What steps will reproduce the bug?
class Test {
private abortController = new AbortController()
public test(cb: (abortSignal: AbortSignal) => void, abortSignal: AbortSignal) {
const signal = AbortSignal.any([abortSignal, this.abortController.signal])
cb(signal)
}
}
const registry = new FinalizationRegistry((heldValue) => {
console.log(`${heldValue} has been collected`)
})
;(() => {
const test = new Test()
registry.register(test, 'test')
const abortController = new AbortController()
test.test((abortSignal) => {
abortSignal.addEventListener('abort', () => {
console.log(test)
})
}, abortController.signal)
})()
global.gc?.()
setTimeout(() => {
console.log('the end')
}, 2000)
run with node --expose-gc test.ts
How often does it reproduce? Is there a required condition?
Every time
What is the expected behavior? Why is that the expected behavior?
the output should be
test has been collected
the end
because the test object is not referenced anymore
What do you see instead?
output:
the test object is not garbage collected
Additional information
The issues seems to be caused by the cyclic dependency: test object => abortController field => abortSignal => AbortSignal.any result => cb function => test object
AbortSignal.any seems to prevent node from garbage collecting them all at once
