src,stream: use SetAccessorProperty instead of SetAccessor by jure · Pull Request #17665 · nodejs/node

jure · 2017-12-13T22:45:36Z

As per #17636's solution 1 (found in #17636 (comment)), this PR allows Object.getOwnPropertyDescriptor(process.stdin._handle.__proto__, 'bytesRead') to not throw anymore and return an object/property descriptor. However, accessing this property using process.stdin._handle.__proto__.bytesRead will still throw (as is the current case on 8.9.2+).

+
+  // Should not throw for Object.getOwnPropertyDescriptor
+  assert.strictEqual(
+    typeof (Object.getOwnPropertyDescriptor(TTY.prototype, 'bytesRead')),


You don’t need the parentheses after typeof here

👍 Removed.

This PR should also update the following files. In all of them, look for PrototypeTemplate()->SetAccessor to find which ones to replace.

node_crypto.cc
udp_wrap.cc

Ideally, we shouldn't use SetAccessor on InstanceTemplate() either, other than under exceptional circumstances. Here're two files that are easier to fix (look for SetAccessor):

node_crypto.cc
node_perf.cc

+
+  Local<Signature> signature =
+      Signature::New(env->isolate(), t);


For the person landing this commit: these two lines could be merged into a single line, which might help with readability.

👍 This used to be AccessorSignature, and was over the limit. Fixed.

+    env->isolate(),
+    GetFD<Base>,
+    Local<Value>(),
+    signature);


For the person landing this commit: for consistency the indentation should look something like:

Local<FunctionTemplate> get_fd_templ = FunctionTemplate::New(env->isolate(), GetFD<Base>, Local<Value>(), signature);

👍 Fixed, was struggling a bit with how to indent it before.

test/parallel/test-stream-base-prototype-accessors.js

 {
-  const msg = /TypeError: Method \w+ called on incompatible receiver/;
+  // Should throw instead of raise assertions
+  const msg = /TypeError: Illegal invocation/;


Even better, change all uses of msg below to TypeError, because the exact error message may differ depending on the JavaScript engine.

👍 Fixed.

TimothyGu

Almost there!

-  t->PrototypeTemplate()->SetAccessor(
+  Local<FunctionTemplate> ctx_getter_templ =
+    FunctionTemplate::New(env->isolate(),


We indent by four spaces in line continuations :)

Here and also in other C++ files.

test/parallel/test-stream-base-prototype-accessors.js

+  assert.strictEqual(
+    typeof Object.getOwnPropertyDescriptor(TTY.prototype, '_externalStream'),
+    'object'
+  );


Similar tests should exist for Object.getOwnPropertyDescriptor(crypto.SecureContext.prototype, '_external') and Object.getOwnPropertyDescriptor(crypto.Connection.prototype, '_external') where crypto = process.binding('crypto'), and Object.getOwnPropertyDescriptor(process.binding('udp_wrap').UDP.prototype, 'fd').

👍 Added.

src/node_crypto.cc

+  Local<FunctionTemplate> ctx_getter_templ =
+    FunctionTemplate::New(env->isolate(),
+                          CtxGetter,
+                          Local<Value>(),


We usually use env->as_external() for the parameter right here, so that we can get access to the Environment object in the callback itself. Again, here and below.

You mean instead of Local<Value>()?

Yes.The same also needs to be done for all other such instances, otherwise I'm fairly sure some tests will fail because of this.

Tests completed fine with just Local<Value>(), so that's a bit worrying, but it's perhaps out of the scope of this PR to add tests for that. I've now switched to env->as_external wherever it was previously used.

jure · 2017-12-14T02:20:37Z

That should be that I think! Fun stuff :)

jure · 2017-12-14T02:33:18Z

src/node_crypto.cc

+  Local<FunctionTemplate> verify_error_getter_templ =
+      FunctionTemplate::New(env->isolate(),
+                            DiffieHellman::VerifyErrorGetter,
+                            Local<Value>(),


Would env->as_external() be appropriate here as well? Or better yet, is there a place where it isn't appropriate (there are 10 places still using it)?

I guess anywhere where as_external was previously used. I'll get on it.

From a quick look: it would be appropriate at all of those places. In fact if you look at the current SetAccessor()-based code, all of them have env->as_external() for the data parameter.

TimothyGu

LGTM. The comment is optional.

TimothyGu · 2017-12-14T02:56:44Z

src/node_perf.cc

+  Local<FunctionTemplate> get_performance_entry_name_templ =
+      FunctionTemplate::New(env->isolate(),
+                            GetPerformanceEntryName,
+                            Local<Value>(),


I know they didn't use to get env->as_external(), so this should be fine. But for sake of consistency I'd rather still have env->as_external() here.

Sure, that makes sense. Done 👍

What's with the failures on CI (Windows, Linux and SmartOS)? How does one look into a failed build?

TimothyGu · 2017-12-14T05:29:35Z

The CI failures all seem to be infrastructural. I'll start a rebuild to see if the situation improves. If not we can land this as-is.

@jure We usually tend to wait a few days before applying to make sure everyone who wants to take a look at this PR got a chance to. This should get applied in a few hours.

MylesBorins · 2018-01-23T07:06:48Z

Do we want to land this on LTS? It lands cleanly on v8.x and v6.x, just unsure if we should wait a bit before landing

TimothyGu · 2018-01-23T15:46:34Z

@MylesBorins I’m +1 on backporting this.

MylesBorins · 2018-02-27T03:20:31Z

This does not land cleanly on v6.x due to the performance API not existing on that release stream. Does it still make sense to backport?

edit: landing on v8.x also broke a test, need a backport to both branches
