[ANN]VTD-XML 2.10
VTD-XML 2.10 is now released. It can be downloaded at https://sourceforge.net/projects/vtd-xml/files/vtd-xml/ximpleware_2.10/. This release includes a number of new features and enhancement. * The core API of VTD-XML has been expanded. Users can now perform cut/paste/insert on an empty element. * This release also adds the support of deeper location cache support for parsing and indexing. This feature is useful for application performance tuning for processing various XML documents. * The java version also added support for processing zip and gzip files. Direct processing of httpURL based XML is enhanced. * Extended Java version now support Iso-8859-10~16 encoding. * A full featured C++ port is released. * C version of VTD-XML now make use of thread local storage to achieve thread safety for multi-threaded application. * There are also a number of bugs fixed. Special thanks to Jozef Aerts, John Sillers, Chris Tornau and a number of other users for input and suggestions -- http://mail.python.org/mailman/listinfo/python-list
wxpython:how to minimize to taskbar
I'm kinda newbie to python and wxPython. Now I'm confronting a thorny problem: how can I make my program minimize to the taskbar represented as an ico, and when there is some message from network coming, it will pop out? -- http://mail.python.org/mailman/listinfo/python-list
wxPython unexpected exit
Hi, wxPython is cool and easy to use, But I ran into a problem
recently when I try to write a GUI.
The thing is I want to periodically update the content of StatixText
object, so after create them, I pack them into a list...the problem
comes when I later try to extract them from the list! I don't know
why?
my code is as following:
import wx, socket
import thread
class MyFrame(wx.Frame):
firstrun = 0
def __init__(self):
wx.Frame.__init__(self, None, -1, 'Notifier')
self.panel = wx.Panel(self, -1)
self.length = 50
self.scale = 0.6
self.count = 5
self.size = wx.Frame.GetSize(self)
self.distance = self.size[1] / self.count
self.labellist = []
self.gaugelist = []
def ParseAndDisplay(self, data):
print "Successful access to main Frame class"
print 'And receive data: ', data
if MyFrame.firstrun == 0:
print 'First time run'
items = 3
for i in range(items):
self.labellist.append(wx.StaticText(self.panel,
-1, data+str(i),
(150, 50+i*20), (300,30)))
MyFrame.firstrun = 1
else:
self.labellist[0].SetLabel('AAA')//PROGRAM WILL ABORT
HERE!!!
self.labellist[1].SetLabel("Guo")
self.labellist[2].SetLabel("Qiang")
class NetUdp:
def __init__(self):
self.port = 8081
self.s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
self.s.bind(("", self.port))
print "Listening on port", self.port
def recvdata(self):
data, addr = self.s.recvfrom(1024)
return data
def netThread():
netudp = NetUdp()
while True:
data = netudp.recvdata()
frame.ParseAndDisplay(data)
if __name__ == '__main__':
firstrun = 0
app = wx.PySimpleApp()
frame = MyFrame()
frame.Show()
# start network thread first
id = thread.start_new_thread(netThread, ())
# main wxpython loop begins
app.MainLoop()
I know the code is ugly, but can anyone really save me here!

Thanks!
I also found a thing called 'audacious announcer' which can output
detail information of the playing track.
actually I'm working on a small program to display lyrics while
playing music in media player.

can python do some kernel stuff?
Hi to all python now has grown to a versatile language that can accomplish tasks for many different purposes. However, AFAIK, little is known about its ability of kernel coding.

Yes, many library can permit you to respond to keyboard event, however, what I want is a universal function. as long as a key is pressed, no matter where, my program can repond. I am quite strange with this topic. But according to my understanding, any event, keyboard event for example, once triggered, will be dilivered by keyboard driver to X system, and then any running program can either choose to respond or ignore.

If you are writing program in emacs, of course, the keyboard inputs are meant for emacs only. What I want is no matter what program you're running, keyboard events can be anyway caught by my program.

Distributing multiple packages with on setup.py
Hi, I've reorganized my Python project to be under a same name umbrella. My project can now be seen as multiple subsystems than can depend on each other. That means that every sub-package can now be distributed alone so that only required dependencies can be installed. The old structure: / ├─ myproj/ │ ├─ __init__.py │ ├─ mod1.py │ ├─ subpackage1/ │ └─ subpackage2/ └─ setup.py The new structure: / ├─ myproj/ │ ├─ common/ │ │ └─ mod1.py │ ├─ subpackage1/ │ ├─ subpackage2/ │ └─ __init__.py └─ setup.py As you can see not much has changed except that `myproj` is now a `namespace package <https://packaging.python.org/guides/packaging-namespace-packages/>`_ and that sub-packages ``common``, ``subpackage1`` and ``subpackage2`` can now be distributed independently. Is it possible, still keeping one unique ``setup.py`` file, to create 3 independent packages? * ``myproj.common`` * ``myproj.subpackage1`` * ``myproj.subpackage2`` Also I'd like to specify that when installing ``myproj.subpackage1``, ``myproj.common`` is required or that ``myproj.subpackage2`` will require both ``myproj.common`` and ``myproj.subpackage1``.

I think I will head this direction. And with `setup.cfg
<https://setuptools.readthedocs.io/en/latest/setuptools.html#configuring-setup-using-setup-cfg-files>`_,
it is quite easy to keep the package's metadata in a standard way and
feed this to setup().

about types.new_class and module
Hello,
I'm looking for an explanation where live classes created by
types.new_class() :
py> import types
py> types.new_class('A')
types.A
py> types.A
AttributeError: module 'types' has no attribute 'A'
py> _.__module__
'types'
The new class comes from `types` module without being inside.
That's annoying to me for my use case :
I'm trying to create dataclasses on the fly using make_dataclass (which
uses types.new_class). For new created classes, I have a cache to not
recreate twice the same class.
But I want to be sure not to override an existing class somewhere in the
namespace which is already 'types.MyNewclass'. but how to check it if
it's not in types ?
To be clear :
make_dataclass('Bla', {}) should raise an error if something named
'types.Bla' already exists.
I hope I'm clear enough.

Re: about types.new_class and module
Thank you for the clarification.
I thought everything was bounded to anything.
Shouldn't the name be changed from `types.A` to `unbound.A` to be less
confusing ?
Le 04/03/2019 à 20:31, MRAB a écrit :
'new_class' creates a new class with the given name and returns a
reference to it.
The class doesn't 'live' anywhere.
Although you might /think/ that an object lives in a certain
namespace, it's just that there's a name there that's bound to the
object.
You can, in fact, create 2 classes with the same name.
>>> import types
>>> t1 = types.new_class('A')
>>> t2 = types.new_class('A')
>>> t1 is t2
False

py2exe has a new maintainer
I am taking over the maintenance and support of py2exe from Thomas Heller. As he announced a few weeks ago he is looking to focus on other things. py2exe has been very useful to me over the years and I look forward to keeping it every bit as useful in the future. I plan to make the transition as smooth as possible for users of py2exe. I don't plan to make changes to the license other than adding my name to the list of people not to sue. I will try to be as helpful as Thomas has been in supporting py2exe on the py2exe mailing list and comp.lang.python. The mailing list, the SourceForge project, and the Wiki will continue in their current locations. The web site is moving to http://www.py2exe.org and the old site will forward to the new one so any bookmarks should still work. I will be releasing version 0.6.3 very soon with a few changes Thomas and others have made over the last few weeks. After that my priorities for py2exe will be: - Support - Documentation (which should help familiarize me with the code) - Automated tests (to point out when I haven't familiarized myself enough) - Bug fixes Any help on any of these fronts will be greatly appreciated. After I feel comfortable with things, I hope to work with other projects in the Python packaging community (e.g., cx_Freeze, PyInstaller/McMillan, py2app, setuptools, etc.) to see if we can't find synergies that will make all of them better. I recognize that different packagers are better for different audiences because of licensing, platform, Python versions, and module support among other things. Working together on the common parts (identifying dependencies, customized handling of modules with unique needs, etc.) should make all of the packagers serve their niches better. I'd like to thank Thomas for the great work he's done with py2exe over the years. He's set a very high standard for me to try and maintain.

py2exe 0.6.3 released
py2exe 0.6.3 released = py2exe is a Python distutils extension which converts Python scripts into executable Windows programs, able to run without requiring a Python installation. Console and Windows (GUI) applications, Windows NT services, exe and dll COM servers are supported. Changes in 0.6.3: * First release assembled by py2exe's new maintainer, Jimmy Retzlaff. Code changes in this release are from Thomas Heller and Gordon Scott. * The dll-excludes option is now available on the command line. It was only possible to specify that in the options argument to the setup function before. The dll-excludes option can now be used to filter out dlls like msvcr71.dll or even w9xpopen.exe. * Fix from Gordon Scott: py2exe crashed copying extension modules in packages. Changes in 0.6.2: * Several important bugfixes: - bundled extensions in packages did not work correctly, this made the wxPython single-file sample fail with newer wxPython versions. - occasionally dlls/pyds were loaded twice, with very strange effects. - the source distribution was not complete. - it is now possible to build a debug version of py2exe. Changes in 0.6.1: * py2exe can now bundle binary extensions and dlls into the library-archive or the executable itself. This allows to finally build real single-file executables. The bundled dlls and pyds are loaded at runtime by some special code that emulates the Windows LoadLibrary function - they are never unpacked to the file system. This part of the code is distributed under the MPL 1.1, so this license is now pulled in by py2exe. * By default py2exe now includes the codecs module and the encodings package. * Several other fixes.

Kamilche wrote: > Is there a command you can execute in Python that will open a window on > the desktop, such as 'My Documents'? Kind of like 'system', but for > folder names, not just programs. I'm running on Windows 2000. There are two issues here. The first is how to open a folder and the second is how to resolve "special" folders. Folders are "documents" typically associated with the explorer.exe application. To open a document with its default app (e.g., a folder), use os.startfile which is included in Python. For example: import os os.startfile(r'c:\windows') Folders like My Documents, My Pictures, etc. are special and you need to determine their actual path before you can open them. The pywin32 extensions (https://sourceforge.net/project/showfiles.php?group_id=78018) include a way to get at this: from win32com.shell import shellcon, shell path = shell.SHGetFolderPath(0, shellcon.CSIDL_MYPICTURES, 0, 0) os.startfile(path) Google for CSIDL to find the constants to use for other special folders.

RE: bad generator performance

Aside from the recursion question... You don't really give the complete story so it's hard to tell what exactly is going on. For example, I would assume the recursion is calling the same method (i.e., depthFirstIterator1 or depthFirstIterator2), but then you posted separate timing information for a "recursive helper function" so I'm not so sure. Also there is not much of a hint as to the nature of your data. Below is a test where each of your 2 methods calls itself recursively. To make it work I had to build a data tree - I used the files and folders in my C:\Python23 directory. In my testing (on Python 2.3.4 on Windows XP), the generator version takes about 1/4 of the time that the list version takes. If both versions call the list version of the method recursively (i.e., you're only getting the benefit of the generator at the top level of the recursion), the generator version is still about 20% faster. Timing differences could potentially depend on your data also - things like how deep vs. wide your tree is.

RE: Python 2.4 killing commercial Windows Python development ?
. Again look at the pain of shared JVM use. I think Microsoft is on the right track to addressing DLL hell now by recommending that DLLs be installed in the application folder, not the system folder. That's analogous to using application specific JVMs and things like py2exe or cx_freeze for Python. > To make installation easier, maybe someone could write a > small .exe that could be frozen with scripts or run with installers and > that would detect the presence/absence of the needed Python version and > offer an auto download and install if needed. My users only get access to "approved" sites (nothing else shows up in their DNS). It's hard enough to get my own domain added to the ordained list, much less a long list like python.org, sourceforge.net, effbot.org, etc. All this isn't just for my clients. I have a number of automated processes that I run on my server that are written in Python. When I need a new version of some module for one of those processes, I don't want to spend the time testing it with each of the others to make sure it didn't break anything. So I build single file executables from my Python scripts so they are completely self-contained. When I want to modify a module, then I can test/correct the impact of any new modules at that point since I'll be in the code anyway. Before I started doing this, the version of Python and the various extension modules in use on my server was a couple of years older than the version on my development machine because I almost never upgraded for fear of breaking several processes. Hard drive space is cheap and building exes is easy and I like the benefits. Jimmy p.s. - on the original topic of this thread - I also buy development tools from Microsoft that ensure I have the right to distribute the needed DLLs so it's not a concern in my case. -- http://mail.python.org/mailman/listinfo/python-list

There are a couple of things you can try. First off, if you are using
Python 2.4, then you may be missing msvcr71.dll and/or msvcp71.dll on
the system you are trying to run on (the corresponding file(s) for
Python 2.3 and earlier are extremely common so you aren't nearly as
likely to run into this problem). Look for the line that looks like this
in the NSIS script:
File /r '${py2exe.
And add this line just after it (assuming you installed Python in the
default location):
File 'C:\Python24\msvc*.*'
If you intend to distribute your result, then you can Google this group
for discussions about msvcr71.dll and license requirements for
redistribution - you won't find a definitive answer to the questions
you'll see, but you should be aware of the issues.
If that doesn't solve your problem, the next step to debugging it is to
try running the multi-file version produced by setup.py. If that doesn't
work, some common problems/workarounds can be found on the py2exe wiki.
Obviously the single file version won't work until the multi file
version works.
Chris Liechti has another solution, but the last time I checked it was
only for Python 2.3. It's on his page at:

win32ui.MessageBox returns the ID of the button that was clicked to
dismiss the message box. There are constants in win32con you can use to
compare to that ID. An example:
>>> import win32con
>>> import win32ui
>>> buttonID = win32ui.MessageBox('Hello World')
>>> if buttonID == win32con.IDOK:
... print 'OK pressed'
... else:
... print 'OK not pressed'
...
OK pressed
I clicked OK when the dialog appeared. There are also constants for
IDCANCEL, IDYES, IDNO, etc. which can be useful if you are using other
buttons (e.g., win32ui.MessageBox('Do it?', None, win32con.MB_YESNO)).

The calculation looks like this A = 0.35 T = 0.30 C = 0.25 G = 0.10 and then I basically continually multiply those numbers together. I need to do it like 200,000+ times but that's nuts.

ANN: EasyDialogs for Windows version 46691.0
EasyDialogs for Windows is available at: http://www.averdevelopment.com/python/ EasyDialogs for Windows is a ctypes based emulation of the EasyDialogs module included in the Python distribution for Mac. It attempts to be as compatible as possible. Code using the Mac EasyDialogs module can often be run unchanged on Windows using this module. The module has been tested on Python 2.3 running on Windows NT, 98, XP, and 2003. EasyDialogs is written in pure Python using Thomas Heller's ctypes module to call Windows APIs directly. No Python GUI toolkit is used. This means that relatively small distributions can be made with py2exe (or its equivalents). A simple test of all the dialogs in EasyDialogs bundled up using py2exe results in a distribution that is about 1.25MB. Using py2exe in concert with NSIS as shown here allows the same test to run as a single file executable that is just under 500KB. Requires: Microsoft Windows, Python 2.3 or higher, and ctypes 0.6.3 or higher (ctypes is included with Python 2.5 and higher, so it is not a separate requirement there). License: MIT Change history: Version 46691.0 - Fixed a bug that caused warnings with newer version of ctypes (including the version included in Python 2.5) - The edit box in AskString now scrolls horizontally if the entered text does not otherwise fit - AskFileForOpen(multiple=True) will allow multiple files to be selected and a list of strings will be returned. If multiple is False (the default if not specified) then only a single file can be selected and a string is returned. This no longer seems to work on the Mac, but it's useful enough to add it to the Windows version anyway. This change is based on a patch contributed by Waldemar Osuch. - Made minor changes to bring inline with SVN revision 46691 for Mac Version 1.16.0 - Removed resource DLL, resources are now in a Python source file which simplifies distribution of apps with py2exe - Spelling corrections - File open/save dialogs did not display on Windows 98 - AskString edit boxes were too short on Windows 98 - Improved display of drop down lists on Windows 98 and NT - Made minor changes to bring inline with CVS version 1.16 for Mac Version 1.14.0 - Initial public release Jimmy -- http://mail.python.org/mailman/listinfo/python-list

py2exe 0.6.9 released
=
py2exe is a Python distutils extension which converts Python scripts
into executable Windows programs, able to run without requiring a
Python installation. Console and Windows (GUI) applications, Windows
NT services, exe and dll COM servers are supported.
Changes in 0.6.9:
* Binaries for Python 2.6 and Python 2.7.
* Fixed a modulefinder crash on certain relative imports.
* Changed the py2exe\samples\singlefile\gui\test_wx.py sample to
use the wx package instead of the old wxPython package.
* Copy the manifest, if any, from the 'template' into the targets
to ensure embedded assembly references, as required for python 2.6
based apps, are copied.
* Allow each target to specify Vista User Access Control flags. For
example, specifying 'uac_execution_info="requireAdministrator"' would
force elevation for the final executable.
Changes in 0.6.8:
* Support for relative imports.
* Fix MemoryLoadLibrary to handle loading function addresses by ordinal
numbers. Patch and test by Matthias Miller.
* Using the options compressed=1, bundle_files=3, and zipfile=None at
the same time now works; patch from Alexey Borzenkov.
* Allow renaming of single-executable files; patch from Alexey
Borzenkov.
* Embedding icon resources into the image now works correctly even for
ico files containing multiple images.
* pyd files from different packages with the same filename no longer
conflict. Patch from Grant Edwards.
* There are new samples for the 'typelibs' support, including the new
option of pre-generating a typelib and specifying the file as an
input to py2exe.
* The test suite is now included in the source distribution.
Changes in 0.6.6:
* Better support for Python 2.5.
* Experimental support for 64-bit builds of Python on win64.
* Better ISAPI support.
* New samples for ISAPI and COM servers.
* Support for new "command-line styles" when building Windows services.
Changes in 0.6.5:
* Fixed modulefinder / mf related bugs introduced in 0.6.4. This
will be most evident when working with things like
win32com.shell and xml.xpath.
* Files no longer keep read-only attributes when they are copied
as this was causing problems with the copying of some MS DLLs.
Changes in 0.6.4:
* New skip-archive option which copies the Python bytecode files
directly into the dist directory and subdirectories - no
archive is used.
* An experimental new custom-boot-script option which allows a
boot script to be specified (e.g., --custom-boot-script=cbs.py)
which can do things like installing a customized stdout
blackhole. See py2exe's boot_common.py for examples of what can
be done. The custom boot script is executed during startup of
the executable immediately after boot_common.py is executed.
* Thomas Heller's performance improvements for finding needed
modules.
* Mark Hammond's fix for thread-state errors when a py2exe
created executable tries to use a py2exe created COM DLL.
Changes in 0.6.3:
* First release assembled by py2exe's new maintainer, Jimmy
Retzlaff. Code changes in this release are from Thomas Heller
and Gordon Scott.
* The dll-excludes option is now available on the command line.
It was only possible to specify that in the options argument to
the setup function before.
The dll-excludes option can now be used to filter out dlls like
msvcr71.dll or even w9xpopen.exe.
* Fix from Gordon Scott: py2exe crashed copying extension modules
in packages.
Changes in 0.6.2:
* Several important bugfixes:
- bundled extensions in packages did not work correctly, this
made the wxPython single-file sample fail with newer wxPython
versions.
- occasionally dlls/pyds were loaded twice, with very strange
effects.
- the source distribution was not complete.
- it is now possible to build a debug version of py2exe.
Changes in 0.6.1:
* py2exe can now bundle binary extensions and dlls into the
library-archive or the executable itself. This allows to
finally build real single-file executables.
The bundled dlls and pyds are loaded at runtime by some special
code that emulates the Windows LoadLibrary function - they are
never unpacked to the file system.
This part of the code is distributed under the MPL 1.1, so this
license is now pulled in by py2exe.
* By default py2exe now includes the codecs module and the
encodings package.
* Several other fixes.

Best practise for dual stack programming in python
Hello, The organisation that I currently work for has a large number of 'legacy' tools and scripts which rely entirely on IPv4. Many of them have been written and not documented etc. The organisation is in the process of moving to a dual stack environment over the next 3 months. With that in mind many of our scripts need to be rewritten and documented. I have been looking at moving from a mix of languages over to a standard which at this point is looking like it will be Python (because I am most familiar with it). I have never done any dual stack coding so I am interested to know if there are any good resources for developing dual stack python code? I have had a look around and have found very little on the python web page which makes me worry. Does anyone have any recommendations on web pages to read or books to look at? Any additional advice would be really appreciated. Regards, Jimmy Stewpot. -- http://mail.python.org/mailman/listinfo/python-list

I can't think of an easy way to achieve the first approach - I've always taken the second approach. The advanced example included with py2exe has an example of how to do this. Look at all the occurrences of test_wx in the following link to see all the pieces involved: http://py2exe.svn.sourceforge.net/viewvc/py2exe/trunk/py2exe/py2exe/samples/advanced/setup.py?view=markup This uses an alternate form of the "windows" and "console" arguments where each target is an object with specially named member variables rather than a string that names the .py file (this string is one of the member variables). This is necessary so you can give different names to the console version and the windows version. Jimmy -- http://mail.python.org/mailman/listinfo/python-list

Crypto Suggestion/Help
Hi all, I need some advise on doing the following. I have a Linux application that allows users to access it via a code (password). At the end of the day, I gather a log of activities of the users and zip the file and would like to encrypt it so that the users can not access it or tamper with it. Only manager should. If I use a private/public key for doing so I have to store the private key on my computer. What is a good way to encrypt a file and have the key well hidden on the same computer? If you have any other way to do, like MD5 or similar, please let me know. Thanks, Jimmy -- http://mail.python.org/mailman/listinfo/python-list
Re: Crypto Suggestion/Help
Paul, Thanks for the reply. Yes the shop has only one machine and many users use it to perform transactions. Maybe a basic Linux/Unix permissions will do as Thomas Kruger suggested in the thread following you. --Jimmy Paul Rubin wrote: > Jimmy E Touma <[EMAIL PROTECTED]> writes: >> I need some advise on doing the following.
