Owing to my ignorance, it may seem odd. </div><div class="">Here it is: How long has it been since you re-compiled the socket plugin sources? I figure it’s been more than six months.</div><div class=""><br class=""></div><div class="">The confusion I have is that <a href="http://netstyle.ch" class="">netstyle.ch</a> asked you to make a change to the Cog sources, which you did. [1] </div><div class="">Now, to me, this suggests to me that every subsequent Linux Cog vm in mirandaband would have the systemd capability they asked for. </div><div class="">But that’s not my experience. </div><div class="">See, the SVN sources have what I want, but I have the impression that your binaries do not. </div><div class="">The reason I can infer anything about your compilation process is that I added the <a href="http://netstyle.ch" class="">netstyle.ch</a> diff file [2] and compiled my own interpreter vm. And it works on my Ubuntu laptop. Just like the <a href="http://netstyle.ch" class="">netstyle.ch</a> video. </div><div class="">So i thought to myself: “How could it be that there’s a difference between the Cog sources and the vm binaries at mirandabanda?”</div><div class=""> </div><div class="">And I figured it was that you don't recompile everything every time you make a change. You probably have an army of foo.o object files sitting unchanged for long periods of time. </div><div class="">And <a href="http://netstyle.ch" class="">netstyle.ch</a> being <a href="http://netstyle.ch" class="">netstyle.ch</a> they can compile their own Cog vm, which they probably have done.</div><div class="">So, again, how long has it been since you re-compiled the plugin sources? Any answer you could give to this question will no doubt prove extremely illuminating to me. </div><div class=""><br class=""></div><div class="">Thanks in advance, </div><div class="">Chris </div><div class=""><br class=""></div><div class=""><br class=""></div><div class="">[1] ProvidedTCPSocketType </div><div class=""><a href="http://squeakvm.org/cgi-bin/viewvc.cgi/squeak/branches/Cog/platforms/unix/plugins/SocketPlugin/sqUnixSocket.c?revision=3040&view=markup" class="">http://squeakvm.org/cgi-bin/viewvc.cgi/squeak/branches/Cog/platforms/unix/plugins/SocketPlugin/sqUnixSocket.c?revision=3040&view=markup</a></div><div class="">[2] </div><div class=""><a href="http://lists.squeakfoundation.org/pipermail/squeak-dev/2014-July/179015.html" class="">http://lists.squeakfoundation.org/pipermail/squeak-dev/2014-July/179015.html</a></div><div class=""><br class=""></div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On Jan 1, 2015, at 11:28 PM, Eliot Miranda <<a href="mailto:eliot.miranda@gmail.com" class="">eliot.miranda@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class="">...at <a href="http://www.mirandabanda.org/files/Cog/VM/VM.r3205/" class="">http://www.mirandabanda.org/files/Cog/VM/VM.r3205/</a>.<div class=""><br class=""></div><div class="">Happy New Year!<br class=""><div class=""><br class=""></div><div class=""><div class="">CogVM source as per VMMaker.oscog-eem.1008/r3205<br class=""></div><div class=""><br class=""></div><div class="">Send cannotReturn for sideways return attemps when there's an unwind-protect.</div><div class="">Old code would erroneously answer unwind-protect even if home could'nt be found.</div><div class=""><br class=""></div><div class="">e.g. This should raise cannot return:</div><div class=""><br class=""></div><div class=""><span class="" style="white-space:pre"> </span>| b |</div><div class=""><span class="" style="white-space:pre"> </span>b := [ ^ 42 ].</div><div class=""><span class="" style="white-space:pre"> </span>[ [b value] ensure: [1] ] fork.</div><div class=""><span class="" style="white-space:pre"> </span>Processor yield</div><div class=""><br class=""></div><div class="">just as this does:</div><div class=""><br class=""></div><div class=""><span class="" style="white-space:pre"> </span>| b |</div><div class=""><span class="" style="white-space:pre"> </span>b := [ ^ 42 ].</div><div class=""><span class="" style="white-space:pre"> </span>[ b value ] fork.</div><div class=""><span class="" style="white-space:pre"> </span>Processor yield</div><div class=""><br class=""></div><div class="">Speed up non-local return processing by using the fact that 98% of the time</div><div class="">returns are within the same page.
