From 33e28c9948336784324cf5c7248ce608b93dbfde Mon Sep 17 00:00:00 2001 From: Giel van Schijndel Date: Thu, 11 Aug 2011 18:40:12 +0200 Subject: Move CAddress to protocol.[ch]pp This commit does *not* and should not modify *any* code, it only moves it from net.h and splits it across protocol.cpp and protocol.hpp. Signed-off-by: Giel van Schijndel --- src/net.h | 225 -------------------------------------------------------------- 1 file changed, 225 deletions(-) (limited to 'src/net.h') diff --git a/src/net.h b/src/net.h index 7a4706d53b..66f3949b86 100644 --- a/src/net.h +++ b/src/net.h @@ -16,7 +16,6 @@ #include "protocol.h" -class CAddress; class CAddrDB; class CInv; class CRequestTracker; @@ -29,15 +28,7 @@ extern int nConnectTimeout; inline unsigned int ReceiveBufferSize() { return 1000*GetArg("-maxreceivebuffer", 10*1000); } inline unsigned int SendBufferSize() { return 1000*GetArg("-maxsendbuffer", 10*1000); } -inline unsigned short GetDefaultPort() { return fTestNet ? 18333 : 8333; } static const unsigned int PUBLISH_HOPS = 5; -enum -{ - NODE_NETWORK = (1 << 0), -}; - - - bool ConnectSocket(const CAddress& addrConnect, SOCKET& hSocketRet, int nTimeout=nConnectTimeout); bool Lookup(const char *pszName, std::vector& vaddr, int nServices, int nMaxSolutions, bool fAllowLookup = false, int portDefault = 0, bool fAllowPort = false); @@ -55,222 +46,6 @@ bool BindListenPort(std::string& strError=REF(std::string())); void StartNode(void* parg); bool StopNode(); -static const unsigned char pchIPv4[12] = { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0xff, 0xff }; - -class CAddress -{ -public: - uint64 nServices; - unsigned char pchReserved[12]; - unsigned int ip; - unsigned short port; - - // disk and network only - unsigned int nTime; - - // memory only - unsigned int nLastTry; - - CAddress() - { - Init(); - } - - CAddress(unsigned int ipIn, unsigned short portIn=0, uint64 nServicesIn=NODE_NETWORK) - { - Init(); - ip = ipIn; - port = htons(portIn == 0 ?
