python clone of "otool -Lv"
by Bob Ippolito July 28, 2003

July 28, 2003

I did a quick proof-of-concept utility that clones the functionality of otool -Lv today. It needs ctypes, because that's how I wrote the structure parsing stuff... not for any other good reason. The output of "python potool.py /some/executable_or_dylib" should be identical to the output of "otool -Lv /some/executable_or_dylib". The idea behind this is to write a version of install_name_tool in Python, so that we don't have to depend on the presence of developer tools for that kind of installation. It's pretty essential for bundlebuilder kinda stuff if you want to embed frameworks, or installing frameworks to semi-arbitrary locations on a user's computer (i.e. admin, network or user). It doesn't do this yet, but all the parsing/generating code for this kind of modification is there. There's an ld flag that you should to use to pad these headers (-headerpad_max_install_names) if you're going to have any luck making paths longer. By default, they end up with just enough zero padding cstring termination and 32bit alignment. It's available at: http://undefined.org/python/potool-0.0.tgz Anyone, please feel free to take this and write the install_name_tool code ;) All the information I needed to write this part of the functionality was in /usr/include/mach-o/loader.h. I took a look at the install_name_tool source code and man page. The best it does is modify these dylib structures in-place. It's not capable of expanding them to accommodate paths beyond the padding size of the mach-o file. Emulating this tool should be rather easy. -bob

Python site
by Chris July 28, 2003

I think the snake thing is too intrenched. It has nothing to do with the original Python which as you know refers to Monty Python's Flying Circus. According to The BCC the program was to be called "Flying Circus" (AKA the Red Baron) but it didn't seen to stick. While in production somebody came up with the term " Monty Python's Flying Circus" and the rest is history. As the BBC says: "But as planning for the series became more confused, the BBC management began to refer to the team as a 'flying circus' - inspired by the Red Baron's World War One fighter squadron. With the addition of the random moniker Monty Python, the name gained general approval. " http://news.bbc.co.uk/1/hi/special_report/1999/10/99/monty_python/455585.stm So we have a scripting language called Python and we are stuck with the snake. I kinda wish it had been called "nudge, nudge, wink, wink" or SPAM,SPAM,SPAMMedy,SPAM or the "Dead Parrot". Let me have a look at it. I have 30 years of graphics experience and love to do AQUA in Photoshop! Still need your ideas though... Chris Dwyer

My reason for hoping for a 'better' icon is simply because a number of folks don't like spiders or snakes or anything creepy or crawly. Python is a work of art. The Mac is a work of art. Put the two together and you have a dynamite combination. ...but for the icon. It does turn some folks off. The covers of books are not immune either. I've seen one person not buy Lutz's book after the comment "ugh. ...a snake." Not rational? Definitely, but it goes to first impressions. Yes, there is now some history with the snake. Yes, a lot of people are not bothered, and in fact, a number even seek out the dark and creepy stuff. ...but that is not what Python and the Mac are all about. It is supposed to be pleasant experience. OK, now that I have ranted... what should the icon be? I'll be honest, I don't know. I was hoping those of you that are more creative and have a feel for graphic arts would be able to suggest something. I don't want to be a bad guy, but I get the impression this should be fixed. Thanks for listening, Larry

PIL fails due to missing imaging.so
by Pijus Virketis July 27, 2003

July 27, 2003

Dear all, I have a stock installation of MacPython 2.2.2 on MacOSX 10.2.6. I am trying to use PIL to create a thumbnail: >>> import Image >>> im = Image.open("test.jpg") >>> im.size (300, 300) >>> im.thumbnail((200,200)) [...long error traceback cut...] ImportError: The _imaging C module is not installed I searched my hd, and did not find imaging.so anywhere. Do I have an incomplete PIL installation (needed to select some option during MacPython installation ..?), or is there something more sinister going on? Thank you! Pijus

fpconst vs pickle
by Willard Myers July 27, 2003

July 27, 2003

I have the same Python 2.3c2+ installed on two different machines here, along with the very useful fpconst module (which is pure Python). On one machine, I can pickle/unpickle (with pickle or cPickle) the constants defined in fpconst; on the other I hit a ValueError on unpickle. I have different versions of Mac OS X on the two machines; can that really cause this behavior? If that were so, I'd expect the first case below to fail and the other to succeed :-< Details: === Works === [abenaki:~] wlmyers% python Python 2.3c2+ (#12, Jul 25 2003, 12:58:00) [GCC 3.1 20020420 (prerelease)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import fpconst, pickle >>> infinity = pickle.dumps(fpconst.PosInf) >>> print infinity FInf . >>> pickle.loads(infinity) Inf >>> type(pickle.loads(infinity)) <type 'float'> >>> import os >>> os.uname() ('Darwin', 'Abenaki.local.', '7.0.0b1', 'Darwin Kernel Version 7.0.0b1: Mon Jun 16 23:01:44 PDT 2003; root:xnu/xnu-452.1.obj~1/RELEASE_PPC ', 'Power Macintosh') === Doesn't work === [mawson:Programming/Python/fpconst-0.6.0] wlmyers% python Python 2.3c2+ (#12, Jul 25 2003, 12:58:00) [GCC 3.1 20020420 (prerelease)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import fpconst, pickle >>> infinity = pickle.dumps(fpconst.PosInf) >>> print infinity FInf . >>> pickle.loads(infinity) Traceback (most recent call last): File "<stdin>", line 1, in ?

FutureWarning in Carbon/Controls.py

While building a wxPython standalone with bundlebuilder.py I got the following warning that I hadn't seen before. Just in case this is an issue for 2.3rc2 I thought I should bring it up here.

1. The real snake is too life-like for an icon. 2. How about the Crushing Foot. Or some flying circus tents. Or a spam can. 3. Why is this a Dutch thing ? 4.
