Bug Description

Running 0.21-weekly fixes on 8.04.
Radar weather maps haven't shown up on mythweb since I did my original 0.20.2 / 7.10 Mythbuntu install. Finally getting around to figuring out why and looked in apache error.log, I see that mythweb was looking in /var/www/data/cache rather than /var/www/mythweb/data/cache for the radar image. I had to do the following to get it to work:

/var/www/data/cache$ sudo ln -s ../../mythweb/data/cache/SouthCentralDopplerRadar1800-0 SouthCentralDopplerRadar1800-0
/var/www/data/cache$ sudo ln -s ../../mythweb/data/cache/SouthCentralDopplerRadar1800-1 SouthCentralDopplerRadar1800-1
/var/www/data/cache$ sudo ln -s ../../mythweb/data/cache/SouthCentralDopplerRadar1800-2 SouthCentralDopplerRadar1800-2
/var/www/data/cache$ sudo ln -s ../../mythweb/data/cache/SouthCentralDopplerRadar1800-3 SouthCentralDopplerRadar1800-3
/var/www/data/cache$ sudo ln -s ../../mythweb/data/cache/SouthCentralDopplerRadar1800-4 SouthCentralDopplerRadar1800-4
/var/www/data/cache$

It is probably going to be close to beta time before I can try an 8.10 build, so I wanted to record this now on the chance it is an easy fix to get in sooner than later.

Confirmed. And easier symlink is sudo ln -s /var/www/mythweb/data/ /var/www/

mythweb.patch Edit (1.7 KiB, text/plain)

I am attaching a patch which might fix this issue. It's untested because I don't seem to be able to set up MythWeather on my backend.

To apply, download the patch to /var/ww/mythweb and run:

patch -p0 < mythweb.patch

Of course, please revert your symlinks beforehand ;)

With the patch, I get the following error within the browser:

Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING, expecting ',' or ';' in /usr/share/mythtv/mythweb/modules/weather/tmpl/default/weather.am.php on line 35

If I adjust line 35 of the patch from
+ echo "images[$i].src = \ getcwd() . "/". cache_dir ."/". $matches[1] ."-$i\";\n";
to be
+ echo "images[$i].src = \"" . getcwd() . "/". cache_dir ."/". $matches[1] ."-$i\";\n";

I no longer get a php error, but weather map doesn't show. /var/log/apache/error.log seems to indicate getcwd() points to /var/www/usr for some reason:

[Tue Sep 23 13:05:44 2008] [error] [client 127.0.1.1] File does not exist: /var/www/usr, referer: http://media/mythweb/weather

In trying to come up with another work-around, I noticed that these very lines of code have changed in upstream trunk. See:
http://svn.mythtv.org/trac/ticket/5171

Unfortunately that doesn't fix it either - it ends up pointing to the same place as 0.21-fixes:
[Tue Sep 23 12:12:33 2008] [error] [client 127.0.1.1] File does not exist: /var/www/data/cache, referer: http://media/mythweb/weather

I fixed it by creating a virtual host in apache2 configuration. I guess this is what the developer thought aswell. If the apache2 server was configured for MythWeb alone it would have worked as the /data/cache dir would be in the www-root dir. Assigning MythWeb a virtual host simulates this:

http://mythweb.xxxx.com/

instead of:

http://xxxx.com/mythweb/

Marking incomplete as this release isn't supported anymore. Can anyone confirm that this issue is still present on a supported Mythbuntu/MythTV release?
