LibGit2Sharp.Tests.FilterFixture.CanFilterLargeFiles failed

We get always the exception for a blob-file that ... it could not be opened because it is being used by another process. This exception is thrown by the exception handler in filter.cs , Log.Write(LogLevel.Error, "Filter.StreamWriteCallback exception"); It seems that you rely on exclusive file access when using the stream writer (StreamWriteCallback) with the FileShare.None option. But that assumption may not be correct in this case. git_futils_open_ro opens the blob file in question (read mode), and the file is still open while the stream writer in C is starting. We could trace the file handle on Windows. We follow your advice and use the LibGit2TestPath environment variable to be sure that we have complete control over the output test folder, and we observed that Resource Monitor reports the blob file as being locked by the test engine itself. This is our call stack:

Commencez par LibGit2Sharp.Tests.FilterFixture.CanFilterLargeFiles et examinez filter.cs, en particulier Filter.StreamWriteCallback et le chemin git_futils_open_ro décrit dans le rapport. Reproduisez l’échec sous Windows avec LibGit2TestPath défini, puis suivez les handles de fichiers et confirmez que le test se termine sans l’exception de fichier utilisé.
