Changes in version 0.1.2.1-alpha - 2006-08-16 (in progress)
|
||||
o Major changes:
|
||||
- Add async dns code from Adam Langley, tweaked to build on OSX.
|
||||
Only enabled when you pass the --enable-eventdns argument to
|
||||
configure.
|
||||
- Add async dns code from Adam Langley, tweaked to build on OSX
|
||||
and Windows. Only enabled when you pass the --enable-eventdns
|
||||
argument to configure. Implement a priority queue to track
|
||||
when cached DNS resolves will expire, now that we obey the
|
||||
time-to-live (TTL) values we get back.
|
||||
- Stop fetching descriptors if you're not a dir mirror and you
|
||||
haven't tried to establish any circuits lately.
|
||||
haven't tried to establish any circuits lately. This currently
|
||||
causes some dangerous behavior, because when you start up again
|
||||
you'll use your ancient server descriptors.
|
||||
- Split circuit_t into origin_circuit_t and or_circuit_t, and
|
||||
split connection_t into edge, or, dir, control, and base structs.
|
||||
These will save quite a bit of memory on busy servers, and they'll
|
||||
also help us track down bugs and spec mismatches.
|
||||
- Instead of adding server descriptors, v1 directories, or v2
|
||||
networkstatus docs to buffers en masse, directory servers add them
|
||||
on the fly as their outbufs are depleted. This will save memory
|
||||
on busy dirservers.
|
||||
|
||||
o Minor changes:
|
||||
- New dirport behavior: if you have your dirport set, you are
|
||||
now a directory mirror, whether or not your orport is set.
|
||||
- New dirport behavior: if you have your dirport set, you download
|
||||
descriptors aggressively like a directory mirror, whether or not
|
||||
your orport is set.
|
||||
- Minor changes so Tor builds with mingw on windows.
|
||||
- Start compiling on MSVC6 now. Patch from Frediano Ziglio.
|
||||
- Claim a commonname of Tor, rather than TOR, in TLS handshakes.
|
||||
Maybe this will help us win the war of names.
|
||||
- Re-enable per-connection rate limiting. Get rid of the "OP
|
||||
bandwidth" concept. Lay groundwork for "bandwidth classes" --
|
||||
separate global buckets that apply depending on what sort of conn
|
||||
it is.
|
||||
- Add a man page entry for ProtocolWarnings.
|
||||
- Add more asserts to track down an assert error on a windows Tor
|
||||
server with connection_add being called with socket = -1.
|
||||
server with connection_add being called with socket == -1.
|
||||
- Add TestVia config option to the man page.
|
||||
|
||||
- Allow Tor to start when RunAsDaemon is set but no logs are set.
|
||||
|
||||
- Export the default exit policy via the control port, so controllers
|
||||
don't need to guess what it is / will be later.
|
||||
|
||||
- Fix configure.in to not produce broken configure files with
|
||||
more recent versions of autoconf. Thanks to Clint for his auto*
|
||||
voodoo.
|
||||
|
||||
|
||||
- mmap cached-routers file too.
|
||||
|
||||
- refuse to write an iso_time which we can't parse, when dumping
|
||||
bandwidth state. this fixes the particular incident in bug 308,
|
||||
but the general issue remains.
|
||||
|
||||
- Drop compatibility with obsolete Tors that permit create cells
|
||||
to have the wrong circ_id_type.
|
||||
|
||||
- Get rid of the router_retry_connections notion. Now routers
|
||||
no longer try to rebuild long-term connections to directory
|
||||
authorities, and directory authorities no longer try to rebuild
|
||||
long-term connections to all servers. We still don't hang up
|
||||
connections in these two cases though -- we need to look at it
|
||||
more carefully to avoid flapping, and we likely need to wait til
|
||||
0.1.1.x is obsolete.
|
||||
|
||||
- Remove even more protocol-related warnings from Tor server logs,
|
||||
such as bad TLS handshakes and malformed begin cells.
|
||||
|
||||
- Add X-Your-Address-Is directory http header so clients can get
|
||||
some hints about their current network location. It parses
|
||||
Forwarded-For and X-Forwarded-For http headers to avoid listing
|
||||
proxy addresses if possible. It's not authenticated, so use
|
||||
with care.
|
||||
- Allow servers with no hostname or IP address to learn their
|
||||
IP address by asking the directory authorities. This code only kicks
|
||||
in when you would normally have exited with a "no address" error.
|
||||
|
||||
- Handle reporting OR_CONN_EVENT_NEW events to the controller.
|
||||
|
||||
- If we are using an exit enclave and we can't connect, e.g. because
|
||||
its webserver is misconfigured to not listen on localhost, then
|
||||
back off and try connecting from somewhere else before we fail.
|
||||
|
||||
- Start publishing one minute or so after we find our ORPort
|
||||
to be reachable. This will help reduce the number of descriptors
|
||||
we have for ourselves floating around, since it's quite likely
|
||||
other things (e.g. DirPort) will change during that minute too.
|
||||
|
||||
- When we find our dirport to be reachable, mark our descriptor
|
||||
dirty so we'll tell the world. (fixes bug 306 reported by pnx)
|
||||
|
||||
- Define a schedule for how long to wait between retrying
|
||||
application connections. Rather than waiting a fixed amount of
|
||||
time between each retry, we wait only 5 seconds for the first,
|
||||
10 seconds for the second, and 15 seconds for each retry after
|
||||
that. Hopefully this will improve the expected user experience.
|
||||
|
||||
- Also, fork the v1 directory protocol into its own spec document,
|
||||
and mark dir-spec.txt as the currently correct (v2) spec.
|
||||
|
||||
- Fix misleading log messages: an entry guard that is "unlisted",
|
||||
as well as not known to be "down" (because we've never heard
|
||||
of it), is not therefore "up".
|
||||
|
||||
- Publish a new descriptor after we hup. this is important if our
|
||||
config has changed such that we'll want to start advertising our
|
||||
dirport now, etc.
|
||||
|
||||
- Remove code to special-case "-cvs" ending, since it has not
|
||||
actually mattered since 0.0.9.
|
||||
|
||||
- Revise and clean up the torrc.sample that we ship with; add
|
||||
a section for BandwidthRate and BandwidthBurst.
|
||||
|
||||
- Recommend libevent 1.1b for kqueue and win32 methods; deprecate
|
||||
libevent 1.0b harder; make libevent recommendation system saner.
|
||||
|
||||
- Experimentally re-enable kqueue on OSX when using libevent 1.1b
|
||||
or later. Log when we are doing this, so we can diagnose it when
|
||||
it fails.
|
||||
|
||||
- Patch from Tup to add support for transparent AP connections:
|
||||
this basically bundles the functionality of trans-proxy-tor
|
||||
into the Tor mainline. Now hosts with compliant pf/netfilter
|
||||
implementations can redirect TCP connections straight to Tor
|
||||
without diverting through SOCKS.
|
||||
|
||||
- Start being able to build universal binaries on OS X (thanks
|
||||
to Phobos).
