      first pass: obey log convention · 9e5cafc3
      Roger Dingledine authored
      ERR is if something fatal just happened
      
      WARNING is something bad happened, but we're still running. The bad thing
      is either a bug in the code, an attack or buggy protocol/implementation
      of the remote peer, etc. The operator should examine the bad thing and
      try to correct it.
      (No error or warning messages should be expected. I expect most people
      to run on -l warning eventually.)
      
      NOTICE is never ever used.
      
      INFO means something happened (maybe bad, maybe ok), but there's nothing
      you need to (or can) do about it.
      
      DEBUG is for everything louder than INFO.

      Refactor buffers; implement descriptors. · 3d4ccb78
      Nick Mathewson authored
      'buf_t' is now an opaque type defined in buffers.c .
      
      Router descriptors now include all keys; routers generate keys as
      needed on startup (in a newly defined "data directory"), and generate
      their own descriptors.  Descriptors are now self-signed.
      
      Implementation is not complete: descriptors are never published; and
      upon receiving a descriptor, the directory doesn't do anything with
      it.
      
      At least "routers.or" and orkeygen are now obsolete, BTW.

      cleanups, bugfixes, more verbose logs · 40d0fca6
      Roger Dingledine authored
      Fixed up the assert_*_ok funcs some (more work remains)
      
      Changed config so it reads either /etc/torrc or the -f arg, never both
      
      Finally tracked down a nasty bug with our use of tls:
        It turns out that if you ask SSL_read() for no more than n bytes, it
        will read the entire record from the network (and maybe part of the next
        record, I'm not sure), give you n bytes of it, and keep the remaining
        bytes internally. This is fine, except our poll-for-read looks at the
        network, and there are no bytes pending on the network, so we never know
        to ask SSL_read() for more bytes. Currently I've hacked it so if we ask
        for n bytes and it returns n bytes, then it reads again right then. This
        will interact poorly with our rate limiting; we need a cleaner solution.

      Start of port to win32. Missing are: · c336c99e
      Nick Mathewson authored
        - signal support
        - forking for DNS farm
        - changes for async IO
        - daemonizing
      
      In other words, some files still don't build, and the ones that do build,
      do nonblocking IO incorrectly.
      
      I'm also not checking in the project files till I have a good place
      for them.

      major overhaul: dns slave subsystem, topics · c35373a2
      Roger Dingledine authored
      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.

      Implemented link padding and receiver token buckets · 117cbeea
      Roger Dingledine authored
      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.
