FAQ 

1. Do libraries have built-in support for popular data storage and processing technologies? 

Yes, Python data orchestration libraries offer built-in support for databases and cloud services. However, the specific level of support and compatibility may vary. It's essential to consult the documentation and resources. Confirm their capabilities and integration options with your chosen technologies. 

 

2. Does some libraries specialize in real-time data orchestration or batch processing? 

Yes, there are specific Python Data Orchestration libraries that specialize in batch processing. Some libraries excel in real-time data processing scenarios. Thus ensuring low-latency and high-throughput data orchestration. Others are optimized for batch processing. They are suitable for tasks like processing large volumes of data at scheduled intervals. The choice of library will depend on your specific data orchestration requirements. They may involve real-time, batch, or a combination of both. Review the features and documentation of these libraries to find the suitable one. 

 

3. What are the monitoring and error-handling best practices in Python Data Orchestration?  

Best practices for monitoring and error handling in Data Orchestration involve: - 

1. Implementing robust logging to record events and errors, 

2. Setting up automated monitoring for real-time performance tracking, 

3. Defining clear error-handling strategies, 

4. Incorporating data validation checks to maintain data quality and 

5. Conducting unit testing to ensure the reliability of your data orchestration workflows. 

These ensure the smooth operation of your data orchestration pipelines. 

  

4. How can I manage and coordinate data pipelines using Python Data Orchestration libraries? 

To effectively manage and coordinate data pipelines using Python Data Orchestration libraries: - 

1. choose the right library, 

2. design your pipeline with clear task dependencies, 

3. implement error handling, 

4. validate data, 

5. monitor and log pipeline performance, 

6. schedule automation, and 

7. maintain comprehensive documentation. 

 

5. Can you guide on handling data dependencies and scheduling in Data Orchestration?  

To handle data dependencies and scheduling, start by defining task dependencies clearly. Specifying which tasks rely on the successful completion of others. Utilize the Python Data Orchestration library to create a dependency graph. This represents the order in which tasks should run, ensuring no circular dependencies. Some libraries also support dynamic dependencies. This allows you to adjust them based on data conditions or runtime values. 

 

For scheduling, leverage the library's scheduling capabilities. It will help you determine when and how often your data pipeline should execute. You can set up schedules using cron-like expressions or specify intervals between runs. Configure concurrency control, especially if tasks share data dependencies, to prevent conflicts.

QUESTION

In JavaScript, can you reference a method/function name within that method/function?

Asked 2022-Mar-28 at 10:35

I am building an automation framework in JavaScript for WebdriverIO.

The "out-of-the-box" error messages aren't too helpful and I would like to add the class name and method name as part of a prefix to the error message which is thrown when the method/function fails.

I have managed to call the class name with ClassName.name

However, I have not found a solution to reference the method name without using some hardcoded value.

Below is a summary of the changes I would like to make.

Before:

1setElementValue(element, value){
2    try{
3        this.waitForElementAndScroll(element);
4        $(element).setValue(value);
5    }
6    catch(error){
7        throw `${BasePage.name}.setElementValue: ${error.message}`;
8    }
9}
10

After:

1setElementValue(element, value){
2    try{
3        this.waitForElementAndScroll(element);
4        $(element).setValue(value);
5    }
6    catch(error){
7        throw `${BasePage.name}.setElementValue: ${error.message}`;
8    }
9}
10setElementValue(element, value){
11    try{
12        this.waitForElementAndScroll(element);
13        $(element).setValue(value);
14    }
15    catch(error){
16        throw `${BasePage.name}.${setElementValue.name}: ${error.message}`;
17    }
18}
19

Where ${setElementValue.name} is the method of referencing the name of the method/function.

Many thanks in advance!

I have tried the following with no success:

method.name //ReferenceError: method is not defined

(method).name //ReferenceError: method is not defined

Function.name //Returns "Function"

Function.value //Returns "undefined"

constructor.name //Returns "Object"

16        throw `${BasePage.name}.${setElementValue.name}: ${error.message}`;
17    }

19this.setElementValue.name
20

where the thrown error message is:

1setElementValue(element, value){
2    try{
3        this.waitForElementAndScroll(element);
4        $(element).setValue(value);

which outputs the following error log when the method fails:

Now i realized that the pdf created with this code behave like when saving to pdf from Excel using the option "Ignore Print areas" (it is one of the options of the export to pdf from Excel feature).

So I decided to "uncheck" that checkbox also from code and I studied the parameters of ExportAsFixedFormat (reference here).

The fifth parameter is IgnorePrintAreas, so I was assuming that passing False to it, the print areas would have been ignored.

I tried several common sense solution, including:

  • passing only that parameter (passing either True or False )
  • passing all the first 5 parameters (just in case they are mandatory at runtime)

but no result: the pdf created by my application still "ignores the print areas".

Does anyone has a suggestion or has experience on this specific subject to give me a pointer to fix this issue?

Thanks.

UPDATE

Thanks to the useful accepted answer I appended to the code above the solution for reference, notice two things:

  1. the RestoreOriginalPrintArea procedure that contains the workaround
  2. the call to oWB.Close(false) at the end

ANSWER

Answered 2022-Mar-10 at 06:48

Root cause of error:

Excel loses print area settings in non-English version of application when file is opened using automation.

Why this is happening:

When you define print area in a sheet, Excel internally creates a named range. It has two properties defining its name:

  1. Name this property is always of the form WorksheetsName!Print_Area (if the sheet's name contains some special characters it is also enclosed in single quotes).
  2. NameLocal has similar structure, but the second part is translated into the language of the application.

This is what it looks like when you open the file in Excel and inspect these properties in VBA, but when you open the same file using automation (for example using the code in question), then NameLocal is no longer translated. This bug causes the named range to not be recognized correctly as print area. oSheet.PageSetup.PrintArea returns an empty string.

Workaround:

Restore original print area after opening the file using:

oSheet.PageSetup.PrintArea:='Print_Area';

This line of code will throw an exception when there was no print area defined in sheet, so there are two options:

  1. Place the line inside try..except block.
  2. Iterate the Names collection and look for a Name ending with !Print_Area, for example:
1function TExportTool.ExportExcelToPDF(aFileName, aNewFileName: String): Boolean;

93    Break;
94  end;
95end;
96

Other important change:

Because the file could have been modified you also need to add:

oWB.Close(false); //do not save changes

before closing the application, otherwise each call to this function would result in another Excel process still running invisible.

Hi, that code works in .ps1, I call the other script, and he makes his job. But when I transform it in .exe with the help of ps2exe, he doesn't do his job anymore. As admin or not. It's not the first time I use that start-process, but it's the first time I use a variable as a target for the command. Do anyone know what go wrong between the ps1 and exe ?

Thanks

While an executable compiled with ps2exe uses a .ps1 file as input, at runtime no actual .ps1 file is involved, which is why PowerShell's command-reflection variables cannot tell you anything about a running script file.

When running an actual .ps1 file, you'd use the following about_Automatic_Variables:

  • $PSCommandPath contains the the executing script file's full file path.

  • $PSScriptRoot contains the script file's full directory path (i.e. the full path of the directory in which the script file is located).

In a ps2exe-compiled executable (.exe), where these variables have no values, you can use the following instead:

  • [Environment]::GetCommandLineArgs()[0] contains the executable file's full file path.

  • Split-Path -LiteralPath ([Environment]::GetCommandLineArgs()[0]) contains the executable file's full directory path.


Applied to your code - assuming that a separate StartApp.ps1 file is present alongside your .exe file:[1]

1$password = ConvertTo-SecureString “Password+++” -AsPlainText -Force
2$Cred = New-Object System.Management.Automation.PSCredential ("Admin", $password)
3$FileLocale = Split-Path -Parent -Path $MyInvocation.MyCommand.Definition
4Write-Output $FileLocale
5$AntFile = "$FileLocale\StartApps.ps1"
6Write-Output $AntFile
7Start-Process PowerShell.exe -ArgumentList "-command &$AntFile -UserCredential $Cred"  
8$FileLocale = Split-Path -LiteralPath ([Environment]::GetCommandLineArgs()[0])
9$AntFile = Join-Path $FileLocale StartApps.ps1
10

If you want to make your code work in both invocation scenarios - the original .ps1 file directly as well as the compiled .exe file - use the following:

1$password = ConvertTo-SecureString “Password+++” -AsPlainText -Force
2$Cred = New-Object System.Management.Automation.PSCredential ("Admin", $password)
3$FileLocale = Split-Path -Parent -Path $MyInvocation.MyCommand.Definition
4Write-Output $FileLocale
5$AntFile = "$FileLocale\StartApps.ps1"
6Write-Output $AntFile
7Start-Process PowerShell.exe -ArgumentList "-command &$AntFile -UserCredential $Cred"  
8$FileLocale = Split-Path -LiteralPath ([Environment]::GetCommandLineArgs()[0])
9$AntFile = Join-Path $FileLocale StartApps.ps1
10$FileLocale = 
11  if ($PSScriptRoot) { $PSScriptRoot }
12  else { Split-Path -LiteralPath ([Environment]::GetCommandLineArgs()[0]) }
13
14$AntFile = Join-Path $FileLocale StartApps.ps1
15

[1] Note that at runtime no information is available about where the original .ps1 file that served as compile-time input was originally located - only that file's content becomes part of the .exe file.

QUESTION

Optionally static class method for interface compatibility

Asked 2022-Jan-24 at 04:33

I've defined a custom ValidateSet parameter attribute like so:

1Class MyValidValuesAttribute : System.Management.Automation.IValidateSetValuesGenerator {
2    [string[]] GetValidValues() { return [string[]]'MyValidValueA','MyValidValueB' }
3}
4

I'd like to avoid having to instantiate the class just to return the set of valid values.

I'd simply call [MyValidValuesAttribute]::GetValidValues() instead of the two-line

1Class MyValidValuesAttribute : System.Management.Automation.IValidateSetValuesGenerator {
2    [string[]] GetValidValues() { return [string[]]'MyValidValueA','MyValidValueB' }
3}
4$X = [MyValidValuesAttribute]::new()
5$Y = $X.GetValidValues()
6

but that method must not be static or the class will not implement the interface.

Is there any way to make a method work the same way regardless of whether the class has been instantiated under the same name? I know I could just implement GetValidValues_Static; wondering if a more elegant solution exists.

ANSWER

Answered 2022-Jan-24 at 04:33

As Santiago Squarzon points out, you don't usually need to instantiate an IValidateSetValuesGenerator-implementing class yourself: PowerShell does it for you when you use such a class in a [ValidateSet()] attribute in order to decorate a parameter in a function's or script's parameter-declaration block (param(...)), so as to constrain the arguments passed to that parameter to the set of values returned from the specified class' .GetValidValues() instance method.

Note: The IValidateSetValuesGenerator interface requires PowerShell (Core) v6+; for solutions that also work in Windows PowerShell, see this blog post that Santiago found.


If you do need to instantiate such a class explicitly:

instead of the two-line

You can use a single(-line) expression:

1Class MyValidValuesAttribute : System.Management.Automation.IValidateSetValuesGenerator {
2    [string[]] GetValidValues() { return [string[]]'MyValidValueA','MyValidValueB' }
3}
4$X = [MyValidValuesAttribute]::new()
5$Y = $X.GetValidValues()
6[MyValidValuesAttribute]::new().GetValidValues()
7

I know I could just implement GetValidValues_Static; wondering if a more elegant solution exists.

If you do need to keep the invocation ceremony to a minimum, you can declare a static property as follows, which then allows you to call [MyValidValuesAttribute]::ValidValues:

1Class MyValidValuesAttribute : System.Management.Automation.IValidateSetValuesGenerator {
2    [string[]] GetValidValues() { return [string[]]'MyValidValueA','MyValidValueB' }
3}
4$X = [MyValidValuesAttribute]::new()
5$Y = $X.GetValidValues()
6[MyValidValuesAttribute]::new().GetValidValues()
7Class MyValidValuesAttribute : System.Management.Automation.IValidateSetValuesGenerator {
8  static [string[]] $ValidValues = [MyValidValuesAttribute]::new().GetValidValues()
9  [string[]] GetValidValues() { return [string[]] ('MyValidValueA','MyValidValueB') }
10}
11

Caveat: Since the static ValidValues property is only initialized once, the above assumes that that the set of valid values is static, which may be at odds with the intentionally dynamic nature of the IValidateSetValuesGenerator interface.

  • In fact, the dynamic nature is the reason that the interface defines .GetValidValues() as an instance method - situationally, a different set of valid values may be returned; otherwise, you could simply use the [ValidateSet()] attribute with a static list of values, such as [ValidateSet('MyValidValueA', 'MyValidValueB')]

As of v7.2.1, PowerShell doesn't support property getters that are called on each invocation - see GitHub issue #2219.

Above automation works, but I have a Branch protection rule that requires review from the Code Owners.

Is there a way to include github-actions to the CODEOWNERS file in order to make its approval counted?

ANSWER

Answered 2022-Jan-20 at 09:46

As of right now, a GitHub app cannot be added to CODEOWNERS as quoted here.

Thank you for being here! Currently, GitHub Apps can’t be used in CODEOWNERS – that’s not supported. It’s something the team is considering for the future, and I’ll be sure to add your use case to the internal feature request.

However, what you can do, is to use a GitHub personal access token generated by yourself as explained in the documentation here, then add it as a secret and use it in your workflow. See the GitHub Documentation .

The last step of your action would then reference your self-defined secret. In the below example, I assume it's called MYTOKEN

1    name: Dependabot auto-approve
2    on: pull_request_target
3    
4    permissions:
5      contents: write
6      pull-requests: write
7    
8    jobs:
9      dependabot:
10        runs-on: ubuntu-latest
11        if: ${{ github.actor == 'dependabot[bot]' }}
12        steps:
13
14          - name: Approve a PR
15            run: gh pr review --approve "$PR_URL"
16            env:
17              PR_URL: ${{github.event.pull_request.html_url}}
18              GITHUB_TOKEN: ${{secrets.GITHUB_TOKEN}}
19
20          - name: Enable auto-merge for Dependabot PRs
21            run: gh pr merge --auto --merge "$PR_URL"
22            env:
23              PR_URL: ${{github.event.pull_request.html_url}}
24              # The documentation incorrectly forgets `GITHUB_TOKEN` here.
25              GITHUB_TOKEN: ${{secrets.GITHUB_TOKEN}}
26          - name: Enable auto-merge for Dependabot PRs
27            run: gh pr merge --auto --merge "$PR_URL"
28            env:
29              PR_URL: ${{github.event.pull_request.html_url}}
30              # The documentation incorrectly forgets `GITHUB_TOKEN` here.
31              GITHUB_TOKEN: ${{secrets.MYTOKEN}}

With this approach, a merge would be done as your user, who is - I assume - part of the CODEOWNERS.

Powershell package missing/not working on release

Asked 2022-Jan-14 at 21:41

I have a console application project where i'm using the powershell SDK, it works perfectly fine in debug but on release, everything except powershell works.

The only settings i've found where it works is when releasing the project as framework dependent and portable. Or at least it works on my pc, on other computers it says the dotnet runtime is missing, even when installed via the link provided.

Using self contained, .net6-windows and win-x86 doesn't work. Not quite sure what could be wrong? I've tried cleaning the project, the solution, restarting visual studio and my PC. Everything works as expected in debug but when I publish, powershell just doesn't work.

Line 14 is me calling PowerShell.Create();

ANSWER

Answered 2022-Jan-14 at 20:16

Without showing actual code and giving a more descriptive detailing about what's going on aside from "it doesn't work" it's difficult to say exactly what is occurring here but I'll do my best.

Thankfully, according to Microsoft's documentation you most certainly can run the Powershell SDK in a self-contained .Net application.

A self-contained .NET application can use Microsoft.PowerShell.SDK to run arbitrary PowerShell functionality without depending on any external PowerShell installations or libraries.

This leads me to believe that you may not be having an issue with the SDK itself but rather with the compiler.

Single-File deployments

I noticed in your screenshot that you are attempting to perform a single-file deployment. You could potentially be having a few issues here. One is to ensure that you're not using an incompatible API. If you are calling any of these within your application, that could be a factor:

  • Assembly.CodeBase
  • Assembly.EscapedCodeBase
  • Assembly.GetFile
  • Assembly.GetFiles
  • Assembly.Location
  • AssemblyName.CodeBase
  • AssemblyName.EscapedCodeBase
  • Module.FullyQualifiedName
  • Module.Name

As none of these are compatible with single-file deployments.

Trimming

Another issue you may be experiencing is referred to as trimming. This is where the compiler will 'trim' unused assemblies from the project at compile time and tends to happen on release runs. While I believe this is off by default you can add the following to your .csproj file to ensure that trimming is disabled:

Optimizing

The JIT compiler tends to try to optimize code on release builds. When we run an application in debug mode the application is optimized for debugging the code. It tries to leave everything almost exactly as you wrote it with maybe some minor differences. When an application is run in release mode the actual code that is being run can be drastically different while maintianing the same logic. This is usually to try and make the final assembly as small and fast as possible. You can disable this optimization by the following steps:

  1. Right click on project
  2. Click "properties"
  3. Go to "Build"
  4. Under the section "general" deactivate "Optimize Code"

optimizecode

Other than the above mentioned possible causes I can't think of much more I can offer without seeing code, or error messages, or further details.

QUESTION

Has Variant behavior changed in Delphi 11?

Asked 2022-Jan-11 at 21:34

In Delphi 10.3, I had written some Excel automation code. I used variants. When the routine was finished, I cleared and freeAndNil the Variant...

1  VarClear(arrData);
2  FreeAndNil(arrData);
3

This compiled and ran fine. I have just upgraded to D11, i.e. Alexandria. This code now gives an error. ... Incompatible Type: TObject and Variant.

I rewrote this portion of code to be:

1  VarClear(arrData);
2  FreeAndNil(arrData);
3  VarClear(arrData);
4  arrData.Free;
5

This compiles, and at first glance, seems to run fine. Is this the proper way to clear/dispose of variants in Alexandria?

ANSWER

Answered 2022-Jan-11 at 19:50

Both of these code snippets are wrong. You don't call Free on a variant. You call Free on an object instance. Simply remove that line.

QUESTION

New-CimSession without elevation by providing admin credentials on Windows 10?

Asked 2021-Dec-31 at 13:43

I need to query some WMI values using PowerShell from Windows 10 devices. The script is executed in the context of a non-admin user by some software distribution tooling.

There is a local admin account, and for the current purpose (retrieving information before wiping the system) it wouldn't be a problem to put the password in the script. As automation is a hard requirement, there is no way to deal with UAC windows or the user to enter some credentials.

Is there any way to get

1$sess = New-CimSession -Credential $admincred
2

to work without running into Access is denied, because it isn't run in an elevated context? Can I somehow self-elevate it by just having the admin credentials?

[Edit]

The comments asked to provide more concrete information:

I want to onboard many unmanaged (i.e. no software distribution tool, no domain join) Windows 10 devices to Windows Autopilot.

  • The devices are not at a specific site.

  • The device vendor can't provide the information.

  • The users don't have administrative privileges

  • The users don't know the local admin password (I do)

  • Exposing the local admin password is less of a problem than the missing tech knowledge of the users (the password is considered legacy)

  • The firewall is preventing incoming traffic (no RDP, WinRM)

  • Code (Source):

    $devDetail = (Get-CimInstance -CimSession $session -Namespace root/cimv2/mdm/dmmap -Class MDM_DevDetail_Ext01 -Filter "InstanceID='Ext' AND ParentID='./DevDetail'")

It is too time consuming to get the information using manual remote sessions with a tool like Teamviewer. Getting the users to download a tool from the intranet and running it would be a way to go. So I created a standalone application that builds and runs a customized PowerShell script. What won't work is getting it to run in an elevated session. I always end up with Access denied.

No you cannot. UAC is designed to prevent exactly what you are trying to do. Related Q&A:

There may be many workarounds, but they all will have in common that you have to go to your machines (locally or remotely) at least once, gain administrative privileges and prepare something, e. g.:

  • A scheduled task that runs under your local administrator account or under SYSTEM and triggers the execution of your script
  • Disabling UAC (temporarily) (not recommended either way)
  • Installing any remote management software, services or accounts (with extra run as background job privilege)

QUESTION

Diagnostic setting not included in Azure Portal ARM template export

Asked 2021-Dec-17 at 08:39

I create a Diagnostic Settings for a KeyVault resource in Azure portal. DS properties are Metrics = AllMetrics and Destination is a predefined Log Analytics Workspace. When I do an export (Automation - Export Template) from Portal, nothing from the diagnostic setting is included in the generated ARM json. I've noticed the same behavior when resource is an App Service.

Is this by design? A bug? Any other way to get the ARM json for the diagnostic setting I've defined?

ANSWER

Answered 2021-Dec-17 at 08:39

I tried the same in my environment and seems we cannot export the diagnostics settings for any service like key vault, app service , storage account etc when we try to export the template for automation . But there are some sample Diagnostics settings Templates for few resources provided in Microsoft Documentation.

So , as per your settings it will something like below which I have tested by deploying :

1{
2        "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
3        "contentVersion": "1.0.0.0",
4        "parameters": {
5            "settingName": {
6                "type": "String",
7                "defaultValue": "testdsansuman"
8            },
9            "vaultName": {
10                "type": "String",
11                "defaultValue": "ansumantestkv1234"
12            },
13            "workspaceName": {
14                "type": "String",
15                "defaultValue": "ansumantestlog"    
16            } 
17        },
18        "resources": [
19            {
20              "type": "Microsoft.KeyVault/vaults/providers/diagnosticSettings",
21              "apiVersion": "2017-05-01-preview",
22              "name": "[concat(parameters('vaultName'), '/Microsoft.Insights/', parameters('settingName'))]",
23              "dependsOn": [],
24              "properties": {
25                "workspaceId": "[resourceId('Microsoft.OperationalInsights/workspaces', parameters('WorkspaceName'))]",
26                
27                "metrics": [
28                  {
29                    "category": "AllMetrics",
30                    "enabled": true
31                  }
32                ]
33              }
34            }
35        ]
36    }
37
