From 59f9d2dd60f97c55c92c3273903f64048a27e513 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Sun, 14 Jan 2018 17:18:19 +0700 Subject: [PATCH] read-cache.c: move tempfile creation/cleanup out of write_shared_index MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit For one thing, we have more consistent cleanup procedure now and always keep errno intact. The real purpose is the ability to break out of write_locked_index() early when mks_tempfile() fails in the next patch. It's more awkward to do it if this mks_tempfile() is still inside write_shared_index().
