whether we have a connection open to the server right now.


svn:r10333

 Well, that was easier than I thought it would be.  Tor is now a DNS proxy as well as a socks proxy.  Probably some bugs remain, but since it A) has managed to resolve one address for me successfully, and B) will not affect anybody who leaves DNSPort unset, it feel like a good time to commit.


svn:r10317

 Make connection_array into a smartlist.


svn:r10292

 Fix GCC warnings related to local parameters/variables getting shadowed.


svn:r10198

 When logging memory usage, break down memory used in buffers by buffer type.


svn:r10004

 Rename a couple of confusing fields


svn:r9996

 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

 Track the number of connection_t separately from the number of open sockets.  It is already possible to have connections that do not count: resolving conns, for one.  Once we move from socketpairs to linked conns, and once we do dns proxying, there will be lots of such connections.


svn:r9994

 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

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


svn:r9899

because we have no way of remembering what their purpose was when
we restart.


svn:r9894

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


svn:r9882

now that's just defined as answers to directory requests.


svn:r9881

 Remove dnsworkers and related code. there goes another 550 lines of code.


svn:r9736

 Remove support for v0 control protocol from 0.2.0.x trunk; send back error when we receive a v0 control message.  (Leave "if(v1){...}"blocks indented for now so this patch is easier to read.)  ((Finally, the linecount goes _down_ a little.))


svn:r9735

 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

 Fix connection_get_by_type_state_rendquery(): This has been bogus for most of 0.1.2.x.  Thanks to Karsten Loesing for finding the bug; fixes bug 399.


svn:r9651

 Tweak stream_bw patch: Remove a couple of redundant checks, save 8 bytes per edge connection, fix spelling in the changelog; expand spec.


svn:r9586

 Apply stream_bw patch from Robert Hogan.


svn:r9585

 Update copyright dates.

svn:r9552

 Resolve some XXXX012 items:
   - Remove PathlenCoinWeight: if we want it again, we can add it
     back in.
   - Ditto with RelayBandwidth*.
   - Decide to leave in the "hey, you didn't set end_reason!" BUG log message,
     but stop telling people to bug me personally.
   - Postpone strengthening assert_connection_ok(): it's important, but 
     it's also a good way to introduce weird bugs.
   - Move some expensive consistency checking from dns_free_all() into
     assert_cache_ok().


svn:r9533

 Update assert_connection_ok() to match the "block tunnelled dir conn if the or conn is full" logic.  This may fix bug 385.


svn:r9479

 Audit non-const char arguments; make a lot more of them const.


svn:r9466

 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.

connection_is_rate_limited(). One day this will be useful.


svn:r9422

svn:r9421

 Remove redundant check for whether _connection_write_to_buf_impl is called with a zlib and a non-directory connection: TO_DIR_CONN will already assert if it gets a non-dir connection.


svn:r9390

trying to flush.

Also add a new XXX012.

aggressively. my vidalia bandwidth graph, when rate limiting
to 32kB/s, has the "write" line constantly at 32kB. I can't
imagine what's going on with the relay latency but it can't
be good.


svn:r9366

 set or_conn->tls_error to 0 on non-error to avoid looking at stale errors.


svn:r9359

 Tidy up ORCONN reason patch from Mike Perry.  Changes: make some of the handling of TLS error codes less error prone.  Enforce house style wrt spaces.  Make it compile with --enable-gcc-warnings.  Only set or_conn->tls_error in the case of an actual error.  Add a changelog entry.


svn:r9355

 Patch from Mike Perry: Track reasons for OR connection failure; display them in control events. Needs review and revision.


svn:r9354

 Fix an XXXX012 in connection.c: prevent overflows on unfeasibly-high-bandwidth servers on 32-bit architectures.
