This is the eighth development snapshot for the 0.1.2.x series. You'll
notice that it's a beta -- more mature than an alpha but not yet a
release candidate. It fixes a few crash bugs, and generally continues
to clean things up. We're getting close!
The bundles also come with Vidalia 0.0.11.
Changes in version 0.1.2.8-beta - 2007-02-26
o Major bugfixes (crashes):
- Stop crashing when the controller asks us to resetconf more than
one config option at once. (Vidalia 0.0.11 does this.)
- Fix a crash that happened on Win98 when we're given command-line
arguments: don't try to load NT service functions from advapi32.dll
except when we need them. (Bug introduced in 0.1.2.7-alpha;
resolves bug 389.)
- Fix a longstanding obscure crash bug that could occur when
we run out of DNS worker processes. (Resolves bug 390.)
o Major bugfixes (hidden services):
- Correctly detect whether hidden service descriptor downloads are
in-progress. (Suggested by Karsten Loesing; fixes bug 399.)
o Major bugfixes (accounting):
- When we start during an accounting interval before it's time to wake
up, remember to wake up at the correct time. (May fix bug 342.)
o Minor bugfixes (controller):
- Give the controller END_STREAM_REASON_DESTROY events _before_ we
clear the corresponding on_circuit variable, and remember later
that we don't need to send a redundant CLOSED event. (Resolves part
3 of bug 367.)
- Report events where a resolve succeeded or where we got a socks
protocol error correctly, rather than calling both of them
- Change reported stream target addresses to IP consistently when
we finally get the IP from an exit node.
- Send log messages to the controller even if they happen to be very
o Minor bugfixes (other):
- Display correct results when reporting which versions are
recommended, and how recommended they are. (Resolves bug 383.)
- Improve our estimates for directory bandwidth to be less random:
guess that an unrecognized directory will have the average bandwidth
from all known directories, not that it will have the average
bandwidth from those directories earlier than it on the list.
- If we start a server with ClientOnly 1, then set ClientOnly to 0
and hup, stop triggering an assert based on an empty onion_key.
- On platforms with no working mmap() equivalent, don't warn the
user when cached-routers doesn't exist.
- Warn the user when mmap() [or its equivalent] fails for some reason
other than file-not-found.
- Don't warn the user when cached-routers.new doesn't exist: that's
perfectly fine when starting up for the first time.
- When EntryNodes are configured, rebuild the guard list to contain,
in order: the EntryNodes that were guards before; the rest of the
EntryNodes; the nodes that were guards before.
- Mask out all signals in sub-threads; only the libevent signal
handler should be processing them. This should prevent some crashes
on some machines using pthreads. (Patch from coderman.)
- Fix switched arguments on memset in the implementation of
tor_munmap() for systems with no mmap() call.
- When Tor receives a router descriptor that it asked for, but
no longer wants (because it has received fresh networkstatuses
in the meantime), do not warn the user. Cache the descriptor if
we're a cache; drop it if we aren't.
- Make earlier entry guards _really_ get retried when the network
comes back online.
- On a malformed DNS reply, always give an error to the corresponding
- Build with recent libevents on platforms that do not define the
nonstandard types "u_int8_t" and friends.
o Minor features (controller):
- Warn the user when an application uses the obsolete binary v0
control protocol. We're planning to remove support for it during
the next development series, so it's good to give people some
- Add STREAM_BW events to report per-entry-stream bandwidth
use. (Patch from Robert Hogan.)
- Rate-limit SIGNEWNYM signals in response to controllers that
impolitely generate them for every single stream. (Patch from
mwenge; closes bug 394.)
- Make REMAP stream events have a SOURCE (cache or exit), and
make them generated in every case where we get a successful
connected or resolved cell.
o Minor bugfixes (performance):
- Call router_have_min_dir_info half as often. (This is showing up in
some profiles, but not others.)
- When using GCC, make log_debug never get called at all, and its
arguments never get evaluated, when no debug logs are configured.
(This is showing up in some profiles, but not others.)
o Minor features:
- Remove some never-implemented options. Mark PathlenCoinWeight as
- Implement proposal 106: Stop requiring clients to have well-formed
certificates; stop checking nicknames in certificates. (Clients
have certificates so that they can look like Tor servers, but in
the future we might want to allow them to look like regular TLS
clients instead. Nicknames in certificates serve no purpose other
than making our protocol easier to recognize on the wire.)
- Revise messages on handshake failure again to be even more clear about
which are incoming connections and which are outgoing.
- Discard any v1 directory info that's over 1 month old (for
directories) or over 1 week old (for running-routers lists).
- Do not warn when individual nodes in the configuration's EntryNodes,
ExitNodes, etc are down: warn only when all possible nodes
are down. (Fixes bug 348.)
- Always remove expired routers and networkstatus docs before checking
whether we have enough information to build circuits. (Fixes
- Put a lower-bound on MaxAdvertisedBandwidth.
