-Catching memory leaks in XS
+HackFest: Results
</h1>
<div class="CONTENT">
-<div style="text-align: right;"><i> I slay dragons, yonder</i></div><br />So I am trying to find and plug memory leaks in SDL perl. Most of the <a href="https://rt.cpan.org/Ticket/Display.html?id=49084">memory leaks</a> occur because in XS a reference is still held. One very expensive mem leak was caught by TELS really early on <a href="https://rt.cpan.org/Ticket/Display.html?id=17976">here</a>. The problem occurs where in XS there is<br /><br /><blockquote><i>RETVAL</i><i> = (cast *) safemalloc( ... );</i></blockquote> and safefree(...) is never called.<br />Here is a in <a href="http://github.com/kthakore/SDL_perl/blob/63ebaa682697728f5946f700a2b2c12534b1b821/src/SDL.xs">code example</a> lines 1082 on. <br /><br />My question is how I can mitigate these memory leaks? One idea I had was to store all malloc'd pointers to an array that is safefree'd on DESTROY or hooked into perl GC somehow .<br /><br /><br />Any guidance is helpful.<br /><br /><i>--yapgh</i><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3102167581424744259-7742659740534179607?l=yapgh.blogspot.com' alt='' /></div></div></div>

+<ol><li>MacOSX build is working again. It's still rough but Tetris works on it now. dngor++</li>
+<li><a href="http://search.cpan.org/%7Ekthakore/SDL-Tutorial-Tetris-0.015/">SDL::Tutorial::Tetris</a> is on CPAN as v0.15. nferraz++</li>
+<li><a href="http://github.com/m4gnet/SDL_perl/commit/9957e76f888ac71a911e3a71c2783141748d2387">SDL Perl docs</a> are a little better now. magnet++</li>
+<li>Finally experimental <a href="http://github.com/kthakore/SDL_perl/tree/experimental">Rect and Game::Rect</a> are behaving. There is still more work needed in Game::Rect. Moreover there are more tests on the experimental release. garu++</li>
+<li>Also POGL is <a href="http://sdlperl.pastebin.com/f78b8c1b9">working</a> experimentally with SDL. <br />
+</li>
+</ol>Hopefully I can get the first three results into the next release soon. The next release 2.2.3 will go up as a developmental release first. Also the experimental branch is going up as version 2_4.<br />
