2006-03-27 Tatsuhiro Tsujikawa <tujikawa at rednoah dot com>

	* configure.in: Added gnutls support. Added several CPP macros.
	* m4/openssl.m4: Added.
	* src/SocketCore.{h,cc}: Drop const quarifier from writeData(),
	readData(), peekData(). Added gnutls support.
	* src/HttpDownloadCommand.cc: Removed SleepCommand.h
	* src/TrackerWatcherCommand.{h,cc}: Added. This command creates
	TrackerInitCommand periodicaly(TorrentMan::minInterval).
	* src/TorrentMan.cc: Remove downloadedSize == 0 check from 
save().
	Instead, added a check for whether setup method has executed
	successfully.
	* src/TorrentMan.h: Added member vaiable setupComplete. Updated
	DEFAULT_ANNOUNCE_INTERVAL and DEFAULT_ANNOUNCE_MIN_INTERVAL to 
300.
	* src/Makefile.am: Updated.
	* src/messageDigest.h: Added. This is a macro calculating SHA1 
digest
	using whether OpenSSL or gcrypt, depending on the result of 
configure
	script.
	* src/ShaVisitor.{h,cc}: Removed direct	dependency on OpenSSL by 
using
	messageDigest.h. 
	* src/TorrentAutoSaveCommand.h: Removed unused variable cuid.
	* src/PeerListenCommand.cc: Added log about port binded 
successfully.
	Fixed memory leak.
	* src/main.cc: Added gnutls support. Replaced LIB_SSL with
	ENABLE_BITTORRENT where they are not related to OpenSSL but 
BitTorrent.
	Removed instantiation of TrackerInitCommand. Instead,
	TrackerWatcherCommand is instantiated and pushed to the command 
queue.
	* src/InitiateConnectionCommandFactory.cc: Replaced HAVE_LIBSSL 
with
	ENABLE_SSL.
	* src/Request.cc: Replaced HAVE_LIBSSL with ENABLE_SSL.
	* src/RequestSlotMan.cc:
	(deleteCompletedRequestSlot)
	If a piece is already acquired by another command, delete the 
request
	slots for the piece.
	* src/TrackerUpdateCommand.cc:
	(execute)
	Changed log level of MSG_TRACKER_WARNING_MESSAGE from info to 
warn.
	Added a check whether peer list is null.
	Fixed the bug that causes sending completed event to the tracker
	several times.
	* src/TrackerInitCommand.cc:
	(execute)
	Fixed the bug that causes sending completed event to the tracker
	several times.
	* src/AbstractDiskWriter.{h,cc}: Removed direct dependency on 
OpenSSL
	by using messageDigest.h.
	
	
2006-03-26  Tatsuhiro Tsujikawa  <tujikawa at rednoah dot com>

	* PeerConnection.cc: Replaced log message "keep-alive" with
	"keep alive".
	* PeerInteractionCommand.{h,cc}: Close connection if peer is 
choking
	localhost long time.
	* TorrentMan.cc: When adding new peer with duplicate = true, if 
the
	number of peer list is equal to or grater than MAX_PEER_LIST, 
delete
	at most 100 failure entry from the list. If with duplicate = 
false,
	MAX_PEER_LIST is not checked.
	* PeerListenCommand.cc: Fixed the argument order of log message.

2006-03-25  Tatsuhiro Tsujikawa  <tujikawa at rednoah dot com>

	* Logger.h: Moved enum LEVEL from SimpleLogger.h to here.
	Added warn().
	* SimpleLogger.h: Moved enum LEVEL to Logger.h.
	Implemented warn().
	Defined 2 macros(WRITE_LOG, WRITE_LOG_EX) to avoid duplicated 
code.
