What exactly is the filestream_iterator that the FileCacheManager uses?
As I understand it this is a new feature?
For Zope >= 2.7.2, ZPublisher defines an interface, ZPublisher.Iterators.IStreamIterator. An application can return an object implementing this interface to the publisher, instead of a string; if so, the publisher hands it directly to medusa, and frees up the application thread / database connection. medusa will use the iterator to send the response back to the user, without first converting it to a single big string.
That's actually brilliant.
If I understand ExternalFile could benefit from using the IStreamIterator interface instead of RESPONSE.write?
For instance, for someone that don't want to store blobs
in the database temporarily :-)
