Sparkle: Completely broken?

[bdkjones]

Hi guys. I'm pretty sure Sparkle has just stranded tens of thousands of users of my app and I'm a little frustrated.

A couple months ago, I shipped an update to my app that included the then-current version of Sparkle: 1.13.1.

The version of my app was 2.7.1. Today, I shipped an update for version 2.8 and updated my appcast.xml file with the following entry:

<item>
            <title>Version 2.8</title>
            <sparkle:releaseNotesLink>https://incident57.com/codekit/sparkleversionhistory.html</sparkle:releaseNotesLink>
            <pubDate>Friday, 29 April 2016 18:15:00 -0700</pubDate>
            <enclosure url="https://incident57.com/codekit/files/codekit-19120.zip" sparkle:version="19120" sparkle:shortVersionString="2.8" length="52007267" type="application/octet-stream"/>
            <sparkle:minimumSystemVersion>10.8</sparkle:minimumSystemVersion>
        </item>

However, when I check for updates in 2.7.1, Sparkle reports that the latest version of my app that is available is 2.7.1. I have verified that the correct XML file is being downloaded.

What's going on here? And PLEASE tell me I can fix it...

Sparkle is not logging anything to console.app when I check for updates.

This really doesn't look good, guys. I'm incredibly worried that I've now shipped a version of my app that I can never update because Sparkle is silently failing. What can I provide to figure out what's going on?

[bdkjones]

My app is signed with a valid Apple Developer Certificate and as you can see in my item entry above, I'm delivering the download and release notes via https. Additionally, the old version of my app (2.7.1) and the new version both have NSAllowsArbitraryLoads set to YES, which allows using HTTP connections.

Sparkle reports user-friendly version 2.7.1 to the user, but checks against sparkle:version="19120" you've specified. Is that 19120 higher than your CFBundleVersion in the old app?

[bdkjones]

Yes. The old app is 19115.

I'm looking into it

[bdkjones]

If you'd like, the old version (2.7.1) of my app is available at http://incident57.com/codekit/files/codekit-19115.zip

The new version is http://incident57.com/codekit/files/codekit-19120.zip

The location of the appcast.xml file and related resources is in the item entry above. Thanks for the help!

Do you think there's any hope of fixing the problem from where I am, or do I need to start looking at how to contact my customers and let them know they need to manually update to the latest release of my app?

Is the appcast on your server up to date? Going to https://incident57.com/codekit/appcast/ck2appcast.xml , I don't see the entry for 2.8

[bdkjones]

@zorgiepoo What's your physical location in the world? When I visit that URL I get the updated XML with the 2.8 item. That's the very first thing I checked, before I opened this issue. I will re-verify, but I currently don't have any caching enabled on my server so it should not be serving an old version to anyone.

[zorgiepoo]

U.S. EST. It's not serving the new version for me then.

[bdkjones]

@zorgiepoo You're right. When I access the URL through my VPN, I get a different version of the file depending on what location I'm accessing from. There's something funky going on with caching at my hosting provider.

You know, I TRY not look like a moron before I open an issue on GitHub and, invariably, I look like a moron every time I open an issue on GitHub. This really WAS the first thing I checked when the problem appeared. I'll see what the heck is going on with my hosting provider and that will clear this up, I'm sure.

Sorry for the false alarm; just a stressful few hours. In my next life, I will choose literally any other career than software development.
