Hello!

I am trying to install Caché 2016 on a Debian Jessie machine; so I downloaded the latest release from WRC, OS RHEL x86_64, in tarball format.

I untarred it, then launched cinstall; unfortunately a library was missing. I then elected to kill all the processes (which wasn't easy), remove the two users created, and start again.

Unfortunately, for some reason, when I relaunch the install again, the install process still detects the old instance which I installed previously.

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?

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.

This is rather convenient in my situation, sure; but is there another way which does not require such privileges?

Hello,

I am still a beginner with COS and am struggling with these concepts. While digging through the official documentation will eventually tell you everything you need to know, getting started is nevertheless not an easy feat...

Is it possible to create a "lists/array/multidimensional 101" page for beginners?

Hello,

Here's the code:

Method isTestClass(className As %String) As %Boolean
{
	if (className = .#UTCLASS) {
		return 1
	}
	
	#dim c as %Dictionary.ClassDefinition
	#dim status as %Status
		
	set c = ##class(%Dictionary.ClassDefinition).%OpenId(className,,.status)
	
	if ($$$ISERR(status)) {
		throw ##class(%Exception.StatusException).CreateFromStatus(status)
	}
	
	if ('c.SuperIsDefined()) {
		return 0
	}
	
	#dim children
	#dim len as %Integer
	#dim i as %Integer
	
	set children = $listFromString(c.

Hello community!

Heretofore is announced a new project which aims at providing a usable library for both running unit tests and collecting code coverage information at the same time:

https://github.com/litesolutions/cache-utcov

I shamelessly admit that this is my first project written in ObjectScript; the only source file right now barely loads a %Studio.Project instance on a given namespace and fails ungracefully on failure (it HALTs; meh); and even on success it will not even list the items correctly.

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:

• grab the project (by name, I

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)

Side note: that would be a good opportunity to launch a project of an IRC bot in COS.

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 :/).

Is there an existing source which I am missing?

Hello everyone,

I have discussed extensively with Andrew Cheshire, the author of the Atelier parser (which I'll be able to hack on and reuse for CachéQuality -- yay!), and while we were at it, we also discussed code coverage.

We ended up talking about the ZBREAK command and its /TRACE option.

It appears that combining this command and the unit test runner, we can indeed do code coverage (Andrew also told me about a way to map "back" routine lines to original lines in the source code).

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!

Hello community!

Two new rules have been implemented:

OS0061: unsafe namespace switch

This rule detects when the body of a method contains two or more of the following statements:

• set $namespace = something, or
• znspace something.

If this is the case, it then checks whether there is a new $namespace prior to those two declarations; if not, it raises a warning.

List of issues currently found here:

Hello community!

At the global summit in Phoenix, we (Lite Solutions) will be presenting a tool performing static code analysis on ObjectScript source files. You can see it in action at this URL:

https://demo.cachequality.com

Technically, the tool is a language plugin over SonarQube (http://sonarqube.org) and consists of three main parts:

• parsing the language,
• collecting metrics,
• collecting issues.

The third point is where we kindly request for feedback.

Explanation: issues are the result of rules being triggered by inspecting the source files.

Hello,

This package may be of interest...

Link: https://github.com/litesolutions/cachedb-import

I have programmed this over a hunch, in order to facilitate the retrieval of source code from a Caché installation. It makes use of the Java API provided by Caché.

Right now, I use it as a means to salvage sources in order to analyze them using the SonarQube plugin I develop for my employer. Unfortunately this plugin is not open source.

I am calling for help here, on two fronts:

• improve the code,
• obtain source samples to analyze!
