2005-02-20 jrandom * Allow the streaming lib resend frequency to drop down to 20s as the minimum, so that up to 2 retries can get sent on an http request. * Add further limits to failsafe tunnels. * Keep exploratory and client tunnel testing and building stats separate. * Only use the 60s period for throttling tunnel requests due to transient network overload. * Rebuild tunnels earlier (1-3m before expiration, by default) * Cache the next hop's routerInfo for participating tunnels so that the tunnel participation doesn't depend on the netDb. * Fixed a long standing bug in the streaming lib where we wouldn't always unchoke messages when the window size grows. * Make sure the window size never reaches 0 (duh)

// tunnel depth variance
2005-02-22 jrandom * Adjusted (and fixed...) the timestamper change detection * Deal with a rare reordering bug at the beginning of a stream (so we don't drop it unnecessarily) * Cleaned up some dropped message handling in the router * Reduced job queue churn when dealing with a large number of tunnels by sharing an expiration job * Keep a separate list of the most recent CRIT messages (shown on the logs.jsp). This way they don't get buried among any other messages. * For clarity, display the tunnel variance config as "Randomization" on the web console. * If lease republishing fails (boo! hiss!) try it again * Actually fix the negative jobLag in the right place (this time) * Allow reseeding when there are less than 10 known peer references * Lots of logging updates.
