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.

- in OpenNetworkConnection we have a FindNode call, which gets a const char*, wheras we only have defined a FindNode for std::string
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)

This negates the need for CAddress here at all

No need to define it for every CAddress, as it's memory only anyway.

2015-02-08Sanitize command strings before logging them.Gregory Maxwell
Normally bitcoin core does not display any network originated strings without sanitizing or hex encoding. This wasn't done for strcommand in many places. This could be used to play havoc with a terminal displaying the logs, especially with printtoconsole in use. Thanks to Evil-Knievel for reporting this issue.
