Re: [TUHS] getting nroff to underline in v6,v5

by Doug McIlroy

> It seems that nroff had the ability to show underlined text very early Pre-Unix roff had the .ul request. Thus I expect (but haven't checked) that it was in Unix roff. It would be very surprising if nroff, which was intended to be more capable that roff, didn't have some underlining facility right from the start. Doug

Re {TUHS} Synchronous vs Asynchronous IO in Unix

by Doug McIlroy

Unix was what the authors wanted for a productive computing environment, not a bag of everything they thought somebody somewhere might want. One objective, perhaps subliminal originally, was to make program behavior easy to reason about. Thus pipes were accepted into research Unix, but more general (and unruly) IPC mechanisms such as messages and events never were. The infrastructure had to be asynchronous. The whole point was to surmount that difficult model and keep everyday programming simple. User visibility of asynchrony was held to a minimum: fork(), signal(), wait(). Signal() was there first and foremost to support SIGKILL; it did not purport to provide a sound basis for asynchronous IPC. The complexity of sigaction() is evidence that asynchrony remains untamed 40 years on. Doug

Re: [TUHS] Questions regarding early Unix contributors

by Doug McIlroy

I can assure you that Lorinda Cherry wrote most of the important code in WWB, including style and diction. The idea for them came from Bill Vesterman at Rutgers. Lorinda already had parts, a real tour de force, which assigned parts of speech to words in a text. Style was the killer app for parts and was running within days of his approach to the labs wondering whether such a thing could be built. Lorinda also wrote deroff, which these tools of course needed. WWB per se was packaged by USDL; I am sorry I can't remember the name of the guiding spirit. So Lorinda's code detoured through there on its way into research Unix. Chris van Wyk was cvw. He was at Bell Labs, not BSD. Chuck Haley is indeed Charles B. Haley. Andy Koenig was ark.

Questions regarding early Unix contributors

by Norman Wilson

A few scattered answers, some redundant with those of others: -- Lorinda Cherry (llc) worked at Bell Labs. She wrote diction (and the rest of the Writer's Workbench tools) there, in the early 1980s; if some people saw it first in BSD releases that is just an accident of timing (too late for V7) and exposure (I'm pretty sure it was available in the USG systems, which weren't generally accessible until a year or two later). Lorinda is one of the less-known members of the original Computer Science Research Center who nevertheless wrote or co-wrote a lot of things we now take for granted, like dc and bc and eqn and libplot. Checking some of this on the web, I came across an interesting tidbit apparently derived from an interview with Lorinda: http://www.princeton.edu/~hos/frs122/precis/cherry2.htm I wholly endorse what she says about UNIX and the group it came from. One fumble in the text: `Bob Ross' who liked to break programs is surely really Bob Morris. -- So far as I know, Tom Duff (td) was never at Berkeley. He's originally from Toronto; attended U of T; was at Lucasfilm for a while (he has a particular interest in graphics, though he is a very sharp and subtle programmer in general); started at Bell Labs in 1984, not long before I did. He left sometime in the 1990s, lives in Berkeley CA, but works neither at UCB nor at Google but at Pixar. -- T. J. Kowalski (frodo) was at Bell Labs; when I was there he worked in the research group down the hall (Acoustics, I think), with whom Computer Science shared a lot of UNIX-releasted stuff. Ted is well-known for his work on fsck, but did a lot of other stuff, including being the first to get Research UNIX to work on the MicroVAX II. He also had a high-quality mustache. -- Andrew Koenig (ark) was part of the Computer Science group when I was there in the latter 1980s. He was a early adopter of C++. asd, the automatic-software distributor we used to keep the software in sync on the 20-or-so systems that ran Research UNIX, was his work. -- Mike Tilson was, I think, one of the founders of HCR (Human Computing Resources), a UNIX-oriented software company based in Toronto in the early 1980s. The company was later acquired by SCO, in the days when SCO was still a technical company rather than a den of lawyers. -- Peter Honeyman (honey) was never, I think, at Berkeley, though he is certainly of the right character. In the 1980s he was variously (sometimes concurrently?) working for some part of AT&T and at Princeton. For many years now he has been in Ann Arbor MI at the University of Michigan, where his still-crusty manner appears not to interfere with his being a respected researcher and much-liked teacher.

I found out that the book "Life with Unix" by Don Libes and Sandy Ressler has a seven page listing of Unix notables, and I'm using that to fill gaps in the contributors of the Unix history repository [1,2]. Working through the list, the following questions came up. - Lorinda Cherry is credited with diction. But diction.c first appears in 4BSD and 2.10BSD. Did Lorinda Cherry implement it at Berkeley? - Is Chuck Haley listed in the book as the author of tar the same as Charles B. Haley who co-authored V7 usr/doc/{regen,security,setup}? He appears to have worked both at Bell labs (tar, usr/doc/*) and at Berkeley (ex, Pascal). Is this correct? - Andrew Koenig is credited with varargs. This is a four-line header file in V7. Did he actually write it? - Ted Dolotta is credited with the mm macros, but the document "Typing Documents with MM is written by by D. W. Smith and E. M. Piskorik. Did its authors only write the documentation? Did Ted Dolotta also write mmcheck? Also, I'm missing the login identifiers for the following people. If anyone remembers them, please send me a note.

> From: Peter Jeremy <peter(a)rulingia.com> > Why were the original read(2) and write(2) system calls written to > offer synchronous I/O only? A very interesting question (to me, particularly, see below). I don't think any of the Unix papers answer this question? > It's relatively easy to create synchronous I/O functions given > asynchronous I/O primitives but it's impossible to do the opposite. Indeed, and I've seen operating systems (e.g. a real-time PDP-11 OS I worked with a lot called MOS) that did that. I actually did add asynchronous I/O to V6 UNIX, for use with very early Internet networking software being done at MIT (in a user process). Actually, it wasn't just asynchronous, it was _raw_ asynchronous I/O! (The networking device was DMA, and the s/w did DMA directly into the user process' memory.) The code also allowed more than one outstanding I/O request, too. (So the input could be re-enabled on the device ASAP, without having to wake up a process, have it run, do a new read call, etc.) We didn't redo the whole Unix I/O system, to support/use asyn I/O throughout, though; I just kind of warted it onto the side. (IIRC, it notified the user process via a signal that the I/O had completed; the user software then had to do an sgtty() call to get the transfer status, size, etc.) Anyway, back to the original topic: I don't want to speculate (although I could :-); perhaps someone who was around 'back then' can offer some insight? If not, time for speculation! :-) Noel

Synchronous vs Asynchronous IO in Unix

by Peter Jeremy

Why were the original read(2) and write(2) system calls written to offer synchronous I/O only? It's relatively easy to create synchronous I/O functions given asynchronous I/O primitives but it's impossible to do the opposite. Multics (at least) supported asynchronous I/O so the concept wasn't novel. And any multi-tasking kernel has to support asynchronous I/O internally so suitable code exists in the kernel. -- Peter Jeremy

Why root user name?

by Warren Toomey

As I was dropping off to sleep last night, I wondered why the superuser account on Unix is called root. There's a hierarchy of directories and files beginning at the tree root /. There's a hierarchy of processes rooted with init. But there's no hierarchy of users, so why the moniker "root"? Any ideas? Cheers, Warren

Re: [TUHS] Did realloc ever zero the new memory?

by Doug McIlroy

> Did any Unix or Unix like OS ever zero fill on realloc? > On zero fill, I doubt many did that. Many really early on when memory > was small. This sparks rminiscence. When I wrote an allocation strategy somewhat more sophisticated than the original alloc(), I introduced realloc() and changed the error return from -1 to the honest pointer value 0. The latter change compelled a new name; "malloc" has been with us ever since. To keep the per-byte cost of allocation low, malloc stuck with alloc's nonzeroing policy. The minimal extra code to handle calls that triggered sbrk had the startling property that five passes through the arena might be required in some cases--not exactly scalable to giant virtual address spaces! It's odd that the later introduction of calloc() as a zeroing malloc() has never been complemented by a similar variant of realloc(). > Am I the only one that remembers realloc() being buggy on some systems? I've never met a particular realloc() bug, but realloc does inherit the portability bug that Posix baked into malloc(). Rob Pike and I requested that malloc(0) be required to return a pointer distinct from any live pointer. Posix instead allowed an undefined choice between that behavior and an error return, confounding it with the out-of-memory indication. Maybe it's time to right the wrong and retire "malloc". The name "alloc" might be recycled for it. It could also clear memory and obsolete calloc(). Doug

Re: [TUHS] Did realloc ever zero the new memory?

by Norman Wilson

I've used realloc a lot, and never run into bugs. Maybe I've just been lucky, or maybe it's that I probably didn't use it that much until the latter 1980s, and then more with pukka Doug malloc code than with the stuff floating around elsewhere. Never mind that sometime around 1995 I found a subtle bug in the pukka Doug malloc (not realloc): arena blew up badly when presented with a certain pattern of alternating small and large allocs and frees, produced by a pukka Brian awk regression test. I had a lot of (genuine) fun tracking that down, writing some low-level tools to extract the malloc and free calls and sizes and then a simulator in (what else?) awk to test different fixes. Oh, for the days when UNIX was that simple. I've never heard before of a belief that the new memory belonging to realloc is always cleared, except in conjunction with the utterly- mistaken belief that that's true of malloc as well. I don't think it was ever promised to be true, though it was probably true by accident just often enough (just as often as with malloc) to fool the careless. Norman Wilson Toronto ON

V6, V7, Ultrix-11, RT-11 (V4, V5.3, V5.7), RSTS/E (V7, V10.1-L), RSX-11/M+, DSM-11 (kill it with fire)? All of the above?" Cheers, Christian -- Christian M. Gauger-Cosgrove STCKON08DS0 Contact information available upon request. ______________________________________________________________ GreenKeys mailing list Home: http://mailman.qth.net/mailman/listinfo/greenkeys Help: http://mailman.qth.net/mmfaq.htm Post: mailto:GreenKeys@mailman.qth.net 2002-to-present greenkeys archive: http://mailman.qth.net/pipermail/greenkeys/ 1998-to-2001 greenkeys archive: http://mailman.qth.net/archive/greenkeys/greenkeys.html Randy Guttery's 2001-to-2009 GreenKeys Search Tool: http://comcents.com/tty/greenkeyssearch.html This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Ah hah! My stray memory of `Not War?' must date from my TOPS-10 days. I can't find a trace of the string `love' anywhere in any of the make sources in Kirk's multi-CD compendium of historic BSD, so it certainly can't have been from there. Norman Wilson Toronto ON
