From c1703d7634a61b4d08d77fa0d9ca7e7ad92c3cb8 Mon Sep 17 00:00:00 2001 From: Ronnie Sahlberg Date: Fri, 20 Jun 2014 07:42:57 -0700 Subject: [PATCH] refs.c: make update_ref_write update a strbuf on failure Change update_ref_write to also update an error strbuf on failure. This makes the error available to ref_transaction_commit callers if the transaction failed due to update_ref_sha1/write_ref_sha1 failures.
