+Changes in version 0.2.1.23 - 2010-02-12
|
|
|
+ o Major bugfixes (performance):
|
|
|
+ - We were selecting our guards uniformly at random, and then weighting
|
|
|
+ which of our guards we'd use uniformly at random. This imbalance
|
|
|
+ meant that Tor clients were severely limited on throughput (and
|
|
|
+ probably latency too) by the first hop in their circuit. Now we
|
|
|
+ select guards weighted by currently advertised bandwidth. We also
|
|
|
+ automatically discard guards picked using the old algorithm. Fixes
|
|
|
+ bug 1217; bugfix on 0.2.1.3-alpha. Found by Mike Perry.
|
|
|
+
|
|
|
+ o Major bugfixes:
|
|
|
+ - Make Tor work again on the latest OS X: when deciding whether to
|
|
|
+ use strange flags to turn TLS renegotiation on, detect the OpenSSL
|
|
|
+ version at run-time, not compile time. We need to do this because
|
|
|
+ Apple doesn't update its dev-tools headers when it updates its
|
|
|
+ libraries in a security patch.
|
|
|
+ - Fix a potential buffer overflow in lookup_last_hid_serv_request()
|
|
|
+ that could happen on 32-bit platforms with 64-bit time_t. Also fix
|
|
|
+ a memory leak when requesting a hidden service descriptor we've
|
|
|
+ requested before. Fixes bug 1242, bugfix on 0.2.0.18-alpha. Found
|
|
|
+ by aakova.
|
|
|
+
|
|
|
+ o Minor bugfixes:
|
|
|
+ - Refactor resolve_my_address() to not use gethostbyname() anymore.
|
|
|
+ Fixes bug 1244; bugfix on 0.0.2pre25. Reported by Mike Mestnik.
|
|
|
+
|
|
|
+ o Minor features:
|
|
|
+ - Avoid a mad rush at the beginning of each month when each client
|
|
|
+ rotates half of its guards. Instead we spread the rotation out
|
|
|
+ throughout the month, but we still avoid leaving a precise timestamp
|
|
|
+ in the state file about when we first picked the guard. Improves
|
|
|
+ over the behavior introduced in 0.1.2.17.
