Because as Teor puts it: "[Resetting on 503] is exactly what we
don't want when relays are busy - imagine clients doing an automatic
reset every time they DoS a relay..."
Fixes bug 20593.
It's only safe to remove the failure limit (per 20536) if we are in
fact waiting a bit longer each time we try to download.
Fixes bug 20534; bugfix on 0.2.9.1-alpha.
We removed that feature in 0.2.4.2-alpha, but some comments seem to
have lingered.
I didn't add a changes/ file since this is just internal code cleanup.
Add experimental OnionServiceSingleHopMode and
OnionServiceNonAnonymousMode options. When both are set to 1, every
hidden service on a tor instance becomes a non-anonymous Single Onion
Service. Single Onions make one-hop (direct) connections to their
introduction and renzedvous points. One-hop circuits make Single Onion
servers easily locatable, but clients remain location-anonymous.
This is compatible with the existing hidden service implementation, and
works on the current tor network without any changes to older relays or
clients.
Implements proposal #260, completes ticket #17178. Patch by teor & asn.
squash! fixup! fixup! fixup! fixup! fixup! fixup! fixup! fixup! fixup! fixup! fixup! fixup! fixup! Implement Prop #260: Single Onion Services
Redesign single onion service poisoning.
When in OnionServiceSingleHopMode, each hidden service key is poisoned
(marked as non-anonymous) on creation by creating a poison file in the
hidden service directory.
Existing keys are considered non-anonymous if this file exists, and
anonymous if it does not.
Tor refuses to launch in OnionServiceSingleHopMode if any existing keys
are anonymous. Similarly, it refuses to launch in anonymous client mode
if any existing keys are non-anonymous.
Rewrite the unit tests to match and be more comprehensive.
Adds a bonus unit test for rend_service_load_all_keys().
One of the last piece that parses the votes and consensus in order to update
our state and make decision for the SR values.
We need to inform the SR subsystem when we set the current consensus because
this can be called when loaded from file or downloaded from other authorities
or computed.
The voting schedule is used for the SR timings since we are bound to the
voting system.

base16_decodes() now returns the number of decoded bytes. It's interface
changes from returning a "int" to a "ssize_t". Every callsite now checks the
returned value.

So, back long ago, XXX012 meant, "before Tor 0.1.2 is released, we
had better revisit this comment and fix it!"
But we have a huge pile of such comments accumulated for a large
number of released versions! Not cool.
So, here's what I tried to do:
* 0.2.9 and 0.2.8 are retained, since those are not yet released.
* XXX+ or XXX++ or XXX++++ or whatever means, "This one looks
quite important!"
* The others, after one-by-one examination, are downgraded to
plain old XXX. Which doesn't mean they aren't a problem -- just
that they cannot possibly be a release-blocking problem.
Remove support for "GET /tor/bytes.txt" DirPort request, and
"GETINFO dir-usage" controller request, which were only available
via a compile-time option in Tor anyway.
Feature was added in 0.2.2.1-alpha. Resolves ticket 19035.
This was one of our longest functions, at 600 lines. It makes a nice
table-driven URL-based function instead.
The code is a bit ugly, it leave the indentation as it is in hopes of
making pending directory.c changes easier to merge. Later we can
clean up the indentation.
Also, remove unused mallinfo export code from directory.c
Closes ticket 16698
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.
We'll back off from the request in connection_ap_handshake_attach_circuit,
or cancel it in connection_dir_close_consensus_fetches, and those are the
only places we need to check.
This improves client anonymity and avoids directory header tampering.
The extra load on the authorities should be offset by the fallback
directories feature.
This also simplifies the fixes to #18809.
After #17840 in 0.2.8.1-alpha, we incorrectly chose an IPv4
address for all DIRIND_ONEHOP directory connections,
even if the routerstatus didn't have an IPv4 address.
This likely affected bridge clients with IPv6 bridges.
Resolves#18921.
This changes simply renames them by removing "Testing" in front of them and
they do not require TestingTorNetwork to be enabled anymore.
