Summary: os.path.exists("file/") failure on Solaris 9
Initial Comment:
Solaris 9 and earlier fail to conform to POSIX, in that
stat("FILE/") succeeds even when FILE is not a directory.
POSIX says that in this case it should fail. This problem causes
os.path.exists("FILE/") to succeed when it should fail, which makes it harder
to write portable Python code. One of my students ran into this problem when
doing a Django-based project: his code ran fine on his Linux box, but failed
when he attempted to run it on the Solaris 8 server that is the standard
platform for our students.
To reproduce the problem, on Solaris 8 (or 9):
$ touch file
$ ls -l file
-rw-rw-r-- 1 eggert csfac 0 Dec 7 14:19 file
$ python
Python 2.5 (r25:51908, Dec 7 2006, 13:14:10)
[GCC 4.1.1] on sunos5
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.path.exists("file/")
True
It should be False.
I'll attach a patch that works around the problem at
run-time. If you prefer something that tests for it
at compile time please let me know.

OK, I'll attach a revised patch that uses a configure test to check for
this bug.

I think it would be sufficient to put a #ifdef <solaris 9> ... #endif
around the additional check. We don't want to make all platforms do extra
system calls in order to avoid a Solaris 9 bug. Or you could write a
configure test to check for this bug, but that's more complicated a task.
