|

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.

o Major bugfixes (hidden services):
|
||||
- When closing an introduction circuit that was opened in parallel with
|
||||
others,
|
||||
don't mark the introduction point as unreachable. Previously, the
|
||||
first successful connection to an introduction point would make
|
||||
the other introduction points get marked as having timed out.
|
||||
Fixes bug 13698; bugfix on 0.0.6rc2.
