The options_any_client_port_set() returns true if the ControlPort is set which
is wrong because we can have that port open but still not behave as a tor
client (like many relays for instance).

Remove v3 optimization which made Tor not detect disabling services.
This optimization is not so needed because we only call that function after HUP
anyway.
Fixes bug #25761.
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.
Stop saying in the manual that clients cache ipv4 dns answers from exit
relays. We haven't used them since 0.2.6.3-alpha, and in ticket 24050
we stopped even caching them as of 0.3.2.6-alpha, but we forgot to say
so in the man page.
Fixes bug 26052; bugfix on 0.3.2.6-alpha.
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 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.
When directory authorities read a zero-byte bandwidth file, they log
a warning with the contents of an uninitialised buffer. Log a warning
about the empty file instead.
Fixes bug 26007; bugfix on 0.2.2.1-alpha.
LibreSSL, despite not having the OpenSSL 1.1 API, does define
OPENSSL_VERSION in crypto.h. Additionally, it apparently annotates
some functions as returning NULL, so that our unit tests need to be
more careful about checking for NULL so they don't get compilation
warnings.
Closes ticket 26006.
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.
Arguably, the conditions under which these events happen should be a
bit different, but the rules are complex enough here that I've tried
to have this commit be pure refactoring.
Closes ticket 25952.
Finally, before this code goes away, take a moment to look at the
amazing way that we used to try to have an event happen
every N seconds:
get_uptime() / N != (get_uptime()+seconds_elapsed) / N
Truly, it is a thing of wonder. I'm glad we didn't start using this
pattern everywhere else.
