Hide userland threads by default - #2083
Conversation
This commit changes a long‑standing default, and might be one of the most visible changes yet. Userland threads were originally shown to help users learn about NPTL/LWP at a time when these threading models were still rare, but that historical purpose has since long faded. Modern applications routinely spawn large numbers of lightweight threads, and exposing all of them by default has become more distracting than informative. With NPTL now widely adopted and commonly used, hiding userland threads provides a cleaner, more relevant process view. The updated default enables hide_userland_threads, reducing clutter while still allowing users to inspect userland threads explicitly when needed. Please note that this change only affects new setups while existing configurations are kept unchanged unless they are manually adjusted.

Makes sense :) I toggle them often, depending on whether I'm interested in the inner workings of some processes or just want an overall look of the system. Here's an unsolicited wild idea that occurred to me the other day: what if clicking the thr and kthr counters of the Meter toggled their display on and off? I don't think anything in Meters is clickable yet (at least they weren't in my days), but seeing the thread gray out made this thought spring to my mind the other day. Cheers, and keep up the amazing work! <3 |
