[tor-talk] Tor 0.3.4.3-alpha is released

[Nick Mathewson]

Hi, all!

There's a new alpha Tor release!  Because it's an alpha, you should
only run it if you're ready to find more bugs than usual, and report
them on trac.torproject.org.

The source code is available from the usual place on
www.torproject.org; if you build Tor from source, why not give it a
try?  And if you don't build Tor from source, packages should be ready
over the coming days, with a Tor Browser alpha release likely over the
next several weeks.  (Tomorrow's planned TB alpha will probably still
have 0.3.4.2-alpha.)

Here's what's new!

Changes in version 0.3.4.3-alpha - 2018-06-26
  Tor 0.3.4.3-alpha fixes several bugs in earlier versions, including
  one that was causing stability issues on directory authorities.

  o Major bugfixes (directory authority):
    - Stop leaking memory on directory authorities when planning to
      vote. This bug was crashing authorities by exhausting their
      memory. Fixes bug 26435; bugfix on 0.3.3.6.

  o Major bugfixes (rust, testing):
    - Make sure that failing tests in Rust will actually cause the build
      to fail: previously, they were ignored. Fixes bug 26258; bugfix
      on 0.3.3.4-alpha.

  o Minor feature (directory authorities):
    - Stop warning about incomplete bw lines before the first complete
      bw line has been found, so that additional header lines can be
      ignored. Fixes bug 25960; bugfix on 0.2.2.1-alpha

  o Minor features (relay, diagnostic):
    - Add several checks to detect whether Tor relays are uploading
      their descriptors without specifying why they regenerated them.
      Diagnostic for ticket 25686.

  o Minor features (unit tests):
    - Test complete bandwidth measurements files, and test that
      incomplete bandwidth lines only give warnings when the end of the
      header has not been detected. Fixes bug 25947; bugfix
      on 0.2.2.1-alpha

  o Minor bugfixes (compilation):
    - Refrain from compiling unit testing related object files when
      --disable-unittests is set to configure script. Fixes bug 24891;
      bugfix on 0.2.5.1-alpha.
    - When linking the libtor_testing.a library, only include the
      dirauth object files once. Previously, they were getting added
      twice. Fixes bug 26402; bugfix on 0.3.4.1-alpha.
    - The --enable-fatal-warnings flag now affects Rust code as well.
      Closes ticket 26245.

  o Minor bugfixes (onion services):
    - Recompute some consensus information after detecting a clock jump,
      or after transitioning from a non-live consensus to a live
      consensus. We do this to avoid having an outdated state, and
      miscalculating the index for next-generation onion services. Fixes
      bug 24977; bugfix on 0.3.2.1-alpha.

  o Minor bugfixes (relay):
    - Relays now correctly block attempts to re-extend to the previous
      relay by Ed25519 identity. Previously they would warn in this
      case, but not actually reject the attempt. Fixes bug 26158; bugfix
      on 0.3.0.1-alpha.

  o Minor bugfixes (testing):
    - Fix compilation of the doctests in the Rust crypto crate. Fixes
      bug 26415; bugfix on 0.3.4.1-alpha.
    - Instead of trying to read the geoip configuration files from
      within the unit tests, instead create our own ersatz files with
      just enough geoip data in the format we expect. Trying to read
      from the source directory created problems on Windows with mingw,
      where the build system's paths are not the same as the platform's
      paths. Fixes bug 25787; bugfix on 0.3.4.1-alpha.
    - Refrain from trying to get an item from an empty smartlist in
      test_bridges_clear_bridge_list. Set DEBUG_SMARTLIST in unit tests
      to catch improper smartlist usage. Furthermore, enable
      DEBUG_SMARTLIST globally when build is configured with fragile
      hardening. Fixes bug 26196; bugfix on 0.3.4.1-alpha.
