websites/Gitlab-Issue-Listing-Script#19: Only public projects are being listed despite public_projects_only being disabled

It wasn't actually public projects that were being listed, it just wasn't all that should have been.

There were exactly 40 pages being displayed, when there should (based on the fix) have been 72.

Gitlab returns results in a paginated format, you have to look for a next header to get the next page. The code handles that quietly in the background.

However, it seems that once in a while, Gitlab includes an extra leading space in that header value - this was being passed into PHP's CuRL which was silently refusing to connect out to an invalid URL.

I turned error_reporting and display_errors on and got absolutely nothing.

In this snippet

        curl_setopt($this->curl, CURLOPT_URL, $url);
        curl_setopt($this->curl, CURLOPT_RETURNTRANSFER, 1);

        curl_setopt($this->curl, CURLOPT_HEADERFUNCTION,
        function($curl, $header) use (&$headers)
        {
            $len = strlen($header);
            $header = explode(':', $header, 2);
            if (count($header) < 2) // ignore invalid headers
            return $len;

            $headers[strtolower(trim($header[0]))][] = trim($header[1]);

            return $len;
        }
        );


        $result = curl_exec($this->curl);

        $links = array();
        if (array_key_exists("link", $headers)){
            $links = GILSUtils::parseLinkHeader($headers['link'][0]);
        }
        return array("result" => $result, "headers" => $headers, "links" => $links);

The arrays were ending up completely empty. I dropped an echo curl_error($this->curl) in there but still nothing.

Ultimately the fix in commit c88fa2a3c was to add a trim

$url = trim($url)

to ensure any leading or trailing gumph is removed
