Summary: tarfile stops expanding with long filenames
Initial Comment:
The tarfile module fixes an issue with "Some old tar programs represent a
directory as a regular file with a trailing slash.":
if tarinfo.isreg() and tarinfo.name.endswith("/"):
tarinfo.type = DIRTYPE
*After* that the full filename is composed. The chars >100 are stored in
"prefix":
if tarinfo.type != GNUTYPE_SPARSE:
tarinfo.name normpath(os.path.join(nts(tarinfo.prefix), tarinfo.name))
So guess what happens if you filename has a / at the 100th character. Right,
its considered a directory. Since directories have no data, the next metadata
block is read from your file data which fails in various ways.
Patch attached.
