www/tt-rss: Simplify ttrssd rc script

[dereks_lifeofadishwasher.com]

Summary

ttrssd rc script has a check if a local database is ready such that at
startup ttrssd will wait 10 seconds for a database connection.

With daemon you can restart the child process with a delay such that the
rc script can be simplified to use command and command_args.

Test Plan

1. service ttrssd status/stop/start while:
2. not running
3. running

2. tail logs waiting for the database to start.
3. See it fail until the database up

not running
status: not running

1. service ttrssd status

		ttrssd is not running.

stop: not running

1. service ttrssd stop

		ttrssd not running? (check /var/run/ttrssd.pid).

start: start

1. service ttrssd start

		Starting ttrssd.

running:
status: displays correct pid

1. service ttrssd status

		ttrssd is running as pid 53703.
		# pgrep -fal daemon
		53703 daemon: sh[53731]
		53731 /usr/local/bin/php /usr/local/www/tt-rss/update_daemon2.php

stop: stops daemon and php process waiting for all childern to finish

1. service ttrssd stop

		Stopping ttrssd.
		Waiting for PIDS: 53703.
		# pgrep -fal daemon
		#

start: displays ttrssd is already running

1. service ttrssd start

		ttrssd already running?  (pid=54520).

2. tailing logs during a failing startup

tail -F /var/log/ttrssd.log
<pre>Exception while creating PDO object:SQLSTATE[08006] [7] connection to server at ".... failed: Connection refused

		Is the server running on that host and accepting TCP/IP connections?... : Connection refused

One issue noticed with daemon is it can't be killed by normal means (service ttrssd stop) if the child process isn't running. I believe this is the cause of the issue? https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=277959 If the rc script needs to handle this I beleive I can add a prestop checking if pgrep -P <parent> return value and killing the parent and deleting the pid file.

Add UPDATING and stop if daemon doesn't have a child

Recommendations from https://lists.freebsd.org/archives/freebsd-ports/2024-June/006287.html

• Add UPDATING because of rc var removal ttrssd_local_db
• Add a stop to INT or TERM the parent daemon.
  • If the child doesn't exist send INT to daemon.
  • If the child exists TERM will propagate to the child.
  • Testing has shown the parentless child will go away.
