Changes in version 0.4.1.2-alpha - 2019-06-05
Tor 0.4.1.2-alpha resolves numerous bugs--some of them from the previous
alpha, and some much older. It also contains minor testing improvements,

o Major bugfixes (bridges):
- Consider our directory information to have changed when our list of
bridges changes. Previously, Tor would not re-compute the status of its
directory information when bridges changed, and therefore would not
realize that it was no longer able to build circuits. Fixes part of bug
29875.
- Do not count previously configured working bridges towards our total of
working bridges. Previously, when Tor's list of bridges changed, it
would think that the old bridges were still usable, and delay fetching
router descriptors for the new ones. Fixes part of bug 29875; bugfix
on 0.3.0.1-alpha.

o Major bugfixes (Flow Control, SENDME):
- The decrement of the stream-level package window was done in a log_debug()
statement meaning that if the debug logs were not enabled, the decrement
would never happen and thus the window would be out of sync with the other
end point. Fixes bug 30628; bugfix on 0.4.1.1-alpha.

bugfix on 0.4.1.1-alpha.
 
o Major bugfixes (Onion service reachability):
- Properly clean up the introduction point map and associated state when
circuits change purpose from onion service circuits to pathbias,
measurement, or other circuit types. This should fix some instances of
introduction point failure. Fixes bug 29034; bugfix on 0.3.2.1-alpha.

o Minor features (authenticated SENDME):
- Ensure that there is enough randomness on every circuit
to prevent an attacker from successfully predicting what SENDME cells
they will need to send: at a random interval, if we have not send
randomness already, leave some extra space at the end of a cell that
we can fill with random bytes. Closes ticket 26846.

o Minor features (continuous integration):
- When running coverage builds on Travis, we now set TOR_TEST_RNG_SEED,
to avoid RNG-based coverage differences.

o Minor features (testing):
- The circuitpadding tests now use a reproducible RNG implementation,
so that if a test fails, we can learn why. Part of ticket 28878.
- Tor's tests now support an environment variable, TOR_TEST_RNG_SEED,
to set the RNG seed for tests that use a reproducible RNG.

our coverage deterministic, so that we can accurately track changes in
code coverage. Closes ticket 30519.

o Minor bugfixes (out-of-memory handler):
- When purging the DNS cache because of an out-of-memory condition,
try purging just the older entries at first. Previously, we would
try purging just the older entries at first. Previously, we would
purge the whole thing. Fixes bug 29617; bugfix on 0.3.5.1-alpha.
 
o Minor bugfixes (portability):
- Avoid crashing in our tor_vasprintf() implementation on systems that
define neither vasprintf() nor _vscprintf(). (This bug has been here
long enough that we question whether people are running Tor on such
systems, but we're applying the fix out of caution.) Fixes bug 30561;
bugfix on 0.2.8.2-alpha. Found and fixed by Tobias Stoeckmann.

o Minor bugfixes (shutdown, libevent, memory safety):
- Avoid use-after-free bugs when shutting down, by making sure that we
shut down libevent only after shutting down all of its users. We
believe these are harmless in practice, since they only occur on the
shutdown path, and do not involve any attacker-controlled data. Fixes
bug 30629; bugfix on 0.4.1.1-alpha.

o Minor bugfixes (static analysis):
- Fix several spurious Coverity warnings about the unit tests, to lower our
chances of missing any real warnings in the future. Fixes bug 30150;
