[issue18118] curses utf8 output broken in Python2
helmut added the comment:
> I suppose that screen.addstr(0, 0, u"äöü".encode("utf-8")) works.
It works as in "the output looks as the one expected". Long lines with utf8
characters will make it break again though.
screen.addstr(0, 0, "äöü" * 20) # assuming COLUMNS=80
Will give two rows of characters of which the first row is 40 characters long.

Sounds sensible. Are you aware of a workaround for this issue? I.e. is there
any way to force Python2.7 to use the wide mode for outputting characters?

[issue2947] subprocess (Replacing popen) - add a warning / hint
New submission from Helmut Jarausch <[EMAIL PROTECTED]>:
Background:
I (as many others, too) have used the following code in the past
ARC='MyDumpFile'
tar_inp= os.popen('/bin/tar cjf '+ARC+' -T -','w')
tar_exit_code= tar_inp.close()
if tar_exit_code != None and tar_exit_code % 256 :
print "some error messages"
When replacing this - as suggested - by
TAR= Popen(('/bin/tar','cjf',ARC,'-T','-'),stdin=PIPE)
tar_inp= TAR.stdin
tar_inp.close() always returns None which was an indication
of NO ERROR when used together with popen.
So this has proabaly to be replaced by
tar_inp.close()
tar_exit_code= TAR.wait()
if tar_exit_code != 0 :
print "some error messages"
I suggest a warning / hint to change checking for errors
when upgrading to subprocess.Popen

[issue3131] 2to3 can't find fixes_dir
Helmut Jarausch <[EMAIL PROTECTED]> added the comment:
This patch seems to work, but
when invoked it tries to write to /usr/local/lib/python3.0/lib2to3
( I get
root: Writing failed:[Errno 13] Permission denied: '/usr/local/lib/
python3.0/lib2to3/PatternGrammar3.0.0.beta.1.pickle'
)
I hope this will be handled during install in future.
Furthermore, as a test, I copied refactor.py to xxx.py
and ran 2to3 on xxx.py
Here I get
RefactoringTool: Can't parse xxx.py: ParseError: bad input: type=22,
value='=', context=('', (67, 71))
This error message is a bit terse for someone not knowing the details
of 2to3
Thanks for the patch,
Helmut.

[issue17413] format_exception() breaks on exception tuples from trace function
Helmut Jarausch added the comment: The problem is caused by the new format_exception in Python's traceback.py file. It reads def format_exception(etype, value, tb, limit=None, chain=True): list = [] if chain: values = _iter_chain(value, tb) else: values = [(value, tb)] for value, tb in values: if isinstance(value, str): and then def _iter_chain(exc, custom_tb=None, seen=None): if seen is None: seen = set() seen.add(exc) its = [] context = exc.__context__ As you can see, the new keyword parameter chain is True by default. Thus, iter_chain is called by default. And there you have context= exc.__context__. Now, if value is an object of type str Python tries to access the __context__ field of an object of type str. And this raises an attribute error. In an application (pudb) I've used the fixed exc_info= sys.exc_info() format_exception(*exc_info,chain=not isinstance(exc_info[1],str)) So, why is the keyword parameter 'chain' True by default. This causes the problem. -- nosy: +HJarausch ___ Python tracker <http://bugs.python.org/issue17413> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
