Update of /cvsroot/freenet/freenet/src/freenet/node/states/FNP
In directory sc8-pr-cvs1:/tmp/cvs-serv25429/src/freenet/node/states/FNP
Modified Files:
NewRequest.java
Log Message:
6295:
If HTL == maxHTL, 50% chance of not decrementing. I believe this converges to an extra
2 hops, somebody please check my math. This provides some plausible deniability when
you send a request at max HTL (perturb runs only on client level...).
?date= now accepts {+,-}{number}{day|week|etc} - relative date/time support in ?date
in fproxy, on the CLI etc (Fields.dateTime).
