| * | make reusing circuits work (and be the default)•••performance is better, but not by much. not sure why yet.
svn:r153
| Roger Dingledine | 2003-02-06 |
| * | major overhaul: dns slave subsystem, topics•••on startup, it forks off a master dns handler, which forks off dns
slaves (like the apache model). slaves as spawned as load increases,
and then reused. excess slaves are not ever killed, currently.
implemented topics. each topic has a receive window in each direction
at each edge of the circuit, and sends sendme's at the data level, as
per before. each circuit also has receive windows in each direction at
each hop; an edge sends a circuit-level sendme as soon as enough data
cells have arrived (regardless of whether the data cells were flushed
to the exit conns). removed the 'connected' cell type, since it's now
a topic command within data cells.
at the edge of the circuit, there can be multiple connections associated
with a single circuit. you find them via the linked list conn->next_topic.
currently each new ap connection starts its own circuit, so we ought
to see comparable performance to what we had before. but that's only
because i haven't written the code to reattach to old circuits. please
try to break it as-is, and then i'll make it reuse the same circuit and
we'll try to break that.

tor nodes who aren't dirservers now fetch directories and autoconnect

and replace their router list with it if it parses correctly.

| Roger Dingledine | 2002-09-26 |
| * | laying the groundwork for dynamic router lists•••revamped the router reading section
reference counting for crypto pk env's (so we can dup them)
we now read and write pem pk keys from string rather than from FILE*,
in anticipation of fetching directories over a socket
(so now on startup we slurp in the whole file, then parse it as a string)
fixed a bug in the proxy side, where you could get some circuits
wedged if they showed up while the connection was being made

| * | Folded cell.? into src/or•••svn:r64
| Roger Dingledine | 2002-07-19 |
| * | Implemented congestion control•••Servers are allowed to send 100 cells initially, and can't send more until
they receive a 'sendme' cell from that direction, indicating that they
can send 10 more cells. As it currently stands, the exit node quickly
runs out of window, and sends bursts of 10 whenever a sendme cell gets
to him. This is much much much faster (and more flexible) than the old
"give each circuit 1 kB/s and hope nothing overflows" approach.
Also divided out the connection_watch_events into stop_reading,
start_writing, etc. That way we can control them separately.

| * | new link padding scheme•••we're now much more robust when bandwidth varies: instead of forcing a
fixed bandwidth on the link, we instead use what the link will give us,
up to our bandwidth.
svn:r53
| Roger Dingledine | 2002-07-16 |
| * | new config files, some bugfixes•••svn:r51
| Roger Dingledine | 2002-07-16 |
| * | Implemented link padding and receiver token buckets•••Each socket reads at most 'bandwidth' bytes per second sustained, but
can handle bursts of up to 10*bandwidth bytes.
Cells are now sent out at evenly-spaced intervals, with padding sent
out otherwise. Set Linkpadding=0 in the rc file to send cells as soon
as they're available (and to never send padding cells).
Added license/copyrights statements at the top of most files.
router->min and router->max have been merged into a single 'bandwidth'
value. We should make the routerinfo_t reflect this (want to do that,
Mat?)
As the bandwidth increases, and we want to stop sleeping more and more
frequently to send a single cell, cpu usage goes up. At 128kB/s we're
pretty much calling poll with a timeout of 1ms or even 0ms. The current
code takes a timeout of 0-9ms and makes it 10ms. prepare_for_poll()
handles everything that should have happened in the past, so as long as
our buffers don't get too full in that 10ms, we're ok.
Speaking of too full, if you run three servers at 100kB/s with -l debug,
it spends too much time printing debugging messages to be able to keep
up with the cells. The outbuf ultimately fills up and it kills that
connection. If you run with -l err, it works fine up through 500kB/s and
probably beyond. Down the road we'll want to teach it to recognize when
an outbuf is getting full, and back off.

| Roger Dingledine | 2002-07-16 |
| * | put in the support for 'router twins'•••basically, a twin is a router which is different except it shares
the same keypair. so in cases where we want to find a "next router"
and all we really care is that it can decrypt the next onion layer,
then a twin is just as good.
we still need to decide how to mark twins in the routerinfo_t and in
the routers config file.
