GitHub GraphQL repo commit history query

query.graphql

{
  repository(name: "sickvim", owner: "jonathansick") {
    ref(qualifiedName: "master") {
      target {
        ... on Commit {
          id
          history(first: 5) {
            pageInfo {
              hasNextPage
            }
            edges {
              node {
                messageHeadline
                oid
                message
                author {
                  name
                  email
                  date
                }
              }
            }
          }
        }
      }
    }
  }
}

can we use graphQL to get details about a given commit hash, (just like in commit REST API)

Can we use the above code to get the details of first 2 commits before a certain commit ( hash 7e6c355e1c250036c9ba0d76133b5068b2444f3d ) that exists in the repository. Here is my code.

query { 
repository(owner:"wso2",name:"product-is"){
  object(expression:"master"){
    ... on Commit {
      history(first:2,before:"7e6c355e1c250036c9ba0d76133b5068b2444f3d"){
        edges{
          node{
            id
            blame(path:"pom.xml"){
              ranges{
                startingLine
                endingLine
                commit{
                  author {
                  
                    email
                    name
                  }
                }
              }
            }
            
          }
        }
        
        
      }
    }
  }
}
    
  

}
 

but it gives me this error

"errors": [
    {
      "message": "backwards pagination unsupported for CommitHistoryConnection",
      "type": "INVALID_CURSOR_ARGUMENTS",
      "locations": [
        {
          "line": 11,
          "column": 9
        }
      ],
      "path": [
        "repository",
        "object",
        "history",
        "edges"
      ]
    }
  ]

What I am doing wrong

@jonathansick This query works great for me, I'm just not sure why. Based on SQL type experience, what I want to do is a "join" between Repo and Commit fields and I don't understand how that maps onto graphQL's fragments or why the ref -> target is necessary. Any clarification would be mightily appreciated.

@kasunsiyambalapitiya before needs to be a cursor. Generally, I think, first is used with after and last is used with before.

This was the first Google result my search, can you update the code to use defaultBranchRef instead of ref(…)?

If you do, please at least comment with the original version (or maybe make another file in the gist?) because this query is also useful to figure out how to get history from a certain point (be that tag or commit oid).

I let this here maybe it helps somebody else to get commits for defaultBranchRef:

  {
    repository(owner: "sulu", name: "sulu") {
      defaultBranchRef {
        name
        target {
          ... on Commit {
            history {
              totalCount
            }
          }
        }
      }
      stargazers {
        totalCount
      }
      releases {
        totalCount
      }
    }
  }
