terminal echo is off after interrupting cvs password entry (:ext, ssh)
situation:
set CVSROOT=:ext:username@servername:/dir
The "ext" is important. You can set up a local cvsroot dir, do a "cvs init" there and then use localhost as server. This bug occured to me on several servers so it is not server dependent.
set CVS_RSH=ssh (should be default anyway)
You will need to run sshd if you use localhost for testing.
Now run "cvs update" somewhere. As long as you have a working CVSROOT somewhere, it is irrelevant if there is a working copy.
When asked for a password, press "STRG+C" to interrupt cvs.
expected result:
cvs gets killed and you are back on your terminal
actual result:
cvs does get killed, but echo is off on your terminal, so you can't see what you type. You have to do "stty echo" or "reset" to see what you are doing again.
Additional info:
I am using cvs 1.11.23, installing 1.12.13 from source with makepkg didn't help.
I am using openssh 5.1p1, using ssh2 didn't help
I am using the kernel 2.6.26.5, standard Arch kernel for i686
I reported it upstream at:
https://savannah.nongnu.org/bugs/?24268
However, I couldn't reproduce it on another system and the cvs-dev couldn't reproduce this either. It is possible, that arch does something different with the signals. Not necessarily wrong, but different. So I put this as "support request" to know what to check in order to get this bug fixed upstream. I don't know much about signals myself.
PS:
Newbie Corner doesn't really fit, but no other forum either. I wanted to report it in the bug tracker, but this might be nonsense, since no arch-dev is needed to fix a problem, only somebody who has a clue what could be wrong and maybe some people reproducing it or telling me, that they cant' reproduce it, even on Arch.

Re: terminal echo is off after interrupting cvs password entry (:ext, ssh)
I would file this on http://bugs.archlinux.org
Might want to post strace of it.

Re: terminal echo is off after interrupting cvs password entry (:ext, ssh)
Hm - didn't want to do that, because this might be Arch related, but it is submitted upstream and probably can't be fixed in arch. Since I have people telling me, that it's okay to do so.. I will do it this evening.
Thank you for the tip with strace, didn't use that one before.
It gives a lot of output before I get the password prompt, but the useful part should be:

Re: terminal echo is off after interrupting cvs password entry (:ext, ssh)
Okay, good news for Arch, bad news for my computer..
I managed to reproduce the bug on an ubuntu machine, but only on high load. So this is not Arch dependent and I won't submit a bug report (until I got new evidence for an arch issue).
I reproduced the bug on my machine withoug high load, but I have a PIII 800 MHz .. might be a time-out issue with not having "enough" cpu power at hand.
For the curious I have the last parts of the strace for
ubunut_idle:
select(6, [5], NULL, NULL, NULL) = 1 (in [5])
--- SIGINT (Interrupt) @ 0 (0) ---
rt_sigprocmask(SIG_SETMASK, ~[RTMIN RT_1], [INT], 8) = 0
write(2, "cvs [update aborted]: received i"..., 48) = 48
close(1) = 0
exit_group(1) = ?and
ubuntu_load:
select(6, [5], NULL, NULL, NULL) = ? ERESTARTNOHAND (To be restarted)
--- SIGINT (Interrupt) @ 0 (0) ---
rt_sigprocmask(SIG_SETMASK, ~[RTMIN RT_1], [INT], 8) = 0
write(2, "cvs [update aborted]: received i"..., 48) = 48
close(1) = 0
exit_group(1) = ?The visible difference in strace is the "ERESTARTNOHAND" in load and "ERESTARTSYS" on my PIII.
(I posted this and more upstream on savannah, of course)
