Fixed the bug that prefixLength of split bucket which doesn't
include
local node ID is incremented.
* src/DHTBucket.cc
* src/DHTBucket.h
* test/DHTBucketTest.cc
Rewritten SharedHandle. Now copy constructor taking raw pointer
has
keyword explicit and SharedHandle's default constructor
initializes
its internal obj to null, old implementation initializes it
using
obj's default constructor.
To assign null, write SharedHandle<T> x(...); x.reset();
TODO: test/SharedHandleTest.cc needs more tests.
* src/SharedHandle.h
Fixed high memory footprint when DHT is enabled.
This is not a memory leak, but DHTReplaceNodeTask is more frequently
queued than it is processed and the queue is getting longer. As a
consequence, momory usage is increased.
As for a fix, instead of issuing DHTReplaceNodeTask, I've implemented
replacement cache in DHTBucket which is described in Kademlia paper.
* src/DHTRoutingTable.cc (addNode): Removed the issuing of
DHTReplaceNodeTask.
* src/DHTBucket.{h, cc}
(cacheNode): New function.
(getCachedNodes): New function.
(dropNode): Push back cached node to _nodes.
* test/DHTBucketTest.cc
(testCacheNode): New test
(testDropNode): New test
Added DHT functionality, compatible with mainline.
DHT is disabled by default. To enable it, give --enable-dht to
aria2c.
You may need to specify entry point to DHT network using
--dht-entry-point. DHT uses UDP port to listen incoming message.
Use --dht-listen-port to specify port number. Make sure that
your
firewall configuration can pass through UDP traffic to the port.
The routing table is saved in $HOME/.aria2/dht.dat.
* src/DHT*
* src/BNode.{h, cc}
* src/PeerInteractionCommand.cc: enable DHT functionality for a
particular torrent.
* src/Data.cc: Rewritten ctor.
* src/OptionHandlerFactory.cc: Added --enable-dht,
--dht-listen-port,
--dht-entry-point.
* src/DefaultBtInteractive.cc: Send port message if dht is
enabled.
* src/RequestGroup.cc: Initialize DHT functionality. When
download
ends, remove BtContext from DHTPeerAnnounceStorage.
* src/BtPortMessage.{h, cc}: Rewritten.
* src/message.h
* src/OptionHandlerImpl.cc
* src/option_processing.cc: Added --enable-dht,
--dht-listen-port,
--dht-entry-point.

Create DHT commands.
