Tor 0.2.6.2-alpha is the second alpha release in the 0.2.6.x series.
|
|
|
|
|
|
o Major features (relay, infrastructure):
|
|
|
-
|
|
|
- - Completely revision of the code that relays use to decide which cell to
|
|
|
- send next. Formerly, we selected the best circuit to write on each
|
|
|
- channel, but we didn't select among channels in any sophisticated way.
|
|
|
- Now, we choose the best circuits globally from among those whose
|
|
|
- channels are ready to deliver traffic.
|
|
|
-
|
|
|
- This patch implements a new inter-cmux comparison API, a global high/low
|
|
|
- watermark mechanism and a global scheduler loop for transmission
|
|
|
- prioritization across all channels as well as among circuits on
|
|
|
- one channel. This schedule is currently tuned to (tolerantly)
|
|
|
- avoid making changes in the current network performance, but it
|
|
|
- should form the basis for major circuit performance increases.
|
|
|
- Code by Andrea; tuning by Rob Jansen; implements ticket 9262.

o Major features (hidden services):
|
|
|
- Add a HiddenServiceStatistics option that allows Tor relays to
|
|
|
- gather and publish statistics the overall size and volume of hidden
|
|
|
- service usage.
|
|
|
- Specifically, when this option is turned on, an HSDir will publish
|
|
|
- an approximate number of hidden services that have published
|
|
|
- descriptors to it the past 24 hours. Also, if a relay has acted as
|
|
|
- a hidden service rendezvous point, it will publish the approximate
|
|
|
- amount of rendezvous cells it has relayed the past 24 hours. The
|
|
|
- statistics themselves are obfuscated so that the exact values
|
|
|
- cannot be derived. For more details see proposal 238, "Better
|
|
|
- hidden service stats from Tor relays". This feature is currently
|
|
|
- disabled by default. Implements feature 13192.

|
