Can you post request code?

Another approach would be using dynamic dispatch:

Let's say you have this method:

/// @NiceTest1
ClassMethod Test()
{
    Write 1
}

Using Class Generators you generate 2 additional methods:

/// @NiceTest1
ClassMethod OnBeforeTest()
{
    Write "Before NiceTest1"
}

/// @NiceTest1
ClassMethod OnAfterTest()
{
    Write "After NiceTest1"
}

and you add dynamic dispatch method (and dynamic dispatch classmethod) to the class:

/// Is used to implement an unknown method call.  It is also used
/// to resolve an unknown multidimensional property reference (to get the value
/// of a property) because that syntax is identical to a method call.
Method %DispatchMethod(Method As %String, Args...) [ ServerOnly = 1 ]
{
    // Amethod -> method
    set Method = $e(Method, 2, *)
    do $method(, "OnBefore" _ Method, Args...)
    do $method(, Method, Args...)
    do $method(,"OnAfter" _ Method,Args...)
}

So, as a whole it can look like this:

Class Utils.Annotations1 Extends %RegisteredObject
{

Method OnBeforeTest()
{
    Write "Init NiceTest1",!
}

/// @NiceTest1
Method Test()
{
    Write 1,!
}

Method OnAfterTest()
{
    Write "End NiceTest1",!
}

/// Is used to implement an unknown method call. 
Method %DispatchMethod(Method As %String, Args...) [ ServerOnly = 1 ]
{
    set Method = ..getMethodName(Method)
    do $method(, "OnBefore" _ Method, Args...)
    do $method(, Method, Args...)
    do $method(,"OnAfter" _ Method,Args...)
}

/// Is used to implement an unknown class method call
ClassMethod %DispatchClassMethod(Class As %String, Method As %String, Args...) [ ServerOnly = 1 ]
{
    set Method = ..getMethodName(Method)
    do $classmethod(, "OnBefore" _ Method, Args...)
    do $classmethod(, Method, Args...)
    do $classmethod(,"OnAfter" _ Method,Args...)
}

ClassMethod getMethodName(method As %String) As %String
{
    // Amethod -> method
    set method = $e(method, 2, *)
    return method
}

}

Works like this:

USER>do a.ATest()
Init NiceTest1
1
End NiceTest1
 
USER>do a.Test()
1

You can modify method code during compilation (obviously dangerous) using generators. Here's the sample that annotates all methods, containing @ in description:

Class Utils.Annotations
{

/// @NiceTest1
ClassMethod Test()
{
    Write 1
}

ClassMethod OnCompile() As %Status [ CodeMode = objectgenerator ]
{
    #dim sc As %Status = $$$OK
    for i=1:1:%class.Methods.Count() {
        #dim method As %Dictionary.MethodDefinition = %class.Methods.GetAt(i)
        if method.Description [ "@" {
            set sc = ..annotate(method)
            quit:$$$ISERR(sc)
        }
    }
    quit:$$$ISERR(sc) sc
    set sc = %class.%Save()
    quit sc
}

ClassMethod annotate(method As %Dictionary.MethodDefinition) As %Status
{
    #dim sc As %Status = $$$OK
    set code = method.Implementation.Read($$$MaxCacheInt)
    set code = ..cleadOldAnnotation(code)
    set code = ..addNewAnnotation(code, $e(method.Description, 2,*))
    
    do method.Implementation.Clear()
    do method.Implementation.Write(code)
    
    quit sc
}

ClassMethod cleadOldAnnotation(code As %String) As %String
{
    if $find(code, "//init annotation end") {
        set code = $e(code, $find(code, "//init annotation end") + 2, $find(code, "//complete annotation start") - $l("//complete annotation start") - 2)
    }
    return code
}

ClassMethod addNewAnnotation(code As %String, annotation As %String) As %String
{
    #define Tab $c(9)
    set code =  $$$Tab _ "Write ""Init " _ annotation _ """" _ $$$NL _
                $$$Tab _ "//init annotation end" _ $$$NL _
                code _
                $$$Tab _ "//complete annotation start"_ $$$NL _
                $$$Tab _ "Write ""End " _ annotation _ """"
    return code
}

}

Compiles into:

/// @NiceTest1
ClassMethod Test()
{
    Write "Init NiceTest1"
    //init annotation end
    Write 1
    //complete annotation start
    Write "End NiceTest1"
}

%DB_CACHESYS may also be required, because data for this table is stored in CACHESYS database.

Atelier accesses web port, which can be open.

• Are there any hardware differences?
• Are there differences in memory allocation?

Yes, same as with studio, Caché supports Unit Tests. Documentation.

REST DAL

What's a REST DAL?

If you have a web application, you can enforce codepage on a client side, there are several advantages to it:

• Conversions do not add the load to the server
• JS client libraries are well equipped to deal with various OSes/browsers combinations

The best approach would be to move to unicode.
