[issue1367711] Remove usage of UserDict from os.py
Andrew Dalke added the comment: I was optimization tuning and wondered why UserDict was imported by os. Replacing UserDict with dict passes all existing regression tests. I see the concerns that doing that replacement is not future proof. Strange then that Cookie.py is acceptable. There are three places in Lib which derive from dict, and two are in Cookie.py and in both cases it's broken because set_default does not go through the same checks that __setitem__ goes through. (The other place is an internal class in _strptime.) In looking over existing third-party code, I see this nuance of when to use UserDict vs. dict isn't that well known. The documentation says The need for this class has been largely supplanted by the ability to subclass directly from dict, but that isn't true if anyone is worried about future-proofing and where the subclass changes one of the standard methods. -- nosy: +dalke _ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1367711 _ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue1367711] Remove usage of UserDict from os.py
Andrew Dalke added the comment:
I should have added my preference. I would like to see UserDict replaced with
dict. I didn't like seeing the extra import when I was doing my performance
testing, through truthfully it's not a bit overhead.
As for future-proofing, of course when there's a change in a base class then
there can be problems with derived classes. When that happens, change all of
the affected classes in the code base, and make sure to publish the change so
third parties know about it.
Yes, there's a subtlety here that most people don't know about. But it's not
going to go away.
As for the evil that is 'exec':
exec locals().data['MACHTYPE']=1; print MACHTYPE in {}, os.environ
gives me another way to mess things up.
A point of unit tests is to allow changes like this without worry about code
breakage. And it's not like other non-buggy code wasn't updated over time to
reflect changing style and best practices.
If it's not compatible with Jython or IronPython or PyPy then ignore what I
said, but fix Cookie and update the docs to make that clear as people do think
that it's better to derived from dict for things like this than to derive from
UserDict or UserDictMixin.
I can give a lightning talk about this at PyCon. :)

[issue1339] smtplib starttls() should ehlo() if it needs to
James Henstridge added the comment: From RFC 2487 section 5.2: The client MUST discard any knowledge obtained from the server, such as the list of SMTP service extensions, which was not obtained from the TLS negotiation itself. The client SHOULD send an EHLO command as the first command after a successful TLS negotiation. So the starttls() method should probably also be clearing helo_resp and ehlo_resp (and maybe anything else discovered by ehlo()). There are servers in the wild that will (a) refuse to talk to you unless you issue another EHLO after TLS is negotiated and (b) offer a different set of ESMTP features (such as only supporting SMTP AUTH after TLS).

[issue1813] Codec lookup failing under turkish locale
New submission from Árni Már Jónsson:
When switching to a turkish locale, the codecs registry fails on a codec
lookup which worked before the locale change.
This happens when the codec name contains an uppercase 'I'. What
happens, is just before doing a cache lookup, the string is normalized,
which includes a call to ctype.h's tolower. tolower is locale
dependant, and the turkish locale handles 'I's different from other
locales. Thus, the lookup fails, since the normalization behaves
differently then it did before.
Replacing the tolower() call with this made the lookup work:
int my_tolower(char c)
{
if ('A' = c c = 'Z')
c += 32;
return c;
}
PS: If the turkish locale is not supported, this here will enable it to
an Ubuntu system
a) sudo cp /usr/share/i18n/SUPPORTED /var/lib/locales/supported.d/local
(or just copy the lines with tr in them)
b) sudo dpkg-reconfigure locales

Then there wouldn't be any loss of speed for small integers. For large integers the algorithm I posted should run in time linear in the number of digits of max(a, b), at least in the worst case (though with appropriate optimizations it could be made much faster for 'random' inputs). The current algorithm has essentially O(1) runtime. To get proper timings I'd have to code this up properly.

[issue1798] Add ctypes calling convention that allows safe access of errno
Thomas Heller added the comment: But this thread-local attribute on the function seems bizarre to me. I would prefer another way to get the errno. I can see two alternatives: - the function returns a tuple (normalresult, errno) on each call. - when errno is not zero, EnvironmentError (or WindowsError) is raised. I'd stronly prefer NOT to add errno to the function return value. Raising an Exception when errno or LastError != zero is wrong. There are functions that set the errno or LastError value even if they actually succeed. The recommended way to check for errors that I had in mind is in the 'errcheck' result checker: func = CDLL(..., errno=True) func.argtypes = [...] func.restype = ... def errcheck(result, func, args): if result == -1: # function failed raise EnvironmentError(func.errno) func.errcheck = errcheck Of course, an alternative to a thread local storage attribute would be to pass the error value to the errcheck function. I just felt it would be better not to change the signature, but maybe I was wrong. Anyway, this patch should be extended so that it is also possible to create a foreign function using the descibed calling convention from a prototype created by CFUNCTYPE or WINFUNCTYPE. __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1798 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue1815] Distutils add ability to skip build [Feature Request]
New submission from Daniel Eloff: There seems to be no way to skip the build step when running setup.py install The behavior in such a case should be to skip build and use the existing binaries as created in a separate build step or else print an error. That way you can do setup.py build followed by setup.py install --skip-build and you only have one build taking place. The purpose of this would be to allow build to take place on a separate computer to install. Currently I do this on Vista because MSVC 2003 is not recommended or supported, and distutils won't use the installed MSVC 2005. So I do the build on a (virtual) XP machine and then install by hand for lack of this option.

[issue1215] Python hang when catching a segfault
Ralf Schmitt added the comment: If you replace your call segfault.segfault() with os.kill(os.getpid(), signal.SIGSEGV) everything works as expected. The problem is that the signal is just caught in the c handler (and a flag is set) and then the program continues with the offending *c = 'a'; statement, which again ends with a SIGSEGV and the handler being called. The documentation explicitly states Because the C signal handler always returns, it makes little sense to catch synchronous errors like SIGFPE or SIGSEGV. I think raising that InvalidArgument exception is most probably the right thing to do (or at least printing a warning). Those that really want to handle SIGSEGV should do it from C anyway. -- nosy: +schmir __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1215 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

I've added the following lines to Makefile (in the top level directory).
SELF=$(SELFA)
SELFA=$(SELF)
Running make then hangs.
I'm attaching a patch, which fixes this issue (against trunk). Running
make now prints:
~/python-trunk/ make

[issue1215] Python hang when catching a segfault
Adam Olsen added the comment: The warning in the documentation should be strengthened. Python simply does not and cannot support synchronously-generated signals. It is possible to send a normally synchronous signal asynchronously, such as the os.kill() Ralf mentioned, so it's theoretically possible to use custom handlers for them. However, I can't think of any real use cases, and having such a handler would be asking for trouble if a real synchronously-generated signal was produced. I guess that's an argument for not allowing custom handlers. ;) Suggested documentation: Because of the precarious nature of how synchronously-generated signals must be handled, the signal module does not allow installing handlers for them. This includes SIGSEGV, SIGFPE, SIGBUS, SIGILL, SIGABRT... I haven't been able to find a canonical list if synchronously-generated signals. Furthermore, I've seen conflicting claims about SIGABRT. -- nosy: +Rhamphoryncus __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1215 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue1816] sys.cmd_flags patch
Guido van Rossum added the comment: I like the idea of exposing Python's command line flags, but I think this API is a bit odd. I'd rather see it be a struct with members named after the various arguments and values that are ints or bools -- or simply a bunch of new flags directly in the sys module if making it a string is too much work. It also looks like the patch includes a few unrelated changes to install.py and site.py. -- nosy: +gvanrossum __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1816 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue1817] module-cgi: handling GET and POST together
New submission from Alexandre Fiori: It looks like module-cgi cannot handle GET and POST together when using FieldStorage. For instance, a form action=script.py?key=value action=post is available through cgi.FormContent but not cgi.FieldStorage when there are other input in the html form. Very strange. -- messages: 59848 nosy: alef13 severity: normal status: open title: module-cgi: handling GET and POST together versions: Python 2.5 __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1817 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue1817] module-cgi: handling GET and POST together
Alexandre Fiori added the comment: Here it is, babe. I've made appropriate changes to make it read QUERY_STRING when it's available within POST method. It's currently being parsed by parse_qsl() in read_urlencoded() as it should be in regular GET or POST. I didn't touch CONTENT_LENGTH since it has the size of the POST data without QUERY_STRING's size. That would affect read() of such POST data. It's working. Thanks for the incentive, it's my first patch for python.
