wxPython, Syntax highlighting
Hi, I am looking for wx widget that has the ability to show text, edit the text (like a TextCtrl) but also does syntax highlighting (if the text is e.g. XML or HTML). I have been looking in the latest wxPython version but I could not really find anything. Any suggestions?

It can be costly, though, finding the implementation you want/need for any specific environment. Gfortran, which supports Fortran 95 and a little of Fortran 2003, is part of GCC and is thus widely available. Binaries for g95, also based on GCC, are available for more than a dozen platforms, including Windows, Mac OS X, and Linux. I use both and consider only g95 mature, but gfortran does produce faster programs. Intel's Fortran compilers cost about $500 on Windows and Mac OS and $700 on Linux. It's not free, but I would not call it costly for professional developers. Speaking of money, gfortran and g95 have free manuals, the latter available in six languages http://ftp.g95.org/ . Final drafts of Fortran standards, identical to the official ISO standards, are freely available. The manual for Numpy costs $40 per copy.

Don't the bytecodes call underlying OS functions? - so is there not a case where a particular bytecode could block, or all they all protected by time outs? I beleive the convention is when calling an OS function which might block the global interpreter lock is dropped, thus allowing other python bytecode to run. Embedded code would handle this sort of thing by interrupting anyway and trying to clear the mess up afterward - if the limit switch does not appear after some elapsed time, while you are moving the 100 ton mass, you should abort and alarm, regardless of anything else...

Although still not mature enough for general use, PyPy 1.0 materializes for the first time the full extent of our original vision: - A flexible Python interpreter, written in RPython: - Mostly unaware of threading, memory and lower-level target platform aspects. - Showcasing advanced interpreter features and prototypes. - Passing core CPython regression tests, translatable to C, LLVM and .NET. - An advanced framework to translate such interpreters and programs: - That performs whole type-inference on RPython programs. - Can weave in threading, memory and target platform aspects. - Has low level (C, LLVM) and high level (CLI, Java, JavaScript) backends. - A **Just-In-Time Compiler generator** able to **automatically** enhance the low level versions of our Python interpreter, leading to run-time machine code that runs algorithmic examples at speeds typical of JITs! Previous releases, particularly the 0.99.0 release from February, already highlighted features of our Python implementation and the abilities of our translation approach but the **new JIT generator** clearly marks a major research result and gives weight to our vision that one can generate efficient interpreter implementations, starting from a description in a high level language.

Technically, PyPy is both a Python interpreter implementation and an advanced compiler, or more precisely a framework for implementing dynamic languages and generating virtual machines for them. The framework allows for alternative frontends and for alternative backends, currently C, LLVM and .NET. For our main target C, we can can mix in different garbage collectors and threading models, including micro-threads aka Stackless. The inherent complexity that arises from this ambitious approach is mostly kept away from the Python interpreter implementation, our main frontend. PyPy is now also a Just-In-Time compiler generator. The translation framework contains the now-integrated JIT generation technology. This depends only on a few hints added to the interpreter source and should be able to cope with the changes to the interpreter and be generally applicable to other interpreters written using the framework. Socially, PyPy is a collaborative effort of many individuals working together in a distributed and sprint-driven way since 2003. PyPy would not have gotten as far as it has without the coding, feedback and general support from numerous people. Formally, many of the current developers were involved in executing an EU contract with the goal of exploring and researching new approaches to language and compiler development and software engineering. This contract's duration is about to end this month (March 2007) and we are working and preparing the according final review which is scheduled for May 2007. For the future, we are in the process of setting up structures to help maintain conceptual integrity of the project and to discuss and deal with funding opportunities related to further PyPy sprinting and developments.

using PyUnit to test with multiple threads
Is it possible to use PyUnit to test with multiple threads? I want to send many commands to a database at the same time. The order of execution of the commands is indeterminate, and therefore, so is the status message returned. For example, say that I send the commands get and delete for a given record to the database at the same time. If the get executes before the delete, I expect a success message (assuming that the record exists in the database). If the delete executes before the get, I expect a failure message. Is there a way to write tests in PyUnit for this type of situation? Thank you in advance. Winston -- http://mail.python.org/mailman/listinfo/python-list

Re: Python automatic testing: mocking an imported module?

Heyas
So we have the following situation: we have a testee.py that we want
to automatically test out and verifiy that it is worthy of being
deployed. We want our tester.py to test the code for testee.py
without changing the code for testee.py. testee.py has a module in it
that we want to mock in some tests and in others use the real module.
/foo.py: (real module)
class bar:
def __init__(self):
I am real
/foo_fake/foo.py: (fake module)
class bar:
def ___init__(self):
I am a banana
/testee.py:
import foo
foo.bar()
/tester.py:
from foo_fake import foo
foo.bar()# prints I am a banana
testee.py # also prints I am a banana
import foo
foo.bar() # prints I am real
testee.py # also prints I am real
This isnt working as we would like, does anyone have any tips on how
to get something like this working?
If you add the foo_fake directory to the front of sys.path, import foo
will import the foo.py in foo_fake directory before the one in the local
directory.
# unverified code
import sys
sys.path.append(0,'foo_fake') # add foo_fake to front of path
import foo
foo.bar()
execfile('testee.py')
sys.path.pop(0) # remove foo_fake
reload(foo)
foo.bar()

That last part is important, because that's also how many other people have interpreted this particular feature. You are right. The feature is more situated on a syntactical / interface level. The semantical level has to be specified by annotation handlers. Among them there will also be those that deal with type annotations. I have little doubts that one of them will make it into the stdlib sooner or later and might also influence compilation. I seem to recall that some of the PyPy people weren't interested in static analysis [1], so I'm skeptical about whether type annotations are their kind of thing, either. That's why I asked the question with regard to Py3K style annotations and not static analysis in Py2X which I consider intractible. The JIT measures types at runtime and optimizes code using this information but doing things in this style global optimizations are hardly tractible as well. My main interest is in an intermediate level, given type measurements as a byproduct of UTs and code coverage. This methodology is process-oriented and non interferent. That said, I imagine that the handling of metadata (including type details) is an element in the way RPython works, but I also imagine that things get more complicated as such metadata diverges from plain type information and into arbitrary observations about other aspects of program behaviour. RPython is heuristically defined as a subset of Python static enough to be translatable to C. So it is actually static analysis that is done here, not on a local scale but on a simpler sublanguage. It is not clear to me whether for a sufficiently annotated Py3K program the inequation RPython != Python still holds?

Re: Fortran vs Python - Newbie Question
I feel obligated to fan the flames a bit by pointing to http://www.fortranstatement.com/ a site which advocates discontinuing development of Fortran and does a good job of summarizing the problems with the contemporary development of that language. I am not convinced that a new high performance language (Chapel, Fortress, etc.) is necessary. Rather, I feel that FORTRAN 77 is a mature tool, and that it, in combination with a powerful dynamic language (Python being my choice) is entirely sufficient for any foreseeable scientific computing. Fortran 90 and successors (F9* in the following) provide a baroque and elaborate effort to bolt modern computing methods over a finely honed special purpose tool (F77) that manages large numerical arrays spectacularly well. It is as if you decided to add a web search engine (an elaborate, developing set of requirements) to grep (a finely honed special purpose tool). It makes much more sense to add greplike features to your websearch tool than to try to foist Grep95 (competing with the Google search engine) on everyone who ever needs to find a misplaced text file. F77 interfaces smoothly and neatly with Python. F9* continues to be the single most difficult case for interoperability with any other contemporary algorithmic language. Fortunately there is hope within the new standard, where an interoperability flag will force F2003 to deliver arrays that are exportable. In exchange for this balkiness, F9* offers crude and verbose implementations of encapsulation and inheritance. I am sure Dr Beliavsky and some others are productive with F9*, but I would strongly advocate against it for anyone in a position to make a choice in the matter. Some people are competent with hand-powered drills, but I wouldn't set up a furniture production line with them on that basis. The performance and library advantages of Fortran are all available in F77. Higher level abstractions can easily be wrapped around the low level structures using Python and f2py. Making the combination performance-efficient requires some skill, but making a pure Fortran implementation efficient does no less so. I don't think we should or can abandon the excellent infrastructure provided by the Fortran of a generation ago. However, I am totally unconvinced that there is a point to a backward compatible extension to F77 that tries to support OOP and other abstractions unimaginable in the early days of Fortran. F77 and its numerical libraries are mature and complete. I think we should treat it as a remarkable set of packages, and move on. For any purposes I know of not involving an existing F9* legacy, I believe that Python plus F77 is as good as or superior to F9* alone. This includes the total time needed to learn the tools, (I think it is easier to learn Python, F77 and f2py than to learn F9* alone to any comparable skill level.) total time needed to develop the code, whole system performance, testability and maintainability. Once Python gets a first-class array type things will be even smoother as I understand it. mt -- http://mail.python.org/mailman/listinfo/python-list

To get python to run the __get__ method I think you have to call
__getattr__ explicitly:
a.__getattr__('test')
If you do:
a.test
python follows a different routine: it checks for the existence of the
attribute, then check if there is a __getattr__ attribute. Now the
speculative bit: then I conjecture that python assumes that
__getattr__ is a function with two arguments and directly passes them
on to it. Indeed
type(a).__dict__['__getattr__'](a, 'test')
seems to produce the same errors as a.test, whether the instance
attribute is set or not.
And this explain why there are too many arguments (error message

Although still not mature enough for general use,PyPy1.0 materializes for the first time the full extent of our original vision: - A flexible Python interpreter, written in RPython: - Mostly unaware of threading, memory and lower-level target platform aspects. - Showcasing advanced interpreter features and prototypes. - Passing core CPython regression tests, translatable to C, LLVM and .NET. - An advanced framework to translate such interpreters and programs: - That performs whole type-inference on RPython programs. - Can weave in threading, memory and target platform aspects. - Has low level (C, LLVM) and high level (CLI, Java, JavaScript) backends. - A **Just-In-Time Compiler generator** able to **automatically** enhance the low level versions of our Python interpreter, leading to run-time machine code that runs algorithmic examples at speeds typical of JITs! Previous releases, particularly the 0.99.0 release from February, already highlighted features of our Python implementation and the abilities of our translation approach but the **new JIT generator** clearly marks a major research result and gives weight to our vision that one can generate efficient interpreter implementations, starting from a description in a high level language.

Technically,PyPyis both a Python interpreter implementation and an advanced compiler, or more precisely a framework for implementing dynamic languages and generating virtual machines for them. The framework allows for alternative frontends and for alternative backends, currently C, LLVM and .NET. For our main target C, we can can mix in different garbage collectors and threading models, including micro-threads aka Stackless. The inherent complexity that arises from this ambitious approach is mostly kept away from the Python interpreter implementation, our main frontend. PyPyis now also a Just-In-Time compiler generator. The translation framework contains the now-integrated JIT generation technology. This depends only on a few hints added to the interpreter source and should be able to cope with the changes to the interpreter and be generally applicable to other interpreters written using the framework. Socially,PyPyis a collaborative effort of many individuals working together in a distributed and sprint-driven way since 2003. PyPywould not have gotten as far as it has without the coding, feedback and general support from numerous people. Formally, many of the current developers were involved in executing an EU contract with the goal of exploring and researching new approaches to language and compiler development and software engineering. This contract's duration is about to end this month (March 2007) and we are working and preparing the according final review which is scheduled for May 2007.

Re: newbi question on python rpc server, how it works?
I've built a bit of an account provisioning/support framework here based on SimpleXMLRPCServer (which is the one bundled w/ Python). Take a look at http://docs.python.org/lib/module-SimpleXMLRPCServer.html as it also includes a bit of a code example. It seems to work fine for my needs in that I only server between 5 - 6 requests a minute. All XML-RPC calls translate into one or more LDAP calls. I've about ten clients connecting at random times. I've set it up to run on localhost:8080 and then I use Apache+mod_ssl+htaccess+mod_proxy to provide some security. Direct requests are sent to https://user:[EMAIL PROTECTED]/RPC2 and proxied internally back to the XMLRPC server. Twisted might be an easier option though as you'll not have to deal with all of the daemonization details. Also, check out http://www.xmlrpc.com for protocol details.

The only difference is where a specific object is initialized, and therefore which method you have to override. __new__ is a static method (it doesn't need to be declared as one, this is done automatically as it predates the introduction of staticmethod()) which is called to *construct* an instance. This can only be done once for a specific object since each call to __new__ will result in a *new* object. In other words, this is perfect for immutable objects -- once created, never changed. __init__, OTOH, is called on the *instance* to initialize it.

(501, 142, 1), (513, 142, 1), (503, 142, 1)]
and I want to end with a dict like this:
{141: {1: [203, 213, 201], 2: [168, ], 3: [162, ]}, 142: {1: [503, 513, 501],
2: [568, ], 4: [562, ]}}
the logic of the final output:
a) the outer dict's key is a set() of the 2rd value of the input.
b) the inner dict's key is a set() of the 3th value for tuples which 3rd value
equals a).
c) the inner list will be fill up with the 1st value of every tuple which 3rd
value equals b) and its 2rd value equals a).
So far, the only thing it seems I can achieve is the first part:
outer_dict = dict([(x,dict()) for x in set(row[1] for row in lista)])
From then on, I'm starting to get tired after several successful failures (I
tried with itertools, with straight loops ...) and I don't know which can be
the easier way to get that final output.
Thanks in advance.

Re: PyPy 1.0: JIT compilers for free and more
Kay Schluehr wrote: Nice to read that things are going on. I've still a PyPy 0.7 version on my notebook. I guess I will upgrade :) A somewhat unrelated question. With Py3K Python gets optional type annotations. Are you already architecting an annotation handler that can process these annotations? This feature is somewhat competitive to all the complicated type inference and jitting you have been worked out so I don't know how it fits well into the current PyPy architecture? I don't see at all why type annotations are competitive to the type inference that PyPy's translation toolchain is doing. The type inference of PyPy is an artefact of the way we are implementing our interpreter (namely in RPython). You also wouldn't say that the static typing of C is competitive to type annotations because CPython is written in C, right? The JIT (which is completely independent from our type inference engine) will hopefully deal well with the eventual addition of type annotations (it's not clear to me how soon we will start supporting Py3k features, we are not even fully supporting Python 2.5 yet). Since the JIT is automatically generated out of the Python interpreter it should deal with any sort of language changes rather well. Whether that is true in practice remains to be seen, but this is one of the reason why PyPy was started in the first place. Also, I fail to see how type annotations can have a huge speed-advantage versus what our JIT and Psyco are doing. Imagine you have a function that is nicely algorithmic, takes only integers as arguments and only does some calculations with them. If you have a Psyco-like scheme, the JIT will note that you are using it mostly with ints, generate relatively efficient assembly for the whole function (at least after it has been called several times). If you call that functions, the arguments are checked whether they are integers and then the fast assembly code is used without any further type checks. How can you improve on this with type annotations? If the type annotations say that your arguments have to be ints, you _still_ have to check whether this is true. So it is not faster than what Psyco is doing and has the disadvantage that it only works with ints -- good bye, duck typing. Psyco on the other hand will be perfectly happy with you using a custom class that looks mostly like an int and generate assembly optimized for this situation.

One could generate the items in order in less space by doing, for instance, an m-way merge, in which only the lowest member of each of the m sublists is present at any one time.

This is wrong and not answering the question.
Creating a new dict does not change the dict.
He wants to clear *this* dict, and maybe he
cannot know how many other objects are
referring to this dict.
