#commit_count(ref, options = {}) ⇒ Integer

Count commits in the repository.

Examples:

Count commits in a single branch

commit_count('master')

Count commits across multiple branches using revisions

commit_count(nil, revisions: ['feature-a', 'feature-b'])

Count commits in all branches using revisions

commit_count(nil, revisions: ['--all'])

Count commits in branch-2 but not in branch-1

commit_count(nil, revisions: ['branch-2', '--not', 'branch-1'])

Parameters:

  • ref (String) —

    The revision to count commits from (soft deprecated, use revisions instead)

  • options (Hash) (defaults to: {}) —

    Options for counting commits

Options Hash (options):

  • :revisions (Array<String>) —

    Multiple revisions to count commits from. Supports pseudo-revisions like –all, –branches, –tags, –not, –glob. Takes precedence over :all and ref parameters.

  • :all (Boolean) —

    Count commits from all refs (soft deprecated, use revisions: [‘–all’])

  • :first_parent (Boolean) —

    Only follow first parent on merge commits

  • :after (Time) —

    Only count commits after this time

  • :before (Time) —

    Only count commits before this time

  • :path (String) —

    Only count commits that touch this path

  • :max_count (Integer) —

    Maximum number of commits to count

Returns:

  • (Integer) —

    The number of commits

#find_changed_paths(objects, merge_commit_diff_mode: nil, find_renames: false, diff_filters: nil) ⇒ Object

When finding changed paths and passing a sha for a merge commit we can specify how to diff the commit.

When diffing a merge commit and merge_commit_diff_mode is :all_parents file paths are only returned if changed in both parents (or all parents if diffing an octopus merge)

This means if we create a merge request that includes a merge commit of changes already existing in the target branch, we can omit those changes when looking up the changed paths.

e.g.

1. User branches from master to new branch named feature/foo_bar
2. User changes ./foo_bar.rb and commits change to feature/foo_bar
3. Another user merges a change to ./bar_baz.rb to master
4. User merges master into feature/foo_bar
5. User pushes to GitLab
6. GitLab checks which files have changed

case merge_commit_diff_mode when :all_parents

['foo_bar.rb']

when :include_merges

['foo_bar.rb', 'bar_baz.rb'],

else # defaults to :include_merges behavior

['foo_bar.rb', 'bar_baz.rb'],
