fish complains it can’t read Primary Device Attribute…only when logging in #12571

> fish --version
fish, version 4.5.0

I’m running macOS 26.4.

I have not tried fish without third-party customizations, but I don’t have anything super fancy like oh-my-fish or that kind of thing.

When I reboot my Mac, I get the following in Terminal.app (but not iTerm; not sure why):

warning: fish could not read response to Primary Device Attribute query after waiting for 2 seconds. This is often due to a missing feature in your terminal. See 'help terminal-compatibility' or 'man fish-terminal-compatibility'. This fish process will no longer wait for outstanding queries, which disables some optional features.
fish_config theme choose: failed to find '[unknown]' section (implied by $fish_terminal_color_theme) in 'ayu’ theme
fish_config theme choose: hint: if your terminal does not report colors, pass --color-theme=light or --color-theme=dark when using color-theme-aware themes

I never get this warning when I hit ⌘N or ⌘T to get a new window/tab; I figure I’m only getting this warning because, when I’m logging in after a reboot, the system is absolutely hammered trying to get all my programs running again and something’s not responding in time.

I had a look at #11108. Would it be possible (not 100% sure it’d be a good idea) to extend the 2-second timeout to something moderately ridiculous, like 5 or 10 seconds?
