    定義済み定数

    以下の定数が定義されています。 この関数の拡張モジュールが PHP 組み込みでコンパイルされているか、 実行時に動的にロードされている場合のみ使用可能です。

    Return values. Always check GearmanClient::error() or GearmanWorker() for a string error, as it may contain more details:

    GEARMAN_SUCCESS (int)
    Whatever action was taken was successful.
    GEARMAN_IO_WAIT (int)
    When in non-blocking mode, an event is hit that would have blocked.
    GEARMAN_ERRNO (int)
    A system error. Check GearmanClient::errno() or GearmanWorker::errno() for the system error code that was returned.
    GEARMAN_NO_ACTIVE_FDS (int)
    GearmanClient::wait() or GearmanWorker() was called with no connections.
    GEARMAN_UNEXPECTED_PACKET (int)
    Indicates something going very wrong in gearmand. Applies only to GearmanWorker.
    GEARMAN_GETADDRINFO (int)
    DNS resolution failed (invalid host, port, etc).
    GEARMAN_NO_SERVERS (int)
    Did not call GearmanClient::addServer() before submitting jobs or tasks.
    GEARMAN_LOST_CONNECTION (int)
    Lost a connection during a request.
    GEARMAN_MEMORY_ALLOCATION_FAILURE (int)
    Memory allocation failed (ran out of memory).
    GEARMAN_SERVER_ERROR (int)
    Something went wrong in the Gearman server and it could not handle the request gracefully.
    GEARMAN_WORK_DATA (int)
    Notice return code obtained with GearmanClient::returnCode() when using GearmanClient::do(). Sent to update the client with data from a running job. A worker uses this when it needs to send updates, send partial results, or flush data during long running jobs.
    GEARMAN_WORK_WARNING (int)
    Notice return code obtained with GearmanClient::returnCode() when using GearmanClient::do(). Updates the client with a warning. The behavior is just like GEARMAN_WORK_DATA, but should be treated as a warning instead of normal response data.
    GEARMAN_WORK_STATUS (int)
    Notice return code obtained with GearmanClient::returnCode() when using GearmanClient::do(). Sent to update the status of a long running job. Use GearmanClient::doStatus() to obtain the percentage complete of the task.
    GEARMAN_WORK_EXCEPTION (int)
    Notice return code obtained with GearmanClient::returnCode() when using GearmanClient::do(). Indicates that a job failed with a given exception.
    GEARMAN_WORK_FAIL (int)
    Notice return code obtained with GearmanClient::returnCode() when using GearmanClient::do(). Indicates that the job failed.
    GEARMAN_COULD_NOT_CONNECT (int)
    Failed to connect to servers.
    GEARMAN_INVALID_FUNCTION_NAME (int)
    Trying to register a function name of NULL or using the callback interface without specifying callbacks.
    GEARMAN_INVALID_WORKER_FUNCTION (int)
    Trying to register a function with a NULL callback function.
    GEARMAN_NO_REGISTERED_FUNCTIONS (int)
    When a worker gets a job for a function it did not register.
    GEARMAN_NO_JOBS (int)
    For a non-blocking worker, when GearmanWorker::work() does not have any active jobs.
    GEARMAN_ECHO_DATA_CORRUPTION (int)
    After GearmanClient::echo() or GearmanWorker::echo() the data returned doesn't match the data sent.
    GEARMAN_NEED_WORKLOAD_FN (int)
    When the client opted to stream the workload of a task, but did not specify a workload callback function.
    GEARMAN_PAUSE (int)
    For the non-blocking client task interface, can be returned from the task callback to "pause" the call and return from GearmanClient::runTasks(). Call GearmanClient::runTasks() again to continue.
    GEARMAN_UNKNOWN_STATE (int)
    Internal client/worker state error.
    GEARMAN_SEND_BUFFER_TOO_SMALL (int)
    Internal error: trying to flush more data in one atomic chunk than is possible due to hard-coded buffer sizes.
    GEARMAN_TIMEOUT (int)
    Hit the timeout limit set by the client/worker.

    GearmanClient options:

    GEARMAN_CLIENT_GENERATE_UNIQUE (int)
    Generate a unique id (UUID) for each task.
    GEARMAN_CLIENT_NON_BLOCKING (int)
    Run the cient in a non-blocking mode.
    GEARMAN_CLIENT_UNBUFFERED_RESULT (int)
    Allow the client to read data in chunks rather than have the library buffer the entire data result and pass that back.
    GEARMAN_CLIENT_FREE_TASKS (int)
    Automatically free task objects once they are complete. This is the default setting in this extension to prevent memory leaks.

    GearmanWorker options:

    GEARMAN_WORKER_NON_BLOCKING (int)
    Run the worker in non-blocking mode.
    GEARMAN_WORKER_GRAB_UNIQ (int)
    Return the client assigned unique ID in addition to the job handle.

    Base Gearman configuration:

    GEARMAN_DEFAULT_TCP_HOST (string)
    GEARMAN_DEFAULT_TCP_PORT (int)
    GEARMAN_DEFAULT_SOCKET_TIMEOUT
