NewBie's Corner Session 18 Caché or Cache

NewBie's Corner Session 18 Caché or Cache

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

Caché and Cache

Caché and Cache are not the same. Caché is a product offered by InterSystems. Whereas Cache refers to memory storage.
In computing, a cache /ˈkæʃ/ KASH, is a hardware or software component that stores data so future requests for that data can be served faster; the data stored in a cache might be the result of an earlier computation, or the duplicate of data stored elsewhere.

a.k.a.. "The World of Widgets Returns!" or "Paternity leave damages Instructional Series momentum"

In our last lesson, we combined 2 separate classes to appear as the same property. We now have the ability to Update our Widget catalog, but what if we want to Create a Widget? Thankfully, we've already done 90% of what we need, just by implementing Edits

With the recent release of macOS 10.15, Apple has tightened its control mechanism , called Gatekeeper, so that it now requires executables to be notarized. InterSystems products are not currently supported for use on macOS 10.15 and the executables have not been notarized. (As a reminder, InterSystems products are supported on macOS as a development platform only.)

Hi developers,

We have just published an update to the Deltanji version control extension for Visual Studio Code.

When used in certain Deltanji workflows, triggering an automatic checkout on first keystroke could result in the developer working on an outdated copy of the code and only being notified of this later when saving their changes. In order to prevent this from happening checkout now reloads the document immediately.

Error messaging has been improved in two areas - when attempting to cancel code that is not checked out, and when trying to register new code onto a withdraw system.

We have also improved interoperability between the Deltanji extension and the InterSystems ObjectScript one, as well as its handling of multi-component objects.

If you're already a user of Deltanji then your extension with automatically update. You can find out more information on Deltanji and the latest release here.

How to overload methods in ObjectScript

InterSystems FAQ rubric

The InterSystems ObjectScript language does not allow you to define methods of the same name with different arguments. It is generally classified as a programming language called a dynamic language.

In ObjectScript, you can freely control which arguments are used when executing a method, so unlike languages ​​such as Java, which are not dynamic programming languages, there is no need to strictly distinguish methods by the number of arguments at the compilation stage.

Introduction

With the growing popularity of smart phones and tablet computers, consumers are coming to expect that software solutions will be presented as "apps" on their mobile devices. The challenge for most application developers is to find ways to make their existing solutions run on modern mobile platforms without incurring the delay and cost of a complete rewrite.

Tipy a Triky s Caché

Tip dvacátý šestý: objekty a concurrency 2 - swizzling

Když tento seriál před několika lety začínal, byl jeho první díl věnován zajištění izolace instance objektů pro exkluzivní přístup a popisu příslušných API funkcí. Nedávno se mi ale stalo, že mě tento díl dostihl. Jeden ze zákazníků začal mít problémy v aplikaci, přestože důsledně používal exkluzivní zámky pro editování instancí svých objektů.

An effective source control solution allows organizations to manage complex codebases, facilitate seamless collaboration within development teams, and streamline deployment processes.

Sonic Healthcare, a leading provider of pathology, radiology, general practice, and corporate medical services, has significantly enhanced visibility and control over its complex environment by implementing Deltanji source control. The tight integration Deltanji provides with InterSystems IRIS and IRIS for Health has been central in achieving these improvements.

New to Python. Attempting to use pypyodbc to select data from a table in one Cache database, and inserting into a similarly configured table in another. Process works fine except for tables containing Date types. NULL values in date columns are handled without issue, but when data is present, insert fails with:

An error occurred: argument 7: TypeError: 'NoneType' object cannot be interpreted as an integer.

NewBie's Corner Session 15 Executing Routines and Labels

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

Routines and Labels

Routines are computer programs with a number of executable code lines.

Labels (also called tags) are points in a routine that can be called (executed). They subdivide routines into manageable modules (or subroutines).

Points to remember before you start:

  1. It is not possible in a COS (Caché Object Script) job/process context to have multiple Named Pipes. It is a one Named Pipe per job/process limited line of communication.
  1. Named Pipes, in Caché, like most pipes on most operating systems are Unidirectional. That means you open them for either Read or Write, but not both.

If you have an app that uses some Caché client Windows components that are not included into CacheODBC distribution (e.g. CacheActiveX.dll), you need to proceed Caché client installation on end user's client computers and/or MS Terminal Servers. Being a part of Caché client's installation, Caché Cube is installed along with other components and is autostarted with every user's session. So, it becomes visible to every user.

To make it completely invisible, you can just move CACHE.lnk file from

In this series of articles, I'd like to present and discuss several possible approaches toward software development with InterSystems technologies and GitLab. I will cover such topics as:

  • Git 101
  • Git flow (development process)
  • GitLab installation
  • GitLab Workflow
  • Continuous Delivery
  • GitLab installation and configuration
  • GitLab CI/CD
  • Why containers?
  • Containers infrastructure
  • GitLab CI/CD using containers

In the first article, we covered Git basics, why a high-level understanding of Git concepts is important for modern software development, and how Git can be used to develop software.

In the second article, we covered GitLab Workflow - a complete software life cycle process and Continuous Delivery.

In the third article, we covered GitLab installation and configuration and connecting your environments to GitLab

In the fourth article, we wrote a CD configuration.

In the fifth article, we talked about containers and how (and why) they can be used.

In this article let's discuss main components you'll need to run a continuous delivery pipeline with containers and how they all work together.

This is a lesson learned, which I would like to share with community.


Recently I ran into an issue, where I was using %ConstructClone and it kept cloning extra records, which were not needed. The record for which I was trying to run a clone had many-to-one relationships.

The solution to this issue was using param -1. If you run %ConstructClone(-1) it will not clone relationships, but rather just clone single oref as desired in this case.


I hope this information helps someone who is working with similar records.

gj :: locate was the entry from George James Software for the Developer Tools competition back in April 2021. When an ObjectScript error is reported, gj :: locate takes the .int line location and navigates you directly to the line in the source file where the error originated. Over the past few months we've found it a very useful tool when it comes to debugging, especially when used alongside the Serenji debugger in Visual Studio Code.

Our first update, version 1.1.0, now includes support for multi-root workspaces. This enables gj :: locate to be used with every workspace folder. If your VS Code workspace has more than one root level folder, connecting to different namespaces or perhaps different servers, then gj :: locate will determine which workspace folder is current and locate the source code in that folder. If your workspace doesn't have any files open then gj :: locate will prompt you to select a folder from a pick-list.

This will particularly benefit VS Code power users who have workspaces with simultaneous connections to multiple namespaces, on multiple different IRIS and Caché servers.

If you would like to try it out then you can download it from the VS Code marketplace. Or if you’re already a user, then gj :: locate will automatically update. Let us know how you're getting on with it!
