From 2d8ef5e24fd3d38ffc2379ca32eaeef8c9eee1a7 Mon Sep 17 00:00:00 2001 From: Michael Paquier Date: Mon, 22 Jul 2024 09:28:01 +0900 Subject: [PATCH] Add new error code for "file name too long" This new error code, named file_name_too_long, maps internally to the errno ENAMETOOLONG to produce a proper error code rather than an internal code under errcode_for_file_access(). This error code can be reached with some SQL command patterns, like a snapshot file name.
