2015-10-22Set TCP_NODELAY on P2P sockets.Gregory Maxwell
Nagle appears to be a significant contributor to latency now that the static sleeps are gone. Most of our messages are relatively large compared to IP + TCP so I do not expect this to create enormous overhead. This may also reduce traffic burstyness somewhat.
2015-09-04net: correctly initialize nMinPingUsecTimeWladimir J. van der Laan
`nMinPingUsecTime` was left uninitialized in CNode. The correct initialization for a minimum-until-now is int64_t's max value, so initialize it to that. Thanks @MarcoFalke for noticing.

2015-08-25net: Set SO_REUSEADDR for Windows tooCory Fields
When running the rpc tests in Wine, nodes often fail to listen on localhost due to a stale socket from a previous run. This aligns the behavior with other platforms.

2015-07-27Make CRollingBloomFilter set nTweak for youPeter Todd
While CBloomFilter is usually used with an explicitly set nTweak, CRollingBloomFilter is only used internally. Requiring every caller to set nTweak is error-prone and redundant; better to have the class handle that for you with a high-quality randomness source. Additionally when clearing the filter it makes sense to change nTweak as well to recover from a bad setting, e.g. due to insufficient randomness at initialization, so the clear() method is replaced by a reset() method that sets a new, random, nTweak value.

2015-06-14Added -whiteconnections=<n> optionJosh Lehan
This sets aside a number of connection slots for whitelisted peers, useful for ensuring your local users and miners can always get in, even if your limit on inbound connections has already been reached.

2015-05-14Use CScheduler for net's DumpAddressesGavin Andresen
Instead of starting Yet Another Thread to dump addresses, use CScheduler to do it.
2015-04-30Use ring buffer of set iterators instead of deque of copies in mrusetPieter Wuille
2015-04-30Replace mruset setAddrKnown with CRollingBloomFilter addrKnownGavin Andresen
Use a probabilistic bloom filter to keep track of which addresses we think we have given our peers, instead of a list. This uses much less memory, at the cost of sometimes failing to relay an address to a peer-- worst case if the bloom filter happens to be as full as it gets, 1-in-1,000. Measured memory usage of a full mruset setAddrKnown: 650Kbytes Constant memory usage of CRollingBloomFilter addrKnown: 37Kbytes. This will also help heap fragmentation, because the 37K of storage is allocated when a CNode is created (when a connection to a peer is established) and then there is no per-item-remembered memory allocation. I plan on testing by restarting a full node with an empty peers.dat, running a while with -debug=addrman and -debug=net, and making sure that the 'addr' message traffic out is reasonable. (suggestions for better tests welcome)
