* Trivial changes: whitespace and modes.Dan Cross2020-01-105-10/+10
| | | | | | | | | Remote whitespace at the ends of lines. Remove blank lines from the ends of files. Change modes on source files so that they are not executable. Signed-off-by: Dan Cross <cross@gajendra.net>

* rc: use proper type for storing ulimit valuesRay Lai2018-01-171-6/+7
| | | | | | | rc on amd64 stores ulimit values as 32-bit int, but the limits on OpenBSD amd64 can exceed 2^31, so "ulimit -a" shows some values as negative. This is a problem when I want to increase my ulimit but the hard ulimit values are printed as negative.
* all: remove .cvsignore filesKare Nuorteva2017-09-141-3/+0
| | | | | | | | | | Rename following .cvsignore files to .gitkeep since they are required by the build (directories must exist before build): - bin/fossil/.gitkeep - bin/fs/.gitkeep - bin/venti/.gitkeep Change-Id: I9c2865058480cffb3a4613f25e2eca1f7e5578c0
* rc: avoid undefined CXi Wang2013-03-191-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two bugs in pdec() on INT_MIN: * wrong output. `n = 1-n' should be `n = -1-n' when n is INT_MIN. * infinite loop. gcc optimizes `if(n>=0)' into `if(true)' because `-INT_MIN' (signed integer overflow) is undefined behavior in C, and gcc assumes the negation of a negative number must be positive. The resulting binary keeps printing '-' forever given INT_MIN. Try the simplified pdec.c below. $ gcc pdec.c $ ./a.out -2147483648 --214748364* $ gcc pdec.c -O2 $ ./a.out -2147483648 <infinite loop> $ gcc pdec.c -O2 -D__PATCH__ $ ./a.out -2147483648 -2147483648 === pdec.c === #include <stdio.h> #include <stdlib.h> #include <limits.h> #define io void void pchr(io *f, int c) { putchar(c); } void pdec(io *f, int n) { if(n<0){ #ifndef __PATCH__ n=-n; if(n>=0){ pchr(f, '-'); pdec(f, n); return; } /* n is two's complement minimum integer */ n = 1-n; #else if(n!=INT_MIN){ pchr(f, '-'); pdec(f, -n); return; } /* n is two's complement minimum integer */ n = -(INT_MIN+1); #endif pchr(f, '-'); pdec(f, n/10); pchr(f, n%10+'1'); return; } if(n>9) pdec(f, n/10); pchr(f, n%10+'0'); } int main(int argc, char **argv) { int n = atoi(argv[1]); pdec(NULL, n); putchar('\n'); } R=rsc CC=plan9port.codebot https://codereview.appspot.com/7241055

| | | | | | | | | | | | Save the value of `runq' at the start of the function, so that the `pc' update at the end does work on that original value, and not on a probably modified value of `runq'. fixes #14 http://code.swtch.com/plan9port/issue/14/ http://codereview.appspot.com/104066
