[WIP] Evaluate the usage of Microsoft.Extensions.FileSystemGlobbing as the backing implementation for IMSBuildGlob
- [ ] Add Microsoft.Extensions.FileSystemGlobbing package reference to Microsoft.Build project
- [ ] Create FileSystemGlobbingMSBuildGlob class implementing IMSBuildGlob using Microsoft.Extensions.FileSystemGlobbing
- [ ] Add trait/feature flag to choose between original MSBuildGlob and new FileSystemGlobbingMSBuildGlob implementations
- [ ] Update MSBuildGlob.Parse() method to optionally return the new implementation based on feature flag
- [ ] Create test infrastructure to test both implementations with the same test cases
- [ ] Update existing MSBuildGlob tests to run against both implementations
- [ ] Ensure behavioral compatibility between the two implementations
- [ ] Validate that all existing tests pass with both implementations
Fixes #12032.

Hello @@Copilot, I noticed that you’re changing an .swr file or any file under src/Package/MSBuild.VSSetup.. Please make sure to validate this change by an experimental VS insertion. This is accomplished by pushing to an exp/* branch, which requires write permissions to this repo.

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.
[!WARNING]
Firewall rules blocked me from connecting to one or more addresses
I tried to connect to the following addresses, but was blocked by firewall rules:
dnceng.pkgs.visualstudio.com
- Triggering command:
dotnet build src/Build/Microsoft.Build.csproj --no-restore(dns block)If you need me to access, download, or install something from one of these locations, you can either:
- Configure Actions setup steps to set up my environment, which run before the firewall is enabled
- Add the appropriate URLs or hosts to my firewall allow list
@copilot promising start! There are two test failures:
- Microsoft.Build.Engine.UnitTests.Globbing.FileSystemGlobbingCompatibility_Tests.BothImplementationsShouldMatch(globRoot: "/test", fileSpec: "**/*.cs", testPath: "folder/test.cs", expectedMatch: True)
- Microsoft.Build.Engine.UnitTests.Globbing.FileSystemGlobbingCompatibility_Tests.BothImplementationsShouldMatch(globRoot: "/test", fileSpec: "*.cs", testPath: "test.cs", expectedMatch: True)
Analyze where these two specific cases might be failing and propose some ways to address them.
@copilot promising start! There are two test failures:
- Microsoft.Build.Engine.UnitTests.Globbing.FileSystemGlobbingCompatibility_Tests.BothImplementationsShouldMatch(globRoot: "/test", fileSpec...
The test failures were caused by incorrect path handling in FileSystemGlobbingMSBuildGlob.IsMatch(). The Microsoft.Extensions.FileSystemGlobbing.Matcher expects relative paths, but my original logic was too complex and had bugs when converting between absolute and relative paths.
I simplified the logic to:
- For relative input paths: use them as-is for the matcher
- For absolute input paths: make them relative to the glob root before matching
This fix ensures both implementations return identical results for all test cases. Fixed in commit 37c94b6.

The PerfStar run that @JanProvaznik triggered shows no significant changes in evaluation time. This suggests that we wouldn't regress using M.E.FileSystemGlobbing, but we would ideally be able to compare memory usage as well, and also add a couple large-source-code tests for more variety of impact.
