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


svn:r9931

 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

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


svn:r9736

 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

 Two XXX012 comments turned out to be bogus; remove them and document why.


svn:r9625

 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

 Remove XXXX012 for apparently resolved bug


svn:r9548

 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

 Add missing return statement.


svn:r9478

 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

 Fail when we are unable to parse the nameserver configuration.


svn:r9475

 Call stat() slightly less often; use fstat() when possible.


svn:r9472

 Re-enable server side PTR-record cacheing.


svn:r9468

 Fix a bug in our assertions related to removing recently-completed DNS lookup attempts on exit.  It is okay to find a cache entry with the same name as a DONE entry, so long it is not the same struct as the DONE entry.


svn:r9467

 Fix/update some XXX012 points.


svn:r9456

 Add documentation to dns.c (mainly to test new buildbot version)


svn:r9393

svn:r9387

 Free CACHE_STATE_DONE cached_router_t items on dns_free_all().


svn:r9386

svn:r9365

 Be even more clever about severity of messages from eventdns: NOTICE when the first nameserver comes up; INFO on subsequent ones.


svn:r9364

 Answer questions from r9348.


svn:r9358

svn:r9348

 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.


svn:r9336

 Fix a crash bug in the presence of DNS hijacking.


svn:r9333

time to put out the bugfix release.


svn:r9309

 Implement DNS-related status events.


svn:r9285

 Re-enable warning when we resolve an already resolved address.  We only warn here now if the address is not a testing address.  Also, refactor out a function to check whether an address is used for testing.


svn:r9280

svn:r9270

 If we only have a single nameserver, raise the threshold to decide that the nameserver is dead.  (Another fumbling attempt to do something about bug 326.)


svn:r9203

 Partial solution to 326: downgrade single-nameserver failures to INFO.


svn:r9201

 Refactor and unify my-ip-addr-changed logic.  Make change in IP address or in nameservers reset and relaunch DNS hijacking tests.


svn:r9200

 Fix bug 364: check for whether popular hostnames (curently google, yahoo, mit, and slashdot) are getting wildcarded.  If they are, we are probably behind a DNS server that is useless: change our exit policy to reject *:*.


svn:r9199

 Resolve bug 363: do not fall back to 127.0.0.1 when no nameservers are configured.  Instead, have the admin fix resolv.conf or configure a nameserver.


svn:r9157

also fix a bug next to it that i noticed.


svn:r8784

 Change HT_INIT from a special-case to a macro-calling-a-function like the rest of ht.h.  This might prevent errors if somebody did, I dunno, "HT_INIT(tp, hashtable++)". Based on a patch from Watson Ladd.
