Re: [TUHS] v7 source code for sh

Rob Pike: I did the same to adb, which turned out to have a really good debugger hidden under a few serious bugs of its own, which I fixed. ===== Memories. Was it you who replaced ptrace with /proc in adb, or did I do that? I do remember I was the one who took ptrace out of sdb (which a few 1127-ers, or perhaps 112-ers on alice and rabbit still used). After which I removed ptrace from the kernel, and from the copy of the V8 manual in the UNIX room. Conveniently ptrace occupied two facing pages; I glued them together. I also later did some work to try to isolate the target-dependent parts of adb and to make them work in host-independent ways--e.g. assembling ints byte-by-byte rather than assuming byte order--to make it easier to make a cross adb, e.g. to examine PDP-11 or 68K core dumps on a VAX. I miss adb; maybe it's time to revive it, though these days I'd be tempted to rewrite it in Python so I could just load the right module at runtime to pick the desired target. Norman Wilson Toronto ON
