From f5185881f7b01f67b5b64218804749b733f08d44 Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Mon, 21 Nov 2016 22:14:33 +0200 Subject: cli: consider files vanishing during notmuch new non-fatal If some software other than notmuch new renames or removes files during the notmuch new scan (specifically after scandir but before indexing the file), keep going instead of bailing out. Failing to index the file is just a race condition between notmuch and the other software; the rename could happen after the notmuch new scan anyway. It's not fatal, and we'll catch the renamed files on the next scan. Add a new exit code for when files vanished, so the caller has a chance to detect the race and re-run notmuch new to recover.
