I'm trying to read the response to a long (indefinitely) running HTTP response with Transfer-Encoding: chunked. Ideally I'd be able to read the individual chunks from the response and do something with them as they arrive rather than needing to wait for the response to finish (because it never will) - ultimately I'm thinking to wrap these back up over a WebSocket connection which seems cleaner from an API perspective.

So far it looks like my options are:

Looking at the documentation, I see that the global ^ROUTINE brings the information and code of the .INT version of the routines. However, I would like to know where the equivalent information of the .MAC version is, as I did not find any reference to this in the documentation.

Some information in the .MAC version are hidden or already converted into the .INT version, and I would like to have access to this information through the system, and not just opening the routine in the studio.

Hey all,

I have been creating a class to handle file encryption by using GPG keys. I pushed my code out today and my encrypt and decrypt methods weren't working. About a half an hour later in troubleshooting I found out that it needed to be a syntax change. My method has three parameters to it. Examples below:

This is how I was calling it in the test system with no issues:

do gpg.Encrypt()

This is how I was having to call it in my production system to work with no issues:

do gpg.Encrypt("","","")

The question has come up several times and I saw mixed answers and no quick example

My personal preference is using CPIPE device as you get back exactly the output you will get at the command line interface of your OS .
The tricky thing is to stop reading in time.
The example just displays what you normally see in your console.
it becomes useful if you look for things that you can't get from any $system.whatever()

Hi all!

In this article I would like to review those VS Code extensions which I use myself to work with InterSystems and which make my work much more convenient. I am sure this article will be useful for those who are just starting their journey to learn InterSystems technologies. However, I also hope that this article could be useful for experienced developers with many years of experience and open up new possibilities for them when using VS Code for development.

I am looking into creating a ZSTOP as you probably have seen from my previous posts, is there a way to capture the type of shutdown that occurred? So say if there was an unknown hardware failure (forced), vs a user shutdown? Mainly looking for user or system shutdown when we force another destination to become the primary in the mirror. So if a user shutdown the production to do.,... Task A, Task B etc..

Thanks

Scott

Introduction

This article is intended to be a simple tutorial on how to create ODBC connections and working with them, since I found starting with them a little bit confused, but I had amazing people to take my hand and walk me through it, and I think everyone deserves that kind of help too.
I'm going to divide each little part in sections, so feel free to jump to the one you feel the need to, although I recommend reading everything.

Questions about using ZSTOP

I am working on setting up our Failover techniques as we move to a Mirror Environment with a Arbiter, 2 Failover Nodes, and a Async (DR) Node. There are some system commands that I would like to call when the Mirror moves, and I am working on a ZMIRROR routine for that, but I also wanted to create an additional step if we wanted to manually shutdown and for the Mirror to move. So I was looking at using ZSTOP to call a couple of different items while shutting down, while the documentation has an example a couple of questions come to mind about using ZSTOP.

? %QUERY Wizard in VSCode ?

For my recent tutorial, I used %Query Wizard of Studio.

Could any of the VSCode experts please show me how to generate

Query Statement with input parameters, CONTAINID , ROWSPEC
and the required class methods
- <queryname>Execute()
- <queryname>Fetch()
- <queryname>Close()

I was just not able to do it.

I'm wondering how I would go about adding headers to a csv file which has already been created. I am unfamiliar with ObjectScript.

For example if I were to use R, I would simply write..

test <- read.csv("file/path/example/Extract.csv", header=FALSE)
colnames(test) <- c("A","B","C","D","E")

I do not have embedded Python installed either as I would know how to do it in that also.

How could I mirror this in ObjectScript please?

My current create file method:

At least three different ways to process errors (status codes, exceptions, SQLCODE etc is given in ObjectScript. Most systems have status, but for a range of reasons exceptions are more convenient to manage. You spend some time translating between the various techniques dealing with legacy code. For reference, I use several of these excerpts. It is hoped that they will also support others.

Hi all,

I might be losing my mind or do not understand how ObjectScript does string comparisons, but the following does not look right to me.

Is it really possible that you can't compare non-numerical strings other than with an equals or not equals?

USER>w ("45" < "46")
1
USER>w ("45" > "46")
0
USER>w ("V45" < "V46")
0
USER>w ("V45" > "V46")
0
USER>w ("V45" <= "V46")
1
USER>w ("V45" >= "V46")
1

In Python:

Any ideas on how this can be solved?

I need to use it with some Unicode text, in Docker image. And get this error. And documentation says nothing about it.

USER>do $zf(-100, "/SHELL", "echo", "test")
test

USER>do $zf(-100, "/SHELL", "echo", "test тест")

DO $ZF(-100, "/SHELL", "echo", "test тест")
^
<TRANSLATE>

I know that it works in some Linux environments without Docker, but no idea where is the difference.

Hi:

I don't understand how to use this open exchange item for auto creating deleting items. I think it assumes knowledge in the steps of how to use it which i don't get.

Added the code into dev on SRFT.Utility.DeleteHelper.OnDeleteSuper and SRFT.Utility.DeleteHelper.AddHelper

Hi Community,

A long time ago, I create a package for a String datatype that works with Regular Expression. It is quite a simple solution.

This can work well with packages like the OpenAPI-Suite, where you can then use the "Regular Expression String" as the type for properties of the validator objects where the Swagger contained a Regular Expression.

I am proposing we start a common package of datatypes for use. The package name to use can be provided by the admins.
