* NEWS: Mention the bug fix.
* src/shred.c (wipefile): Open the file with O_NONBLOCK.
* tests/shred/fifo.sh: New file.
* tests/local.mk (all_tests): Add the new test.
ls: exclude newline from consideration in line width2026-05-04T22:58:12ZPádraig BradyP@draigBrady.com2026-05-04T14:34:32Zurn:sha1:e63681148123216697701ec9f9750a4ccf0c6671
* src/ls.c (calculate_columns): Treat width as inclusive max.
(print_with_separator): Likewise. Also handle commas explicitly,
since they're not catered for by an implicit newline in the count.
* tests/ls/w-option.sh: Adjust exact-fit column tests.
Note this change also makes the existing `ls -w4 -x -T0 a b` test
behave consistently with other output width limits.
Also add the test case from:
https://github.com/coreutils/coreutils/pull/213
* tests/ls/m-option.sh: Add a test case to ensure appropriate
wrapping when trailing comma at the line limit.
* NEWS: Mention the change in behavior.
unexpand: fix heap overflow2026-04-29T12:16:43ZPádraig BradyP@draigBrady.com2026-04-28T19:33:10Zurn:sha1:b60a159fdc5bfcf9988d3a4cb6f53abe8ad5d35d
* src/unexpand.c (unexpand): Use xinmalloc() to gracefully
handle overflow. Also use the runtime locale specific MB_CUR_MAX
rather than the worst case MB_LEN_MAX.
* tests/unexpand/mb.sh: Add a test case that fails in a default
glibc build with either MB_CUR_MAX or MB_LEN_MAX.
* NEWS: Mention the bug fix.

sort: use more dynamic memory allocation with pipes2026-04-29T12:16:21ZPádraig BradyP@draigBrady.com2026-04-27T14:48:30Zurn:sha1:38cf97c1ff81895ca3c2b20ede817380e7004dcf
The default memory allocation with pipes was too passive/static,
resulting in not allocating enough memory to enable threading.
By dynamically reallocating the buffer when reading from
unknown sized inputs we better use available memory and threads.
$ time seq 10000000 -1 0 | sort-old >/dev/null
real 0m16.523s
user 0m16.900s
sys 0m0.167s
$ time seq 10000000 -1 0 | sort-old -S1G >/dev/null
real 0m12.263s
user 0m29.646s
sys 0m0.527s
$ time seq 10000000 -1 0 | sort-new >/dev/null
real 0m12.994s
user 0m31.266s
sys 0m0.716s
It also avoids the overhead of writing to temp files
for modestly sized inputs. For example the following
input would induce interaction with temp storage:
$ seq 125000 | wc -c
763895
* src/sort.c (sort_buffer_size): Rename to ...
(sort_buffer_policy): ... here, and adjust to set
an initial size and limit, rather than just a size.
(fillbuf): Add a POLICY parameter, and use that
to call maybe_growbuf() as needed.
(maybe_growbuf): Return true if POLICY dictates we
should grow the buffer, and try_growbuf() was
able to reallocate the larger buffer.
* tests/sort/sort-buffer-size.sh: Add a new test.
* tests/local.mk: Reference new test.
* NEWS: Mention the improvement.
