Remove cpu_features dependency

[WeeJeWel]

The cpu_features dependency does not install on M1 Macs.

We use homey -> dockerode -> docker-modem -> ssh2 -> cpu_features in our module, which is installed using npm i -g homey, as usual.

Unfortunately, all M1 Mac users get a big error and they think the install failed.

[PRR24]

With no disrespect to anyone offering their-written software for free, please kindly do not make a widely used and important module ssh2 dependent on any clearly undermaintained packages like cpu-features.

[mscdex]

@PRR24 I'm not sure how you arrived at "clearly undermaintained" for cpu-features. Also, cpu-features is an optional dependency that it no way affects the successful installation of ssh2.

[WeeJeWel]

Also, cpu-features is an optional dependency that it no way affects the successful installation of ssh2.

@mscdex While that is technically true, unfortunately NPM installs it by default and shows a big fat warning when it fails.

[PRR24]

@PRR24 I'm not sure how you arrived at "clearly undermaintained" for cpu-features. Also, cpu-features is an optional dependency that it no way affects the successful installation of ssh2.

Well, mscdex/cpu-features#4 you explicitly state that you have not have time to push the 0.0.3 update in last 23 days. It is hard to call a library that fails to install on Linux in standard Node environment for weeks, anything but undermaintained.

Again, with no disrespect -- while such latency is IMO fully acceptable for the cpu-features library, it is a problem for the library as important and widely used as ssh2.

And IMO it does not matter, if the library is optional of not, ssh2 is a library that because of its nature should shine and scream of quality and reliability and current situation undermines it a lot.

I kindly ask you to take my input not as a mindless rant, but a constructive criticism. I do appreciate your work.

@PRR24 maybe try apologising instead. Calling someone’s open source work “undermaintained” is downright rude. The words “With no disrespect” are not a magic spell that makes being rude ok.

@WeeJeWel cpu-features is included for good reasons. The error message is only a problem if someone doesn’t read the all-caps SKIPPING OPTIONAL DEPENDENCY npm helpfully prints. And as mscdex pointed out, this is just a temporary inconvenience that will be solved once the upstream library adds support for your fancy new Mac.

Failure to build the cpu_features dependency can cause CI builds to fail, even though npm knows the dependency is optional. If you're using electron-build, turning off "build dependencies from source" is an effective temporary workaround. In package.json:

    "build": {
		...
        "buildDependenciesFromSource": false,
        ...
    },

This is an issue for me because when I try to create a lambda it fails due to this package having unexpected syntax.

See what happens if you create a project, add this package as a dependency, create a serverless.yml file, and run sls deploy. It breaks with Unexpected Syntax due to this package.

[mscdex]

@bmcilw1 I don't see the connection between a vague "unexpected syntax" error and ssh2's dependency on cpu-features

[thebrianbug]

I didn't specify, but I can recreate it shortly.

UPDATE - here we go.

First, I create a new node project and add ssh2 and sls as dependencies.

Then, I run npm install. I get some errors on Mac.

So from that, I know that this package has not been installed correctly. I then try to create a deployment with sls deploy and was getting an "unexpected token" error. Now that I try again, it somehow seems to be working again. I still get the build error thrown above, but not the unexpected token error. So maybe this was a red herring, or weird file state on my machine somehow? Sorry if that's the case 🤷

UPDATE 2 - It seems like I can't recreate the issue. I'm assuming this was due to some corrupt file state, though it WAS still throwing the same error even after deleting the node_modules dir. Thanks for the response.

@priceaj Looks like other people have the same issues with ssh2 that we have.

[mscdex]

For those who are willing to test a new prebuilt addon system for me that may help alleviate some of the concerns raised (namely needing to have a build environment available for most common platforms), see #1114.

The issue in cpu_features was fixed in 0.7.0 just released: mscdex/cpu-features#7
