whatever file got committed.  They were not actually useful for

bf80e2df3f Replace calls to time(NULL) that occur on the order of once per read, one per write, or once per cell with calls to a function that looks at a cached value of time. This is tricksy to benchmark, since it will only help on systems where time() is a syscall and syscalls are relatively slow.

5822e14dc9 When a stream at an exit relay is in state "resolving" or
"connecting" and it receives an "end" relay cell, the exit relay
would silently ignore the end cell and not close the stream. If
the client never closes the circuit, then the exit relay never
closes the TCP connection. Bug introduced in Tor 0.1.2.1-alpha;
reported by "wood".

bca46cc628 backport candidate:
The "ClientDNSRejectInternalAddresses" config option wasn't being
consistently obeyed: if an exit relay refuses a stream because its
exit policy doesn't allow it, we would remember what IP address
the relay said the destination address resolves to, even if it's
an internal IP address. Bugfix on 0.2.0.7-alpha; patch by rovv.

Add a couple of (currently disabled) strategies for trying to avoid using too much ram in memory pools: prefer putting new cells in almost-full chunks, and be willing to free the last empty chunk if we have not needed it for a while.  Also add better output to mp_pool_log_status to track how many mallocs a given memory pool strategy is saving us, so we can tune the mempool parameters.

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.

Initial version of circuit-based cell queues.  Instead of hammering or_conns with piles of cells, queue cells on their corresponding circuits, and append them to the or_conn as needed.

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.

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.

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.

0dbf725927 Infrastructure to test BEGIN_DIR cells.
New socks command CONNECT_DIR. New config option TunnelDirConns that
builds a circ ending at the directory server and delivers a BEGIN_DIR
cell if it's running 0.1.2.2-alpha or later. We still need to make
one-hop circs when appropriate, while making other conns avoid them.

Have connection_about_to_close use an end_reason field in edge_connection_t to tell what reason to tell the controller for closing the stream.  Set end_reason in connection_edge_end, connection_mark_unattached_ap, and everwhere we set edge_has_sent_end.  Add a changelog entry.

Weasel correctly notes that we should not discard the return value from connection_exit_begin_con.  Right now, the return value is always discardable, so this does not actually cause a bug, but it might later. So fix it.

Fix longstanding bug in connection_exit_begin_conn():  Since connection_edge_end() exits when the connection is unattached, we were never sending RELAY_END cells back for failed RELAY_BEGIN attempts. Fix this.  This might make clients that were otherwise timing out either fail faster or retry faster, which is good news for us.

[Needs review.] Add a BEGIN_DIR relay cell type for an easier
 in-protocol way to connect to directory servers through Tor.
 Previously, clients could only connect to director servers over Tor
 from exit nodes, but couldn't get directory information anonymously
 from a non-exit cache without getting a directory server involved.
 
 This needs testing, and needs client-side code to actually exercise it.
