Hi, Anybody from the pythonmac-sig going to see Guido Wednesday? I'm heading in from mid-peninsula by Caltrain; I hope to get to the cafe nextdoor around 7:15 pm so I can grab a sandwich. If someone's going and they want to meet up, send me some email. Bob Savage savageb(a)pacbell.net BTW, I intend to go to the

Error in PyDebugger.py / bdb.py
by savageb July 18, 1999

July 18, 1999

I have been getting an error message whenever I try to clear a breakpoint (that is either by clicking on a breakpoint in the source window, or deleting from the 'edit breakpoints' window). TypeError: too many arguments; expected 2, got 3 file PyDebugger.py; line no. 563, in clear_break bdb.Bdb.clear_break(self, filename, lineno) This seems to happen consistently. The only way I have figured out how to clear breaks is to copy the code out of the file, throw the old file away, and paste the code into a clean file. If I try to "clear all breaks" I get a KeyError. file bdb.py; line 231, clear_all_file_breaks blist = Breakpoint.bplist[filename, line]

Reentrancy is when a routine can be re-entered at the point it was left. For pre-emptive multitasking, this is a must. If you have a routine "getColor" that was 114 instructions, and two important processes were wanting access to that task at the same time, one would have to wait for the other to finish before it could execute in a non-reentrant system. In a reentrant system, they would basically execute simultaneously as one would go in a few instructions and then have its state saved while the other went in, and then the first would "re-enter" the routine where it left off and continue a ways, and so forth. Much of the core Mac OS Toolbox is non-re entrant code. This has held back the so-called "advanced" OS features such as true multitasking and multithreading. BeOS, OS/2, and Amiga OS are full of reentrant code and are very multitaskable. (teehee, no spelling suggestions on that word). Carbon in MacOS X is scheduled to fix a lot of these problems. In MacOS 8 (or any carbonlib capable Mac OS prior to 10), Carbon calls will map to the non-reentrant older Toolbox code, while in Mac OS X they will get to use the new libraries. I imagine a Carbon port of MacPython could easily be thread-safe. The above information is on an AFAIK basis, I could easily be wrong as I'm still trying to grok Carbon and I haven't gone into Mac OS X for a few days now due to other importances. FWIW, TipTop claims that Objective Everything is (or will be) usable with Carbon, opening up another cross-language (Python/Perl/TCL) scripting solution. If they would only release a Python 1.5.x based version of OE!!!!!!! wishing-very-much-he-could-see-the-carbon-compliant-macoffice-2000-build'ly yrs in stereophonic high speed master suite from the penthouse, .jPS

Just curious. Well, MacPython doesn't have threads yet, so that problem is pretty much solved:-) And reentrancy probably means here that you can't use Minotaur to call from Python to TCL and then back to Python (or something else). -- Jack Jansen | ++++ stop the execution of Mumia Abu-Jamal ++++ Jack.Jansen(a)oratrix.com | ++++ if you agree copy these lines to your sig ++++ www.oratrix.nl/~jack | see http://www.xs4all.nl/~tank/spg-l/sigaction.htm

Minotaur looks pretty neat! Maybe someone could pick it up and see how much work a Mac port would be?

An Odd Question...
by Richard Gordon July 8, 1999

July 8, 1999

OK, I will risk being branded the list idiot if you will be patient enough to hear me out. What I want to know is whether it is possible to embed Perl in Python, Mac or otherwise? Or maybe I am just talking about calling Perl scripts from executing Python scripts? To answer the "why the hell would anyone want to do that?" question, I know more Perl than Python and have Perl running on web sites that people paid me $$$ to do. I don't actually hate Perl, but I prefer Python, and would like to migrate at least one of these to an all-Python system eventually so I can get someone to pay me $$$ to do a Python site. Not too surprisingly, I haven't found anything that will do something like a batch migration and nobody is going to pay me to reinvent the wheel, so this will have to be done over a period of time at my own expense (all the while overcoming the resistance of webmasters who are suspicious of Python because "there aren't many other Python programmers around here (Atlanta)." Additionally, I understand regex in Perl a lot better than I do in Python and, to this point at least, it appears to me that Perl's regex is stronger. Offsetting that entirely is the culture of the Perl community vs. the Python community, but it would still be nice to use some Perl selectively. Anyway, I hope that this isn't an overwhelmingly absurd question and, given the predominance of Perl in web things, I wouldn't think that I'm the first one to wonder about it. What I'm looking for is some general guidance about Python/Perl integration under both MacOS and *nix. Thanks.

If nothing else you could trigger a perl script from within Python - for example on *nix you could make an os.system call. As to the Mac, I started using python because I was using AppleScript to do some workflow automation and decided that if I could just write this one little section in Python it would be sooo much easier, and succesfully integrated a littled bit of Python by launching the script (tell the finder to open it and it runs). So it should be possible to do some stuff. good luck, Bob Savage

Or maybe I am just talking > about calling Perl scripts from executing Python scripts? My gut feeling is that this is imposible, because of the two runtime systems. On the other hand, TCL/TK has been neatly integrated in Python, so maybe it is doable after all. I don't see any mac-specific issues up front, so it might be worhtwhile to ask the general Python community whether someone has done any work on this. -- Jack Jansen | ++++ stop the execution of Mumia Abu-Jamal ++++ Jack.Jansen(a)oratrix.com | ++++ if you agree copy these lines to your sig ++++ www.oratrix.nl/~jack | see http://www.xs4all.nl/~tank/spg-l/sigaction.htm
