#59729: mariadb-10.2 @10.2.29: downloads head of 10.2 branch instead of desired tag
------------------------+--------------------------
 Reporter:  ryandesign  |      Owner:  michaelld
     Type:  defect      |     Status:  assigned
 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.6.2
 Keywords:              |       Port:  mariadb-10.2
------------------------+--------------------------
 The mariadb-10.2 port has had multiple stealth updates recently, and the
 reason appears to be that the port is downloading from the head of the
 10.2 branch, rather than the intended fixed tag.

 This happens because the port sets `git.branch ${version_branch}`. It
 probably shouldn't do that. `git.branch` is the variable that controls
 which commit/branch/tag will be downloaded. By default it is set to the
 third parameter of the `github.setup` call.
