-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hello Coreutils maintainers,
I believe I've found a bug in the coreutils' ls command.
I was watching a file with watch and ls -l while it was being updated, but
sometimes I saw that the time would display a year instead of an hour and
minute.
Later I reproduced this issue by doing the following:
- open a terminal emulator
- create two tabs
- run `touch test`
- in tab 1, run
either
while (true); do { ls -l test; }; done;
or
while (true); do { ls -l test | grep -F 2025; }; done;
- in tab 2, run
while (true); do {
head -c 1 </dev/urandom | grep '[0-9]' | xargs -r -I LENGTH truncate -cs
LENGTH test;
}; done;
One tab randomly changes the length of file, while the other shows ls -l of the
tile.
In tab 1 I see this:
-rw-r--r-- 1 katarzyna katarzyna 9 Jan 20 00:57 test
-rw-r--r-- 1 katarzyna katarzyna 9 Jan 20 00:57 test
-rw-r--r-- 1 katarzyna katarzyna 9 Jan 20 00:57 test
-rw-r--r-- 1 katarzyna katarzyna 9 Jan 20 00:57 test
-rw-r--r-- 1 katarzyna katarzyna 2 Jan 20 2025 test
-rw-r--r-- 1 katarzyna katarzyna 2 Jan 20 00:57 test
-rw-r--r-- 1 katarzyna katarzyna 2 Jan 20 00:57 test
-rw-r--r-- 1 katarzyna katarzyna 2 Jan 20 00:57 test
-rw-r--r-- 1 katarzyna katarzyna 2 Jan 20 00:57 test
Do you know what might be causing this if it's my system instead of coreutils'
ls?
