So my only question remaining, for which I've not yet +reviewed the code, is: what is the behaviour under assault from lots +of new incoming TCP connections? One very common problem with +threaded TCP servers is blindly creating new threads without any +filtering or checking of incoming connections, thereby quickly +reaching thread limits, possibly causing other parts of the program to +fail. + +Any amount of RPC request volume, miner or not, sent to the present +implementation winds up using a lot of socket resources due to the +constant disconnect/reconnect demanded of the current HTTP/1.0 code. +This patch addresses that key issue, providing positive impact for all +production bitcoin sites using RPC. + +Miners are hitting these problems now, and Gavin's right that mainnet +miners are a small portion of the total population, but our RPC server +implementation really is bloody awful at present. Reliable, +production TCP servers use either threads or async I/O, or a +combination of both (thread pool + async I/O =3D=3D win). Deploying +HTTP/1.1 persistent connections will make a positive impact at any +site heavily using RPC. + + +>> =A0 bugfix_CreateThread_leak + +Did I leave something out, when merging + + commit 67ed7d9d4929d8fe1c5f976c184c72dff02d83b7 + Author: JoelKatz <DavidJoelSchwartz@GMail.com> + Date: Mon Jul 25 15:06:45 2011 -0700 + +? + + +>> =A0 getwork_dedupe (original branch for my bugfix) + +I think we need this, but have not yet reviewed/thought about it. + +>> =A0 gitignore (ignore some common misc files) + +Sounds nice to have. + + Jeff + + +P.S.
