reset: add support for stty and Windows Terminal

2026-05-11T12:54:20+00:00

The 'reset' applet hasn't kept pace with developments elsewhere. We now have support for 'stty sane', so the code in 'reset' which calls that can be enabled. Windows 10 and 11 have updated Terminal and Console programs, with varying features and behaviours. Add ANSI emulation code to handle clearing the scrollback buffer and use ANSI sequences in 'reset' to do that. It was also necessary to retain the explicit call to reset_screen(), or 'reset' didn't work properly in the Terminal I'd installed in Windows 10. Adds 92-128 bytes. (GitHub issue #161)

win32: silence warning in ioctl(2)

2026-05-05T07:10:56+00:00

Silence a compiler warning that 'arg' is an unused variable if neither stty nor ttysize is defined.

win32: add FAST_FUNC annotations

2026-05-04T10:51:00+00:00

I've been far too lax in applying FAST_FUNC annotations. These can make function calls smaller and faster, but only on 32-bit systems and for non-static, non-variadic functions with non-void arguments. Saves 4680 bytes in the 32-bit build; 64-bit builds are unaffected.

Add crond and crontab (#561)

2026-05-03T08:53:07+00:00

* Enable crontab * Enable crond * Allow sendmail to be used in crond This also adds another option to the mingw_popen_fd function to capture stderr as well. And also added the options to support WNOHANG as well as an unused status in mingw_wait3 * Check current uid when running crond * Only show tail for mailto jobs * Use system drive for cron * crond: add missing feature check * crond: use spawn_detach for background operation

win32: disable urandom/zero devices if dd is disabled

2026-04-27T07:40:06+00:00

Support for /dev/urandom and /dev/zero relies on having a working dd. If the dd applet is disabled attempts to access them should fail. Theoretically a third-party dd utility could also work, but let's not encourage that sort of heresy.

win32: improve urandom/zero device handling

2026-04-26T19:49:26+00:00

Rearrange the code to avoid a superfluous process creation. Saves 16 bytes in the 64-bit build, adds 24 in the 32-bit.

win32: expose /dev/urandom and /dev/zero

2026-04-26T09:59:27+00:00

Previously the special devices /dev/urandom and /dev/zero could only be used via the 'dd' applet. They were also used internally by some applets. Expose /dev/urandom and /dev/zero so they can be used as file arguments to applets and a source of redirections in the shell. They're also now visible to 'stat' and 'ls', but only if given as an explicit argument. Adds 122-144 bytes. (GitHub issues #98, #282)

Win32: trivial refinements (#577)

2026-04-18T09:27:47+00:00

* win32: fnmatch2 minor refinements (no-op) With beacket, add '\' to the switch/case, and at fnmatch, pre-calc the two most used flags (CASEFOLD and PATHNAME) once on init. Negligible perf impact, and happens to save few bytes in x64. * win32: actype: trivial refinments (no-op) NULL was used in actype.h but requires stddef.h - which we don't include, so use (int*)0 which also expresses it more clearly. Remove "#include " at actype.c, which we don't need anymore. * scripts/patbench.sh: make executable (chmod +x)

win32: fnmatch2: replace if-else-... with switch/case

2026-04-16T09:42:13+00:00

This was done to be more concise, but it also happens to speed up the two slowest test patterns by about ~ 30%, and without measurable impact on any of the other test patterns (nor the correctness). Maybe the stars aligned for compiler optimizations. We'll take it. Here are results of scripts/patbench.sh with recent iterations of fnmatch, from most recent to the original old fnmatch: CURRENT results: [ 1] 107 ms OK (M:-----) '' [ 2] 105 ms OK (M:12345) '*' [ 3]
