[issue1415] py3k: pythonw.exe fails because std streams a missing

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc added the comment:

I made some checks with the vc2005 (msvcr80) runtime library:
- fd==-2 corresponds to the _NO_CONSOLE_FILENO constant.
A comment in the CRT code says:
/*
 * For stdin, stdout & stderr, we use _NO_CONSOLE_FILENO (a value
 * different from _INVALID_HANDLE_VALUE to distinguish between
 * a failure in opening a file & a program run without a console.
 */

- in this case, stderr is a buffered FILE*, but the flush() method
always fails. This makes not difference for python2.5, because it never
looks at the return value of fprintf (which is not very consistent, BTW).

Since pythonw (2.5) silently discards any output to stderr, we could
achieve the same by opening the nul file...

[Christian Heimes]

Christian Heimes added the comment:

The patch is a good idea. However it doesn't work for VS 2003 and MSVCR71:

import sys
f = open("stderr.txt", "w")
f.write("stdin: %i\n" % sys.stdin.fileno())
f.write("stdout: %i\n" % sys.stdout.fileno())
f.write("stderr: %i\n" % sys.stderr.fileno())

> pythonw.exe pywtest.py
> type stderr.txt
stdin: -1
stdout: -1
stderr: -1

Doh, you're right:

/me needs to get the code of msvcrt7.

We could simply check for (fd<0) instead, but it's better to reserve
this special processing to stdin/stdout/stderr. maybe somewhere in
pythonrun.c. I'll try a patch later tonight.

[issue1422] Writing to an invalid fd doesn't raise an exception

[Guido van Rossum]

Guido van Rossum added the comment:

I don't think this is worth fixing; you'll get an I/O error as soon as
I/O is attempted, which is upon the first read() for input, or upon the
firsh (implicit or explicit) flush() on output.  You can't tell whether
a fd is valid or not without attempting I/O on it, so trying to test on
each write() call would defeat the purpose of buffering. Testing on
open() is insufficient as long as anybody could call os.close() any time.

[issue1430] Installing on Vista asks to close Explorer (and Nokia PC Suite)

[David Barlow]

New submission from David Barlow:

Version 2.5.1.
I'm trying to install Python on 32bit Vista Business. When I run the 
MSI file it proceeds smoothly (well, apart from offering to install 
to "c:\python..." instead of "c:\program files\python..."), and then 
starts the install. It then tells me that I have to close down Explorer 
(i.e. the shell!), and Nokia PC Suite 6.84.10.3. I could cope with the 
latter, but I'm definitely not prepared to exit explorer. This seems a 
bug/oversight in the installer. Is there any wat round it?

This error message is not produced by the Python MSI file, but by
Windows installer itself. It computes the set of files that we are about

It is safe to ignore this warning, and proceed with the installation.

Closing this as a third-party problem.

[issue1423] wave sunau aifc 16bit errors

[jeroen]

jeroen added the comment:

I played using winsound.PlaySound function for the wav. I used VLC and windows 
media player for wav,au and aiff after that

All had the same problem. It was solved for sunau by doubling the nframes 
number written by the close function in the sunau module. I assume something 
similar should be done for the wav and aiff modules.

This is what I changed in sunau I am not sure if adding *self._sampwidth breaks 
something else. It works for me now when I create 16bit stereo files.

def _patchheader(self):
self._file.seek(8)
# jjk added * sampwidth otherwise for 16 bit you get wrong nframes
_write_u32(self._file, self._datawritten*self._sampwidth)
self._datalength = self._datawritten
self._file.seek(0, 2)

Hope this helps.

Or I could use the paranoid approach: create set from sys.modules.keys()

When the check for fd < 0 is removed from fileio_init() there is no way
to tell if fd < 0 means fd closed or invalid fd.

In order to fix the problem with GUI apps on Windows the check for fd <
0 has to be removed (Python 2.x way). Or we use Amaury's way and open
NUL for reading and writing as a substitute for the standard streams.

I still don't understand. Why do you need to treat a closed fd
different from an invalid fd. In both cases you can't use it and you
shouldn't close it.

I'd suggest that, on Windows, sys.std{in,out.err} should be set to
None instead of a file object when their file descriptor is invalid.
That way print and write requests will fail immediately instead of
nondeterministically. With an invalid file that only blows upwhen
trying to flush you may be able to write a small traceback but it will
still blow up if the traceback is big.

Is there a downside to print/write blowing up right away in apps using pythonw?

I don't want to treat the fd differently. I want to return a sensible
error message that is different from "file closed" when the fd is invalid.

But wouldn't that cause a fatal error when sys.stderr is missing and
Python can't write the traceback to a file like object?

*testing*

No, it works:

object  : Exception('msg',)
type: Exception
refcount: 4
address : 0x839d274
lost sys.stderr

I've an alternative solution based on Amaurgy's idea. Python could set
replacements for stdin, stdout and stderr before it sets up the
preliminary stderr:

#ifdef MS_WINDOWS
/* The standard streams of Windows GUI apps aren't connected. */
if (fileno(stdin) < 0) {
if (freopen("NUL", "rb", stdin) == NULL)
Py_FatalError("Py_Initialize: failed to replace stdin");

[issue1415] py3k: pythonw.exe fails because std streams a missing

[Christian Heimes]

Christian Heimes added the comment:

The mail gateway swallows examples:

>>> raise Exception("msg")
>>> del sys.stderr
>>> raise Exception("msg")
object  : Exception('msg',)
type: Exception

[issue1210] imaplib does not run under Python 3

This patch fixes the issue but I am not entirely sure that it is
correct. I quickly looked at IMAP RFC and there does seem to be spec for
CHARSET in which case, that will have to be used instead of ASCII. It
requires more research and imap knowledge which I can't claim.

As for the tests, we need a imap server to connect to. Perhaps, google
wouldn't mind being used for this purpose?

Doesn't sound too important.  Anyway, from which call do you want to
issue different messages?

I'd rather see sys.stdout == None than opening NUL.

[issue1431] pth files not loaded at startup

[Giambattista Bloisi]

New submission from Giambattista Bloisi:

site.py ha two limitations that make difficult to use pth files on my
linux installation (gobolinux):
- it does not process pth files that are located in directories that are
already present in os.path at the time the main method is invoked
- it does not process directory recursively

Please find attached a patch that solves both. Basically known_paths
became a set representing the directories that have been processed.
Duplicates in os.path are avoided by looking directly into it.

[issue1265] pdb bug with "with" statement

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc added the comment:

Corrected by revision 58958.
"with" is innocent. The problem is this function in abc.py which uses a
generator expression:

def __instancecheck__(cls, instance):
"""Override for isinstance(instance, cls)."""
return any(cls.__subclasscheck__(c)
   for c in {instance.__class__, type(instance)})

It is called both by pdb (deep inside 'print') and the debugged code (in
PyObject_MethodCall), and this reveals the bug.

[issue1432] Strange behavior of urlparse.urljoin

[yan]

New submission from yan:

When I use python 2.4/2.5, I found a strange behavior like this:
urlparse.urljoin("http://www.python.org/[EMAIL PROTECTED]","[EMAIL PROTECTED]")
It will return "http://www.python.org/[EMAIL PROTECTED]".  But I think it
should be "http://www.python.org/[EMAIL PROTECTED]", right? And I
test it in python 2.3. The result is what I supposed it to be.

[issue1265] pdb bug with "with" statement

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc added the comment:

__instancecheck__ should be simpler: all classes are new-style, how is
it possible to have different results for
   instance.__class__
and
   type(instance)
?

[issue1265] pdb bug with "with" statement

[Christian Heimes]

Christian Heimes added the comment:

Good work Amaury! :)

I also wonder how type(cls) != cls.__class__ is possible with new style
classes. So far I found only one way and it ain't beautiful:

>>> class Meta(type):
... def __getattribute__(self, key):
... if key == "__class__": return object
... return type.__getattribute__(self, key)
...
>>> class Example(metaclass=Meta): pass
...
>>> Example.__class__

>>> type(Example)

[issue1415] py3k: pythonw.exe fails because std streams a missing

[Christian Heimes]

Christian Heimes added the comment:

Fixed in r58959

I followed your wish and set sys.stdin, stdout and stderr to None
together with __std?__. I also kept the check for fd < 0 in
fileio_init(). A negative fd still raises the correct error with errno 9
(bad file descriptor).

Good work indeed!

Here's another way:

>>> C().__class__

[issue1265] pdb bug with "with" statement

[Guido van Rossum]

Guido van Rossum added the comment:

BTW: if you can show (e.g. with your unittest) that this indeed breaks
in 2.6 and 2.5, please do backport it.

BTW**2: I've noticed that abc.py's __instancecheck__ gets called a lot
at times when I don't expect it.  Can you research this a bit?
