Subject: [PATCH] Use gdbm_errno with gdbm_open
Date: Sat, 25 Mar 2017 07:55:54 +0100 [thread overview]

Hello,
there was one report about gdbm_open() failing. The patch uses gdbm_errno / gdbm_strerror() to know what exactly happened. I've checked that it works:
ztie: error opening database file /Users/sgniazdowski/db3 (Can't be writer)
– after ztie to already opened database. I hope Airmail will not mess up the patch. It is also attached.
