Summary0005740: Suspend/resume of "sudo vi" broken in sudo-1.7.4p5-9
DescriptionAfter updating to sudo-1.7.4p5-9, suspend/resume doesn't work. Reverting to sudo-1.7.4p5-7 corrects the issue.
Steps To Reproduce1) type sudo vi
2) type password (if required)
3) hit control-Z
4) type fg - note that screen fails to redraw)
5) hit Enter twice - note that vi is not responding properly
6) hit control-Z - terminal seems stuck; must disconnect from terminal session to recover
(Steps 5 & 6 aren't critical - I've tried doing other things here but no success.)

Additional InformationThis issue is seen with upstream OS as well -- sudo-1.7.4p5-7.el6.x86_64 is OK but sudo-1.7.4p5-9.el6_2.x86_64 is broken.
TagsNo tags attached.

sudo release notes suggest a fix went into 1.8.1.

"The fix for resuming a suspended shell in 1.7.5 caused problems with resuming non-shells on Linux. Sudo will now save the process group ID of the program it is running on suspend and restore it when resuming, which fixes both problems."

this is now filed as an upstream bug:

Although I can't read the upstream bug report, it's possible to install the latest Sudo RPM from www.sudo.ws, e.g. sudo-1.7.10-8.el6.i386.rpm from http://www.sudo.ws/sudo/download.html#binary, and that fixed the problem for me.

I'd like to give this a higher priority, as vim is a common and much-used config file editor, sudo is a common and much-used way to give it root access, and suspending vim is a common and much-used action. I usually get bitten by this about once a week, whenever I'm on a centos box instead of Debian/Ubuntu, which doesn't seem to have the problem.

I can confirm the upstream fix has propagated to CentOS (happened quite a while ago). This bug can be closed.
