When passing `--auto` flag, only schedule an auto-merge if
the `mergeStateStatus` field is "BLOCKED".
This ensures that a PR will always be merged when passing `--auto` even
if it doesn't have required checks or if checks have already passed.
This avoids loading authorship information for git commits, since it
relies on a GraphQL API that wasn't available before GHE v3.0. The
authorship information wasn't necessary for the merge operation anyway;
just loading the last commit OID was.
When using GITHUB_TOKEN in Actions, the permissions on a repository are
null and therefore we can't check whether the viewer has push access or
not. The solution is to unconditionally check for draft releases instead
of trying to be smart about it. Draft releases are going to be on top,
so we don't have to paginate through all releases in a repository.
"null" was previously rendered in "bright black", an ANSI color that is
not guaranteed to be visible at all depending on the terminal. Switch
the color to cyan to ensure that "null" is visible.
This completely rewrites the PR lookup mechanism so that the caller
must specify the GraphQL fields to query for each PR. Additionally, this
fixes some export problems with `pr view --json`.
Features:
- Each pr command now gets assigned a concept of a Finder. This makes it
easier to stub the PR in tests without having to stub the underlying
HTTP calls or git invocations.
- `pr view --web` is much faster since it only fetches the "url" field.
- `pr diff 123` now skips a whole API call where a whole PR was
unnecessarily preloaded just to access its diff in a subsequent call.
- PullRequestGraphQL query builder is now used to construct queries.
- A bunch of individual commands are now freed of having to know about
concepts such as BaseRepo, Branch, Config, or Remotes.
