| * ls: don't output any colors with TERM=dumbSören Tempel2021-06-041-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The TERM variable is usually set to "dumb" to indicate that the terminal does not support any ANSI escape sequences. Presently, ls does not honor this variable and outputs colors anyhow which results in unreadable output, unless the user explicitly disables colors using `ls --color=never`. The rational behind this change is that ls should "just work" by default, even on dumb terminals. For this reason, this patch adds a check which additionally consults the TERM variable before printing any colors. This is analogous to the existing check for ensuring that standard output is a tty. As such, colors can still be forced with `--color=force`, even if TERM is set to dumb. function old new delta is_TERM_dumb - 40 +40 ls_main 579 598 +19 .rodata 103246 103251 +5 ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 2/0 up/down: 64/0) Total: 64 bytes Signed-off-by: Sören Tempel <soeren+git@soeren-tempel.net> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the functions used to update timestamps in touch. Before, utimes() and lutimes() were used, which had certain disadvantages. They are unable to handle nanosecond timestamps, and implementations of certain features like -a and -m require running stat() in a loop. Almost all implementations of utimes() and lutimes() are wrappers for utimensat(), this is the case for glibc, ulibc and musl libc. function old new delta __futimens_time64 - 24 +24 __lutimes_time64 80 - -80 touch_main 539 456 -83 ------------------------------------------------------------------------------ (add/remove: 2/2 grow/shrink: 0/1 up/down: 24/-163) Total: -139 bytes Signed-off-by: urmum-69 <urmum69@snopyta.org> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* | 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.
