BerlinDB Atomic Counter hamwe na increment_item()

Ultimate Multisite v2.6.1 yongeyemo uburyo bwa increment_item() muri class ya BerlinDB Query. Buyikoreshe mu gukora kongera imibare mu nkingi z’imibare mu buryo butekanye kandi bwa atomic, nta masiganwa ya read-modify-write — bifite akamaro kuri counters, usage quotas, na rate-limiting checks zikora mu gihe hari requests nyinshi icyarimwe.

Umukono w’uburyo

/**
 * Atomically increment a numeric column for a specific item.
 *
 * @param int    $item_id   Primary key of the row to update.
 * @param string $column    Column name to increment (must be numeric).
 * @param int    $amount    Amount to add. Use a negative value to decrement.
 *                          Defaults to 1.
 * @return bool True on success, false on failure or if the column is invalid.
 */
public function increment_item( int $item_id, string $column, int $amount = 1 ): bool;

Imikoreshereze y’ibanze

// Add 1 to the `api_calls` column for membership ID 42.
$memberships = new WP_Ultimo\Database\Memberships\Memberships_Query();
$memberships->increment_item( 42, 'api_calls' );

// Add 5 to a usage counter.
$memberships->increment_item( 42, 'api_calls', 5 );

// Decrement (subtract 1).
$memberships->increment_item( 42, 'api_calls', -1 );

Gukurikirana imikoreshereze ya API kuri membership

Uburyo ngiro bwo gushyiraho imipaka ya API rate limits kuri buri membership:

class Membership_API_Limiter {

    /** Maximum API calls allowed per billing cycle. */
    const LIMIT = 500;

    public function __construct() {

    }

    /**
     * Reject the request if the membership is over the limit;
     * otherwise count the call atomically.
     *
     * @param bool   $enabled
     * @param object $context  Object with a get_membership_id() method.
     * @return bool
     */
    public function check_and_count( bool $enabled, $context ): bool {
        if ( ! $enabled ) {

        $memberships = new WP_Ultimo\Database\Memberships\Memberships_Query();
        $membership  = $memberships->get_item( $membership_id );

        if ( ! $membership ) {
            return false;
        }

        if ( (int) $membership->api_calls >= self::LIMIT ) {
            return false;  // Over quota — reject.
        }

        // Atomic increment: safe under concurrent requests.
        $memberships->increment_item( $membership_id, 'api_calls' );

        return true;
    }
}

new Membership_API_Limiter();

Impamvu ukoresha increment_item() aho gukoresha update_item()

Uburyo busanzwe bwa read-modify-write ntabwo butekanye mu gihe hari requests nyinshi icyarimwe:

// UNSAFE — race condition between read and write.
$membership = $memberships->get_item( $membership_id );
$new_count  = (int) $membership->api_calls + 1;
$memberships->update_item( $membership_id, [ 'api_calls' => $new_count ] );

Requests ebyiri zibereye icyarimwe zishobora gusoma agaciro kamwe, zombi zigashyiramo igisubizo kimwe cyongeweho, bigatuma count imwe itakara. increment_item() iha database engine inshingano zo gukora imibare ikoresheje interuro imwe ya UPDATE ... SET column = column + ?, bigatuma icyo gikorwa kiba atomic muri kamere yacyo.
