Re: Running a python program during idle time only

My experience is that properly niced processes can use almost 100 percent CPU, and still not have any noticeable effect on my other use of the computer. Asbj.S. -- Asbjørn Sæbø, post.doc.

I think Joe was trying to encourage you to provide some more information so that someone _can_ help you... Mentioning in the subject that your question is about Twisted would certainly be a step in the right direction, as would at _least_ touching on what you're intending to do, what you've tried, what problems you've encountered, what documentation you've read and what issues you're not following. I have zero experience with Twisted, so I can't provide any help myself, but clearing up your own question might encourage someone who does know to answer.

Re: Access lotus notes using Python
Hi, What I am trying to do is to retrieve data from Lotus Notes Domino server and display the results in some specific format.

So now I am trying Python to get my work done. I downloaded pywin and installed it. I am trying ways to connect to the Domino server, but could not get hold of the API to do so.

If you're in Melbourne, you're a python programmer and you're interested in meeting up, drop me an email and let me know.

Hacking the scope to pieces
We're starting to version a number of our python modules here, and I've written a small function that assists with loading the versioned modules... A module would be called something like: myModule_1_0.py In anything that uses it, though, we want to be able to refer to it simply as 'myModule', with an environment variable (MYMODULE_VERSION - set to 1.0) that defines the version. I've written a module called 'moduleLoader' with the follwing function in: def loadModule(module, version, v = globals()): import compiler loadStr = import %s_%s as %s % (module, version.replace(., _), module) eval(compiler.compile(loadStr, /tmp/%s_%s_errors.txt % (module, version.replace(., _)), single)) v[module] = vars()[module] The ideal situation with this would be to be able, in whatever script, to have: import moduleLoader moduleLoader.loadModule(myModule, os.getenv(MODULE_VERSION)) However, this doesn't work. The two options that do work are: import moduleLoader moduleLoader.loadModule(myModule, os.getenv(MODULE_VERSION), globals()) import moduleLoader moduleLoader.loadModule(myModule, os.getenv(MODULE_VERSION)) from moduleLoader import myModule What I'm after is a way of moduleLoader.loadModule working back up the scope and placing the imported module in the main global scope.

ANN: Leo 4.3 final
Leo 4.3 final is now available at http://sourceforge.net/projects/leo/ Leo 4.3 is here after almost five months of work. The defining features of Leo 4.3: - 1. Leo now stores options in @settings trees, that is, outlines whose headline is '@settings'. When opening a .leo file, Leo looks for @settings trees not only in the outline being opened but also in various leoSettings.leo files. Users can create arbitrarily complex user options with @settings trees. 2. The Preferences command temporarily replaces the outline pane with an outline showing all the @settings trees in effect. The Preferences command also replaces the body pane with a settings pane. This settings pane allows you to change the settings selected in the outline pane using standard gui widgets. 3. Leo now stores recent files information in .leoRecentFiles.txt files. 4. Leo's read/write code in leoAtFile.py has been rewritten to support user-defined tangling and untangling. This is a major cleanup of Leo's core. 5. Leo now contains an excellent Plugins Manager plugin. This plugin enables and disables plugins automatically and tells you everything you need to know about each plugin. This plugin also lets you download plugins from Leo's cvs site. 6. You can install third-party extensions in Leo's extensions directory. Leo will attempt to import such extensions from the extensions directory when normal imports fail. The distribution contains Python Mega Widgets in the extensions directory. What people are saying about Leo Another day, another breakthrough using Leo--now I realize Leo is the best URL bookmark manager there is. No more bookmarks menus or favorites lists inside the browser for me. With the @url directive I can just double click on the URL to open it in my browser. Leo lets me arrange the URLs in a hierarchy (or multiple hierarchies), attach notes to them, save clippings of things I read on the sites. It's sooo much better than anything the browsers have built in and it lets me easily use different browsers on different platforms and different machines (try that with the browsers' built-in bookmark managers). -- Dan Winkler I am an amateur photographer. I use plain old 35mm. film for my pictures. Over the weekend, I used Leo to organize my lists of pictures. It is quite helpful--I can have separate nodes for pictures I have enlarged, as well as pictures I have submitted to our local camera club. Thanks! -- Rich Reis Cloning is pure genius!...

Running PythonNN.DLL as debug or release?
Hi Folks, We've been using Python embedded in an application for a while now, where the Python dll is PythonNN.dll, NN being the version number, such as Python24.dll. Recently it was pointed out to me that Python can run in a debug or release configuration and that you can specify this on the command line using -O and -OO. My question is how do I specify this to the Python DLL I have embedded in my application? Is it as straightforward as: o Use PythonNN.dll for release mode Python o Use PythonNN_d.dll for debug mode Python and if so, how do I specify I want -O or -OO with release mode? I've tried looking at the C API documentation but couldn't find anything useful there. We are using versions of Python from 2.2 upwards.

Re: Python on a public library computer
alex23 wrote: In this case, it sounds like the library is providing computers for two purposes: access to Office tools and to the internet. Given the everything not forbidden is permissable attitude of most people, unless the use is restricted to only those two activities people legitimately wanting access will tend to end up waiting for others who have co-opted the services for their own personal end. But who are those people using this *public* library for their own personal end? Is it the cannibal elite that is using this public space to promote microsoft products and 'reducing' their workload (actually I believe they are making their own job harder) or is it the user who wants to run public domain software? The current situation is such that in order to make the system 'safer' I cannot clear my own cache, so my internet history is visible for the next user, which compromises *my* security. Surely there should be a balance between the interests of the provider and the client, but since in this case the client is also the 'owner' of the service (it's a *public* library) there should be room to run non-proprietary software. The connection with the european constitution is exactly about this shifting of the ownership of public buildings, institutions, infrastructure etc. *from* the persons using the service *towards* the people accidentally working in that place. So social security starts to act like it's an employer, but since they are also the state, they don't have to pay minimum wages, if one is treated unfairly it's impossible to get a fair trial. If one doesn't agree with this treatment they just keep the money they are obliged to pay (according to our national constituton) to themselves. Universities start to act like the buildings are extra living room for the persons working there and in order to get a degree one has to *work* for a professor. The elite in the city starts building luxury appartments for their own people (who are payed with public money stolen one way or the other from the normal residents in the city) in the natural resorts because their is some kind of 'shortage' in the housing market. On the other hand one wants to make the polluter pay and creates taxes for garbage. But these taxes are 'equal' for everyone, meaning that they are negligible for the rich but a large part of the income of the poor. The same goes for fines for speeding or parking tickets. If you're rich or know the people in the elite you can get away with anything. The *european* constitution is related to this because our government wants to limit the discussion to the merits of the document. The problem is that even with a good constitution a corrupt elite can interpret the terms in a way that is unfavorable for the poor (almost anyone is poor or becoming poor by now). And secondly the document is only intelligible for specialists, so even if it was good, there's no way to tell. So we might find ourselves in a situation one day when walking to the water tap to fill our teakettle a voice will come out of it asking whether we want *coca* cola or *pepsi* cola. When complaning about this to our government we will hear something like: 'Look you *have* a choice it's not like we prefer one brand over the other, so what are you complaining about? Be silent out you will be removed from our administration, which means no food, health care, money or friends. I'm currently mentally analogizing this discussion with the one on python dev about whether the decimal module should give users 'what they expect' or conform to industry standards, but I guess one has to be Dutch to see any connection at all here :-) The rationale for all of this is that the economy is bad and we have close to zero growth. We should be like China or other low wage countries in order to be more competitive. However the rationale is false! Because we have better infrastructure here we are *further* up the exponential development curve so we could have fenomenal growth if we wanted! The fact that this isn't happening at all has nothing to do with with the economic potential but all the more with conservative power consolidation tactics. The media play a very nasty role in all of this. For example the newspapers are complaining nobody reads paper anymore because of the internet. IMO it is caused more by nobody wanting to read the same old selfpromotion anymore. Something comparable is happening with public television which is not a true representation of the public opinion at all. Not to say public opinion is always good, but if noone thinks you are giving the right characterization of the current situation, one is not likely to want to join the discussion.

Re: first release of PyPy
Kay Schluehr wrote: Speed isn't even the biggest problem when running PyPy on itself. PyPy still 'fakes' some objects, e.g. borrows them from the underlying Python. Does it mean You create an RPython object that runs on top of CPython, but is just an RPython facade wrapped around a CPython object? yes. It means that there are objects that behave like they should in PyPy but are implemented by keeping creating a regular CPython instance of the object and delegating all calls on PyPy-level back to the CPython level. So You have four kinds of Pythons: RPy - translateable into LL code APy - non-translateable but interpretable by translated RPy RPy* - non-translateable but consistent interface with RPy. Calls APy* APy* - not translateable and not interpreteable by translated RPy Selfhosting would imply vanishing RPy* and APy*. But the problem seems to be that selfhosting must somehow be broken because the system needs to interact with OS-dependend librarys. As long as You run the system upon CPython the problem does not occur but once You drop it, a kind of extension objectspace must be created which is translated into code with nice interfacing properties. Or do You think that RPython translations will be sufficient and another ext-objectspace is just useless epi-cycling? Not exactly sure what you mean here. It's clear that we have to handle faked objects differently to get a stand-alone PyPy version. One possibility would be, that the RPython code calls certain functions which are implemented in Python (can be regular Python), that are not translated but replaced by a proper C function. For example we have a function intmask at the moment which takes a long and removes as many bits from it as neccessary to make it fit into an int again. This function is left out when translating, since in C an int can obviously not overflow to a long. Regards, Carl Friedrich -- http://mail.python.org/mailman/listinfo/python-list

You could use imp.get_suffixes(). In a release build the returned list
will contain these entries
('.pyd', 'rb', 3), ('.dll', 'rb', 3)
in a debug build that will be
('_d.pyd', 'rb', 3), ('_d.dll', 'rb', 3)
Another way would be to look at the filename of any binary extension
module. _ctypes.__file__, for example: '.\\_ctypes.pyd' vs.
'\\_ctypes_d.pyd'.

Kent Johnson had the right approach, with regular expressions.
For a bit of optimization, use non-greedy groups. That will
give you shorter matches.
Suppose you want no more than 10 bases between terms. You could
use this pattern.
a.{,10}?t.{,10}?c.{,10}?g.{,10}?
import re
pat = re.compile('a.{,10}t.{,10}c.{,10}g.{,10}?')
m = pat.search(tcgaacccgtagctaatcg)

pat.search(tcgaacccgtagctaatttg)
_sre.SRE_Match object at 0x9b950
pat.search(tcgaacccgtagctaag)
If you want to know the location of each of the bases, and
you'll have less than 100 of them (I think that's the limit)
then you can use groups in the regular expression language

Re: Hacking the scope to pieces

However, I couldn't get it to import... The route I've ended up going (which is just about as simple) is just to return the new module from moduleLoader.loadModule, so my loading code is: import moduleLoader myModule = moduleLoader.loadModule(myModule, os.getenv(MODULE_VERSION)) I've also switched over to using 'inp' for this, rather than creating a compiler string - much nicer Anyway, thanks Skip -- Hugh -- http://mail.python.org/mailman/listinfo/python-list
Tk and raw_input segfault
Python newbie disclaimer on
I am running an app with Tkinter screen in one thread and command-line
input in another thread using raw_input(). First question - is this
legal, should it run without issue? If not can you point me to a
description of why.
While updating objects on the screen I get a segfault after an
indeterminate number of updates. It doesn't seem to matter how quickly
the updates occur, but it does segfault faster when there are more
objects on the screen ( as I said failure time seems to have a random
factor added to it ).
Commenting out the raw_input() makes problem go away. I can schedule
as many updates as I wish without error. And it doesn't seem to matter
if I actually hit any keys for raw_input(), it can just sit there.
I have read other posts about readline library failures with Esc O M
sequences and could not recreate those failures.
This happens on 2 separate machines

I have tried to simplify the code as much as possible to make error
more visible( no actual updates of the screen etc ) I've uncommented
the after code line so it fails much more rapidly. I know its ugly
repeatedly scheduling the after but, the same code runs without the
raw_input, and it shows the error more readily.
To see the error start the code and click the button repeatedly until
it segfaults. It will still segfault if you remove the 'command'
funtion and call update dirctly - it just takes a bit longer and your
wrist will probably get tired.
Thanks in advance for any responses.

Re: staticmethod and classmethod
C Gillespie [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Hi, Does anyone know of any examples on how ( where) to use staticmethods and classmethods? A python class method is closer to a Java static method than a python static method. Class methods can be useful if you want to be able to change objects in the class, or if you want to be able to use inheritance, neither of which python static methods allow you to do cleanly. Another, and rather esoteric use, is to use the class as its own instance. I find that static methods are useful when I want to import a class from a module, and don't want to import the module itself or a lot of bits and pieces from the module. The class gives a place to park the method, and also lets you use inheritance, neither of which putting it into the module does.

Another technique that you might want to consider, is to have an

v[module] = vars()[module]
The ideal situation with this would be to be able, in whatever

to have:

moduleLoader.loadModule(myModule, os.getenv(MODULE_VERSION))
However, this doesn't work. The two options that do work are:

Re: Running a python program during idle time only
Yes it should. The problem is that I notice a loss in performance when the program is running at 100% CPU. Even though it is nice, if you try to open up new applications, or switch between them, you notice your computer lagging a little bit. That's why even though I'm not using the cpu that much as I'm just reading my email, or browsing the web, I wouldn't necessarily want the indexing program to be running at full pace. If you use google's desktop program, you'll notice that once the computer has been idle for a few minutes your CPU will go to 100%, but as soon as you move your mouse, or hit a keystroke the cpu will drop to 5-10% usage. That's the behavior I'm trying to achieve. Thanks David for your suggestions. That seems to be what I was looking for.

Re: Encryption with Python?
For your own good, please change your credit card number now! You have obviously lost your mind. Please read Applied Cryptography if you are wondering why I would say this. I am not trying to be mean. For example: I have access to 80 Pentium 3 cpus (at ~1.8 GHz) and have engineered a simple brute force on this (in pure python) that can check 2**31 integers overnight. I timed it. I used absolutely NO optimization. Also, beyond these 2**31 integers, I stopped trying because I have other things to do--I had no incentive. Now your credit card info is on the line. I'm a rank ammy and I'm sure a skilled programmer could speed it up 100 to 1000 fold (1000 ~ 2**10). Also, this was for your first message about which I knew positively nothing. You have made the job now several times easier (lets say 10 ~ 2**3) by disclosing the nature of the plain text. If you think that there are lots of keys that map some part of your cipher text to a set of 16 numbers (+/-) separators, you are right. But they would be some small fraction of the total keyspace. 10**6 such keys could be stored easily and so second and later rounds of analysis would be trivial. So lets do some math. Say someone had the same computing power as I do. Say, we could start with 2**32 keys in 24 hours or 1 day. Now lets say they are a good programmer: 2**32 * 2**10 keys/day. Now lets say they take full advantage of knowing the nature of the plain text: 3**32 * 2**10 * 2**3. Lets say they put 2 weeks of computing time into it: 14 days ~ 2**4 days. Of course both + and - integers are possible, so we'll divide our final answer by 2 later. So, say you had a highly motivated, reasonably adept programmer whose lack of cryptanalysis knowledge limited himself to brute force--but he had a lot of computers and 2 weeks to work with--and was checking both + and - integers: 2**(32+10+3+4-1) = 281474976710656 That's 15 digits. That is a telephone number (with area code) and a 5 digit zip. That's 2 birthdays, easy. That is easily the hash of any hashable python object (only 2**32 possibilities for these). Do you get the point? Basically, these 15 digits are about the limit of any managable key. Now, lets say you have someone skilled at cryptanalysis. Well, they are probably already trying to figure out what they want to buy first. Normally I wouldn't warn you of this, but I am positively certain that someone smarter than me will be spending on your credit card and I want to spoil their holiday.

Namely, he immediately realized that hang gliders dissipated less energy in stable flight than any other aircraft in existence, not because the flew so well--they didn't--but because of their low weight. He calculated that a twenty-kilogram hang glider with a wing span of close to thirty meters would dissipate no more than one third of a horse power or thereabout and that is an amount of energy a competition cyclist generates over the course of a race. After winning the prize, MacCready challenged himself to fly across the English channel and started building an improved second version of his airplane. Passing through Los Angeles I went to see the project in a Long Beach hangar and took the opportunity to pick MacCready's brain for the benefit of our own magazine. Referring to his article I confessed my surprise that a scientist of his caliber would be inspried by such crude aeronautical engineering hacks as hang gliders unquestionably were. His reply was this: I also consider myself an amateur. I have a PhD in aeronautics, but not in aeronautical engineering. But this just might have been my advantage. All these many previous failed attempts had been made by people with better engineering credentials. If their conception of possible solutions was better defined, it was probably also more constrained by

Indeed I have written PEP 302-based code to import from a relational database, but I still don't believe there's any satisfactory way to have [such a hooked import mechanism] be a first-class component of an architecture that specifically requires an os.py to exist in the file store during initialization. I wasn't asking for an import hook mechanism (since I already knew these to exist), but for a way to allow such mechanisms to be the sole import support for certain implementations. We do not have os.py (directly) on the file system. It lives (like everything else) in a zip archive. This works because the zipimporter is put on sys.path_hook before the interpreter starts executing Python code. Thus, all you have to do: use a different Python startup and ensure that you special importer (able to import e.g. os) is already set up, before you start executing Python code.

Re: python24.zip
Martin v. Löwis [EMAIL PROTECTED] writes on Sun, 22 May 2005 21:24:41 +0200: ... What do you mean, unable to? It just doesn't. The original question was: why does Python put non-existing entries on 'sys.path'. Your answer seems to be: it just does not do it -- but it might be changed if someone does the work. This fine with me. ... In the past, there was a silent guarantee that you could add items to sys.path, and only later create the directories behind these items. I don't know whether people rely on this guarantee. I do not argue that Python should prevent adding non-existing items on path. This would not work as Python may not know what existing means (due to path_hooks). I only argue that it should not *itself* (automatically) put items on path where it knows the responsible importers and knows (or can easily determine) that they are non existing for them. ... The application was Zope importing about 2.500 modules from 2 zip files zope.zip and python24.zip. This resulted in about 12.500 opens -- about 4 times more than would be expected -- about 10.000 of them failing opens. I see. Out of curiosity: how much startup time was saved when sys.path was explicitly stripped to only contain these two zip files? I cannot tell you precisely because it is very time consuming to analyse cold start timing behavior (it requires a reboot for each measurement). We essentially have the following numbers only: warm startcold start (filled OS caches)(empty OS caches) from file system5s 13s from ZIP archives 4s 8s frozen 3s 5s The ZIP archive time was measured after a patch to import.c that prevents Python to view a ZIP archive member as a directory when it cannot find the currently looked for module (of course, this lookup fails also when the archive member is viewed as a directory). Furthermore, all C-extensions were loaded via a meta_path hook (and not sys.path) and sys.path contained just the two Zip archives. These optimizations led to about 3.000 opens (down from originally 12.500). I would expect that importing 2500 modules takes *way* more time than doing 10.000 failed opens. You may be wrong: searching for non existing files may cause disk io which is several orders of magnitude slower that CPU activities. The comparison between warm start (few disc io) and cold start (much disc io) tells you that the import process is highly io dominated (for cold starts). I know that this does not prove that the failing opens contribute significantly. However, a colleague reported that the import.c patch (essential for the reduction of the number of opens) resulted in significant (but not specified) improvements.
