Incorrectly handles SIGINT

[AMDmi3]

So I run pkg upgrade (pkg 1.16.3), it shows what's it going to do and asks Proceed with this action? [Y/n]:
I hit ^C to interrupt it, but instead it proceeds:

...
Number of packages to be upgraded: 10
Number of packages to be reinstalled: 5

The operation will free 8 MiB.

Proceed with this action? [Y/n]: ^C

By /tmp after the prompt I suspect that multiple processes are involved here, one of which is terminated, but another erroneously continues.

I'm seeing the same issue here, being able to use CTRL-C to actually stop pkg would be good.

Packaged ports from latest, following a major upgrade of base (without pkgbase) from 13.2-RELEASE-p7 to 14.0-RELEASE-p2.

In this case, I keyed Control-C (00:01:32 on the timeline of a screen recording) after it became clear that n would not have the required effect:

00:37:18 on the timeline, with an assumption that things would be endless following the attempted cancellation, I restarted the OS:

Please note, I don't need help with this particular package upgrade scenario; it was a test. No frustration for me.

The three frames from the recording are, partly, to demonstrate the potential for a user to be frustrated in an OS upgrade situation.

Fixed?

From ports-mgmt/pkg: update to 1.21.0 · freebsd/freebsd-ports@c923e0d (2024-04-02):

• support job cancellation (packagekit support)

[leahneukirchen]

I just reported this as https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=280092

It's still an issue in 1.21.3.

(Note that a similar behavior happens on EOF = ^D, for different internal reasons maybe.)
