So you're saying the knowledgeable people's attitude is fuck everyone else as lomg as it's not MY problem? And you people complain about Microsoft. Am I one of those people? You don't exactly make it clear. I'm talking about the people who complain about Microsoft making the VC6 compiler no longer legally available and yet are so irresponsible that they use it for the latest release. But yes, there is a lot of well, it works for me going around. If you do that long enough, people stop complaining, so people wrongly assume there's no longer a problem. This is partly why Python has various warts on Windows and why the standard libraries are oddly biased, why configuring Linux almost always ends up involving hand- editing a .conf file, why the leading cross-platform multimedia library SDL still doesn't do hardware graphics acceleration a decade after such hardware became mainstream, and so on.

os.tmpfile() - permission denied (Win XP)
Hi, Here's what's happening: Python 2.5 (r25:51908, Sep 19 2006, 09:52:17) [MSC v.1310 32 bit (Intel)] on win32 Type help, copyright, credits or license for more information. | import os | os.tmpfile() Traceback (most recent call last): File stdin, line 1, in module OSError: [Errno 13] Permission denied but tempfile.mkstemp() works: import tempfile tempfile.mkstemp() (3, 'c:\\docume~1\\sjm\\locals~1\\temp\\tmpnfuk9i') This is Windows XP Pro SP2. The user with the problem is _not_ an administrator. It works OK when logged on as an administrator. I am using the mode which enables having multiple users logged on and switching between them. The problem happens with Pythons back to 2.2. Python 2.1 on Windows doesn't seem to have a tmpfile() function in the os module. On a Windows 2000 SP4 box, with a Power User [part way between administrator and vanilla user] Python 2.3.5 os.tmpfile() works OK. AFAICT Win XP doesn't have this intermediate level of user. Questions: 1. Before I start checking what permissions who has to do what to which, what directory is it likely to be trying to open the temp file in? C:\WINDOWS\TEMP? 2. What is the general advice about whether to use os.tmpfile() or the functions in the tempfile module? I'm presuming that as os.tmpfile() is ultimately calling tmpfile() in the C stdio library, nobody would have gone to the effort of making the tempfile module just to reproduce stdio functionality, but AFAICT there's no guidance in the docs. Maybe I should be talking to the authors of the package that is using os.tmpfile() :-) TIA for any clues, John -- http://mail.python.org/mailman/listinfo/python-list

Actually I am not aware that this ISO standard exists. My feeling about ISO standards in general are such that I would rather have *anything* else than an ISO standard. These feelings are mainly caused by the frustration of trying to decipher standards written in standardese, liberally sprinkled with non standard acronyms... Its very interesting to learn that you can pass a message without doing a call - when I next need to entertain a children's party as a magician I will endeavour to incorporate it into my act. Thanks for the tip. But more seriously, the concept is that you should couple as loosely as possible, to prevent exactly the kind of trouble that this thread talks about. Just as keyword parameters are more robust than positional parameters, the concept of doing something similar to putting a dict on a queue, is vastly more future-proof than hoping that your call will *get through* when tomorrow's compiler buggers around with the calling convention. One tends to forget that calling also builds messages on the stack. When you boil it right down, all you need for a minimalistic interface are four message types: - get something's value - set something to a value - return the requested value - do something This is not the most minimalistic interface, but its a nice compromise. The advantages of such loose coupling are quite obvious when you think about them, as you don't care where the worker sits - on the other side of the world over the internet, or in the same room in another box, or in the same box on another processor, or on the same processor in another process, or in the same process in another thread...

This is a good reason why you shouldn't share pure Python libraries between different versions (which I have just realised that a couple of my projects are still doing, explaining some extended timings I'd been wondering about - great question!) regards Steve -- Steve Holden +44 150 684 7255 +1 800 494 3119 Holden Web LLC/Ltd http://www.holdenweb.com Skype: holdenweb http://del.icio.us/steve.holden Blog of Note: http://holdenweb.blogspot.com See you at PyCon? http://us.pycon.org/TX2007 -- http://mail.python.org/mailman/listinfo/python-list

So you're saying the knowledgeable people's attitude is fuck everyone else as lomg as it's not MY problem? And you people complain about Microsoft. Am I one of those people? You don't exactly make it clear. I'm talking about the people who complain about Microsoft making the VC6 compiler no longer legally available and yet are so irresponsible that they use it for the latest release. I think you'll find those two sets are disjoint. But yes, there is a lot of well, it works for me going around. If you do that long enough, people stop complaining, so people wrongly assume there's no longer a problem. This is partly why Python has various warts on Windows and why the standard libraries are oddly biased, why configuring Linux almost always ends up involving hand- editing a .conf file, why the leading cross-platform multimedia library SDL still doesn't do hardware graphics acceleration a decade after such hardware became mainstream, and so on. However, the difference between the open-source people and Microsoft is the the open-source people aren't being paid by you for the use of their product, so they're not obligated in any way to help you. This argument has become tiresome. The Python community wants Python to be a big fish in the big pond. That's why they make Windows binaries available. ? I would suggest rather that the Python community (by which you apparently mean the developers) hope that the fruits of their labours will be used by as wide a cross-section of computer users as possible. The goals of open source projects are not those of commercial product developers: I and others wouldn't collectively put in thousands of unpaid hours a year to make a commercial product better and protect its intellectual property, for example. After all, they have already given freely and generously, and if they choose not to give more on top of that, it's really up to them. Right. Get people to commit and then abandon them. Nice. Anyone who committed to Python did so without being battered by a multi-million dollar advertising campaign. The Python Software Foundation has only recently dipped its toes in the advocacy waters, with results that are still under evaluation. And the use of the Microsoft free VC6 SDK was never a part of the official means of producing Python or its extensions, it was a community-developed solution to the lack of availability of a free VS-compatible compilation system for extension modules. I agree that there are frustrations involved with maintaining extension modules on the Windows platform without having a copy of Visual Studio (of the correct version) available. One of the reasons Python still uses an outdated version of VS is to avoid forcing people to upgrade. Any such decision will have fallout. An update is in the works for those using more recent releases, but that won't help users who don't have access to Visual Studio. Yes, it's occasionally very frustrating to the rest of us, but that's life. As the Kurds are well aware. I really don't think you help your argument by trying to draw parallels between the problems of compiler non-availability and those of a population subject to random genocide. Try to keep things in perspective, please. The best I feel I can do is raise these things on occasion, on the off-chance that I manage to catch the attention of someone who is altruistic, knowledgeable, and who has some spare time on their hands! Someone who, say, solved the memory leak in the GMPY divm() function even though he had no way of compiling the source code? Just think of what such an altruistic, knowedgeable person could do if he could use the current VC compiler or some other legally available compiler. Your efforts would probably be far better spent trying to build a back-end for mingw or some similar system into Python's development system, to allow Python for Windows to be built on a regular rather than a one-off basis using a completely open source tool chain. The fact that the current maintainers of the Windows side of Python choose to use a commercial tool to help them isn't something I am going to try and second-guess. To do so would be to belittle efforts I would have no way of duplicating myself, and I have far too much respect for those efforts to do so.

Initial Comment:
Hi!
We had a dscussion about what happens when one drops a file on a python
sourcecode-file in the python-forum [1]. It turned out, that nothing happens at
all. So someone brought up a solution. It is not really a problem with Python
but it would be nice to add this to the Windows Installer.
The proposed solution was to add the following to the registry (this is the
format of the registry editor):
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\Python.File\shellex\DropHandler]
@={86C86720-42A0-1069-A2E8-08002B30309D}
[HKEY_CLASSES_ROOT\Python.NoConFile\shellex\DropHandler]

[HKEY_CLASSES_ROOT\Python.CompiledFile\shellex\DropHandler]
@={86C86720-42A0-1069-A2E8-08002B30309D}
That should be simple thing to do using the MSI-Installer.

This is because this uses fprintf to put out the number, which, in turn, returns -1. This result is ignored; instead Python expects ferror() to be set. However, ferror doesn't get set. For printing strings, fwrite is used. On both Linux and OSX, fwrite will return 0. On Linux, in addition, ferror gets set; on OSX, it doesn't. Reading C99, I can't figure out which of these systems is behaving correctly in what cases. The definition of ferror is that it returns the error indicator of the stream, and only fseek, fputc (+putc), and fflush are explicitly documented to set the error indicator. However, the error indicator is also documented to be set that it records whether a read/write error has occurred, and write is documented to return a number smaller than the requested only if an error occurred. Likewise, fprintf is document to return an negative value if an output or encoding error occurred. Putting these all together, ISTM that both Linux and OSX implement fprintf incorrectly. To work around, Python could check the result of fprintf and fwrite in all places; this might become a large change. -- Comment By: Skip Montanaro (montanaro) Date: 2007-02-06 19:49 Message: Logged In: YES user_id=44345 Originator: NO I verified this behavior on my Mac with /usr/bin/python, Python 2.5 and Python 2.6a0, both built from SVN.

Summary: [PATCH] Debuggers need a way to change the locals of a frame
Initial Comment:
Debuggers need a way to change the local variables in a given frame...
currently, this works only if this change is done in the topmost frame (and
under certain circumstances), but it should work for any frame.
Initial discussion at:
http://mail.python.org/pipermail/python-dev/2007-February/070884.html
Apparently, the problem is the order in which PyFrame_LocalsToFast /
PyFrame_FastToLocals is called.
The proposed solution to this is having a savelocals() method in the frame
object and have it reflect the changes in its returned dict into its locals. It
will simply enable users to call PyFrame_LocalsToFast externally after a
change, to be sure that it will not be changed (and it must be done before
another call to PyFrame_LocalsToFast -- which I don't see as a large problem,
because it is of restrict use -- mainly for debuggers).
- frameobject.c Patch part 1: -
static PyObject *
PyFrame_SaveLocals(PyFrameObject *f)
{
PyFrame_LocalsToFast(f, 0);
Py_INCREF(Py_None);
return Py_None;
}
static PyMethodDef frame_methodlist[] = {
{savelocals, (PyCFunction)PyFrame_SaveLocals, METH_NOARGS,
After a change in f_locals, this method should be called to save the
changes internally.
},
{NULL} /* Sentinel */
};
-- frameobject.c Patch part 2: ---
Add to PyTypeObject PyFrame_Type:
frame_methodlist,/* tp_methods */
-- end patch -
I'm sorry that this is not in an actual patch format... but as I didn't get it
from the cvs, it is easier for me to explain it (as it is a rather small patch).
Attached is a test-case for this patch.
Thanks,
Fabio

A point of detail probably, but I suppose that instead of introducing a
new method on frame objects, we could allow f_locals to be a writeable
attribute. Setting it to a dictionary would update the value of the local
variables. It's a bit of a hack, but so is the need for an explicit
savelocals() method.
A cleaner solution is to have f_locals return a dict-like object instead
of a real dict when appropriate, but it takes more efforts to implement.

Set Indentation width to 8 (was 4 by default). 3. Click on Apply. 4. Click on Ok (nothing happens). 5. Click on Cancel - IDLE exits. Workaround: Replace the Python25/Lib/idlelib directory with the one that comes with python 2.4.3. -- You can respond by visiting: https://sourceforge.net/tracker/?func=detailatid=105470aid=1657034group_id=5470 ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
