Re: [Webware-discuss] Possible CGIWrapper error when usingApache under Windows ME

[haaserd <ha...@ya...>]

Thanks, that fixed the problem.

On to the next one:  I had to put this patch in around line 386 of the
"serve" function before I could import any modules out of the directory that
holds my .py scripts.

  if self.setting('ChangeDir'):
   #rdh 6/13/1
   sys.path.append(os.path.split(self._scriptPathname)[0])
   #end rdh
   origDir = os.getcwd()
   os.chdir(os.path.split(self._scriptPathname)[0])

It seems the point of doing the os.chdir is to allow the script being
executed to import additional modules out of its own directory.  This
doesn't seem to work with W/me after an execfile.  I posted the following
under the title "os.chdir() and import" on comp.lang.python earlier today,
no response yet:

"Under Windows and Python 2.1, I am sometimes able to use an
os.chdir('xxx') and then follow this with an import command
for a module located in the 'xxx' directory.

However, it seems that when the module doing the
os.chdir('xxx') and import-ing is executing because of an
execfile() command, this technique doesn't work and an
import error occurs.

A search of the documentation seems to indicate that the
import search path is determined only by the value of
sys.path ("...It [import] generally involves searching for a
``built-in'' module with the given name and then searching a
list of locations given as sys.path." -- Python Reference
Manual 6.11).  I think "generally" here may refer to the
unique processing used for packages, but...?

Can someone clear this up for me?  Should sys.path always be
modified instead of using os.chdir?"
