1781008 - Add JSContext-free variant of AutoCheckRecursionLimit

Status: RESOLVED FIXED

(Core :: JavaScript Engine, task, P1)

Description

[Tooru Fujisawa [:arai]]

js::AutoCheckRecursionLimit is used for checking stack limit inside frontend, and it uses JSContext to access JS::RootingContext::nativeStackLimit

https://searchfox.org/mozilla-central/search?q=AutoCheckRecursionLimit&path=js%2Fsrc%2Ffrontend&case=false&regexp=false

That part needs to be refactored in order to remove the JSContext dependency

The error reporting part needs bug 1773324 patches.

Comment 2

Attachment: Bug 1781008 - Part 4: Wrap WASI recursion check with JSContext and ErrorContext functions. r?bthrall!

WASI uses extra JSContext fields to track the recursion depth.
Given WASI doesn't support thread, move it to JSContext and
MainThreadErrorContext.
