Fixes ipython#12264 Add system_raise_on_error configuration option that raises CalledProcessError when shell commands executed via the ! operator return non-zero exit status. This brings similar error-handling behavior to the ! operator as was added to %%bash magic in PR ipython#11287. Changes: - Add system_raise_on_error Bool traitlet config (default: False) - Import CalledProcessError from subprocess - Modify system_piped() to raise on non-zero exit when enabled - Modify system_raw() to raise on non-zero exit when enabled - Modify getoutput() to raise on non-zero exit when enabled (uses get_output_error_code to capture exit status) When enabled, users can halt notebook execution on command failures: get_ipython().system_raise_on_error = True !false # Now raises CalledProcessError Note: A follow-up PR to ipykernel will be needed to support this in Jupyter notebooks, as ZMQInteractiveShell overrides system_piped().

Bumping this. @Carreau would you be able to review it if you have a few minutes to spare? Many thanks! |

Pinging this, is there any interest in this PR? Would be nice to at least get some feedback on why this didn't make the cut |

configuration option in ZMQInteractiveShell.system_piped() override. This complements IPython PR #15073 (ipython/ipython#15073) that adds the system_raise_on_error config option. Since ZMQInteractiveShell overrides system_piped() for Windows UNC path handling, it needs to also check the system_raise_on_error config and raise CalledProcessError on non-zero exit status.

Fixes #12264
Add system_raise_on_error configuration option that raises CalledProcessError when shell commands executed via the ! operator return non-zero exit status. This brings similar error-handling behavior to the ! operator as was added to %%bash magic in PR #11287.
Changes:
When enabled, users can halt notebook execution on command failures:
get_ipython().system_raise_on_error = True
!false # Now raises CalledProcessError
Note: A follow-up PR to ipykernel will be needed to support this in Jupyter notebooks, as ZMQInteractiveShell overrides system_piped().
