Hope someone can tell me before a holy war erupts :-) Only the holy war can give an answer here. It certainly has *nothing* to do with Python; Python calls the operating system functions to read from the network and write to the disk almost directly. So it must be the operating system itself that slows it down. To investigate further, you might drop the write operating, and measure only source.read(). If that is slower, then, for some reason, the network speed is bad on Windows. Maybe you have the network interfaces misconfigured? Maybe you are using wireless on Windows, but cable on Linux? Maybe you have some network filtering software running on Windows? Maybe it's just that Windows sucks?-) If the network read speed is fine, but writing slows down, I ask the same questions. Perhaps you have some virus scanner installed that filters all write operations? Maybe Windows sucks? Regards, Martin Thanks for the ideas, Martin. I ran a couple of experiments to find the culprit, by downloading the same 20 MB file from the same fast server. I compared: 1. DL to HD vs USB iPod. 2. AV on-access protection on vs. off 3. source. read() only vs. file.write( source.read() ) The culprit is definitely the write speed on the iPod. That is, everything runs plenty fast (~1 MB/s down) as long as I'm not writing directly to the iPod. This is kind of odd, because if I copy the file over from the HD to the iPod using windows (drag-n-drop), it takes about a second or two, so about 10 MB/s. So the problem is definitely partially Windows, but it also seems that Python's file.write() function is not without blame. It's the combination of Windows, iPod and Python's data stream that is slowing me down. I'm not really sure what I can do about this. I'll experiment a little more and see if there's any way around this bottleneck. If anyone has run into a problem like this, I'd love to hear about it... You could try copying the file to the iPod using the command line, or copying data from disk to iPod in, say, C, anything but Python. This would allow you to identify whether Python itself has anything to do with it. Well, I think I've partially identified the problem. target.write( source.read() ) runs perfectly fast, copies 20 megs in about a second, from HD to iPod. However, if I run the same code in a while loop, using a certain block size, say target.write( source.read(4096) ), it takes forever (or at least I'm still timing it while I write this post). The mismatch seems to be between urllib2's block size and the write speed of the iPod, I might try to tweak this a little in the code and see if it has any effect. Oh, there we go: 20 megs in 135.8 seconds. Yeah... I might want to try to improve that... After some tweaking of the block size, I managed to get the DL speed up to about 900 Mb/s. It's still not quite Ubuntu, but it's a good order of magnitude better. The new DL code is pretty much this: blocksize = 2 ** 16# plus or minus a power of 2 source = urllib2.urlopen( 'url://string' ) target = open( pathname, 'wb') fullsize = float( source.info()['Content-Length'] ) DLd = 0 while DLd fullsize: DLd = DLd + blocksize # optional: write some DL progress info # somewhere, e.g. stdout target.close() source.close() I'd like to suggest that the block size you add to 'DLd' be the actual size of the returned block, just in case the read() doesn't return all you asked for (it might not be guaranteed, and the chances are that the final block will be shorter, unless 'fullsize' happens to be a multiple of 'blocksize'). If less is returned by read() then the while-loop might finish before all the data has been downloaded, and if you just add 'blocksize' each time it might end up 'fullsize', ie apparently 100% downloaded! Interesting. I'll if to see if any of the downloaded files end prematurely :) btw, I forgot the most important line of the code! blocksize = 2 ** 16# plus or minus a power of 2 source = urllib2.urlopen( 'url://string' ) target = open( pathname, 'wb') fullsize = float( source.info()['Content-Length'] ) DLd = 0 while DLd fullsize: # +++ target.write( source.read( blocksize ) ) # +++ # +++ DLd = DLd + blocksize # optional: write some DL progress info # somewhere, e.g. stdout target.close() source.close() Using that, I'm not quite sure where I can grab onto the value of how much was actually read from the block. I suppose I could use an intermediate variable, read the data into it, measure the size, and then write it to the file stream, but I'm not sure it would be worth the overhead. Or is there some other magic I should know about? If I start to get that problem, at least

Trouble with regular expressions
Hi, I'm quite new to regular expressions, and I wonder if anyone here could help me out. I'm looking to split strings that ideally look like this: Update: New item (Household) into a group. This expression works ok: '^(Update:)?(.*)(\(.*\))$' - it returns (Update, New item, (Household)) Some strings will look like this however: Update: New item (item) (Household). The expression above still does its job, as it returns (Update, New item (item), (Household)). It does not work however when there is no text in parentheses (eg Update: new item). How can I get the expression to return a tuple such as (Update:, new item, None)? Thanks in advance, Mathieu -- http://mail.python.org/mailman/listinfo/python-list

urllib2: problem of handling space in parameter
Hi Folks, I encrountered a problem of using urllib2: the space handling. Look at the code below: import urllib2 url = r'http://somedomain.com/a.cgi?name=muddy coderpassword=foobar cgi_back = urllib2.urlopen(url).read() In this cgi_back, I saw field password worked fine, but field name not, only muddy was picked up by CGI. So, I had to cover the space, by using syntax name=muddy-coder, it went through. So, I presume urllib2 may have an approach of handling white space in this regard. Can anybody help? Thanks!

typedef (type alias) and ctypes
I try to create type aliases, like typedef in C (a specially aliases
to ctypes objects). This case:
some_type = c_ulong
oth_type = c_ulong
works in all cases but not with type qualification:
t1 = c_ulong # reference to c_ulong, nothing else :(
t2 = c_ulong
x = t1()
y = t2()
type(x)==type(y)
True
This trivial way for typedef doesn't allow to determine real type and
it's absolutely right :)
t1 = type('t1',(c_ulong,),{})
t2 = type('t2',(c_ulong,),{})
x = t1()
y = t2()
type(x)==type(y)
False
The problem:
1st way work in complex using of ctypes (interfacing with some DLLs),
but doesn't allow to determine real type!
2st way allows to determine real type, but access violation reading
0x000C' occurs in some DLL calls!
Question: what warts, errors are in 2nd way (may be reason of access
violation)?

I'm looking to split strings that ideally look like this: Update: New
item (Household) into a group.
This expression works ok: '^(Update:)?(.*)(\(.*\))$' - it returns
(Update, New item, (Household))
Some strings will look like this however: Update: New item (item)
(Household). The expression above still does its job, as it returns
(Update, New item (item), (Household)).
It does not work however when there is no text in parentheses (eg
Update: new item). How can I get the expression to return a tuple
such as (Update:, new item, None)?
I don't see how it can be done without some post-matching adjustment.
Try this:
C:\junktype mathieu.py
import re
tests = [
Update: New item (Household),
Update: New item (item) (Household),
Update: new item,
minimal,
parenthesis (plague) (has) (struck),
]
regex = re.compile(
(Update:)? # optional prefix
\s* # ignore whitespace
([^()]*)# any non-parentheses stuff
(\([^()]*\))? # optional (blahblah)
\s*# ignore whitespace
(\([^()]*\))? # another optional (blahblah)
$
, re.VERBOSE)
for i, test in enumerate(tests):
print Test #%d: %r % (i, test)
m = regex.match(test)
if not m:
print No match
else:
g = m.groups()
print g
if g[3] is not None:
x = (g[0], g[1] + g[2], g[3])
else:
x = g[:3]
print x
print
C:\junkmathieu.py
Test #0: 'Update: New item (Household)'
('Update:', 'New item ', '(Household)', None)
('Update:', 'New item ', '(Household)')
Test #1: 'Update: New item (item) (Household)'
('Update:', 'New item ', '(item)', '(Household)')
('Update:', 'New item (item)', '(Household)')
Test #2: 'Update: new item'
('Update:', 'new item', None, None)
('Update:', 'new item', None)
Test #3: 'minimal'
(None, 'minimal', None, None)
(None, 'minimal', None)
Test #4: 'parenthesis (plague) (has) (struck)'
No match
HTH,
John

Weird Indentation? (Or: is there a for...else construct?)
I've found something in the spirit of the following (in the epydoc sources, if you care): if True: print outer if for t in range(2): if True: print for if else: print phantom else For the life of me I can't place the else. Which if clause does it belong to? None, it would seem from running the above snippet: outer if For if For if Phantom else It seems that there is a for...else construct. Replacing the inner if with pass seems to confirm this. The else clause is still executed.

Newbie SWMixer / numpy help - AssertionError

BaseHTTPRequestHandler freezes while writing to self.wfile after installing Python 3.0
Hey guys, I'm starting to lose my head with this one. I have a class that extends BaseHTTPRequestHandler. It works fine on Python 2.5. And yesterday I was curious and decided to install Python 3.0 on my Mac (I followed this tutorial, to be sure I wasn't messing things up: http://farmdev.com/thoughts/66/python-3-0-on-mac-os-x-alongside-2-6-2-5-etc-/ ). I tried my application on Python 3.0 and the code just freezed on this line: self.wfile.write(f.read()) I searched and got to this bug http://bugs.python.org/issue3826 . I couldn't understand if there's already a fix for that. But, the strangest thing was that, when I tried my application on 2.5, it started freezing on the same spot! I then removed everything I installed from 3.0, fixed the paths, and it still gives me the error. I don't know what else to do. The app works fine on 2.5, because I tried it on another computer.

Re: Python3.0 has more duplication in source code than Python2.5
And I'm not saying that you can not have duplication in code. But it seems that the stable successful software releases tend to have relatively stable duplication rate. So if some software has an instable duplication rate, it probably means that it is either not stable, or not successful. In the case of Python 3.0, it's fairly obvious which one it is: it's not stable. Indeed, Python 3.0 is a significant change from Python 2.x. Of course, anybody following the Python 3 development process could have told you see even without any code metrics. I still find the raw numbers fairly useless. What matters more to me is what specific code duplications have been added. Furthermore, your Dup30 classification is not important to me, but I'm rather after the nearly 2000 new chunks of code that has more than 60 subsequent tokens duplicated. Regards, Martin -- http://mail.python.org/mailman/listinfo/python-list
Re: Python3.0 has more duplication in source code than Python2.5
But the duplication are always not very big, from about 100 lines (rare) to less the 5 lines. As you can see the Rate30 is much bigger than Rate60, that means there are a lot of small duplications. I don't find that important for code quality. It's the large chunks that I would like to see de-duplicated (unless, of course, they are in generated code, in which case I couldn't care less). Unfortunately, none of the examples you have posted so far are - large chunks, and - new in 3.0. Regards, Martin -- http://mail.python.org/mailman/listinfo/python-list

Hi,
I'm quite new to regular expressions, and I wonder if anyone here

I'm looking to split strings that ideally look like this: Update: New

This expression works ok: '^(Update:)?(.*)(\(.*\))$' - it returns
(Update, New item, (Household))
Some strings will look like this however: Update: New item (item)
(Household). The expression above still does its job, as it returns
(Update, New item (item), (Household)).
Not quite true; it actually returns
('Update:', ' New item (item) ', '(Household)')
However ignoring the difference in whitespace, the OP's intention is
clear. Yours returns
('Update:', ' New item ', '(item) (Household)')
It does not work however when there is no text in parentheses (eg
Update: new item). How can I get the expression to return a tuple
such as (Update:, new item, None)?
You need to make the last group optional and also make the middle group
lazy: r'^(Update:)?(.*?)(?:(\(.*\)))?$'.
Why do you perpetuate the redundant ^ anchor?
(?:...) is the non-capturing version of (...).
Why do you use
(?:(subpattern))?
instead of just plain
(subpattern)?

Can you explain this in a little more detail? In the application, there is one main numpy array of type O. Each element of the array corresponds to one cell in a grid. The user may enter a Python expression into the grid cell. The input is evaled and the result is stored in the numpy array (the actual process is a bit more complicated). Therefore, the object inside a numpy array element may be an inconsistent, nested, iterable type. The user now may access the result grid via __getitem__. When doing this, a numpy array that is as flat as possible while comprising the maximum possible data depth is returned, i.e.: 1. Non-string and non-unicode iterables of similar length for each of the cells form extra dimensions. 2. In order to remove different container types, the result is flattened, cast into a numpy.array and re-shaped. 3. Dimensions of length 1 are eliminated. Therefore, the user can conveniently use numpy ufuncs on the results. I am referring to the flatten operation in step 2 -- http://mail.python.org/mailman/listinfo/python-list
Re: Python3.0 has more duplication in source code than Python2.5
yet the general tone of the responses has been more defensive than i would have expected. i don't really understand why. nothing really terrible, given the extremes you get on the net in general, but still a little disappointing. I think this is fairly easy to explain. The OP closes with the question Does that say something about the code quality of Python3.0? thus suggesting that the quality of Python 3 is poor. Nobody likes to hear that the quality of his work is poor. He then goes on saying But it seems that the stable successful software releases tend to have relatively stable duplication rate. suggesting that Python 3.0 cannot be successful, because it doesn't have a relatively stable duplication rate. Nobody likes to hear that a project one has put many month into cannot be successful. Hence the defensive responses. i'm not saying there is such a solution. i'm not even saying that there is certainly a problem. i'm just making the quiet observation that the original information is interesting, might be useful, and should be welcomed. The information is interesting. I question whether it is useful as-is, as it doesn't tell me *what* code got duplicated (and it seems it is also incorrect, since it includes analysis of generated code). While I can welcome the information, I cannot welcome the conclusion that the OP apparently draws from them. Regards, Martin -- http://mail.python.org/mailman/listinfo/python-list

TkInter: Problem with propagation of resize events through geometry manager hierarchy?
Hi! I'm looking for help with a Tkinter program's handling of resize. I'm trying to do a fairly simple widget that shows a cropped part of a larger image, and let's you navigate within the larger image through a variety of methods. The widget hierarchy is: root ImageWidget (my class) Label (contains the image) Horizontal Scroll Bar Vertical scroll bar The cropping and scrolling works fine. But when I try to add responding to resize events, I get into trouble. Specifically: * When I naively change the size of the image shown to be borderwidth less than the size indicated in the configure event, the size of the image shown grows gradually but inexorably when I start the test app. (Sorta scary, actually :-}) * When I fiddle a bit to figure out what the actual difference in size is between the Configure event and the image that can be displayed, I get a vibrating, jagged display of the image. Investigation suggests that multiple configure events are hitting the label in response to each user resize with different sizes. I'm guessing that when I resize the image in response to those different events, that creates new resize events propagating through the window manager hierarchy, which creates new configure events, which means my handler changes the image size, which ... you get the idea. However, everything seems to work fine if I leave out the scroll bars and just have a label in a frame inside the root window; the image resizes fine. If the scroll bars are in place but I don't have the image resize bound to the configure event, I get two sets of resize events propagaing through the system on startup; without, I just get one. Event lists and code included below. Any help would be appreciated. Thanks! -- Randy Smith -- Event list on startup with scroll bars: receiving widget: width height root : 220 220 root : 1 1 iwidget : 220 220 root : 220 220 vscroll : 16 204 root : 16 204 hscroll : 204 16 root : 204 16 ilabel : 204 204 root : 204 204 vscroll : 15 205 root : 15 205 hscroll : 205 15 root : 205 15 ilabel : 205 205 root : 205 205 root : 219 219 ilabel : 205 205 root : 205 205 hscroll : 205 15 root : 205 15 vscroll : 15 205 root : 15 205 iwidget : 219 219 root : 219 219 vscroll : 15 204 root : 15 204 hscroll : 204 15 root : 204 15 ilabel : 204 204 root : 204 204 -- Event list on startup without scroll bars root : 204 204 root : 1 1 iwidget : 204 204 root : 204 204 ilabel : 204 204 root : 204 204 -- Code, without image resize.

Jan pf...@yahoo.com.br added the comment: hi all, just got bitten by this, so i took the time to reiterate the issue. according to the docs: http://docs.python.org/library/difflib.html find_longest_match() should return the longest matching string: If isjunk was omitted or None, find_longest_match() returns (i, j, k) such that a[i:i+k] is equal to b[j:j+k], where alo = i = i+k = ahi and blo = j = j+k = bhi. For all (i', j', k') meeting those conditions, the additional conditions k = k', i = i', and if i == i', j = j' are also met. In other words, of all maximal matching blocks, return one that starts earliest in a, and of all those maximal matching blocks that start earliest in a, return the one that starts earliest in b. but after a couple of hours debugging i finally convinced myself that the bug was in the library ... and i ended up here :) any ideas on how to work around this bug/feature, and just get the longest matching string ? (from a normal/newbie user perspective, that is, without patching the C++ library code and recompiling?) from the comments (which i couldn't follow entirely), does it use some concept of popularity that is not exposed by the API ? How is popularity defined ? many thanks! - jan ps.: using ubuntu's python 2.5.2 ps2.: and example of a string pair where the issue shows up: s1='Floor Box SystemsFBS Floor Box Systems - Manufacturer amp; supplier of FBS floor boxes, electrical ... experience, FBS Floor Box Systems continue ... raceways, floor box. ...www.floorboxsystems.com' s2='FBS Floor Box SystemsFBS Floor Box Systems - Manufacturer amp; supplier of FBS floor boxes, electrical floor boxes, wood floor box, concrete floor box, surface mount floor box, raised floor ...www.floorboxsystems.com' -- nosy: +janpf ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue1528074 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue5177] multiprocessing: SocketListener should use SO_REUSEADDR
New submission from Jon Dee j.a.t@gmail.com: Without this flag it is necessary to wait for e.g. 120s after closing down a 'BaseManager' server before restarting, due to the socket being in the TIME_WAIT state. Example error, which occurs if a server is started, data transmitted down the socket, the server shut down, then restarted: File /usr/local/lib/python2.6/multiprocessing/connection.py, line 220, in __init__ self._socket.bind(address) File string, line 1, in bind error: [Errno 48] Address already in use I added (locally): self._socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) to SocketListener.__init__, and it resolves the issue. -- components: Library (Lib) messages: 81336 nosy: jon_dee severity: normal status: open title: multiprocessing: SocketListener should use SO_REUSEADDR type: behavior versions: Python 2.6 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5177 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue4704] Update pybench for python 3.0
Antoine Pitrou pit...@free.fr added the comment: If possible, pybench should work unchanged in both Python 2.x and 3.x. Ok, the best I can do is to make it 2.6-compatible. For versions before 2.6, stuff like except Exception as e does not make compatibility reasonably achievable. ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4704 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue5178] Add content manager for temporary directory
New submission from Neil Schemenauer nas-pyt...@arctrix.com: I noticed that it would be nice to have a temporary directory context manager while trying to fix a broken unittest. The attached patch provides a pretty minimal implementation. There appears to be lots of unit tests that could use such a thing (just search for rmtree). I'm not sure if TemporaryDirectory is the best name. Also, perhaps it should have a __del__ method although that's tricky business. -- assignee: ncoghlan files: tempdir.patch keywords: patch messages: 81342 nosy: nascheme, ncoghlan severity: normal stage: patch review status: open title: Add content manager for temporary directory type: feature request Added file: http://bugs.python.org/file12970/tempdir.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5178 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue2047] shutil.destinsrc returns wrong result when source path matches beginning of destination path
Senthil orsent...@gmail.com added the comment: Sorry to bring this fixed-closed issue back again. I see that this was committed in a hurry. Either, shutil.destinsrc should be Documented, there currently does not exists any documentation to explain what destinsrc is supposed to do, or the function should be made _destinsrc to be internal only. I vote for the second approach of making it _destinsrc as it is used only in the shutil.move(). If no action can be taken on a closed bug, I shall open a new one and also attach a patch to make the method private. -- nosy: +orsenthil ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue2047 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
