Function plugins_api is not triggered for non wp-marketplace plugins

[marthm]

I currently try to setup a private-hosted repository for my own plugins / themes and tried to do that with the filter hooks in the plugin-install.php file - the documentation of it indicates that this should be possible, even on the latest version (5.2.2).

I activated my own plugin on my bedrock (​https://roots.io/bedrock/) setup and following the tutorial ​https://rudrastyh.com/wordpress/self-hosted-plugin-update.html#comments i tried to implement the update mechanism.

I think while doing that i stumbled upon a bug that causes wordpress to not trigger the plugins_api method at all - i can hook into the "site_transient_update_plugins" filter to display the update-badge next to the plugins navbar item but the update text / button and show-details button for my plugins wont show up.

Thank you for the bug report, @marthm!

Could you please add step-by-step instructions, with sample code, to reproduce this issue?

Thank you for the bug report, @marthm!

Could you please add step-by-step instructions, with sample code, to reproduce this issue?

As noted in my bug report i use this tutorial and i copied all the code with some minor changes. Here's the code that i use:

<?php

}

add_filter('plugins_api_result', 'smh_test_pluginSlug', 20, 3);
add_filter('plugins_api', 'smh_test_pluginSlug', 20, 3);

With the json file being:

{
    "name" : "Test-Plugin",
    "slug" : "pluginSlug",
    "download_url" : "https://someWebsite/marthm/WordPressRepo/test/update.zip",
    "version" : "1.1",
    "requires" : "3.0",
    "tested" : "4.8.1",
    "last_updated" : "2019-07-17 11:00:00",
        "upgrade_notice" : "Ein Plugin-Update ist verfügbar.",
        "author" : "marthm",
        "author_homepage" : "https://www.example.com",
        "sections" : {
                "description" : "This is the plugin to test your updater script",
                "installation" : "Upload the plugin to your blog, Activate it, that's it!",
                "changelog" : "<h4>1.1 –  August 17, 2017</h4><ul><li>Some bugs are fixed.</li><li>Release date.</li></ul>"
        }
}

I tried to echo out something to test if the function gets called at all, but i can't find that "test" in the html of the plugin-list page at all ;-;

The server i try to call in the function doesn't have a valid ssl-certificate as for why i deactivate the sslverify.
The zip-file that's mentioned in the .json file (update.zip) doesn't exist as of now, but that shouldn't be a problem, right? o:

I tried to fix something with adding that other "plugins_api_result" filter, but that doesn't seem to work either ;-;

What should happen after the plugin gets activated:
There should be a "view details" button next to the author link that displays the information from the json in a modal.

What happens instead:
Nothing :c

I hope this helps :)
