From db82b8d7eb646a2d31f1b4e52ab4a623743192e9 Mon Sep 17 00:00:00 2001 From: Jens Baumgart Date: Mon, 26 Jul 2010 10:18:47 +0200 Subject: [PATCH] Fix concurrent read / write issue in LockFile on Windows LockFile.commit fails if another thread concurrently reads the base file. The problem is fixed by retrying the rename operation if it fails.
