nproc: port to WIN32 and enable by default

2021-02-17T13:55:12+00:00

Use the WIN32 API GetProcessAffinityMask() to obtain the number of processors configured and the number available to the current process. This only works for up to 64 processors.

win32: make readlink(2) implementation unconditional

2021-02-12T14:02:28+00:00

There doesn't seem to be much advantage in having readlink(2) as a configuration option. Making it unconditional reduces divergence from upstream and allows the removal of a check for ENOSYS that's been in busybox-w32 since the start.

printf: better support for escape sequences

2021-02-03T14:14:37+00:00

Upstream printf outputs one character at a time which doesn't play well with emulation of ANSI escape sequences. Previous workarounds for this only applied in limited circumstances. Try a different approach: replace putchar() and printf() calls in the printf applet with custom routines which store the output in memory. It's only really output at the end of the program or when a newline is detected and a non-trivial amount has been collected.

nl: ensure '-b n' option displays file content

2021-02-02T16:37:41+00:00

The command 'nl -b n' should output no line numbers, just some spaces as a placeholder followed by the actual file content. Add tests for line numbering by cat and nl. The correct results were obtained from coreutils. function old new delta print_numbered_lines 152 157 +5 .rodata 182456 182453 -3 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/1 up/down: 5/-3) Total: 2 bytes Signed-off-by: Ron Yorston Signed-off-by: Denys Vlasenko

printf: code shrink

2021-01-27T12:46:44+00:00

Instead of constructing null-terminated strings to print, output the characters between the 's' and 't' pointers using fwrite(). This avoids having to output two separate strings when an escaped literal NUL character is encountered in the format string. Saves 32 bytes.

stat: improve conditional compilation

2021-01-26T14:50:34+00:00

If FEATURE_READLINK2 isn't enabled: - in print_stat() combine the code for 'n' and 'N' format; - in do_stat() let the compiler figure out that it doesn't need to emit code to print the symbolic link.

tls: avoid unnecessary changes to POSIX build, part 2

2021-01-25T14:15:02+00:00

On reflection, the previous commit may have been ill-advised. There are many calls to open_read_close() and most shouldn't be able to access special devices. (Though in practice only a few are enabled in busybox-w32.) Nonetheless, I've implemented a new mechanism which uses the macro MINGW_SPECIAL() to mark calls to functions that are allowed to access special devices. An unrelated change is to avoid compiling fputs_stdout() in coreutils/printf.c for the POSIX build.
