Re: [Python-Dev] Adding the 'path' module (was Re: Some RFE for review)
Martin v. Löwis: This appears to be based on the usedDefault return value of WideCharToMultiByte. I believe this is insufficient: WideCharToMultiByte might convert Unicode characters to codepage characters in a lossy way, without using the default character. For example, it converts U+0308 (combining diaeresis) to U+00A8 (diaeresis) (or something like that, I forgot the exact details). So if you have, say, p-umlaut (i.e. U+0070 U+0308), it converts it to U+0070 U+00A8 (in the local code page). Trying to use this as a filename later fails. There is WC_NO_BEST_FIT_CHARS to defeat that. It says that it will use the default character if the translation can't be round-tripped. Available on WIndows 2000 and XP but not NT4. We could compare the original against the round-tripped as described at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/intl/unicode_2bj9.asp Neil ___ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com

I prepared the patch for 2.4.2 since it is indeed a bugfix. The current test produces wrong results if the compiler is GCC 4.0 which inhibits a successful build of Python 2.4. I tested the patch with GCC 2.95, 3.3 and 4.0 - those are the only compilers I have easy access to right now. I do not see how this patch could cause regressions on other platforms because it mimics the situation w.r.t. ccpython.cc: A C++ translation unit calls from main() an extern C function in a separate C translation unit. The test determines whether it is possible to produce an intact executable if the C compiler is used as linker driver. If this test causes problems on some platform then you'd expect trouble when linking the python executable out of ccpython.o and all the other C object modules anyway. But, of course, I might be wrong. I do not claim that I am familiar with every platform's peculiarities. That's why the patch is up for review. I'd appreciate if users on other platforms test it.

Re: [Python-Dev] [C++-sig] GCC version compatibility
I prepared the patch for 2.4.2 since it is indeed a bugfix. The current test produces wrong results if the compiler is GCC 4.0 which inhibits a successful build of Python 2.4. I should probably add that I'm not flagging that I think there's a problem here. I'm mostly urging caution - I hate having to cut brown-paper-bag releases wink. If possible, can the folks on c++-sig try this patch out and put their results in the patch discussion? If you're keen, you could try jumping onto HP's testdrive systems (http://www.testdrive.hp.com/). From what I recall, they have a bunch of systems with non-gcc C++ compilers, including the DEC^WDigital^Compaq^WHP one on the alphas, and the HP C++ compiler on the HP/UX boxes[1]. (and, it should be added, I very much appreciate the work you've put into fixing this problem) Anthony [1] dunno how useful the HP/UX C++ compiler is going to be - last time I was exposed to it, many years ago, it was... not good. -- Anthony Baxter [EMAIL PROTECTED] It's never too late to have a happy childhood. ___ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com

Available on WIndows 2000 and XP but not NT4. Ah, ok, that's a useful feature. Of course, limited availability of the feature means that we either need to drop support for some systems, or provide yet another layer of fallback routines.
