Does anyone know if the 2.0.5 windows release of Plone includes ZEO?

Do you have installed it? Then see whether the "Zope" part contains the folder "ZEO" (usually in "lib/python"). If it does, then it contains "ZEO".

Also does Zope 2.8 for linux have ZEO as standard.

Yes, I think so. Again: install and check whether the "ZEO" part is there.

Finally, if you don't run ZEO does this mean that Zope can only handle one request at a time?

No. It only does mean that a single process can access your ZODB data. A standard Zope process has 4 worker threads that can execute requests in parallel. Note, however, that even when you run on a multi-processor maschine, the various Python threads may not be able to truely run in parallel (a single process allows only a single thread to execute Python code; other threads may wait on something external or execute non Python (e.g. C) code, but they cannot execute Python code truely in parallel). -- Dieter

Can I contribute a small TabindexIterator class for ZTUtils. It is not big, but handy for generating tabindex values in a site. The current Iterator class available was not meant to do this but this is. I think this could be added to Iterators.py It seems better to incorporate something like this in ZTUtils than making a site tool to do this. It only provides one method next() and takes a sequence. If you want your tabindex to start at 500 and go no further than 599, you just give it range(500,600) and stops iterating. For for 0 to n - just use range(n). It could always pass after iteration stops but I think it is better to raise exception so you can modify your sequence, if necessary. class TabindexIterator: """ Tabindex iterator class """ __allow_access_to_unprotected_subobjects__ = 1 def __init__(self, seq): self.iter = seq.__iter__() def next(self): try: next = self.iter.next() return next except StopIteration: raise 'Tabindex iterator exhausted.'
