ANN: Jug 0.9.1. Parallel Programming Framework
Hello List, This is to let you know of a new release of Jug. Jug allows you to write code that is broken up into tasks and run different tasks on different processors (even across a cluster). Jug is a pure Python implementation and should work on any platform. WHAT'S NEW Version 0.9.1 contains a few minor improvements and several bugfixes. In particular, Tasklet usage is a lot less buggy (previously, several uses would trigger idiotic bugs, now they work as they should).

Ann: New Stackless Website
I'm very happy to announce == Stackless Python has a New Website == Due to a great effort of the Nagare people: http://www.nagare.org/ and namely by the tremendous work of Alain Pourier, Stackless Python has now a new website! This is no longer Plone based, but a nicely configured Trac site. The switch to it has happened right now, the old website will be around for a few days under http://zope.stackless.com while the new site is accessible as http://www.stackless.com stackless.com now allows the source to be browsed (an hourly updated clone from hg.python.org) and includes a new issue tracker. Please let me know if you encounter any problems. cheers -- Chris -- Christian Tismer :^)mailto:tis...@stackless.com tismerysoft GmbH : Have a break!

[newbie] Equivalent to PHP?
Hello I'm an amateur programmer, and would like to know what the main options are to build web applications in Python instead of PHP. I notice that Python-based solutions are usually built as long-running processes with their own web server (or can run in the back with eg. Nginx and be reached through eg. FastCGI/WSGI ) while PHP is simply a language to write scripts and requires a web server (short running processes). Since web scripts are usually very short anyway (user sends query, server handles request, sends response, and closes the port) because the user is waiting and browsers usually give up after 30 seconds anyway... why did Python solutions go for long-running processes while PHP was built from the start as short-running processes? Thank you. -- http://mail.python.org/mailman/listinfo/python-list

It's an artefact of the server infrastructure, there is no rule here. Any solution used with one language could be used with the other.

You misunderstand the problem here. It's not about the duration of the actions, it's about the latency it takes to read/parse/execute the script. HTTP is stateless anyway, so if the same interpreter handles several requests, what you save by keeping the interpreter alive is the load/parse phase. If you relaunch an interpreter for every HTTP request, you pay the same price again and again for something which is not even related to your scripts' execution. -- Alain. -- http://mail.python.org/mailman/listinfo/python-list

Think of it as Apache + PHP versus Python. Apache keeps running, it's only your PHP script that starts and stops. With a long-running process, you keep everything all in together, which IMHO is simpler and better. ChrisA -- http://mail.python.org/mailman/listinfo/python-list

Perl, Ruby, Python and PHP also can do the same thing. You can use a persistent program which is loaded/parsed/compiled once and kept into memory and it will just answer the requests, or you can create a program which is loaded/parsed/compiled on each request. The first way is much better for performance reasons but it consumes much more memory and it is more complicated, because the programs can have memory leaks (they will consume more and more memory after a long period), while the second way is more simple to do, but the performance is not great. Most PHP programs are done using the second way, because it is much simple to do and it is much simple to configure the environment for it, and most of the free web hosting sites that offer PHP support don't offer something better. And... most of the sites don't need a very good performance, because they usually don't have millions visitors per day. Also, most of the sites made in PHP use low level programs using only what the default PHP distribution installed on the server offers, so no web frameworks, or form managers, or templating systems or many other modules that can do a part of the work. The PHP distribution has compiled C programs which run pretty fast, while loading/parsing/compiling a lot of other modules made in Ruby/Perl/Python/PHP would decrease the performance, so a persistent environment is usually required in case those modules are used. And usually Python and Perl and Ruby programs use a lot of modules because for these languages there are a lot of modules available that can do a lot of things for free, while for PHP there are much fewer, and even if there are, (because there are templating systems and web frameworks for PHP also), they are much seldomly used, because those who choose to use a broken language like PHP, usually choose it not only for its main advantage regarding the easiness of deployment, but choose it because it is much more simple and easy to learn, and they usually don't like to learn a lot of other modules. Otherwise... if you want you can also create a web app using PHP and CodeIgniter web framework and run it with fastcgi... Octavian -- http://mail.python.org/mailman/listinfo/python-list

I think that you just answered your own question in the first line of that paragraph. With computers running so fast and memory and disk being so cheap, the only decision left for most applications is what language do you prefer. Python wins because it is so nice to work with. It's clean and you don't have to deal with the daily security holes of PHP. Apparently, very few people use Python à la PHP, ie. Python code embedded in web pages? I guess I am in the minority then. I do plan to turn one of my larger projects into a standalone web server some day but so far writing simple Python CGI scripts has served me fine.

I don't think it is a proper description of the situation (please, somebody correct my mistakes, I am not 100% sure about it myself). WSGI applications (which is basically all web applications in Python) could run in the hosted servers (using for example mod_wsgi for Apache), and I would expect that it is the situation with most production uses. From the programmer's point of view WSGI application (read http://en.wikipedia.org/wiki/Wsgi) is just one script which takes HTTP request on input and generates HTTP Response on output, so it is actually quite simple. And actually quite similar to what JSGI, PSGI, and Rake do (I am not sure who was first whether WSGI or Rake). anyway... why did Python solutions go for long-running processes while PHP was built from the start as short-running processes? It is all about caching ... I am not sure how it is done exactly, but I would expect for example mod_wsgi to cache parsed Python script in memory as well.

using identifiers before they are defined
I'm puzzled with the following example, which is intended to be a part of a module, say tst.py: a = something(5) def something(i): return i When I try: - import tst The interpreter cries out: Traceback (most recent call last): File stdin, line 1, in module File tst.py, line 11, in module a = something(5) NameError: name 'something' is not defined I know that changing the order of the definitions will work, however there are situations in which referring to an identifier before it is defined is necessary, e.g., in crossed recursion. So I modified my module: global something a = something(5) def something(i): return i And this was the answer I got from the interpreter: - import tst Traceback (most recent call last): File stdin, line 1, in module File tst.py, line 12, in module a = something(5) NameError: global name 'something' is not defined Do you have any comments?

In Python, def is a statement, not a declaration. It binds the body of the function to the name when the def statement is run. A Python script is, basically, run from top to bottom, and both def and class are actually statements, not declarations. A function can refer to another function, even one that hasn't been defined yet, provided that it has been defined by the time it is called. For example, this: def first(): second() def second(): pass first() is OK because it defines function first, then function second, then calls first. By the time first calls second, second has been defined. -- http://mail.python.org/mailman/listinfo/python-list

Mutual recursion isn't a problem: the following strange expression of factorial works fine: def strange_helper(x): return factorial(x) def factorial(x): if x==0: return 1 else: return x * strange_helper(x-1) print factorial(5) The reason is names are never looked up when the parser sees them, but rather only when execution reaches them. So the fact that 'factorial' hasn't been defined yet when the parser is dealing with 'strange_helper' is fine, because when 'strange_helper' is actually *called*, 'factorial' has been defined.

Provide a template config file with lots of explanatory comments, and (crucially) every config entry given, commented out, and set to its default. # Configures the default and maximum flurble percentages # Flurblization increases from the default until either the maximum is # reached, or max_sort_memory is exceeded, whichever comes first. #flurble_default = 10 #flurble_max = 30 Having all your defaults in one place makes it easier to produce this sort of file; in fact, you could have your documentation there as well. It does become a little more maintenance work, though. It's possible to have a hybrid, where you run a preprocessor over your code that analyzes it, collects all config entries, and builds your config file parser... but that may be beyond the scope of your project. Anything you can imagine can be done in code. It's just a question of how much work. :) Chris Angelico -- http://mail.python.org/mailman/listinfo/python-list

Also, it plays very nicely with the MUD style of process, which is something I do a lot with Pike. Plus, if you manage it right, you have a guarantee that you can never be in a half-updated state - that's somewhat tricky when you have inter-dependencies in PHP code and the file system itself manages things. What happens if a request comes in while you're half-way through uploading new code to the server? By default, you could use half old code and half new code.

[issue15003] make PyNamespace_New() public
Éric Araujo mer...@netwok.org added the comment: Is this documented in whatsnew? I'm not sure what has been (none of my patches have done so). Okay; if a committer does not add a note we can open a doc bug to not forget that. Also, I remember a discussion about making it public or not, but don’t recall a decision. Amaury brought it up in msg162127. His point was that the type is public in Python, so why not the C API? Actually I was talking about making it public at all, i.e. in Python too. The use cases are different for the different types. StructSequence/namedtuple provides fixed data structures for structured records. A dict is essentially the opposite: an un-fixed data structure for dynamic namespaces, making no firm promises as to what the future holds. Right; I just don’t see why the clock info needs to be a dict instead of a structseq or simplenamespace, but maybe it’s explained in the PEP and I missed it. Also it seems to me that the only advantage of simplenamespace over structseqs is that it has no order and can’t be unpacked; I don’t find that a very strong argument (I do see its value, e.g. “major, minor, *etc = sys.version_info” makes sense but we really don’t want to assign order to sys.implementation elements), but I guess this ship has sailed when the implementation was approved. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15003 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15048] Manually Installed Python Includes System Wide Paths
James Kyle b...@jameskyle.org added the comment: I think Ned does have some good points regarding the minimal impact a reversion would have. The most poignant point is that /Library/ on OS X is not a user controlled directory whereas ~/.local is. If ~/.local exists and has packages installed, it's because the user has made a conscious choice. If they regret that choice, they can remove ~/.local. Every package installed in ~/.local is the result of direct action by the user impacted. The same cannot be said for /Library. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15048 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue12982] Document that importing .pyo files needs python -O
Terry J. Reedy tjre...@udel.edu added the comment: Michael, you should ask the closed source library distributor to distribute all files as .pyc so you have access to docstrings while programming and to avoid the problem with reading them. He could also distribute an all-.pyo version. A mixture seems accidental. Is the import restriction currently intended? If a change *is* made, should it be regarded as an enhancement rather than a bug fix? I asked both question on pydev for more input. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12982 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue15044] _dbm not building on Fedora 17
Ross Lagerwall rosslagerw...@gmail.com added the comment: The gdbm provided with Fedora 17 provides /usr/include/ndbm.h. This makes setup.py think that it should try link with -lndbm when it actually requires -lgdbm_compat. A workaround is to specify --with-dbmliborder=gdbm to force gdbm to be used.

[issue12510] IDLE: calltips mishandle raw strings and other examples
Roger Serwy roger.se...@gmail.com added the comment: The _self_pat RE needs to be changed to just remove the first argument. Presently, another bug exists with the current implementation: class A: def t(self, self1, self2): pass a = A() a.t( gives (1,2) as the calltip, instead of (self1, self2) for 3.x. Python 2.7 gives the correct calltip. The attached patch modifies _self_pat to remove only the first argument, modifies the classmethod test, and adds a test for notself, as Terry requested in msg162511. -- Added file: http://bugs.python.org/file25942/issue12510_self_pat.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12510 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue4442] document immutable type subclassing via __new__
Chris Withers ch...@simplistix.co.uk added the comment: It's the fact that for immutable types, initialization is done in __new__ instead of __init__ that isn't documented anywhere. This should be Python-level rather than C-level documentation.
