feat: opt-in Nominatim geocoding observer + sync UUID migrations
Adds an AddressObserver that resolves latitude/longitude from the
postal fields after every save, serializing calls cluster-wide through
a Cache::lock and respecting Nominatim's 1-req/sec usage policy.
How the rate limit holds across workers
---------------------------------------
* Cache::lock('addresses:geocoding:lock') ensures only ONE process
ever talks upstream at a time (any LockProvider-capable store works:
redis / memcached / database / file / array).
* Inside the lock the driver reads a shared :last_call_at timestamp
and usleep()s the difference to the configured min_interval before
hitting the API, then stamps the new value right after the response
comes back — pacing the next caller from when we *actually stopped*
talking upstream, not from when the lock was first taken.
* Lock TTL (15s default) bounds crash-recovery time so a kill -9
can't pin the lock open forever.
Observer behaviour
------------------
* Hooks 'created' (always geocodes on insert) and 'updated' (only when
a *postal* field actually changed — wasChanged() on street, city,
postal_code, country_code, …). Lat/lon edits don't loop because
the write-back uses saveQuietly().
* Errors (LockTimeoutException, network, 5xx) are logged and
swallowed — the user's save() / create() call is never made fatal
by a transient upstream issue.
* Honours an update_only_when_missing toggle so apps can preserve
manually-entered coordinates.
Backward compatibility
----------------------
* Default 'enabled' is FALSE — upgrading the package does NOT start
making outbound HTTP calls on existing apps. Apps that want the
feature opt in via ADDRESSES_GEOCODING_ENABLED=true and a
descriptive ADDRESSES_GEOCODING_USER_AGENT (OSMF blocks generic UAs).
* The Geocoder contract is bound through the container so apps can
rebind to Google Maps / Mapbox / a self-hosted Nominatim without
touching the observer.
Pre-existing fix shipped alongside
----------------------------------
The Address* models switched to HasUuids in 73c14c5, but neither the
published migration stub nor the workbench fixture migration were
updated — every test in the suite was failing with 'datatype mismatch'
on the auto-increment integer PK. Both migrations now use uuid('id')
+ foreignUuid() so the model trait and the schema agree.
For consumers who already published the stub: no change. Your
existing migration file is untouched. Only fresh `vendor:publish
--tag=addresses-migrations` runs pick up the UUID shape.

Tests
-----
221 / 221 (100%) Time: ~2.8s
The 14 new tests cover URL/param construction, User-Agent, empty- and
unparseable-result handling, the rate-limit timing assertion (proves
two back-to-back calls take >= min_interval), cache-lock
serialization, observer pre-fill on create, no-loop on lat/lon
update, re-geocode on postal change, the update_only_when_missing
policy, the enabled master switch, and graceful swallowing of both
LockTimeoutException and generic upstream errors.

### 5. Automatic geocoding (opt-in)
|
||||
|
||||
Set `ADDRESSES_GEOCODING_ENABLED=true` to have an observer ask Nominatim
|
||||
(OpenStreetMap) for `latitude` / `longitude` after every save. Calls are
|
||||
serialized cluster-wide through a `Cache::lock` and paced at 1 req/sec
|
||||
to honour the OSMF usage policy. **Off by default** so an upgrade
|
||||
doesn't surprise existing apps with new outbound HTTP traffic.
|
||||
|
||||
```ini
|
||||
# .env
|
||||
ADDRESSES_GEOCODING_ENABLED=true
|
||||
# OSMF policy: identify your app — generic UAs get blocked.
|
||||
ADDRESSES_GEOCODING_USER_AGENT="my-app (https://example.com)"
|
||||
ADDRESSES_GEOCODING_EMAIL="ops@example.com"
|
||||
```
|
||||
|
||||
```php
|
||||
$address = Address::create([
|
||||
'street' => 'Stephansplatz 1',
|
||||
'postal_code' => '1010',
|
||||
'city' => 'Vienna',
|
||||
'country_code' => 'AT',
|
||||
]);
|
||||
|
||||
// Observer has filled these in by the time create() returns.
|
||||
$address->refresh();
|
||||
$address->latitude; // 48.2082…
|
||||
$address->longitude; // 16.3738…
|
||||
```
|
||||
|
||||
Tunable knobs (see [`config/addresses.php`](config/addresses.php) →
|
||||
`geocoding`):
|
||||
|
||||
- `enabled` — master switch (env: `ADDRESSES_GEOCODING_ENABLED`)
|
||||
- `driver` — only `nominatim` ships out of the box, but you can rebind
|
||||
the `Geocoder` contract to plug in Google Maps / Mapbox / Mapquest /
|
||||
a self-hosted Nominatim
|
||||
- `update_only_when_missing` — leave manually-entered coordinates alone
|
||||
- `min_interval_seconds` — global ceiling on outbound traffic (default
|
||||
`1.0`, matches Nominatim's published policy)
|
||||
- `lock_wait_seconds`, `lock_ttl_seconds` — Cache lock parameters
|
||||
- `accept_language` — Nominatim's `display_name` localization
|
||||
- `drivers.nominatim.user_agent` / `email` — required by Nominatim for
|
||||
attribution; set both in production
|
||||
|
||||
For tests / imports, disable per-environment with
|
||||
`ADDRESSES_GEOCODING_ENABLED=false` (or

`config()->set('addresses.geocoding.enabled', false)` inside a TestCase

# Auto-Geocoding
|
||||
|
||||
After every `Address` save, an observer asks a geocoding service for
|
||||
`latitude` / `longitude` based on the postal fields, then writes the
|
||||
result back onto the row.
|
||||
|
||||
The default driver is **Nominatim (OpenStreetMap)** — free, no API key
|
||||
required, but [policy-capped](https://operations.osmfoundation.org/policies/nominatim/)
|
||||
at **1 request per second** on the public instance. The package
|
||||
enforces that cap with a Laravel `Cache::lock`, so even multiple PHP-FPM
|
||||
workers / queue runners sharing the same address book never overshoot.
|
||||
|
||||
> **Opt-in.** The observer is wired up but the master switch defaults to
|
||||
> `false`, so upgrading the package doesn't change behaviour for an
|
||||
> existing app. Set `ADDRESSES_GEOCODING_ENABLED=true` (and a
|
||||
> descriptive `ADDRESSES_GEOCODING_USER_AGENT`) to turn it on.
|
||||
|
||||
## Lifecycle
|
||||
|
||||
```
|
||||
Address::create([...])
|
||||
│
|
||||
├─► INSERT row
|
||||
│
|
||||
├─► AddressObserver::created
|
||||
│ │
|
||||
│ ├─► Cache::lock acquired (cluster-wide)
|
||||
│ ├─► sleep until min_interval since last call
|
||||
│ ├─► HTTP GET nominatim/search?…
|
||||
│ ├─► stamp "last call at" → cache
|
||||
│ └─► lock released
|
||||
│
|
||||
├─► $address->saveQuietly() (lat / lon → DB, no recursion)
|
||||
│
|
||||
└─► return $address
|
||||
```
|
||||
|
||||
Updates work the same way, but the observer only fires the geocoder
|
||||
when a **postal** field actually changed (street, postal_code, city,
|
||||
state, county, country_code, building, street_extra). Plain
|
||||
latitude/longitude edits — including the observer's own write-back —
|
||||
don't loop, and unrelated columns (notes, meta, has_elevator, …) are
|
||||
ignored.
|
||||
|
||||
## Configuration
|
||||
|
||||
```php
|
||||
// config/addresses.php
|
||||
'geocoding' => [
|
||||
'enabled' => true, // master switch
|
||||
'driver' => 'nominatim', // only one shipped
|
||||
'update_only_when_missing' => false, // keep manual coords
|
||||
'cache_store' => null, // default cache store
|
||||
'cache_prefix' => 'addresses:geocoding',
|
||||
'lock_wait_seconds' => 10, // queue depth budget
|
||||
'lock_ttl_seconds' => 15, // crash-recovery TTL
|
||||
'min_interval_seconds' => 1.0, // OSMF policy floor
|
||||
'timeout_seconds' => 8,
|
||||
'accept_language' => 'en',
|
||||
'drivers' => [
|
||||
'nominatim' => [
|
||||
'endpoint' => 'https://nominatim.openstreetmap.org/search',
|
||||
'user_agent' => 'your-app-name (you@example.com)',
|
||||
'email' => 'you@example.com',
|
||||
],
|
||||
],
|
||||
],
|
||||
```
|
||||
|
||||
Every key reads from a matching `env('ADDRESSES_GEOCODING_*')` so you
|
||||
can override per-environment without publishing the config.
|
||||
|
||||
### Notable env vars
|
||||
|
||||
| Variable | Default | Use case |
|
||||
|----------------------------------------------|-------------------------|----------------------------------------------------|
|
||||
| `ADDRESSES_GEOCODING_ENABLED` | `true` | Turn the whole observer off (CI, bulk imports) |
|
||||
| `ADDRESSES_GEOCODING_ONLY_WHEN_MISSING` | `false` | Preserve manually-entered coordinates |
|
||||
| `ADDRESSES_GEOCODING_MIN_INTERVAL` | `1.0` | Lower than 1 only if you self-host Nominatim |
|
||||
| `ADDRESSES_GEOCODING_USER_AGENT` | package default | **Set in production** — OSMF blocks generic UAs |
|
||||
| `ADDRESSES_GEOCODING_EMAIL` | `null` | Contact email for OSMF (recommended) |
|
||||
| `ADDRESSES_GEOCODING_NOMINATIM_URL` | OSM public endpoint | Point at a self-hosted Nominatim instance |
|
||||
| `ADDRESSES_GEOCODING_CACHE_STORE` | app default | Share the lock across processes (redis / memcache) |
|
||||
|
||||
## Plug in a different provider
|
||||
|
||||
The observer talks to the `Geocoder` contract, not to any concrete
|
||||
driver. Bind your own implementation in a service provider:
|
||||
|
||||
```php
|
||||
use Blax\Addresses\Services\Geocoding\Contracts\Geocoder;
|
||||
use App\Services\MyMapboxGeocoder;
|
||||
|
||||
public function register(): void
|
||||
{
|
||||
$this->app->singleton(Geocoder::class, MyMapboxGeocoder::class);
|
||||
}
|
||||
```
|
||||
|
||||
The contract is:
|
||||
|
||||
```php
|
||||
interface Geocoder
|
||||
{
|
||||
public function geocode(Address $address): ?GeocodingResult;
|
||||
}
|
||||
```
|
||||
|
||||
`GeocodingResult` is a small DTO with `latitude`, `longitude`,
|
||||
`displayName`, and the raw provider payload.
|
||||
|
||||
Your driver is responsible for its own concurrency / rate-limit policy
|
||||
— Google Maps and Mapbox have quota systems server-side, so a custom
|
||||
driver usually doesn't need a `Cache::lock` at all.
|
||||
|
||||
## Failure modes
|
||||
|
||||
The observer is forgiving by design — geocoding is best-effort:
|
||||
|
||||
| Failure | Behaviour |
|
||||
|-------------------------------|----------------------------------------------------------------------------------------------------|
|
||||
| `Cache::lock` wait times out | Logged (`info`), the address keeps its current coords. Re-save (or backfill) to retry. |
|
||||
| Network / 5xx from upstream | Logged (`warning`), the address keeps its current coords. |
|
||||
| Upstream returns no match | Silent — no logs, no DB writes. |
|
||||
| Upstream returns garbage | Silent — invalid lat/lon (`NaN`, missing, non-numeric) are treated as "no match". |
|
||||
|
||||
In every case the user's `save()` / `create()` call returns
|
||||
successfully — geocoding never blows up the consuming code path.
|
||||
|
||||
## Testing
|
||||
|
||||
Drop `Http::fake()` into your test setup; the geocoder uses Laravel's
|
||||
HTTP client so it picks up the fakes automatically. To turn the
|
||||
observer off entirely:
|
||||
|
||||
```php
|
||||
protected function defineEnvironment($app): void
|
||||
{
|
||||
$app['config']->set('addresses.geocoding.enabled', false);
|
||||
}
|
||||
```
|
||||
|
||||
See `tests/Unit/GeocodingTest.php` for full examples including the
|
||||
rate-limit timing assertion.
