Why go runtime.newstack allocation is much more cheaper than allocating same size variable on the heap?

Asked 2021-Mar-18 at 18:19

I'm trying to understand some internals of Go. But one thing I can't wrap my head around is how goroutines' stack increases.

I see go using runtime.morestack to allocate new stack and then copy it to newly created area. Although, how it differs from heap allocation?

More precisely: why function stack() works almost ten times faster than function heap()?

First of all, as @kostix said there is only one stack grow so benchmark is not the right tool to those measurments. I tried to measure single call of stack() and heap() functions but still got unexpected results: 115ns vs 15us.

So I started from the top and find out what compiler is indeed optimizing my code and removing stack allocation completly. There is a call of stackit(), but no stack allocations.

I rewrote example and add a prints to find a moments of stack grow.

In your recursive fragment, you don't return before the base bits. So after the second jal dragon, your code falls through to the base scenario, which is wrong by any account. By that time, t1 no longer contains the direction variable - it's been multiplied by four. In the base, the code tries to resolve t1 as if it still was the direction and faults.

You are overflowing the Lua stack by continuously generating new Lua threads and leaving its Lua objects on stack.

lua_newstack() not only returns a pointer to lua_State structure, it also leaves a value of type LUA_TTHREAD on a stack in your L state. You should either accommodate the Lua stack accordingly, or manage returned Lua threads in some other way.

Quick and dirty "fix" would be to call lua_checkstack(L, 10); right before your Lstack.push(lua_newthread(L)); line. It allows your code to run as is, but the stack would continuously grow. Instead you should grab the new thread object off the stack and put it in some Lua table until the time comes for it to be deleted.

Two problems:

Your code takes a copy of the Stack, breaking nesting
Your code tries to return an ostream& as if it were a Stack, breaking compilation (well, maybe; you didn't deem us worthy of seeing its definition)

I'd guess you meant to write the following:
