I copied the lines
f=open('/tmp/workfile', 'w')
print f
f.close()
from Python 2.4 Documentation 7.2. But it said IOerror No such file or
directory '/tmp/workfile'
Is it something about the os? I'm using Python 2.4 under WinXP.
Thanks. Without / I can open it.
In addition to what others said, if you need to open a temporary file,
it's better to use os.tmpfile() to get a file descriptor and not to
rely on magic file names like '/tmp/workfile'. So instead of open()
you should do:
import os
f = os.tmpfile()
This should work fine of both Windows and UNIX systems.

Hi,
My string is a multi line string that contains filename
filename\n and host host\n entries among other things.
For example: s = filename X
host hostname1
blah...
host hostname2
blah...
filename Y
host hostname3
Given a host name, I would like to get its filename (The closest
filename reading backwards from the host line). I could read each line
until I hit the host name, but I am looking for an RE that will do job.
The answer should be Y for host hostname3 and X for either host
hostname1 or hostname2.
Thanks in advance.

print Names_Filter (s)

Re: Newbie..Needs Help
Graham,
Would it help to use another web site? Not as long as the program works on this
site. If it doesn't it may help to change sites, but
a new reader would have to be crafted. Towards this my code may look
intimidating. It isn't really a good example for a demo,
because it looks scary. As I said, I experimentally stretched the envelope.
The trick is to develop incrementally, one step at a time, look at the
result of each stage, recognize what needs to be done
next and add missing definitions or add a subsequent translation step. In this
manner a complex system can be built. SE is
particualry accommodating in this respect. You can test an Editor object in
seconds on the IDLE command line, e.g.:
s = 'Total: $1,234.55 (-6.7)'
print SE.SE ('$=USD ,=\' .=, := )=%)') (s)
TotalUSD 1'234,55 (-6,7%)
It also helps to read SE-DOC.HTM which explains a host of basic techniques.
Glad to help
Frederic

Graham,
Only a few days ago I gave someone a push who had a very similar problem.
I handed him code ready to run. I am doing it again for
you.
The site you use is much harder to interpret than the other one was
and so I took the opportunity to experimentally stretch
the envelope of a new brain child of mine: a stream editor called SE. It
is new and so I also take the opportunity to demo it.
One correspondent in the previous exchange was Paul McGuire, the
author of 'pyparse'. He made a good case for using 'pyparse'
in situations like yours. Unlike a stream editor, a parser reads structure
in addition to data and can relate the data to its
context.
Anlayzing the tables I noticed that they are poorly structured: The
first column contains both data and ids. Some records are
shorter than others, so column ids have to be guessed and hard coded.
Missing data sometimes is a dash, sometimes nothing. The
inconsistencies seem to be consistent, though, down the eight tables of
the page. So they can be formalized with some confidence
that they are systematic. If Paul could spend some time on this, I'd be
much interested to see how he would handle the relative
disorder.
Another thought: The time one invests in developing a program should
not exceed the time it can save overall (not talking
about recreational programming). Web pages justify an extra measure of
caution, because they may change any time and when they do
they impose an unscheduled priority every time the reader stops working
and requires a revision.
So, here is your program. I write it so you can copy the whole thing to a
file. Next copy SE from the Cheese Shop. Unzip it and put
both SE.PY and SEL.PY where your Python progams are. Then 'execfile' the
code in an IDLE window, call 'display_horse_race_data
('Bendigo', '27/07/2006') and see what happens. You'll have to wait ten
seconds or so.

You also don't expect the identity of a and b to be the same after assigning one to the other. You can create C++ classes that behave like that (you can implement Python in C++ :), but that doesn't mean that you expect C++ language constructs to behave like that.

how to make python socket server work with the app.MainLoop() in wxpython?
Hi everyone,
I am using a python socket server to collect data from a socket
client and then control a image location ( wxpython) with the data,
i.e. moving the image around in the wxpython frame.
But the app.MainLoop() in wxpython looks like conflicting with
the while 1: in socket server. After I commented the
app.MainLoop(), everything is working except two things:
1. if I click anywhere on the screen with the mouse, the image is
gong and only the empty frame( or panel) is left.
2. if I don't touch anything, the image is being moved around but
the previous images are left behind in the panel.
I guess that may be caused by app.MainLoop() commented.
Anybody knows how to make the two things work together? I really
appreciate your help.
My sample code is modified based on the wxpython demo: image.py.
socket client is also attached for your reference.

client and then control a image location ( wxpython) with the data,
i.e. moving the image around in the wxpython frame.
But the app.MainLoop() in wxpython looks like conflicting with
the while 1: in socket server. After I commented the
app.MainLoop(), everything is working except two things:
1. if I click anywhere on the screen with the mouse, the image is
gong and only the empty frame( or panel) is left.
2. if I don't touch anything, the image is being moved around but
the previous images are left behind in the panel.
I guess that may be caused by app.MainLoop() commented.
Anybody knows how to make the two things work together? I really
appreciate your help.
My sample code is modified based on the wxpython demo: image.py.
socket client is also attached for your reference.

If you get rid of app.MaiLoop(), you basically get rid of all GUI events.
You need to have you server in a separate thread.

Possibly, but at this point I'm still trying to understand how Python does these things, and what the useful abstraction level is for me. I also still have very little experience how I'll put the things we've been discussing here into (Python) practice. While not new to programming, I'm new to Python. AFAIU, one can also build a C++ class hierarchy that with some small limitations in used operators, would have semantics very similar to Python. Would you argue that those using such a C++ class hierarchy would no longer be using variables in C++? Probably not. But for me it's mostly about useful terminology, not necessarily correct terminology. In order to talk about correct terminology, we'd have to use a common definition of variable. This is a term so widely used that I'm not sure there is a useful single definition of it; do you know one? A name in a scope to which is attached some value/object. Now whether this attachment is in the form of storage or binding is IMO not that important. In any case, the following doesn't seem to be implementation detail (and rather a part of the language), but it's not really understandable with a C++ concept of variable: a=3 id(a) 3368152 b=a id(b) 3368152 b=4 id(b) 3368140 You don't expect the identity of the variable b to change with a simple assignment from a C/C++ point of view. That depends on what you call the identity. If I had to translate this into C++ it would be something like: int *a, *b; a = MakeInt(3); b = a; b = MakeInt(4); AFAIU, you can wrap these int pointers into some kind of class, so that they behave as you would expect integers to behave. The id(a) would just return a, the address of where the integer is stored. Now whether this is helpfull or not for you in understanding the python behaviour, I don't know. So if you think this is mixing to many things I'll drop it. You also don't expect the identity of a and b to be the same after assigning one to the other. You can create C++ classes that behave like that (you can implement Python in C++ :), I'm sorry but IMO you there is no connection between those two. C doesn't have classes, yet you can still implement Python in C. but that doesn't mean that you expect C++ language constructs to behave like that.

This is as simple as it can get. I just derive from Parent and i get my
proper count (added to my parent's if i wish so).
I wish i could achieve such a code purity in C++.
Well, I hope you understand that this code purity is possible only
because of the *dynamic* lookup of the variable name ... Thus, the same
function, once compiled, will be able to determine, at runtime, where
the current variable lies ... At the same time, tries, in Python, to
achieve the count of *all* the instances of a class, meaning that you want :
a = Parent()
b = Child()
c = Parent()
d = Child()
print Child.getcount() # 2
print Parent.getcount() # 4
That time, the automatic name lookup will come in the way as you cannot
have two count variables accessible from the same class.
For C++ the problem is inverse, you have a way to obtain the second
thing (using templates or macro), but the first is harder.

Mouse LED Control in Python
I found this link that describes the byte arrays to control the
IM/Email Leds on my Logitech MX610 mouse:
http://www.kdedevelopers.org/node/2029
The link to the tarball is dead so I can't look at that. Is there
anyway to do what the link says in Python? If you follow the link
above, it talks about 'sending the byte array to 0x10 (16)'. I'm not
sure if that is possible in python. Can anyone help or point me in the
right direction? I'd also be willing to have this be done in another
language and just call different programs from a python program when I
need something specific done (IM light on, for example).
Text from the link if you can't be bothered to follow it:
I've figured out the IM led now. As before, you send 6 bytes to report
ID 0x10
(16), followed by the confirm message.
The magic values are:
unsigned char confirm[6] = { 0x01, 0x80, 0x52, 0x00, 0x00, 0x00 };
unsigned char email_off[6] = { 0x01, 0x80, 0x52, 0x06, 0x00, 0x00 };
unsigned char email_on[6] = { 0x01, 0x80, 0x52, 0x05, 0x00, 0x00 };
unsigned char email_pulse[6] = { 0x01, 0x80, 0x52, 0x04, 0x00, 0x00 };
unsigned char email_flash[6] = { 0x01, 0x80, 0x52, 0x03, 0x00, 0x00 };
unsigned char email_instanton[6] = { 0x01, 0x80, 0x52, 0x02, 0x00, 0x00
};
unsigned char email_instantoff[6] = { 0x01, 0x80, 0x52, 0x01, 0x00,
0x00 };
unsigned char im_off[6] = { 0x01, 0x80, 0x52, 0x00, 0x06, 0x00 };
unsigned char im_on[6] = { 0x01, 0x80, 0x52, 0x00, 0x05, 0x00 };

I'll try.
first of all python is not going to be used for my purpose (sigh)
I have device A which holds a binary coded decimal array [N1,N2,Nn]
where the array represents a decimal number.
In C: unsigned char dec[] = {1,2,3,4,5,6,7,8};
I need that array converted for device B into an array where each element
represents the actual byte value.
In C: the result would be unsigned char hex[] = {0x1,0x2,0xD,0x6,0x8,0x7};
I guess any pocket calculator goes through that process for dec/hex
conversion.
Hope that's clearer.

Not really. Maybe I'm missing something obvious but I don't see the link
between your `dec` and `hex` values. 12345678 converted to hex is
bc614e. Do you need such a conversion? And should the result really be
one nibble (4 bit)/hex digit per array entry!?

Execution timeout
X-No-Archive: yes Hi, I'm using feedparser to parse some xml feeds. As others reported (http://sourceforge.net/tracker/index.php?func=detailaid=1519461group_id=112328atid=661937 ) the library halts while parsing some feeds. To overcome this issue I was thinking about creating some kind of wrapper for feedparser that encapsulates a timeout. So after launching the parse method wait a few seconds and if the control does not return mark the feed as bad. I haven't much experience with Python so I'm not able to code it, any hint? Is there a better method to avoid this kind of problem? Thanks, Lorenzo -- http://mail.python.org/mailman/listinfo/python-list

This is untested, but should give you the idea:
First, convert that list to a decimal digit string:
s = ''.join(map(str, l1))
Then convert the string to an integer:
n = int(s)# base 10 is the default
Then convert the integer to a hex digit string:
h = '%X' % n
Finally, convert the hex digit string to a list of integer values of the
individual digits:
vlist = [int(d, 16) for d in h]
This is the list you want.
If you prefer, You can do it all in one line:

ftplib errors/exceptions
I'm new to Python and I am writing a simple FTP client. I am having trouble handling errors like connection refused, invalid username or password, and the like. I can use a try exception block like thistry: ftp=FTP('some_server')
ftp.login() # more linesexcept: print An error has occured.\nThis works fine to supress the errors, but I would like to be able to narrow the errors down so that I can print 'invalid username or password' or 'connection refused' rather than simply 'An error has occured'. How would I go about narrowing down which errors occur?

You are apparently on Linux or so, so I can't track this problem down
having only a Windows box here, but inbetween I know that there is
another problem with it:
I have erronously assumed, that the numbers in #1087; are hexadecimal,
but they are decimal, so it is necessary to do hex(int('1087')) on them
to get at the right code to put into eval().
As you know now the idea I hope you will succeed as I did with:
lstIntUnicodeDecimalCode = strHTML.replace('#','').split(';')
lstIntUnicodeDecimalCode
['1087', '1088', '1080', '1074', '1077', '1090', ' 1087', '1080',
'1090', '1086', '1085', '']
lstIntUnicodeDecimalCode = lstIntUnicodeDecimalCode[:-1]
lstHexUnicode = [ hex(int(item)) for item in lstIntUnicodeDecimalCode]
lstHexUnicode
['0x43f', '0x440', '0x438', '0x432', '0x435', '0x442', '0x43f', '0x438',

Re: Small problem with print and comma
I have a small problem with my function: printList. I use print with a ',' . Somehow the last digit of the last number isn't printed. I wonder why. Posting actual code might help...the code you sent has a horrible mix of tabs and spaces. You've also got some craziness in your creating random list string. First off, it looks like you're using a docstring, but they only go immediately after the def line. I'd recommend putting it where it belongs, or changing the line to a comment. There are some unpythonic bits in here: printList() would usually just idiomatically be written as print ' '.join(a) although there are some int-to-string problems with that, so it would be written as something like print ' '.join([str(x) for x in listOfNumbers]) which is efficient, and avoids the possibility of off-by-one errors when range(0,length). Another idiom would be the list-building of createRandomList: return [random.randrange(100) for x in xrange(0,length)] Additionally, this can be reduced as range/xrange assume 0 as the default starting point return [random.randrange(100) for x in xrange(length)] (using xrange also avoids building an unneeded list, just to throw it away) Additionally, rather than rolling your own bubble-sort, you can just make use of a list's sort() method: a.sort() Other items include sensibly naming your parameters rather than generically calling them param, just to reassign them to another name inside. Taking my suggestions into consideration, your original program condenses to import random def createRandomList(length): return [random.randrange(100) for x in xrange(length)] def printList(listOfNumbers): print ' '.join([str(x) for x in listOfNumbers]) if __name__ == __main__: length = 10 a = createRandomList(length) printList(a) a.sort() print sorted list printList(a) one might even change createRandomList to allow a little more flexibility: def createRandomList(length, maximum=100): return [random.randrange(maximum) for x in xrange(length)] So it can be called as you already do, or you can specify the maximum as well with createRandomList(10, 42) for future use when 100 doesn't cut it for you in all cases.

re: how to stop python
bruce bedouglas at earthlink.net posted: perl has the concept of die. does python have anything similar. how can a python app be stopped? I see this sort of statement a lot in Perl: open(FH, myfile.txt) or die (Could not open file); I've no idea why you're asking for the Python equivalent to die, but if it's for this sort of case, you don't need it. Usually in Python you don't need to explicitly check for an error. The Python function will raise an exception instead of returning an error code. If you want to handle the error, enclose it in a try/except block. But if you just want the program to abort with an error message so that you don't get silent failure, it will happen automatically if you don't catch the exception. So the equivalent Python example looks something like this: fh = file(myfile.txt) If the file doesn't exist, and you don't catch the exception, you get something like this: $ ./foo.py Traceback (most recent call last): File ./foo.py, line 3, in ? fh = file(myfile.txt) IOError: [Errno 2] No such file or directory: 'myfile.txt' /Dan -- http://mail.python.org/mailman/listinfo/python-list

You are apparently on Linux or so, so I can't track this problem down
having only a Windows box here, but inbetween I know that there is
another problem with it:
I have erronously assumed, that the numbers in #1087; are hexadecimal,
but they are decimal, so it is necessary to do hex(int('1087')) on them
to get at the right code to put into eval().
As you know now the idea I hope you will succeed as I did with:
lstIntUnicodeDecimalCode = strHTML.replace('#','').split(';')
lstIntUnicodeDecimalCode
['1087', '1088', '1080', '1074', '1077', '1090', ' 1087', '1080',
'1090', '1086', '1085', '']
lstIntUnicodeDecimalCode = lstIntUnicodeDecimalCode[:-1]
lstHexUnicode = [ hex(int(item)) for item in lstIntUnicodeDecimalCode]
lstHexUnicode

Using the cookbook's method (below) works but I think the replace fxn chokes on such a large chunk of text.

There's got a be quick and dirty (and cheap) way to do this... any help? Cookbook's method: output_file.write(input_file.read().replace(stext, rtext)) Thanks, Pythonner The read() method of a file will read all data until EOF is reached if you don't pass it a size argument. If your file is several hundred MB and your RAM is not, you may have some trouble with this. I don't know how well the replace() method works on tenths-of-a-GB strings. The file object supports line-by-line reads through both the readline() and readlines() methods, but be aware that the readlines() method will also try to read ALL the data into memory at once unless you pass it a size argument. You can also iterate through the lines in an open file object like so: for line in input_file: # Do something with the line here. so, if you know that you want to replace a whole actual line, you could do this like so: for line in input_file: if line == stext: output_file.write(rtext) else: output_file.write(line) Check out the docs on the file object for more info: http://docs.python.org/lib/bltin-file-objects.html HTH, ~Simon -- http://mail.python.org/mailman/listinfo/python-list

Or did you want a literal recipe

print the integer to string using Hex format code

Löwis (loewis) Summary: W3C - Python DOM type mapping docs need updating Initial Comment: I believe the information at http://docs.python.org/lib/dom-type-mapping.html is outdated; most if not all boolean return values, at least in minidom, are handled as BooleanType, not IntegerType. This should be standard. Sorry, I don't have a patch to submit for this. Should be an easy fix though. -- Comment By: Martin v. Löwis (loewis) Date: 2006-07-30 09:25 Message: Logged In: YES user_id=21627 I agree with Fred that the documentation is not wrong as it stands. As this section is meant to apply not only to minidom, but to all Python DOM implementations, I don't think the specification can be changed. minidom would probably still comply (except perhaps for the specified attribute), but other implementations might comply anymore. If clarification is needed, it should go beyond boolean: What is IntegerType? There is no type with that name in Python, and, indeed, unsigned long cannot alway map to types.IntType; unsigned long long (used for DOMTimeStamp) and unsigned short don't get mapped at all in the table. I think the intention is this: for the proper IDL integer types (short, long, long long, +unsigned), both Python int and long can be used. For boolean, int, long, and bool can be used; on input, any non-zero value counts as true, and on output, only 0 or 1 should be returned (where bool(0) is False and bool(1) is True). -- Comment By: Fred L. Drake, Jr. (fdrake) Date: 2006-07-30 06:56 Message: Logged In: YES user_id=3066 My position on this is that: 1) The docs are not wrong. 2) The docs should be updated to indicate that bool values are returned where appropriate. 3) It is reasonable that Python developers know the relationship between bool and int. That is not something that can reasonably change in Python 2.x. It seems unlikely to change for Python 3000. 4) The strict application of the IDL mapping really hasn't helped in creating a good DOM-like interface for Python. Dealing with the last item isn't within scope for handling this issue. -- Comment By: Mike Brown (mike_j_brown) Date: 2006-06-03 23:01 Message: Logged In: YES user_id=371366 If answer #1 is chosen and the others rejected, then the docs remain misleading, since the average reader just wants to know what types to expect from an implementation (or should code into their implementation), and shouldn't be expected to know the relationship between Booleans and integers. Is it even reasonable to expect that this relationship will always be true? In any case, I'd rather see it made explicit as to why minidom doesn't seem, at first, to respect the type mapping, at least in current implementations. It could be as simple as adding Andrew's comment, phrased as This DOM mapping is derived from the IDL mapping for Python, which predates the introduction of BooleanType, which is currently a subtype of IntegerType. Implementations may use either type. or some such. -- Comment By: A.M. Kuchling (akuchling) Date: 2006-06-03 22:42 Message: Logged In: YES user_id=11375 Martin, you probably need to make a pronouncement on this. The DOM mapping is supposed to be derived from the IDL mapping for Python, which predates Booleans, but methods such as hasChildNodes() return True/False. I can see at least three answers: 1) Booleans are subtypes of integers, so the docs are not wrong. 2) The docs are wrong and should say Boolean. 3) The methods should be returning regular 0 and 1, not True and False, and should be changed. -- You can respond by visiting: https://sourceforge.net/tracker/?func=detailatid=105470aid=1495229group_id=5470 ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Submitted By: Erik Demaine (edemaine)
Assigned to: A.M. Kuchling (akuchling)
Summary: file.write + closed pipe = no error
Initial Comment:
I am writing a Python script on Linux that gets called
via ssh (ssh hostname script.py) and I would like it to
know when its stdout gets closed because the ssh
connection gets killed. I assumed that it would
suffice to write to stdout, and that I would get an
error if stdout was no longer connected to anything.
This is not the case, however. I believe it is because
of incorrect error checking in Objects/fileobject.c's
file_write.
Consider this example:
while True:
__print 'Hello'
__time.sleep (1)
If this program is run via ssh and then the ssh
connection dies, the program continues running forever
(or at least, over 10 hours). No exceptions are thrown.
In contrast, this example does die as soon as the ssh
connection dies (within one second):
while True:
__os.write (1, 'Hello')
__time.sleep (1)
I claim that this is because os.write does proper error
checking, but file.write seems not to. I was surprised
to find this intricacy in fwrite(). Consider the
attached C program, test.c. (Warning: If you run it,
it will create a file /tmp/hello, and it will keep
running until you kill it.) While the ssh connection
remains open, fwrite() reports a length of 6 bytes
written, ferror() reports no error, and errno remains
0. Once the ssh connection dies, fwrite() still
reports a length of 6 bytes written (surprise!), but
ferror(stdout) reports an error, and errno changes to 5
(EIO). So apparently one cannot tell from the return
value of fwrite() alone whether the write actually
succeeded; it seems necessary to call ferror() to
determine whether the write caused an error.
I think the only change necessary is on line 2443 of
file_write() in Objects/fileobject.c (in svn version
46003):
2441n2 = fwrite(s, 1, n, f-f_fp);
2442Py_END_ALLOW_THREADS
2443if (n2 != n) {
2444PyErr_SetFromErrno(PyExc_IOError);
2445clearerr(f-f_fp);
I am not totally sure whether the n2 != n condition
should be changed to n2 != n || ferror (f-f_fp) or
simply ferror (f-f_fp), but I believe that the
condition should be changed to one of these
possibilities. The current behavior is wrong.
Incidentally, you'll notice that the C code has to turn
off signal SIGPIPE (like Python does) in order to not
die right away. However, I could not get Python to die
by re-enabling SIGPIPE. I tried signal.signal
(signal.SIGPIPE, signal.SIG_DFL) and signal.signal
(signal.SIGPIPE, lambda x, y: sys.exit ()) and neither
one caused death of the script when the ssh connection
died. Perhaps I'm not using the signal module correctly?
I am on Linux 2.6.11 on a two-CPU Intel Pentium 4, and
I am running the latest Subversion version of Python,
but my guess is that this error transcends most if not
all versions of Python.

A simple test case is this Python script (fleshed out from
previous example), also attached:
import sys, time
while True:
__print 'Hello'
__sys.stdout.flush ()
__time.sleep (1)
Save as blah.py on machine foo, run 'ssh foo python blah.py'
on machine bar--you will see 'Hello' every second--then, in
another shell on bar, kill the ssh process on bar. blah.py
should still be running on foo. ('foo' and 'bar' can
actually be the same machine.)
The example from the original bug report that uses
os.write() instead of print was an example that *does* work.

I agree with your analysis, and think your suggested fixes are correct.
However, I'm unable to construct a small test case that exercises this bug. I
can't even replicate the problem with SSH; when I run a remote script with
SSH and then kill SSH with Ctrl-C, the write() gets a -1. Are you terminating
SSH in some other way? (I'd really like to have a test case for this problem
before committing the fix.)

Löwis (loewis) Date: 2005-03-03 22:50 Message: Logged In: YES user_id=21627 This seems to be a bug report, not a patch, so I'm reclassifying it. Is there any chance that you tried os.remove as a superuser? Python invokes unlink; according to the OS man page, unlink gives EPERM when the file to remove is a directory. I consider this a bug in the operating system: it should not be possible, not even for the superuser, to corrupt the file system using standard system calls. I don't know what the rationale is for this behaviour. -- You can respond by visiting: https://sourceforge.net/tracker/?func=detailatid=105470aid=1153417group_id=5470 ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Summary: popen3 on windows loses environment variables
Initial Comment:
see the following test code:
#test_popen3_1.py
import os
FILENAME='c:\temp\test_popen3_2.py'
os.environ['FOOBAR']='foobar'
print os.environ['FOOBAR']
fs=os.popen3(c:\python24\python -u %s%
FILENAME,'b')
print fs[1].read()
#c:\temp\test_popen3_2.py
print from test_popen3_2.py
import os;print os.environ['FOOBAR']
Running test_popen3_1.py is expected to print out:
foobar
from test_popen3_2.py
foobar
But it doesn't print the last foobar. It correctly prints
out when run on python 2.3.
If the FILENAME is set to a relative path, as when you
are in the c:\temp directory and the FILENAME is set to
test_popen3_2.py, the code works correct.
Tests run on windows XP, SP1.
This bug is related to the cgi bug #1100235.

Now I got it. The reason is os.py in python2.4 has changed
so that the _Environ(UserDict.IterableUserDict) has lost its
update method -- there was on in python2.3.
To rectify the problem you just copy and paste the update
method from python2.3 os.py.

Oh, stupid me. The full path filename included '\t'. It
should've been escaped. Then the example code works with 2.3
and 2.4.
The real problem seems to be with os.environ.
I have reassured this problem exists on some XP SP1 boxes.
The test code is...
#test_popen3_1.py
import os
FILENAME='test_popen3_2.py'
env={};env['ENVIRON_UPDATE']='123';os.environ.update(env)
os.environ['ENVIRON_DIRECT_SETTING']='123'
cmdline='c:\python24\python.exe -u %s'%FILENAME
fs=os.popen3(cmdline,'b')
print fs[1].read()
#test_popen3_2.py
import os
if os.environ.has_key('ENVIRON_UPDATE'):print 'os.env.update
worked'
else:print 'os.env.update failed'
if os.environ.has_key('ENVIRON_DIRECT_SETTING'):print
'os.env assignment worked'
else:print 'os.env assignment failed'
Put these two files in the same path and run
test_popen3_1.py with python2.4 and python2.3.
Following is the result I got:
C:\test\python23\python test_popen3_1.py
os.env.update worked
os.env assignment worked
C:\test\python24\python test_popen3_1.py
os.env.update failed
os.env assignment worked
As you see the environment varaible that's updated with
os.environ.update has failed to get passed to popen3ed process.
This is the reason CGIHTTPServer.py fails to deliver
QUERY_STRING and etc. -- they are updated with
os.environ.update(env).

I've tried recreating this problem and have had no luck. I've
tried three versions of python: 2.3, 2.4, and the current
build version (2.5 something?). I've also tried both absolute
and relative paths. All tests print out the second 'foobar' just
fine. I, too, am running XP, SP1.
Any chance there's something special about how you are
running the executables? Say from a cygwin environment or
something?

Summary: Bug in shutil.copytree on Windows
Initial Comment:
The problem is that the call to 'copystat(src, dst)'
was added to the shutil.copytree function, in svn
r38363 probably. It will fail always on Windows, since
os.utime does not work on directories.
I guess that a patch similar to this one should fix it:

The following should work as a test method for shutil.copytree
(Passes on my box against a patched version of shutil)
def test_copytree_simple(self):
src_dir = tempfile.mkdtemp()
dst_dir = os.path.join(tempfile.mkdtemp(),
'destination')
open(os.path.join(src_dir, 'test.txt'),
'w').write('123')
os.mkdir(os.path.join(src_dir, 'test_dir'))
open(os.path.join(src_dir, 'test_dir', 'test.txt'),
'w').write('456')
#
def testStat(src, dst):
st_src = os.stat(src)
st_dst = os.stat(dst)
if hasattr(os, 'utime'):
self.assertEqual((st_src.st_atime,
st_src.st_mtime), (st_dst.st_atime, st_dst.st_mtime))
if hasattr(os, 'chmod'):
# Should be equal anyway, should we change
permissions on one of the source files ?
self.assertEqual(stat.S_IMODE(st_src.st_mode),
stat.S_IMODE(st_dst.st_mode))
#
try:
shutil.copytree(src_dir, dst_dir)
self.assertTrue(os.path.isfile(os.path.join(dst_dir,
'test.txt')))
self.assertTrue(os.path.isdir(os.path.join(dst_dir,
'test_dir')))
self.assertTrue(os.path.isfile(os.path.join(dst_dir,
'test_dir', 'test.txt')))
self.assertEqual(open(os.path.join(dst_dir,
'test.txt')).read(), '123')
self.assertEqual(open(os.path.join(dst_dir,
'test_dir', 'test.txt')).read(), '456')
finally:
try:
os.remove(os.path.join(src_dir, 'test.txt'))
os.remove(os.path.join(dst_dir, 'test.txt'))
os.remove(os.path.join(src_dir, 'test_dir',
'test.txt'))
os.remove(os.path.join(dst_dir, 'test_dir',
'test.txt'))
os.removedirs(src_dir)
os.removedirs(dst_dir)
except:
pass
Can turn the above into a patch tonight if needed.

Two problems: First, this error message is emitted on win32, but it appears to be incorrect, inasmuch as the Microsoft compiler is not actually required: error: Python was built with version 7.1 of Visual Studio, and extensions need to be built with the same version of the compiler, but it isn't installed. Error: Subprocess exited with result 1 for project core Second, the usage of distutils is somewhat confusing, as the following line emits that error message: ./setup.py build -c mingw32; ./setup.py install but the following line, which I intuitively believed to be equivalent at first, works to compile and install the package: ./setup.py build -c mingw32 install -- Comment By: Martin v.
