Previously the coverage on this function was mostly accidental,
coming as it did from test_entryconn.c. These new tests use mocking
to ensure that we actually hit the different failure and retry cases
of addressmap_get_virtual_address(), and make our test coverage a
bit more deterministic.
Closes ticket 25993.
Our previous algorithm had a nonzero probability of picking no
events to cancel, which is of course incorrect. The new code uses
Vitter's good old reservoir sampling "algorithm R" from 1985.
Fixes bug 26008; bugfix on 0.2.6.3-alpha.
This functionality was covered only accidentally by our voting-test
code, and as such wasn't actually tested at all. The tests that
called it made its coverage nondeterministic, depending on what time
of day you ran the tests.
Closes ticket 26014.
This is needed for libressl-2.6.4 compatibility, which we broke when
we merged a15b2c57e1 to fix bug 19981. Fixes bug 26005; bug
not in any released Tor.
This test was using the current time to pick the time period number,
and a randomly generated hs key. Therefore, it sometimes picked an
index that would wrap around the example dht, and sometimes would
not.
The fix here is just to fix the time period and the public key.
Fixes bug 25997; bugfix on 0.3.2.1-alpha.
This test, in test_client_pick_intro(), will have different coverage
depending on whether it selects a good intro point the first time or
whether it has to try a few times. Since it produces the shorter
coverage with P=1/4, repeat this test 64 times so that it only
provides reduced coverage with P=1/2^128. The performance cost is
negligible.
Closes ticket 25996. This test was introduced in 0.3.2.1-alpha.
I'd prefer not to do this for randomized tests, but as things stand
with this test, it produces nondeterministic test coverage.
Closes ticket 25995; bugfix on 0.2.2.2-alpha when this test was
introduced.
By doing so, it is renamed to voting_schedule_recalculate_timing(). This
required a lot of changes to include voting_schedule.h everywhere that this
function was used.
This effectively now makes voting_schedule.{c|h} not include dirauth/dirvote.h
for that symbol and thus no dependency on the dirauth module anymore.

Originally, it was made public outside of the dirauth module but it is no
longer needed. In doing so, we put it back in dirvote.c and reverted its name
to the original one:
dirvote_authority_cert_dup() --> authority_cert_dup()

Adds two unittests:
- First checks the path selection of basic Tor circs.
- Second checks the path selection of vanguard circs.
There is a TODO on the second unittest that we might want to test sooner than
later, but it's not trivial to do it right now.
To do these unittests we needed the following mods:
- Make some functions STATIC.
- Add some more fields to the big fake network nodes of test_entrynodes.c
- Switch fake node nicknames to base32 (because base64 does not produce valid nicknames).
This is a pretty big commit but it only moves these files to src/or/dirauth:
dircollate.c dirvote.c shared_random.c shared_random_state.c
dircollate.h dirvote.h shared_random.h shared_random_state.h
Then many files are modified to change the include line for those header files
that have moved into a new directory.
Without using --disable-module-dirauth, everything builds fine. When using the
flag to disable the module, tor doesn't build due to linking errors. This will
be addressed in the next commit(s).
No code behavior change.

Many functions become static to the C file or exposed to the tests within the
PRIVATE define of dirvote.h.
This commit moves a function to the top. No code behavior change.

Because we rescan the main loop event list if the global map of services has
changed, this makes sure it does work.
Signed-off-by: David Goulet <dgoulet@torproject.org>
Because ADD_ONION/DEL_ONION can modify the global service map (both for v2 and
v3), we need to rescan the event list so we either enable or disable the HS
service main loop event.

Implement the ability to set flags per events which influences the set up of
the event.
This commit only adds one flag which is "need network" meaning that the event
is not enabled if tor has disabled the network or if hibernation mode.

Needed to run tests from the tarball else the geoip unit test would fail by
not finding that file.

Our main function, though accurate on all platforms, can be very
slow on 32-bit hosts. This one is faster on all 32-bit hosts, and
accurate everywhere except apple, where it will typically be off by
1%. But since 32-bit apple is a relic anyway, I think we should be
fine.
This part of the code was the only part that used "cached
getttimeofday" feature, which wasn't monotonic, which we updated at
slight expense, and which I'd rather not maintain.
