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.

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.

Debugging Web

In this article I'll cover testing and debugging Caché web applications (mainly REST) with external tools. Second part covers Caché tools.

You wrote server-side code and want to test it from a client or already have a web application and it doesn't work. Here comes debugging. In this article I'll go from the easiest to use tools (browser) to the most comprehensive (packet analyzer), but first let's talk a little about most common errors and how they can be resolved.

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)?

Global-Streams-to-SQL

In general Global Streams are data objects embedded in Classes / Tables.
Using and viewing them with SQL is normally a part of the access to the containing tables.

SO WHAT?

During debugging or searching for strange or unexpected behavior there could be the need to
get closer to the stored stream. No big problem with direct access to Globals with SMP or Terminal.
But with SQL you are lost.
So my tool provides dynamic access to Global Streams wherever you may need this
Special thanks to @Oliver Wilms for the inspiration for this tool.

Global-Streams-to-SQL #2

Some technical background information

There is not just one class in this package: rcc.gstream.cls but also rcc.gstreamT.cls

While rcc.gstream works with direct access to the stream globals, the *T version uses
a Process Private Global (PPG) as Temporary storage.
using SELECT * FROM RCC.gstreamT WHERE RCC.useT('^jpgS')=1 and similar.

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.

This enhanced debugger also takes advantage of the latest features of VS Code itself. With this powerful combination you'll be able to smoothly identify and quickly fix errors in your code, contributing to the production of quality, maintainable code... and isn't that what everyone wants?!

In this latest release you will experience:

  • Debugging in just one click with zero configuration.
  • Navigation directly to the source of an error using our gj :: locate technology.
  • Intuitive prompting for entrypoint and arguments.
  • Configurable break on error.
  • Program output in debug console.
  • Run and Debug CodeLenses.
  • Run multiple concurrent debug sessions and consoles.
  • Shaded background for read-only documents.

If you're a new user, it's now easier for you to get started. The introduction of a welcome page Walkthrough and guidance on the Explorer and Run and Debug views means you can effortlessly create your initial workspace and start debugging.

Download Serenji directly from the VS Code marketplace and take a look at our release notes to find out more about these new features and how to use them.

We offer a free 30 day trial so if you're not yet a user of Serenji but you're interested in how it can help you, drop me a message through the Developer Community or email us at info@georgejames.com.

Happy debugging!

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.

In the interactive debugger window:

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;

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"

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.
