2006-06-12 Tatsuhiro Tsujikawa <tujikawa at rednoah dot com> To add Time class which represents a specific instant in time and its precision is microseconds. Time checking procedures were rewritten using this object. * src/Time.h: New class. * src/Time.cc: New class. * src/AbstractCommand.h (updateCheckPoint): Removed. (isTimeoutDetected): Removed. (checkPoint): Changed the type to Time. (timeout): New variable. (setTimeout): New function. * src/AbstractCommand.cc (AbstractCommand): Removed the initialization of checkPoint. Added the initialization of timeout. (updateCheckPoint): Removed. (isTimeoutDetected): Removed. (execute): Use checkPoint.reset() and checkPoint.elapsed(). * src/PeerChokeCommand.h (checkPoint): Changed the type to Time. * src/PeerChokeCommand.cc (PeerChokeCommand): Removed the initialization of checkPoint. (execute): Rewritten using Time object. * src/TrackerWatcherCommand.h (checkPoint): Changed the type to Time. * src/TrackerWatcherCommand.cc (TrackerWatcherCommand): Removed the initialization of checkPoint. (execute): Rewritten. * src/ConsoleDownloadEngine.h (cp): Changed the type to Time. (startup): Changed the type to Time. * src/ConsoleDownloadEngine.cc (initStatistics): Use cp.reset(), startup.reset(). (calculateStatistics): Rewritten using Time object. * src/PeerAbstractCommand.h (updateCheckPoint): Removed. (isTimeoutDetected): Removed. (checkPoint): Changed the type to Time. * src/PeerAbstractCommand.cc (PeerAbstractCommand): Removed the initialization of checkPoint. (updateCheckPoint): Removed. (isTimeoutDetected): Removed. (execute): Use checkPoint.reset() and checkPoint.elapsed(). * src/PeerInteractionCommand.cc (PeerInteractionCommand): Removed the initializations of struct timeval variables. * src/PeerInteractionCommand.h (keepAliveCheckPoint): Changed the type to Time. (chokeCheckPoint): Changed the type to Time. (freqCheckPoint): Changed the type to Time. (haveCheckTime): Changed the type to Time. * src/PeerInteractionCommand.cc (executeInternal): Rewritten using Time object. (detectMessageFlooding): Rewritten using Time object. (checkLongTimePeerChoking): Rewritten using Time object. (sendKeepAlive): Rewritten using Time object. (checkHave): Rewritten using Time object. * src/SleepCommand.h (checkPoint): Changed the type to Time. * src/SleepCommand.cc (SleepCommand): Removed the initialization of checkPoint. (execute): Rewritten using Time object. * src/TorrentAutoSaveCommand.h (checkPoint): Changed the type to Time. * src/TorrentAutoSaveCommand.cc (TorrentAutoSaveCommand): Removed the initialization of checkPoint. (execute): Rewritten. * src/DownloadCommand.h (sw): Changed the type to Time. * src/DownloadCommand.cc (DownloadCommand): Removed the initialization of sw. (executeInternal): Rewritten. * src/RequestSlot.h (dispatchedTime): Changed the type to Time. * src/RequestSlot.cc (RequestSlot): Removed the call to setDispatchedTime(). (setDispatchedTime): Rewirtten. (isTimeout): Rewritten. (getLatencyInMillis): Rewritten. * src/TorrentDownloadEngine.h (cp): Changed the type to Time[2]. (startup): Changed the type to Time. * src/TorrentDownloadEngine.cc (initStatistics): Rewritten. (calculateStatistics): Rewritten. * src/DownloadEngine.cc (run): Rewritten. To detect all attempts to connect to the tracker are failed: * src/AbstractCommand.cc (execute): Increment e->segmentMan->errors if a command aborted. * src/SegmentMan.h (errors): New variable. * src/SegmentMan.cc (SegmentMan): Added the initialization of errors. (init): Added the initialization of errors. * src/TrackerWatcherCommand.cc (execute): If e->segmentMan->errors > 0 then assume that the tracker request was failed. To handle snubbed peers: * src/PeerChokeCommand.cc (optUnchokingPeer): Snubbed peers don't get unchoked. (execute): Snubbed peers don't get unchoked. * src/PeerInteraction.h (REQUEST_TIME_OUT): Changed the value from 120 to 60. * src/PeerInteraction.cc (checkRequestSlot): A peer get marked as "snubbed" if it doesn't send back the requested 16k block in 60 seconds. * src/PieceMessage.cc (receivedAction): A peer's snubbed state is cleard if it sends the requested 16k block in 60 seconds. * src/Peer.h (snubbing): New variable. * src/Peer.cc (resetStatus): Added snubbed = false. To fix the bug that causes have message is not sent: * src/PeerInteractionCommand.cc (~PeerInteractionCommand): Removed e->torrentMan->unadvertisePiece(). (FLOODING_CHECK_INTERVAL): New definition(temporal). (detectMessageFlooding): Use FLOODING_CHECK_INTERVAL. * src/TorrentMan.h (HaveEntry): New class. (advertisePiece): Rewritten. (getAdvertisedPieceIndexes): Rewritten. (Haves): Changed the type. (getAdvertisedPieceIndexes): Added an argument. Others: * src/TorrentMan.h (DEFAULT_ANNOUNCE_INTERVAL): Changed the value to 1800. (DEFAULT_ANNOUNCE_MIN_INTERVAL): Changed the value to 1800. * src/TorrentMan.cc (getPeer): Don't check the number of connections here. (setupInternal1): Changed peerId. * src/PeerInteractionCommand.h (KEEP_ALIVE_INTERVAL): New definition. (sendKeepAlive): Use KEEP_ALIVE_INTERVAL. * src/main.cc (main): SA_ONESHOT was replaced with SA_RESETHAND. * src/DownloadEngine.h: Removed unnecessary header includes.
