S"\Rh 5 r5 " S# S$\55 r6 " S% S&\55 r7g)'aC Speeds up S3 throughput by using processes Getting Started =============== The :class:`ProcessPoolDownloader` can be used to download a single file by calling :meth:`ProcessPoolDownloader.download_file`: .. code:: python from s3transfer.processpool import ProcessPoolDownloader with ProcessPoolDownloader() as downloader: downloader.download_file('mybucket', 'mykey', 'myfile') This snippet downloads the S3 object located in the bucket ``mybucket`` at the key ``mykey`` to the local file ``myfile``. Any errors encountered during the transfer are not propagated. To determine if a transfer succeeded or failed, use the `Futures`_ interface. The :class:`ProcessPoolDownloader` can be used to download multiple files as well: .. code:: python from s3transfer.processpool import ProcessPoolDownloader with ProcessPoolDownloader() as downloader: downloader.download_file('mybucket', 'mykey', 'myfile') downloader.download_file('mybucket', 'myotherkey', 'myotherfile') When running this snippet, the downloading of ``mykey`` and ``myotherkey`` happen in parallel. The first ``download_file`` call does not block the second ``download_file`` call. The snippet blocks when exiting the context manager and blocks until both downloads are complete. Alternatively, the ``ProcessPoolDownloader`` can be instantiated and explicitly be shutdown using :meth:`ProcessPoolDownloader.shutdown`: .. code:: python from s3transfer.processpool import ProcessPoolDownloader downloader = ProcessPoolDownloader() downloader.download_file('mybucket', 'mykey', 'myfile') downloader.download_file('mybucket', 'myotherkey', 'myotherfile') downloader.shutdown() For this code snippet, the call to ``shutdown`` blocks until both downloads are complete. Additional Parameters ===================== Additional parameters can be provided to the ``download_file`` method: * ``extra_args``: A dictionary containing any additional client arguments to include in the `GetObject <https://botocore.amazonaws.com/v1/documentation/api/latest/reference/services/s3.html#S3.Client.get_object>`_ API request. For example: .. code:: python from s3transfer.processpool import ProcessPoolDownloader with ProcessPoolDownloader() as downloader: downloader.download_file( 'mybucket', 'mykey', 'myfile', extra_args={'VersionId': 'myversion'}) * ``expected_size``: By default, the downloader will make a HeadObject call to determine the size of the object. To opt-out of this additional API call, you can provide the size of the object in bytes: .. code:: python from s3transfer.processpool import ProcessPoolDownloader MB = 1024 * 1024 with ProcessPoolDownloader() as downloader: downloader.download_file( 'mybucket', 'mykey', 'myfile', expected_size=2 * MB) Futures ======= When ``download_file`` is called, it immediately returns a :class:`ProcessPoolTransferFuture`. The future can be used to poll the state of a particular transfer. To get the result of the download, call :meth:`ProcessPoolTransferFuture.result`. The method blocks until the transfer completes, whether it succeeds or fails. For example: .. code:: python from s3transfer.processpool import ProcessPoolDownloader with ProcessPoolDownloader() as downloader: future = downloader.download_file('mybucket', 'mykey', 'myfile') print(future.result()) If the download succeeds, the future returns ``None``: .. code:: python None If the download fails, the exception causing the failure is raised. For example, if ``mykey`` did not exist, the following error would be raised .. code:: python botocore.exceptions.ClientError: An error occurred (404) when calling the HeadObject operation: Not Found .. note:: :meth:`ProcessPoolTransferFuture.result` can only be called while the ``ProcessPoolDownloader`` is running (e.g. before calling ``shutdown`` or inside the context manager). Process Pool Configuration ========================== By default, the downloader has the following configuration options: * ``multipart_threshold``: The threshold size for performing ranged downloads in bytes. By default, ranged downloads happen for S3 objects that are greater than or equal to 8 MB in size. * ``multipart_chunksize``: The size of each ranged download in bytes. By default, the size of each ranged download is 8 MB. * ``max_request_processes``: The maximum number of processes used to download S3 objects. By default, the maximum is 10 processes. To change the default configuration, use the :class:`ProcessTransferConfig`: .. code:: python from s3transfer.processpool import ProcessPoolDownloader from s3transfer.processpool import ProcessTransferConfig config = ProcessTransferConfig( multipart_threshold=64 * 1024 * 1024, # 64 MB max_request_processes=50 ) downloader = ProcessPoolDownloader(config=config) Client Configuration ==================== The process pool downloader creates ``botocore`` clients on your behalf. In order to affect how the client is created, pass the keyword arguments that would have been used in the :meth:`botocore.Session.create_client` call: .. code:: python from s3transfer.processpool import ProcessPoolDownloader from s3transfer.processpool import ProcessTransferConfig downloader = ProcessPoolDownloader( client_kwargs={'region_name': 'us-west-2'}) This snippet ensures that all clients created by the ``ProcessPoolDownloader`` are using ``us-west-2`` as their region. � N)�deepcopy)�Config)�MAXINT� BaseManager)�ALLOWED_DOWNLOAD_ARGS�MB�PROCESS_USER_AGENT)�CancelledError�RetriesExceededError)�BaseTransferFuture�BaseTransferMeta)� S3_RETRYABLE_DOWNLOAD_ERRORS�CallArgs�OSUtils�calculate_num_parts�calculate_range_parameter�create_nested_client�SHUTDOWN�DownloadFileRequest�� transfer_id�bucket�key�filename� extra_args� expected_size� GetObjectJob)r r r � temp_filenamer �offsetr c # �r # � [ 5 n S v � [ R " [ R U 5 g 7f�N)�"_add_ignore_handler_for_interrupts�signal�SIGINT)�original_handlers �I/usr/lib/rads/venv/lib/python3.13/site-packages/s3transfer/processpool.py� ignore_ctrl_cr' s$ � � �9�;�� � �M�M�&�-�-�!1�2�s �57c �h � [ R " [ R [ R 5 $ r! )r# r$ �SIG_IGN� � r& r" r" s � � �=�=�� � ���� 7�7r+ c �0 � \ rS rSrS\- S\- S4S jrSrg)�ProcessTransferConfigi � � c �( � Xl X l X0l g)aE Configuration for the ProcessPoolDownloader :param multipart_threshold: The threshold for which ranged downloads occur. :param multipart_chunksize: The chunk size of each ranged download. :param max_request_processes: The maximum number of processes that will be making S3 API transfer-related requests at a time.
