Can you give a sample query to reproduce the problem you’re seeing? This would make it much simpler to ensure that I’m seeing the same thing you are.

Explorer query:

{
  repository(name: "rails", owner: "rails") {
    name,
    owner {
      login
    },
    ref(qualifiedName: "master") {
      name,
      target {
        ... on Commit {
          history(first: 3) {
            edges {
              node {
                messageHeadline
                oid
                abbreviatedOid
                committedDate
              }
            }
          }
        }
      }
    }
  }
}

GraphQL returns (abrev):

"node": {
  "messageHeadline": "Re-organize `init_internals`",
  "oid": "2c0729d8cb13100ea576337ebb7703320203c548",
  "abbreviatedOid": "2c0729d",
  "committedDate": "2019-04-23T20:14:25Z"

git log command (on a local clone):

git log -n1 --format="%h %ci"

Git command returns:

2c0729d8cb 2019-04-24 05:14:25 +0900

Note the difference between abbreviatedOid (7 characters) and the git log %h string (10 characters)…

Thanks for taking the time to review the example.  GraphQL vs v3 is messy, as I kind of view GraphQL as SQL with no (or a very limited) ‘where’ clause.

My question is related to the code I’m using to update a Ruby doc site on GitHub.io:

https://msp-greg.github.io/

Several of the repos are using abreviated SHA’s of 8 characters, with Ruby & Rails having 10.

With the current setup, I’m using v3 and git commands, but I need to test/benchmark using GraphQL and possibly hitting Rubygems.org for some of the info…

Abbreviated hashes, no matter what length is used, are not future-proof, because as a repository grows collisions will become more likely using anything less than the full hash. You should only use the abbreviated hash for the text of a link and use the full hash in the URL.

You can also abbreviate the full hash yourself to whatever arbitrary length you choose.

I hope that helps!
