Package: vim
Version: 1:6.3-058+1
Severity: important
When I start vim to edit a file that is already being edited, vim
nicely shows me the "swap file already exists" prompt. If I press any
"normal" (alphanumeric) key here, everything keeps working fine.
However, if I press a cursor key on this screen, vim simple freezes
and refuses to reacted to anything (including ^Z and ^C) except an
external TERM signal.
My cursor keys return the usual \e[A, \e[B, \e[C, \e[D escape
sequences.
The problem seems locale-dependent. if I start vim with
[EMAIL PROTECTED]/tmp> env -i LC_ALL=C vim test
it works fine. If I set LC_ALL to en_US.UTF8 or nl_NL.UTF8 instead of
C, the bug returns. With en_US or en_US.ISO-8859-15, the bug doesn't
occur either. I've tries this using varying terminals (xterm, aterm,
console).
An strace of the frozen process shows
| select(1, [0], NULL, [0], {0, 100000}) = 0 (Timeout)
| ioctl(0, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost -isig -icanon -echo
...}) = 0
| select(1, [0], NULL, [0], {0, 100000}) = 0 (Timeout)
| ioctl(0, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost -isig -icanon -echo
...}) = 0
| select(1, [0], NULL, [0], {0, 100000}) = 0 (Timeout)
| ioctl(0, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost -isig -icanon -echo
...}) = 0
etc. When I press a key, it says:
| select(1, [0], NULL, [0], {0, 100000}) = 0 (Timeout)
| ioctl(0, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost -isig -icanon -echo
...}) = 0
| select(1, [0], NULL, [0], {0, 100000}) = 1 (in [0], left {0, 17000})
| select(1, [0], NULL, [0], NULL) = 1 (in [0])
| read(0, "q", 4096) = 1
| ioctl(0, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost -isig -icanon -echo
...}) = 0
| select(1, [0], NULL, [0], {0, 100000}) = 0 (Timeout)
| ioctl(0, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost -isig -icanon -echo
...}) = 0
(which shows vim does actually receives the key I typed)
after which it returns to the select/ioctl loop.
