Ctrl-C interrupts the whole ssh session while catching by in interactive mode about msys2-runtime

[dscho]

Can you try again after setting MSYS=enable_pcon?

@dscho @jeremyd2019 thanks! I've updated msys and now it works properly even without MSYS=enable_pcon

Observing the same behaviour with ssh.exe shipped with git.. this breaks all workflow for me.

Thanks, it fixes the issue for me!

that restores the correct behaviour, thanks.

Just to clarify, are you talking about running ssh from cmd directly, or running cmd from bash, and then running ssh in that cmd? I tried to reproduce with the former and it didn't seem to reproduce. But there was a commit to upstream cygwin recently that claims to fix a cygwin -> native -> cygwin Ctrl-C issue that seems like it might be related

Update: even from bash -> cmd -> msys2 ssh I still can't dupe it

[jeremyd2019]

I can dupe with Git for Windows but not with "stock" msys2.

[dscho]

@pnuzhdin please test with the artifact from the PR with the proposed fix that is under review.

[dscho]

Well, now you can simply update...

[pnuzhdin]

It seems this issue is reproduced again for:

msys2-launcher 1.5-1
msys2-runtime 3.3.5-1

And having MSYS=enable_pcon doesn't help.

[dscho]

@pnuzhdin any chance that you can bisect through the recent patches to figure out which one re-introduced the regression?

[pnuzhdin]

@dscho I'm unable to do this, sorry

@dscho I'm unable to do this, sorry

No worries, I can't do it either.

On a fresh msys2 install (openssh 8.9p1-3, msys2-runtime 3.3.5-3) this problem shows up when
using a ProxyCommand and the actual proxy command is a plain Windows (non-msys) program. With a direct ssh into the same box CTRL-C works as expected.
