I have managed to reproduce the error by setting SessionUID to an empty
string before calling FSSession. Check for situations where you clear the
REQUEST variables before calling FSSession. In the meantime I will add
some checks on the input values of SessionUID.

I will probably release a fixed version during the weekend if not sooner.

Maybe, a bug in "FSSession.final_commit".

Look at line 208 of "FSSession.py".
I expect some lines before, a filename is constructed
for the above directory and session specific data.
For some reason, the session specific data leads to
an empty filename. Therefore, the operation in
line 208 (probably an "os.rename" or other "os" operation)
gets the directory rather than a file path.

You have two options:

 * analyse, why the session data leads to an empty filename
   (this may be difficult)

 * add a
try: ...
except: pass

   around line 208 and wait for the FSSession author
   to analyse and fix the problem.

[Zope] OSError along with FSSession...

2000-09-05 Thread Chien-Pin Wang


Dear Zope Users:

the same problem several times. Each time it costs me a zope down. I do
really need some help...


 Zope complains an error type "OSError" and throws the error value
saying [Errno 21] Is a directory: '/usr/local/zope/var/FSSession/'
occasionally since a recent upgrade of FSSession product to 0.4.2.
Following that error will be a series of TransactionErrors for each and
every request Zope received. And only a zope restart could help zope
resume its operations. Since this error only comes up occasionally, I'm
completely clueless on solving it. 

 My environment is RedHat Linux 6.2 + Zope 2.1.6. The traceback
information looks like this...

Traceback (innermost last):
  File /usr/local/Zope-2.1.6-src/lib/python/ZPublisher/Publish.py, line

Any help will be very appreciative!
