Changes in version 0.1.1.8-alpha - 2005-10-07
|
||||
o New features (major):
|
||||
- Clients don't download or use the directory anymore. Now they
|
||||
download and use network-statuses from the trusted dirservers,
|
||||
and fetch individual server descriptors as needed from mirrors.
|
||||
See dir-spec.txt for all the gory details.
|
||||
- Be more conservative about whether to advertise our DirPort.
|
||||
The main change is to not advertise if we're running at capacity
|
||||
and either a) we could hibernate or b) our capacity is low and
|
||||
we're using a default DirPort.
|
||||
- Use OpenSSL's AES when OpenSSL has version 0.9.7 or later.
|
||||
|
||||
o New features (minor):
|
||||
- Try to be smart about when to retry network-status and
|
||||
server-descriptor fetches. Still needs some tuning.
|
||||
- Stop parsing, storing, or using running-routers output (but
|
||||
mirrors still cache and serve it).
|
||||
- Consider a threshold of versioning dirservers (dirservers who have
|
||||
an opinion about which Tor versions are still recommended) before
|
||||
deciding whether to warn the user that he's obsolete.
|
||||
- Dirservers can now reject/invalidate by key and IP, with the
|
||||
config options "AuthDirInvalid" and "AuthDirReject". This is
|
||||
useful since currently we automatically list servers as running
|
||||
and usable even if we know they're jerks.
|
||||
- Provide dire warnings to any users who set DirServer; move it out
|
||||
of torrc.sample and into torrc.complete.
|
||||
- Add MyFamily to torrc.sample in the server section.
|
||||
- Add nicknames to the DirServer line, so we can refer to them
|
||||
without requiring all our users to memorize their IP addresses.
|
||||
- When we get an EOF or a timeout on a directory connection, note
|
||||
how many bytes of serverdesc we are dropping. This will help
|
||||
us determine whether it is smart to parse incomplete serverdesc
|
||||
responses.
|
||||
- Add a new function to "change pseudonyms" -- that is, to stop
|
||||
using any currently-dirty circuits for new streams, so we don't
|
||||
link new actions to old actions. Currently it's only called on
|
||||
HUP (or SIGNAL RELOAD).
|
||||
- On sighup, if UseHelperNodes changed to 1, use new circuits.
|
||||
- Start using RAND_bytes rather than RAND_pseudo_bytes from
|
||||
OpenSSL. Also, reseed our entropy every hour, not just at
|
||||
startup. And entropy in 512-bit chunks, not 160-bit chunks.
|
||||
|
||||
o Fixes on 0.1.1.7-alpha:
|
||||
- Nobody ever implemented EVENT_ADDRMAP for control protocol
|
||||
version 0, so don't let version 0 controllers ask for it.
|
||||
- If you requested something with too many newlines via the
|
||||
v1 controller protocol, you could crash tor.
|
||||
- Fix a number of memory leaks, including some pretty serious ones.
|
||||
- Re-enable DirPort testing again, so Tor servers will be willing
|
||||
to advertise their DirPort if it's reachable.
|
||||
- On TLS handshake, only check the other router's nickname against
|
||||
its expected nickname if is_named is set.
|
||||
|
||||
o Fixes forward-ported from 0.1.0.15:
|
||||
- Don't crash when we don't have any spare file descriptors and we
|
||||
try to spawn a dns or cpu worker.
|
||||
- Make the numbers in read-history and write-history into uint64s,
|
||||
so they don't overflow and publish negatives in the descriptor.
|
||||
|
||||
o Fixes on 0.1.0.x:
|
||||
- For the OS X package's modified privoxy config file, comment
|
||||
out the "logfile" line so we don't log everything passed
|
||||
through privoxy.
|
||||
- We were whining about using socks4 or socks5-with-local-lookup
|
||||
even when it's an IP in the "virtual" range we designed exactly
|
||||
for this case.
|
||||
- We were leaking some memory every time the client changes IPs.
|
||||
- Never call free() on tor_malloc()d memory. This will help us
|
||||
use dmalloc to detect memory leaks.
|
||||
- Check for named servers when looking them up by nickname;
|
||||
warn when we'recalling a non-named server by its nickname;
|
||||
don't warn twice about the same name.
|
||||
- Try to list MyFamily elements by key, not by nickname, and warn
|
||||
if we've not heard of the server.
|
||||
- Make windows platform detection (uname equivalent) smarter.
|
||||
- It turns out sparc64 doesn't like unaligned access either.
|
||||
