From e9a910b33c7837b4b868e3abda18eb4810df7f02 Mon Sep 17 00:00:00 2001 From: Leah Rowe Date: Sat, 4 Oct 2025 09:14:33 +0100 Subject: config/git: import suckless sbase i currently use the output of sha512sum in several places of xbmk, which is a bit unreliable in case output changes. other cases where i use util outputs in variables are probably reliable, because i'm using mostly posix utilities in those. to mitigate this, i now import suckless sbase, which has a reasonable sha512sum implementation. *every* binary it builds is being placed in build.list, because i'll probably start using more of them. for example, i may start modifying the "date" implementation, adding the GNU-specific options that i need as mentioned on init.sh i'm importing it in util/ because the sha512sum util is needed for verifying project sources, so if sbase itself is a "project source", that means we can into a chicken and egg bootstrapping problem. this is sbase at revision: 055cc1ae1b3a13c3d8f25af0a4a3316590efcd48 Signed-off-by: Leah Rowe --- util/sbase/time.c | 73 +++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 73 insertions(+) create mode 100644 util/sbase/time.c (limited to 'util/sbase/time.c') diff --git a/util/sbase/time.c b/util/sbase/time.c new file mode 100644 index 00000000..60a8c8df --- /dev/null +++ b/util/sbase/time.c @@ -0,0 +1,73 @@ +/* See LICENSE file for copyright and license details. */ +#include +#include + +#include +#include +#include + +#include "util.h" + +static void +usage(void) +{ + eprintf("usage: %s [-p] cmd [arg ...]\n", argv0); +} + +int +main(int argc, char *argv[]) +{ + pid_t pid; + struct tms tms; /* user and sys times */ + clock_t r0, r1; /* real time */ + long ticks; /* per second */ + int status, savederrno, ret = 0; + + ARGBEGIN { + case 'p': + break; + default: + usage(); + } ARGEND + + if (!argc) + usage(); + + if ((ticks = sysconf(_SC_CLK_TCK)) <= 0) + eprintf("sysconf _SC_CLK_TCK:"); + + if ((r0 = times(&tms)) == (clock_t)-1) + eprintf("times:"); + + switch ((pid = fork())) { + case -1: + eprintf("fork:"); + case 0: + execvp(argv[0], argv); + savederrno = errno; + weprintf("execvp %s:", argv[0]); + _exit(126 + (savederrno == ENOENT)); + default: + break; + } + waitpid(pid, &status, 0); + + if ((r1 = times(&tms)) == (clock_t)-1) + eprintf("times:"); + + if (WIFSIGNALED(status)) { + fprintf(stderr, "Command terminated by signal %d\n", + WTERMSIG(status)); + ret = 128 + WTERMSIG(status); + } + + fprintf(stderr, "real %f\nuser %f\nsys %f\n", + (r1 - r0) / (double)ticks, + tms.tms_cutime / (double)ticks, + tms.tms_cstime / (double)ticks); + + if (WIFEXITED(status)) + ret = WEXITSTATUS(status); + + return ret; +} -- cgit v1.2.1
