Undefined function git_branch_name()

[sphuber]

When I use git_branch_name() I get Call to undefined function git_branch_name() however looking at the code it does seem to be implemented. Am I missing something?

Found the source of the issue none of the zend_entry_function stubs were defined in php_git2.c. Also the implementation of git_branch_upstream was missing from branch.c
