Build extensions for windows python 2.4 what are the compiler rules?
by Barry Scott 30 Dec '04

30 Dec '04

I see that, as expected, windows python 2.4 was built with MSVC 7.1 rather then msvc 6.0. It seems that I can build extensions with msvc 6.0 that work with the python 2.4 windows binary kit. Is this safe? I recall warning a while ago about mixing msvc 6.0 and msvc 7.1 runtime DLL's. Is this an issue with python 2.4? I'm also surprised that the python 2.4 source kit only mentions MSVC 6.0 and not the compiler that you actually built python 2.4 with. Barry

This patch just breaks C++ compilation in a different way. The correct solution is a patch to distutils of some kind. from distutils/unixccompiler.py:174 if target_lang == "c++" and self.compiler_cxx: linker[0] = self.compiler_cxx[0] self.spawn(linker + ld_args) "linker" is the variable expanded LDSHARED (or whatever comes out of sysconfig.customize_compiler). -bob

Re: [Pythonmac-SIG] The versioning question...

Would it be an idea to submit a PEP for extending the 'import' keyword? I can imagine it to be like: import spam version 1 import foo version 2, 4 import bar version 7, 1, 6 with version numbers consisting of some fixed maximum of parts and the version number parts not given might be wildcards. We could then have a per module version system like: .../ spam/ 1.0.1/ ... [version 1.0.1 stuff in here] 1.5.7/ ... [version 1.5.7 stuff in here] there should be nothing else in the module directory, except for a mechanism to further support versioning. Default behaviour of 'import spam' would be to select the most recent version. We might want to override that by pointing to some other version. This might be achieved using a symbolic link/alias/shortcut to the directory of that version (spam/current -> spam/1.0.1). More like the directory/module method would be to allow for a __version__.py file in 'spam'. Content of this file is to be determined, but I think it should at least something like __current__ or __version__ to act as the pointer to the current version. --eric

Upcoming PyPy sprint
by Armin Rigo 25 Dec '04

25 Dec '04

Hi Python people, The next sprint for PyPy, the Python-in-Python interpreter, will take place in Leysin, in the lower mountains of Switzerland, 22nd - 29th January 2005 (travel days: 22nd and 29-30th) http://codespeak.net/moin/pypy/moin.cgi/LeysinSprint The technical goals will be two-fold: we want to continue the hard work started at the previous Vilnius sprint (a first generated C version of our interpreter); but the upcoming sprint will also be a "learning PyPy" sprint, covering all aspects of PyPy that are easier to start with. Some examples are described below. For more information about PyPy, see http://codespeak.net/pypy/index.cgi?doc . The "learning PyPy" focus comes from the fact that it will be our first sprint as a European Union sponsored group, and not all members of this EU/PyPy project are already familiar with PyPy. This is a good occasion for newcomers that want to look at PyPy more closely too, in a "fun and somewhat mind-altering" sprint event. Note that as part of our funding we want to be able to support some of the travel and lodging costs for a number of outside people as well, but although the corresponding money is in the budgets, not all administrative issues have been solved yet. We don't know yet if we will be able to do so for the January sprint. However, if you would like to come to the sprint but can't afford travel and accomodation costs then please contact us. Even if the administrative issues have not been sorted out, we may be able to help with private money. Just contact us or me personally for this sprint. About Leysin ------------ The place where the sprint will take place is located in the pre-Alps of the french-speaking (west) region of Switzerland. Leysin is a village at an altitude of 1200 to 1400m. It is a skiing station, and also the place where I (Armin) lived for 20 years. There are 2000 people in summer and 10000 in winter :-) but the sprint will be just before the most crowded periods of February. Of course one full day will be dedicated to winter sports! Both the sprint venue and the logding will be in a very spacious pair of chalets built specifically for bed&breakfast: http://www.ermina.ch/. The place has a baseline ADSL Internet connexion (600Kb); we need to arrange between ourselves to bring a wireless hub. You can of course arrange your own lodging anywhere (you cannot be more than a 15 minutes walk away from the sprint venue), but I definitely recommend to lodge there too -- you won't find better sights anywhere else (though you probably won't get much worse ones easily, either :-) Subscription ------------ Please subscribe at http://codespeak.net/moin/pypy/moin.cgi/LeysinSprintAttendants and mention if you would like to participate in the group reservation, and which size of room you would prefer (2 to 6 beds available). If you wish, you can extend your stay for some days after the 29th of January -- please mention it if you want to book with the group (but you cannot arrive there earier than the 22nd: fully booked). If you have any question don't hesitate to contact pypy-sprint(a)codespeak.net or one of us personally. Learning PyPy ------------- Here are some goals that are quite reachable without in-depth prior knowledge of PyPy: * systematic testing: the interpreter and type implementations work generally well, but there are quite some areas that need refactoring and refinement. A good approach is to run as many of CPython's tests as possible and fix stuff accordingly. This is a good way to learn random parts of PyPy until you know them all! * extension modules and extension types: some can be just rewritten as a plain Python equivalent, but others need to be more integrated into PyPy's internals. * the bytecode compiler: we don't have any compiler integrated with PyPy so far, but there exists a complete set of Python code out there (tokenizer, parser, st->ast, ast->bytecode) that could be used. We could also discuss ideas like syntax extensions generating new bytecodes, etc. * tracing and other wrappers: e.g. how to write a fully debugging Object Space that records the history of all changes to objects, etc. * more bits and pieces: small things missing from our interpreter to be fully compliant. Tracing/profiling hooks come to mind; more small things are listed in http://codespeak.net/svn/pypy/trunk/src/pypy/TODO . In addition to the above examples, there are a number of more involved tasks that nevertheless don't require a complete grasp of PyPy -- whose parts are relatively independent from each other. The "hard" work currently going on in PyPy is on the translation part, which is needed to make PyPy run faster and/or in other environments. This work is however mostly independent. For people that prefer to focus on cross-language stuff rather than Python internals we can discuss about tasks like writing the basics of an interpreter for another language -- for example, it would be great to have a decent error-checking Javascript interpreter, but we can discuss any other language, Python-like or not. In parallel, there is always pending work to allow the code generator to target other languages and platforms (currently there is C, Lisp, Pyrex and Java) or generate code differently (Stackless-style, Psyco-style). A bientot, Armin Rigo

24 Dec '04

I'm about to travel to a place where I don't expect to have internet access for over a week, so this is my last message in 2004. I'll have more time next year for Python that I had this year, so I'm looking forward to working again with this great community. I wish everyone happy celebrations of the dark season, and I hope to see many of you at the upcoming PyCon conference. Cheers! -- --Guido van Rossum (home page: http://www.python.org/~guido/)

Website documentation - link to descriptor information
by Nick Coghlan 24 Dec '04

24 Dec '04

I just spent 10 minutes hunting through the Python website for this link: http://www.python.org/doc/newstyle.html I knew it was there somewhere, I just couldn't find the darn thing. It turns out the major mistake I made was to start from "docs.python.org" instead of "www.python.org/doc". Would it be possible for the "New-style classes" link to be added to the sidebar menu for the individual version's documentation pages? Or else given its own link on the Topic Guides page? Cheers, Nick. -- Nick Coghlan | ncoghlan(a)email.com | Brisbane, Australia --------------------------------------------------------------- http://boredomandlaziness.skystorm.net

Patches: 1 for the price of 10.
by Titus Brown 23 Dec '04

23 Dec '04

Hello all, per previous discussion, http://mail.python.org/pipermail/python-dev/2004-October/049495.html I'd like to push a trivial little patch to sgmllib (#1087808) on you gents, in exchange for my reviews & effort etc. on 10 other patches. Without further ado: No-brainers: 1055159 -- a docstring+docs update to CGIHTTPServer describing already- existing behavior. Recommend apply. 1037974 -- fix HTTP digest auth for broken servers, e.g. LiveJournal. Trivial code fix, should break nothing. Recommend apply + backport. 1028908 -- JJ Lee's updates to urllib2. Passes regr tests, by an original author of much of the code (I think). Recommend apply. 901480 -- patch to urllib2.parse_http_list (bug 735248). Works. Updated patch. Recommend apply + backport. 827559 -- SimpleHTTPServer redirects to 'dir/' when asked for 'dir'. This behavior mimics common behavior online and fixes a problem with relative URLs when clicking on files within 'dir'. Recommend apply. 810023 -- fixes off-by-one bug in urllib reporthook. regr tests & all. Good stuff. Recommend apply + backport. 893642 -- adds allow_none option to SimpleXMLRPCServer & associated classes. Doesn't change default behavior. Recommend apply. 755670 -- modify HTMLParser to accept clearly broken HTML. Recommend reject. Slightly more complicated: 1067760 -- float-->long conversion on fileobj.seek calls, rather than float-->int. Permits larger floats (2.0**62) to match large int (2**62) arguments. rhettinger marked as "won't fix" in the original bug report; this seems like a clean solution, tho. Recommend apply. 755660 -- should HTMLParser fail on all bad input, or do best effort? I'd recommend more sweeping changes where must-fail situations are distinguished from fails-by-default situations. Alternatively take a stand and say "nein!" once and for all. (See my comment for more information.) -- For no particularly good reason, all of these were tested against the current CVS HEAD rather than 2.4. All of them should be trivial to backport, although I think only a few are real problems worthy of the effort. -- I'm kind of curious to see how this goes, I must admit ;). Please CC me on replies so I can listen in... One comment to Martin: it clearly isn't worth the effort of reviewing 10 patches to push a patch the size of my sgmllib patch. On the other hand, it's nice to have a guarantee & it's an educational experience, that's for sure. A 5:1 ratio might be more reasonable, since that in practice will mean 1 serious patch, 2 or 3 updates, and 1 drop-dead easy patch. cheers, --titus
