test/sequential/test-fs-watch.js hanging on OS X

[evanlucas]

Possibly related: #1275

It is hanging indefinitely every other run or so

That's odd. It doesn't hang in CI ever, it seems. A stress test might be interesting to see what that uncovers. What version of OS X are you running? And how are you testing? make test or ./node test/sequential/test-fs-watch.js or what? And you're using something close to master presumably?

It hangs every other run if run using ./node test/sequential/test-fs-watch.js.

make test hangs 1/4 of the time. (roughly). This is running directly on master as of now

Hm.. I haven't been able to reproduce with the same machine setup, building master, and running the test ~50 times.

Here is a small stress test on it https://ci.nodejs.org/job/node-stress-single-test/nodes=osx1010/104/console

I wonder if this is 10.11 specific?

https://github.com/nodejs/node/blob/master/test/sequential/test-fs-watch.js#L39-L52 is the block that is not being called. The event is not being emit.

Closing as I am not seeing this issue anymore. I will reopen if it surfaces again.
