# Libs Meeting 2024-05-15 ###### tags: `Libs Meetings` `Minutes` **Meeting Link**: https://meet.jit.si/rust-libs-meeting-ujepnbwg2lzqgt6wvrndwimi **Attendees**: ... ## Agenda - Triage - Anything else? ## Triage ### FCPs 1 rust-lang/rust T-libs FCPs - merge rust.tf/115746 *Print thread ID in panic message if thread name is unknown* - (3 checkboxes left) [m-ou-se (1)](https://rfcbot.rs/fcp/m-ou-se), [the8472 (1)](https://rfcbot.rs/fcp/the8472), [joshtriplett (1)](https://rfcbot.rs/fcp/joshtriplett) ### (Nominated) rust.tf/124032 *Replace sort implementations* Looks good, but regressions for html5ever and clap are significant. Regressions all seem to be in llvm. Request some deeper look into what is happening there. ### (Nominated) rust.tf/125011 *Add opt\-for\-size core lib feature flag* Josh: No objection to the concept, but I'd be very, very hesitant to add a large number of alternative algorithm implementations. (And if we ever want to support this option in any stable way, I think we'd need to run the testsuite on a version compiled that way, to make sure that the alternatives work.) Mara: Happy with the PR, if it also enables the feature on one of the CI testers. ### (Nominated) rust.tf/125060 *Expand documentation of PathBuf, discussing lack of sanitization* Mara: Don't think we can change set_file_name. Panicking on set_extension might work. Mara: Happy to merge this docs PR. The 8472: Deprecate these? Mara: Deprecate all of Path lol ### (Nominated) rust.tf/125070 *Panic if \`PathBuf::set\_extension\` would add a path separator* Josh: Merge this? And then edit 125060 to take this into account. FCP. ### (Regressions) rust.tf/119560 *\`cargo test\` performance regression on Windows on version 1.75.0* ### (Regressions) rust.tf/53340 *Performance regression in tight loop since rust 1.25* ### (Regressions) rust.tf/112180 *assertion failed: key as usize != KEY\_SENTVAL in DragonFly BSD* ### (Regressions) rust.tf/124216 `P-medium` *Performance regression: rustc failed to optimize \`\_mm256\_avg\_epu8\` after 1.75.0* ## Actions - [ ] Reply to all issues/PRs discussed in this meeting, or add them to the [open action items](https://hackmd.io/Uehlc0qUQfWfvY1swYWRgQ). _Generated by [fully-automatic-rust-libs-team-triage-meeting-agenda-generator](https://github.com/rust-lang/libs-team/tree/main/tools/agenda-generator)_
