Overriding Thread.join in derived class.
If one creates a thread using threading.Thread and makes it a daemon by calling setDaemon(), then when Python is exiting it will not attempt to call join() on that thread and wait for it to complete first. The problem with this is that the daemonised thread will continue to run while atexit register callbacks are being called and while Python is being subsequently destroyed The result is that the daemonised thread may access application components that have been cleaned up and in the worst case as Python progresses with destroying interpreters it could try accessing things like sys.modules which may no longer exist. End result is that it could result in a Python exception at some point, evidenced by messages starting with: Exception in thread Thread-1 (most likely raised during interpreter shutdown) or: Unhandled exception in thread started by bound method Thread.__bootstrap of Thread(Thread-1, started daemon) In order to avoid this, do people think that as an alternative to creating daemonised thread that it would be reasonable to create a derived Thread class for the particular task which overrides Thread.join() method to set some flag or otherwise take some action that the thread would notice to tell it to stop, and then call base class Thread.join(). This way you can flag the thread to shutdown automatically when Python is going around calling join() on non daemonised threads. Or am I missing the obvious as far as ways of flagging threads to tell them to stop? Note that this is where Python is being used embedded in a C program. There is no Python main function where code can be put to signal threads to otherwise stop. Graham -- http://mail.python.org/mailman/listinfo/python-list

Unless you have an interoperability requirement or some other specific issue, you should stick with AES and the SHA2 family.

This is especially the case for business applications in the US, since AES and SHA are US federal standards and if you use them and something goes wrong with them, you can at least say you followed the standard.

passing arguments with ampersands
hey, i have a win32 gui application that accepts filenames as arguments (either via command line or via associating an extension to the application) which are then opened in it. the problem is that as soon as the filename contains characters like '', the process fails at the very beginning (sys.argv). for example when the full path of the file im trying to open like this is Quote:D:\ftp\Music\Mixes Compilations\Above Beyond - Essential Mix\001_Essential_Mix_2004-06-06_-_Above_and_Beyond.txt when i put 'print sys.argv[1:]' at the very beginning of the script, all i get is this: Quote:['D:\\ftp\\Music\\Mixes'] i already have a piece of code that puts together paths with spaces sent via arguments, but this '' drives me crazy. other than that, after i close the application (which actually starts without any errors), the commands line gets filled with a message like this: Quote:The system cannot find the path specified.

Paul McGuire [EMAIL PROTECTED] wrote: Carl Banks' post using defaultdict is the correct solution. The raison d'etre for defaultdict, and the reason that it is the solution to the OP's question, is that instead of creating a just-in-case default value every time, the defaultdict itself is constructed with a factory method of some kind (in practice, it appears that this factory method is usually the list or dict class constructor). If a reference to the defaultdict gives a not-yet-existing key, then the factory method is called to construct the new value, that value is stored in the dict with the given key, and the value is passed back to the caller. No instances are created unless they are truly required for initializing an entry for a never-before-seen key.

Re: passing arguments with ampersands
theres no special portion of code, just the one that handles filenames with spaces. the problem is that when i associate a file extension to my application and i open it, the filename is not quoted before passed as an arguement. i dont know if its the problem of windows or something, or it was just my fault when i incorrectly associated the extension. anyway, this is the code that outputs the second quote i posted in the original message: args = None if len(sys.argv) 1: args = sys.argv[1:] print args and this is the code that handles the filenames with spaces (as space generally delimits cmdline params). its not very ellegant, needs a bit of tuning, but it works (i dont use any kind of -d --something params yet). [code] newargs = [] if args: first = None for arg in args: if not first: first = arg continue if os.path.isfile(first): newargs.append(first) first = None continue if arg.find(:) == -1: first = .join([first, arg]) if first: newargs.append(first) [/code] how can i make the params get quoted before send as arguments? thanks in advance. 2007/8/18, O.R.Senthil Kumaran [EMAIL PROTECTED]: Quote:D:\ftp\Music\Mixes Compilations\Above Beyond - Essential Mix\001_Essential_Mix_2004-06-06_-_Above_and_Beyond.txt when i put 'print sys.argv[1:]' at the very beginning of the script, all i get is this: Quote:['D:\\ftp\\Music\\Mixes'] Can you share the portion of the code?

for k in data:
if k in data1:
result.append(k)
print result
fh.close()
can you tell me problem with my script and what should is do for this
For a start, you are iterating k in data *everytime* you iterate a
line in fh which will give you a speed issue and give you duplicates
in the result. The following is probably what you intended to do
for line in fh.readlines():
do stuff
for k in data:
do stuff
.split() splits by spaces, newlines AND tabs so you just need
splitted = line.split()
eg
ln = 'fhl1\tfkh2\r\n'
ln.split()
['fhl1', 'fkh2']
I think I would have done something like this (not tested)
Input = open('sheet1').read().split()
data = set(Input[::2])
data1 = set (Input[1::2])
result = data.intersection(data1)
or even this (if you don't need data and data1 later in the code)
Input = open('sheet1').read().split()
result = set(Input[::2]).intersection(set (Input[1::2]))

Re: clarification

Right now, sets don't support the 'add' and 'multiply' operators, so 'sum' and (the currently ficticious) 'product' won't work at all; while 'any' and 'all' don't work as one might hope. Are there an 'intersection' and 'union' built-ins anywhere? For intersection and union of a sequence of sets, I'd use: def union_all(sos): result = set() for s in sos: result.update(s) return result def intersect_all(sos): it = iter(sos) result = set(it.next()) for s in it: result.intersection_update(s) return result The latter will raise an exception if sos is empty -- I don't think the intersection of no sets at all has a single natural interpretation (while the union of no sets at all appears to be naturally interpreted as an empty set)... if you disagree, just wrap a try/except around the initialization of result, and return whatever in the except clause. Of course, hoisting the unbound method out of the loops can afford the usual small optimization. But my point is that, in Python, these operations (like, say, the concatenation of a sequence of lists, etc) are best performed in place via loops calling mutator methods such as update and intersection_update (or a list's extend, etc), rather than functionally (building and tossing away many intermediate results). E.g., consider: brain:~ alex$ python -mtimeit -s'sos=[set(range(x,x+4)) for x in range(0, 100, 3)]' 'r=set()' 'for x in sos: r.update(x)' 10 loops, best of 3: 18.8 usec per loop brain:~ alex$ python -mtimeit -s'sos=[set(range(x,x+4)) for x in range(0, 100, 3)]' 'r=reduce(set.union, sos, set())' 1 loops, best of 3: 87.2 usec per loop Even in a case as tiny as this one, reduce is taking over 4 times longer than the loop with the in-place mutator -- and it only gets worse, as we're talking about O(N squared) vs O(N) performance! Indeed, this is part of what makes reduce an attractive nuisance...;-). [[And so is sum, if used OTHERWISE than for the documented purpose, computing the sum of a sequence of numbers: a loop with r.extend is similarly faster, to concatenate a sequence of lists, when compared to sum(sol, [])...!!!]] Alex -- http://mail.python.org/mailman/listinfo/python-list

Re: Canceling events on COM Objects in python
Mike,
Thank you for the suggestion. I will ask over there also. The event is
sent back from the COM interface as the code illustrates.
MakeActiveXClass allows me to pass the object that will receive events.
I don't understand much more detail about how it works. It is
certainly a different model than the standard wx event system...

sort dictionary by specific values
Hi,

I want to sort the entire dictionary based on the last values in each line.
First for [-1][0] and then[-1][0].
So sorted descending I would like the output to look like:
Code: ( text )
1. d
2. {8: (99, 99), 4: [(45, 78), (56, 78), (99, 78)], 9: [(55, 67), (77,

I can't make any sense of your requirements or your example, but perhaps
I can help somewhat.
You CANNOT sort a (standard Python) dictionary. You CAN find some
alternative implements of dictionaries on the web that allow ordering,
and you CAN extract the key,value pairs from a dictionary into a list,
and sort that list (by any criteria you want).

Each line means each value in the dictionary?
Did you mean ordering [-1][0] and then [-1][1]?
Dictionaries cannot be ordered, but you can work with its items (as a list).
Your data is not homogeneous (values in the dictionary are both tuples
and list of tuples). If you can build it that way:
d = {8: [(99, 99)], 9: [(55, 67), (77, 66), (67, 88)], 4: [(45, 78),
(56, 78), (99, 78)], 5: [(67, 77)]
It would be easy to sort:
import operator
cmplast = lambda x, y: cmp(x[-1], y[-1])
sorted(d.items(), key=operator.itemgetter(1), cmp=cmplast, reverse=True)
or
cmplast1 = lambda x, y: cmp(x[1][-1], y[1][-1])
sorted(d.items(), cmp=cmplast1, reverse=True)
[(8, [(99, 99)]), (4, [(45, 78), (56, 78), (99, 78)]), (9, [(55, 67),

[Announce] PyGooCanvas 0.9.0
I am pleased to announce version 0.9.0 of the Python bindings for Goocanvas. It is available at: https://developer.berlios.de/projects/pygoocanvas/ The bindings are updated with the new Goocanvas API PyGooCanvas 0.9.0 (Aug 18 2007) = o Wrap goo_canvas_item_get_bounds (Gian Mario) o fix compilation on Solaris, patch by JerryYu [EMAIL PROTECTED]. Fixes LP#130106 (Gian Mario) o Add goocanvas.ItemSimple.get_line_width (Gian Mario) o Docs updated fixes LP#124921 (Gian Mario) Blurb: == Goocanvas [1] is a canvas widget for GTK+, It is similar in many ways to FooCanvas, hence the name, but it uses cairo for rendering, it has an optional model/view split, and uses interfaces for items views (so you can easily turn any application object into a canvas item or view). PyGooCanvas is a wrapper which exposes the goocanvas API to the python world. It is fairly complete; most of the API are covered. The documentation is done, anyway bug reports on docs are really important to improve the documentation. Like the GTK+ library, PyGTK and GooCanvas itself PyGooCanvas is licensed under the GNU LGPL, so is suitable for use in both free software and proprietary applications. PyGooCanvas requires: = o Goocanvas = 0.9.0 o PyGObject = 2.10.1 (2.11.3 to build the docs) o PyGTK = 2.10.4 o PyCairo = 1.2.0 Bug reports should go to https://launchpad.net/pygoocanvas/ [1] http://sourceforge.net/projects/goocanvas cheers -- Gian Mario Tagliaretti -- http://mail.python.org/mailman/listinfo/python-list

PEP 11 update - Call for port maintainers to step forward
I made a quick update to PEP 11, Removing support for little used platforms. I added details about ending support for AtheOS/Syllable and BeOS. I also added a yet-to-be-fleshed out section entitled Platform Maintainers. I intend that to the extent possible we document the responsible parties for various platforms. Obviously, common platforms like Windows, Mac OS X, Linux and common Unix platforms (Solaris, *BSD, what else?) will continue to be supported by the core Python developer community, but lesser platforms should have one or more champions, and we should be able to get ahold of them to determine their continued interest in supporting Python on their platform(s). If you are the owner of a minor platform, please drop me a note. Ones I'm aware of that probably need specialized support outside the core Python developers include: IRIX Tru64 (aka OSF/1 and other names (what else?)) OS2/EMX (Andrew MacIntyre?) Cygwin MinGW HP-UX AIX Solaris version 8 SCO Unixware IRIX and Tru64 are likely to go the way of the dodo if someone doesn't step up soon to offer support. I don't expect the others to disappear soon, but they tend to need more specialized support, especially in more challenging areas (shared library support, threading, etc). If you maintain the platform-specific aspects for any of these platforms, please let me know. If you aren't that person but know who is, please pass this note along to them. If I've missed any other platforms (I know I must have have missed something), let me know that as well.

ANN: UliPad 3.7 released!
UliPad is a flexible editor, based on wxPython. It's has many features,just
like:class browser, code auto-complete, html viewer, directory browser, wizard,
etc. The main feature is the usage of mixin. This makes UliPad can be
extended easily. So you can write your own mixin or plugin, or simple script,
these can be easy and seamless integrated with UliPad.
What's new in 3.7
===
New Features and Changes:
#. Add PEP8 sytle checking
#. Enhance calltip showing
#. Add a new option in Preference, which is used for when you toggle comment
lines(Ctrl+/ or Ctrl+\) if it'll popup a comment dialog. You can find it in
Preference-Document-Show comment character dialog when adding comment.
#. Saving auto todo window status
#. Changing shortcut of quote dialog from Ctrl+Q to Ctrl+'
#. Changing the number of recent files to 20
#. Changing shortcut Ctrl+Alt+L to Alt+Z, Ctrl+Alt+B to Alt+X
#. Saving the status of Message window word wrap
#. Saving the snippets window position
#. The results of find in files can only show the filenames and you can copy
them to clipboard
#. Add Spanish language translation and Traditional Chinese language translation
#. Using ZestyParser Module to parse the source code syntax
#. Improving input assistant functionality
#. Adding config.txt documentation
#. When saving files, automatically adding accordingly filename suffix
#. Adding mixin reload mechanism, it will be very useful when developing
#. Adding folder sort functionality when adding new folder to directory browser
window
#. Adding template in input assistant, and you can press TAB key to jump to the
next field. The template just like: ${1:something}.
#. Adding LUA syntax support
#. Adding mako(template module) support plugin
#. Adding batch filenames rename plugin
#. Enable ftp window be openned left or bottom pane according to the openning
position
#. Adding Alt+R shortcut for open recently files

Re: Parser Generator?
Thanks for all the replies! SPARK looks promising. Its doc doesn't say if it handles unicode (CJK in particular) encoding though. Yapps also looks powerful: http://theory.stanford.edu/~amitp/yapps/ There's also PyGgy http://lava.net/~newsham/pyggy/ I may also give Antlr a try.

Summary: memoryview('test') is causing a segfault
Initial Comment:
./python -c memoryview('test')
Segmentation fault
I compiled Python 3.0 with
$ ./configure --with-pydebug --enable-unicode=ucs4
and
$ make EXTRA_CFLAGS=-DPy_REF_DEBUG -DPy_TRACE_REFS -DPy_DEBUG
after a make clean; rm -rf build; svn up
I've used gdb to trace the segfault:
Program received signal SIGSEGV, Segmentation fault.

Kaiser (kbk) Summary: Display CallTips for classes using metaclasses. Initial Comment: Hello, Currently, if you write something like this: class MyType(type): pass class MyClass(object): __metaclass__ = MyType def __init__(self, a): pass And write in the shell: MyClass( a calltip won't be displayed. To fix this, replace this line in CallTups.py: if type(ob) in (types.ClassType, types.TypeType): with this one: if issubclass(type(ob), (types.ClassType, types.TypeType)): and now it works. Thanks, Noam -- You can respond by visiting: https://sourceforge.net/tracker/?func=detailatid=105470aid=1775388group_id=5470 ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Committed revision 57193. This problem was due to not initializing the
new BufferError properly. Travis mentioned this in his post to
python-3000.
