2013-03-19rc: avoid undefined CXi Wang1-4/+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
2013-03-19libsec: avoid undefined CXi Wang1-2/+1
gcc compiles `p + length < p' into 'length < 0' since pointer overflow is undefined behavior in C. This breaks the check against a large `length'. Use `length > pend - p' instead. There's no need to check `length < 0' since `length' is from length_decode() and should be non-negative. === Try the simplified code. void bar(void); void foo(unsigned char *p, int length) { if (p + length < p) bar(); } $ gcc -S -o - t.c -O2 ... foo: .LFB0: .cfi_startproc testl %esi, %esi js .L4 rep ret .L4: jmp bar .cfi_endproc Clearly `p' is not used at all.

Ubuntu Precise seems to have a buggy X server that sometimes fails at XCopyArea. Let devdraw do it itself. This will slow down remote X a little bit, but slow and correct is better than fast and broken. R=rsc https://codereview.appspot.com/7310069

2012-09-23acme: mouse movement for DelRuss Cox5-8/+62
If the mouse was in the tag of the old window, it was most likely pointing at Del. If bringing up a new window from below and not moving the mouse somewhere else, adjust it so that it ends up pointing at Del in the replacement window's tag too. This makes it easy to Del a sequence of windows in a column, from top to bottom. http://www.youtube.com/watch?v=ET8w6RT6u5M R=r http://codereview.appspot.com/6558047
