581795f41d auth dir servers were only modifying a server's is_running field
when they created a network status. so if nobody asked for a
network status, they would never discover that any servers are
is_running, so they could never build a circuit.

cf6ba3e76f let an authdir that's not a naming authdir start even
if it doesn't have an approved-routers file. if it does,
read it and parse it as usual.

817556315a Implement router purposes, and don't choose a non-general
purpose router when picking random nodes for a circuit.

Also implement SETROUTERPURPOSE and modify +POSTDESCRIPTOR.

This concludes bug 250 assuming it all works.

474c60b743 Cleanup on time-relaqted constants. New conventions:
1) Surround all constants by (parens), whether we'll be using them
     in a denominator or not.
  2) Express all time periods as products (24*60*60), not as multiplied-out
     constants (86400).
  3) Comments like "(60*60) /* one hour */" are as pointless as comments
     like "c = a + b; /* set c to the sum of a and b */".  Remove them.
  4) All time periods should be #defined constants, not given inline.
  5) All time periods should have doxygen comments.
  6) All time periods, unless specified, are in seconds.  It's not necessary
     to say so.

To summarize, the old (lack of) style would allow:

  #define FOO_RETRY_INTERVAL 60*60 /* one hour (seconds) */
  next_try = now + 3600;

The new style is:

  /** How often do we reattempt foo? */
  #define FOO_RETRY_INTERVAL (60*60)

  next_try = now + RETRY_INTERVAL;

390bbb0a0c Try to make tor work better through squid: Limit number of descriptors we fetch
to 96 (was 128 previously).

idea.

92ef9e37e7 Add a new config option ExitPolicyRejectPrivate which defaults to 1.
This means all exit policies will begin with rejecting private addresses,
unless the server operator explicitly turns it off.

Also, make our code to remove redundancies in the exit policy smarter,
so it can detect "reject foo, reject bar, reject *" patterns.

Lastly, we can get rid of the "exit policy implicitly accepts" code,
since we make everything more explicit now.

0e51d5d274 When the controller was submitting a descriptor, we were checking to make
sure some network-status we had referred to it, and refusing it if not.
This is bad for people who want to insert descriptors that aren't part of
the current Tor network. Now we accept them, and also give a more useful
warn message if we ask a dir mirror for a given descriptor and it gives us
one we weren't expecting.

    options even when we're using the proxy: some proxies can only proxy

e3adcbdb95 Big commit: clients start downloading and using network-statuses.
Only caches need to get running-routers; nobody needs to parse, store,
or use it.  Same for the router-status line in the directories.  Add
many #if 0's that can get removed once I'm convinced they don't
contain anything I'm forgetting.

Start all newly-parsed routers as non-running and non-valid; update
them from the list of network statuses.

Update all routers when a new networkstatus comes in.

After 3 tries for a networkstatus, clients give up until they're told
to try again.

  they were up or down.  Also enables more simplifications.
- Keep the signed descriptor inside routerinfo_t.  This makes

- Rename AddressMap (the verb) to MapAddress. Keep AddressMap as a noun.
- Check addresses for plausibility before mapping them.

ef6c9d18e7 New circuit building strategy: keep a list of ports that we've used in the past 6 hours, and always try to have 2 circuits open or on the way
that will handle each such port. (We can extend this to include addresses
if exit policies shift to require that.) Seed us with port 80 so web
browsers won't complain that Tor is "slow to start up".

This was necessary because our old circuit building strategy just involved
counting circuits, and as time went by we would build up a big pile of
circuits that had peculiar exit policies (e.g. only exit to 9001-9100)
which would take up space in the circuit pile but never get used.

Fix router_compare_addr_to_addr_policy: it was not treating a port of *
as always matching, so we were picking reject *:* nodes as exit nodes too.

If you haven't used a clean circuit in an hour, throw it away, just to
be on the safe side.

This means after 6 hours a totally unused Tor client will have no
circuits open.

- make clients cache directories and use them to seed their router lists
   at startup.  This means clients have a datadir again.
 - Introduce a global_write_bucket.  We need to respond better to exhausting
   it.
 - Remove the last vestiges of LinkPadding and TrafficShaping.
 - Configuration infrastructure support for warning on obsolete options.
 - Refactor directory header parsing to use smartlist_split_string.
 - Respond to content-encoding headers by trying to uncompress as appropriate.
 - Reply with a deflated directory when a client asks for "dir.z".
   (We could use allow-encodings instead, but allow-encodings isn't
   specified in HTTP 1.0.)
