Hi,
Job control still does not work correctly on -CURRENT built on
Aug 11 13:52:57 EST 2002 (~4 hours ago):
$ su
Password:
cinq# suspend
Suspended (signal)
$ fg
su
cinq# suspend
Suspended (signal)
$ fg
su
cinq# Stopped (tty output)
(I get disconnected)
The problems with chpass getting suspended are still there, too.
There also seems to be something wrong with pipes: yes | more will fail
once in a while. 'more' dies like this:
(has just written the first screenful of y's to the screen)
15142 more RET write 78/0x4e
15142 more CALL read(0x4,0xbfbffbe3,0x1)
15142 more RET read -1 errno 5 Input/output error
15142 more CALL write(0x1,0x8061180,0x17)
15142 more GIO fd 1 wrote 23 bytes
"\^[[24;1H\0\0\0\0\^[[K\0\0\^[[?1l\^[>"
15142 more RET write 23/0x17
15142 more CALL fsync(0x2)
15142 more RET fsync 0
15142 more CALL ioctl(0x2,TIOCSETAW,0xbfbffb60)
15142 more RET ioctl -1 errno 5 Input/output error
15142 more CALL exit(0x1)
'yes' dies like this:
(has just written a big block of y's)
14288 yes RET write 16384/0x4000
14288 yes CALL write(0x1,0x804b000,0x4000)
14288 yes RET write -1 errno 32 Broken pipe
14288 yes PSIG SIGPIPE SIG_DFL
more is trying to read a character from the user's tty, but getting EIO
instead.
