Resumbmit tar feedback changes, include Android build fix #69469

Submitting the changes approved in this PR: #69107

Addresses: #68230

Include an extra commit addressing the android build failure: The method getgrgid_r is not recognized in Android API level < 24, so the build fails, causing widespread CI failures in PRs and in runtime-extra-platforms. The getgrgid_r method is consumed inside the new Tar APIs to retrieve the group name of the specified group Id. The code checks if getgrgid_r is not available, and then attempt to use getgrgid instead as the fallback, which is not thread-safe, but should be available in older Android API levels.

Include an extra commit addressing the android build failure: The method getgrgid_r is not recognized in Android, so the build fails, causing widespread CI failures in PRs and in runtime-extra-platforms. The getgrgid_r method is consumed inside the new Tar APIs to retrieve the group name of the specified group Id.

An alternative fix would be to check if getgrgid_r is not available, and attempt to use getgrgid instead as the fallback, which is not thread-safe.

The tests that verify group name in the tar archives will fail in android, so I need to address that before merging.

Edit: As of the latest commit, this is no longer valid. The tests should pass in all platforms because those that don't support the _r method should fallback to the non-_r method.

Overall it LGTM, but we also need to disable the Android tests that are using the unavailable API

danmoseley · 2022-05-18T11:22:35Z

Does any mono code use getgrgid on Android ? (It should probably be fixed if it does)

I am 3 distinct tar tests failing in runtime-extra-platforms:

A) net7.0-windows-Release-x64-CoreCLR_release-(Windows.Server.Core.2004.Amd64.Open)[email protected]/dotnet-buildtools/prereqs:windowsservercore-2004-helix-amd64-20200904200251-272704c:

Unrelated to tar. The test successfully copies all the necessary assets, but then fails to establish communication with the docker container after starting it:

All the tests that call the new P/Invoke GetUserName are failing in tvOS and iOS with "No such file or directory" (does not say which errno). I cannot locally build for these platforms, so I'm going to assume we have a similar problem of not having the _r method available on the mobile device, so we need the fallback. I cannot find information that confirms the minimum version where this method is available, but I'll test it with a new commit. Interestingly, I found HAVE_GETPWUID_R checks in mono and coreclr.

@carlossanlop you can surface files to the wasm app by using <WasmFilesToIncludeInFileSystem Include="..." />. And TargetPath attribute to use a custom path for the wasm side.

@eerhardt as discussed offline, I removed any new changes related to Browser from this PR and I will address them separately in #69953

@radical thanks for your suggestion. I'll keep it in mind for the PR I will submit for #69953.

I'm still seeing "Browser" related changes in this PR. Specifically src\System.Formats.Tar.csproj

I see why. It was part of the previously approved PR. Fixed with the last commit.
