I have been working with repoze.zodbconn (in conjunction with repoze.bfg
and Karl 3) and there have been several times when I wish I could just
insert some WSGI component that does something with the ZODB connection.
- At one point I wanted repoze.who.plugins.zodb to use the same
connection as the application uses. We shouldn't have to set up the
ZODB connection twice on every request. The cost is low but measurable.
- I wanted to create a WSGI logger that watches how many objects are
loaded or stored by the handler for a request.
- Right now, I want to fine-tune the contents of the ZODB cache after
To make tasks like these easier, I would like to add to repoze.zodbconn
a WSGI framework component that opens a ZODB connection, puts that
connection in the WSGI environment, calls the next WSGI app in the
chain, then closes the same ZODB connection on the way out. I intend to
add it myself, but I would like to hear any feedback the group might
have before I do it.
