Description

Sentry CLOUDSMITH-CLI-2B is an OSError: [Errno 5] Input/output error from cloudsmith push, raised in create_package. That function only writes progress to the terminal and calls the API, and the error has no file name. So the error comes from a write to a terminal that is gone.

When the terminal closes or the SSH session drops while a command runs, the next write to stdout or stderr fails with EIO. The error reaches AliasGroup.main, and the CLI sends it to Sentry as a crash. The CLI cannot fix the terminal, so the report gives us nothing to act on.

This PR makes is_reportable return false for an OSError with errno.EIO. The CLI still shows the error and exits with status 1.

To see the change, run a command with stdout on a pty whose other end is closed:

import os, pty, subprocess
master, slave = pty.openpty()
os.close(master)
subprocess.run(["cloudsmith", "--help"], stdout=slave)

On master, the CLI prints Error: OSError: [Errno 5] Input/output error and sends a report. With this PR, it prints the same line and sends nothing.

Fixes CLOUDSMITH-CLI-2B

Type of Change

• Bug fix
• New feature
• Breaking change
• Documentation update
• Refactoring
• Other (please describe)

Additional Notes

A disk read that fails with EIO is also not reported now. That is a hardware problem, not a CLI bug, and the user still sees the error.

🟡 Changes recommended

The changelog incorrectly guarantees exit status 1 for EIO on a hung-up terminal, while a failed buffered stdout flush during shutdown can still produce status 120.
