V8 | Embedded JavaScript Engine for R | Runtime Evironment library

I still don't know why this started failing all of a sudden but I have resolved the problem by updating node-sass to version 6.0.1.

I'm using Mac M1 and I've just upgraded to Node 14.17.6LTS.

An interesting choice, given that Node 16 officially introduced M1 support.

no member named 'GetContents' in 'v8::ArrayBuffer'

See this doc. In short, GetContents was replaced by GetBackingStore in late 2019. Being a compatibility layer, nan adapted to this in early 2020.

So you'll probably have to ensure that the versions of all involved packages (Node, nan, electron, ...) match each other (in the sense of having been released around the same time and targeting each other).

There are two issues here:

1. Oracle Database is not supported on ARM processors, only Intel. See here: https://github.com/oracle/docker-images/issues/1814
2. Oracle Database Docker images are only supported with Oracle Linux 7 or Red Hat Enterprise Linux 7 as the host OS. See here: https://github.com/oracle/docker-images/tree/main/OracleDatabase/SingleInstance

Oracle Database ... is supported for Oracle Linux 7 and Red Hat Enterprise Linux (RHEL) 7. For more details please see My Oracle Support note: Oracle Support for Database Running on Docker (Doc ID 2216342.1)

The referenced My Oracle Support Doc ID goes on to say that the database binaries in their Docker image are built specifically for Oracle Linux hosts, and will also work on Red Hat. That's it.

Linux being what it is (flexible), lots of people have gotten the images to run on other flavors like Ubuntu with a bit of creativity, but only on x86 processors and even then the results are not guaranteed by Oracle: you won't be able to get support or practical advice when (and it's always when, not if in IT) things don't work as expected. You might not even be able to tell when things aren't working as they should. This is a case where creativity is not particularly rewarded; if you want it to work and get meaningful help, my advice is to use the supported hardware architecture and operating system version. Anything else is a complete gamble.

The Docker documentation has this list:

Heroku switched the default Node from 14 to 16 in Dec 2021 for the Ruby buildpack .

Heroku updated the heroku/ruby buildpack Node version from Node 14 to Node 16 (see https://devcenter.heroku.com/changelog-items/2306) which is not compatible with the version of Node Sass locked in at the Webpack version you're likely using.

To fix it do these two things:

1. Specify the 14.x Node version in package.json.

are small integers pooled or not?

They are not (at least not right now). That said, this is a small implementation detail and could be done either way: it would totally be possible to use the constant pool for Smis. I suppose the decision to build special machinery for Smis (instead of reusing the general-purpose constant pool) was made because things turned out to be more efficient that way.

it is not worth it pooling small integers if sizeof(int) < sizeof(int *)

The details are different (a Smi is not an int, and constant pool slots are referenced by index rather than C++ pointer), but this reasoning does go in the right direction: avoiding indirections can save time and memory.

are smis also allocated on the heap?

Yes, everything is allocated on the heap. The stack is only useful for temporary (and sufficiently small) things; that's largely unrelated to the type of thing.

The "trick" of Smis is that they're not stored as separate objects: when you have an object that refers to a Smi, such as let foo = {smi: 42}, then the value 42 can be smi-encoded and stored directly inside the "foo" object (whereas if the value was 42.5, then the object would store a pointer to a separate "HeapNumber"). But since the object is on the heap, so is the Smi.

@DanielCruz

What I understand [...] is that constant small integers are pooled. Variable small integers are not.

Nope. Any literal that occurs in source code is "constant". Whether you use let or const for your variables has nothing to do with this.

Like @Douglas Roos said in comments,

It seems that you have problems with peer dependencies, if you just set your npm to use legacy dependency logic to install your packages you will solve the problem.

Just add to your Dockerfile this setting before running npm install:

It's discussed in the documentation. Just import serverTimestamp.
