🌸 Munin::Common::Timeout 🌸

okay bestie, welcome to Munin:...imeout(3pm) — it's a page from the User Contributed Perl Documentation collection, and it's literally about running code with a timeout. yes. that's the whole vibe. 💅

---

✨ NAME ✨

Munin::Common::Timeout — run code with a timeout. may nest. 🫶

---

✨ SYNOPSIS ✨

like, here's the whole thing in action:

use Munin::Common::Timeout;

do_with_timeout(50, sub {
    # ...
       do_with_timeout(5, sub {
               # ...
               # ...
       });
    # ...
});

see how it's all tucked inside itself? nesting is the moment. 🪆✨

---

✨ DESCRIPTION ✨

ngl this page is short and it knows it. it just wants you to also go look at Time::Out and Sys::AlarmCall. that's it. that's the description. 👑

---

✨ SUBROUTINES ✨

💖 do_with_timeout

my $finished_with_no_timeout = do_with_timeout($seconds, $code_ref)
    or die "Timed out!";

so here's the tea 🍓 — this runs $block with a timeout of $seconds. if the block finishes within the timeout, you get its return value back. slay.

but if the timeout hits while the code is still going, it halts it and returns undef. 💀

NB, and this part is important bestie: every $code_ref should return something defined, otherwise the caller literally cannot tell whether a timeout happened. like, undef is the timeout signal. don't hand out undef for free. 🚨

calls to do_with_timeout() can be nested, so go as deep as you want. and any exceptions raised by $block are propagated — they get passed right on up, no swallowing, no cover-ups. 🌈

---

that's genuinely the whole page, you're so done, go forth and time things out responsibly 💜

— cute lil sign-off: this was perl v5.42.3, dated 2026-09-30, and the manual name is Munin:...imeout(3pm). bye bestie!! 🎀🦋✨
