If a directory server runs out of space in the connection table
as it's processing a begin_dir request, it will free the exit stream
but leave it attached to the circuit, leading to unpredictable
behavior. (Reported by seeess, fixes bug 425.)


svn:r10154

from a circuit, even if the exit node is in the middle.

there are probably a few more places that need this fix too.


svn:r10076

 Misc cleanup and bulletproofing on r10056.


svn:r10058

so we can exit from the middle of the circuit.


svn:r10056

 Initial version of code to stop using socket pairs for linked connections.  Superficially, it seems to work, but it probably needs a lot more testing and attention.


svn:r9995

 Try to fix bug 410: move responsibility for attaching/detaching initial streams from circuits into dns_resolve.  Needs refactoring a little.


svn:r9931

 A surprisingly simple patch to stop reading on edge connections when their circuits get too full, and start again when they empty out.  This lets us remove the logic to block begin_dir conns when the corresponding or conns get full: it was already broken by cell queues anyway.


svn:r9905

 Possibly resolve bug reported by xiando.


svn:r9903

 Eliminate more redundant circuit_t arguments when edge_connection_t is already supplied and the circuit is already attached.


svn:r9900

 Refactor a bunch of functions that take edge_connection_t not to also take a crypt_path_t; the cpath is implicit.


svn:r9899

whether we've attached a stream.


svn:r9883

stricter rate limiting to all OR conns except those that have
been touched by local circuits.


svn:r9882

behavior for getinfo addr-mappings/*. this is because
the code and spec have been mismatched since at least
0.1.1.x, so i would be surprised if nobody at all is
relying on the current behavior.

backport candidate.

svn:r9822

 Make all LD_BUG log messsages get prefixed with "Bug: ".  Remove manually-generated "Bug: "s from log-messages.  (Apparently, we remembered to add them about 40% of the time.)


svn:r9733

 Make remap stream events have a souce; make them generated every time we get a successful connected or resolved cell.  Also change reported stream target address to IP consistently when we get the IP from an exit node.


svn:r9624

 Resolve 56 DOCDOC comments.


svn:r9594

 Fix a longstanding dnsworker-related bug: when we decide to kill a DNS worker for having been in use too long, and we independently decide to close one of the exit connections waiting for that DNS worker (perhaps because we got an END relay cell), it was possible for us to try to double-free the connection.  We were smart enough to detect this and assert, but not smart enough to fix this bug before now.  This should resolve bug 390.  Backport candidate.


svn:r9581

 Update copyright dates.


svn:r9570

we get when we hang up on an unhandshaked socks connection. i'm
still seeing these from polipo. darn it.


svn:r9565

polipo bug.


svn:r9553

svn:r9552

 Fix patch for 9510: never call control_event_stream_status on an exit connection. Should fix assert() noticed by xiando.


svn:r9514

 Report stream end events where a resolve succeeded or where we got a socks protocol error correctly, rather than calling both of them "INTERNAL".  Turn ALREADY_SOCKS_REPLIED into a flag rather than a reason.  This will help debug 367 part 2 a little.


svn:r9511

 Fix third case of bug 367: make circuit get sent along with END_STREAM_REASON_DESTROY stream CLOSED events.


svn:r9510

svn:r9495

 Add a REMAP state to stream events so that controllers can learn exactly when the target address for a stream has changed.  May help Vidalia resolve confusions related to bug 375.


svn:r9484

 Removing the last DOCDOC comment hurt so much that I had to use Doxygen to identify undocumented macros and comments, and add 150 more DOCDOCs to point out where they were.  Oops.  Hey, kids!  Fixing some of these could be your first Tor patch!


svn:r9477

 Resolve remaining DOCDOC comments.


svn:r9476

"DNS resolve socks failed" handshake reply; just close it.


svn:r9437

 This one is a little tricky.  Our BEGIN_DIR implementation has a
 problem: the dirserv conns will decide they can flush all their data
 immediately, since the edge_conns will read greedily.
 
 For our 0.1.2 workaround, we track which or_conn a bridged dirserv
 conn is attached to, and stop writing when its outbuf is too full, and
 start writing again when the or_conn's outbuf empties out a little.
 
 This requires a bit of pointer management.  Let's hope it works.
 


svn:r9432

 Fix argument types in printf: try to make buildbot happier.


svn:r9403

svn:r9400

svn:r9395

 Implement SOCKS_BAD_HOSTNAME status event. Defer remaining status events.  Clean up control-spec.txt a little, and fill in recommendations for events.


svn:r9374

handshake to finish. Previously we would let them sit around for
days, if the connecting application didn't close them either.

Also take this opportunity to refactor a duplicate bit of circuituse.c.

And change the semantics of SocksTimeout slightly, but I think it'll
be ok.


svn:r9350

 Check addresses for rfc953-saneness at exit too, and give a PROTOCOL_WARN when they fail.  Also provide a mechanism to override this, so blossom can have its @@##$$^.whatever.exit hostnames if it wants.

and add a todo item for nick in case he gets bored :)
