Also, I have limited time, so I want to spend it the better I can, focusing on solving real problems. Setup, Next, Next, Finish, and I want it working without thinking about anything else. It's a philosophy similar to Python: you don't need to know if the platform where it's running is 32 or 64 bits, little or big endian, the operating system, and so on. Just launch it and start typing code: it'll work. It can be also a matter of taste. I like graphical environments since the old Amiga days. If I need a shell, I greatly prefer Python. Anyway, for Windows there's cygwin too, and Python works. But after some months I replaced it with native Windows tools (with VisualStudio on top): I work much, much better this way. If someone is interested in a mingw port, he should consider about having decent alternatives to what a Windows user can found on his platform, otherwise it'll be just pure exercise or a faith matter, since nobody will use it concretely on a daily work. Give users a better choice, and I don't see logical reasons because they'll not change their mind. My 2 cents.

Re: [Python-Dev] mingw support?
The question is who will support those folks? I don't see any reason why you or Martin should support MSYS/mingw if you don't want to, but please don't put down the folks who ask for it. Just say no, it's not worth it. Or maybe, if you want to do the work, I might contribute some reviews. Or whatever. The problem really is that when people ask for MingW support, they mean all kinds of things, and they can't agree among themselves what that is. Some want cross-compiling (i.e. compile using mingw on Linux). Some want autoconf for mingw with msys. Some want autoconf for mingw with cygwin. Some want to replace the build system entirely, and have the new build system support mingw (and claim that you otherwise can't get good mingw support). It's not that I'm objecting mingw support per se, but have my issues with each individual patch proposed so far. As for reviewing: people proposing mingw patches somehow always arrive at very large patches. Reviewing them is very difficult also.

Don’t you have a bootstrapping problem? How do you know where to look at the sysconfig file that tells where to look at config files? Not if located in a place known/owned by the interpreter whatever the layout is. Personally, I'm not clear on what a separate syconfig.cfg file offers over clearly separating the directory configuration settings and continuing to have distributions patch sysconfig.py directly. The bootstrapping problem (which would encourage classifying synconfig.cfg as source code and placing it alongside syscongig.py) is a major part of that point of view. Sure, sysconfig.cfg would be part of the distribution, and this is not really different from code from our core point of view. But it seems more appealing to give the ability to change installation locations through configuration rather than by patching the code, because the latter also implies that Python behaves differently when patched, and add more maintenance burden for everybody. For us for instance, it would be more comfortable to keep most content in sysconfig private, so we can change them at ease without breaking distributions that patches it. I would hate to have to do a deprecation cycle if we change the way sysconfig internally works. A documented cfg file feels just more standard-ish to me for this. Regards.

The first (#3445) is a request from ages ago to make update_wrapper more forgiving when it encounters a missing attribute. Instead of throwing AttributeError (as it does now), it would just skip the missing attribute. This would allow wraps to be used with other callables that don't fully mimic the function API. I was initially opposed to the idea, but over time I've come to think this is a case where practicality beats purity (since that really sums up functools.wraps in general - it is already the case that the copied info isn't quite right for the decorated function, but it's still better than using the wrapper function's own metadata). The second (#9396) came up in the context of the new cache decorators added to functools, and allowing applications to choose their own caching strategies. I suggested exposing the original (uncached) function, and Raymond suggested that the easiest way to enable that would be for functools.update_wrapper to add a new attribute that provides a reference to the original function. Some time back, we considered doing this automatically as an integral part of decoration, but decided that wasn't appropriate. However, building it into the explicit wrapping functions makes sense to me. To avoid namespace conflicts, I plan to use __wraps__ as the name for the reference to the original function. Thoughts? Concerns? Better ideas?

Enthought (32-bit) ships with a mingw gcc compiler configured to build extensions. That might be something to consider for Python on Windows.

But likewise, I think that most Windows users don't care which C compiler was used to build Python. Nor do we/they care which compiler was used to build any other third-party software, as long as the MSI installers works and the binaries are void of malware. Also note that there are non-standard things on Windows that mingw does not support properly, such as COM and structured exceptions. Extensions like pywin32 depend on Microsoft C/C++ for that reason. So for Windows I think it is sufficient to support mingw for extension libraries. The annoying part is the CRT DLL hell, which is the fault of Microsoft. An easy fix would be a Python/mingw bundle, or a correctly configured mingw compiler from python.org. Or Python devs could consider not using Microsoft's CRT at all on Windows, and replacing it with a custom CRT or plain Windows API calls.

Inside of Python you can have a
consistent definition, but that doesn't help people whose installer
gets mixed signals so Python itself is in the wrong place, or who are
using external tools (uninstaller, editor, application, etc) that work
on or with Python.
I'm not arguing for use of AppData, but at least it's easy to explain,
and easy to implement, for consistency.
Likewise with the user directory (IMO) - in fact to explain where
AppData is to a Windows user you first explain about the user directory
(AppData is under the user directory).
Personally I would like to see the defaults being:
Linux: ~/.pythonx.y
Mac OS X: ~/.pythonx.y with a fallback of ~/Library/Preferences/.pythonx.y
Windows: ~/pythonx.y perhaps with a backup of AppData/pythonx.y
For both Windows and Mac OS X I would be happy with the fallback /
primary to be the other way round - it doesn't *really* matter. The API
for getting the user config direction should always return a list I
guess if we have fallbacks.
Someone else in this thread (Adal Chiriliuc) expressed a preferences for
the documents folder on Windows over the home directory. This would be
fine as well (with AppData still as a fallback). This is used by other
native windows applications. (In earlier versions of Windows the
documents folder was explicitly called Documents and Settings.)
We should use pythonx.y rather than just python because (for example)
you will typically have different packages installed when you have
multiple versions of Python, and in unittest would then want / need
different plugins enabled and configured in the unittest config files
for each of the versions of Python.
I've added this text to the issue and Tarek - as bdfl for distutils2
should just make a decision (and the rest of us will have to live with
it). :-)
Another issue is discoverability. Many users won't know about these
config files unless they *see* them.
OK, maybe AppData's out.
In fact for Windows the *correct* thing to do is probably to use
the registry and then provide a graphical tool for editing the
values. If you're arguing for consistency why not argue for this?
Sounds reasonable to me. Except Python's standard GUI is probably not
up to Windows standards of beauty
Heh, I was actually being slightly sarcastic - just pointing out that if
we are going to argue that we should do the correct thing for the
platform that means the registry on Windows and plists on Mac OS X, with
GUI apps to control them. That is an unnecessary burden for the standard
library and actively makes them harder for developers to maintain
themselves.

New Revision: 83992
Log:
Revert regression from r81256 (with release manager approval, see
#8688)
This was a regression in 2.6.6rc1 and I'm grateful to Eric for reverting it.
While I trust he did the merge faithfully, it's still a big enough change
between rc1 and final that I encourage folks who are affected by this to test
current svn head for release26-maint and make sure it's working the way you
expect it to. This means the same as Python 2.6.5. We've decided not to
apply any behavior changing patches to Python 2.6 so you'll just have to live
with the devil you know here, or upgrade to Python 2.7.
Please let me know before Monday if you notice any problems.
Again, thanks Eric!
