From b9a2318becfc9d6ffb92e602adf433faa8cec383 Mon Sep 17 00:00:00 2001 From: Dave Reisner Date: Sat, 14 May 2011 12:54:03 -0400 Subject: trans.c: create transaction prior to checking DB version The addition of the DB version check introduces a lag time between the lockfile creation and the transaction initialization. In cases where the local DB is large enough and/or the user's disk is slow enough, this time is significant enough that its possible for a user to send a SIGINT and leave behind a db.lck file.
