However, request metadata may be the right\n+ choice in certain scenarios, such as to maintain some debugging data\n+ across all follow-up requests (e.g. the source URL).\n+\n+ A common use of request metadata is to define request-specific\n+ parameters for Scrapy components (extensions, middlewares, etc.). For\n+ example, if you set ``dont_retry`` to ``True``,\n+ :class:`~scrapy.downloadermiddlewares.retry.RetryMiddleware` will never\n+ retry that request, even if it fails. See :ref:`topics-request-meta`.\n+\n+ You may also use request metadata in your custom Scrapy components, for\n+ example, to keep request state information relevant to your component.\n+ For example,\n+ :class:`~scrapy.downloadermiddlewares.retry.RetryMiddleware` uses the\n+ ``retry_times`` metadata key to keep track of how many times a request\n+ has been retried so far.\n+\n+ Copying all the metadata of a previous request into a new, follow-up\n+ request in a spider callback is a bad practice, because request\n+ metadata may include metadata set by Scrapy components that is not\n+ meant to be copied into other requests. For example, copying the\n+ ``retry_times`` metadata key into follow-up requests can lower the\n+ amount of retries allowed for those follow-up requests.\n+\n+ You should only copy all request metadata from one request to another\n+ if the new request is meant to replace the old request, as is often the\n+ case when returning a request from a :ref:`downloader middleware\n+ <topics-downloader-middleware>` method.\n+\n+ Also mind that the :meth:`copy` and :meth:`replace` request methods\n+ :doc:`shallow-copy <library/copy>` request metadata.\n \n .. attribute:: Request.cb_kwargs\n \ndiff --git a/scrapy/cmdline.py b/scrapy/cmdline.py\nindex 761f9df83..6580ba9ce 100644\n--- a/scrapy/cmdline.py\n+++ b/scrapy/cmdline.py\n@@ -71,10 +71,12 @@ def _get_commands_dict(settings, inproject):\n \n \n def _pop_command_name(argv):\n- for i, v in enumerate(argv):\n- if v.startswith('-'):\n- continue\n- return argv.pop(i)\n+ i = 0\n+ for arg in argv[1:]:\n+ if not arg.startswith(\"-\"):\n+ del argv[i]\n+ return arg\n+ i += 1\n \n \n def _print_header(settings, inproject):\n@@ -86,11 +88,12 @@ def _print_header(settings, inproject):\n print(f\"Scrapy {version} - no active project\\n\")\n \n \n-def _print_commands(settings, inproject, cmds):\n+def _print_commands(settings, inproject):\n _print_header(settings, inproject)\n print(\"Usage:\")\n print(\" scrapy <command> [options] [args]\\n\")\n print(\"Available commands:\")\n+ cmds = _get_commands_dict(settings, inproject)\n for cmdname, cmdclass in sorted(cmds.items()):\n print(f\" {cmdname:<13} {cmdclass.short_desc()}\")\n if not inproject:\n@@ -106,7 +109,6 @@ def _print_unknown_command(settings, cmdname, inproject):\n print('Use \"scrapy\" to see available commands')\n \n \n-# TODO: Confusion, can be improved.\n def _run_print_help(parser, func, *a, **kw):\n try:\n func(*a, **kw)\n@@ -134,9 +136,9 @@ def execute(argv=None, settings=None):\n \n inproject = inside_project()\n cmds = _get_commands_dict(settings, inproject)\n- cmdname = _pop_command_name(argv[1:])\n+ cmdname = _pop_command_name(argv)\n if not cmdname:\n- _print_commands(settings, inproject, cmds)\n+ _print_commands(settings, inproject)\n sys.exit(0)\n elif cmdname not in cmds:\n _print_unknown_command(settings, cmdname, inproject)\n@@ -152,7 +154,7 @@ def execute(argv=None, settings=None):\n settings.setdict(cmd.default_settings, priority=\"command\")\n cmd.settings = settings\n cmd.add_options(parser)\n- opts, args = parser.parse_known_args(argv[1:])\n+ opts, args = parser.parse_known_args(args=argv[1:])\n _run_print_help(parser, cmd.process_options, args, opts)\n \n cmd.crawler_process = CrawlerProcess(settings)\n", "difficulty": "1"} |
