Re: Questions for Vinced about merged mining proxy

I'm going to answer some of these now and some later. We don't know the parent block hash yet. The parent block is what we are trying to find by mining. The ordering of chains is by a pseudo-random generator. I've explained why in another post. Since then someone came up with a better solution whic...

Re: Let's build some merged mining pools!

When the mm proxy is preparing the aux root it has to call buildmerkletree on the parent daemon. The doco for this is very sparse and it isn't clear of this should include the hash from the parent chain or not? if I try it without... e.g. namecoind-mm getauxblock { "target" : "0000000000000000000000...

It appears the last critical update introduced a new bug which if triggered causes a memory leak due the cache flushing thread crashing. If you're using 0.2.8 upgrade is urgently recommended.

Re: [ATT: POOL OPS] PoolServerJ - scalable java pool backend

BTW just noticed you've got usePushPoolCompatibleFormat=false

that means our_result and upstream_result will be set as boolean (or 1,0). Not as 'Y' or 'N' that pushpool uses. If those columns are wrong type this could also cause a problem.
