check if file is a symlink
Here is a small piece of code:
import os
from stat import *
filePath = "/home/xyz/symLinkTest"
mode = os.stat(filePat h)[ST_MODE]
print 'Find using os.path : ',os.path.islin k(filePath)
print 'Find using mode :', S_ISLNK(mode)
print 'Is this a regular file : ' S_ISREG(mode)
Output :
---------
Find using os.path : True
Find using mode : False
Is this a regular file : True
File symLinkTest is a symbolic link.
Why S_ISLNK(mode) returns False and S_ISREG(mode) returns True ? 5 3595

Because you are using os.stat() instead of os.lstat().

Do you mean the following is deprecated ? http://docs.python.org/lib/module-stat.html
From the documentation -
S_ISLNK( mode)
Return non-zero if the mode is from a symbolic link.
Thanks

No, it means that os.stat follows the symbolic link and gives stat
information for the file that the symbolic link points to, which is
*not* a symbolic link. Like the documentation for lstat says: "Like
stat(), but do not follow symbolic links." But why not just use
os.path.islink?

As that page states, that's a function used to interpret a mode flag
returned by os.stat, os.fstat, or os.lstat. It obviously won't give you
the result you're looking for if you use a stat function that *follows*
symbolic links.

Thank you Fredrick and Miles,
stat() is on the actual file and not on the symlink. That explains.

Running Windows 2003 Server on an intranet.
A web is configured with an anonymous access account that is a domain account that has been granted the desired access to a file on another server in the domain.
An asp page in the web attempts to open (or any other access) the remote file and fails.
Auditing is enabled on the remote system and for the file in question but no access denied records are being
recorded.

Hi all,
I am not a developer, but I work with several and am posting this for
them. We are trying to determine whether it is possible to check the
size of a file before a user uploads it.
Everything I've read suggests that this is impossible (or at least very
difficult) in PHP, and this makes sense for a server-side language.
What gives me pause, however, is the fact that when a user tries to
upload a file larger than the max file...

I am trying to do a FTP file upload which works fine on my localhost but on

specific cause of the failure. In both cases the file is being transmitted

If I participate in a forum that doesn't have any way to watch threads
or any type of RSS, I could get the filesize of the thread I want to
watch. When the filesize changes, I know there is a new post. Are
there any reasons why this won't work?
If the above will work, how is it different from using RSS? Or can RSS
support just a regular page (no XML for RSS available)?
Thanks,

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

For most users, this new feature is actually very convenient. If you want to control the update process,...
