AssetVariantRegeneratePresenter extends BasePresenter
in package

FinalYes

Regenerates missing variants of stored images, for all usages at once.

Same as the "regenerate" button on the Usage tab. It first fills usage_key of old images from their path, then processes at most limit images per usage (default AssetVariantRegenerationManager::DEFAULT_BATCH). It never overwrites existing files and skips video and SVG; an image whose regeneration fails three times is skipped. The lock is shared with the admin button, so batches never run concurrently.

Overwriting existing files is not supported by the cron, because it would run over all usages at once; it stays a deliberate admin action on a single usage.

URL: /cron/system/asset-variant-regenerate?token=xxx[&limit=25]

Frequency: repeatedly after deployment until the response says remaining: 0; then daily at night is enough (it regenerates only what is missing again after a plan or usage change).

Properties

$operationRunner

Boundary of one cron action (see {@see self::tryCall()}).

public OperationRunner $operationRunner
Attributes
#[Inject]

Methods

releaseLock()

Releases the lock at most once; called by both `shutdown()` and the PHP shutdown function.

public releaseLock() : void

sendResponse()

public sendResponse(Response $response) : void
Parameters
$response : Response

setConfigParameters()

public setConfigParameters([bool $debugMode = false ][, bool $productionMode = false ]) : void
Parameters
$debugMode : bool = false
$productionMode : bool = false

shutdown()

public shutdown(Response $response) : void
Parameters
$response : Response

isSameSiteRequest()

Tells whether the request comes from the own site (Nette SameSite cookie); protects GET actions with a side effect.

protected isSameSiteRequest() : bool

getHttpRequest() returns the IRequest interface, while isSameSite() exists only on Nette\Http\Request.

Return values
bool

sendError()

protected sendError(string $message[, int $code = 500 ]) : never
Parameters
$message : string
$code : int = 500
Return values
never

sendSkipped()

Reports that the job did only part of the work and the next call finishes the rest (e.g. a reindex done in chunks).

protected sendSkipped(string $reason[, array<string, mixed> $data = [] ]) : never

The scheduler does not record skipped as a run, so the job stays due and is called again on the next tick.

Parameters
$reason : string
$data : array<string, mixed> = []
Return values
never

sendSuccess()

protected sendSuccess([array<string|int, mixed> $data = [] ]) : never
Parameters
$data : array<string|int, mixed> = []
Return values
never

tryCall()

Runs the `action<Action>()` method as one operation (transitional).

protected tryCall(string $method, array<string, mixed> $params) : bool

Cron has no internalAction*(): its actions call the Api managers directly, so without this in scoped mode nothing would ever empty the unit of work of a cron run. The boundary is the action only; startup() (settings, token, lock) stays outside like the startup of an Api request. A cron action ends with AbortException from send*(), which is a regular end: the outcome comes from the response (ok succeeded, skipped unknown — possibly a part of a batch was done, error failed). Render and signal methods are not wrapped (cron presenters have none).

Parameters
$method : string
$params : array<string, mixed>
Return values
bool
