Yeah, I know. Send it to the list. Anyway, I regularly end up
forgetting to change the permissions on Cache, Sessions, Logs, and
ErrorMsgs. Invariably, I get this traceback in the error_log:
Traceback (most recent call last):
File "/var/opt/sb/m2tmp/webware/WebKit/AppServer.py", line 184, in
loadPlugIn
willNotLoadReason = plugIn.load()
File "/var/opt/sb/m2tmp/webware/WebKit/PlugIn.py", line 72, in load
os.mkdir(cacheDir)
OSError: [Errno 13] Permission denied:
'/var/opt/sb/m2tmp/appdir/Cache/MiddleKit'
ERROR: Plug-in /var/opt/sb/m2tmp/webware/MiddleKit raised exception.

self.error('Plug-in %s raised exception.' % path)
File "/var/opt/sb/m2tmp/webware/WebKit/AppServer.py", line 279, in
error sys.exit(1) # @@ 2000-05-29 ce: Doesn't work. Perhaps because

[Fri Dec 14 03:55:19 2001] [error] [client 127.0.0.1] Premature end of
script headers: /rootdir/var/opt/sb/m2tmp/cgi-bin/OneShot.cgi
Now, note that, in addition to the basic barf, it's barfing a second
time because it can't write the barf to ErrorMsgs. My suggestion is
twofold:
1) Make sure you dump the exception to the browser regardless of
whether or not you can write it to ErrorMsgs / Logs
2) When you detect "permission denied" for any of those four
directories, give an explicit error page that says "hey, dummy, go
set the permissions correctly on those dirs".
