From 579b78e22feab7fe7cc627355cbb270cd91aebb4 Mon Sep 17 00:00:00 2001 From: Selva Nair Date: Wed, 27 Jul 2022 23:45:07 -0400 Subject: [PATCH] Do not skip ERROR:/SUCCESS: response from management interface Generally we expect a response of SUCCESS: or ERROR: to every command sent to the management interface. But, while in the management-hold state, sending "signal foo" returns only the following reply (with foo = SIGHUP, SIGUSR1 etc.): >HOLD:Waiting for hold release:0 Fix by always responding ERROR: signal 'foo' is currently ignored" followed by the above line. Though this is seldom seen in practice[*], such violation of the protocol could stall clients like the GUI. So fix it. [*] One way this happens is with SIGHUP sent before the daemon is on hold state which it enters before the SIGHUP is received.
