Airtime 2.1.2 hotfix patch out now - Airtime Support Discussions on Sourcefabric Forum

Adam Thomas · Post edited by Adam Thomas at 2012-06-19 07:11:45

Hi everyone,

Avid forum followers will have spotted that on Friday night we found an issue introduced in our 2.1.1 patch that required a rapid hotfix.

We made the one-line change yesterday, packaged it as Airtime 2.1.2 and rolled it out. Most of you will have been notified via the update notifier. It fixes our Pypo scheduler so that it correctly retrieves the program schedule after extended periods of inactivity by the user.

Install and upgrade guides can be found on the Airtime download page.

Thanks, Adam

Upgrade completed correctly. Feedback will follow.

Thanks for great support!

I updated from 2.1.0 to 2.1.2 and now I can't add any shows to the calendar. The add show box just goes grey - see attached screenshot.

Nevermind, I think I missed out this step:

sudo -u postgres dropdb airtime

Hi James,

It's all good now?

Martin Konecny

Me and James Dunn worked together to fix this problem. Somehow his database row id's became unsynchronized from the row id sequence table filling the postgresql logs with entries similar to:

2012-06-21 16:44:00 BST ERROR: duplicate key value violates unique constraint "cc_show_pkey"

2012-06-21 16:44:00 BST DETAIL: Key (id)=(10) already exists.

Not sure if this is an Airtime bug at the moment since we don't have any code that manages these sequence tables (Postgresql handles it automatically). Ticket created here: http://dev.sourcefabric.org/browse/CC-3999

Someone has managed to install and operate 100% versions 2.1.1 and 2.1.2 on a VPN server? Unfortunately I could not, and every form of installation returns a different problem. I tried Ubuntu and Derbi. No works! I'm going back to version 2.0.3 it worked perfectly

@Edilson,

We would be more than happy to resolve your problem with 2.1.

I believe the issue you may be having is that many VPN's dont come with a locale defined. In 2.0 we let this slide but ultimately it caused too many problems with files and unicode characters. Therefore 2.1 is much more strict in this regard. If you show us the install errors we'll see what we can do.

If you can help, I found that in all error situations the folder var/lib/airtime does not exist.

The Airtime would be an awesome program if it worked well and had good support. Still has much to do in this program. I think I'll stick with the same old version. I see that nobody knows how to solve problems.

Reply to @Edilson+R+Chiquetano:

Your problem has already been solved by our support team in this same forum.

Edilson R Chiquetano

Martin,

None of this works on my VPS server. Only works the installation of 2.0.3 on Debian Airtime 6.

• Automated installation

Airtime 2.0.3 on Debian 6.0 - OK

Airtime 2.0.3 on Ubuntu 10.04 and 11.04 and 11.10 - Error

Airtime 2.1.2 on Debian 6.0 - Error

Airtime 2.1.2 on Ubuntu 10.04 and 11.04 and 11.10 - Error

Tip:

1 - Installing the same version 2.1.2 installing version 2.0.3 or the creation of a tutorial and to solve all the problems of install mode. A good program like this can not have problems with install mode.

2 - Include in next version, the option to relay other radios in the day and time scheduled.

Martin Konecny

@Edilson,

The error message is right here in your log:

"createdb: database creation failed: ERROR: new encoding (UTF8) is incompatible with the encoding of the template database (SQL_ASCII) "

Your database is using ASCII, whereas it is supposed to be using UTF8. In Airtime 2.0.x we naively allowed this but it causes too many problems, and as a result has been disabled for 2.1.x. If you attempt to upload a file with UTF8 metadata in 2.0, you will be in for a unpleasant surprise.

Edilson R Chiquetano

@Martin,

Ok I understand the problem.

Do you have corrected a problem and created a new problem. Ideally, the Airtime work properly without these errors.

What should I do to use the version 2.1.2?

So far no one has posted a solution that really works.

You think I should give up using version 2.1.2 and other future releases?

Martin Konecny

This is the only way to fix the problem unfortunately:

http://stackoverflow.com/questions/380924/how-can-i-change-database-encoding-for-a-postgresql-database-using-sql-or-phppga

Or if your postgresql database isn't storing any data, then simple do

sudo apt-get purge postgresql

and then

sudo apt--get install postgresql

I upgraded to 2.1.2 with apt-get but found On Air light was off and restarting the airtime-playout service did not help. After reboot everything was running again. Not sure why that happened.

Reply to @Swidch+Swidcheg:

Our MP3 validator is a little over-zealous at the moment and will deny MP3 files for the tiniest issue. We've relaxed the errors that can happen for 2.1.3.

Hello Martin and other Developers,

I have installed airtime 2.12 on my debian 6.05 and your nice webapp works fine.

I have troubles with adding of my mounted partition (/mnt/music/bands/albums/files.mp3) to media folders.

I can add only a new files with your drag&drop uploader, another folder are everytime empty (ajax loader does hang - it don´t accept my selected folder in main directory or watched folders). The trick with %20 for spaces doesn´t work for me.

Cheers tom

Martin Konecny

Please take a look in /var/log/airtime/media-monitor/media-monitor.log for anything suspicious.

I found only these errors :

Hi,

This appears to be a bug that happens with python 2.6, and a files with strange characters in your watched directory.

Upgrading to python 2.7 appears to fix this. You can also hunt through your music directory for any files with strange characters in their filename, and try removing these.

For our next version of Airtime we'll look into a better way to get around this bug.

Martin Konecny · Post edited by Martin Konecny at 2012-07-14 17:35:41

On second thought, I believe the problem here is that you have some files on your filesystem that have an invalid filename encoding (not a Python 2.6 bug).

First, what is the output of "locale" (type this into your terminal)?

Howdy, Stranger!
