Twisted 11.1.0 Released
On behalf of Twisted Matrix Laboratories, I am pleased to announce the release of Twisted 11.1. Highlights of the 185 tickets closed include: * The poll reactor as default where applicable, instead of select everywhere. * A new SSL implementation only relying on OpenSSL for cryptography, (not I/O) making it more robust. * Several improvements to the fresh HTTP/1.1 client implementation, including proxy and cookie support. * My personal favorite: a new howto has been published on test-driven development with Twisted. * A special mention to the new abortConnection support on TCP and SSL connections, heroically pushed by Itamar and Jean-Paul, and the oldest ticket closed by this release. This is the last release supporting Python 2.4 (the support on Windows stopped with 11.0). For more information, see the NEWS file here: http://twistedmatrix.com/Releases/Twisted/11.1/NEWS.txt Download it now from: http://pypi.python.org/packages/source/T/Twisted/Twisted-11.1.0.tar.bz2 or http://pypi.python.org/packages/2.5/T/Twisted/Twisted-11.1.0.win32-py2.5.msi or http://pypi.python.org/packages/2.6/T/Twisted/Twisted-11.1.0.win32-py2.6.msi or http://pypi.python.org/packages/2.7/T/Twisted/Twisted-11.1.0.win32-py2.7.msi Thanks to the supporters of the Twisted Software Foundation and to the many contributors for this release. -- Thomas -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/

Why sock.bind is always report 10048 error when in a script with multiprocessing

Uli Thanks for reply, I'll try to elaborate a bit :) I should have included this bit from: http://docs.python.org/library/ctypes.html#loading-shared-libraries All these classes can be instantiated by calling them with at least one argument, the pathname of the shared library. If you have an existing handle to an already loaded shared library, it can be passed as the handle named parameter, otherwise the underlying platforms dlopen or LoadLibrary function is used to load the library into the process, and to get a handle to it. So, I've got this handle to my .dll and would want to get that passed as an argument when firing up .py via ShellExecute and use one of the dll load functions that take in handle. What I don't know if these windows/python dll handles are interchangable at all. Think it would be quite nice if they were. But if they aren't I need to forget about it and just #include Python.h -- http://mail.python.org/mailman/listinfo/python-list

Re: Passing DLL handle as an argument (in Windows)
Hmm. Let me describe what is going a bit more carefully: What I build is a dll file that has exported function that gets called when the host application/dll loads my dll. In this function the function pointers to the actual SDK functions are fetched. After this my dll's registers some plugins that have callbacks. After that it's all about reacting to an event/callback. What I'd like to do is that after fetching those SDK function pointers I'd like to fire up .py/.pyc that snoops for possible plugins written in python and registers those plugins and callbacks and let them react to events. Obviously this python code needs access to those SDK functions. Essentially it would show for the host app as one .dll but registers multiple plugins from different python files. I don't mind if it's not ShellExecute route, but I'd prefer approaching this so that I don't need to compile different dll's to different versions of python but let the python code take care of that stuff. -- http://mail.python.org/mailman/listinfo/python-list

Okay, so you want to export functions from your host application (it
doesn't matter if that is inside a DLL or not) to a bunch of Python
plugins. This is actually the embedding that I hinted at and documented,
but here's some example code (stripped of any error handling and
reference counting, so beware!):
// append line to debug log
static PyObject*
log_string(PyObject *self, PyObject *args)
{
char const* arg = 0;
if(!PyArg_ParseTuple(args, s, arg))
return NULL;
fprintf(debug_output, %s, arg);
Py_RETURN_NONE;
}
// exported API
static PyMethodDef host_api[] =
{
{log_string, log_string, METH_VARARGS,
log_string(string) - None\n
Write text to debug output.},
{NULL, NULL, 0, NULL}
};
Py_Initialize();
PyObject* host_api_module = Py_InitModule(host, host_api);
PyObject* test_module = PyImport_ImportModule(./test.py);
PyObject* main_function = PyObject_GetAttrString(test_module, main);
PyObject* res = PyObject_CallObject(main_function, NULL);
Py_Finalize();
This has the disadvantage that it blocks, for multiple Python threads,
you need to program a dispatcher. Also, you can only have a single
interpreter loaded, so other parts of your program may not call
Py_Initialize().
It does the job for my uses, so I hope it helps!

Dynamically Generate Methods
Hi, I have a class Record and a list key_attrs that specifies the names of all attributes that correspond to a primary key. I can write a function like this to get the primary key: def get_key(instance_of_record): return tuple(instance_of_record.__dict__[k] for k in key_attrs) However, since key_attrs are determined at the beginning of the program while get_key() will be called over and over again, I am wondering if there is a way to dynamically generate a get_ley method with the key attributes expanded to avoid the list comprehension/ generator. For example, if key_attrs=['A','B'], I want the generated function to be equivalent to the following: def get_key(instance_of_record): return (instance_of_record['A'],instance_of_record['B'] ) I realize I can use eval or exec to do this. But is there any other way to do this? Thanks, gz -- http://mail.python.org/mailman/listinfo/python-list

Fine... so open a directory window, follow Tools/Folder Options/File Types Scroll down to PYW, click [Advanced] You should get an Edit File Type dialog. Mine shows just one action open, yours probably has open and edit. Select edit and then click [Edit] button. See what it says for the application to be used. Do the same on the Win7 machine -- it probably doesn't have edit as an action, so you'll be picking the [New] button. Define the new action to look like the action on the laptop (use the correct path to the python executable, and maybe to IDLE). Heck, check what those actions show for PY files too... The only difference between PY and PYW should be the application used in the open action. PY = .../python.exe PYW = .../pythonw.exe Also make sure that the open action is the defined default (select the action, and click the default button); when there are more than one action, the default will be in bold. My guess is that Win 7 is behind this. If so, it's good-bye Python. Comments? See my response to Neil Cerutti a few msgs above this one. -- http://mail.python.org/mailman/listinfo/python-list

[issue13386] Document documentation conventions for optional args
Ezio Melotti ezio.melo...@gmail.com added the comment:
From Ezio's original post: '''
If a function has optional arguments but it doesn't accept keyword
arguments, the func([arg1]) notation is used instead. ... The
notation func([arg=default]) should never be used, and func([arg])
should be used only when keyword args are not accepted.
'''
In the following, I give objections to this PO (position only) rule and
suggest an alternative ND (no default) rule: use 'name=default' when
there is a default and '[name]' when there is not'.
Maybe we should try to keep it simple and just document the signature of the
function.
Everything that can not be described in the signature can be explained by words.
I tried to write down all the combinations of optional/non optional,
with/without default, works/doesn't work with keywords to see how to represent
them, but it started being a bit messy. The problematic combinations (for
example a function that accepts an optional arguments with no default but that
doesn't work with keywords) seem quite rare, and for them we could just write
down what's special about them.
There are two more cases that could be solved with a specific notation though:
1) optional arg, with default, doesn't work with keywords (e.g. range,
startswith):
func(arg1)
func(arg1, arg2)
*arg2* defaults to default.
2) optional arg, with no default, that works only with keywords:
func(arg1, *, arg2)
The keyword-only *, and the multiple signatures tricks can also be used for
other similar cases.
func(arg1, **kwargs) can be used for functions that accept kwargs without
expecting any specific value; if the values are known and have defaults they
could be included in the signature (even if the default is like foo =
kwargs.get('foo', default)).
This should cover most of the cases, it only uses valid Python syntax and
avoids potentially confusing [].

Here both the text nodes are printed on a newline and they are indented.
With your patch it should be:

I'm not sure there's any reason to prefer the second option though.

Nick Coghlan ncogh...@gmail.com added the comment: Please don't stress too much about providing an indication that the repr has been truncated - it's an error message, not part of the normal program output. Besides, the lack of a closing ')', ']', '}' or '' will usually indicate something is amiss in long reprs. More useful would be to raise a separate feature request about the lack of width and precision handling for string formatting in PyUnicode_FromFormatV - the common format code handling means it *accepts* the width and precision information for string codes, but then proceeds to completely ignore it. It should be using them to pad short strings (width) and truncate long ones (precision), just like printf() (only in terms of code points rather than bytes, since those codes work with Unicode text). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13349 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue13349] Uninformal error message in index() and remove() functions
Petri Lehtinen pe...@digip.org added the comment: Nick Coghlan wrote: Please don't stress too much about providing an indication that the repr has been truncated - it's an error message, not part of the normal program output. Besides, the lack of a closing ')', ']', '}' or '' will usually indicate something is amiss in long reprs. Ok. This makes things easier. More useful would be to raise a separate feature request about the lack of width and precision handling for string formatting in PyUnicode_FromFormatV - the common format code handling means it *accepts* the width and precision information for string codes, but then proceeds to completely ignore it. It should be using them to pad short strings (width) and truncate long ones (precision), just like printf() (only in terms of code points rather than bytes, since those codes work with Unicode text).

I am currently altering my distutils package to add a function called nt_quote_dir that adds quotes to paths with spaces and then applies it to each path if the platform is win32. You shouldn’t have to do that; there’s already a similar function in distutils.spawn. When I'm done I will submit a diff after confirming that it works. What is needed is a diff for distutils 2.7 or 3.2 adding a test with a file containing a space.

[issue13294] http.server: HEAD request should not return a body
Michele Orrù maker...@gmail.com added the comment:
These tests shows how SimpleHTTPRequestHandler behaves: if the class
contains a do_FOO method, it is called, otherwise error501 is raised.
That's what Karl said with «Or to modify the library code that for any
resources not yet defined.».
Since SimpleHTTPRequestHandler.do_HEAD exists, and this is reflected
in the correspondent unittest, I belive that this is not a bug.
Patch attached. No problem if it's not committed now. I hope that
someone in the noisy list will make a little cleanup one day :)

[issue13420] newer() function in dep_util.py discard changes in the same second
Éric Araujo mer...@netwok.org added the comment: Hi David. Thanks for reporting the issue. I have to warn you that there is a high bar for distutils changes; due to the mass of code out there that relies on undocumented internal behavior or works around old bugs, a feature freeze is in effect and we try to be very careful with the changes we make to fix bugs. Some things clearly qualify as bugs and can be fixed, some things are clearly new features and are redirected to the distutils2 project, some bugs can’t be fixed because everyone and every tool is used to the buggy behavior. Here we are in a gray area between bug and feature; one can argue that the behavior is not what is expected (bug), but one can reply that the documentation just doesn’t say that filesystems with millisecond precision are supported (so it would be a new feature). For example, I've a file that is modified with an installation prefix. Modified by what when? CDBS runs the build step and after the install step. In build step, the prefix is '/usr/local' because the prefix argument isn't supported, immediately the install step runs with prefix='/usr', so the file that contains a variable with project path modified with the prefix is not copied by distutils, it runs in a different millisec but in the same second. I don’t understand when the file is changed. (BTW, I read some Debian mailing lists and I had the impression that CDBS was deprecated.) -- nosy: +jsjgruber ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13420 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
