This commit was made mechanically by this perl script:
\#!/usr/bin/perl -w -i -p
next if /^#define FREE_AND_NULL/;
s/\bFREE_AND_NULL\((\w+),/FREE_AND_NULL\(${1}_t, ${1}_free_,/;
s/\bFREE_AND_NULL_UNMATCHED\(/FREE_AND_NULL\(/;
Right now there's a single warn_if_unnamed flag for
router_get_consensus_status_by_nickname() and
node_get_by_nickname(), that is nearly always 1. I've turned it
into an 'unsigned' bitfield, and inverted its sense. I've added the
flags argument to node_get_by_hex_id() too, though it does nothing
there right now.
I've removed the router_get_consensus_status_by_nickname() function,
since it was only used in once place.
This patch changes the warning behavior of GETINFO ns/name/<name>,
since all other name lookups from the controller currently warn.
Later I'm going to add more flags, for ed25519 support.
We also had to alter the SRV functions to take a consensus as optional
input, since we might be setting our HSDir index using a consensus that
is currently being processed and won't be returned by the
networkstatus_get_live_consensus() function.
This change has two results:
a) It makes sure we are using a fresh consensus with the right SRV value
when we are calculating the HSDir hash ring.
b) It ensures that we will not use the sr_get_current/previous()
functions when we don't have a consensus which would have falsely
triggered the disaster SRV logic.
These still won't do anything till I get the values to be filled in.
Also, I changed the API a little (with corresponding changes in
directory.c) to match things that it's easier to store.
These are taken from the proposal, and defined there. Some of them
should turn into consensus parameters.
Also, remove some dead code that was there to make compilation work,
and use ATTR_UNUSED like a normal person.
we should avoid launching a consensus fetch if we don't want one,
but if we do end up with an extra one, we should let the other checks
take care of it.
Once tor is downloading a usable consensus, any other connection
attempts are not needed.
Choose a connection to keep, favouring:
* fallback directories over authorities,
* connections initiated earlier over later connections
Close all other connections downloading a consensus.
Prop210: Add attempt-based connection schedules
Existing tor schedules increment the schedule position on failure,
then retry the connection after the scheduled time.
To make multiple simultaneous connections, we need to increment the
schedule position when making each attempt, then retry a (potentially
simultaneous) connection after the scheduled time.
(Also change find_dl_schedule_and_len to find_dl_schedule, as it no
longer takes or returns len.)
Prop210: Add multiple simultaneous consensus downloads for clients
Make connections on TestingClientBootstrapConsensus*DownloadSchedule,
incrementing the schedule each time the client attempts to connect.
Check if the number of downloads is less than
TestingClientBootstrapConsensusMaxInProgressTries before trying any
more connections.
The remaining vestige is that we continue to publish the V2dir flag,
and that, for the controller, we continue to emit v2 directory
formats when requested.
