Lucy::...ockErr(3pm)

✨ Lucy::Store::LockErr — the vibe check failed bestie 💅

okay so this is a page from the User Contributed Perl Documentation manual, and it's giving very specific — it's all about one tiny exception class. Lowkey iconic of it. 🎀

---

🌸 NAME 🌸

Lucy::Store::LockErr — the Lock exception. That's it, that's the whole name section. Short. Punchy. Main character energy. 👑

---

💖 SYNOPSIS 💖

Here's how you actually catch this thing, bestie — copy it exactly, no cap:

    while (1) {
        my $bg_merger = eval {
            Lucy::Index::BackgroundMerger->new( index => $index );
        };
        if ( blessed($@) and $@->isa("Lucy::Store::LockErr") ) {
            warn "Retrying...\n";
        }
        elsif (!$bg_merger) {
            # Re-throw.
            die "Failed to open BackgroundMerger: $@";
        }
        ...
    }

So the way this works: you wrap the thing in eval, then vibe check $@ with blessed() and isa("Lucy::Store::LockErr") — if it is that, you just warn "Retrying...\n" and go around again like nothing happened. 🌀 If it's not that, and $bg_merger is falsy, you # Re-throw. it with die "Failed to open BackgroundMerger: $@"; because you are not about to swallow someone else's error. periodt.

🦋 DESCRIPTION 🦋

LockErr is a subclass of Err, and it means a file locking problem occurred. That's the whole tea. ☕ When the lock situation goes sideways, this is the exception that shows up to tell you about it. Fr fr.

👑 INHERITANCE 👑

Lucy::Store::LockErr isa Clownfish::Err isa Clownfish::Obj.

The whole family tree, laid out like a group chat: LockErr → Clownfish::Err → Clownfish::Obj. Three generations of absolute royalty. 🌈✨
