  24       <div class="date">29th April 2014</div>
  25       <div class="body"><p>I've been following <a href="http://www.getgnash.org/">the Gnash
  26 project</a> for quite a while now.  It is a free software
  27 implementation of Adobe Flash, both a standalone player and a browser
  28 plugin.  Gnash implement support for the AVM1 format (and not the
  29 newer AVM2 format - see
  30 <a href="http://lightspark.github.io/">Lightspark</a> for that one),
  31 allowing several flash based sites to work.  Thanks to the friendly
  32 developers at Youtube, it also work with Youtube videos, because the
  33 Javascript code at Youtube detect Gnash and serve a AVM1 player to
  34 those users. :) Would be great if someone found time to implement AVM2
  35 support, but it has not happened yet.  If you install both Lightspark
  36 and Gnash, Lightspark will invoke Gnash if it find a AVM1 flash file,
  37 so you can get both handled as free software.  Unfortunately,
  38 Lightspark so far only implement a small subset of AVM2, and many
  39 sites do not work yet.</p>
  40
  41 <p>A few months ago, I started looking at
  42 <a href="http://scan.coverity.com/">Coverity</a>, the static source
  43 checker used to find heaps and heaps of bugs in free software (thanks
  44 to the donation of a scanning service to free software projects by the
  45 company developing this non-free code checker), and Gnash was one of
  46 the projects I decided to check out.  Coverity is able to find lock
  47 errors, memory errors, dead code and more.  A few days ago they even
  48 extended it to also be able to find the heartbleed bug in OpenSSL.
  49 There are heaps of checks being done on the instrumented code, and the
  50 amount of bogus warnings is quite low compared to the other static
  51 code checkers I have tested over the years.</p>
  52
  53 <p>Since a few weeks ago, I've been working with the other Gnash
  54 developers squashing bugs discovered by Coverity.  I was quite happy
  55 today when I checked the current status and saw that of the 777 issues
  56 detected so far, 374 are marked as fixed.  This make me confident that
  57 the next Gnash release will be more stable and more dependable than
  58 the previous one.  Most of the reported issues were and are in the
  59 test suite, but it also found a few in the rest of the code.</p>
