* Introduce a CChainParameters singleton class and regtest mode.Mike Hearn2013-06-191-130/+20
| | | | | | | | | | | | | 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.

* Do not kill connections on recv buffer overflowPieter Wuille2013-05-011-15/+30
| | | | | | | | 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).

| | | | | | | WSAStartup should be called before using any other socket functions. BindListenPort is not called if not listening. Closes #2585.

| * Make sure we always have a node to do IBD fromPieter Wuille2013-04-071-7/+52
| | | | | | | | | | | | | | | | | | 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.

| * Drop release times for CNodePieter Wuille2013-04-041-11/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | 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.

* | Rename util.h Sleep --> MilliSleepGavin Andresen2013-04-031-17/+17
| | | | | | | | | | | | | | | | 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.
* | Shutdown cleanup prep-workGavin Andresen2013-04-031-1/+1
| | | | | | | | | | | | | | | | | | | | 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.

* | P2P: improve RX/TX flow controlJeff Garzik2013-03-291-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | P2P: parse network datastream into header/data components in socket threadJeff Garzik2013-03-291-13/+83
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replaces CNode::vRecv buffer with a vector of CNetMessage's. This simplifies ProcessMessages() and eliminates several redundant data copies. Overview: * socket thread now parses incoming message datastream into header/data components, as encapsulated by CNetMessage * socket thread adds each CNetMessage to a vector inside CNode * message thread (ProcessMessages) iterates through CNode's CNetMessage vector Message parsing is made more strict: * Socket is disconnected, if message larger than MAX_SIZE or if CMessageHeader deserialization fails (latter is impossible?). Previously, code would simply eat garbage data all day long. * Socket is disconnected, if we fail to find pchMessageStart. We do not search through garbage, to find pchMessageStart. Each message must begin precisely after the last message ends. ProcessMessages() always processes a complete message, and is more efficient: * buffer is always precisely sized, using CDataStream::resize(), rather than progressively sized in 64k chunks. More efficient for large messages like "block". * whole-buffer memory copy eliminated (vRecv -> vMsg) * other buffer-shifting memory copies eliminated (vRecv.insert, vRecv.erase)
