Subject:unpipeIt'seasy for a process to insert a new process intoapipelineeither upstream or down unpipe

by Doug McIlroy

It's easy for a process to insert a new process into a pipeline either upstrean or downstream. Was there ever a flavor of Unix in which a process could excise itselfa from a pipeline without breaking the pipeline? Doug

At the time its only competitor was RSTS-11, and to a lesser extent RSX-11D and RSX-11M (all DEC systems). It saw CP/M vanish, MS-DOS come and go, NT tried to challenge it, and even Windows hasn't beaten it. It spawned Linux, which Billy Gates regarded as a serious threat ("any box running Linux is not running Windows") and even tried a smear campaign against it.

Re: [TUHS] Happy birthday, core dumped

by Doug McIlroy

They pitched a PDP-10 for a similar reason--hardware to build a bigger Unix on. When a small pot of end-of-year money appeared, they took a PDP-11 instead--serendipitously, because university folks started proving this elegant system on cheap hardware in many projects in small labs, which they never could have done had the system existed on a PDP-10 mainframe. While upper management did not directly cause Unix to be built, their decisions to abandon Multics and not to buy a PDP-10 were notable causes for its creation and spread.

It was probably a fixed-head disk (RS11 or RS04); can't exactly stick a different pack in! :-) Probably the DEC OS's only used it for swapping or something, since they were both relatively small - 512KB. (Speaking of RS11's: the first PDP-11 I used - an 11/20 running RSTS - had a grand total disk storage of _one_ RS11!) And speaking of putting file systems on them: I recently wrote this command for V6 called 'si' which allowed me (among many other interesting things) to watch the contents of the disk buffer(s). It turns out that even with other packs mounted, the buffer is almost always completely full of blocks from the root device; it makes plain the value of having the root on a _really_ fast disk. I don't know if that usage pattern is because /bin is there, or because pipes get created on the root, or what. When I get up the energy I'll move /bin to another drive (yeah, yeah, I know - good way to lose and create a systen that won't boot, so I'll actually make a _copy_ of /bin and mount it _over_ the original /bin - probably a host of interesting errors there, e.g. if a process has the old /bin as its current dir), and see what the cache contents look like then.

Tree of late BSD releases

by Diomidis Spinellis

For reconstructing Unix history on a single repository [1], I'd need to represent the branches, merges, and chronological sequence of the late BSD releases (after 4.3). However, I've found on the internet some conflicting and simplistic information, so I'd welcome your input on how to straighten things up. First, consider this widely reproduced BSD family tree [2]. It has 4.4BSD-Encumbered derive from a line that includes Net/1, which was freely redistributable. Wouldn't it be clearer to create two branches, one with distributions free of AT&T code (4.3 BSD Net/1, 4.3 BSD Net/2, 4.4 BSD Lite1, 4.4 BSD Lite2) and one with full distributions (4.4 BSD, ...)? On which side would Tahoe and Reno stand? Also, the same tree [2] shows 4.4 BSD having as its ancestor 4.3 BSD Net/2, whereas another tree depicted on Wikipedia [3] has shows 4.4 BSD and 4.3 BSD Net/2 having as their ancestor 4.3 BSD Reno. What's the correct genealogy? Finally, I have a conflict with release dates. Wikipedia gives the following dates for Tahoe and Net/1 [4]: 4.3 BSD Tahoe June 1988 4.3 BSD Net/1 June 1989 However, looking at time-stamp of the newest files available under the corresponding directories in the CSRG CD-ROMs [5] I find the opposite order: cd2/net.1/sendmail/src/util.c 1989-01-01 12:15:58 cd2/4.3tahoe/usr/src/sys/tahoevba/vx.c 1989-05-23 13:47:43 What's the actual time sequence, and what's the corresponding genealogy? [1] https://github.com/dspinellis/unix-history-repo [2] http://ftp.netbsd.org/pub/NetBSD/NetBSD-current/src/share/misc/bsd-family-t… [3] https://en.wikipedia.org/wiki/File:Unix_history-simple.svg [4] https://en.wikipedia.org/wiki/Berkeley_Software_Distribution [5] https://www.mckusick.com/csrg/ Many thanks, Diomidis Spinellis PS Thank you all for the help you've provided so far.

Re: [TUHS] Happy birthday, core dumped

by Norman Wilson

Interesting - what's your source? It was also my understanding they used the -7 'because it was there' but that they had pitched for a PDP-10, which had TOPS-10. ====== I think Doug's source is in the class `personal observation.' He was there at the time; Ken and Dennis's department head, if I've got it right. Remember that Bell Labs had just disengaged itself from the Multics project. The interest in a new OS sprang partly from the desire to have a comfortable multi-user system now that Multics was no longer available. That's why the DEC operating systems of the time, which were (as I understand it) simple single-user monitors, didn't fill the bill. The character of the players matters too: remember that Ken is the guy who one night sat down to write a Fortran compiler because real systems have Fortran, and ended up inventing B instead. I've read that there was indeed a pitch to buy a PDP-10; that there was some complicated plan to lower the effective cost; and that upper management (not Doug) turned it down because `Bell Labs doesn't do business that way.' I think I got that from Dennis's retrospective paper, published in the 1984 all-UNIX issue of the Bell Labs Techical Journal, a must-read (along with the late-1970s all-UNIX issue of BSTJ) for anyone on this list.

4.1BSD Networking

by Cory Smelosky

Hello all, recent subscriber to this list...but some might recognise me. I'm currently fighting (and mostly succeeding) with getting a pure 4.3BSD-Tahoe install rolling in a VAX simulator (all my tape drives are currently nonfunctional or I'd fire up a real II or III). Still in the middle of compiling (I know there are easier ways...but I like the feeling of doing it purely "from scratch"...feels more historically accurate). Anyways, while waiting for the compile I ended up with a working 4.1c installation and I began poking around its source tree (I also did a little bit of poking at the CSRG discs). I stumbled upon the fact 4.1c supports the DMC (which SIMH git now emulates!) and I see it's also still in src/old on some versions of 4.3 (I wonder if it'll still build...). Looking at the source is immensely confusing...does anyone have any knowledge/notes from the time period/documentation that will help me with my little experiment in archaic networking? I might just be tired...but the berknet configuration doesn't make a whole lot of sense to me. (There's also the fact my grasp of C is minimal). -- Cory Smelosky http://gewt.net Personal stuff http://gimme-sympathy.org Projects

Doug McIlroy: > Does anyone know why [Computing Systems] folded? Arnold Skeeve: ISTR that they simply ran out of content; they weren't getting enough submissions to keep it going, and journal production isn't an inexpensive undertaking. ====== That's what I remember too, though there may also have been insufficient interest from the members. The front matter in the last issue suggests that. Computing Systems was published from Winter 1988 to Fall 1996. (More years than I'd have guessed, even looking at the physical journals on my shelf; it was a quarterly.) It would probably not have lasted much longer no matter what, as the USENIX community was likely in the forefront of putting papers online on the World-Wide Web. USENIX now makes all their conference papers available online, free to anyone, except that only those registered for a conference can read them before the conference actually happens. That's not a bad substitute for a journal, I suppose. Norman Wilson Toronto ON
