ArcGIS Server SOI - HandleRESTRequest Parameter limitations

The SOI Rest request handler method -

public byte[] HandleRESTRequest(string Capabilities, string resourceName, string operationName,
            string operationInput, string outputFormat, string requestProperties, out string responseProperties)

HandleRESTRequest paramater provides following information inside the method

capabilities Map,Query,Data
 resourceName layers/0, 
operationName query, 
operationInput {"returnZ":false,"returnIdsOnly":false,
"where":"","returnDistinctValues":false,"returnM":false,"returnCountOnly":false,"returnExtentsOnly":false,
"returnTrueCurves":false,"returnGeometry":true,
"spatialRel":"esriSpatialRelIntersects","geometryType":"esriGeometryEnvelope"}, outputFormat json, 
requestProperties {"computeETag":true,"ETag":"\"c429a59c\""}, 
responseProperties {"Content-Type":"text/plain"}

But it has no way of telling service name and layer name ...other than using layer index from resourceName if you want to perform layer specific operation in layers.

[Code Snippet] How to a create user in arcgis portal with a custom role?

Create a user or add member in ArcGIS portal with a custom role -

1. Get all custom roles from the portal, I presumed that the portal already has custom roles other than (org_user, org_publisher, org_admin)

from arcgis.gis import *
gis= GIS(portalUrl, userName, password)
allRoles = gis.users.roles.all(max_roles=50)

2. Create a User with Default Role

username="test"
password=''
firstname='test_name'
lastname='test_last'
email='test@test.com'
description = 'Test Account'
role = 'org_publisher'
provider = 'enterprise'
idp_username = 'test'
level = 2
thumbnail = None

newUser = gis.users.create(username, password,firstname,
               lastname, email, description, role, provider, 
               idp_username, level, thumbnail)


3. Update  the defualt role to Custom Role - Assign the role object not role name

#Assigning the first role out of many portal roles, as an example
status = newUser.update_role(role=allRoles[0]) 
print(status)

If role assigned success, the value of status will be True.

Remote debug environment setup for ArcGIS server extensions- SOE and SOI

In order to debug the ArcGIS server extension SOE/SOI from your development machine, you have to follow 3 steps:

           1.       Enable remote debug ( Presumption is your development machine and GIS server are different machines)

           2.       Enable sever extension for debug

           3.       Attach debugger to the process running the service

Download and install the remote debuggin tools from - https://docs.microsoft.com/en-us/visualstudio/debugger/remote-debugging 

      A.  Enable remote debug

1.       Download and configure Remote tools on the development

a.       Find msvsmon.exe in the directory matching your version of Visual Studio. For Visual Studio 2015:

Program Files\Microsoft Visual Studio 14.0\Common7\IDE\Remote Debugger\x64\msvsmon.exe

(x64 can debug both x86 and x64 but x86 can only debugs x86)

2.       On the remote computer,  copy Remote Debugger folder from development machine and put in C:\ drive. Then, run msvsmon.exe

3.       The msvsmon.exe output terminal shows
