From dc0a13f6813f35bae5fd2de6af4d5524a20d5b82 Mon Sep 17 00:00:00 2001 From: Jonathan Tan Date: Thu, 12 Jul 2018 17:03:06 -0700 Subject: revision: tolerate promised targets of tags In handle_commit(), it is fatal for an annotated tag to point to a non-existent object. --exclude-promisor-objects should relax this rule and allow non-existent objects that are promisor objects, but this is not the case. Update handle_commit() to tolerate this situation. This was observed when cloning from a repository with an annotated tag pointing to a blob. The test included in this patch demonstrates this case.
