@nodejs/platform-smartos

My team will be taking a look at this.

Hi @targos, I'm struggling to find where this is coming from - GitHub search across the entire nodejs and v8 organisations show no code matches for malloc_usable_size(). It's not something we have in SmartOS, and many other platforms don't have it either, so the fix should be pretty straight-forward, I just can't figure out where it's actually being used.

I'd be more than happy to submit a fix for it if you could help me get up to speed on which repositories that test job is pulling from. Thanks!

In the V8 repo: https://github.com/v8/v8/blob/50504b168d2c364d49e3332cbd934dc60a4bfad8/src/base/platform/memory.h#L117-L118

Introduced by https://chromium-review.googlesource.com/c/v8/v8/+/3858226

In this repo (canary is updated every day so the commit is ephemeral):

node-v8/deps/v8/src/base/platform/memory.h

Lines 117 to 118 in 4e97ad7

    
           #else   // POSIX. 
        
             return malloc_usable_size(ptr);

Ah, ok, thanks! Looks like GitHub search just completely doesn't work.

The fix looks straight-forward (add V8_OS_SOLARIS to the exclusion list for V8_HAS_MALLOC_USABLE_SIZE on line 26, similar to AIX) but I assume I'll need to get this through the v8 contribution process first.

I'm floating a patch for now in nodejs/node#44741 but let's keep this issue open until it's upstreamed.

@bahamat the patch still needs to be upstreamed, see nodejs/node#45118.

@bnoordhuis Ok, I'm looking into the CLA requirement. It's not clear to me that MNX is the most appropriate agent to contribute the patch, since we are not the author/copyright holder.

@targos That means you'd have to upstream it?
