[issue41672] imaplib: wrong return type documented
New submission from Norbert Cyran :
Documentation on IMAP4 class specifies wrong return type of its commands:
Each command returns a tuple: (type, [data, ...]) where type is
usually 'OK' or 'NO', and data is either the text from the command
response, or mandated results from the command. Each data is either a
string, or a tuple. If a tuple, then the first part is the header of
the response, and the second part contains the data (ie: ‘literal’
value).
That's not valid for Python 3, as IMAP4 commands return bytes-like objects in
data, what's shown in the example before::
>>> from imaplib import IMAP4
>>> with IMAP4("domain.org") as M:
... M.noop()
...
('OK', [b'Nothing Accomplished. d25if65hy903weo.87'])
That of course can cause a lot of trouble due to incompatibility of strings and
bytes. Suggested change is to replace string occurences to bytes-like object. I
don't know what types are returned in case when tuple is returned though.

[issue39832] Modules with decomposable characters in module name not found on macOS
Norbert added the comment: Yes, if the Python runtime caches file names and determines based on the cache whether a file exists, then it needs to normalize both the file names in the cache and the name of the file it’s looking for. As far as I know, both HFS and APFS do this themselves when asked for a file by name, but if you ask for a list of available files, they don’t know what you’re comparing against. I don’t think codecs would be involved here; I’d use unicodedata.normalize with either NFC or NFD – doesn’t matter which one. -- ___ Python tracker <https://bugs.python.org/issue39832> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue39832] Modules with decomposable characters in module name not found on macOS
New submission from Norbert : Modules whose names contain characters that are in precomposed form but can be decomposed in Normalization Form D can’t be found on macOS. To reproduce: 1. Download and unzip the attached file Modules.zip. This produces a directory Modules with four Python source files. 2. In Terminal, go to the directory that contains Modules. 3. Run "python3 -m Modules.Import". Expected behavior: The following lines should be generated: Maerchen Märchen Actual behavior: The first line, “Maerchen” is generated, but then an error occurs: Traceback (most recent call last): File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/runpy.py", line 193, in _run_module_as_main return _run_code(code, main_globals, None, File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/runpy.py", line 86, in _run_code exec(code, run_globals) File "/Users/business/tmp/pyimports/Modules/Import.py", line 5, in from Modules.Märchen import hello2 ModuleNotFoundError: No module named 'Modules.Märchen' Evaluation: In the source file Modules/Import.py, the name of the module “Märchen” is written with the precomposed character U+00E4. The file name Märchen.py uses the decomposed character sequence U+0061 U+0308 instead. Macintosh file names commonly use a variant of Normalization Form D in file names – the old file system HFS enforces this, and while APFS doesn’t, the Finder still generates file names in this form. U+00E4 and U+0061 U+0308 are canonically equivalent, so they should be treated as equal in module loading. Tested configuration: CPython 3.8.2 macOS 10.14.6 -- components: Interpreter Core files: Modules.zip messages: 363224 nosy: Norbert priority: normal severity: normal status: open title: Modules with decomposable characters in module name not found on macOS type: behavior versions: Python 3.8 Added file: https://bugs.python.org/file48944/Modules.zip ___ Python tracker <https://bugs.python.org/issue39832> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
Re: SMTPHandler and Unicode
Well, you could use an approach like the one suggested here: http://plumberjack.blogspot.com/2010/07/using-custom-formatter-to-dea... That's nice, thanks. I'll use something like this. Just a thought : I will use errors=replace in the call to the encode method to be sure that the logger does not raise any exception. -- http://mail.python.org/mailman/listinfo/python-list
SMTPHandler and Unicode
Hello, I want to send error messages with SMTPHandler logging. But SMTPHandler does not seem to be unicode aware. Is there something doable without playing with sys.setdefaultencoding ? import logging,logging.handlers smtpHandler = logging.handlers.SMTPHandler(mailhost=(smtp.example.com,25), fromaddr=t...@example.com, toaddrs=t...@example.com, subject=uerror message) LOG = logging.getLogger() LOG.addHandler(smtpHandler) LOG.error(usans accent) LOG.error(uaccentu\u00E9) gives : UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 117: ordinal not in range(128) Thank you ! -- http://mail.python.org/mailman/listinfo/python-list

Your package has the same unicode problem :

from mailinglogger.MailingLogger import MailingLogger
mailingLogger = MailingLogger(mailhost=('smtp.example.com',
25),fromaddr='t...@example.com',toaddrs=('t...@example.com',))
LOG = logging.getLogger()

Interesting, I don't know what the logging framework's position is on
unicode...
What happens when you try the same logging with just a FileHandler
registered? What encoding does the log file use?
a FileHandler works as expected, the log file being UTF-8 encoded. The
SMTPHandler is the only logger I know with this problem, maybe
connected to SMTPLib implementation ?

Re: SMTPHandler and Unicode
Ouch. Implicit encoding sounds like a bad behaviour. Looking at the FileHandler source ( http://svn.python.org/view/python/trunk/Lib/logging/__init__.py?view=markup ) : the utf-8 encoding is a fallback. But *FileHandler family let you specify the encoding you want, so that's OK I think. But SMTPHandler does not have such a thing it sends its email with : msg = From: %s\r\nTo: %s\r\nSubject: %s\r\nDate: %s\r\n\r\n%s % ( self.fromaddr, ,.join(self.toaddrs), self.getSubject(record), formatdate(), msg) ... smtp.sendmail(from,to,msg) And there is no encoding in all this. It seems pretty dangerous to me (so my first post) because your application will work without any problem with a FileHandler and the day you'll decide to send email in case of serious problem, it will crash with a UnicodeError. I can't see any workaround, except by subclassing SMTPHandler's emit method to be unicode-aware or at least URF-8 aware. -- http://mail.python.org/mailman/listinfo/python-list

EasyInstall under Windows - strange behaviour
Hello all,
i try to install ZSI under python 2.5 and windows 2000.
I Downloaded the egg and tried the following
c:\Python25\Scriptseasy_install.exe c:\download\ZSI-2.0_rc3-py2.5.egg
The result is that pythonwin pops up and shows the file :
c:\Python25\Scripts\easy_install-script.py :
!C:\Python25\Lib\site-packages\pythonwin\Pythonwin.exe
# EASY-INSTALL-ENTRY-SCRIPT:
'setuptools==0.6c3','console_scripts','easy_install'
__requires__ = 'setuptools==0.6c3'
import sys
from pkg_resources import load_entry_point
sys.exit(
load_entry_point('setuptools==0.6c3', 'console_scripts',
'easy_install')()
)
What is going on here ?
I presume that there are some trivial things I don't understand, can
someone provide apointer or hint ?
Thank you for your time !
Norbert

The problem is the encoding of the Text I'm using German, Can you tell me how to encode the textstring that the Windows commandline shows the special letters right?

Re: Threading Problem
Thanks a lot, Steve, for your fast reply. But the behaviour is the same if 'threadfunction' sleeps longer than just 1 second. 'threadfunction' is of course a dummy to show the problem, imagine a longrunning background-task. If you are right, the question remains 'How can I assure that the starting function finishes, while the other thread still runs ?' . As I said, this is the purpose of threading.
