forked from I2P_Developers/i2p.i2p
b2f0d17e94
* Added a pool of PRNGs using a different synchronization technique,
hopefully sufficient to work around IBM's PRNG bugs until we get our
own Fortuna.
* In the streaming lib, don't jack up the RTT on NACK, and have the window
size bound the not-yet-ready messages to the peer, not the unacked
message count (not sure yet whether this is worthwile).
* Many additions to the messageHistory log.
* Handle out of order tunnel fragment delivery (not an issue on the live
net with TCP, but critical with UDP).
and for udp stuff:
* implemented tcp-esque rto code in the udp transport
* make sure we don't ACK too many messages at once
* transmit fragments in a simple (nonrandom) order so that we can more easily
adjust timeouts/etc.
* let the active outbound pool grow dynamically if there are outbound slots to
spare
* use a simple decaying bloom filter at the UDP level to drop duplicate resent
packets.
