MPD dumps core on play

[Rafaeltheraven]

Bug report

Describe the bug

Since a few days now, MPD has randomly started coredumping whenever I try to play anything. This happens on the current release version. If I use the master branch version it simply crashes on startup.

I am running ArchLinux and using pipewire 0.3.59 for audio.

Expected Behavior

MPD plays audio

Actual Behavior

MPD coredumps

Version

Music Player Daemon 0.23.9 (0.23.9)

Configuration

# An example configuration file for MPD.
# Read the user manual for documentation: http://www.musicpd.org/doc/user/

# Files and directories #######################################################
#
# This setting controls the top directory which MPD will search to discover the
# available audio files and add them to the daemon's online database. This 
# setting defaults to the XDG directory, otherwise the music directory will be
# be disabled and audio files will only be accepted over ipc socket (using
# file:// protocol) or streaming files over an accepted protocol.
#
music_directory         "~/Music"
#
# This setting sets the MPD internal playlist directory. The purpose of this
# directory is storage for playlists created by MPD. The server will use 
# playlist files not created by the server but only if they are in the MPD
# format. This setting defaults to playlist saving being disabled.
#
playlist_directory              "~/.mpd/playlists"
#
# This setting sets the location of the MPD database. This file is used to
# load the database at server start up and store the database while the 
# server is not up. This setting defaults to disabled which will allow
# MPD to accept files over ipc socket (using file:// protocol) or streaming
# files over an accepted protocol.
#
db_file                 "~/.mpd/database"
# 
# These settings are the locations for the daemon log files for the daemon.
# These logs are great for troubleshooting, depending on your log_level
# settings.
#
# The special value "syslog" makes MPD use the local syslog daemon. This
# setting defaults to logging to syslog.
#
log_file                        "~/.mpd/log"
#
# This setting sets the location of the file which stores the process ID
# for use of mpd --kill and some init scripts. This setting is disabled by
# default and the pid file will not be stored.
#
pid_file                        "~/.mpd/pid"
#
# This setting sets the location of the file which contains information about
# most variables to get MPD back into the same general shape it was in before
# it was brought down. This setting is disabled by default and the server 
# state will be reset on server start up.
#
state_file                      "~/.mpd/state"
#
# The location of the sticker database.  This is a database which
# manages dynamic information attached to songs.
#
sticker_file                    "~/.mpd/sticker.sql"
#
###############################################################################

# General music daemon options ################################################
#
# This setting specifies the user that MPD will run as. MPD should never run as
# root and you may use this setting to make MPD change its user ID after
# initialization. This setting is disabled by default and MPD is run as the
# current user.
#
#user                           "nobody"
#
# This setting specifies the group that MPD will run as. If not specified
# primary group of user specified with "user" setting will be used (if set).
# This is useful if MPD needs to be a member of group such as "audio" to
# have permission to use sound card.
#
#group                          "nogroup"
#
# This setting sets the address for the daemon to listen on. Careful attention
# should be paid if this is assigned to anything other then the default, any.
# This setting can deny access to control of the daemon. Not effective if
# systemd socket activiation is in use.
#
# For network
bind_to_address         "localhost"
#
# And for Unix Socket
#bind_to_address                "~/.mpd/socket"
#
# This setting is the TCP port that is desired for the daemon to get assigned
# to.
#
#port                           "6600"
#
# This setting controls the type of information which is logged. Available 
# setting arguments are "default", "secure" or "verbose". The "verbose" setting
# argument is recommended for troubleshooting, though can quickly stretch
# available resources on limited hardware storage.
#
#log_level                      "default"
#
# Setting "restore_paused" to "yes" puts MPD into pause mode instead
# of starting playback after startup.
#
#restore_paused "no"
#
# This setting enables MPD to create playlists in a format usable by other
# music players.
#
#save_absolute_paths_in_playlists       "no"
#
# This setting defines a list of tag types that will be extracted during the
# audio file discovery process. The complete list of possible values can be
# found in the user manual.
#metadata_to_use        "artist,album,title,track,name,genre,date,composer,performer,disc"
#
# This example just enables the "comment" tag without disabling all
# the other supported tags:
#metadata_to_use "+comment"
#
# This setting enables automatic update of MPD's database when files in 
# music_directory are changed.
#
auto_update     "yes"
#
# Limit the depth of the directories being watched, 0 means only watch
# the music directory itself.  There is no limit by default.
#
#auto_update_depth "3"
#
###############################################################################

# Symbolic link behavior ######################################################
#
# If this setting is set to "yes", MPD will discover audio files by following 
# symbolic links outside of the configured music_directory.
#
follow_outside_symlinks "yes"
#
# If this setting is set to "yes", MPD will discover audio files by following
# symbolic links inside of the configured music_directory.
#
follow_inside_symlinks          "yes"
#
###############################################################################

# Zeroconf / Avahi Service Discovery ##########################################
#
# If this setting is set to "yes", service information will be published with
# Zeroconf / Avahi.
#
#zeroconf_enabled               "yes"
#
# The argument to this setting will be the Zeroconf / Avahi unique name for
# this MPD server on the network. %h will be replaced with the hostname.
#
#zeroconf_name                  "Music Player @ %h"
#
###############################################################################

# Permissions #################################################################
#
# If this setting is set, MPD will require password authorization. The password
# setting can be specified multiple times for different password profiles.
#
#password                        "password@read,add,control,admin"
#
# This setting specifies the permissions a user has who has not yet logged in. 
#
#default_permissions             "read,add,control,admin"
#

# Audio Output ################################################################
#
# MPD supports various audio output types, as well as playing through multiple 
# audio outputs at the same time, through multiple audio_output settings 
# blocks. Setting this block is optional, though the server will only attempt
# autodetection for one sound card.

It broke for me as well (after installing updates). After messing around a bit, changing my audio_output type from alsa to pulse fixed it for me, however you don't seem to even have an audio output configured in the first place..?

I'm running Pipewire on arch btw™ as well.

Here is my working config:

.config/mpd/mpd.conf

``` db_file "~/.local/share/mpd/database" log_file "~/.local/share/mpd/log" music_directory "~/mus" playlist_directory "~/.local/share/mpd/playlists" pid_file "~/.local/share/mpd/pid" state_file "~/.local/share/mpd/state" sticker_file "~/.local/share/mpd/sticker.sql" auto_update "yes" bind_to_address "[::]:6600" bind_to_address "~/.local/share/mpd/mpd.sock" restore_paused "yes" max_output_buffer_size "16384" audio_output { type "pulse" name "Pipewire Playback" } audio_output { type "fifo" name "Visualization" path "/tmp/mpd.fifo" format "44100:16:2" } ```

Hope this helps!

[Rafaeltheraven]

AFAIK you don't have to specify an output, it can autodetect one (alsa in my case). I had the same problem when using pulse as an output, but I'll have a look at your conf

There's suspect code in AlsaOutputPlugin.cxx, these alsa api calls may return NULL and are passed as args to FmtDebug which will then result in this exception:

terminate called after throwing an instance of 'fmt::v9::format_error'
  what():  string pointer is null

    snd_pcm_format_name(hw_result.format),
    snd_pcm_format_description(hw_result.format));
    snd_pcm_name(pcm),
    snd_pcm_type_name(snd_pcm_type(pcm)));

The results should probably be checked for NULL before being passed to FmtDebug, although the reason why NULL is being returned is probably the more significant issue. May be alsa lib version issue?

[ykahveci]

For reference, some of my relevant package versions are:

• alsa-lib is on 1.2.7.2-1
• mpd is on 0.23.9-3
• pipewire(-*) is on 1:0.3.59-2

[Rafaeltheraven]

I've moved to using the pulse sink and now it works (which is odd because when I was initially testing this it didn't work). Probably something wrong in alsa yeah. I'm also using alsa-lib 1.2.7.2-1.

Should I close this issue or do we want to convert it into an alsa related issue instead?

[MaxKellermann]

It is not explicitly documented whether snd_pcm_name() is allowed to return NULL: https://www.alsa-project.org/alsa-doc/alsa-lib/group___p_c_m.html#ga5031edc0422df8db1f70af056a12dd77 But apparently this is legal: https://github.com/alsa-project/alsa-lib/blob/0222f45d11e8b71bf651b985b00fdb0addbf3eed/src/pcm/pcm.c#L2761-L2762 That's ... surprising!
