From: Johannes Schindelin Date: Fri, 22 Jul 2016 12:25:28 GMT Subject: [PATCH v4 08/16] merge-recursive: allow write_tree_from_memory() to error out Message-ID: <2d80e8c9fce38821fa95646951f7d8351fec7db8.1469187653.git.johannes.schindelin@gmx.de> 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.
