From: Johannes Schindelin Date: Mon, 01 Aug 2016 11:44:23 GMT Subject: [PATCH v6 08/16] merge-recursive: allow write_tree_from_memory() to error out Message-ID: In-Reply-To: It is possible that a tree cannot be written (think: disk full). We will want to give the caller a chance to clean up instead of letting the program die() in such a case.
