I modified my mqttwarn scripts today to ignore some messages.
When restarting it, it wouldn’t. No output whatsoever.
[20:07 mqtt01 dvl ~] % sudo service mqttwarn restart mqttwarn not running? (check /var/run/mqttwarn/mqttwarn.pid). Starting mqttwarn. [20:07 mqtt01 dvl ~] % sudo ps auwwx | grep warn dvl 4191 0.0 0.0 13836 2408 1 S+J 20:07 0:00.00 grep warn
Eventually, I tried running it by hand:
[20:08 mqtt01 dvl ~] % sudo /usr/local/bin/mqttwarn Traceback (most recent call last): File "/usr/local/bin/mqttwarn", line 8, insys.exit(run()) ^^^^^ File "/usr/local/lib/python3.11/site-packages/mqttwarn/commands.py", line 93, in run run_mqttwarn(configfile=options["--config-file"]) File "/usr/local/lib/python3.11/site-packages/mqttwarn/commands.py", line 140, in run_mqttwarn config = load_configuration(configfile=configfile, name=scriptname) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/site-packages/mqttwarn/configuration.py", line 262, in load_configuration raise FileNotFoundError('Configuration file "{}" does not exist'.format(configfile)) FileNotFoundError: Configuration file "mqttwarn.ini" does not exist
Where is that mqttwarn.ini?
[20:08 mqtt01 dvl ~] % locate mqttwarn.ini /usr/local/etc/mqttwarn/mqttwarn.ini /usr/local/etc/py311-mqttwarn/mqttwarn.ini /usr/local/etc/py311-mqttwarn/mqttwarn.ini.sample /usr/local/lib/python3.11/site-packages/mqttwarn/examples/basic/mqttwarn.ini
What’s this /usr/local/etc/py311-mqttwarn directory? That’s not right. It should not have that prefix.
[20:08 mqtt01 dvl ~] % pkg which /usr/local/etc/py311-mqttwarn/mqttwarn.ini.sample /usr/local/etc/py311-mqttwarn/mqttwarn.ini.sample was installed by package py311-mqttwarn-0.35.0_1
Installed by the package. That’s not right. I don’t know why this is the way it is:
[20:41 mydev dvl /usr/ports/sysutils/py-mqttwarn] % make -V ETCDIR /usr/local/etc/py311-mqttwarn
There’s nothing in here:
[20:41 mydev dvl /usr/ports/sysutils/py-mqttwarn] % grep -r ETCDIR *

Back to getting it started
Next, I added the configuration file via full path:
[20:09 mqtt01 dvl ~] % sudo /usr/local/bin/mqttwarn --config-file=/usr/local/etc/mqttwarn/mqttwarn.ini Traceback (most recent call last): File "/usr/local/bin/mqttwarn", line 8, insys.exit(run()) ^^^^^ File "/usr/local/lib/python3.11/site-packages/mqttwarn/commands.py", line 93, in run run_mqttwarn(configfile=options["--config-file"]) File "/usr/local/lib/python3.11/site-packages/mqttwarn/commands.py", line 140, in run_mqttwarn config = load_configuration(configfile=configfile, name=scriptname) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/site-packages/mqttwarn/configuration.py", line 273, in load_configuration return Config(configfile, defaults=defaults) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/site-packages/mqttwarn/configuration.py", line 175, in __init__ self.functions = load_functions(functions_file) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/site-packages/mqttwarn/util.py", line 227, in load_functions py_mod = load_module_from_file(filepath) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/site-packages/mqttwarn/util.py", line 156, in load_module_from_file loader.exec_module(mod) File " ", line 936, in exec_module File " ", line 1074, in get_code File " ", line 1004, in source_to_code File " ", line 241, in _call_with_frames_removed File "/usr/local/etc/mqttwarn/my-functions.py", line 26 if data['user'] == 'dvl':: ^ SyntaxError: invalid syntax
OK, I fixed my syntax error, and tried again:

There, it’s running.
Fixing the rc.d start
To fix the start via service, I added a symlink.
[20:21 mqtt01 dvl /usr/local/etc/py311-mqttwarn] % ls -l total 9 -rw-r----- 1 mqttwarn mqttwarn 3831 2024.06.29 15:51 mqttwarn.ini -rw-r----- 1 mqttwarn mqttwarn 3831 2024.06.29 15:51 mqttwarn.ini.sample [20:21 mqtt01 dvl /usr/local/etc/py311-mqttwarn] % sudo rm mqttwarn.ini [20:21 mqtt01 dvl /usr/local/etc/py311-mqttwarn] % sudo ln -s ../mqttwarn/mqttwarn.ini .
The restart worked, ignore the check PID warning, that’s because I started it from the command line.

What I still don’t know: why is ETCDIR borked?
