Hi @catlee ,
Thank you for opening this PR. This is going to be a significantly big PR and we'll have to make sure that changes are backward compatible. So before you make further changes, I'd recommend you to keep these two things in mind:

1. The interface shouldn't change. Currently the interface of BaseService#client is being changed; It now returns FaradayClient rather than HTTPClient, and
2. No functionality is lost (we'd need to carefully audit all the capabilities of HTTPClient that are being used and depended on, and make sure they are replicated in the Faraday implementation). There are a lot of other libraries which are dependent on core library and hence we'll have to be careful.

Hi @catlee , Thank you for opening this PR. This is going to be a significantly big PR and we'll have to make sure that changes are backward compatible. So before you make further changes, I'd recommend you to keep these two things in mind:

1. The interface shouldn't change. Currently the interface of BaseService#client is being changed; It now returns FaradayClient rather than HTTPClient

This is a pretty significant restriction. Many of the methods in the code pass around a client object, which is assumed to be an HTTPClient instance. I'm not sure how we can switch to another implementation without changing this contract.

Do you have any suggestions for how to resolve this? I wonder if it's possible to create an adapter for FaradayClient that makes it behave like HTTPClient...

2. No functionality is lost (we'd need to carefully audit all the capabilities of HTTPClient that are being used and depended on, and make sure they are replicated in the Faraday implementation). There are a lot of other libraries which are dependent on core library and hence we'll have to be careful.

The test suite seems very comprehensive. Are there areas of particular concern?

Hey @catlee
Sorry it's taking long for us to respond.
We generally don't allow any breaking change in our libraries; but I get your point. Let me discuss this internally and get back to you. Thank you for your patience!

@bajajneha27 Any news?

Since HTTPClient has been unmaintained for a long time, you should also consider whether this is a security issue #2348 (comment)

depending on abandonware that hasn't been touched since 2016 that handles establishing SSL connections is not secure at all

bump :(

Unfortunately, we're having bigger and bigger issues with httpclient, so it'd be great if we can have this ready.

@bajajneha27 are there any updates on this topic? The issue is indeed severe (for us it's like if we touch the code that uses google cloud storage, we then likely need a workaround for a new problem).

UPD: sorry for double commenting, github was lagging yesterday

Hi everyone,
Appreciate your patience here. This is rather a big change. Unfortunately, we're not taking any significant feature requests for google-api-ruby-client and hence we won't be able to make this change. We'll circle back if anything pressing comes up.
I'll go ahead and close this PR. Thank you!

@bajajneha27 I'm not sure if you are aware, but httpclient is straight out broken today because it has an old list of CA certificates from 2015 hardcoded in its source: nahi/httpclient#445

I don't understand how this can be considered, "not pressing".

[NivedhaSenthil]

While we work on moving away from HttpClient, a new version of gem that patches the client to use systems default root CA path is now released.

[casperisfine]

Now, httpclient is broken on Ruby 3.4 because it uses mutex_m that has been removed from the stdlib, so the gem would need to update its gemspec.

[dazuma]

We'll make sure mutex_m is included in the google-apis-core gemspec if needed.
