[issue23421] tarfile module does not correctly choose compression algorithms

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

No need to use libmagic. tarfile.TarFile.gzopen() should fail if the file is not gzipped tar file. There CLI tests in Lib/test/test_tarfile.py. New test should create tar file with file name that ends with the '.gz' extension and check that it can be open and read with gzopen().
