"no such file or directory" in update.py about pidora HOT 21 CLOSED

Have you edited the setting inside update.py? There's a directory config inside it.

Very cool project, but I'm having some trouble. I've done this twice on
two different raspbian installs, neither one works.

Pianobar works fine, and in the browser, the index.php comes up, but it
never gets past " Hello There Pianobar is starting up..."

I am not using midori from localhost, I'm hitting it from another
computer, while ssh in to RPi to see what's going on.

Here's what's happening on pianobar console -- this demonstrates that
it is picking up my config file, where i've specified the fifo and the
update.py location. Furthermore, when I change the config entry (thats
supposed to point to update.py) to a nonexistent file, I get a
different error.

Welcome to pianobar (2012.05.06)! Press ? for a list of commands.
(i) Control fifo at /var/www/ctl opened
(i) Login... Ok.
: No such file or directory
(i) Get stations... Ok.
: No such file or directory

Then it starts playing my playlist. But index.php page still shows
"hello there..."

Any ideas?

Thanks

Yes, I've edited the "www" variable in the python script to point to the
root of pidora.

I've just placed all the pidora files into /var/www/*

So the variable is set to "/var/www/"

Thanks!

Alright, I'll take a look at it later tonight. Thanks for reporting it!

Thanks. Let me know if there's anything else you need to know about my
environment etc.

So it seems like pianobar is the one throwing the error. If python was complaining, there would be something like:

Traceback (most recent call last):
  File "/home/jacob/.config/pianobar/update.py", line 50, in <module>
    open(www + "stationList", "w").write(stations)
IOError: [Errno 2] No such file or directory: '/home/jac/www/pianobar/stationList'

And since it was able to load the ctl file, I'm guessing it had trouble locating update.py. So I would check to make sure that my event_command setting in pianobar's config file was correct. Like ensuring that it's hard-coded and not relative, etc.

This is just my guess though. You're using an older version of pianobar. The one that I have (2012.09.07) will say /!\ Cannot start eventcmd. (No such file or directory) if the above was true.

from pidora.

So here are 3 scenarios:

1. I point event_command to the wrong (nonexistent) file: /!\ Cannot
   start eventcmd. (No such file or directory)
2. I comment out event_command from pianobar config: No error message
3. I point eventcmd to the right update.py file: it plays fine and in
   between every song pianobar console says "No such file or directory" = a
   different error message, it does not have "/!\ Cannot start eventcmd" as
   part of the error message.

I've messed with this for hours but as you say its clearly not a python
error... is there a way to set a higher level of debug with pianobar that
you're aware of?

I'd love to get this working, so I guess I'll keep tinkering. Thanks!

No I don't know of any other higher debug flags you can set. At least the pianobar docs don't mention any.

I think what I would try to do next is build the latest pianobar and test that. Because I have absolutely no clue.

from pidora.

I love what I see Jacob, and hope I can overcome the user error on my part to get it working.

I am using pianobar (2013.05.19) on arch linux arm on a rpi and same issue here. It it never gets past " Hello There Pianobar is starting up...", no album or song info is displayed, and ": No such file or directory" 3 times before the first song plays and once after each song starts in the console.

Is there any chance this has anything to do with where the directory /albumart is located?

I did not use the install script.. but reviewed it while troubleshooting this. The script contains:
mv pidora/ www/
mkdir www/albumart/
I'm a bit of a linoob, but doesn't that put /albumart and /pidora at the same level within /www? I read the README to put /albumart into the /pidora directory... maybe it doesn't matter bc when I moved /albumart, same issue.

Also, the controls on mobile.php work, but no song info. I can Pause Next Love Ban and Tired any tune from that page (but no joy on index.php).

Weird huh?

Probably some permissions issue unresolved.

Thank you.

Yeap that's a typo. It's now fixed.

Could you post a gist of your .config/pianobar/config file? Because this is strange.

Hey, I built pianobar from source and still have the same problem.

Welcome to pianobar (2013.05.19)! Press ? for a list of commands.
(i) Control fifo at /var/www/ctl opened
(i) Login... Ok.
: No such file or directory
(i) Get stations... Ok.
: No such file or directory

from pidora.

Thought this was interesting -- when I just try to run update.py from console, it gives the same error.

pi@poolside /var/www/pianobar-eventcmd $ ./update.py
: No such file or directory

from pidora.

as opposed to

pi@poolside /var/www/pianobar-eventcmd $ python update.py
Traceback (most recent call last):
File "update.py", line 12, in
event = sys.argv[1]
IndexError: list index out of range

which looks like what we would expect...

from pidora.

@MrDadaGuy: could you post what kind of permissions that update.py has? ls -l may give you them.

from pidora.

Actually no, do a whereis env on the command line and paste what that gives you.

SOLVED: dos2unix to the rescue!!

http://www.linuxcommand.org/man_pages/dos2unix1.html

The update.py script had some bad line feed characters in there. Not sure if that was from your code or if i introduced it.. but that solved things for me :)

Thanks!!!

BTW - what should have tipped me off sooner... the error ": No such file or directory" is usually preceeded by the file it's trying to access. So if I had a bad file after "/usr/bin/env python" like "/usr/bin/env python badfile" it would have said "badfile: No such file or directory". So the absence of any descriptor there should have tipped me off we're dealing with an invisible character such as a bad line feed or carriage return. I guess it did tip me off eventually. Anyway good work my friend. thanks

from pidora.

What the crap.

Thanks for figuring it out. 😌 I think I few others also had the same issue so I'll direct them to your comment. And I'll also run the command on update.py and update the repo.

Thanks again!

@emcquaid: Does @MrDadaGuy's solution work for you?

from pidora.

Yes. Fixed. and then fixed the tab space indent issue mentioned in #18 and now it's working fantastically. Thank you. Such a cool app.
