After fix:

Yes, a new folder will be created every time, but I will definitely reproduce this

It has been staying in Extracting

The only difference is that I set the compilation environment to net9

It is not a download, but a decompression problem of GAppM-10.28.0

It is not a download, but a decompression problem of GAppM-10.28.0

Sure, but I still don't understand what the root issue is.

When we decompress GAppM-10.28.0, why do the file(s) already exist?

• If this is the first time it is running, then the folder should be empty and there won't be any existing files.
• If this is the second time it is running, it should have detected that the file(s) already exist and it shouldn't be downloading or extracting them again.

Perhaps another way to explore this:

• Does the TestGMapsDownload test fail for you as well without this change?
• If not, why does it succeed but TestGoogleAppMeasurementDownload hangs? They are exactly the same test but with a different .tar.gz file, so what makes GoogleAppMeasurement-10.28.0.tar.gz hang while c0e534927c0c955e-GoogleMaps-1.11.1.tar.gz succeeds?

[maonaoda]

In fact, tar.gz performs two extractions. The first extraction is successful, but during the second extraction, a confirmation about the existence of the file will appear.

[maonaoda]

The first extraction:

psi

	名前	値	種類
◢	psi	FileName = "C:\Program Files\Microsoft Visual Studio\2022\Enterprise\Common7\IDE\Extensions\Xamarin.VisualStudio\7-Zip\7z.exe",Arguments = "e "-oC:\Users\wangyk\AppData\Local\Temp\tmpp0glvd.tmp\unpacked\GAppM-10.28.0" "C:\Users\wangyk\AppData\Local\Temp\tmpp0glvd.tmp\unpacked\GAppM-10.28.0.tgz"", WorkingDirectory = ""	System.Diagnostics.ProcessStartInfo

The next extraction:

psi

	名前	値	種類
◢	psi	FileName = "C:\Program Files\Microsoft Visual Studio\2022\Enterprise\Common7\IDE\Extensions\Xamarin.VisualStudio\7-Zip\7z.exe", Arguments = "x -snl- "-oC:\Users\wangyk\AppData\Local\Temp\tmpp0glvd.tmp\unpacked\GAppM-10.28.0" "C:\Users\wangyk\AppData\Local\Temp\tmpp0glvd.tmp\unpacked\GAppM-10.28.0\GAppM-10.28.0.tar"", WorkingDirectory = ""	System.Diagnostics.ProcessStartInfo

[maonaoda]

Now that we have obtained the execution parameters for the two decompressions, try to execute them in PowerShell

[maonaoda]

When extracting GAppM-10.28.0.tgz and GAppM-10.28.0.tar, it prompts whether to overwrite because they contain files with the same name.

Is this a problem unique to GAppM-10.28.0?
