Headphones Fails to Start

[eangulus]

Running Ubuntu Server 14.04 Fully upto date including headphones git.

Get the following error when typing python heandphones.py

Traceback (most recent call last):

[basilfx]

Strange. I run Headphones under 14.04 too, and it works.

Could you try the following: cd to the headphones lib/ folder. Then spawn a python shell and type: import unidecode.

[basilfx]

I can confirm the current develop branch works as expected. I cannot reproduce the bug.

Possible causes:

• missing files (corrupted clone?)
• old *.pyc files

[eangulus]

Did the import thing.

still get this:

karen@SERVER-KARRAWA:~/.headphones$ python Headphones.py

[eangulus]

I am happy to reinstall this, but don't want to loose the database. What files do I need to keep?

[eangulus]

Also happy for you to remote login and see for yourself.

[basilfx]

Well, if all is OK, you should have a file called ROOT/lib/unidecode/__init__.py. It should not be empty.

If you want to do a reinstall, please check the Troubleshooting wiki, under auto update section.

[eangulus]

I have the file. Contents are:

-- coding: utf-8 --

"""Transliterate Unicode text into plain 7-bit ASCII.

Example usage:

from unidecode import unidecode:
unidecode(u"\u5317\u4EB0")
"Bei Jing "

The transliteration uses a straightforward map, and doesn't have alternatives
for the same character based on language, position, or anything else.

In Python 3, a standard string object will be returned. If you need bytes, use:

unidecode("Κνωσός").encode("ascii")
b'Knosos'

from sys import version_info

Cache = {}

def unidecode(string):

                    "Passing an encoded string will likely have "
                    "unexpected results." % (type(string),),
        RuntimeWarning, 2)

retval = []

    codepoint = ord(char)

    if codepoint < 0x80: # Basic ASCII
        retval.append(str(char))
        continue

    if codepoint > 0xeffff:
        continue # Characters in Private Use Area and above are ignored

    section = codepoint >> 8   # Chop off the last two hex digits
    position = codepoint % 256 # Last two hex digits

    try:
        table = Cache[section]
    except KeyError:
        try:
            mod = __import__('unidecode.x%03x'%(section), [], [], ['data'])
        except ImportError:
            Cache[section] = None
            continue   # No match: ignore this character and carry on.

        Cache[section] = table = mod.data

    if table and len(table) > position:
        retval.append( table[position] )

return ''.join(retval)

[eangulus]

Followed the Hard Reset instructions, and it started straight after, but then stopped again, and now when trying to start it shows this:

Traceback (most recent call last):
File "lib/cherrypy/_cprequest.py", line 656, in respond

OperationalError: unable to open database file

[eangulus]

Oh and the instructions said I wouldn't loose all my settings and database.

Why is it all currently empty and all settings are now reset?

[basilfx]

I think these errors are not the result of Headphones malfunctioning.

Are you sure there isn't another error causing this? Are your packages up-to-date? No disk errors? What if you try to open the database file with sqlite3 command line tool? Doest git fsck yield something problematic?

Also, the instructions also say that it should be tailored to your installation, and that you should backup your files, just in case.

[eangulus]

This is a new server, that has been running for about 3-4 months now with no problems at all.

All brand new drives, none are failing or report errors. All packages upto date. Runs Couchpotato, SickRage, supposedly Headphones and was for a while, VirtualBox with a XP VM starting on Boot, and Apache.

Everything else works fine, and it never gets tinkered with either. Its a dedicated box for the above and once I had finished setting up, the only thing I do with it is update the packages around once a week.

I do know a little linux, but not sure how to open sqlite stuff.

[basilfx]

This is what I just tested, and it works (fresh install):

Have you checked permissions?

[eangulus]

I would check permissions but as stated before, I have limited linux knowledge, and have no idea what I am looking at. So I can check the permissions, but I have no idea if they are right or wrong seeing I have no information on what they are suppose to be.

I did notice something strange and not sure if it might help in working this out.

The Startup script that started headphones on boot (and has been working fine until recently), now does not work at all. It will not start headphones. The only way I can start it at the moment is via the CLI using python headphones.py

[eangulus]

As noted before, contact me on my email info@eangulus.com and you can get SSH access to get any debug information allot faster.

[eangulus]

Also looking at what shows when I start via CLI, I see this line:

no talloc stackframe at ../source3/param/loadparm.c:4864, leaking memory

I don't know what it means but I don't think its a good thing.

[eangulus]

Now things are really getting confusing.

Just deleted (after backup) the headphones folder.
Followed a fresh install procedure in the Wiki.
All installed and works.

Started following Install as Daemon.
Got to the Adjust settings in /etc/default/headphones (installpath and run as user).

But file is there but empty. What am I suppose to be editing.

Also regarding lost config and database, in the /opt/headphones directory, there is a 8Mb Database and a config file with paths in it I recognize, but headphones doesn't seem to be using those. There is also a Artwork cache with heaps of stuff in it.

[basilfx]

The no talloc stackframe at ../source3/param/loadparm.c:4864, leaking memory is a Ubuntu/Samba bug. If you googled it, you should have encountered it.

For the /etc/default/headphones contents, see the comment section in this file: https://github.com/rembo10/headphones/blob/master/init-scripts/init.ubuntu

Regarding the /opt/headphones directory: you have to setup Headphones that it will use these folders and paths. If you run python Headphones.py -h, you'll see what is expected.

Lastly, the problem you describe is most certainly not Headphones related. Don't get me wrong, I'm glad to help you, but don't expect from me to learn you the basic Linux stuff to solve your problem. That would be too much if I would help everybody posting issues here. There are support forums on the internet that can help you a lot better with issues like these.

[eangulus]

Now having same issue on a totally differnet server, completly different hardware, different version of Ubuntu etc.

headphones fails to start.

But hey, its not a headphones issue.

[basilfx]

I never said it was not a Headphones issue, but only most unlikely. I draw that conclusion because this is the only issue I saw lately on this topic, and because I cannot reproduce this error. Again, don't get me wrong: I am glad to help.

Is there a possibility you can create a Virtual Machine (e.g. with VirtualBox) with the exact same installation steps, and share it with me? Also wondering, do you use the English (UTF8) as default system locale?

[reallistic]

I noticed in one of the previous posts you mention python 3. Please type the following in shell as basilfx mentioned:
python --version it should report 2.7.x (the x will be some other number).
If it does in fact report 3.x then this could be your issue. Some programs are simply not compatible with python 3. I am not sure however, if HP is one of them.
Try to start headphones using the following command instead:

python2.7 Headphones.py

[basilfx]

Closed due to no response.

[minipulator]

Having this problem myself. Just updated Headphones to current (13f34a1) and suddenly no start, lotsa errors, see below. What's interesting is that I checked out a whole new copy and still have the same problem, same error. Been running headphones for years, never had a problem before today. I'm testing it without using the init script, but same error either way. Tried develop branch, same thing. Running python 2.7.3 on Ubuntu 12.04 LTS. No rush or anything, but if I can help troubleshoot, let me know?
