CACHED_METHODS =

Methods that cache data from the Git repository.

Each entry in this Array should have a corresponding method with the exact same name. The cache key used by those methods must also match method's name.

For example, for entry `:commit_count` there's a method called `commit_count` which stores its data in the `commit_count` cache key.

Certain method caches should be refreshed when certain types of files are changed. This Hash maps file types (as returned by Gitlab::FileDetector) to the corresponding methods to call for refreshing caches.

#has_ambiguous_refs? ⇒ Boolean

It's possible for a tag name to be a prefix (including slash) of a branch name, or vice versa. For instance, a tag named `foo` means we can't create a tag `foo/bar`, but we can create a branch `foo/bar`.

If we know a repository has no refs of this type (which is the common case) then separating refs from paths - as in ExtractsRef - can be faster.

This method only checks one level deep, so only prefixes that contain no slashes are considered. If a repository has a tag `foo/bar` and a branch `foo/bar/baz`, it will return false.

Returns:

  • (Boolean)
