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 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
some cases. We fix this by not re-enabling reading on receipt of a
sendme cell when the cell queue is blocked. Fixes bug 1653. Bugfix
on 0.2.0.1-alpha. Detected by Mashael AlSabah. Original patch by
"yetonetime".
- Newly created streams were allowed to read cells onto circuits,
even if the circuit's cell queue was blocked and waiting to drain.
This created potential unfairness, as older streams would be
blocked, but newer streams would gladly fill the queue completely.
We add code to detect this situation and prevent any stream from
getting more than one free cell. Bugfix on 0.2.0.1-alpha. Partially
fixes bug 1298.
o Minor features:
- Update to the September 1 2010 Maxmind GeoLite Country database.
- Warn when CookieAuthFileGroupReadable is set but CookieAuthFile is
not. This would lead to a cookie that is still not group readable.
Closes bug 1843. Suggested by katmagic.
- When logging a rate-limited warning, we now mention how many messages
got suppressed since the last warning.
o Minor bugfixes:
- Fix a regression introduced in 0.2.2.7-alpha that marked relays
down if a directory fetch fails and you've configured either
bridges or EntryNodes. The intent was to mark the relay as down
_unless_ you're using bridges or EntryNodes, since if you are
then you could quickly run out of entry points.
- Authorities will now attempt to download consensuses if their
own efforts to make a live consensus have failed. This change
means authorities that restart will fetch a valid consensus, and
it means authorities that didn't agree with the current consensus
will still fetch and serve it if it has enough signatures. Bugfix
on 0.2.0.9-alpha; fixes bug 1300.
- Ensure DNS requests launched by "RESOLVE" commands from the
controller respect the __LeaveStreamsUnattached setconf options. The
same goes for requests launched via DNSPort or transparent
proxying. Bugfix on 0.2.0.1-alpha; fixes bug 1525.
- Allow handshaking OR connections to take a full KeepalivePeriod
seconds to handshake. Previously, we would close them after
IDLE_OR_CONN_TIMEOUT (180) seconds, the same timeout as if they
were open. Bugfix on 0.2.1.26; fixes bug 1840. Thanks to mingw-san
for analysis help.
- Rate-limit "Failed to hand off onionskin" warnings.
- Fix the Windows directory-listing code. A bug introduced in
0.2.2.14-alpha could make Windows directory servers forget to load
some of their cached v2 networkstatus files.
o Minor bugfixes (compile fixes):
- Squash a compile warning on OpenBSD. Reported by Tas; fixes
bug 1848.
- When building with --enable-gcc-warnings on OpenBSD, disable
warnings in system headers. This makes --enable-gcc-warnings
pass on OpenBSD 4.8.
- On Windows, build correctly either with or without Unicode support.
This is necessary so that Tor can support fringe platforms like
Windows 98 (which has no Unicode), or Windows CE (which has no
non-Unicode). Bugfix on 0.2.2.14-alpha. Fixes bug 1797.
o Testing
- Add a unit test for cross-platform directory-listing code.
Changes in version 0.2.2.15-alpha - 2010-08-18
