[issue4742] 3.0 distutils byte-compiling - Syntax error: unknown encoding: cp1252
Tarek Ziadé ziade.ta...@gmail.com added the comment: Here's a status: The problem is located in the codec that decodes the data (called by the compile builtin). It throws an error : *** UnicodeDecodeError: 'charmap' codec can't decode byte 0x9d in position 853: character maps to undefined Which is caught by compile and translated into: SyntaxError: unknown encoding: cp1252 So I see two problems: 1/ why compile throws such an error when there's an UnicodeDecodeError 2/ why compile works well under Py2 since 0x9d is not part of the cp1252 mapping I have written a test that reproduces the problem, and I am still investigating. If I can't find the problem I will ask for help on python-dev because I have no knowledge in the compiler internals yet. ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4742 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue4742] 3.0 distutils byte-compiling - Syntax error: unknown encoding: cp1252
John Machin sjmac...@users.sourceforge.net added the comment:
TWO POINTS:
(1) I am not very concerned about chars like \x9d which are not valid in
the declared encoding; I am more concerned with chars like \x93 and \x94
which *ARE* valid in the declared encoding. Please ensure that these
cases are included in tests.
(2) Please check your test data and test results. I get different
results. I have created a file x9d.py by making the minimal changes to
x94.py. For me, this blows up on bytecompiling with *both* 3.0
(UnicodeDecodeError, as expected) and 2.x (Syntax Error unknown encoding
cp1252, wrong message) -- see below.

Added file: http://bugs.python.org/file12492/x9d.py
FWIW, I've tried that file with Python 2.5 and 2.6 on my machine:
lemburg/tmp python2.5 ~/bin/pycompile.py x9d.py
compiling x9d.py - x9d.pyc
XXX type 'exceptions.SyntaxError': unknown encoding: cp1252 (x9d.py, line
0)
lemburg/tmp python2.6 ~/bin/pycompile.py x9d.py
compiling x9d.py - x9d.pyc
XXX type 'exceptions.SyntaxError': unknown encoding: cp1252 (x9d.py, line
0)
Note that the line number is wrong in both messages.
It is interesting that simply running the files gives a more correct
error message:
lemburg/tmp python2.5 x9d.py
File x9d.py, line 2
SyntaxError: 'charmap' codec can't decode byte 0x9d in position 0: character
maps to undefined
lemburg/tmp python2.6 x9d.py
File x9d.py, line 2
SyntaxError: 'charmap' codec can't decode byte 0x9d in position 0: character
maps to undefined
The character position is wrong again in both messages.
Needless to say that the encoding cp1252 is *not* unknown. It looks
like compile() causes the decoding error to be overwritten with a
misleading error message.

Amaury Forgeot d'Arc amaur...@gmail.com added the comment:
This is a duplicate of issue4626.
Here, the content is correctly decoded with cp1252, then passed to
compile(); but compile() works on the internal utf-8 representation, and
tries to decode it again with cp1252!
Yes, the error message is overwritten. If I remove the code that sets
the unknown encoding exception, I get:
compile(open(c:/temp/t1252.py, encoding=cp1252).read(),
t1252.py, exec)
SyntaxError: 'charmap' codec can't decode byte 0x9d in position 35:
character maps to undefined
The 0x9d explains easily:
b\x94.decode('cp1252').encode('utf8')
b'\xe2\x80\x9d'

[issue4742] 3.0 distutils byte-compiling - Syntax error: unknown encoding: cp1252
New submission from John Machin sjmac...@users.sourceforge.net: File foo3.py is [cut down (orig 87Kb)] output of 2to3 conversion tool and (coincidentally) is still valid 2.x syntax. There are no syntax errors reported by any of the following: \python26\python -c import foo3 \python26\python foo3.py \python26\python setup.py install \python30\python -c import foo3 \python30\python foo3.py However 3.0 install \python30\python setup.py install produces: [snip] running install_lib copying build\lib\foo3.py - C:\python30\Lib\site-packages byte-compiling C:\python30\Lib\site-packages\foo3.py to foo3.pyc File C:\python30\Lib\site-packages\foo3.py, line 0 ### Note also line 0 above ### SyntaxError: unknown encoding: cp1252 Same happens if alternative name windows-1252 is used instead of cp1252. NOTE: file foo3.py actually does have some non-ASCII characters (\xa0, \x93, \x94), in comments. Another file (bar3.py) from the same package contains \xb7 twice, but doesn't have the unknown encoding problem. There are several other files in the same package that start with # -*- coding: windows-1252 -*- (or cp1252, or even cp1251(!)) but have no non-ASCII characters in them. They don't get this incorrect error message either. -- components: Distutils files: py3encbug.zip messages: 78273 nosy: sjmachin severity: normal status: open title: 3.0 distutils byte-compiling - Syntax error: unknown encoding: cp1252 versions: Python 3.0 Added file: http://bugs.python.org/file12445/py3encbug.zip ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4742 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

John Machin sjmac...@users.sourceforge.net added the comment:
A clue:
print(ascii(b'\xa0\x93\x94\xb7'.decode('cp1252')))
'\xa0\u201c\u201d\xb7'
Could be that it only happens where there's a cp1252 character that's
not in latin1; see files x93.py and x94.py (have problem) and xa0b7.py
(doesn't have problem).
