Tor 0.1.0.17: новая стабильная версия

Tor 0.1.0.17 fixes a crash bug for servers that enable hibernation,
lets Windows servers scale better, and tries to reduce the bandwidth
overhead from the old-style directory protocol. Both clients and servers
are encouraged to upgrade.

Changes in version 0.1.0.17 – 2006-02-17

o Crash bugfixes on 0.1.0.x:

When servers with a non-zero DirPort came out of hibernation,
sometimes they would trigger an assert.

o Other important bugfixes:

On platforms that don't have getrlimit (like Windows), we were
artificially constraining ourselves to a max of 1024
connections. Now just assume that we can handle as many as 15000
connections. Hopefully this won't cause other problems.

o Backported features:

When we're a server, a client asks for an old-style directory,
and our write bucket is empty, don't give it to him. This way
small servers can continue to serve the directory *sometimes*,
without getting overloaded.
Whenever you get a 503 in response to a directory fetch, try
once more. This will become important once servers start sending
503's whenever they feel busy.
Fetch a new directory every 120 minutes, not every 40 minutes.
Now that we have hundreds of thousands of users running the old
directory algorithm, it's starting to hurt a lot.
Bump up the period for forcing a hidden service descriptor upload
from 20 minutes to 1 hour.

Обновилась нестабильная версия (CVS) до 0.1.1.14 alpha.

Changes in version 0.1.1.14-alpha – 2006-02-20

o Bugfixes on 0.1.1.x:

Don't die if we ask for a stdout or stderr log (even implicitly)
and we're set to RunAsDaemon — just warn.
We still had a few bugs in the OR connection rotation code that
caused directory servers to slowly aggregate connections to other
fast Tor servers. This time for sure!
Make log entries on Win32 include the name of the function again.
We were treating a pair of exit policies if they were equal even
if one said accept and the other said reject — causing us to
not always publish a new descriptor since we thought nothing
had changed.
Retry pending server downloads as well as pending networkstatus
downloads when we unexpectedly get a socks request.
We were ignoring the IS_FAST flag in the directory status,
meaning we were willing to pick trivial-bandwidth nodes for "fast"
connections.
If the controller's SAVECONF command fails (e.g. due to file
permissions), let it know that it failed.

o Features:

If we're trying to be a Tor server and running Windows 95/98/ME
as a server, explain that we'll likely crash.
When we're a server, a client asks for an old-style directory,
and our write bucket is empty, don't give it to him. This way
small servers can continue to serve the directory *sometimes*,
without getting overloaded.
Compress exit policies even more — look for duplicate lines
and remove them.
Clients now honor the "guard" flag in the router status when
picking entry guards, rather than looking at is_fast or is_stable.
Retain unrecognized lines in $DATADIR/state file, so that we can
be forward-compatible.
Generate 18.0.0.0/8 address policy format in descs when we can;
warn when the mask is not reducible to a bit-prefix.
Let the user set ControlListenAddress in the torrc. This can be
dangerous, but there are some cases (like a secured LAN) where it
makes sense.
Split ReachableAddresses into ReachableDirAddresses and
ReachableORAddresses, so we can restrict Dir conns to port 80
and OR conns to port 443.
Now we can target arch and OS in rpm builds (contributed by
Phobos). Also make the resulting dist-rpm filename match the
target arch.
New config options to help controllers: FetchServerDescriptors
and FetchHidServDescriptors for whether to fetch server
info and hidserv info or let the controller do it, and
PublishServerDescriptor and PublishHidServDescriptors.
Also let the controller set the __AllDirActionsPrivate config
option if you want all directory fetches/publishes to happen via
Tor (it assumes your controller bootstraps your circuits).
