After uninstalling the version. 2.1.4 and installing 2.2.0 does not work the script

[juanamm]

Describe the bug
With version 2.1.4 everything works correctly, but I uninstalled it and installed v. 2.2 to have my system updated.
When restarting liquidsoap with the command: sudo systemctl restart main-liquidsoap
gives error at "admin_icecast=getenv("ADMIN_ICECAST")".
The environment variables issue was already fixed in the previous version, since I use Liquidsoap as a daemon, I edited the service file and added the path to the environment variables.
sudo vim /etc/systemd/system/main-liquidsoap.service

[service]
EnvironmentFile=/etc/environment

sudo systemctl daemon-reload
ERROR: Aug 27 05:43:39 ip-172-31-13-127 liquidsoap[45816]: admin_icecast=getenv("ADMIN_ICECAST")
Aug 27 05:43:39 ip-172-31-13-127 liquidsoap[45816]: Error 15: Missing arguments in function application: string.

To rule out that the error was that the environment variables were not read correctly, I edited the script and put the values ​​in plain text.
Example:
admin_icecast="juan"
...
Result: Parse Error

Hi @juanamm,
You need to update your script to migrate from liquidsoap 2.1.4 to 2.2.0, and you can find the migration guide on the liquidsoap site.

If I were you, I'd change the script to something like this

1. Settings

   # Settings
   #settings.server.telnet := true
   #settings.server.telnet.port := 8595
   settings.log.level := 3
   
   settings.harbor.bind_addrs := ["0.0.0.0"]
   
   # Metadata
   settings.tag.encodings := ["UTF-8", "ISO-8859-1"]
   settings.encoder.metadata.export := ["artist", "title"])
   settings.decoder.file_extensions.taglib := ["mp3", "ogg", "mkv", "wav", "flac", "mp4", "m4a"]

   These settings require further migration

   # settings.harbor.ssl.certificate.set("/etc/letsencrypt/live/osirisfm.org/fullchain.pem")
   # settings.harbor.ssl.private_key.set("/etc/letsencrypt/live/osirisfm.org/privkey.pem")

2. Environment

   # Environment Variables
   admin_icecast=environment.get("ADMIN_ICECAST")
   password_admin=environment.get("PASSWORD_ADMIN")
   password_dj=environment.get("PASSWORD_DJ")
   password_inv1=environment.get("PASSWORD_INV1")
   password_inv2=environment.get("PASSWORD_INV2")
   password_inv3=environment.get("PASSWORD_INV3")
   source_passw=environment.get("SOURCE_PASSW")
   host_https=environment.get("HOST_HTTPS")
   port_https=environment.get("PORT_HTTPS")
   port_live=environment.get("PORT_LIVE")
   port_inv1=environment.get("PORT_INV1")
   port_inv2=environment.get("PORT_INV2")
   port_inv3=environment.get("PORT_INV3")
   host_https_no_prot=environment.get("HOST_HTTPS_NO_PROT")
   
   # Convert string to integer
   port_live_int=int_of_string(port_live)
   port_https_int=int_of_string(port_https)
   port_inv1_int=int_of_string(port_inv1)
   port_inv2_int=int_of_string(port_inv2)
   port_inv3_int=int_of_string(port_inv3)

3. Functions
   I do not fully understand why you need them

   # Function to apply metadata to the stream
   def apply_metadata(m) =
       log("calling apply_metadata")
   
       artist=url.encode(m["artist"])
       title=url.encode(m["title"])
   
       if (artist=="" and title=="") then
           log("Artist and title all empty!")
       else
           icy="#{artist}+-+#{title}"
           log("icy for icecast metadata: #{icy}")
   
           # Update mp3 stream metadata
           command=process.quote.command(
               args=["-m", "2", "-u", admin_icecast ^ ":" ^ password_admin,
                     "https://#{host_https}:#{port_https_int}/admin/metadata?mount=%2Fstream.mp3&mode=updinfo&charset=UTF-8&song=#{icy}"], "curl"
           )
           process.run(timeout=4.0, command)
       end
   end
   
   # Run apply_metadata_thread on new metadata
   def apply_metadata_thread(m) =
       thread.run({apply_metadata(m)})
   end

   Especially why do you use curl instead of http.get?

Thanks for your advice @vitoyucepi , now I uninstalled v 2.2.0 because didn't know the reasons for the errors and I went back to 2.1.4.

But I will copy the modifications that you have proposed to try it at some point and I will read the guide that you have shared with me.

EDIT:
In part 3, I got that code snippets from here MAKE A PRIVATE WEB-RADIO WITH LIQUIDSOAP 2.2X

I am using an EC2 t2.micro from aws and it is very difficult to install everything again due to the limited resources of that instance, 1 processor and 1GB of RAM.
But soon I will migrate to a t2.medium to reinstall everything and then return to the t2.micro which is the only one that accepts the free tier in my country.

[juanamm]

@vitoyucepi I have edited my answer because I just remembered where I got that code from part 3 Functions which is not entirely clear to you.
I hope this new data helps somewhat.

[vitoyucepi]

It is not necessary to use the apply_metadata_thread and apply_metadata functions for your setup since they are only used to transfer metadata between servers.

[juanamm]

@vitoyucepi
I have done my best migration attempt, followed your advice and read the official documentation recommended.
I had to configure the part of the certificates by myself because that information was not in your recommendations.
I have not been able to get main-liquidsoap to restart, I will copy all the information as complete as possible for you to help me.

Something wrong with settings.

1. Default values

   # settings.log.level := 3
   # settings.harbor.bind_addrs := ["0.0.0.0"]

2. Do you need these options?

   # settings.encoder.metadata.export := ["artist", "title"]
   # settings.decoder.file_extensions.taglib := ["mp3", "ogg", "mkv", "wav", "flac", "mp4", "m4a"]

3. I think this option no longer exists.

   # settings.tag.encodings := ["UTF-8", "ISO-8859-1"]

@vitoyucepi
Now everything works correctly, thank you very much! 👍

Edit:
The thing that I have noticed different with the use, is that with v.2.1.4, using lame for mp3 main-liquidsoap quickly obeyed the command to restart (using EC2 aws instance t2.micro)
Now with v.2.2.0, using ffmpegand EC2 aws instance t2.medium, it takes a long time for the service to restart, it stays in the state: activating ...

I have changed the codec to libmp3lame
Syntax used:

%ffmpeg(format="mp3",
      %audio(codec="libmp3lame", samplerate=44100, bitrate=192000)
    ),

Now there are 3 questions:

1. Is the above syntax correct?
2. I think that service's restart becomes slow because it has many packages installed, can you help me to leave only the ffmpeg codecs for audio and to remove unnecessary ffmpeg packages for video codecs ?
3. Why does the set warning keep appearing if I have the code supposedly fixed?
   WARNING: "set" is deprecated and will be removed in future version. Please use `settings.path.to.key := value

[vitoyucepi]

1. Try this

   %ffmpeg(%audio(codec="libmp3lame", b="128k"), format="mp3")

   But %mp3 should work because you used command similar to this opam install liquidsoap lame.
2. Restart is not supper fast.
3. There are some settings with set.

1. Probably, these warnings were caused by

   liquidsoap/src/libs/server.liq

   Lines 4 to 7 in cc8f858

   	def server.telnet(~port=1234) =
   	settings.server.telnet.port.set(port)
   	settings.server.telnet.set(true)
   	end

   You can locate the file using find /home/icecast2/ -name 'server.liq' and replace

     settings.server.telnet.port.set(port)
     settings.server.telnet.set(true)

   with

     settings.server.telnet.port := port
     settings.server.telnet := true

2. Can you share all the steps to make this more modern demonization and remove deprecated safely?

[vitoyucepi]

I have some suggestions regarding this systemd config.

1. You can create a service file /etc/systemd/system/[email protected]

   [Unit]
   Description=Liquidsoap daemon for %I
   After=network.target
   Documentation=https://www.liquidsoap.info/
   
   [Service]

   Restart=always
   
   [Install]
   WantedBy=multi-user.target

2. It may be necessary to execute systemctl daemon-reload here.
3. Override service file by invoking systemctl edit [email protected]

   [Service]
   EnvironmentFile=/home/icecast2/liquidsoap/%I.env

4. Place your main script in /home/icecast2/liquidsoap/main.liq.
5. Place the environment file in /home/icecast2/liquidsoap/main.env.
6. Reload service files systemctl daemon-reload.
7. Enable it and start by systemctl enable --now [email protected].

This setup is inspired by arch one.
I think it's superior to your existing config because

1. It allows systemd to control the main process without any other middleman.
2. It pushes logs from stdout directly into the journald.
3. It can be somewhat tuned.
4. It can handle more than one liquidsoap only by changing service suffixes.

[juanamm]

@vitoyucepi , at the beginning I had some doubts, but then I solved them by myself and your daemon works perfectly.
Thank you, you're a genius. 💯

[vitoyucepi]

Here's another example of how you could organize your liquidsoap project directory.

/home/icecast2/liquidsoap/
└── main
    ├── 00_settings.liq
    ├── 05_utils.liq
    ├── 10_encoders.liq
    ├── 10_environment.liq
    ├── 90_pipeline.liq
    ├── .env
    └── index.liq

The index.liq file will look like

%include "00_settings.liq"
%include "05_utils.liq"
%include "10_encoders.liq"
%include "10_environment.liq"
%include "90_pipeline.liq"

The /etc/systemd/system/[email protected] file should reflect the changes in the project structure

[Unit]
Description=Liquidsoap daemon for %I
After=network.target
Documentation=https://www.liquidsoap.info/

[Service]
Type=simple
User=icecast2
ExecStart=/home/icecast2/.opam/default/bin/liquidsoap /home/icecast2/liquidsoap/%I/index.liq
Restart=always

[Install]
WantedBy=multi-user.target

The override file also needs to be changed

[Service]
EnvironmentFile=/home/icecast2/liquidsoap/%I/.env

I didn't mention that you have to disable and stop the previous liquidsoap instance systemctl disable --now main-liquidsoap.service.

I believe that utilizing systemd user services instead of system services is also an option.

[juanamm]

@vitoyucepi nothing works for me anymore. :(
I cleaned all references to the deprecated daemon, deleted the directory and after I rebooted liquisoap didn't work anymore.
The script is still identical to the last one I shared with you, but it gives this error:

Sep 01 06:18:01 ip-18-xx-xx-xxx liquidsoap[5378]: At line 1, char 0:
Sep 01 06:18:01 ip-18-xx-xx-xxx liquidsoap[5378]: Error 3: Syntax error!
Sep 01 06:18:07 ip-18-xx-xx-xxx liquidsoap[5379]: At line 1, char 0:
Sep 01 06:18:07 ip-18-xx-xx-xxx liquidsoap[5379]: Error 3: Syntax error!

Sep 01 06:18:13 ip-18-xx-xx-xxx liquidsoap[5380]: Error 3: Syntax error!

I found that error with this command: journalctl -u liquidsoap@mainservice

It would be a good idea to add a file log to the liquidsoap daemon or script to see things better.
I've been at this for hours, I uninstalled liquidsoap and all the opam packages, I reinstalled everything but that error is still there running in a loop until I get console paralyzed (CPU 100%).
Most likely a silly bug, but I couldn't fix it.
I've been trying for +6 hours.

[vitoyucepi]

Probably, the file is empty or something.

ExecStart=/home/icecast2/.opam/default/bin/liquidsoap /home/icecast2/liquidsoap/%I.liq

Could you please let me know what is inside the file located at /home/icecast2/liquidsoap/main.liq?

[vitoyucepi]

Is it liquidsoap@mainservice or [email protected]?
mainservice looks for /home/icecast2/liquidsoap/mainservice.liq.
main looks for /home/icecast2/liquidsoap/main.liq.

[juanamm]

Is it liquidsoap@mainservice or [email protected]? mainservice looks for /home/icecast2/liquidsoap/mainservice.liq. main looks for /home/icecast2/liquidsoap/main.liq.

I made a silly mistake with service's name and paid dearly for it, thank you very much for noticing it.
Yesterday I was very tired and instead of enabling [email protected] I enabled liquidsoap@mainservice.
Everything worked again immediately.

[juanamm]

Now, I am creating a configuration to add a few lines in the service file to create a log file.
Following the logic that you have applied previously, I did not want to edit a service file /etc/systemd/system/[email protected], but I followed the technique of doing it through Override service file, as we did with the environments.

1. sudo systemctl edit [email protected]
   There was the expected content:

 [Service]
EnvironmentFile=/home/icecast2/liquidsoap/%I.env

2. Below that line I added:

ExecStartPre=/bin/mkdir -p /home/icecast2/liquidsoap/log
ExecStartPre=/bin/chown icecast2:icecast2 /home/icecast2/liquidsoap/log
ExecStartPre=/bin/chmod 750 /home/icecast2/liquidsoap/log
ExecStart=/home/icecast2/.opam/default/bin/liquidsoap --config /home/icecast2/liquidsoap/liquidsoap.conf /home/icecast2/liquidsoap/%I.liq
StandardOutput=file:/home/icecast2/liquidsoap/log/registro.log
StandardError=file:/home/icecast2/liquidsoap/log/registro.log

Note: Before step 2., I had created a config file in/home/icecast2/liquidsoap/liquidsoap.conf
With this content:

set("log.file", true)
set("log.file.path", "/home/icecast2/liquidsoap/log/registro.log")

3. Reload service file: sudo systemctl daemon-reload
4. Restart service: sudo systemctl restart [email protected]
5. I got the following error:

Failed to restart [email protected]: Unit [email protected] has a bad unit file setting.
See system logs and 'systemctl status [email protected]' for details.

6. systemctl status [email protected]
   Warning: The unit file, source configuration file or drop-ins of [email protected] changed on disk. Run 'systemctl daemon-reload' to reload units.

   └─391 /home/icecast2/.opam/default/bin/liquidsoap /home/icecast2/liquidsoap/main.liq

7. As the warning advised me to reload unit, repeated step 3 again with: sudo systemctl daemon-reload

8. Returned restart from step 4: sudo systemctl restart [email protected]
   But that warning and the error still keep coming out:
   Warning: The unit file, source configuration file or drop-ins of [email protected] changed on disk. Run 'systemctl daemon-reload' to reload units.
   Loaded: bad-setting (Reason: Unit [email protected] has a bad unit file setting.)

Do you have any idea what I have set wrong?

Edit:
Reasoning there may be a conflict between ExecStart of the service file and the one I configured in Override service file.

/etc/systemd/system/[email protected]
content:
ExecStart=/home/icecast2/.opam/default/bin/liquidsoap /home/icecast2/liquidsoap/%I/index.liq

systemctl edit [email protected]
content:
ExecStart=/home/icecast2/.opam/default/bin/liquidsoap --config /home/icecast2/liquidsoap/liquidsoap.conf /home/icecast2/liquidsoap/%I.liq

[vitoyucepi]

There are some errors.

1. [email protected]: Service has more than one ExecStart= setting, which is only allowed for Type=oneshot services. Refusing

   ExecStart=
   ExecStart=something

2. These options redirect stdout and stderr to files.

   StandardOutput=file:/home/icecast2/liquidsoap/log/registro.log
   StandardError=file:/home/icecast2/liquidsoap/log/registro.log

   I think you don't need this config

   settings.log.file := true
   # set("log.file", true) 
   settings.log.file.path := "/home/icecast2/liquidsoap/log/registro.log"
   # set("log.file.path", "/home/icecast2/liquidsoap/log/registro.log")

3. Are you sure about file? Why not append?

   StandardOutput=file:

   For me, the best way is to store everything in the journald.
   I prefer journalctl -u liquidsoap@main.
   Additionally, I do not require logrotate for file management.

4. ExecStartPre=/bin/mkdir -p /home/icecast2/liquidsoap/log
   ExecStartPre=/bin/chown icecast2:icecast2 /home/icecast2/liquidsoap/log
   ExecStartPre=/bin/chmod 750 /home/icecast2/liquidsoap/log

   To replace the commands, utilize tmpfiles.d.

   d	/home/icecast2/liquidsoap/log	0750	icecast2	icecast2	-
   

[juanamm]

I have read your advice carefully and I am going to do it the way you have proposed, it makes sense.
Thank you so much.

[juanamm]

I'm going to make a comment for all those who are migrating from v. 2.1.4 to 2.2.0, regarding UTF-8 encoding for Icecast2 to support Cyrillic characters.
The encoding must be done directly in the icecast2 XML in this way (suppose output mount point name is /stream):

<mount type="normal">
   <mount-name>/stream</mount-name>
   <charset>UTF-8</charset>
 </mount>

And in Liquidsoap output.icecast omit the parameter: encoding="UTF-8",

output.icecast(
    ...
    mount="stream", 
    ...
)

I mention this because it took me hours to figure out how to do it correctly.
If I left this configuration in liquidsoap:

output.icecast(
    ...
    encoding="UTF-8",
    mount="stream", 
    ...
)

and set

<mount type="normal">
   <mount-name>/stream</mount-name>
   <charset>UTF-8</charset>
 </mount>

to icecast2, got metadata with correct cyrillic characters, but streaming audio didn't work.
If I commented out the Icecast2 configuration like this:

<!-- 
<mount type="normal">
   <mount-name>/stream</mount-name>
   <charset>UTF-8</charset>
 </mount>
-->

Streaming audio played but Cyrillic character metadata was displayed incorrectly:
'МОТ - Август - это &#10'

When doing these tests I realized that the configuration of the mount point (in my case /stream) was being duplicated by the line: encoding="UTF-8",
After trial and error I was able to solve the problem in the way that I mentioned before.
Now, the cyrillic metadata is displayed correctly:

Amirchik - Эта любовь
ANNA ASTI - По барам
Hillsong 日本語 - ディス・イズ・リビング
