2013-11-10Cleanup code using forward declarations.Brandon Dahler
Use misc methods of avoiding unnecesary header includes. Replace int typedefs with int##_t from stdint.h. Replace PRI64[xdu] with PRI[xdu]64 from inttypes.h. Normalize QT_VERSION ifs where possible. Resolve some indirect dependencies as direct ones. Remove extern declarations from .cpp files.

2013-10-29-fuzzmessagestest=N : randomly corrupt 1-of-N sent messagesGavin Andresen
I needed this to test the new "reject" p2p message, but it should be generally useful for fuzz-testing network message handling code.
2013-10-21Adding new "addrlocal" field to RPC getpeerinfo.Josh Lehan
The existing CNode::addrLocal member is revealed to the user, as an address string, similar to the existing "addr" field. Instead of showing garbage or empty string, it simply will not appear in the output if local address not known yet.

2013-10-04Added ping time measurement.Josh Lehan
New RPC "ping" command to request ping. Implemented "pong" message handler. New "pingtime" field in getpeerinfo, to provide results to user. New "pingwait" field, to show pings still in flight, to better see newly lagging peers.

2013-06-19Introduce a CChainParameters singleton class and regtest mode.Mike Hearn
The new class is accessed via the Params() method and holds most things that vary between main, test and regtest networks. The regtest mode has two purposes, one is to run the bitcoind/bitcoinj comparison tool which compares two separate implementations of the Bitcoin protocol looking for divergence. The other is that when run, you get a local node which can mine a single block instantly, which is highly convenient for testing apps during development as there's no need to wait 10 minutes for a block on the testnet.

2013-06-05Removed net.cpp's dependency on init.h.Eric Lombrozo
Added explicit include of main.h in init.cpp, changed include of init.h to include of main.h in net.cpp. Added function registration for net.cpp in init.cpp's network initialization. Removed protocol.cpp's dependency on main.h. TODO: Remove main.h include in net.cpp.

2013-05-01Do not kill connections on recv buffer overflowPieter Wuille
Instead of killing a connection when the receive buffer overflows, just temporarily halt receiving before that happens. Also, no matter what, always allow at least one full message in the receive buffer (otherwise blocks larger than the configured buffer size would pause indefinitely).
2013-04-29Try to increase file descriptor rlimit if necessaryPieter Wuille
As the default can be too low, especially on OSX.
2013-04-28move WSAStartup to initWladimir J. van der Laan
WSAStartup should be called before using any other socket functions. BindListenPort is not called if not listening. Closes #2585.

2013-04-07Make sure we always have a node to do IBD fromPieter Wuille
This introduces the concept of the 'sync node', which is the one we asked for missing blocks. In case the sync node goes away, a new one will be selected. For now, the heuristic is very simple, but it can easily be extended later to add better policies.

2013-04-04Drop release times for CNodePieter Wuille
It seems there were two mechanisms for assessing whether a CNode was still in use: a refcount and a release timestamp. The latter seems to have been there for a long time, as a safety mechanism. However, this timer also keeps CNode objects alive for far longer than necessary after disconnects, potentially opening up a DoS window. This commit removes the timestamp-based mechanism, and replaces it with an assert(nRefCount >= 0), to verify that the refcounting is indeed correctly working.

2013-04-03Port Thread* methods to boost::thread_groupGavin Andresen
2013-04-03Rename util.h Sleep --> MilliSleepGavin Andresen
Two reasons for this change: 1. Need to always use boost::thread's sleep, even on Windows, so the sleeps can be interrupted (prior code used Windows' built-in Sleep). 2. I always forgot what units the old Sleep took.
2013-04-03Shutdown cleanup prep-workGavin Andresen
Create a boost::thread_group object at the qt/bitcoind main-loop level that will hold pointers to all the main-loop threads. This will replace the vnThreadsRunning[] array. For testing, ported the BitcoinMiner threads to use its own boost::thread_group.

2013-04-01Move mapAlreadyAskedFor to limitedmapMatt Corallo
This will result in re-requesting invs if we are under heavy inv load, however as long as we get no more than 16,000 invs in two minutes, this should have no effect on runtime behavior.

2013-03-29Use per-message send buffer, rather than per connectionPieter Wuille
2013-03-29Some fixes to CNetMessage processingPieter Wuille
* Change CNode::vRecvMsg to be a deque instead of a vector (less copying) * Make sure to acquire cs_vRecvMsg in CNode::CloseSocketDisconnect (as it may be called without that lock).
2013-03-29P2P: improve RX/TX flow controlJeff Garzik
1) "optimistic write": Push each message to kernel socket buffer immediately. 2) If there is write data at select time, that implies send() blocked during optimistic write. Drain write queue, before receiving any more messages. This avoids needlessly queueing received data, if the remote peer is not themselves receiving data. Result: write buffer (and thus memory usage) is kept small, DoS potential is slightly lower, and TCP flow control signalling is properly utilized. The kernel will queue data into the socket buffer, then signal the remote peer to stop sending data, until we resume reading again.
