I decided to implement some "shared object manager" based on the ideas from [WICBS18], which is kind of a "manually triggered garbage collector" in the end. And hey, it works! 🥳 <a href="https://github.com/Zirias/poser/blob/master/src/lib/core/sharedobj.c" rel="nofollow noopener" translate="no" target="_blank">https://github.com/Zirias/poser/blob/master/src/lib/core/sharedobj.c</a>[MS96] <a href="https://dl.acm.org/doi/10.1145/248052.248106" rel="nofollow noopener" translate="no" target="_blank">https://dl.acm.org/doi/10.1145/248052.248106</a> [WICBS18] <a href="https://www.cs.rochester.edu/u/scott/papers/2018_PPoPP_IBR.pdf" rel="nofollow noopener" translate="no" target="_blank">https://www.cs.rochester.edu/u/scott/papers/2018_PPoPP_IBR.pdf</a><a href="https://mastodon.bsd.cafe/tags/coding" class="mention hashtag" rel="nofollow noopener" target="_blank">#coding</a> <a href="https://mastodon.bsd.cafe/tags/c" class="mention hashtag" rel="nofollow noopener" target="_blank">#c</a> <a href="https://mastodon.bsd.cafe/tags/c11" class="mention hashtag" rel="nofollow noopener" target="_blank">#c11</a> <a href="https://mastodon.bsd.cafe/tags/atomics" class="mention hashtag" rel="nofollow noopener" target="_blank">#atomics</a>

I *think* I can spot it in the pseudo code from the paper I used[1], see screenshot. Have a look at lines E7 and E8. Suppose the thread executing this is suspended after E7 for a "very long time". Now, some dequeue operation from some other thread will eventually dequeue whatever "Q->Tail" was pointing to, and then free it after consumption. Our poor thread resumes, checks the pointer already read in E6 for NULL successfully, and then tries a CAS on tail->next in E9, which is unfortunately inside an object that doesn't exist any more .... If the CAS succeeds because at this memory location happens to be "zero" bytes, we corrupted some random other object that might now reside there. 🤯 Please tell me whether I have an error in my thinking here. Can it be ....? 🤔 Meanwhile, after fixing and improving lots of things, I checked the alternative implementation using <a href="https://mastodon.bsd.cafe/tags/mutexes" class="mention hashtag" rel="nofollow noopener" target="_blank">#mutexes</a> again, and surprise: Although it's still a bit slower, the difference is now very very small. And it has the clear advantage that it never crashes. 🙈 I'm seriously considering to drop all the lock-free <a href="https://mastodon.bsd.cafe/tags/atomics" class="mention hashtag" rel="nofollow noopener" target="_blank">#atomics</a> stuff again and just go with mutexes.[1] <a href="https://dl.acm.org/doi/10.1145/248052.248106" rel="nofollow noopener" translate="no" target="_blank">https://dl.acm.org/doi/10.1145/248052.248106</a>

Felix Palmen :freebsd: :c64:I now experimented with different ideas how to implement the <a href="https://mastodon.bsd.cafe/tags/lockfree" class="mention hashtag" rel="nofollow noopener" target="_blank">#lockfree</a> <a href="https://mastodon.bsd.cafe/tags/queue" class="mention hashtag" rel="nofollow noopener" target="_blank">#queue</a> for multiple producers and multiple consumers. Unsurprisingly, some ideas just didn't work. One deadlocked (okaaay ... so it wasn't lockfree) and I eventually gave up trying to understand why.The "winner" so far is only "almost lockfree", but at least slightly improves performance. Throughput is the same as with the simple locked variant, but average response times are 10 to 20% quicker (although they deviate stronger for whatever reason). Well, that's committed for now:<a href="https://github.com/Zirias/poser/commit/4f2f80a8266e4762e04ead2b802e7a7c1b55090b" rel="nofollow noopener" translate="no" target="_blank">https://github.com/Zirias/poser/commit/4f2f80a8266e4762e04ead2b802e7a7c1b55090b</a><a href="https://mastodon.bsd.cafe/tags/C11" class="mention hashtag" rel="nofollow noopener" target="_blank">#C11</a> <a href="https://mastodon.bsd.cafe/tags/atomics" class="mention hashtag" rel="nofollow noopener" target="_blank">#atomics</a>
