New submission from July Tikhonov:
In documentation of zipfile.ZipFile.write() there is following notice:
"There is no official file name encoding for ZIP files. If you have unicode
file names, you must convert them to byte strings in your desired encoding
before passing them to write()."
I understand it as that 'arcname' argument to write() shouldn't be of type str,
but rather bytes.
But it is str that works, and bytes that does not:
$ ./python
Python 3.5.0a4+ (default:6f6e78931875, May 1 2015, 23:18:40)
[GCC 4.8.4] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import zipfile
>>> zf = zipfile.ZipFile('foo.zip', 'w')
>>> zf.write('python', 'a')
>>> zf.write('python', b'b')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/july/source/python/Lib/zipfile.py", line 1442, in write
zinfo = ZipInfo(arcname, date_time)
File "/home/july/source/python/Lib/zipfile.py", line 322, in __init__
null_byte = filename.find(chr(0))
TypeError: a bytes-like object is required, not 'str'
(ZipInfo ostensibly attempts to find a zero byte in the filename, but searches
instead for a unicode character chr(0). There are several other places in
ZipInfo class that assume filename being str rather than bytes.)
I consider this a documentation issue: the notice is misleading. Although maybe
there is someone who wants to fix the behavior of ZipInfo to allow bytes
filename.
