buffer: fix assertion error in WeakCallback #3329
Conversation
`CallbackInfo` is now bound to `ArrayBuffer` instance, not `Uint8Array`, therefore `SPREAD_ARG` will abort with: Assertion failed: ((object)->IsUint8Array()) Make changes necessary to migrate it to `ArrayBuffer`. See: nodejs#3080 (comment)
Local<ArrayBuffer> buf = object.As<ArrayBuffer>(); | ||
ArrayBuffer::Contents obj_c = buf->GetContents(); | ||
char* const obj_data = static_cast<char*>(obj_c.Data()); | ||
CHECK_NE(obj_data, nullptr); |

@TooTallNate has mentioned how some use a zero-length buffer to keep track of things in their modules. A zero-length buffer would be nullptr
. Instead should be like:
if (obj_c.Length() > 0) CHECK_NE(obj_data, nullptr);

It's unclear to me why calling gc()
three times is required here. @indutny Sorry to pull this up from more than 3 years ago, but do you remember why?
CallbackInfo
is now bound toArrayBuffer
instance, notUint8Array
,therefore
SPREAD_ARG
will abort with:Make changes necessary to migrate it to
ArrayBuffer
