Re: [TUHS] SDB debugger

So I definitely remember adb, I liked it for the same reasons that Rob did, it told you the truth. I also remember using a sdb debugger, not sure if it was at Sun or when I was doing a Sys V port. I liked it, it was reasonable. I think dbx ended up becoming the one I used on BSD. Gdb eventually got good enough but I'm with Rob, it was a mess early on. But truth be known, I'm sort of a printf() debugger. The main thing I use gdb for is a stack trace, that's usually enough. The BitKeeper source has this "gem": void gdb_backtrace(void) { FILE *f; char *cmd; unless (getenv("_BK_BACKTRACE")) return; unless ((f = efopen("BK_TTYPRINTF")) || (f = fopen(DEV_TTY, "w"))) { f = stderr; } cmd = aprintf("gdb -batch -ex backtrace '%s/bk' %u 1>&%d 2>&%d", bin, getpid(), fileno(f), fileno(f)); system(cmd); free(cmd); if (f != stderr) fclose(f); } On Fri, May 01, 2020 at 10:52:49PM -0400, Doug McIlroy wrote: -- --- Larry McVoy lm at mcvoy.com http://www.mcvoy.com/lm
