Re: "Cloning" file attributes and permissions
If you know what the permissions are going to be then you can use umask to set the default file creation permissions to match. Then any files created in that directory will have the correct permissions. I think the "pythonic" way to solve this problem would be to code up your own module which handles all the dirty parts in the background. It would create the new file, stat the original, and chmod/chown the new file as needed to match the original. All you would have to do after creating the module is pass the new function the original and new file information. -- Kevin Kelley On 4/12/07, Paulo da Silva <[EMAIL PROTECTED]> wrote: [EMAIL PROTECTED] escreveu: > On Apr 12, 5:19 pm, [EMAIL PROTECTED] wrote: >> On Apr 12, 4:09 pm, Paulo da Silva <[EMAIL PROTECTED]> wrote: >> ... > > After poking around a bit I also discovered the > shutil module.

Re: "Cloning" file attributes and permissions
This is what I (just now) put together as an example:
from os import stat,mknod,chown
def match_perms(org_fname,new_fname):
# Get information on old file
st = stat(org_fname)
st_mode = st.st_mode
st_uid = st.st_uid
st_gid = st.st_gid
# Create the new file
mknod(new_fname,st_mode)
# Matching permissions
chown(new_fname,st_uid,st_gid)
if __name__ == "__main__":
match_perms('old_filename','new_filename')

2007 DST Changes
Is python affected by the 2007 DST changes in the US? Other than making sure the OS is patched correctly (Win 2K and Solaris 8) is there anything else that needs to be done from a Python point of view? Thanks, Kevin Kelley -- http://mail.python.org/mailman/listinfo/python-list
Re: File paths printed in stack trace are where Python was built???
Actually, if you to get an error from a module built with zipimport it points to where that module was built as well.

Re: Problems running on hp duo Pentium R processor
If they are running standard Win XP (Home or Pro), as opposed to 64-bit Win XP, then whether or not the CPU supports the IA64 instruction set really doesn't matter. As far as I know every Intel Core2 and Pentium Dual-Core CPU since ~ 2006 has supported 64bit instructions, even the Atom is 64bit. Also, the "R" is for Registered Trademark (of Pentium), it's not part of the name/model (http://ark.intel.com/cpu.aspx?groupId=33925).

Re: Python's popularity
Python has it's place, usually getting things done, rather than being flashy. For example, while Java is still the "Enterprise King", both the leading application servers (Weblogic and Websphere) adopted Jython as their internal scripting language last year (or was it 2006?). It's used heavily for internal game scripting (Eve Online uses it very heavily (specifically Stackless), as does BF 2142). I don't know if in fact Python is the 3rd most popular language, but I would not be surprised by it passing up other high level scripting languages like Perl and Ruby.
