[DragonFlyBSD - Bug #2274] C12 problem on leaf.dragonflybsd.org

[Alex Hornung via Redmine]

Issue #2274 has been updated by Alex Hornung.

Priority changed from Normal to Low

I've added some very simple "instrumentation", printing a dot "." when it calls tcsetattr to disable local echo, and a dash "-" when it restores the local echo. The outcome is:

Encrypt public-key (y/n) ? .-.-.-.-.-y.-
Choose password: /root/caesarion/public-key: .-.-y.-.-.-y.-.-y.-.-y.-.-y.-.-y.-.-y.-.-y.-.-y.-.-y.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-n.-.-.-m.-.-o.-.-o.-.-.-o.-.-o.-.-o.-.-.-.-.-.-.-.-.-.-.-.

As you can see, this looks more like a problem with the code. It keeps toggling between one and the other, and every time you press a button, it restores the old settings first, before taking the input, it seems.

Disabling local echo itself definitely works just fine, because it's used in e.g. tcplay.

In any case I'll look a bit further into this.

Cheers,
Alex

Dear DragonFlyBSD bugs,

I reported this problem just recently, and then mistakenly believed an O/S
upgrade on
leaf.dragonflybsd.org had solved the problem. Unfortunately, that was not
the case (I
had changed the code during testing/debugging and had forgot that I had
changed
the code, which led to me believing the problem had been solved).

The problem is with C12 (C12G22r2) operation on leaf.dragonflybsd.org; the
source
code can be downloaded from:

http://www.leopard.uk.com/C12

The problem manifests as a termios(4)/Terminal problem, e.g.

Local echo is not switched off (there are probably other problems
aswell).


Since C12G22r2 works fine on OpenBSD-4.7/i386 and
FreeBSD-9.0/i386, I conclude the problem is with
DragonFlyBSD.
