Minor warning about the use of FastOneByteString.

Can we do something like DebugSealHandleScope
, i.e. actually enforce this constraint through code? E.g. a DebugDisallowJavascriptExecutionScope
that defers to V8's DisallowJavascriptExecutionScope
? (That may not be 100% equivalent to disallowing GC, but maybe it's close enough?)

Possibly? My knowledge of DebugSealHandleScope
is super rusty tho so I'm not entirely sure.

My knowledge of
DebugSealHandleScope
is super rusty tho so I'm not entirely sure.
The point is just that it's possible to at least partially implement something that mechanically prevents GC execution, which is typically better than a comment 🙂 The analogy to DebugSealHandleScope
would be that if an explicit DisallowJavascriptExecutionScope
is too expensive (it might be?), we could create a debug-only variant of it similar to how DebugSealHandleScope
is the debug-only variant of SealHandleScope
.

Yeah, it's a great idea... just would take me a bit of time to page back in the knowledge to do that ;-)

I think for now, let's get this warning comment landed and we can work on the scope impl separately?

@jasnell Not a blocker by any means, it just seems simpler that way

This could probably do with a Chromium issue as well – FastOneByteString dates from when the fast API could not access the isolate or trigger GC, so presumably this is an oversight? |
