Problems in MythBackend.php for mythweb

[ChrisLaw]

Hi there.
As per the guidelines -
I'm using
Description: Ubuntu karmic (development branch)
Release: 9.10
the package is
apt-cache policy mythweb
mythweb:
  Installed: 0.22.0~trunk22242-0ubuntu1
  Candidate: 0.22.0~trunk22242-0ubuntu1
  Version table:
 *** 0.22.0~trunk22242-0ubuntu1 0
        500 http://archive.ubuntu.com karmic/multiverse Packages
        100 /var/lib/dpkg/status

I didn't think that I'd be able to gather this information properly using apport.

The problem is shown when I load the first page from mythweb on my backend system -

ie http://myhost/mythweb/tv/list

The page starts with 2 errors. The first is

User Notice at /usr/share/mythtv/mythweb/classes/MythBackend.php, line 124:
Failed to set php timezone to BST Response from backend was Array ( [0] => BST [1] => 3600 [2] => 2009-10-07T23:48:41 )

As far as I can make out, the problem is with

if (!@date_default_timezone_set($_SESSION['backend']['timezone']['value']))
from the MythBackend.php file. The value it is trying to set is BST (the first element in the array above) but that is failing, for reasons unknown. I put in a line forcing it to use "Europe/London" instead, and the error went away. This could be a problem in php rather than mythweb I guess.

Thanks,
Chris

I'll raise the second php error as another bug, as I don't think it's related.

I tracked down the problem. When I tried to connect with a seperate frontend, it was dying complaining that the server timezone was different - BST instead of Europe/London. So I checked, and /etc/localtime was different on the 2 machines. The server has been ubuntu since about version 6.04, whereas the client is a fresh install. So I'm assuming that at some point in the past, /etc/localtime was set up to use BST. I changed it to a symlink to /usr/share/zoneinfo/Europe/London, that fixed the frontend connection problem. I then undid the change I'd made to MythBackend.php, and that now works with the new timezone value too. Whether this just moves the bug or clears it I don't know.

I experienced the same issue -- existing box, upgraded to Karmic, suddenly saw timezone warnings from php in MythWeb. The following fixed it:

sudo dpkg-reconfigure tzdata
