#Debugging

Debugging is the process of finding and resolving defects or problems within a computer program that prevents the correct operation of computer software or a system.

Hi Everyone,

New Coding Talk, recorded by @Evgeny Shvarov, is already on InterSystems Developers YouTube:

Hi I'm hoping the community will once more help me out with a question!

Right I have a production that takes an attachment from an email and processes it, sending out a hl7 message at the end. This works ok.

Now I just need to take the email and send it back out to a 'backup' email address, basically giving
a) A backup incase there is a problem with the email or something else further down the line.
b) A log of the emails receieved.

So I thought the best thing to do is have an operation with an email adapter and to send that my message.

Exported contents of a namespace on one server (classes, include files and lookup tables). Importing that code into a newly created namespace on another server. Both servers Ensemble 2018.1, same build. Export was via InterSystems Studio. Export is around 18Mb in total (XML file sizes).

When importing and compiling on the new server, getting errors as below - with #6301: SAX XML Parser error prominent - on a number of the imported files, all containing data transformations or business processes.

I have multiple projects that I utilize when debugging in Cache Studio. One of my projects suddenly lost the ability to step through commands with the yellow box and the cursor moving though code lines. The cursor just sits at the entry line while variables apparently do change. Interestingly enough, if I change the project and the debug target, the "yellow box" ability is still there. Apparently losing this functionality is by project/debug target/whatever. The goal is, of course to return it back but how?

Hi

How do I view the .int code of a compiled class in VS Code?

I am trying to use gj::Locate and the setup works, the explanation is all fine but when i paste an error from the Error Logs into the gj::locate it firstly tells me that it can't find the .cls and when I paste in the .int reference in the text box where you can specify the class, method, line+offset it replies that it can't find the item.

This is something to do with the objectscript extension rather than gj::locate

Debugging in HealthShare

Hi, if you develop production with HealthShare, you may have noticed there is a nice tracing feature available - HS.Util.Trace.Operations. This feature allows visually tracing debug information, in structured way. It complements good old logging macros like $$$LOGINFO, $$$TRACE and alike.

I use this feature a lot. However, it has limited functionality, it works nice with classes that extend XML Adapter, streams or data types, but it doesn't work well with arbitrary objects that do no extend from XML Adapter.

Hello

I recently spent some time with Atelier, and tried to use it's inherited (from Eclipse) XSL transformation capabilities.

I have installed Exlipse XML Editor and Tools and Orangevolt XSLT - as it provides Saxon XSLT processor.

I have XSLT 2.0 transformation defined, that uses isc:evaluate() callback function to perform some server side code.

And here is my problem: when I try to run XSL transformation of a file in my project, then as soon as the processor hits isc:evaluate() it fails.

While I love using VSCode for IRIS development work, one of the persistent frustrations with it has been the inability to display an object hierarch in the variables window while debugging. Only the object's reference identifier is displayed. Cache Studio's handling of the same issue is a little clunky, but it does at least have the option to display something as an object.

For now, I make do with a combination of the watch window and the command line in the debugging console -- but this feels just a step away from log.debug()/console.log() level debugging sometimes.

The article makes an attempt to demonstrate that Atelier is not just repeating the functionality of Caché Studio on a new IDE platform (Eclipse) but goes far beyond. Due to my personal experience, and challenges in former projects I picked first XSLT Debugging. Is it an ordinary task? Not at all. Who is doing XSLT every day? Probably none of us. Than why XSLT Debugging? Simply because there are solutions in our product portfolio which are using XSLT inside and those solutions require customization. Customizing XSLT without some sort of toolkit is more than challenging. The examples of such solutions starts with HealthShare IHE message, CDA vs. SDA transformations, goes through ZEN Reports, and ends by HealthShare CDA document viewer. Is that enough reason to spend time reading the whole article through not just the teaser?

Our development server is set up to automatically keep the .INT code of compiled classes and routines, but the live servers are set to not keep the .INT code.

I know how to set the system to keep this code ($SYSTEM.OBJ.SetQualifiers() ?) but what are the ramifications of keeping this code on the live servers? Is it just a space issue? I always thought it was to keep the code more private.

WebTerminal : blank screen

I just downloaded and installed the latest WebTerminal into my local copy of Healthshare 2016.2.1

I installed via studio and everything compiled without error.

However when I run it I just see a black screen. The help window at the bottom of the screen pops open when I type '/' but I just can't get any response.

Any suggestions as to how to trouble shoot this?

Mike

Hi,

I'm getting thousands of errors like the ones below:

VS Code Related Resources

Following 2 local Webinars we had focused on VS Code ["Intro" and "Beyond Basics"; in Hebrew], I prepared for the participants some related links of relevant resources which we sent as a follow-up. Sharing them here as well for the benefit of the Community.
You are all of course welcome to add more useful resources.

Uninstalling Ensemble

On a developer's laptop, having had two or three Ensemble installs with different settings/config changes made, and encountering unexplained errors compiling classes, wanting to scrub as much of the previous installs off the machine before doing any fresh installation... But can't find clear documentation on doing a complete uninstall!

Have stopped the server.

Am I safe to remove C:\InterSystems\Ensemble (for the instance installed into that folder)?

Hello,

I don't know if the title is accurate enough. I have a legacy code that I need to optimize. It's a routine written in objectscript. It accepts 4 parameters and runs 6 nested FOR...$ORDER reading a big global.

The thing is when I run the routine the first time it takes around 60 seconds to run. If I run it again it takes 5 seconds. If I wait around 6 to 10 minutes to run it again, it takes 60 seconds again, but if I run it every 1, 2, 3... minutes it still takes only 5 seconds to run.

Intro

If you ever wondered how to debug some requests that are being made to or from IRIS, well here is a little tutorial on how to do that.

During a complex project, usually you get the specifications and implement the communication between IRIS and other things based on that. But from the paper to the real world there's usually a huge gap and you need to know why you are receiving an error on a parameter, on a header, you are not receiving the data and so on.

Debugging Business Operations

Often we need to debug a Business Operation. Tracing and logging work but sometimes you want to work with a BO as with your local terminal session.

Here's how you can do that on any operating system.

Windows has a great tool for debugging Business Operations - Foreground mode. In that mode Windows launches a local terminal with operation job.
