Summary: zipfile UnicodeDecodeError
Initial Comment:
I think this is the same as # 705295, which may have
been prematurely closed.
I think the error is dependent on the data or time.
File "C:\Python24\lib\zipfile.py", line 166, in FileHeader
return header + self.filename + self.extra
UnicodeDecodeError: 'ascii' codec can't decode byte
0xd0 in position 10: ordinal not in range(128)
The header is packed like this:
header = struct.pack(structFileHeader,
stringFileHeader,
self.extract_version, self.reserved,
self.flag_bits,
self.compress_type, dostime, dosdate, CRC,
compress_size, file_size,
len(self.filename), len(self.extra))
the header is:
[Dbg]>>> header
'PK\x03\x04\x14\x00\x00\x00\x00\x00\xd0\xa9x2\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00-\x00\x00\x00'
and here are the parts that made it up:
[Dbg]>>> structFileHeader, stringFileHeader,
self.extract_version, self.reserved,
self.flag_bits,self.compress_type, dostime, dosdate,
CRC, compress_size, file_size, len(self.filename),
len(self.extra)
('<4s2B4HlLL2H', 'PK\x03\x04', 20, 0, 0, 0, 43472,
12920, 0, 0, 0, 45, 0)

I'm able to reproduce this bug. Create an arbitrary file named
"Test.bin" having a time stamp of 2005-11-01 16:15:32. Then
run this code:
import zipfile
zipFile = zipfile.ZipFile("Test.zip", "w", zipfile.ZIP_DEFLATED)
zipFile.write(u"Test.bin")
You should see the aforementionned traceback. The problem
occurs when 1. pack() returns a string with some characters >
128 (depends on time stamp); and 2. write() is called with a
unicode parameter (instead of a str parameter).

The "here's the pieces of the" was an accident, you can
ignore it.
My filename was pure ascii, something like
"[EMAIL PROTECTED]"
It seems to me the problem is that the header isn't
decodable. 0xd0 is 208, which is > 128.

The problem is not the data in the file, but the fact that
your filename is probably a Unicode object which fails to
concatenate with the header (which clearly isn't ASCII :-).
I have no idea whether ZIP files support anything other than
ASCII filenames. If you have a reference, please let us know.
If your filename only contains ASCII characters, you should
be able to open the file correctly by first encoding the
filename to ASCII: filename.encode('ascii').
Perhaps zipfile.py should do that for you ?!

Your report ends with 'here's the pieces of the'. Was something
cut off? If you meant to attach a file, try again.
