alip / mpdcron Goto Github PK

I am on mac osx (10.9.1), I did the following

git clone https://github.com/alip/mpdcron.git

cd mpdcron

./configure

No such file or directory

Also I have installed required packages libdaemon-0.13 or newer libmpdclient-2.1 or newer glib-2.18 or news

even compiled autotools

I have no idea what I'm missing here :(

I run the mpdcron, I can see it running, but I cannot find "eugene" "walrus" or any other process to make a query

my use case is pretty specific though, while playback, with every song change I want to query the MPD_STATUS_AUDIO_FORMAT_BITS. If 16, then execute a command, if 24 execute other command.

Will appreciate the help

This is Debian bug #573805 (http://bugs.debian.org/573805).

More info available at the URL above, but basically:

From this up a repeating pattern starting with the last select can be
seen.

Occasionally some lines like:
[pid 26832] mremap(0x7f201096e000, 458752, 462848, MREMAP_MAYMOVE) = 0x7f201096e000
or
[pid 26832] brk(0x2bd7000) = 0x2bd7000
come along. They show that mpdcron grows in memory size.

Since mpdcron continues to read data from mpd (very slowly), it is
probably not an infinite loop, but a slow algorithm. The loop seems to
be getting slower over time which suggests an O(n^2) algorithm. I should
probably mention that my playlist currently has around 10000 entries.
You can easily create such a playlist by concatenating a playlist to
itself often enough. After eleven minutes of watching mpdcron read a
playlist I gave up and killed it, because two songs already passed by.

Furthermore I verified that disabling the stats module does not solve
the problem.

A quick check of the source shows that it probably blows up in
env_list_all_meta, because it uses strftime (and thus doing all those
stat calls) and using g_setenv in a loop and thus being an O(n^2)
algorithm.

The bad thing about this is that there is no easy way to solve this
problem, because the real problem didn't even show up: Let us assume
10500 playlist entries with each of them having a filename of 60
characters. For each entry two variables are added, which should take
another 40 characters only counting the lengths of their names. So a
lower bound for the size of the environment would be 1MB. This size may
not be supported by the operating system, so the whole approach of
feeding the playlist via the environment is flawed. Using g_setenv in a
loop only makes things break at an earlier point.

Given that it requires a large playlist I downgraded the severity to
normal. I hope this helps for solving the issue.

Homescrape does not work unless I include "require 'date'" (I use archlinux) . Please make the change in git.

On Arch Linux, I performed the following curl upgrade:

upgraded curl (7.21.3-1 -> 7.21.4-2)

As you can see, on song changes, nothing gets really submitted:

The option and playlist hooks would be very very helpful for me.

I read the bug report about it. I don't know if there is always the need for transfering so much data. For me is only the hook call of option/playlist needed.

With
$ homescrape hariskar
nothing happens. Any idea why?
I use Archlinux

I'd love to be able to listen to my I large-ish music collection (kept on a headless mpd server) even when I lose network connectivity, and without having to tend to a local mirror as my collection evolves.

What I envision is essentially a local music cache: Earmarking a storage area (e.g. 3GB) on my mobile device or laptop, and then having that space automatically fill with the most recent songs played by mpd (which will approximate those I'm most likely to want to hear again soon). Once the area's full, the song least-recently played by mpd would be overwritten.

Has this or something like it been done? Could an mpdcron configuration help to achieve it? Would that require a new mpdcron module? Is there a forum better-suited to this post, to keep this issue tracker free of overly ambitious feature requests?

I'd welcome responses to any of these questions!

Sometimes mpdcron does not work (I'll elaborate in a while). Without --verbose and --log options, it's next to imposible to track what's happening or what certainly is wrong. Please add them, it would be very helpful.
Or, if these are already present, please add note in -h and/or man page and/or mpdcron.conf file.

OK, speaking of my strange behavior, there is a log from console:

First of all thanks for a great utility

I only have one gripe and that's the amount of logging I am getting for such things as scrobbling activity, my main logs are being flooded with this activity.

I can't seem to find a way of addressing this, there is nothing available in the conf file to set logging levels and no documentation on what is available. If there isn't an option can one be added please, if there is then please tell me what it is and how it works.

Thanks again for this very useful app which I am using to generate coverart and lyrics files on song changes, previously I had to poll mpd continuously to find out what is happening.

$ mpdcron
Daemon returned 2 as return value

When mpdcron runs as a daemon it does not save the stats. however when i run it as mpdcron -n then the stats get saved.

When I try to run mpdcron it just says "daemon returned 2 as return value". Using arch linux, issue occurs both in the AUR package as well as when I compile it myself. No error is given when mpdcron -n is run

Using the notification module, when I listen to a song it is displayed in a notification bubble. However, there is a set time before which the bubble won't disappear. If, before that time passes, I play another song, the notification for playing that song isn't shown until the one for the previous song has disappeared, whereas it should in fact update the notification bubble for the previous song.

(Note: this bug is the same as was present in the Panflute GNOME panel applet: https://bugs.launchpad.net/panflute/+bug/471499, so the error is not in notify-osd but in mpdcron.)

In case of player event commands in .../hooks/player are executed twice.

This is important for users.

The stats module is the most interesting part of mpdcron for me, however, I'm having trouble configuring it.

I have the following dependencies installed:

sqlite3 v3.6.23.1
ruby 1.9.1p378
nokogiri 1.4.1

I'm running ArchLinux and can't find a package for gio. Perhaps gvfs?

My config file is just as standard.

mpdcron launches fine, similarly for walrus to update. I'm not so sure about eugene however. I get errors if I run something like:

$ eugene list radiohead
Failed to list song: EOF while trying to read a line

$ eugene listtags
Failed to list tags of current playing song: you don't have permission for "listtags"

Also, with homescrape I get:

Sorry for the naïvety of this post.

When a new song begins, the hooks/player is executed twice, instead of only once.
When I change a song manually, it's executed once as expected.

Is it something you can look into?
