Thanks for bpython, I love it's versatility and ability to make sensible suggestions and show documentation on-the-fly.\r\n\r\nOne of my use-cases is using it alternatingly with the shell (e.g. bash), and switching with Ctrl-Z (SIGSTOP) and fg (shell-builtin to foreground bpython again).\r\n\r\nThis use-case became broken at some point.\r\n\r\nSteps to reproduce:\r\n- Open a Terminal, e.g. xfce4-terminal 0.8.10 (shouldn't matter though), with some shell, e.g. bash 5.1.12(1)-release (shouldn't matter though)\r\n- Start bpython (I'm using 0.22.1 with Python 3.9.9, according to bpython)\r\n- Press Ctrl-Z (for some reason, SIGSTOP works as intended, and does not cause a crash.)\r\n\r\nExpected behavior:\r\n\r\n```console\r\nbash$ bpython\r\nbpython Version 0.22.1 mit Python 3.9.9 /usr/bin/python3\r\n\u003e\u003e\u003e \r\n[2]+  Angehalten              bpython\r\n[$? = 147]\r\n\r\nbash$ jobs\r\n[1]+  Angehalten              bpython\r\n\r\nbash$\r\n```\r\n\r\nActual behavior:\r\n\r\n```console\r\nbash$ bpython\r\nbpython Version 0.22.1 mit Python 3.9.9 /usr/bin/python3\r\n\u003e\u003e\u003e ^Z\r\nTraceback (most recent call last):\r\n  File \"/usr/bin/bpython\", line 33, in \u003cmodule\u003e\r\n    sys.exit(load_entry_point('bpython==0.22.1', 'console_scripts', 'bpython')())\r\n  File \"/usr/lib/python3/dist-packages/bpython/curtsies.py\", line 248, in main\r\n    repl.mainloop(True, paste)\r\n  File \"/usr/lib/python3/dist-packages/bpython/curtsies.py\", line 180, in mainloop\r\n    for e in inputs:\r\n  File \"/usr/lib/python3/dist-packages/bpython/curtsies.py\", line 261, in _combined_events\r\n    e = event_provider.send(timeout)\r\n  File \"/usr/lib/python3/dist-packages/curtsies/input.py\", line 212, in send\r\n    return self._send(timeout)\r\n  File \"/usr/lib/python3/dist-packages/curtsies/input.py\", line 264, in _send\r\n    stdin_ready_for_read, event = self._wait_for_read_ready_or_timeout(\r\n  File \"/usr/lib/python3/dist-packages/curtsies/input.py\", line 170, in _wait_for_read_ready_or_timeout\r\n    (rs, _, _) = select.select(\r\n  File \"/usr/lib/python3/dist-packages/bpython/curtsiesfrontend/repl.py\", line 613, in sigtstp_handler\r\n    self.__exit__()\r\nTypeError: __exit__() missing 3 required positional arguments: 'exc_type', 'exc_val', and 'exc_tb'\r\n[$? = 1]\r\n\r\nbash$ jobs\r\n\r\nbash$\r\n```\r\n\r\n(\"Angehalten\" is German for \"Stopped\".)","author":{"url":"https://github.com/BenWiederhake","@type":"Person","name":"BenWiederhake"},"datePublished":"2022-01-08T11:52:59.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/948/bpython/issues/948"}
