sh: Increase default history size to POSIX mandated minimum of 128

2026-04-13T23:06:41+00:00

The default history size in bin/sh is currently 100 however POSIX.1-2024
mandates that a default greater than or equal to 128 shall be used,
therefore this increases the default history size in /bin/sh to 128.

uuidgen: generate UUIDs in bounded batches to respect kernel limit

2026-03-07T07:51:16+00:00

The uuidgen(2) system call enforces a hard upper limit of 2048 UUIDs per
invocation. uuidgen(1) previously attempted to generate arbitrary counts
in a single call and allocated memory accordingly, leading to EINVAL
errors, unnecessary memory usage, and potential overflow risks.

Generate UUIDs in fixed-size batches, streaming output incrementally
while preserving existing semantics. Mirror the kernel limit explicitly
since it is not exposed via a public interface.

/bin/ps: Fix display of negative nice values on ARMv7/aarch64

2026-03-07T07:51:14+00:00

On Arm-based systems (and maybe others), 'char' defaults to unsigned,
causing negative nice values to be displayed incorrectly (e.g., 246
instead of -10). Explicitly using 'signed char' ensures consistent
behaviour across architectures.

[ tested on RPI2 and generic aarch64 qemu install ]

Before:
  # /usr/bin/nice --10 ps -l | awk '(NR == 1 || $(NF-1) == "ps")'
  UID   PID  PPID C PRI  NI  VSZ  RSS MWCHAN  STAT TT     TIME COMMAND
    0 23606 22800 2 -32 246 5400 2544 -       R<+   0  0:00.06 ps -l

After:
  # /usr/bin/nice --10 ps -l | awk '(NR == 1 || $(NF-1) == "ps")'
  UID   PID  PPID C PRI  NI  VSZ  RSS MWCHAN  STAT TT     TIME COMMAND
    0 23614 22800 3 -32 -10 5400 2544 -       R<+   0  0:00.05 ps -l

ed: add unicode support for the l (list) command

2026-03-01T11:28:29+00:00

Use mbrtowc()/iswprint()/wcwidth() in put_tty_line() so that
the l command displays valid multibyte characters as-is instead
of escaping each byte as octal.

Column wrapping now correctly accounts for character display
width (including double-width CJK characters).

Invalid or incomplete UTF-8 sequences and non-printable
characters are still escaped as octal.
