Simpler solutions make life simpler... (Abandoning chaining in favour of updating)


As mentioned a while ago, I was trying to build a chaining mechanism into TwistedSNMP's OIDStore mechanism, the idea being that you could mix-and-match OIDStores so that you could compose test-cases readily from pre-built OIDStore fragments.

Problem was that the code became hideous. It's just a graph-traversal algorithm, but the code wasn't ...

Couldn't give away the Molé (So I just didn't make it tonight...)


Tim, Shiva, Shademan, Lisa, Golnar, and Shane were all unavailable, Natasha had already eaten, and Krysta couldn't get past the idea of chocolate and chicken together, so I had no-one for whom to cook (well, turns out I would have had Rosey, but I didn't know that). Anyway, guess I'll cook it ...

Chaining OIDStores in TwistedSNMP (Today's little side project...)


TwistedSNMP has a mechanism called an OIDStore, which allows you to define the values to be returned from a (server-side) agent. At the moment, these are quite simplistic creations, basically either a bisect-sorted list or a BSDDB btree database (the OIDStore must be ordered, which is why a simple dictionary wouldn't work).

That works ...
