Package: supervisor
Version: 4.2.5-1
Followup-For: Bug #877086
X-Debbugs-Cc: denis.roussel@gmail.com

Dear Maintainer,

   * What led up to the situation?

Attempting to restart the Supervisor service using the SysV init script (/etc/init.d/supervisor restart) on Debian Bookworm, as part of routine maintenance (eg : Docker context).

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

Executed /etc/init.d/supervisor restart, which stopped the daemon but failed to restart it due to missing start invocation in the restart() function.

   * What was the outcome of this action?

Supervisor daemon stopped (no process via ps aux | grep supervisord), leaving managed processes down until manual start.

   * What outcome did you expect instead?

Daemon to stop gracefully and then restart automatically, restoring all managed processes.


The restart() function in debian/supervisor.init only stops the service via start-stop-daemon --stop but lacks a subsequent start call, leaving it stopped. This is a known longstanding issue (bug #877086).
Attached is a DEP-3 formatted patch (v5) that:

Changes the echo message to "Stopping $DESC: " for clarity.
Inserts $0 start after the post-stop echo, with exact tab indentation matching the original.

Tested on Debian Bookworm: After applying and rebuilding/installing the .deb, restart now stops, echoes "supervisor.", then calls start() successfully.
Please apply this patch and close #877086.

Thanks.
