2013-08-069term: set TERM=dumb instead of TERM=9termRuss Cox4-1/+13
Everyone seems to assume that TERM != dumb implies ANSI escape codes are okay. In fact, many people assume that unconditionally, but it is easier to argue back about TERM=dumb than TERM=9term. This applies to acme win too, because they share the code. Set termprog=9term or termprog=win for clients who need to know. R=rsc CC=r https://codereview.appspot.com/12532043

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
