Node: Role of CTC in semver-major changes needs clarification

[Trott]

In light of https://github.com/nodejs/node/pull/7846:

The onboarding doc indicates that all semver major changes must be reviewed by CTC "in some form". I think this could use some review and clarification:

• It's not clear what "in some form" entails.
• As far as I know, the onboarding doc is the only place this requirement appears. If it's not misinformation, then it should be documented elsewhere. (Maybe it is and I just haven't noticed it?)
• We don't appear to be sticking to this, except in the loosest conceivable interpretation of "in some form". See #7168.

I think the CTC should decide:

• Does the CTC need to review all semver-major changes?
• If so, then can we get some kind of specifics about what that means?
• If not, then we should remove that bit of information from the onboarding doc.

It's not clear to me that more CTC oversight would have prevented the issue that has come up with that change. I'm not advocating for anything here, other than clarifying the process. I'm fine with more formal CTC oversight on semver-major issues and I'm fine with eliminating the requirement. I just want clarity and consistent application of whatever rules are decided upon.

In my opinion, CTC should formally review breaking changes, unless that is a V8 update.

[jasnell]

Yes, CTC members should review and sign off on all semver-major changes.
There should be at least one lgtm from a CTC member.

That happened, didn't it? Trevor signed off on both #2498 and #7168.

An ok baseline but really we want the CTC as a group to have their eyes on these not just individuals. I don't see a huge problem with the current wording _in that document_.

The actual problem here is our dev policy docs never actually got merged into this repo during the io.js merge, so the official policy is under here:

Pull Requests that require an increase in the Major version must be elevated for review by the TSC. This does not necessarily mean that the PR must be put onto the TSC meeting agenda. If enough TSC members sign-off on the PR and there is clear consensus among TSC members for the change, the Pull Request can be landed. Where there is disagreement among TSC members, semver-major Pull Requests should be put on the TSC meeting agenda.

_Note: this language is outdated and was written before the TSC/CTC split, but you get the idea._

@misterdjules citgm was run on https://github.com/nodejs/node/pull/7168, but after it was run more changes were made. It likely should have been run again before it landed.

In general I think passing citgm should be a minimum bar for any semver major change

[misterdjules]

@misterdjules citgm was run on #7168, but after it was run more changes were made. It likely should have been run again before it landed.

@TheAlphaNerd My apologies for the confusion, my artisanal search method failed to catch that. Thank you for pointing this out!

[Trott]

I think incorporating a modified version of the text @Fishrock123 quotes would be a good move. How's this?:

Pull Requests that require an increase in the Major version must be elevated for review by the CTC. This does not necessarily mean that the PR must be put onto the CTC meeting agenda. If multiple CTC members approve (LGTM) the PR and no Collaborators oppose the PR, it can be landed. Where there is disagreement among CTC members or objections from one or more Collaborators, semver-major Pull Requests should be put on the CTC meeting agenda.

@jasnell suggested that at least one CTC member should LGTM the PR. This wording requires at least two CTC members. Otherwise, I _think_ this is consistent with all the other comments.

Also: Yeah, I'm not necessarily saying _anything_ went wrong with the way that PR landed. I'm saying that things are currently vague. I'm usually a fan of not getting too specific if it's not necessary, but in this case, I think it is warranted.

[jasnell]

I'm good with this, albeit for some of the more specialized parts of core, two lgtms may be more difficult to come by.

[Trott]

I've opened https://github.com/nodejs/node/pull/7955 to document this change. Hopefully we can get enough CTC members to LGTM that to land it. In the meantime, I'll remove the ctc-agenda label from this issue and take it off the meeting agenda as discussion can happen in that PR. We can always put it back on the agenda for next week if it turns out there's no consensus.
