| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | musl libc's mallocng free() may modify errno if kernel does not support MADV_FREE which causes echo to echo with error when it shouldn't. Future versions of POSIX[1] will require that free() leaves errno unmodified but til then, do not rely free() implementation.

* | nproc: port to WIN32 and enable by defaultRon Yorston2021-02-171-0/+30
| | | | | | | | | | | | 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 unconditionalRon Yorston2021-02-122-9/+0
| | | | | | | | | | | | | | 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 sequencesRon Yorston2021-02-031-48/+60
| | | | | | | | | | | | | | | | | | | | | | | | 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.
* | printf: code shrinkRon Yorston2021-01-271-19/+7
| | | | | | | | | | | | | | | | | | | | 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 compilationRon Yorston2021-01-261-5/+4
| | | | | | | | | | | | | | | | | | 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 2Ron Yorston2021-01-253-10/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
