// Page for downloading the BOINC client, with support for autoattach:
// https://github.com/BOINC/boinc/wiki/SimpleAttach
// Note: to use autoattach:
// 1) You need to have the latest client versions file
//      run html/ops/get_versions.php
// 2) Put your project ID (ask DPA if you don't have one)
//      in config.xml as <project_id>x</project_id>
//
// There's a logged-in user.
//
// Autoattach case: if project has an ID and client is Win or Mac:
//    - find latest version for that platform
//    - Create a login token.
//    - Show download button(s)
//      The download will be via concierge, using the login token.
// Otherwise:
//    - show link to download page on BOINC web site,
//      and instructions for what to do after that.

// Can also be called as a web RPC;
// see https://github.com/BOINC/boinc/wiki/WebRpc#download
// NOT USED - OK TO REMOVE
//  rpc              this says it's an RPC

			0 ignored issues – show Bug introduced 2021-01-22 09:03 UTC by Report Bug Copy Issue Report Are you sure the assignment to `$user` is correct as `get_logged_in_user()` seems to always return `null`. This check looks for function or method calls that always return null and whose return value is assigned to a variable. class A { function getObject() { return null; } } $a = new A(); $object = $a->getObject(); The method `getObject()` can return nothing but null, so it makes no sense to assign that value to a variable. The reason is most likely that a function or method is imcomplete or has been reduced for debug purposes. Loading history...
