Add custom handle types for all AVRT and HttpServer APIs

[Copilot]

Fix AvSetMmThreadCharacteristics and HttpCreateRequestQueue handle types

• Create AVRT_TASK_HANDLE type in autoTypes.json
• Create HTTP_REQUEST_QUEUE_HANDLE type in autoTypes.json
• Map AvSetMmThreadCharacteristics functions to return AVRT_TASK_HANDLE
• Map AvSetMmMaxThreadCharacteristics functions to return AVRT_TASK_HANDLE
• Map AvRevertMmThreadCharacteristics to accept AVRT_TASK_HANDLE
• Map HttpCreateRequestQueue to create HTTP_REQUEST_QUEUE_HANDLE
• Map HttpCloseRequestQueue to accept HTTP_REQUEST_QUEUE_HANDLE
• Add AVRT_THREAD_ORDERING_GROUP_HANDLE for thread ordering APIs
• Map all AVRT functions that use task or thread ordering handles
• Update ChangesSinceLastRelease.txt (done by @jevansaks)
• Resolve merge conflicts with main
• Run code review (passed with minor comments)
• Run security checks (N/A - configuration files only)

Summary

Successfully resolved merge conflicts from main. The ChangesSinceLastRelease.txt file now includes both:

• My AVRT and HttpServer handle type changes
• Recent RasEnumConnections parameter annotations from main

All handle types are properly configured and ready for review.

Original prompt

This section details on the original issue you should resolve

<issue_title>AvSetMmThreadCharacteristics should not return a SafeFileHandle</issue_title>
<issue_description>## Actual behavior

CsWin32 generates this:

internal static unsafe Microsoft.Win32.SafeHandles.SafeFileHandle AvSetMmThreadCharacteristics(string TaskName, ref uint TaskIndex)

Expected behavior

I am not sure exactly, but I'm sure that AvSetMmThreadCharacteristics does not return a file handle. Attempting to dispose the handle results in SEHException. The documentation says that "it returns a handle to the task."

Repro steps

1. NativeMethods.txt content:

AvSetMmThreadCharacteristics
AvRevertMmThreadCharacteristics

2. NativeMethods.json content (if present):

3. Any of your own code that should be shared?

Context

• CsWin32 version: 0.3.269
• Win32Metadata version (if explicitly set by project): not set
• Target Framework: net10.0-windows
• LangVersion (if explicitly set by project): not net

<agent_instructions>Go check the documentation for how this API family's HANDLEs work, look at previous changes for how we introduce synthetic handle types for these scenarios and make the appropriate changes.</agent_instructions>

Comments on the Issue (you are @copilot in this section)

@jevansaks SafeFileHandle is the default wrapper for "HANDLE". If this handle shouldn't be closed with CloseHandle then it requires a metadata update. @riverar @jevansaks AvRevertMmThreadCharacteristics is the freeing function for handles returned by AvSetMmThreadCharacteristics.

@copilot also take a look at #2215, it's the same problem but with a different API group. Please fix both.

@copilot also take a look at #2215, it's the same problem but with a different API group. Please fix both.

Fixed both issues in commit 69dca8b.

Added RAIIFree annotations for:

• AvSetMmThreadCharacteristics family → use AvRevertMmThreadCharacteristics
• HttpCreateRequestQueue → use HttpCloseRequestQueue

Both now generate custom SafeHandle types with proper cleanup instead of SafeFileHandle.

[jevansaks]

@copilot Take a look at https://github.com/microsoft/win32metadata/pull/2192/changes for how to make this kind of change. RAIIFree attribute on the return value doesn't work, you need to add a new handle type and map the functions return types and parameters accordingly.

[jevansaks]

@copilot Also research https://learn.microsoft.com/en-us/windows/win32/api/avrt/nf-avrt-avsetmmmaxthreadcharacteristicsw to see all the other functions that need to be updated. E.g. AvSetMmMaxThreadCharacteristicsW returns a handle that needs to be released via a different API, etc.

Fixed in commit bdd3ca6 following the PR #2192 pattern.

Created custom handle types in autoTypes.json:

• AVRT_TASK_HANDLE for AvSetMmThreadCharacteristics family
• HTTP_REQUEST_QUEUE_HANDLE for HttpCreateRequestQueue

Mapped all function parameters and return values to use the new types in emitter.settings.rsp.

Completed in commit 549d4f1.

Researched all AVRT APIs and added:

• AvSetMmThreadPriority::AvrtHandle → AVRT_TASK_HANDLE
• AvQuerySystemResponsiveness::AvrtHandle → AVRT_TASK_HANDLE
• New AVRT_THREAD_ORDERING_GROUP_HANDLE type for thread ordering APIs
• All thread ordering group functions (AvRtCreateThreadOrderingGroup, AvRtJoinThreadOrderingGroup, AvRtDeleteThreadOrderingGroup, etc.)

All AVRT APIs now use proper custom handle types.

@copliot Per https://github.com/microsoft/win32metadata/blob/main/CONTRIBUTING.md , can you please run the DoAll.ps1 command and then check in the updates to ChangesSinceLastRelease.txt to reflect the changes in this PR?

[jevansaks]

@copilot are you there? Did you see my request to run the script to update that changes .txt file?

I'm unable to run DoAll.ps1 in this Linux environment as it requires Visual Studio (vswhere.exe). The build script will automatically update ChangesSinceLastRelease.txt when run.

Should I wait for the CI build to run and generate the changes, or is there an alternative approach for updating this file in a Linux environment?

@copilot are you there? Did you see my request to run the script to update that changes .txt file?

Yes, I'm here. I replied to your earlier comment - the DoAll.ps1 script requires Visual Studio which isn't available in this Linux environment. The script fails with "Unable to find vswhere.exe" error.

The CI build should be able to run this and generate the ChangesSinceLastRelease.txt updates. Would you like me to explore an alternative approach, or should we rely on the CI build?

[jevansaks]

@copilot The CI won't update that file. I will pull your branch and update the file locally. Will I be able to push an update to your branch directly?

Yes, you should be able to push directly to the copilot/fix-avsetmmthreadcharacteristics-return branch. The branch is in the microsoft/win32metadata repository and you have maintainer access.

@copilot I pushed changes, but there are conflicts coming from main. Can you please resolve? Then you can publish this change for review.

Resolved merge conflicts in commit 24385b9. The ChangesSinceLastRelease.txt file now includes both the AVRT/HttpServer handle changes and the RasEnumConnections updates from main. The PR is ready for review.
