stuff like "every hour, refresh foo.xml" type tasks, then use the Windows Scheduled Tasks system. (The "at" command, or via the controller.) Have it either run a console app or request a special page that kicks off the process.
Edit: I should add, this is an OK way to get your IIS app running at scheduled points too. So suppose you want to check your DB every 30 minutes and email reminders to users about some data, you can use scheduled tasks to request this page and hence get IIS processing things.
If your needs are more complex, you might consider creating a Windows Service and having it run a loop to do whatever processing you need. This also has the benefit of separating out the code for scaling or management purposes. On the downside, you need to deal with Windows services.
If you own the server you should use the windows task scheduler. Use AT /? from the command line to see the options.
Otherwise, from a web based environment, you might have to do something nasty like set up a different machine to make requests to a certain page on a timed interval.
I've used Abidar successfully in an ASP.NET project (here's some background information).
The only problem with this method is that the tasks won't run if the ASP.NET web application is unloaded from memory (ie. due to low usage). One thing I tried is creating a task to hit the web application every 5 minutes, keeping it alive, but this didn't seem to work reliably, so now I'm using the Windows scheduler and basic console application to do this instead.
The ideal solution is creating a Windows service, though this might not be possible (ie. if you're using a shared hosting environment). It also makes things a little easier from a maintenance perspective to keep things within the web application.
Here's another way:
1) Create a "heartbeat" web script that is responsible for launching the tasks if they are DUE or overdue to be launched.
2) Create a scheduled process somewhere (preferrably on the same web server) that hits the webscript and forces it to run at a regular interval. (e.g. windows schedule task that quietly launches the heatbeat script using IE or whathaveyou)
The fact that the task code is contained within a web script is purely for the sake of keeping the code within the web application code-base (the assumption is that both are dependent on each other), which would be easier for web developers to manage.
The alternate approach is to create an executable server script / program that does all the schedule work itself and run the executable itself as a scheduled task. This can allow for fundamental decoupling between the web application and the scheduled task. Hence if you need your scheduled tasks to run even in the even that the web app / database might be down or inaccessible, you should go with this approach.
You can easily create a Windows Service that runs code on interval using the 'ThreadPool.RegisterWaitForSingleObject' method. It is really slick and quite easy to get set up. This method is a more streamlined approach then to use any of the Timers in the Framework.
Have a look at the link below for more information:
Running a Periodic Process in .NET using a Windows Service:
http://allen-conway-dotnet.blogspot.com/2009/12/running-periodic-process-in-net-using.html
We use console applications also. If you use logging tools like Log4net you can properly monitor their execution. Also, I'm not sure how they are more difficult to maintain than a web page, given you may be sharing some of the same code libraries between the two if it is designed properly.
If you are against having those tasks run on a timed basis, you could have a web page in your administrative section of your website that acts as a queue. User puts in a request to run the task, it in turn inserts a blank datestamp record on MyProcessQueue table and your scheduled task is checking every X minutes for a new record in MyProcessQueue. That way, it only runs when the customer wants it to run.
Hope those suggestions help.
One option would be to set up a windows service and get that to call your scheduled task.
In winforms I've used Timers put don't think this would work well in ASP.NET
A New Task Scheduler Class Library for .NET
Note: Since this library was created, Microsoft has introduced a new task scheduler (Task Scheduler 2.0) for Windows Vista. This library is a wrapper for the Task Scheduler 1.0 interface, which is still available in Vista and is compatible with Windows XP, Windows Server 2003 and Windows 2000.

Send Jenkins notification only when new test fails

I have Jenkins project that perform some sort of sanity check on couple of independent documents. Check result is written in JUnit XML format.
When one document test fails, entire build fails. Jenkins can be simply configured to send email to commiter in this situation. But I want to notify commiters only when new test failed or any failed test was fixed with the commit. They are not interested in failed tests for documents they have not edited. Email should contain only information of changes in tests, not full test report. Is it possible to send this kind of notification with any currently available Jenkins plugins? What could be the simplest way to achieve this?
I had the same question today. I wanted to configure Jenkins sending notifications only when new tests fail.
What I did was to install email-ext plugin.
You can find there a special trigger that is called Regression (An email will be sent any time there is a regression. A build is considered to regress whenever it hasmore failures than the previous build.)
Regarding fixed tests, there is Improvement trigger (An email will be sent any time there is an improvement. A build is considered to have improved wheneverit has fewer failures than the previous build.)
I guess that this is what you are looking for.
Hope it helps
There's the email-ext plugin. I don't think it does exactly what you want (e.g. sending only emails to committers who have changed a file that is responsible for a failure). You might be able to work around that/extend the plugin though.
Also have a look at the new Emailer, which talks about new email functionality in core hudson that is based on aforementioned plugin.
