Felix Palmen :freebsd: :c64:<p>Oh boy, I have a lead! And it's NOT related to <a href="https://mastodon.bsd.cafe/tags/TLS" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>TLS</span></a>. I finally noticed another pattern: <a href="https://mastodon.bsd.cafe/tags/swad" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>swad</span></a> only <a href="https://mastodon.bsd.cafe/tags/crashed" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>crashed</span></a> when running as a <a href="https://mastodon.bsd.cafe/tags/daemon" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>daemon</span></a>. The daemonizing wasn't the problem, but the default logging configuration attached to it: "fake async", by letting a <a href="https://mastodon.bsd.cafe/tags/threadpool" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>threadpool</span></a> job do the logging.</p><p>Forcing THAT even when running in foreground, I can finally reproduce a crash. And I wouldn't be surprised if that was actually the reason for crashing "pretty quickly" with <a href="https://mastodon.bsd.cafe/tags/LibreSSL" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>LibreSSL</span></a> (and only rarely with <a href="https://mastodon.bsd.cafe/tags/OpenSSL" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OpenSSL</span></a>), I mean, something going rogue in your address space can have the weirdest effects.</p>

Felix Palmen :freebsd: :c64:<p>Still working on <a href="https://mastodon.bsd.cafe/tags/swad" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>swad</span></a>, and currently very busy with improving quality, most of the actual work done inside my <a href="https://mastodon.bsd.cafe/tags/poser" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>poser</span></a> library.</p><p>After finally supporting <a href="https://mastodon.bsd.cafe/tags/kqueue" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>kqueue</span></a> and <a href="https://mastodon.bsd.cafe/tags/epoll" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>epoll</span></a>, I now integrated <a href="https://mastodon.bsd.cafe/tags/xxhash" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>xxhash</span></a> to completely replace my previous stupid and naive hashing. I also added a more involved <a href="https://mastodon.bsd.cafe/tags/dictionary" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>dictionary</span></a> class as an alternative to the already existing <a href="https://mastodon.bsd.cafe/tags/hashtable" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>hashtable</span></a>. While the hashtable's size must be pre-configured and collissions are only ever resolved by storing linked lists, the new dictionary dynamically nests multiple hashtables (using different bits of a single hash value). I hope to achieve acceptable scaling while maintaining also acceptable memory overhead that way ...</p><p><a href="https://mastodon.bsd.cafe/tags/swad" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>swad</span></a> already uses both container classes as appropriate.</p><p>Next I'll probably revisit poser's <a href="https://mastodon.bsd.cafe/tags/threadpool" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>threadpool</span></a>. I think I could replace <a href="https://mastodon.bsd.cafe/tags/pthread" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>pthread</span></a> condition variables by "simple" <a href="https://mastodon.bsd.cafe/tags/semaphores" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>semaphores</span></a>, which should also reduce overhead ... </p><p><a href="https://github.com/Zirias/swad" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="">github.com/Zirias/swad</span><span class="invisible"></span></a></p><p><a href="https://mastodon.bsd.cafe/tags/c" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>c</span></a> <a href="https://mastodon.bsd.cafe/tags/coding" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>coding</span></a></p>
