Opt-in per product via WHMCS's native tblproducts.stockcontrol toggle.
When enabled, the module overwrites tblproducts.qty with the number of
VPSes the panel can still actually provision, derived from two
authoritative sources:
- GET /packages/{id} for the per-VPS resource footprint (memory,
cpuCores, primaryStorage, primaryStorageProfile, enabled)
- GET /compute/hypervisors/groups/{id}/resources for live
free/allocated data per hypervisor in the group
Algorithm sums min(memory, cpu, storage) across eligible hypervisors
(enabled AND commissioned AND !prohibit) for every group the product
can be placed in (default configoption1 plus every numeric value of a
Location configurable option), capped by the group-level IPv4 pool
taken as max() within a group to avoid double-counting. Storage
matching is strict against package.primaryStorageProfile; hypervisors
without the named pool contribute 0.
FAIL-SAFE INVARIANT: transient API failures return null from
Module::fetchPackage / Module::fetchGroupResources, and the orchestrator
leaves tblproducts.qty UNCHANGED in that case. Confirmed-missing
conditions (HTTP 404, package.enabled=false) return qty=0. Without this
tri-state contract the module would either zero out inventory during
API blips, or show inventory for packages that have been deleted.
Triggers:
- AfterModuleCreate: refresh + auto-accept pending order
- AfterModuleTerminate: refresh (capacity came back)
- AfterCronJob: every-2-hour safety net for out-of-band panel changes
- ClientAreaPageCart: opportunistic per-product refresh in order flow
- admin.php?action=stockRecalculate: on-demand full recalc
Shared 30s rate-limit (stockrefresh:event) coalesces provision bursts;
60s per-product limit (stockrefresh:{pid}) caps cart-page refreshes;
grpres:{id} 120s TTL caps upstream API reads per group regardless of
how often hooks fire.
Auto-accept: AfterModuleCreate calls WHMCS AcceptOrder with
autosetup=false when the parent order is still Pending. Idempotent;
already-accepted orders are skipped via strcasecmp status check.
New per-product config option stockSafetyBufferPct (configoption7,
default 10) reserves X% of each resource's max before computing fits.
Blank falls back to 10% so existing products get headroom without any
config change. Ignored for unlimited resources (max=0) and for IPv4
(no per-hypervisor max in the response).
TestConnection now probes /compute/hypervisors/groups to surface
missing compute:read scope at config time instead of as unexplained
nightly silence.
Introduces an opt-in reverse DNS management subsystem backed by a PowerDNS
Authoritative HTTP API. Runs via a companion WHMCS addon module
(modules/addons/VirtFusionDns) that holds settings and a Test Connection
page; the server module reads those settings from tbladdonmodules and
short-circuits when the addon is absent or disabled, so provisioning is
unaffected for operators who don't use the feature.
Lifecycle hooks:
- createAccount creates PTRs for every assigned IP (forward DNS must
already resolve to the IP — FCrDNS enforcement)
- renameServer updates only PTRs whose content matched the old hostname,
preserving client-custom records
- terminateAccount deletes all PTRs before the local state is purged
- TestConnection merges PowerDNS health check with the existing VirtFusion
check
- A DailyCronJob hook reconciles missing PTRs additive-only (never
overwrites)
Client UI: new "Reverse DNS" panel on the service overview with one
editable PTR input per assigned IP, per-row status badges, and
forward-DNS rejection on save. Admin services tab gets a parallel
widget with Reconcile (additive) and Reconcile (force reset) buttons.
New subsystem at lib/PowerDns/:
- Client.php PowerDNS API wrapper (X-API-Key, listZones/getZone/
patchRRset/notifyZone), auto-NOTIFY on successful PATCH
- Config.php Loads + decrypts addon settings from tbladdonmodules
- IpUtil.php PTR-name generation (IPv4 + IPv6), zone matching,
RFC 2317 classless parsing
- Resolver.php FCrDNS verification via dns_get_record with CNAME-chain
following and per-(hostname,ip) caching
- PtrManager.php Orchestrator: syncServer, deleteForServer, listPtrs,
setPtr, reconcile, reconcileAll
Security hardening helpers added to Module and applied to the rDNS
endpoints:
- requirePost() HTTP method gate (405 on non-POST mutations)
- requireSameOrigin() Origin/Referer check against WHMCS host (CSRF
defence against cross-site form POST)
- requireServiceStatus() tblhosting.domainstatus filter (Active for
writes, Active+Suspended for reads)
RFC 2317 classless delegations (e.g. 64/64.113.0.203.in-addr.arpa.)
supported with alignment validation: rejects misaligned start addresses
that don't correspond to any real delegation boundary.
PowerDNS zone IDs containing '/' are URL-encoded as '=2F' per the
PowerDNS API convention. PATCH success triggers PUT /zones/{id}/notify
so slaves pick up the SOA-bumped serial immediately.
Includes IPv4 + IPv6 support, per-IP write rate limit (10s), fresh
IP-ownership re-verification on every client write (defends against
stale-ownership after IP reassignment), and audit logging of every
successful edit to the WHMCS module log.

- Auto-create 'Initial Operating System' and 'Initial SSH Key' custom fields
via Database::ensureCustomFields() on module load, eliminating the manual
modify.sql step

- Add try/catch blocks around every DB operation and API call across all PHP
files per CLAUDE.md error handling rules
- Add comprehensive PHPDoc to all classes, methods, and properties

code formatting across the codebase
- Add git pre-commit hook (hooks/pre-commit) that runs Pint on staged PHP
files, auto-installed via Composer post-install/post-update scripts
- Simplify README installation to a single copy-paste command
