To calculate the difference in hours (with decimals) between two %TimeStamp values in ObjectScript, you can use the $ZDATETIMEH function to convert the timestamps into $HOROLOG format, and then calculate the difference using appropriate arithmetic. Here is an example approach:

Code Implementation

ClassMethod CalculateHourDifference(startTime As %TimeStamp, endTime As %TimeStamp) As %Float
{
    // Convert start and end times to $HOROLOG format
    Set startTimeH = $ZDATETIMEH(startTime, 3)
    Set endTimeH = $ZDATETIMEH(endTime, 3)
    
    // Calculate the difference in days and seconds
    Set dayDiff = $PIECE(endTimeH, ",", 1) - $PIECE(startTimeH, ",", 1)
    Set timeDiff = $PIECE(endTimeH, ",", 2) - $PIECE(startTimeH, ",", 2)
    
    // Combine the difference into hours
    Set totalHours = dayDiff * 24 + (timeDiff / 3600)
    
    Return totalHours
}

Explanation

1. $ZDATETIMEH(timestamp, precision) converts a %TimeStamp into $HOROLOG format with the precision value 3 for best compatibility [1][2].
2. $HOROLOG format consists of two parts: the number of days since 31 Dec 1840 and the number of seconds since midnight of the current day.
3. By calculating day and second differences separately, you can then convert the total time difference into hours.

Example

Using your provided timestamps:

Set startTime = "2024-07-12 08:30:00"
Set endTime = "2024-07-12 15:15:00"
Write ##class(YourClass).CalculateHourDifference(startTime, endTime)
// Output: 6.75

This approach ensures precision and clarity while working with timestamps in ObjectScript. [1][2]

a) The error might occur due to an operation that has been interrupted by the system, typically caused by a timeout, or a forced user action or process interruption. This happens when the code execution is halted by an external signal like a system-level command. For more complex handling, implement proper timeout handling or consider logging additional details to diagnose such occurrences further [1][2][3].

b) To view the .INT or .MAC code associated with .OBJ, you can utilize debugging commands or tools within the Cache platform. Using the ObjectScript terminal, invoking debugging frameworks like %SYS.Debug could help. However, ensure that debugging permissions are appropriately assigned. Consider methods or tools that provide insights into such .OBJ routines or consult specific debugging best practices documentation applicable to your Cache release version. Without exact tools defined, specific steps can sometimes be ecosystem-managed system [3][4][5].

Further challenges in processing may arise from mismatches of commands - swizzle directions, context pointer handling errors-hands values. Advised debugging tools , e.g invoke"""

There is no direct documentation or feature in InterSystems Package Manager (IPM) that specifically addresses handling System Default Settings for CI/CD pipelines. However, here are potential approaches based on available information:

1. System Default Settings: These settings simplify management of environment-specific configurations, such as file paths, port numbers, etc., and can be exported/imported using methods like %Export and %Import. It is advisable to integrate these methods into your pipeline processes to automate these tasks [1][2].

2. Custom Automation: While not directly tied to IPM, you can use tools or scripts, such as the GetSettingsFromProduction method, to gather and setup System Default Settings efficiently during the deployment process. This method allows filtering specific settings and automating their migration to the system defaults table [3][4].

3. Source Control: System Default Settings can be exported and tracked in version control. Each branch or CI/CD environment can include specific setting files, which can then be applied programmatically during deployment [2].

If Invoke scripts are acceptable for your case or specific automation needs, they could wrap around these export/import or automation methods to ensure smooth integration without extending IPM itself. For completely eliminating custom solutions, consider submitting a feature enhancement request on InterSystems Developer Community.

1. To list a user and their properties, including roles, you can use ObjectScript commands with the Security.Users class in the %SYS namespace. An example of listing the properties of a user is:

NEW $NAMESPACE
SET $NAMESPACE="%SYS"
SET status = ##class(Security.Users).Get("Username", .properties)
IF $$$ISOK(status) {
    ZWRITE properties
}

This retrieves the user's properties into a reference variable and displays them [1][2].

2. To add a user and set their properties, including roles, you can use the Create method of the Security.Users class. For example:

NEW $NAMESPACE
SET $NAMESPACE="%SYS"
SET properties("FullName") = "New User"
SET properties("Password") = "securepassword"
SET properties("UserRoles") = "%Developer,%Operator"
SET status = ##class(Security.Users).Create("NewUser", .properties)
IF $$$ISOK(status) {
    WRITE "User created successfully."
}

This creates a user with specified roles and other details [1][2].

3. To set a user's password, you can use the Modify method to update the relevant property, as in:

NEW $NAMESPACE
SET $NAMESPACE="%SYS"
SET status = ##class(Security.Users).Get("Username", .properties)
IF $$$ISOK(status) {
    SET properties("Password") = "newpassword"
    SET status = ##class(Security.Users).Modify("Username", .properties)
    IF $$$ISOK(status) {
        WRITE "Password updated successfully."
    }
}

This updates the user's password [1][2].

The use of a separate license server in an HA mirroring environment, such as hosting it on the arbiter machine, might alleviate licensing issues during failovers. Below are key considerations regarding licensing and communication between mirrored servers and users:

1. Role of ISCAgent and Arbiter: The ISCAgent on arbiter machines assists the failover process by ensuring communication reliability between mirror members, even during failovers [1][2]. It does not directly manage user sessions but enables seamless failover between mirrored servers.

2. Licensing Impact on User Sessions: The documentation does not explicitly mention whether adding a license server to the arbiter would prevent users from logging back in after failovers. However, setting up proper failover mechanisms and ensuring that the ISCAgent process is correctly configured on all mirror members can help maintain application continuity during failover [1][2][3].

3. Configuring ISCAgent for Communication: The agent can be configured using /etc/iscagent/iscagent.conf to define the server port and interface. Proper configuration of this communication layer can strengthen connections between mirrored members [3].

Without further specific documentation on the license server itself, you might need to test or consult with support to understand potential benefits or issues before adopting such a setup.

CSP pages in InterSystems IRIS do include mechanisms to interact with JavaScript asynchronously using features like "HyperEventHead()" and "HyperEventCall()". These functionalities allow the execution of server methods triggered by client-side JavaScript, making it possible to update the UI without refreshing the page. However, it appears that the dynamic invocation of server-side code is managed through mechanisms such as cspHttpServerMethod, which relies on specific server support rather than JavaScript's native Promise or async/await functionalities [1].

If you need fully asynchronous JavaScript futures support, it might require an alternative to CSP, such as modern JavaScript frameworks (e.g., Vue.js, React) communicating via REST APIs, as suggested in discussions about the evolving practices for frontend-backend integrations with IRIS [2][3].

The "ErrST+6^%ETN" error message you encountered within %ETN suggests that the application encountered an error during the execution of the error trap utility %ETN. The utility is designed to save information about an error, including the execution stack, job state, and variable values, to the application error log. However, since the error occurred within %ETN itself, detailed error logging was not possible in this instance [1][2][3].

To address errors encountered during the use of %ETN:

1. You can view the application error logs using either the Management Portal or the ^%ERN utility to examine other related logs. This may provide additional clues about the failure [1][4].
2. Consider setting up the $ZTRAP variable to handle or analyze the error before invoking %ETN. For instance:

   SET $ZTRAP="^%ETN"
   

   This ensures that any errors occurring are captured and logged by %ETN [1][5].

Lastly, while dealing with unusual date entries (e.g., "01/06/1841"):

• Review and filter error logs using the Management Portal or ^%ERN, specifically searching by date or error substrings [4][6].
• Check if any system or user inputs inadvertently set such dates during logging or processing activities, as they may be erroneous.

  6.Interpreting Application Error Log

To log an exception to the Application Error Log in InterSystems IRIS, you should use the %Exception.AbstractException.Log() method. Typically, this is done within the CATCH block of a TRY-CATCH construct. Here is an example in ObjectScript demonstrating this approach:

TRY {
    // Code that might throw an exception
} 
CATCH ex {
    // Log the caught exception to the Application Error Log
    DO ex.Log()
}

This method ensures that the details of the exception, including its type and properties, are recorded in the namespace-specific Application Error Log [1].

The error "Attempt to access a protected database" occurs due to a lack of necessary access privileges. In the context of mirrored databases like the ROUTER database on your T2 server, this error typically indicates that the user or process trying to access the database does not hold permissions required for operations on that database.

To resolve this:

1. Ensure that the user or process attempting to mount or access the database on T2 has the appropriate privileges assigned to the database resource. For the database, the relevant permissions are controlled by the associated database resource, such as %DB_. Users must have "Read" permissions to access data and "Write" permissions for modifications [1].

2. If the database has no explicitly defined database resource, it defaults to the %DB_%DEFAULT resource. Ensure that the roles or users interacting with the database have the necessary privileges associated with the %DB_%DEFAULT resource [1].

3. You can verify user privileges by using methods such as $SYSTEM.Security.Check(resourceName, privilegeName). For example:

   WRITE $SYSTEM.Security.Check("%DB_ROUTER", "READ")
   

   This will return 1 if the process has Read permissions on the %DB_ROUTER resource or 0 otherwise [1].

In summary, the error is a result of privilege misconfigurations, and you need to audit and adjust user or process privileges for the concerned database or resource.

To address the behavior of the EnsLib.TCP.TextLineOutboundAdapter, where it expects a terminator and times out if none is provided, you have a few options:

1. Explicitly Set a Terminator: You can set the Terminator property of your adapter to a character or sequence of characters that you might expect (though you already attempted $c(10) or $c(13) without success). According to the documentation, this property supports multi-character strings [1].

   Example of code customization:

   Class Custom.TCPAdapter Extends EnsLib.TCP.TextLineOutboundAdapter
   {
       Property Terminators As %String [ InitialExpression = "" ];  // Clear terminators if none should apply
   }
   

2. Custom Adapter or Manual Reading Logic: If the responses truly do not include terminators and cannot be adjusted on the third-party side, you might need to implement your own logic for receiving data. This involves overriding the necessary methods in the adapter to change how responses are interpreted — possibly using a timeout or a custom data parse handler to disconnect terminator reliance.

   Example of using a manual read logic:

   Method ReadWithoutTerminator()
   {
       // Example of binary mode read without terminators
       set device = "|TCP|Host:Port"
       open device:("R")
       use device
       read x:Timeout
       quit x
   }
   

3. Binary Stream Mode: You could configure the adapter to operate in binary mode (/IOT="RAW"). Manually process the data reading and assembly based on expected response patterns or sizes [2][3].

   Example:

   set device="|TCP|7000"
   open device:(host:port:"M")
   use device:(/IOT="RAW")
   read response:Timeout
   

You should consider adapting the built-in EnsLib.TCP.TextLineOutboundAdapter or creating a subclass of it for better control over edge-case behaviors. [4][2][3]

The code you used (set DOB=$zd(paper.PAPERDob,15)) most likely returns a two-digit year by default because $ZDATE defaults to using two-digit years for certain ranges unless a different option is explicitly set. For years like 1995 or 1999, $ZDATE shows the last two digits as 95 or 99. To display the full year, use the YearOpt parameter.

You can modify the code to explicitly specify four-digit years. Use the YearOpt argument in $ZDATE. The following example forces four-digit years:

set DOB=$ZDATE(paper.PAPERDob,15,,,4)

• $ZDATE(hdate,dformat,monthlist,YearOpt) allows you to specify YearOpt, where:
  • 4 ensures the year is displayed as four digits.
• Format code 15 corresponds to DD/MM/YYYY [1].

If your issue persists, ensure your locale settings align correctly with four-digit years expected in the display [1].

Sources:

The issue you're encountering with $ZF(-100) and the error likely stems from the use of the "/SHELL" flag. For $ZF(-100) to execute commands with this flag, it may encounter file access issues or problems with setup for standard input/output redirection. Specifically, the error can occur if:

1. A file specified for input/output redirection cannot be created or opened.
2. The command cannot be started as requested.

Ensure the following:

• Verify that there are no issues with permissions or availability for any file or resource specified with /STDIN, /STDOUT, or /STDERR flags. These flags control input/output redirection [1].
• When invoking the shell with /SHELL, ensure that the OS command's path is accessible, and there are no syntax errors in the options [1][2].
• Avoid mixing syntax such as redirection operators >> with /STDOUT flags as they might create conflicts [3].

You can resolve this error by ensuring:

1. Necessary permissions are granted to create or open files for redirection.
2. The command and its arguments are validated properly without conflicting flags or operators.
3. Avoid redundant configurations like using /STDOUT flags along with output redirection operators in the command.

For example, to execute a common Windows directory listing command with redirection, use:

set status = $ZF(-100, "/SHELL", "dir", "")
w !,"Status: ", status

Ensure you do not accidentally specify both /STDOUT redirection and shell redirection (>> inside the command). Adjust based on the exact use case and configuration [1][3].

It seems that you're encountering an issue with mapping the FHIR response inside FHIRModel.R4.Patient. Based on provided references, here are some relevant approaches to address this:

1. When working with FHIR responses, it's essential to use the appropriate method to map and handle the response. Utilize the HS.FHIR.DTL.vR4.Model.Resource.Bundle.FromJSON method for parsing the JSON stream of your FHIR response. This method converts the JSON stream into a class object that you can navigate programmatically:

   Set BundleObject = ##class(HS.FHIR.DTL.vR4.Model.Resource.Bundle).FromJSON(pHttpResponse.Data, "vR4")
   

   After converting to a Bundle, you can explore its entry elements to locate and manipulate the Patient resource [1].

2. If you're considering transforming FHIR responses into SDA (Summary Document Architecture), you can use HS.FHIR.DTL.Util.API.Transform.FHIRToSDA3 for converting FHIR messages to the SDA structure. However, note that this specific transformation expects certain configurations and may involve handling additional fields that might not directly belong to a FHIR request [2][3].

3. If the Patient resource isn't being fully populated, validate the FHIR payload against the expected schema. Ensure all mandatory fields and structures align with the FHIRModel.R4.Patient class requirements. In certain cases, mapping issues occur due to missing fields or format mismatches.

4. Lastly, the Quick Stream ID might also be relevant for identifying and processing the incoming FHIR response correctly. Ensure you're interacting with the response appropriately:

   Set quickStreamIn = ##class(HS.SDA3.QuickStream).%OpenId(tResponse.QuickStreamId)
   Set responseObject = ##class(%DynamicObject).%FromJSON(quickStreamIn)
   

These approaches can help debug and refine your handling of the FHIR Patient resource. If further clarification on specific methods is needed, let me know! [4][5][1].

When setting up a web application using Delegated Authentication via InterSystems IPM and ZAUTHENTICATE, you need to address the issue of automatically enabling Delegated Authentication because it doesn't appear to work directly through module.xml. Here's how you can resolve this systematically and implement this authentication mechanism:

1. ZAUTHENTICATE Routine Setup:

   • Create a custom ZAUTHENTICATE routine in the %SYS namespace. This serves as the main entry point for implementing your authentication logic. Example:

     ZAUTHENTICATE(ServiceName, Namespace, Username, Password, Credentials, Properties) PUBLIC
     {
         set tRes=$SYSTEM.Status.OK()
         try {
             set Properties("FullName")="OAuth account "_Username
             set Properties("Username")=Username
             set Properties("Roles")=Password
         } catch (ex) {
             set tRes=$SYSTEM.Status.Error($$$AccessDenied)
         }
         quit tRes
     }
     

     The routine verifies the passed credentials and sets user properties like Roles and FullName as required [1][2].

2. Enable Delegated Authentication Globally:

   • Navigate to System Administration > Security > System Security > Authentication/Web Session Options.
   • Select the "Allow Delegated Authentication" checkbox and save the configuration. This step ensures delegated authentication is enabled for the entire instance [1][2].

3. Enable Delegated Authentication for Specific Applications:

   • In your Web Application (module.xml), include the AutheEnabled field to configure delegated authentication:

     <WebApplication
         Name="/${namespaceLower}/api"
         NameSpace="${namespace}"
         DispatchClass="pkg.isc.genai.rest.Handler"
         MatchRoles=":%All"
         AutheEnabled="#{$$$AutheDelegated}"
         Recurse="1"
         CookiePath="/${namespaceLower}/"
     />
     

     This marks the authentication type for the app as "delegated" [1][2].

4. Manually Adjust Authentication Options (as a workaround):

   • If you still find that the Delegated checkbox is not appearing or operating via the SMP, manually ensure that the Web Session Options page has the necessary Delegated option enabled [1].

5. Automate Delegated Authentication through ClassMethod:

   • To automate enabling Delegated Authentication, write an ObjectScript ClassMethod that sets the required configuration programmatically. For example:

     ClassMethod EnableDelegatedAuth(applicationName As %String) As %Status
     {
         set tApp = ##class(Security.Applications).%OpenId(applicationName)
         if tApp '= "" {
             set tApp.Delegated = $$$YES
             quit tApp.%Save()
         }
         quit $SYSTEM.Status.Error($$$GeneralError, "Invalid application name.")
     }
     

     Call this method in your setup process to apply the delegated setting directly [1].

6. Testing and Debugging:

   • Verify if ZAUTHENTICATE is being called during login attempts.
   • Use the audit log for %System/%Login/LoginFailure events to diagnose any authentication issues [1].

By establishing the proper backend with ZAUTHENTICATE and leveraging programmatic controls for system configurations, you can circumvent limitations in module.xml to enable Delegated Authentication seamlessly. [1][2]

To assign temporary variables within a foreach loop in ObjectScript, you may consider alternatives that enhance readability and maintainability:

1. Using Macros for foreach Iteration: You can define and use macros for looping over arrays and performing actions on each element. A macro can abstract the repetitive code required for array traversal. For example:

   ##; Macro definitions
   #define foreach(%key,%arr,%do) set %key="" for  set %key=$o(%arr(%key)) q:%key=""  do %do
   

   Example usage:

   #include ZFOREACHMACRO
   test $$$foreach(key,^rcc,show)
       quit
   show zwrite @$zr,!
       quit
   

   This approach simplifies the loop logic and makes it more modular [1][2].

2. Extended Command: Another option is creating an extended command ZZFOREACH for iteration. This allows deployment across namespaces and provides flexibility such as starting at a specific subscript or reversing the direction. Example command definition:

   ZZFOREACH(%par) public {
       set %par=$lfs(%par,";")
       new %array,%do,%fwd,%key,%val
       set %array=$lg(%par,1),%do=$lg(%par,2),%fwd=$lg(%par,3),%key=$lg(%par,4)
       if '%fwd set %fwd=1
       if %key]"" set %key=$o(@%array@(%key),$s(%fwd<1:-1,1:1))
       for  set %key=$o(@%array@(%key),%fwd,%val) quit:%key=""  do @%do
       quit 1
   }
   

   Example usage:

   DEMO>zzforeach "^rcc;show^dump(%array,%key,%val)"
   ^rcc(1) = 1
   ^rcc(2) = 2
   ^rcc(3) = 3
   ^rcc(4) = 4
   ^rcc(5) = 5
   

   This method condenses the loop logic and embeds control features [1][2].

3. Using the ObjectScript foreach Library: ObjectScript libraries such as the one in Foreach's GitHub repository enable modular iteration. The library supports dynamic arrays, objects, and other constructs. The syntax for using this is as follows:

   USER>set YOUR_VARIABLE = ["sample","data"]
   USER>do ##class(Iteration.Loop).Foreach(YOUR_VARIABLE,"METHODNAME")
   

   Inside the method (METHODNAME), actions for each element can be defined:

   ClassMethod METHODNAME(pMes) As %Status {
       write pMes, !
       return $$$OK
   }
   

   This library provides flexibility for defining custom methods for element handling [3].

These solutions provide alternatives to for-each loops in ObjectScript that improve code readability and may allow variable assignments during iterations, adhering to your goal [1][3][2].

Sources:

To ensure InterSystems IRIS does not care about the case sensitivity of JSON field names when using %JSON.Adaptor, you can utilize the %JSONFIELDNAME parameter. This parameter allows you to define an alias for a property name, mapping it explicitly to the corresponding JSON field name. For example:

Class Sample.Person Extends (%Persistent, %JSON.Adaptor)
{
    Property Name As %String(%JSONFIELDNAME = "name");
    Property Surname As %String(%JSONFIELDNAME = "surname");
}

With this configuration, the fields in JSON { "name": "John", "surname": "Doe" } will correctly map to the properties Name and Surname in the class without any case sensitivity issues [1][2].

Sources:

To differentiate system-defined and user-defined web applications in InterSystems IRIS, one can use the Management Portal or programmatically determine the type of application.

Using the Management Portal:

1. Navigate to System Administration > Security > Applications > Web Applications.
2. In the list that appears, each application's type will be identified in the Type column, with descriptors such as:
   • User application (CSP)
   • System application (CSP,System) [1][2].

Programmatically:

You can use the %System.CSP.GetDefaultApp method to return the default or other associated properties of applications for a specific namespace. Additionally, you might use specific commands to identify built-in applications as most system-defined apps have predefined names like /api/mgmnt, /csp/atelier, and so on [1][2].

Example Code to Create a Web Application in the %SYS Namespace:

zn "%SYS"
set props("Path") = "/opt/my/app/csp"
set props("Description") = "My Cool Application"
do ##class(Security.Applications).Create("/csp/test", .props)

The above code dynamically creates a web application definition and can be enhanced to include checks for identifying system vs. user-defined properties [3].

These methods should help differentiate the types of web applications efficiently based on your specific requirements.

A built-in method to generate HTTP request and response messages from the %request and %response objects is not explicitly available as described in common documentation. However, if your question is about the GET or POST request handling using %Net.HttpRequest class, you can use the test argument of the Send method of %Net.HttpRequest to view the HTTP message formats:

1. test=1: Outputs the HTTP request message without sending it.
2. test=2: Outputs the HTTP response message.
3. test=3: Outputs only the response headers.

For example:

Set objHttpRequest = ##class(%Net.HttpRequest).%New()
Set objHttpRequest.Server = "api.restful-api.dev"
Set objHttpRequest.Port = "443"
Set objHttpRequest.Https = 1
Set objHttpRequest.SSLConfiguration = "pm.community.intersystems.com"
Set pRequest = {
   "name": "Apple MacBook Pro 16",
   "data": {
      "year": 2019,
      "price": 1849.99,
      "CPU model": "Intel Core i9",
      "Hard disk size": "1 TB"
   }
}
Do objHttpRequest.EntityBody.Write(pRequest.%ToJSON())
Set objHttpRequest.ContentType = "application/json"

// Generate the HTTP request format
Do objHttpRequest.Send("POST", "/objects", 1)

// Send request and fetch HTTP response format
If objHttpRequest.Send("POST", "/objects", 2) { 
    Set objHttpResponse = objHttpRequest.HttpResponse 
}

Note: I used a public REST API just for test purpose.

Using test=1, you can view the raw request; test=2 lets you observe the returned response while also executing the request [1].

The ObjectScript commands you are using to open a TCP connection and write to it appear correct based on InterSystems IRIS documentation.

1. Opening a TCP connection: To initiate a TCP connection, the OPEN command syntax is correct. When using OPEN "|TCP|"_PORT:(IP::"PSE"):10, PORT should be in the allowed range, and IP provided should be an IPv4 address (e.g., "10.200.100.50"). The OPEN command reserves and initiates the device for communication, setting $TEST to 1 upon success [1].

2. Writing to the TCP connection: Using the WRITE command with USE to specify the TCP device is correct. Particularly, the control *-3 flushes the output buffer forcing a write operation to the physical device. The control ensures that data moves from the TCP device buffer to the network buffer, and then to the physical device [1][2]. In the case of TCP communication, this approach is standard for ensuring immediate data transmission without buffering [1].

3. Operating System Handling: The TCP device I/O in InterSystems IRIS leverages underlying operating system mechanisms for network communication. ObjectScript commands such as OPEN, USE, WRITE, and CLOSE interact with these mechanisms to establish connections, send or receive data, and close the connections gracefully [1].

Errors you are facing may be related to network configurations, firewalls, or incorrect VPN setups and not necessarily the syntax or execution of ObjectScript commands. The network team may need to investigate connection-specific issues on the firewall or VPN [1].

To set up an automated linting and code style validation for InterSystems ObjectScript code using CodeTidy and GitHub Actions:

1. Install the CodeTidy Package:

   • Ensure that you have ObjectScript Package Manager (ZPM) installed.
   • Use the command:

     zpm "install isc.codetidy"
     

     This will install the CodeTidy package required for linting ObjectScript code [1].

2. Configure GitHub Actions Workflow:

   • Create a GitHub Actions workflow file in your repository. For example, create a file .github/workflows/objectscript-linting.yml.
   • Define your GitHub Action to include steps where CodeTidy is executed during your CI pipeline.
   • Example workflow:

     name: ObjectScript Lint
     
     on:
       push:
         branches:
           - main
       pull_request:
     
     jobs:
       lint:
         runs-on: ubuntu-latest
         steps:
         - name: Checkout code
           uses: actions/checkout@v3
     
         - name: Install dependencies (ZPM if needed)
           run: |
             # Install ObjectScript Package Manager (if not pre-installed)
             zpm "install isc.codetidy"
     
         - name: Run CodeTidy for linting
           run: |
             # Add commands here to invoke CodeTidy linting
             # as per its documentation
     

     Customize this template based on your CodeTidy usage and specific requirements. Integrate any file exclusions or specific rules for your linting process [1][2].

The error message indicates that the connection to the FTP server is failing due to a missing required argument, identified with the error code 501. Here are troubleshooting steps and relevant settings that could help address your issue:

1. Verify FTP Settings: Ensure that the FTP server settings such as server address (FTPServer), port (FTPPort), username, and password are correctly configured. These settings need to be defined within the FTP adapter or session you are interacting with. Use the FTPServerSet() and FTPPortSet() methods for configuring the server and port, respectively [1][2].

2. Configure SSL/TLS Settings: If you're using SSL/TLS, ensure the configuration is correct. The SSLConfigSet() method allows specifying the TLS configuration entry for authentication. Incorrect or missing SSL configuration could cause issues like the one in your error message [1][2].

3. Check Credentials: Use the CredentialsSet() method to specify the production credentials entry authorizing the connection to the FTP server. Ensure the credentials match those of the FTP server [1][2].

4. Invoke Adapter Test: Use the TestConnection() method provided by the FTP Adapter to verify the connection state. This method can help correct connection-related properties if the adapter thinks it is connected but has lost the socket [1].

5. Error Code 501 Analysis: The error code 501 suggests a protocol error, possibly due to missing arguments during connection initialization. Examine any mandatory parameters in your FTP setup that might be omitted [1][2].

6. Debugging and Logging: Follow InterSystems guidelines for debugging FTP connections, possibly using logs or additional parameter tracing frameworks [2].

Example code snippet to configure the FTP settings:

Set sc = ##class(%Net.FtpSession).FTPServerSet("localhost")
Set sc = ##class(%Net.FtpSession).FTPPortSet("21")
Set sc = ##class(%Net.FtpSession).CredentialsSet("username_password")
Set sc = ##class(%Net.FtpSession).SSLConfigSet("SSLConfigName")
If $$$ISERR(sc) { Write "Error configuring FTP settings! ", sc }

Ensure FileZilla and the FTP adapter are configured for correct environment compatibility and log events to identify any specific errors [1][2].

1. A namespace is a logical abstraction that provides access to one or more databases. It acts as a layer that allows you to organize and manage data and code effectively. In contrast, a database is a physical construct, represented as a single IRIS.DATA file on the operating system, storing the actual data and code [1][2].

2. It is not possible to write data directly into a database without specifying a namespace. When working with ObjectScript or SQL, operations are performed within the context of a namespace. Data is automatically written to the underlying database(s) mapped to that namespace [2][3].

3. You can specify which database to write data into by first changing to the correct namespace and ensuring appropriate mappings are in place. In ObjectScript, you can change namespaces using the SET $NAMESPACE command:

   NEW $NAMESPACE
   SET $NAMESPACE="TargetNamespace"
   

4. A database does not necessarily have to belong to a namespace; it can exist independently. However, a namespace provides the mapping to allow logical access to the database contents. A database can be associated with multiple namespaces, allowing the same data to be accessed from different logical contexts [1].

5. A namespace typically has one "routine" database (for code) and one "data" database for global storage. However, complex mappings are possible where multiple databases can handle different data types or functional roles for a single namespace [1].

The error you are encountering, SSL23_GET_SERVER_HELLO:unsupported protocol, often indicates that the SSL/TLS configuration being used is attempting to negotiate an unsupported SSL/TLS version for the connection. This can occur if a server supports a newer protocol like TLS 1.3 and your implementation is limited to older versions like SSL 3.0 or TLS 1.2.

Here are some troubleshooting steps and points of consideration based on the documents:

1. Update SSL/TLS Configuration:

   • Ensure your SSLConfiguration in the %Net.HttpRequest object is correctly configured to use the protocols supported by the server. For example:

     Set request = ##class(%Net.HttpRequest).%New()
     Set request.SSLConfiguration = "groundca"
     Set request.Server = "osrd.atlassian.net"
     Set request.Https = 1
     Set tSc = request.Get("/rest/api/2/issue/<issue-name>")
     

     You may need to verify that the SSL/TLS configuration named groundca supports the correct set of protocols (e.g., TLS 1.2 or TLS 1.3) [1][2].

2. Enable Supported TLS Versions:

   • If the error is due to protocol mismatch, check whether your Caché system supports the required protocols. Older versions of Caché may not support TLS 1.3, as indicated in some discussions around outdated versions [3][4]. If upgrading to a newer version is not currently an option, you could use an external tool like Stunnel in client mode to handle the TLS encryption [3].

3. Verify Server Certificate and SNI:

   • If the server uses Server Name Indication (SNI), your configuration might need to explicitly include the SNI name. Some versions of Caché do not support SNI, and you may need a workaround for older setups [5]. For instance:

     Set request = ##class(%Net.HttpRequest).%New()
     Set request.SSLCheckServerIdentity = 0
     

4. Troubleshoot Using curl:

   • Since Curl successfully connects using TLS 1.3, it confirms that the server and API key are working as expected. Compare Curl's configurations (e.g., certificates, protocols used) with your Caché setup to identify discrepancies [1].

5. Certificate Matching:

   • Ensure the server name matches the values in its SSL certificate. Sometimes mismatches arise from redirects or incorrect configuration, which can result in an SSL handshake failure [1][5].

If these steps do not resolve the issue, further analysis of the environment and possibly server-side requirements may be needed. It's also advisable to consider upgrading Caché or alternative methods to establish newer protocol support. [1][5][3][4]

Here is a programmatic solution to list all defined namespaces and their databases using both ObjectScript and Python:

ObjectScript Code

ClassMethod ListNamespacesAndDatabases()
{
    // List all defined namespaces
    Set namespaces = ##class(%SYS.Namespace).ListAll(.result)
    zwrite result

    // For each namespace, get its associated databases
    For i = 1:1:result.Count() {
        Set nsName = result.GetAt(i)
        Write "Namespace: ", nsName, !
        Set dbs = ##class(%SYS.Namespace).Databases(nsName, .dbInfo)
        zwrite dbInfo
    }
}

This code lists namespaces and retrieves their database configurations using the appropriate methods provided by the %SYS.Namespace class [1][2].

Python Code

To do this in Python, you need to work within the context of an InterSystems IRIS Python environment.

import iris

def list_namespaces_and_databases():
    result = []
    # List all namespaces
    namespaces = iris.cls('%SYS.Namespace').ListAll()
    for ns in namespaces:
        databases = iris.cls('%SYS.Namespace').Databases(ns)
        db_info = {key: value for key, value in databases.items()}
        result.append({'namespace': ns, 'databases': db_info})

    return result

# Usage
namespaces_and_databases = list_namespaces_and_databases()
for item in namespaces_and_databases:
    print(f"Namespace: {item['namespace']}")
    for db, info in item['databases'].items():
        print(f" Database: {db}, Info: {info}")

This Python example uses the iris module to interact with the InterSystems IRIS system. It retrieves both the namespaces and their associated databases using the same functionalities as ObjectScript [1][3].

These code snippets allow you to programmatically list namespaces and their databases from InterSystems IRIS. Let me know if you need further clarification or assistance!

You may encounter the error Failed to save 'Utils.cls': Unable to write file 'isfs://mip:mz/API/Utils.cls?project=MZ' (Unknown (FileSystemError): Unknown Error) when trying to save or compile a class in Visual Studio Code due to several potential reasons.

Here are some troubleshooting steps based on relevant information:

1. Do Not Alter First Line of New Files: If you are creating a new file in the Explorer tree in VS Code and modify or delete the first automatically generated line after naming the file (e.g., foo.cls), it may cause issues saving the file. Always start coding on the second line and retain the first untouched [1].

2. Namespace and Server Connection Issues: Ensure your connection to the server is functional:

   • Check if you have configured the namespace and server connection properly in VS Code.
   • Use PuTTY or the browser-based management portal to verify connectivity to the server and test your file import or routine executions, as they should work without errors if connectivity is valid [1].

3. Correct Permissions: Make sure that the user configured for your VS Code ObjectScript plugin has the necessary privileges to write to the namespace or specific filesystems in InterSystems IRIS.

4. VS Code Plugin Setup: Ensure the required InterSystems ObjectScript extensions, such as the ObjectScript Extension Pack and Server Manager, are installed and properly configured [1].

If this doesn't resolve the problem, it may be useful to look at the server logs or other error details in the Audit Trail (%SYS.Audit) to get more information.
