Changes in version 0.2.2.16-alpha - 2010-09-1?
|
|
|
- o Major features:
|
|
|
- - If you configure your bridge with a known identity fingerprint,
|
|
|
- and the bridge authority is unreachable (as it is in at least
|
|
|
- one country now), fall back to directly requesting the descriptor
|
|
|
- from the bridge. Finishes the feature started in 0.2.0.10-alpha;
|
|
|
- closes bug 1138.

o Major bugfixes (stream-level fairness):
|
|
|
+ - When receiving a circuit-level SENDME for a blocked circuit, try
|
|
|
+ to package cells fairly from all the streams that had previously
|
|
|
+ been blocked on that circuit. Previously, we had started with the
|
|
|
+ oldest stream, and allowed each stream to potentially exhaust
|
|
|
+ the circuit's package window. This gave older streams on any
|
|
|
+ given circuit priority over newer ones. Fixes bug 1937. Detected
|
|
|
+ originally by Camilo Viecco. This bug was introduced before the
|
|
|
+ first Tor release, in svn commit r152: it is the new winner of
|
|
|
+ the longest-lived bug prize.
|
|
|
- When the exit relay got a circuit-level sendme cell, it started
|
|
|
reading on the exit streams, even if had 500 cells queued in the
|
|
|
circuit queue already, so the circuit queue just grew and grew in

Closes bug 1843. Suggested by katmagic.
|
|
|
- When logging a rate-limited warning, we now mention how many messages
|
|
|
got suppressed since the last warning.
|
|
|
+ - Add new "perconnbwrate" and "perconnbwburst" consensus params to
|
|
|
+ do individual connection-level rate limiting of clients. The torrc
|
|
|
+ config options with the same names trump the consensus params, if
|
|
|
+ both are present. Replaces the old "bwconnrate" and "bwconnburst"
|
|
|
+ consensus params which were broken from 0.2.2.7-alpha through
|
|
|
+ 0.2.2.14-alpha. Closes bug 1947.
|
|
|
+ - When a router changes IP address or port, authorities now launch
|
|
|
+ a new reachability test for it. Implements ticket 1899.
|
|
|
+ - Make the formerly ugly "2 unknown, 7 missing key, 0 good, 0 bad,
|
|
|
+ 2 no signature, 4 required" messages about consensus signatures
|
|
|
+ easier to read, and make sure they get logged at the same severity
|
|
|
+ as the messages explaining which keys are which. Fixes bug 1290.
|
|
|
+ - Don't warn when we have a consensus that we can't verify because
|
|
|
+ of missing certificates, unless those certificates are ones
|
|
|
+ that we have been trying and failing to download. Fixes bug 1145.

|
|
+ - When building with --enable-gcc-warnings on OpenBSD, disable
|
|
|

- o Minor bugfixes:
|

|
- - Fix a regression introduced in 0.2.2.7-alpha that marked relays

|
|
|

own efforts to make a live consensus have failed. This change
|
|

means authorities that restart will fetch a valid consensus, and
