[TUHS] m68k SVR2 on Perq (was: web site detailing Apple's mc68k UNIX, A/UX)

by Roger Willcocks

Incidentally, the Unisoft m68k port of SVR2 at the core of A/UX was also ported to the Perq-5 in 1986/1987, to create the Crosfield Studio 9500. Perq had just folded, but a core group of ex-Perq employees worked with a team from the UK company Crosfield Electronics to take the machine (which at that time existed only as a wire-wrap prototype) through to production. I was a member of that team and I have fond memories of sitting in a basement office in Pittsburgh surrounded by kernel listings (with a very puzzled look on my face). Just a small footnote in Unix history... -- Roger

is learn(1) free now?

by Kenneth Stailey

Hi, When 4.4BSD-lite was released one of the 4.4BSD encumbered things that was cut was the online courseware program, learn(1). When I purchased my copy of _The CSRG Archives_ CDROM set I was told in E-mail by McKusick that I did not need to sign any license agreements. I am assuming that this is due to Caldera proclaiming that V32 sources and binaries could be redistributed by the public legally. In the CDROM set is a fully encumbered 4.4BSD source tree which includes the learn(1) source code. I spent a few hours last night porting it to NetBSD and FreeBSD and tightening up a few bits like gets() vs. fgets(). I haven't finished and have yet to distributed the results. I also have yet to get the vi lesson data which the source code that I do have says came on a separate user-contributed tape. I got here because I have newbies in my life now and I need UNIX online courseware. The only thing I could find in the FreeBSD ports tree was something called vilearn. I'm wondering about distributing the results of my porting effort once it matures enough to be worth doing so. Thanks, Ken __________________________________ Do you Yahoo!?

Apologies if this has been answered before, but I noticed that there are AT&T copyright notices in the kernel sources for Unix Edition 5, but they were removed in Edition 6. You can still see the comment blocks for the notices in Edition 6, but the notices themselves have been removed. Does anyone have the history on this? I noticed that USL registered Editions 5, 6, 7 and 32V in 1992. I would assume that Editions 4 and earlier are free and clear because, prior to 1978, registration was a requirement for protection. Further, since USL waited longer than 5 years to register the copyrights for 5, 6, 7 and 32V, these may be free and clear as well. As I understand it, Editions 7 and 32V could have had copyright protection without registration since they were released after 1978. However, because they lacked copyright notices when released, they may very well be considered public domain. It was not until 1989 that the requirement for including copyright notices was dropped.

To be precise, that license covers 32-bit 32V UNIX 16 bit UNIX Versions 1, 2, 3, 4, 5, 6, 7 with specific exclusion of System III and System V and successors. That is why source code for the Seventh Edition system (for example) is openly accessibly on the TUHS web server. Among those whose dog work produced first a hobbyist-specific per-person license, then the current BSD-like license, was Warren Toomey, who manages that web server and this mailing list. I don't think it will give him a swollen head (or a wooden leg) to thank him now and then, and I do so here. Long-time readers know all that, but those who have joined us recently might not.

Re: [TUHS] question about mkfs(8) and stdio

Line buffering was a Berkeley innovation. stdout became line-buffered by default (when it is a terminal) in 4.0BSD. 4.2BSD added setlinebuf(3) to allow people to make stdout or stderr line-buffered when they want to. 4.3BSD extended it to work on any stream, not just stdout or stderr. > If you look at an old BSD mkfs for cylinder-group style file systems (not 7th > Ed filesystems) Ahmm, you call that old?

I use 4.3BSD-* systems every day and have been for the past several years, and you can take my word for it that on all 4.3BSD-* systems, including Quasijarus, plain 4.3, and Ultrix the alternate superblock list output from mkfs/newfs appears one line at a time on the tty. > At some point I thought "SysV must have broke this" I'm curious, where does SysV fit into this? It's the wonderful 4.2BSD filesystem a BSD-only thing that Missed'em-five people treated as a satanic manifestation? > since newfs would print out > a complete row of superblock numbers at once with a big delay between the rows That's exactly what it does. BTW mkfs = newfs. mkfs was/is the original UNIX filesystem creator. It was almost completely rewritten in 4.2BSD to create the new filesystems. At the same time the newfs program was written as a user- friendly front-end to mkfs (it merely exec'ed mkfs with a bunch of options). The situation remained in 4.3. In 4.3-Tahoe/Quasijarus mkfs.c and newfs.c are compiled and linked into one binary called newfs, CSRG was forced to do this in order to support disk labels. MS

question about mkfs(8) and stdio

by Kenneth Stailey

Did stdio buffering change over time? If you look at an old BSD mkfs for cylinder-group style file systems (not 7th Ed filesystems) you will see the super block backup loop does not fflush(stdio) between printf()s printf("super-block backups (for fsck -b#) at:"); for (cylno = 0; cylno < sblock.fs_ncg; cylno++) { initcg(cylno); if (cylno % 10 == 0) printf("\n"); printf(" %d,", fsbtodb(&sblock, cgsblock(&sblock, cylno))); } but I have memories that the superblocks were printed out one at a time as if fflush(stdout) was called between them rather than one line at a time with line-buffered stdio. At some point I thought "SysV must have broke this" since newfs would print out a complete row of superblock numbers at once with a big delay between the rows rather than each superblock number with a short delay between each number. But when I go searching the oldest BSD code has no fflush(stdout) the way modern FreeBSD does: for (cylno = 0; cylno < sblock.fs_ncg; cylno++) { initcg(cylno, utime); if (mfs) continue; j = snprintf(tmpbuf, sizeof(tmpbuf), " %ld%s", fsbtodb(&sblock, cgsblock(&sblock, cylno)), cylno < (sblock.fs_ncg-1) ? "," : "" ); if (i + j >= width) { printf("\n"); i = 0; } i += j; printf("%s", tmpbuf); fflush(stdout); } Did stdio buffering change over time so that line buffering became the default?
