Re: [tor-talk] Tor 0.2.3.2-alpha is out

Tor 0.2.3.2-alpha introduces two new experimental features:
microdescriptors and pluggable transports. It also continues cleaning
up a variety of recently introduced features.

Changes in version 0.2.3.2-alpha - 2011-07-18
o Major features:
- Clients can now use microdescriptors instead of regular descriptors
to build circuits. Microdescriptors are authority-generated
summaries of regular descriptors' contents, designed to change
very rarely (see proposal 158 for details). This feature is
designed to save bandwidth, especially for clients on slow internet
connections. It's off by default for now, since nearly no caches
support it, but it will be on-by-default for clients in a future
version. You can use the UseMicrodescriptors option to turn it on.
First, thank you for implementing this.
I've download, compiled, and installed version 0.2.3.2-alpha. I
previously ran version 0.2.1.30. I did not delete or alter ~/.tor
between versions. I've added the following line to torrc:
UseMicrodescriptors 1
So far, after a brief test, everything seems to be fine. I was curious
about what was logged and wondering if it represents any kind of an
error or bug. The full log is listed at the end of this email. The
lines I am wondering about are:
Jul 20 19:42:30 Host Tor[9506]: I learned some more directory
information, but not enough to build a circuit: We have only 0/2480
usable microdescriptors.
Jul 20 19:43:22 Host Tor[9506]: We now have enough directory information
to build circuits.
Jul 20 19:44:10 Host Tor[9506]: Bootstrapped 100%: Done.
I am wondering if the first line is accurately reporting the state when
52 seconds later (with a 52kbps connection) it reports it has enough
information to build circuits and 100 seconds after which, it reports
100% bootstrapped and stops downloading data (observer using iftop).
Here is the full log (the two SIGHUPs were sent from a different command):
Jul 20 19:41:41 Host Tor[9506]: Parsing GEOIP file
/usr/local/share/tor/geoip.
Jul 20 19:41:42 Host Tor[9506]: Configured to measure statistics. Look
for the *-stats files that will first be written to the data directory
in 24 hours from now.
Jul 20 19:41:42 Host Tor[9506]: OpenSSL OpenSSL 0.9.8b 04 May 2006
[90802f] looks like it's older than 0.9.8l, but some vendors have
backported 0.9.8l's renegotiation code to earlier versions, and some
have backported the code from 0.9.8m or 0.9.8n. I'll set both
SSL3_FLAGS and SSL_OP just to be safe.
Jul 20 19:41:42 Host Tor[9506]: Reloaded microdescriptor cache. Found 0
descriptors.
Jul 20 19:41:43 Host Tor[9506]: I learned some more directory
information, but not enough to build a circuit: We have no usable
consensus.

server.
Jul 20 19:41:44 Host Tor[9506]: Heartbeat: Tor's uptime is 0:00 hours,
with 1 circuits open. I've pushed 0 kB and received 0 kB.

consensus.
Jul 20 19:42:15 Host Tor[9506]: Received reload signal (hup). Reloading
config and resetting internal state.
Jul 20 19:42:15 Host Tor[9506]: Read configuration file
"/usr/local/etc/tor/torrc".
Jul 20 19:42:15 Host Tor[9506]: ControlPort is open, but no
authentication method has been configured. This means that any program
on your computer can reconfigure your Tor. That's bad! You should
upgrade your Tor controller as soon as possible.

Looks like client functionality is working.
