If all media is invalid and only 1 layout exists Xibo will crash

[Dan Garner]

The most likely scenario for this to happen would be for the cachemanager.xml file to be corrupted.

[Dan Garner (dangarner)]

I think the only solution is for the:
- cachemanager to be aware of layouts and their content
- schedulemanager to be aware of the cachemanager

In this way the active schedule could contain only layouts that have at least 1 valid piece of media.

I did some testing on what I think is the same issue, here's what happens with my dotnet client: if you create a layout where the first region is empty (as in the first one of the xlf file) and this is the only layout, the player will always crash, regardless of the other regions content. If I delete the first region, the next one will become the first and the same problem will occur.
If there are 2 layouts in the schedule, the player doesn't crash but the content of the 'buggy' layout gets merged (literally) under the second layout. A 3rd layout and presumably others don't get affected and display normally.

Thanks Rui

Can you try the same tests with the 1.2.1 pre-release?

Just tried the pre-release but exactly the same problem occurs. I always clear the 'Media Library' directory and the xlf files are OK.

Thanks!

You need to clear the cacheManager.xml file too otherwise it will crash for sure (as it assumes that once a file has been downloaded it will remain there).

In fact if you could take a copy of your cacheManager.xml file before moving/renaming it that would be great as it may be useful to Dan - I'm not sure.

No change. With a single layout (when it crashes), 'cachemanager.xml' simply contains:

--- BEGIN
<?xml version="1.0" encoding="utf-8"?>
<CacheManager xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <_files />
</CacheManager>
--- END

Thanks

Additional patch for this:

On the server side, in "lib/service/xmdssoap.class.php" on line 203 - change

    $SQL .= " ORDER BY RecordType";

to

    $SQL .= " ORDER BY RecordType DESC";
