RP: it might be tricky to write one script that will work on all systems (e.g. on some dmesg requires root) RP: AB-helper might be useful too. it could be that disk cache wiping might be an issue MichaelH: only some of the workers have that at this point RP: could you give us a list of which workers have that enabled? maybe we will see a correlation MichaelH: sure PaulB: pr-serv changes going into the next release RP: yes, i was under the impression we’d need a bit more time for it PaulB: yes, i’m not 100% available at the moment RP: no problem, it’ll reduce the pressure PaulB: agreed, getting it in too close to the release could be risky RP: i’m looking at removing a bunch of code related to dynamic hashing. i’m pretty sure it’s not being used anymore, but need to double-check it RP: there are ~6 reproducibility issues, have patches for them (submitted upstream) including: - ignoring the Go issue - i think Bruce is close to getting perf working - meson python compiled header issue - ovmf hard-coded path issue (Ross is looking into it) strange build system (edk2) - ruby-docs Randy: there’s a valgrind release in the works, but we can wait for it Ross: there’s grub as well (CVEs) RP: do we have any timeline? Randy: upstream says “…in a matter of days…” 8 days ago RP: i won’t block -m3 on it RP: would prefer to not upgrade valgrind too close to a release (history of causing ptest issues) AlexB: are the ptest issues performance-related? RP: not necessarily, just that we often get issues
