Authentication with REST

We are building a bunch of rest based services using Ens 2016.2 to serve our browser based application (Angular 4).

Two questions:

1. The initial authentication seems only work if credentials are placed in the url parameters. Trying to use the Authorization header instead, the client code immediately complains about Access-Control-Allow-Origin. How can I resolve this?

2. After initial authentication, what is the proper way to send subsequent rest calls without having to include credential every time?

Drawing boxes

Hello, Community!

Here's an interesting task I found on the Internet.

Problem description

Write a method that would draw a box of a specified size.

The goal is to write the shortest method.

Here's a method signature (it can't be modified):

ClassMethod main(s As %Integer = 10)

And call sample:

>do ##class(ITPlanet.Task4).main(5)
#####
## ##
# # #
## ##
#####

>do ##class(ITPlanet.Task4).main(10)
##########
##      ##
# #    # #
#  #  #  #
#   ##   #
#   ##   #
#  #  #  #
# #    # #
##      ##
##########
 
>do ##class(ITPlanet.Task4).main(20)

To prepare a migration to IRIS I use Docker images.
The (aged) application is built around Caché Terminal
And on Windows, IRIS uses the same ctelnetd.exe as Caché.

In my Docker installation, Telnet Settings are just grayed out in SMP.
and my Terminal can't 'connect.
Port mapping is OK and verified with TCP

Working from the console in Docker with the whole set of ESC and
screen formatting is not acceptable.
We tried WebTerminal but there is just no Partition behind as in Terminal.

When I try to open a DTL in the tabbed editor I always get this error:

You are using Internet Explorer 7. This version is obsolete and is not compatible with diagram editors. Please update Internet Explorer to a recent version.

My actual Internet Explorer is version 11.

I'm running Eclipse Photon.

Atelier IDE 1.3.141 com.intersystems.atelier.feature.group InterSystems Corporation

The same error occurred with Atelier 1.2 on Eclipse Oxygen. I've never been able to get this to work.

In Atelier when resolving conflicts with the server the screen shows the Local copy and Server copy and the differences, but depending on where the difference is you cannot tell what what the document is, you need to scroll to the top to see what it is before deciding what to do. It should indicate the class or routine name beside "Conflicting Server documents"

InSync is an application currently under development by InterSystems, primarily using Ensemble, as a mixed CSP/Zen web application. There's a lot of defunct legacy code in the code base and we're actively seeking it out and trimming the deadwood out.

Get variables list

Hello!

In Caché there is a way to print all current variables using write command without arguments:

USER>set Einstein = 1879
USER>set Mozart = 1756
USER>write
Einstein=1879
Mozart=1756

But is there a way to get a list of this variables? I am looking for something that would return value like $LB("Einstein", "Mozart") for this case.

Thanks!

I have a quick question regarding swizzled objects.

I have an original object, say Object a, I am working with.

I set a property a.something.somethingother.somethingelse.myNewProperty to some value x.

Then at some point I am saving a and continuing to work with it. I assume here by saving a, I saved myNewProperty as well. (as it should work)

hi,

i have two where-clauses:

a) ... WHERE company=1 and product=7

b) ... WHERE product=7 and company=1

with other words the position of the where fields are swapped.

now the question is:

bring the where clauses a) and b) the same performance(queryplan) or do i have to write it in a special order???

in my point of view, there is a parser/optimizer who cares about this, so i don't have to care about.

If two globals have same structure, how to reuse one CacheSQLStorage-based class to read both locations?

Thanks!

Update:

Let's say we have two globals:

^a(1)="dataa1"
^a(2)="dataa2"

and

^b(1)="datab1"
^b(2)="datab2"

i.e. the structure difference is global name only.

I would like to have two classes TableA and TableB both are inherited from TableAB, and TableAB taking global name as a parameter.

dotnet core

Is there an InterSystems supported dotnet core library or community contributed repo on the horizon? At this time we are exploring installing the ODBC driver in our containers but would rather use more robust solution.

I would like to write some code to parse a set of HTML pages from the internet in order to gather information from each web page.

All of the web pages are generated using a template, so the format of each of the web-pages is consistent with one-another and the information that I want to gather is always located in the same logical place within the page.

What is the best way to parse an html page in order to gather information at a specific place?

Can XML XPATH be used here? Does anyone have any examples of parsing HTML content?

%UnitTest Code Coverage

Hi,

When we write unit test cases for cache object script code using %UnitTest.TestCase, what is the best way to write code to identify code coverage?

So, let say my unit test case hit all 10 lines of code of a method for a given class. So, unit test coverage should be 100% for that. But, using line-by-line coverage [(%Monitor.System.LineByLine] getting wrong percentage, because it also includes code comment/documentation as part of code. So, practically we can not ever achieve 100% of code coverage by using this API.

Hello everyone,

I have a doubt, its possible to use interface like C# using COS?

Remember, interface is different from Abstract Class, because a abstract class can implement code in the method, so I don't want this, I want only define the methods from Class, not allowing implement code.

Hi, Community!

How do you store the source files of your Caché project? What is the directories structure? What are the benefits?

I prefer the following structure:

/cls/package/subpackage/class.cls

/mac/package/routine.mac

/int/package/routine.int

/inc/macro.inc

/dfi/folder/sample.pivot.dfi

Example

Benefits:

  • folders are packages.
  • easy to understand what type of sources are in the project.

What is your approach?
