Debugging

Syndicate content 10 

We at George James Software are pleased to announce that our acclaimed code debugger and editor Serenji is now available as a Visual Studio Code extension.

As well as supporting the latest InterSystems IRIS platform Serenji also works with earlier platforms, including versions lacking the server-side Atelier API support required by other VS Code extensions.

Serenji connects you directly to the code in your namespaces, resulting in an experience more familiar to existing Studio users. No need to export and import classes and routines.

We believe Serenji is the first extension to bring VS Code's powerful debugging features to ObjectScript developers.

The %Net.SSH.Session class lets you connect to servers using SSH. It's most commonly used with SFTP, especially in the FTP inbound and outbound adaptors.

In this article, I'm going to give a quick example of how to connect to an SSH server using the class, describe your options for authenticating, and how to debug when things go wrong.

Here's an example of making the connection:

Hello,

 

Last weekend we've updated our Caché version to 

Versie:Cache for Windows (x86-64) 2018.1.1 (Build 312U) 

 

I'm using Studio to develop. I've been using the built-in debugger and it has been working nicely. But now, since the upgrade, I'm getting this error when trying to debug any routine or class method:

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.

At the George James Software booth at Global Summit last year we took the wraps off the work we've been doing to make our popular editing and debugging tool Serenji available on the Visual Studio Code platform.

Rather than requiring you to pull code from your namespaces into local files, then push the changes back to the namespace to run it, you work directly in the namespace. In other words, the editing experience is like Studio rather than like Atelier.

As well as editing code you can also debug it directly from VSCode.

I've been looking at the idea of developing a Time Travel Debugger utility.

It would take a debug target and have a few options such as stack depth and disclude system code.

The debugger would either be started from an external tool, or triggered from a line of code inserted into a method that I want to record.

The debugger would execute the code from start to end and record the full stack on each step to the configured depth.

Not everyone knows that InterSystems Caché has a built-in tool for code profiling called Caché Monitor.

Its main purpose (obviously) is the collection of statistics for programs running in Caché. It can provide statistics by program, as well as detailed Line-by-Line statistics for each program.

Using Caché Monitor

Let’s take a look at a potential use case for Caché Monitor and its key features. So, in order to start the profiler, you need to go to the terminal and switch to the namespace that you want to monitor, then launch the %SYS.MONLBL system routine:

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

Using our cool new debugging extension for Visual Studio Code I'm trying to debug a CreateProjection method of a class, but when I compile it the work apparently gets done in one of the worker jobs, so my breakpoint never triggers.

Is there a compiler flag or qualifier to force the compilation to be done in-process rather than getting handed off to a worker job?

The code I'm researching loosely follows this flow:

  1. My first callback
  2. Black box
  3. My second callback

I can modify 1 and 3 no problem but modifying 2 is difficult.

However I think that step 2 has some optimization problems, namely:

  • instantiates lots of objects
  • throws/catches lots of exceptions (not logged)

Is there a way to count these two metrics?

Hello all, I created a web service and I am trying to access it using SoapUI but I get this error:

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;

One of the most important features during application development is the ability to debug your code easily. Because of the asynchrnous nature, a standard Node.js application server works single-threaded by default. When you are developing applications using an IDE like Visual Studio Code, you can very easily debug your Node.js process:

First, download the free Visual Studio Code IDE (@code) and install it on your development machine.

We have a large number of processes and operations being applied to outbound HL7 messages from our PAS.

If I select a message, and open its visual trace, I see the service, as well as all processes, and operations. 

My debugging is often about a new operation, and I don't need to see all the other operations that are in functioning as desired.

I am running a ZBREAK trace on a legacy FDBMS application that uses arrays but rather than displaying the array value contents, I am seeing logs similar to the following.

Trace: ZBREAK SET LINE=Array Val at BIOPWR+6^BIOPWR

My ZBREAK trace settings are as follows:

Hi,

How can I read the stack of another process?

I know about ^JOBEXAM, but I only know how to use through terminal, and I need to get a string, or at least do a method that returns me a string

For example:

I have process A and B

B monitors process A at each second.

B logs information about process A in a table

Informations about lock I get through %SYS.LockQuery and the process through %SYS.Process

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.

Cache Studio almost always crashes when I click rows in Call Stack view during debugging. Then Cache has to be restarted because last edited file remains locked.

Looks like I'm the only one who uses the debugger. Or is there a magic spell to make stack view working?

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.

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?

Hi,

I have a process that is importing lots of data from an external file, but every now and then I come across a STORE error.

I know that the STORE error is occurring in the %Save method of the class but I know very little else and I think its something to do with a lage amounts of Related Objects.

Is there a method of finding out more information regarding this error i.e. which actual object was being saved etc etc.

Thanks

Jim
