Sparkle

an error while downloading the update

Asked by SteveCronin

Folks;

I am using the open source "appcaster" in conjunction with Sparkle.
I know this is a Sparkle forum and my issue could well be with appcaster but maybe not.
And maybe someone here knows enough about appcaster that they could help...
I do not want to be rude, I just need to get over this hump!

My application does correctly detect a new version and then offers the usual 3 option dialog: Later, Skip, Download.
The release notes are correctly shown in the dialog.

If I select the 'Download' option then Sparkle throws an error: 'unsupported URL'
I have the source for Sparkle and its failing at: SUBasicUpdateDriver download:didFail.
The NSURLDownload looks like this: "\appcaster\uploads\myApp_1.0.1.zip"

The .zip file does exist in the uploads directory.

To me it seems as if the NSURLDownload is not fully populated with $WEBROOT, but maybe I'm wrong.
It seems to me that appcaster is generating the downloadURL but I I'm not sure and not sure where in the php that occurs...

Any thoughts really appreciated!
Steve

Can we have a link to your appcast, please?

Andy!

Wow thanks for such a fast response!

From the SUFeedURL in info.plist: http://www.googaby.com/appcaster/appcast.php

Aha! If you look at your enclosures, the URLs provided are partial; Sparkle doesn't know how to handle such relative URLs—what are they relative to? If this is something in the RSS spec that should actually be supported, please file a bug, but I probably won't be able to fix it for a while.

In the meantime, just make your URLs absolute in your feed, and it'll work.

You say "...just make your URLs absolute in your feed, and it'll work..."

How do I do that?

Instead of:

<enclosure url='/appcaster/uploads/googaby_1.0.0.d.zip' length='1786' type='application/octet-stream' />

you should write:

<enclosure url='http://www.googaby.com/appcaster/uploads/googaby_1.0.0.d.zip' length='1786' type='application/octet-stream' />

Given that this was generated by appcaster, though, you should contact the tool's maintainer and report this bug with him.

Andy;

OK so it seems you know enough about appcaster to know that the url is generated by appcaster.
It is NOT a sparkle issue!

That's good information. I've contacted Tyler....

Thanks for the quick responses, the great tool and the continuing contribution to the Mac ecosystem!

Folks;

Forgive this intrusion but Andy was so helpful I thought I'd try to give back in a small way.

For those who might use appcaster the issue is the definition of WEBROOT.
This is found in appcaster/includes/class.configure.php at line 38 (for production servers)

Appcaster is designed to be flexible so my hacking this will break this flexibility but since I am only serving one application from appcaster it works for me.

I just had to make the WEBROOT absolute like Andy had indicated and its working now.
