guess_format_by_header is buggy #143
Description
Hello, Snappy Python can't guess the format for its own compressed output:
import io
import snappy
from snappy import snappy_formats
values = b"What is going on?\n"
def snappy_compress_file_obj(in_file, out_file):
in_file.seek(0)
result = snappy.compress(in_file.read())
out_file.write(result)
out_file.seek(0)
def main():
file_obj = io.BytesIO(values)
output_file_obj = io.BytesIO()
snappy_compress_file_obj(file_obj, output_file_obj)
snappy_formats.guess_format_by_header(fin=output_file_obj)
if __name__ == '__main__':
main()This will throw:
snappy.snappy.UncompressError: Can't detect archive format
