New submission from Ian Laughlin <ilaugh...@novetta.com>:
Recommend adding example to tarfile documentation to provide example of writing
a tarfile to stdout.
example:
files = [(file_1, filename_1), (file_2, filename_2)]
with tarfile.open(fileobj=sys.stdout.buffer, mode = 'w|gz') as tar:
for file, filename in files:
file_obj = io.BytesIO() #starts a BytesIO object
file_obj.write(file.encode('utf-8')) #writes the file to the BytesIO
object
info = tarfile.TarInfo(filename) #creates the TarInfo
file_obj.seek(0) #goes to the beginning of the BytesIO object else it
won't write
info.size = len(file) #sets the length of the file
tar.addfile(info, fileobj=file_obj) #writes the tar to stdout.
