16:00:34 <fjahr> There are no pre-proposed meeting topics this week. Any last minute ones to add?

16:01:59 <brunoerg> hi
16:02:15 <fjahr> Let's do the WGs
16:02:17 <fjahr> #topic QA WG Update (brunoerg)
16:02:39 <brunoerg> Hi! I ran a mutation analysis for the silent payments PR and got a positive feedback about the findings and many mutants were addressed. Now that the implementation is on master, I re-ran the analysis for sp code as part of the weekly run. It got 100% of mutation score (that's perfect) - I will probably run a full analysis to check if there is any leftover. Results can be seen at: https://secp256k1.space
16:03:01 <nervana21> hi
16:03:03 <brunoerg> I also re-ran the mutation analysis for src/script/interpreter.cpp, since it's critical code I generated all the possible mutants. I got over 1000 mutants for this file which only 80 of them survived. There are some PRs adding more test cases for the interpreter which I hope we will soon have full coverage of them.
16:03:23 <brunoerg> Naiyoma is helping me to test the parallelization of the analysis, I hope to get it ready soon, it will make our mutation workflow faster and more practical.
16:03:53 <purpleKarrot> hi
16:03:58 <darosior> hi
16:04:22 <brunoerg> Also, I appreciate feedback from kernel people in https://github.com/bitcoinfuzz/bitcoinfuzz/pull/647. the idea is doing differential fuzzing between the kernel and the Core's internals.
16:04:26 <brunoerg> That's all
16:04:46 <fjahr> cool, thanks!
16:04:51 <fjahr> #topic QML GUI WG Update (johnny9dev)
16:05:34 <johnny9dev> continue to work on the staging branch and fixing issues
16:05:42 <johnny9dev> thats all for now
16:05:59 <fjahr> #topic Benchmarking WG Update (l0rinc, andrewtoth)
16:06:07 <l0rinc> A few of the quadratic iteration fixes were merged, #36096 is similar, review would be appreciated.
16:06:09 <corebot> https://github.com/bitcoin/bitcoin/issues/36096 | rpc: avoid quadratic JSON construction when keys are unique by l0rinc · Pull Request #36096 · bitcoin/bitcoin · GitHub
16:06:16 <l0rinc> And as mentioned yesterday, #36000 was tuned a bit more, now a reindex-chainstate is often >50% faster.
16:06:19 <corebot> https://github.com/bitcoin/bitcoin/issues/36000 | validation: prefetch blocks while connecting by l0rinc · Pull Request #36000 · bitcoin/bitcoin · GitHub
16:06:28 <l0rinc> IBD is probably internet bandwidth bounded now, will experiment with parallel undo/block flushes to see if it helps.
16:06:50 <l0rinc> Will also profile a neutered validation-less and UTXO-less node to see the remaining bottlenecks.
16:07:04 <l0rinc> That's it from me, thanks
16:07:19 <fjahr> #topic Kernel WG Update (sedited)
16:07:27 <sedited> Been getting some good review on #35641 . Also had some external projects say they would be interested in its capability.
16:07:30 <corebot> https://github.com/bitcoin/bitcoin/issues/35641 | kernel: Add script evaluation tracer by sedited · Pull Request #35641 · bitcoin/bitcoin · GitHub
16:08:09 <sedited> and will circle around to the things request in the pr brunoerg linked before
16:08:14 <sedited> that's all
16:08:42 <fjahr> Anything else to discuss? Possibly the release?
16:09:37 <sedited> there's still a few items in the milestone: https://github.com/bitcoin/bitcoin/milestone/84
16:09:51 <sedited> would be good to get them in before branch-off.
16:10:58 <fjahr> Please review! Anything else?
16:11:42 <pinheadmz> Im getting lots of agent findings in the new HTTP
16:11:54 <pinheadmz> im triaging solutions before branch off
16:12:18 <pinheadmz> so just keep em coming.
