Zabbix 8 support
The main module and the five widgets now load on Zabbix 8 as well — verified
on 8.0.0rc1. Until this release the graph tabs (Technical, Management,
Dependencies, Geo) came up blank there, with no error in the module's own code.
The cause was outside the module. Zabbix 8 defines Array.prototype.xor in its
js/common.js with Object.defineProperty, whose omitted attributes default to
non-writable and non-configurable. Cytoscape builds its collection prototype
on top of Array.prototype and merges its own xor() method onto it with
Object.assign; that write cannot shadow the inherited, now non-writable
property and throws, so Cytoscape aborts at load and window.cytoscape is never
defined. On 7.0 and 7.4 the same line is a plain assignment (writable), so they
were never affected — and stay unaffected here.
A small guard (nt-assign-guard.js) swaps Object.assign for a
defineProperty-fallback variant only while Cytoscape loads, then restores
the original. It engages solely when the broken descriptor is actually present,
so on 7.x it is a true no-op; the Zabbix xor helper is left intact and no
Cytoscape update is needed. A depth counter keeps two widgets on one dashboard
from restoring the original mid-load.
Updating from 5.5.2 — replace the directory, reload with a cache bypass
No new action, no template change, nothing stored is touched. Replace the module
directory, chown, reload php-fpm, then load the topology page once with a cache
bypass — the view now pulls in one new script file, and the topology widget
changed too (same guard, widget version 3.2.1).
Changed
- Zabbix 8: guard
Object.assignso Cytoscape loads, wired into the page view
and the topology widget loader (nt-assign-guard.js). - README and badges now list Zabbix 8 (7.0 LTS / 7.4 / 8.0).
