Add support for Error::Fatal by kfarnung · Pull Request #70 · nodejs/node-addon-api

kfarnung · 2017-06-30T00:13:46Z

Added static method Error::Fatal to invoke napi_fatal_error
Added node_internals.cc/h to shim missing internal functions
Added a test for Error::Fatal

/cc @digitalinfinity @jasongin @gabrielschulhof

Ignore the changes to node_api.cc/h for now as they include the in-progress changes from nodejs/node#13971. I also need to use napi_fatal_error in a few locations throughout the wrapper code, but haven't gotten there yet.

src/node_internals.h

Can you put a comment in here explaining that this is not the real, complete "node_internals", but just a shim for building node_api.cc outside of node?

bnoordhuis · 2017-06-30T09:11:41Z

napi-inl.h

Suggestion: wrap this in a do { ... } while so that if (...) NAPI_FATAL_IF_FAILED(...); else ... does the right thing.

bnoordhuis · 2017-06-30T09:14:03Z

src/node_api.cc

Style: indent line continuations by four spaces, not two.

bnoordhuis · 2017-06-30T09:23:58Z

src/node_api.cc

Style: wrapper_template (snake_case, not camelCase, for locals.)

Substance: creating an ObjectTemplate every time leaks memory. V8 caches them internally and it doesn't put an upper bound or a lifetime on elements in the cache. Create a single ObjectTemplate and reuse that.

Hmm ... we do this upstream as well.

bnoordhuis · 2017-06-30T09:25:19Z

src/node_api.cc

Can you use the Maybe overloads here?

bnoordhuis · 2017-06-30T09:31:55Z

src/node_internals.h

None of the code in this file is (c) Joyent, it's all (c) yours truly. You can leave out the copyright boilerplate or reduce it to just 'Node contributors.'

The same applies to the preceding file, I think: it's a mix of code authored by @mscdex and me (and maybe @indutny.)

Thanks @bnoordhuis, I was looking for some guidance here. I'll change the copyright headers.

bnoordhuis · 2017-06-30T09:32:49Z

test/error.js

Style: 4 space indent for line continuations.

V8 caches and does not subsequently release `ObjectTemplate` instances. Thus, we need to store the `ObjectTemplate` from which we derive object instances we use for `napi_wrap()` and function/accessor context in a persistent in the `napi_env`. nodejs/node-addon-api#70 (comment)

@kfarnung Is this ready to merge? It looks like you've addressed @bnoordhuis's feedback.

kfarnung · 2017-07-12T22:26:23Z

I was waiting on the upstream change (nodejs/node#13971) to land before trying to get this merged.

mhdawson · 2017-07-14T14:46:57Z

I guess this now needs to be rebased to remove the changes to the node files.

kfarnung · 2017-07-14T16:08:25Z

Yup, I'll take care of that momentarily.
