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
"myemail at test.com.crt"
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.
