[wp-hackers] auto_update_plugin trouble with self-hosted plugin

[Janis Elsts]

I'm not sure that this list is the right place to discuss third-party  
libraries, but I'll answer anyway. It looks like you're using an older  
version of my update checker:

Like WordPress itself, this library defaults to checking for updates every  
12 hours. However, it uses a custom cron hook, so maybe it didn't get  
triggered by whatever you did to run cron manually.

You can change how often it checks for updates by passing the check period  
(in hours) to the constructor:

require_once 'classes/plugin-updates/plugin-update-checker.php';
$myPluginUpdateChecker = new PluginUpdateChecker_1_4(
	'http://example.com/myplugin.json',
	__FILE__,
	'myplugin',
	42  //Check every 42 hours.
);

If you want your plugin to have full control over when exactly it checks  
for updates, you can turn off automatic checks by setting this argument to  
0. Then call $myPluginUpdateChecker->checkForUpdates() directly.

You can use the Debug Bar plugin to see the last update check time, when  
the next automatic check will happen, and other useful information. It'll  
show up in the "PUC (your-plugin-slug)" panel.

Most of the above described in the documentation:
