Using a CouchDB server we have a different database object potentially for
every request.
We already set that db in the request object to make it easy to pass it
around form our django app, however it would be nice if I could set it once
in the API and automatically fetch it from there.
Django makes your life a lot easier in many ways, but you still need some
time to learn it.
The task you're trying it's not trivial though, depending on your
experience it might take a while with any library/framework..

Thanks a lot, that makes a lot of sense.. I haven't given this detail
before because I didn't write this code, and I forgot that there were
threads involved completely, I'm just trying to help to fix this bug.
Your explanation makes a lot of sense,

I have some complex input to parse (with regexps), and I would like to
create nice objects directy from them.
The re module doesn't of course try to conver to any type, so I was
playing around to see if it's worth do something as below, where I
assign a constructor to every regexp and build an

I would also like to avoid this in general, but we have many
subprocesses to launch and some of them might take weeks, so we need
to have a process which is always running, because there is never a
point in time where we can just say let's

That would probably be correct. However, I still think you may be
fighting against the language instead of playing to its strengths.
I've never fiddled with sys.modules like that, but I know some have,

I have some long running processes that do very long simulations which
at the end need to write things on a database.
At the moment sometimes there are network problems and we end up with
half the data on the database.
The half-data problem is probably solved easily with sessions and

Since you know the content of what the sql code is, why not just build
the sql file(s) needed and store them so that in case of a burp you can
just execute the code file. If you don't know the exact sql code, dump
it to a file as the statements are

Now I found a way to reload the code successfully, as you can see from
