Admin-scoped users (answers: who can create a 'user' account, only super or
also an admin within their own scope?):
- New owner_admin_id column on users (migration 004). NULL means created by
super (company-wide, previous behavior); otherwise scoped to that admin's
own codes.
- Users::addUser/editUser/deleteUser now allow an 'admin' session, but force
type='user' and owner_admin_id to their own id regardless of submitted
input. user.php/users.php open up to admins with a restricted UI (no type
picker, listing limited to their own created users).
- New qr_compute_scope_owner_id()/qr_apply_owner_scope()/qr_has_full_visibility()
helpers in includes/security.php, replacing the ad-hoc type==='admin' checks
in index.php, dynamic_qrcodes.php, static_qrcodes.php and bulk_action.php.
A 'user' account created by an admin is now scoped to that admin's codes
instead of seeing everything company-wide.
Qr code storage hardening: images were served as plain static files under the
document root with no auth check at all. Storage now lives outside the web
root; qrcode_image.php and qrcode_zip_download.php gate access with the same
permission model as the list pages, and the bulk zip download is bound to the
session that generated it.
PHP 8.4 + chillerlan/php-qrcode 6.0.1: bumped since this is a dockerized app,
so the PHP version shipped doesn't matter to end users. Note: the 6.0.1 tag
itself only requires PHP 8.2 - the earlier "needs 8.4" read was from an
unpinned clone of master, which has since moved past the tag. Fixed along the
way, surfaced by testing on 8.4:
- The hardcoded Imagick build (an old pinned master commit, workaround for
3.7.0 being broken on PHP 8.3+) no longer compiles on 8.4. Imagick 3.8.1 is
now a normal stable release, so the workaround is gone.
- config.php had display_errors=On + error_reporting(E_ALL), so PHP 8.4's new
deprecation notices got dumped straight into the response before
session_start() could run, breaking login outright. Also an info-disclosure
risk on its own. Now logged instead of displayed.
- MysqliDb::insertMulti() had an implicit nullable parameter, now explicit.
- includes/auth_validate.php redirected unauthenticated requests but never
called exit(), so the rest of the script kept running.
- Dockerfile.fpm was missing both git (needed to clone chillerlan/php-qrcode)
and the imagick extension entirely.
Also removes the unused sample qr code images that shipped in the original
repo; storage now lives outside the document root so they were never going
to be served again.
