ANNOUNCE: Hexerei 1.1
Hexerei 1.1! Description Hexerei is a colorful software package for Python (and optionally a web server) that assignsa color value to each word or letter in a database. Hexerei then utilizes the PIL to convert producean image consisting of color blocks which correspond to the given text. Thus, "a thousand words"become a picture! I have provided sourcecode access in HTML format for anyone to view. As all the importantfunctions are in a few scripts and run by another script, it is simple for users to import the codeand run it from a command line or interpreter. Features- Just set the permissions (witha web server) and run the code!- Tools are included for creating XHTML files on-the-fly.- Preferences can be set for many features.- Simple text documents are store encountered words and letters and to maintain a list of statistics. Licensing Hexerei is released under the GNU GPL.

Re: split a directory string into a list
Josef Meile wrote: This should work ***reasonably*** reliably on Windows and Unix. Are there any cases when it does not work? The most obvious case where it wouldn't work would be for a UNC path name. Using the string split method gives two empty strings: os.path.normpath(r'\\machine\share').split(os.path.sep) ['', '', 'machine', 'share'] whereas the splitpath function I proposed gives you: splitpath(r'\\machine\share') ['', 'machine', 'share'] So to find out the type of path (relative, absolute, unc), you only have to consider the first element with my function but you have to look at the first two elements if you just naively split the string. Also a relative windows path with a drive letter doesn't get fully split: os.path.normpath(r'c:dir\file').split(os.path.sep) ['c:dir', 'file'] splitpath(r'c:dir\file') ['c:', 'dir', 'file'] If you really are worried about speed (and are sure you aren't optimising prematurely), then you could combine some special case processing near the start of the string with a simple split of the remainder. -- http://mail.python.org/mailman/listinfo/python-list

class factory example needed (long)
I have a class factory problem. You could say that my main problem is that I don't understand class factories. My specific problem: I have a class with several methods I've defined. To this class I want to add a number of other class methods where the method names are taken from a list. For each list member, I want to build a method having the list member name so that I can override another method of the same name for objects which are instances of this class. Finally, I want my class factory which creates the method to call the overridden method. I'm sure my description is confusing, so I'll try to illustrate it. import Numeric # The Numeric module contains a whole lot of methods which operate on certain number types class foo: this is a number type class def __init__(self, value): self.value = float(value) def __str__(self): . . other methods here . import string ufuncs = string.split( sqrt arccos arccosh arcsin arcsinh arctan arctanh cos cosh tan tanh log10 sin sinh sqrt absolute fabs floor ceil fmod exp log conjugate )# these are the methods from Numeric that I want to override/wrap for my number type for u in ufuncs: I need something here which builds methods called sqrt(), arccos(), etc. An illustrative example of the class methods I want to build with some sort of class factory is def sqrt(self): val = Numeric.sqrt(self.value) return foo(Numeric.sqrt(self.value) + 42) def arccos(self): val = Numeric.arccos(self.value) return foo(Numeric.arccos(self.value) + 42) if __name__ == __main__: a = 9 b = foo(7) print Numeric.sqrt(a) print Numeric.sqrt(b) This would print 3 7 Note that the methods I want to create under program control are all identical in form. In this example they all call the wrapped method with an argument 42 greater than the value of the number. Does anyone have an example where they've done something similar or could help me out with an example? thanks in anticipation, Gary -- http://mail.python.org/mailman/listinfo/python-list

Not exactly sure what you're looking for but you can do the following: def dosomething(numlist): return numlist[0] + numlist[1] numlist = [ 5, 10] val = dosomething(numlist) If so, that would be somewhat pointless. It's always best to keep it simple. It looks like the function you wrote above is very adequate for the results you want returned. -- http://mail.python.org/mailman/listinfo/python-list
Making a calendar
Hi all. I'm trying to make a calendar for my webpage, python and html is the only programming languages that I know, is it possible to make such a calendar with pythong code and some html. The Idea is that when I click the link calendar on my webpage, then the user will be linked to the calendar. The calendar should show one month at the time, and the user should be able to browse to the other month. I will make a script that puts events and such into a db ( I know how to do this) Then I need a script that puts the events from the db into the calendar, if every day in the calendar has a value id that part will not be hard. What I need is a script that generates the calender, in such a way that each month will be have a value, and that the user then can click the days to see more info about the events. I was thinking something like the iMPcal calender: http://www.heidgerken.org/impcal2/calendar.php Is there any modules I can use, or does any of you hardcore programmers have some advice on how I should proceed with this little project of mine :) Thanks -- http://mail.python.org/mailman/listinfo/python-list
Problem When Unit Testing with PMock
Hi, Anyone was using pmock for unit testing with python? I met a problem and hope someone to help me. For short, the pmock seems can not mock a iterator object. For example, the tested object is foo, who need to send message to another object bar. So, to test the foo, I need mock a mockBar. But the bar is a iterator, the foo use the bar in this way: foo.method(self, bar): for n in bar: do somthing ... my purpose is create a mockBar and pass this mock object to foo.method(), but this ideal simply does not work. Python will complain that calling on an uniteraterable object. I'v already set anything like mockBar.expects(__iter__()) and mockBar.expects(next()).

I asked: I am developing a Python program that submits a command to each node of a cluster and consumes the stdout and stderr from each. I want all the processes to run in parallel, so I start a thread for each node.

(I could probably reduce to two threads per node by having the process thread handle stdout or stderr.)

As far as CGI is concerned, the POST data resides in stdin. So accessing it
is as simple as reading sys.stdin within the CGI script. Of course, it is up
to you to interpret the data, though you can just read everything as a
string. The POST data could just as well be binary - such as a file upload.
To dump the strings to a file to your webserver, try the following script:
import sys

dumped = open('test.txt', 'wb')

Note that the file object copies bytes from one place to another, via C library stdio. If we could only see the data in those stdio buffers, it would be possible to use file objects with select() in more applications. (Though not with pickle.) Since input very commonly needs to be buffered for various reasons, we end up writing our own buffer code, all because stdio has no standard function that tells you how much data is in a buffer. But unpickling consumes an I/O stream, as you observe, so as a network data protocol by itself, it's unsuitable for use with select. I think the only option would be a packet protocol - a count field followed by the indicated amount of pickle data. I suppose I would copy the received data into a StringIO object, and unpickle that when all the data has been received. Incidentally, I think I read here yesterday, someone held a book about Python programming up to some ridicule for suggesting that pickles would be a good way to send data around on the network. The problem with this was supposed to have something to do with overloading. I have no idea what he was talking about, but you might be interested in this issue.

People, ... sorry for the latching on on this broadside issue, but it is impotant ... here's are some germane points from another online discussion: the bug-reporting issue has came up so many times by so many people i thought i'd make a comment of my view. when a software is ostensibly incorrect, and if it is likely in connection to egregious irresponsibility as most software companies are thru their irresponsible licensing, the thing one should not do is to fawn up to their ass as in filing a bug report, and that is also the least effective in correcting the software. the common attitude of bug-reporting is one reason that contributed to the tremendous egregious irresponsible fuckups in computer software industry that each of us have to endure daily all the time. (e.g. software A clashed, software B can't do this, C can't do that, D i don't know how to use, E download location currently broken, F i need to join discussion group to find a work-around, G is all pretty and dysfunctional... ) when a software is ostensibly incorrect and when the company is irresponsible with their licensing, the most effective and moral attitude is to do legal harm to the legal entity. This one an do by filing a law suit or spreading the fact. Filing a law suit is appropriate in severe and serious cases, and provided you have such devotion to the cause. For most cases, we should just spread the fact. When a company see facts flying about their incompetence or irresponsibility, they will immediately mend the problem source, or cease to exist.

While from time to time bugs in Python are found, it's generally more productive to suspect one's own code.

Note that I don't know if this is the cause of your particular problem, just that it _is_ a bug. You've got two shared global variables, done and counter. Each of these is modified in a manner that is not thread-safe. I don't know if counter is causing trouble, but it seems likely that done is. Basically, the statement done += 1 is equivalent to the statement done = done + 1 which, in Python or most other languages is not thread-safe. The done + 1 part is evaluated separately from the assignment, so it's possible that two threads will be executing the done + 1 part at the same time and that the following assignment of one thread will be overwritten immediately by the assignment in the next thread, but with a value that is now one less than what you really wanted. Look at the bytecode produced by the statement done += 1: import dis def f(): ... global done ... done += 1 ... dis.dis(f) 3 0 LOAD_GLOBAL 0 (done) 3 LOAD_CONST 1 (1) 6 INPLACE_ADD 7 STORE_GLOBAL 0 (done) (ignore the last two lines: they just return None) 10 LOAD_CONST 0 (None) 13 RETURN_VALUE Note here the store_global that is separate from the add operation itself. If thread A gets loses the CPU (so to speak) just before that operation, and thread B executes the entire suite of operations, then later on when thread A executes that operation it will effectively result in only a single addition operation being performed, not two of them. If you really want to increment globals from the thread, you should look into locks. Using the threading module (as is generally recommended, instead of using thread), you would use threading.Lock(). There are other thread synchronization primitives in the threading module as well, some of which might be more suitable for your purposes. Note also the oft-repeated (in this forum) recommendation that if you simply use nothing but the Queue module for inter-thread communication, you will be very unlikely to stumble over such issues. -Peter -- http://mail.python.org/mailman/listinfo/python-list

You've got two shared global variables, done and counter. Each of these is modified in a manner that is not thread-safe. I don't know if counter is causing trouble, but it seems likely that done is. I understand that. As I said in my posting, The counter is incremented without locking -- I expect to see a final count of less than THREADS * COUNT. This is a test case, and I threw out more and more code, including synchronization around counter and done, until it got as simple as possible and still showed the problem. Basically, the statement done += 1 is equivalent to the statement done = done + 1 which, in Python or most other languages is not thread-safe. The done + 1 part is evaluated separately from the assignment, so it's possible that two threads will be executing the done + 1 part at the same time and that the following assignment of one thread will be overwritten immediately by the assignment in the next thread, but with a value that is now one less than what you really wanted. Understood. I was counting on this being unlikely for my test case. I realize this isn't something to rely on in real software. If you really want to increment globals from the thread, you should look into locks. Using the threading module (as is generally recommended, instead of using thread), you would use threading.Lock(). As my note said, I did start with the threading module. And variables updated by different threads were protected by threading.Condition variables. As I analyzed my test cases, and threading.py, I started suspecting thread scheduling. I then wrote the test case in my email, which does not rely on the threading module at all. The point of the test is not to maintain counter -- it's to show that sometimes even after one thread completes, the other thread never is scheduled again. This seems wrong. Try running the code, and let me see if you see this behavior. If you'd like, replace this: counter += 1 by this: time.sleep(0.01 * id) You should see the same problem. So that removes counter from the picture. And the two increments of done (one by each thread) are still almost certainly not going to coincide and cause a problem. Also, if you look at the output from the code on a hang, you will see that 'thread X: leaving' only prints once. This has nothing to do with what happens with the done variable.

I don't know if counter is causing trouble, but it seems likely that done is. I understand that. Basically, the statement done += 1 is equivalent to the statement done = done + 1 which, in Python or most other languages is not thread-safe. Understood. I was counting on this being unlikely for my test case. I realize this isn't something to rely on in real software. Hmm... okay. I may have been distracted by the fact that your termination condition is based on done incrementing properly, and that it was possible this wouldn't happen because of the race condition. So, if I understand you now, you're saying that the reason done doesn't increment is actually because one of the threads is never finishing properly, for some reason not related to the code itself. (?) The point of the test is not to maintain counter -- it's to show that sometimes even after one thread completes, the other thread never is scheduled again. This seems wrong. Try running the code, and let me see if you see this behavior. On my machines (one Py2.4 on WinXP, one Py2.3.4 on RH9.0) I don't see this behaviour. Across about fifty runs each. And the two increments of done (one by each thread) are still almost certainly not going to coincide and cause a problem. Also, if you look at the output from the code on a hang, you will see that 'thread X: leaving' only prints once. This has nothing to do with what happens with the done variable. Okay, I believe you. As I said, I hadn't taken the time to read through everything at first, jumping on an obvious bug related to the done variable not meeting your termination conditions. I can see that something else is likely to be causing this. One thing you might try is experimenting with sys.setcheckinterval(), just to see what effect it might have, if any. It's also possible there were some threading bugs in Py2.2 under Linux. Maybe you could repeat the test with a more recent version and see if you get different behaviour.

PyUnit and multiple test scripts
I'm trying to find the best way to use PyUnit and organize my test scripts. What I really want is to separate all my tests into 'test' directories within each module of my project. I want all the files there to define a 'suite' callable and to then all all those suites from all those test directories into one big suite and run it all. I'm having trouble with this. My first barrier was just loading the modules. As I had to be able to find them automatically (would be tedious to maintain a manual list of them) I needed to then load the modules from the paths to the files after I found them. This wasn't working, I just couldn't get it to load. I couldn't understand the imp module correctly. 1) Is there a very simple way to just take a file path and name, that I could use to open the source file, and load it as a module object, no strings attached? 2) Is there already a framework around that will do what I need?

This is one of the most important thing to understand about Python, in my opinion. There is a fundamental separation between an object and whatever names it is known by. Here's an example: def xxx(yyy): yyy[1] = 3 zzz = [ 0, 1, 2 ] xxx(zzz) After this code runs, zzz will be [0,3,2]. Note that, while xxx is running, the list that was created as [0,1,2] has two names.

The variable yyy is then bound to this NEW object, and its binding to the other list is lost. However, the variable zzz is still bound to [0,1,2].

Initial Comment:
It is common habit to see http headers:
import httplib
httplib.HTTPConnection.debuglevel = 1
import urllib
feeddata =
urllib.urlopen('http://diveintomark.org/xml/atom.xml').read()
but this dont work with import urllib2 with python 2.4
In rev 1.57 was intoduced code to AbstractHTTPHandler class
that prevent above mentioned construction.
Init method always set debuglevel=0 then do_open method
always do:
h.set_debuglevel(self._debuglevel)
after instantiating HTTPConnection class.

Initial Comment: OS: SuSE Linux 9.2 kernel 2.6.4 Python: 2.3.3 Define a class where the __init__() method takes a default arg of list type. Instantiate this class, and append/ extend the value of its default arg. Instantiate the class again, and the value from the first instance will overwrite the second. The bug is known to exist in 2.3.3, but may exist in subsequent releases also. The attached file illuminates the problem. -- You can respond by visiting: https://sourceforge.net/tracker/?func=detailatid=105470aid=1152726group_id=5470 ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[ python-Bugs-1110242 ] gzip.GzipFile.flush() does not flush all internal buffers
Bugs item #1110242, was opened at 2005-01-26 16:42 Message generated for change (Comment added) made by alanmcintyre You can respond by visiting: https://sourceforge.net/tracker/?func=detailatid=105470aid=1110242group_id=5470 Category: Python Library Group: Python 2.4 Status: Open Resolution: None Priority: 5 Submitted By: David Schnepper (dschnepper) Assigned to: Nobody/Anonymous (nobody) Summary: gzip.GzipFile.flush() does not flush all internal buffers Initial Comment: flush() is expected to output all pending data stored in internal buffers. gzip.GzipFile.flush() does perform a flush on its fileobj, but does not flush the state of its compressobj prior to the IO flush. This results in being able to use gzip.GzipFile to zip output to a socket and having the other side unzip it in sync with originators flush calls. -- Comment By: Alan McIntyre (ESRG) (alanmcintyre) Date: 2005-02-26 23:33 Message: Logged In: YES user_id=1115903 This patch appears to fix the bug as described, and running the regression tests on Python 2.5a0 (CVS HEAD) plus this patch turns up no problems. Since the documentation says that a GzipFile simulates most of the methods of a file object, I would expect GzipFile.flush() to act in the way that David described in the first paragraph of the bug report, and his patch seems to provide that as far as I can tell. -- You can respond by visiting: https://sourceforge.net/tracker/?func=detailatid=105470aid=1110242group_id=5470 ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[ python-Bugs-1152762 ] curses.textpad raises error
Bugs item #1152762, was opened at 2005-02-27 19:00 Message generated for change (Tracker Item Submitted) made by Item Submitter You can respond by visiting: https://sourceforge.net/tracker/?func=detailatid=105470aid=1152762group_id=5470 Category: Python Library Group: Python 2.3 Status: Open Resolution: None Priority: 5 Submitted By: John McPherson (jrm21) Assigned to: Nobody/Anonymous (nobody) Summary: curses.textpad raises error Initial Comment: textpad seems to have a bug when you backspace from the start of a line. By default, stripspaces is on, so it tries to skip any spaces on the previous line. But if there are no spaces, it raises a curses error and makes the app quit. Reproduce by: $ python /usr/lib/python2.3/curses/textpad.py type 1234567890 into the textpad press backspace twice. The problem is _end_of_line() function doing last = last + 1 I think a better way would be to start at the end of the line (last=self.maxx), and skip backwards while last is a space: while last 0 and ascii.ascii(self.win.inch(y, last)) == ascii.SP: last -= 1 -- You can respond by visiting: https://sourceforge.net/tracker/?func=detailatid=105470aid=1152762group_id=5470 ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
