Do appdata files installed by a package do anything?

[Richard Shaw]

Subject pretty much says it all...

I have an appdata file from upstream that I think has a bad screenshot URL,
how do I test this?

I tried changing the file installed by the package but of course it didn't
do much.

Thanks,
Richard

You can either ask upstream to fix that, or disable that screenshot
for a while(make sure there are still other shots)

Which “that”?  The file (with a different URL) or the bad URL itself (to
make it not bad)?

Any file change would be invisible until the appstream-data package
contents is regenerated, right?  I suspect that's what causes testing
challenges.

'That' should be 'that 404 problem'.

I'm not sure about the policy of modifying the appdata file, should a
package carry file deriving from downstream with correct contents
however or just keep the error.

You can prefer local files over the distro-supplied data using:

killall gnome-software
gnome-software --prefer-local

We prefer the distro-provided data for a few reasons:

* the screenshots come from the mirrors, not upstream
* we replace or add a few things to certain packages
* it takes ages to stat and then load a lot of small files rather than
slurping one large .gz blob.

If you want to override the screenshot, you can either patch the
.appdata.xml in the spec file like any normal file, or you can use the
F22+ command in the spec file:

appstream-util replace-screenshots /path/to/appdata.xml
http://new-screenshot.png

Hope that helps,

Richard.

Thanks, that will at least let me test the change and make sure it works
before I tell upstream.

Well I'm still on F21 until RPM Fusion properly branches but thanks for the
info. In this case the appdata file isn't actually in the source archive
but is provided along side it in their github mirror so I use have it as a
source file.

Thanks,
