lib,src: make `StatWatcher` a `HandleWrap` #21244

addaleax · 2018-06-10T13:38:07Z

Wrapping libuv handles is what HandleWrap is there for.
This allows a decent reduction of state tracking machinery
by moving active-ness tracking to JS, and removing all
interaction with garbage collection.

Modify the `fs.watchFile()` async hooks test to be more accurate; currently, it relies on undocumented methods and the fact that they use `MakeCallback()` even though there is always a JS stack below.

LGTM — although it appears there's a related failure in the CI for the new expanded test.

Doesn't all of this fit on one line?

Not a big deal, but don't we usually use a normal owner property on the handles elsewhere?

We use a symbol in (most/all) new code.

Yes, I’d like to transition to using a single kOwner symbol for all native handles

That's a good idea (and probably what would have been done if symbols existed back in the day).

apapirovski · 2018-06-10T14:28:28Z

@addaleax could you elaborate on the commit message for the test change? unwatchFile is documented so it seems like the new version is using undocumented API (stop on the returned object)?

addaleax · 2018-06-10T14:47:35Z

@apapirovski Sorry, overlooked the possibility of using unwatchFile. I fixed that + switched away from using test files as the watch paths because that made the test unreliable in this form when run in parallel

Updates LGTM.

test/async-hooks/test-statwatcher.js

-                 'watcher1: when unwatched first file');
-checkInvocations(statwatcher2, { init: 1 },
-                 'watcher2: when unwatched first file');
+setTimeout(() => fs.writeFileSync(file1, 'foo++'), 10);


Could this be setImmediate or is that unreliable?

If we can't use that, shouldn't we be using the platform timeout modifier?

So… the reason for this is that the stat watcher itself internally itself uses file system requests + timeouts. In order to witness a change, the write needs to hit a spot after the initial internal stat request has completed, but that’s timing that we can’t really track.

I’ve updated to use common.platformTimeout(100).

test/sequential/test-fs-watch.js

-    code: 'ERR_ASSERTION'
-  });
-  oldhandle.stop(); // clean up
-}


Does the removal of this test case mean that we have to make the change semver-major? A lot of projects out there use the “tested = supported” rule.

@TimothyGu The reason for this change is that the stop method on the handle itself is gone now. You could consider this a breaking change, but everything that has changed is two layers of undocumented internals deep.

Also, the reason for this particular test here was to make sure that the native stop method would not crash with a segfault in the case of an invalid receiver, not for checking behaviour of the watcher API itself.

Nice work! Looks much cleaner now!

test: improve statwatcher async_hooks test

3602ffc

Modify the `fs.watchFile()` async hooks test to be more accurate; currently, it relies on undocumented methods and the fact that they use `MakeCallback()` even though there is always a JS stack below.

lib,src: make StatWatcher a HandleWrap

e017a83

Wrapping libuv handles is what `HandleWrap` is there for. This allows a decent reduction of state tracking machinery by moving active-ness tracking to JS, and removing all interaction with garbage collection. Refs: nodejs#21093
