Hi,
s-nail 14.8.16-1 on Arch Linux. I was writing an email and pasted text
from the web browser into the terminal. It contained tabs. The pasted
text had "[ERR_TOO_LONG]" added throughout.
What's written to the terminal, captured by script(1), has lots of
Ctrl-Hs to backspace over what's already written. Here's an example.
I've folded the single line.
Date & Time ^H^H^H^H^H^H^H^H^H^H^H^H ^H^H^H^H^H^H^H^H
^H^H^H^HDate & Time [ERR_TOO_LONG]Location ^H^H^H^H^H^H^H^H^H^H^
H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H
^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H
^H^H^H^H^H^H^H^H^H^H^H^H^HDate & Time [ERR_TOO_LONG]Location [ER
R_TOO_LONG]Description^M
The system calls captured by strace starting with the end of "Time "
above.
read(0, "m", 1) = 1
write(1, "m", 1) = 1
read(0, "e", 1) = 1
write(1, "e", 1) = 1
read(0, " ", 1) = 1
write(1, " ", 1) = 1
read(0, "\t", 1) = 1
rt_sigprocmask(SIG_BLOCK, ~[ILL ABRT BUS FPE KILL SEGV CHLD STOP RTMIN
RT_1], [], 8) = 0
stat("*", 0x7ffcba68b710) = -1 ENOENT (No such file or
directory)
stat("*.gz", 0x7ffcba68b710) = -1 ENOENT (No such file or
directory)
stat("*.xz", 0x7ffcba68b710) = -1 ENOENT (No such file or
directory)
stat("*.bz2", 0x7ffcba68b710) = -1 ENOENT (No such file or
directory)
Why stat globs? And if * is ENOENT then the others aren't going to fare
better.
rt_sigprocmask(SIG_BLOCK, [CHLD], NULL, 8) = 0
open(".", O_RDONLY|O_NONBLOCK|O_DIRECTORY|O_CLOEXEC) = 4
fstat(4, {st_mode=S_IFDIR|0750, st_size=12288, ...}) = 0
getdents(4, /* 276 entries */, 32768) = 9000
getdents(4, /* 0 entries */, 32768) = 0
close(4) = 0
rt_sigprocmask(SIG_UNBLOCK, [CHLD], NULL, 8) = 0
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
write(1, "\10\10\10\10\10\10\10\10\10\10\10\10
\10\10\10\10\10\10\10\10"..., 62) = 62
That will be the "[ERR_TOO_LONG]" making its first appearance.
read(0, "L", 1) = 1
write(1, "L", 1) = 1
read(0, "o", 1) = 1
write(1, "o", 1) = 1
read(0, "c", 1) = 1
write(1, "c", 1) = 1
So it seems there's tab completion of filenames in the midst of writing
an email. That seems of rare use, but a source of frequent annoyance.
How is it disabled?
Cheers, Ralph.
