#Debugging

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)?

What other files/Registry/locations contain references to an Ensemble install, and are there tools or documentation on clearing those out?

Visual Studio Code (VSCode) is the most popular code editor on the market. It was created by Microsoft and distributed as a free IDE. VSCode supports dozens of programming languages, including ObjectScript, Until 2018, Atelier (based on Eclipse). It was considered as one of the main options to develop InterSystems products. However, in December 2018, when the InterSystems Developer Community launched support for VSCode, a relevant portion of InterSystems professionals started actually using this editor and have been doing it ever since, especially the developers working with new technologies

Hey all!

I was wondering if anyone had any input on how to troubleshoot classes in a terminal session? I'm currently writing an "adapter" so that way we can encrypt and decrypt files through GNUPG (PGP keys).

I currently have a %RegisteredObject class for this and am running into the excruciating pain of testing this. Every time I make a change on the RegisteredObject I have to renew the class and all of its properties in order to test the newly compiled code that I have written. I know that this doesn't seem like too much of a hassle, but after doing it multiple times it becomes tiring.

Is there a way of comparing code running on two Ensemble servers - ideally excluding certain types of difference?We are a new team working in HealthCare (lots of HL7, some web-services). As well as doing new development on local servers with suitable source control, we have a large code base we've inherited from an external supplier for which we have no log of versions or differences. We have a live server and test server - and we've stumbled across a couple of places where there are differences in logic in addition to the expected differences in endpoints. Is there any way of systematically

Very simple, how to debug? The settings recommended in the docs don't work. I need a convenient way to keep track of what a function returns, like in other languages, by displaying it in the console.

When I try to debug using the docker image intersystemsdc/iris-community it is failing. If I change to intersystemsdc/iris-community:2022.3.0.555.0-zpm, I have success.

Sorry, change to: intersystemsdc/iris-community:2022.1.0.209.0-zpm

I am currently trying to better my development process by using Visual Studio Code because I'm more familiar and comfortable with it than Studio.

I've followed the guide here, but I'm still having issues. I initially didn't have the Web Socket protocol allowed on my Web Gateway server, but I enabled that and restarted the server with no luck.

Am I just on too old of a version? Is there any way I'd be able to use Visual Studio Code and be able to debug with what I currently have? I wish I could upgrade to IRIS, but that doesn't seem to be an option.

Folks!

Could you please share any best practices on how to debug Embedded Python code?

Given I have the following class method:

ClassMethod HideShip() As %Status [ Language = python ]
{
    import iris
    shipsgl=iris.gref(iris.cls(__name__)._GetParameter("BoardStorage"))
    shipsgl.kill()
    from random import Random
    board=iris.cls(__name__)._GetParameter("BoardRange")
    x=random.randint(0,board+1)
    y=random.randint(0,board+1)
    shipsgl.set([x,y],1)
}

And when I run it shows the following error:

Hi developers, 

We're excited to let you know about the latest release of Serenji, your on-the-spot debugger from George James Software. Version 3.2.0 focuses on the debug experience and introduces zero configuration for users. No matter where you are or what you're doing, Serenji is always ready to go in just one click, so you won't lose focus by spending time setting up a launch configuration. 

Issue

Breakpoints do not work when using VS Code Debug this method feature on a ClassMethod. Debug runs like normal and I can sometimes see 'running' on the CALL STACK menu. In the BREAKPOINTS menu, the breakpoints will start red, like normal, but eventually turn gray. On-hover for a grey breakpoint is the message "Breakpoint Cannot Be Mapped". After the method finishes, the breakpoint turns red again. No error messages appear. This is an intermittent issue, as sometimes it runs fine. So far, I have not been able to figure out the conditions to re-create this issue.

Any suggestions?

Edit: 

I've faced a problem that happens while debugging a process in VSCode. It doesn't seem to matter if this is in a container, on my development VM, or against a locally installed version of IRIS. The problem seems to be mostly with X12 Documents.

So, in a debug session, I can dump out a value to the debug console and it loos correct. The same variable in VSCode appears to be some uninitialized memory location.

Hi Community,

I would like to share with you my experience regarding  to debugging via Atelier.

I'm developing a REST API and would like to attach to a process when I call the API via a REST Client tool, for example Postman. The purpose is to inspect values from HEADER and BODY of the HTTP request during the debugging process.

Come on! How am I doing? I am going to demonstrate that by using a class from SAMPLES namespace.

1 - Open Atelier;

2 - Open your REST Service class;

3 - Go to the method related to the URI that you need to debug;

Hi community!

I'm using Insomnia software for testing my REST applications from cache and wanted to know how do I debug POST that got sent into backend by this tool via json sent from the request body!

I'm using 2018 cache and running tests by VSCode
thanks for any help

There is a popular package "WebTerminal". It is excellent in most situations.
Except:

From time to time, we get the previous question in support, something or someone is using more licenses than expected, and we need to find what. 

We have two scenarios. The first scenario is when we realize that the licenses are exhausted when the application does not work or when we try to connect through the terminal and get the "lovely"

Hi,

Is it possible to use the IRIS' Interoperability's Foreground Window option for Business Operations when IRIS is running in a docker container ? 

Thanks -

Hi Community,

When we terminate a process that is in a transaction, the system (fortunately) performs a rollback.

As part of some troubleshooting, I'm wondering if there's a way around this behavior to avoid rollback (or force commit) before termination.

Recently we had an issue on a test server with a process stuck in a huge transaction (around 100GB).

The out-of-control process was suspended and then terminated causing a rollback.

In the case of a test server, this is not really a problem.

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.

Hi, Community!

Want to share with you one debugging approach from the Russian forum.

Suppose I want to debug the application  and I want it to stop the execution on a particular line.

I add in code this line:

l +d,-d

When I want to start debugging in this line I block d in terminal

USER> l +d

And execute the app.

The app stops on this line and lets me connect to it with Studio debugger.

To release lock I do in terminal

USER> l -d

And what are your debugging practices?

How I do send the output of zwrite to $$$TRACE()?

I am experiencing a problem with an EDI process that uses a SQL Batch Service to connect to our DEV environment.  However, when we point the EDI service to our TEST server, it errors out.

I have checked every single property on our TEST and DEV servers as well as the properties on the associated tables.  They are identical.  Nothing has changed in the SQL either.

How can I do to debug IRIS docker instance into VSCode?

I would like to watch a webseminar about debug objectscript techniques into vscode to rest api, productions and embedded python, specially using docker instances and remote servers.

InterSystems technologies are renowned for their high performing databases, which support the systems and operations of many organisations. However a key ingredient to this success is the quality and maintainability of their code. 

The quality of code can impact everything from speed and ease of fixing bugs and making enhancements, to the overall performance of your organization and your ability to get ahead in the marketplace. 

Ladies and gentlemen!

Is there a way (some secret call? ) to turn on a debug mode for a particular IRIS web app?

The reason is to log debug information in REST-API dispatch methods if the app is in debug mode.

Of course, I could use "a global", but if there is any standard way?

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.
