+	Parents []Commit `json:"parents,omitempty"`


Based on #180 and #520 (comment) (/cc @gmlewis), I think we'd want to go with []*Commit here. Even though it's a little inconsistent with other similar structs.
At least that's what I think @gmlewis would request.

Got it, will fix.

gmlewis · 2017-03-29T17:05:01Z

As part of this cleanup, can you please add HTMLURL to type Commit struct in git_commits.go (I cam across this while looking at the parents response)?

Also, in search.go can you please rename Total in type CommitsSearchResult struct to TotalCount for consistency?

Since these are breaking API changes, we also need to bump the version number.

Thank you!

amirilovic · 2017-03-29T19:45:18Z

@gmlewis All fine for TotalCount.

For HTMLURL in Commit, I think it's fine right now.
If you take a look at https://developer.github.com/v3/search/#search-commits results are represented as CommitResult which does have HTMLURL

type CommitResult struct {
...
Commit *Commit `json:"commit,omitempty"`
HTMLURL *string `json:"html_url,omitempty"`
....
}

Also for RepositoryCommit as a result of https://developer.github.com/v3/repos/commits/#get-a-single-commit

type RepositoryCommit struct {
...
Commit *Commit `json:"commit,omitempty"`
HTMLURL *string `json:"html_url,omitempty"`
...
}

So, as I understand both result structures are wrappers around a commit with a specific HTMLURL, this is inline with github docs.

Also parents in get single commit don't have html_url

...
"parents": [
{
"url": "https://api.github.com/repos/octocat/Hello-World/commits/6dcb09b5b57875f334f61aebed695e2e4193db5e",
"sha": "6dcb09b5b57875f334f61aebed695e2e4193db5e"
}
],
...

As far as I see in docs for other endpoints parents array is always just a reference to parent commits it never contains actual commit data, so maybe the best thing would be to create new struct to that represents that like:

type CommitReference {
SHA *string `json:"sha,omitempty"`
URL *string `json:"url,omitempty"`
HTMLURL *string `json:"html_url,omitempty"`
}

and change RepositoryResult and CommitResult to be:

type RepositoryCommit struct {
...
Parents []CommitReference `json:"parents,omitempty"`
...
}
type CommitResult struct {
...
Parents []CommitReference `json:"parents,omitempty"`
...
}

What do you think?

Also, in search.go can you please rename Total in type CommitsSearchResult struct to TotalCount for consistency?

@gmlewis, I don't think we should do this. At least not in this PR. It makes things inconsistent. Look at the rest of search.go:

// RepositoriesSearchResult represents the result of a repositories search.typeRepositoriesSearchResultstruct {
Total*int`json:"total_count,omitempty"`IncompleteResults*bool`json:"incomplete_results,omitempty"`Repositories []Repository`json:"items,omitempty"`
}
// IssuesSearchResult represents the result of an issues search.typeIssuesSearchResultstruct {
Total*int`json:"total_count,omitempty"`IncompleteResults*bool`json:"incomplete_results,omitempty"`Issues []Issue`json:"items,omitempty"`
}
// UsersSearchResult represents the result of a users search.typeUsersSearchResultstruct {
Total*int`json:"total_count,omitempty"`IncompleteResults*bool`json:"incomplete_results,omitempty"`Users []User`json:"items,omitempty"`
}
// CodeSearchResult represents the result of a code search.typeCodeSearchResultstruct {
Total*int`json:"total_count,omitempty"`IncompleteResults*bool`json:"incomplete_results,omitempty"`CodeResults []CodeResult`json:"items,omitempty"`
}

Do you see how it'd be inconsistent to change Total to TotalCount only in CommitsSearchResult?

// CommitsSearchResult represents the result of a commits search.typeCommitsSearchResultstruct {
TotalCount*int`json:"total_count,omitempty"`IncompleteResults*bool`json:"incomplete_results,omitempty"`Commits []*CommitResult`json:"items,omitempty"`
}

We've already discussed this at #520 (comment) previously, and you agreed to prefer consistency there.

@gmlewis Can you open an issue about this instead, so we can come to a decision and address all similar structs at once? But let's keep it out of scope of this PR.

@amirilovic Please revert TotalCount to Total for now.

gmlewis · 2017-03-29T23:28:31Z

OK, SGTM.
Opened: #605
Sorry for the trouble, @amirilovic.

dmitshur · 2017-03-29T23:41:42Z

About HTMLURL in Commit, I agree with @gmlewis that we should add it there.

@amirilovic, it's pretty subtle as to why.

If you look at our https://godoc.org/github.com/google/go-github/github#GitService.GetCommit method, it returns Commit. It maps to https://developer.github.com/v3/git/commits/#get-a-commit GitHub API endpoint, and its example output does not contain a "html_url" field:

{
"sha": "7638417db6d59f3c431d3e1f261cc637155684cd",
"url": "https://api.github.com/repos/octocat/Hello-World/git/commits/7638417db6d59f3c431d3e1f261cc637155684cd",
"author": {
"date": "2014-11-07T22:01:45Z",
"name": "Scott Chacon",
"email": "schacon@gmail.com"
},
"committer": {
"date": "2014-11-07T22:01:45Z",
"name": "Scott Chacon",
"email": "schacon@gmail.com"
},
"message": "added readme, because im a good github citizen",
"tree": {
"url": "https://api.github.com/repos/octocat/Hello-World/git/trees/691272480426f78a0138979dd3ce63b77f706feb",
"sha": "691272480426f78a0138979dd3ce63b77f706feb"
},
"parents": [
{
"url": "https://api.github.com/repos/octocat/Hello-World/git/commits/1acc419d4d6a9ce985db7be48c6349a0475975b5",
"sha": "1acc419d4d6a9ce985db7be48c6349a0475975b5"
}
]
}

However, GitHub API documentation is not always 100% up to date and does not always show all fields that the real API returns. This is an example of that.

If you hit that endpoint for real, it includes "html_url" field. For example, try:

https://api.github.com/repos/octocat/Hello-World/git/commits/7fd1a60b01f91b314f59955a4e4d4e80d8edf11d

"html_url": "https://github.com/octocat/Hello-World/commit/7fd1a60b01f91b314f59955a4e4d4e80d8edf11d",

},
"message": "Merge pull request #6 from Spaceghost/patch-1\n\nNew line at end of file.",
"parents": [
{
"sha": "553c2077f0edc3d5dc5d17262f6aa498e69d6f8e",
"url": "https://api.github.com/repos/octocat/Hello-World/git/commits/553c2077f0edc3d5dc5d17262f6aa498e69d6f8e",
"html_url": "https://github.com/octocat/Hello-World/commit/553c2077f0edc3d5dc5d17262f6aa498e69d6f8e"
},
{
"sha": "762941318ee16e59dabbacb1b4049eec22f0d303",
"url": "https://api.github.com/repos/octocat/Hello-World/git/commits/762941318ee16e59dabbacb1b4049eec22f0d303",
"html_url": "https://github.com/octocat/Hello-World/commit/762941318ee16e59dabbacb1b4049eec22f0d303"
}
]
}

Also note that parents have "html_url" field too.

So, Commit should have HTMLURL.

They've probably added it more recently, and didn't update their old documentation examples.

amirilovic · 2017-03-30T03:26:55Z

@shurcooL Good point.

dmitshur · 2017-03-30T04:42:16Z

 // Commit represents a GitHub commit.
 type Commit struct {
 	SHA *string `json:"sha,omitempty"`
+	HTMLURL *string `json:"html_url,omitempty"`


Move it near URL, that should be a more fitting place for it.
See
go-github/github/repos_commits.go
Line 24 in 3c8f26c
HTMLURL*string`json:"html_url,omitempty"`
.

amirilovic · 2017-03-30T19:54:55Z

@shurcooL Anything else that needs to be done here?

dmitshur

My only request is to add a blank line – see inline comment for details.

Aside from that, I don't see any issues, so this will have my LGTM after this one change request. Thanks!

dmitshur · 2017-03-30T20:05:52Z

+	URL *string `json:"url,omitempty"`
+	CommentsURL *string `json:"comments_url,omitempty"`
+	Repository *Repository `json:"repository,omitempty"`
+	Score *float64 `json:"score,omitempty"`


As an observation, CommitResult now looks very similar to RepositoryCommit. But it differs in the last 2 fields. RepositoryCommit has Stats and Files, which CommitResult does not, and CommitResult has Repository and Score, that RepositoryCommit doesn't.
That's completely fine, just pointing it out.
However, I think it'd be nice to add a blank line between CommentsURL field and Repository field, to separate the common vs differing fields, similar to the blank line separator that RepositoryCommit already has.
