Ensemble HTTP OnProcessInput

I am just trying to make a quick hand off HTTP production. I have the class built and compiled onto the server and the production is running as a service. When the production is called (by an inbound job) I can see that the HTTP.InboundAdapter is being used successfully and the stack continues all the up to ProcessInput where OnProcessInput is called in Ens.BusinessService.

NewBie's Corner Session 4 The Plus Sign and Concatenation Operators

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

Click on the Caché Cube in your system tray and select Terminal to try out the commands.

Plus Sign (+) operator

Typically, the Plus sign (+) adds two numbers together. This is true in COS (Caché ObjectScript), but COS uses it in other ways as well.

Set the variable X to a value of +12

NewBie's Corner Session 2 Variables Set and Write commands

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

Session 2 – Click on the Caché Cube in your system tray and select Terminal to try out the commands.

Variables

Like other computer programming languages, Caché uses Variables and the values they represent to control programming. Variables are elements that represent data values. Manipulating and interrogating variables is at the root of programming.

Hello,

I'm trying to connect to a Caché server from Atelier; the Caché server is 2015.x.

The address and port I'm trying to connect to is the SQL gateway server; and I get, each time, an "unexpected end of file from server".

Note that unfortunately, for the moment, I connect as _system... And the Caché install has the default privileges.

What am I doing wrong?

mySQL data importer tool

Hi,

If you want to import data from a mySQL export file (exported with mysqldump), you will find here a little script that could help.

Only the INSERT commands in the sql file are executed into Caché. Indices are not computed for better performance.
%NOINDEX, %NOCHECK and %NOLOCK are generated on each INSERT line.

Currently, the file can not contain a "),(" pattern inside the values part of the INSERT command. If this is the case, the line is skipped. This feature may be implemented in the extractValuesList method.

Hi!

Want to share with you code snippet of try catch block I usually use in methods which should return %Status. 


{ 
 try {
  	$$$TOE(sc,StatusMethod())
 }
 catch e {
 	set sc=e.AsStatus()
 	do e.Log()
 }

Quit sc 
}

Here $$$TOE is a short form of $$$TROWONERROR macro.

Inside macro StatusMethod is any method you call which will return %Status value. This value will be placed into sc variable.

Hello,

It is time for me to eat my own dog's food and start implementing unit test running with coverage :) I will be inundating IRC with questions at this point, but I have a more general question first.

In this tutorial, it is supposed that your unit tests are exported as XML first... But that's not very practical. Is there a way, instead, to run all tests from a given project without having this export?

My first thought on how to do this would be to:

Hello,

Still related to the unit test with coverage support project, one goal is to make that package available to everyone.

One possible way I already know of is that all fully qualified class names (ie, the package + the class name) start with %, which mean that on installation all classes will end up in the %SYS namespace, but this requires that the install be done as a user with the necessary privileges to write to %SYS.

Hello,

For CachéQuality I'd love to be able to create issues when the programmer uses classes which are deprecated for this or that version of Caché... But short of reading all the changelogs of all versions, I can't really tell when a command appeared (for instance RETURN; I know now that it appeared in 2014.x, but it took me some time to realize that), or when a (set of) class(es) became deprecated (for instance %GlobalCharacterStream to be replaced with %Stream.GlobalCharacter -- I don't even know since which version this is true :/).

Hello,

I hereby announce the creation of an IRC channel dedicated to Caché development:

* network: FreeNode (connect to server: irc.freenode.net)

* channel: ##cos (yes, two hashes).

Topic is anything related to Caché development in spite of the name (and the fact that of Caché development I only really know about COS anyway), so sorry in advance for the restrictive channel name :)

Waiting for you here! (my nick is idletask on freenode)

Hello!

Link: https://demo.cachequality.com

In this presentation, developer oriented, we will cover this tool, how it works, how you can use it/administer it, etc. Duration 30 minutes.

The topics will include:

  • a short presentation of Caché Quality and SonarQube (which this plugin uses),
  • a demonstration of the rules and how to tailor them to your need.

Questions will be more than welcome! Hope to see you there!

And a big thanks to Evgeny Shvarov who made this possible!

This morning on the old Caché Google Group, someone posed the following question, which I've decided to answer here, because it's interesting!

Is there a way to iterate ClassMethod's params, and get param's names and values?

The first answer I can come up with is: it's not easy! In any method, you could try to write code like this (where methodName is the name of your method):
