samrushing / caesure Goto Github PK

Just wonder if this is a full node or you still rely on a bitcoind node running in order to get to use this.
Whats the difference between this project and pycoind?

On startup I get plenty of blocks, but this peters out after a few minutes. I'm still getting INV and ADDR messages, however.

I'm seeing multi-second latency warnings in feed_block... at first I thought it was disk I/O, but now I think there's a serious problem with the txmap::outpoints class... need to experiment with replacing that vector with a set. The reason I say this is that I can see a series of 20-30 blocks fly by, each taking a fraction of a second. Then a block comes in that takes several seconds to process.

Thanks. EOM

I installed cython using sudo apt-get install cython. Any suggestions?

"setup.py install" ends up getting the shared libraries generated by cython and the contents of caesure/ installed into sys.path nicely, but a workaround is needed to run bitcoin.py from the tree:
