Comment (by nickm):
=== Broken thing 1:
In learned_bridge_descriptor(), when I reproduce the bug, the body of this
if-statement is never executed:
{{{
if (first) {
routerlist_retry_directory_downloads(now);
}
}}}
Interesting! Apparently, by the time we hit learned_bridge_descriptor(),
any_bridge_descriptors_known() is always true. At least, for me.
The function routerlist_retry_directory_downloads() seems pretty heavy-
weight for the general case we're concerned about here too. In my
testing, update_networkstatus_downloads() was sufficient. Writing a
patch...

Comment(by phw):
Replying to [comment:6 karsten]:
Looks like this problem also happens on normal bridges. See #9557 which
I just closed as dup, because this is very likely the same problem.
FWIW, I seem to have the opposite problem. My tor (with obfsproxy)
bootstraps fine '''only''' the first time. Subsequent bootstraps then lead
to the 60-second-problem.
Also, I can't reproduce #9557. I just tested this with tor v0.2.4.16-rc
(git-dcf6b6d7dda9ffbd) using:
{{{
tor --datadirectory /tmp/tmptor --bridge x.x.x.x:443 --controlport auto
--socksport auto
}}}
This setup worked fine for me.

Can you remind me if it also happens when you have cached descriptors? Any other info? Sorry for taking so long to respond. Yes, it seems to always happen. I just tested it again with the newest [https://www.torproject.org/dist/torbrowser/linux/tor-pluggable- transports-browser-gnu-linux-i686-2.4.16-beta-1-pt1-dev-en-US.tar.gz PTTBB]. When starting it for the very first time (i.e., with an empty data directory), it bootstraps as expected. Subsequent times stall for 60 seconds. My system is a 64-bit Debian wheezy. The PTTBB is unconfigured except that I disabled flash proxies but I remember dcf mentioning that he experienced this with flash proxies as well. And yes, this also happens with cached descriptors, i.e., the file `cached-descriptors.new` being non-empty. -- Ticket URL: https://trac.torproject.org/projects/tor/ticket/9229#comment:10 Tor Bug Tracker Wiki https://trac.torproject.org/ The Tor Project: anonymity online ___ tor-bugs mailing list tor-bugs@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-bugs

Comment(by karsten):
Huh, I wonder why nobody can reproduce the problem I'm seeing. Describing
it in more detail. Here's my torrc (note the `UseBridges 1` part which
phw doesn't seem to use, and maybe rightly so):
{{{
DataDirectory /home/ubuntu/src/client
SocksPort 9000
UseBridges 1
Bridge [scrubbed]:443
Log debug file /home/ubuntu/src/client/debug.log
Log info file /home/ubuntu/src/client/info.log
Log notice file /home/ubuntu/src/client/notice.log
LogTimeGranularity 1 msec
SafeLogging 0
}}}
[scrubbed] is a bridge I just got from bridges.tpo. I start tor (master,
7121e7b) using:
{{{
/home/ubuntu/src/tor-master/src/or/tor -f /home/ubuntu/src/client/torrc
}}}
Bootstraps to 100% just fine. Then I `rm cached-*` (but not `state`) and
re-run:
{{{
/home/ubuntu/src/tor-master/src/or/tor -f /home/ubuntu/src/client/torrc
}}}
Takes a minute to download the microdesc consensus.
phw, can you try again using a setup closer to mine?
