#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.

Hello,

I have a couple of IOT devices that communicate via WebSockets to our backend.

I successfully managed to create a websocket connection between server and (iot)client using %CSP.WebSocket
However I would like to implement authentication on this using the HTTP headers at the same time of Connection: Upgrade.

I tried to set the headers to globals in order to debug but they are always empty.

Example code:

If I open a terminal and type the following commands, sc is an error:

set validator = "sc = ##class(%Library.Numeric).IsValid(""BLAH"")"
set @validator
write sc

At the end, when I write sc I get:

0 L'BLAH9
             DOCXT010,#e^zIsValid+1^%Library.Numeric.1^1e^^^1

However, if I call the following class method using the arguments "%Library.Numeric" and "BLAH", sc is undefined

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.

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

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.

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)?

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.

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

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.

Context

I have created a Business Operation (BO) named "Sender" that sends HTTP messages to an endpoint (for testing, I'm using Postman's Mock Servers).

Goal: I want to set up an automatic timeout mechanism so that if I don't receive a response from the server within 18 seconds, an alert is generated and the message is resent. This process should be repeated every 18 seconds, for a maximum of 90 seconds. If no response is received within 90 seconds, I would like to generate an error message. On the other hand, if a response is received, I want to stop the resending process and complete the operation by indicating successful reception.

Debugging web app

Hello, I'm trying to debug web app in Atelier remotely.

In Studio I could use "Set as debug target" option for this purposes. The class launches with CSPDEBUG option in browser and everything goes fine. But I can't find how to do this in Atelier.

Can anyone help me?

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:

I am currently debugging a piece of code relying heavily on macros. I am using breaks in the method to then check the values of macros and object properties as I go. However, any time I invoke a macro within a break I get an error. To get around this I am converting the macro calls into the underlying code. Some of these macros have messy translations and this is somewhat time consuming. Is there an easier way to access macros from within a break?

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.

I am fairly new to Cache and ObjectScript. I have a new task I have created with a corresponding method that I am trying to debug in Studio (2013).

My ClassMethod looks like this

ClassMethod DoMyWork(Output pWorkCount as %Integer,  pInput1 As %Integer = 30)

{

/* Does some work here and increments pWorkCount */

}

When I try to debug this using studio, I browse to my method but I am not certain what to put in here for the input parameter 'pWorkCount'.

Hi everyone,

I have an existing application on HealthShare 2015 and decide to move it to HealthShare 2018 to make use of Atelier support. I am using Eclipse Photon with Atelier Plugin 1.3.

Most of things are working better on Atelier comparing with Built-in studio of HealthShare. However, when I tried debugging CSP file with Atelier I encounter 2 problems:

Running Cache 2017.2.2.

I'm trying to make a REST API call in JSON format. When using the example in the class reference documentation the getJSON method in the %Net.Http class throws the error <METHOD DOES NOT EXIST> on a %Clone() method in the %LIbrary.DynamicObject class. I even changed the parameter to a JSON string to no avail. The code will then fail on the %Compose method (examples below). My workaround is to use the %Net.HttpRequest functionality. Is there another workaround to this?

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.

Debugging a SOAP web-client

Pointers please for debugging a SOAP web-client.

We have several clients in different productions all accessing a web-service. We are trying to add another client in a new production, and its not working. The messages between the relevant Process and the SOAP web-client Operation are the same in the working and the non-working productions. But the web-service is reporting an XML parsing error to the non-working production. Here's the error as reported in the SOAP web-client Operation...
