If it is a real improvement, 33it will be added to the offical client.. Changing something without knowing 34what all it does can cause great harm to the network if released in mass form.. 35Any mod that changes anything within the Kademlia side will not be allowed to advertise 36there client on the eMule forum.. 37*/ 38 39#ifndef __ROUTING_BIN__ 40#define __ROUTING_BIN__ 41 42#include "Maps.h" 43#include "../../Types.h" 44#include "../kademlia/Defines.h" 45#include "Contact.h" 46 47//////////////////////////////////////// 48namespace Kademlia { 49//////////////////////////////////////// 50 51class CUInt128; 52 53class CRoutingBin 54{ 55public: 56 CRoutingBin() 57 : m_dontDeleteContacts(false) 58 {} 59 ~CRoutingBin(); 60 61 bool AddContact(CContact *contact); 62 void SetAlive(CContact *contact); 63 void SetTCPPort(uint32_t ip, uint16_t port, uint16_t tcpPort); 64 void RemoveContact(CContact *contact, bool noTrackingAdjust = false) { if (!noTrackingAdjust) AdjustGlobalTracking(contact->GetIPAddress(), false); m_entries.remove(contact); } 65 CContact *GetContact(const CUInt128 &id) const throw(); 66 CContact *GetContact(uint32_t ip, uint16_t port, bool tcpPort) const throw(); 67 CContact *GetOldest() const throw() { return m_entries.size() ? m_entries.front() : NULL; } 68 69 uint32_t GetSize() const throw() { return m_entries.size(); } 70 void GetNumContacts(uint32_t& nInOutContacts, uint32_t& nInOutFilteredContacts, uint8_t minVersion) const throw(); 71 uint32_t GetRemaining() const throw() { return K - m_entries.size(); } 72 void GetEntries(ContactList *result, bool emptyFirst = true) const; 73 void GetClosestTo(uint32_t maxType, const CUInt128 &target, uint32_t maxRequired, ContactMap *result, bool emptyFirst = true, bool setInUse = false) const; 74 bool ChangeContactIPAddress(CContact *contact, uint32_t newIP); 75 void PushToBottom(CContact *contact); // puts an existing contact from X to the end of the list 76 CContact *GetRandomContact(uint32_t maxType, uint32_t minKadVersion) const; 77 void SetAllContactsVerified(); 78 bool HasOnlyLANNodes() const throw(); 79 80 static bool CheckGlobalIPLimits(uint32_t ip, uint16_t port); 81 82 bool m_dontDeleteContacts; 83 84protected: 85 static void AdjustGlobalTracking(uint32_t ip, bool increase); 86 87private: 88 ContactList m_entries; 89 90 typedef std::map<uint32_t, uint32_t> GlobalTrackingMap; 91 92 static GlobalTrackingMap s_globalContactIPs; 93 static GlobalTrackingMap s_globalContactSubnets; 94}; 95 96} // End namespace 97 98#endif // __ROUTING_BIN__ 99// File_checked_for_headers 100
