Debian.org domain
Hi all, I was wondering why the HURD project has no domainname. It seems hurd.org is registered by someone in Istanbul, is he somebody of the HURD people?!? Regards, Daniel De Kok

bcopy
1) Is there any reason bcopy is used in Hurd sources instead of memcpy ? (I have quite old sources here) 2) Is it ok to send patch to change it ?

(I have quite old sources here) Well, I don't know if there is such a reason. Probably Thomas spent too much time in the BSD sources :) But let me point out that bcopy is equivalent to memmove, not memcpy (which doesn't handle overlapping regions). 2) Is it ok to send patch to change it ? I can't answer that for the core developers, however, is there a particular reason beside cosmetic? Of course, if you bother to find out where memcpy is sufficient instead memmove/bcopy, it might be a small performance advantage. Thanks, Marcus PS: Such mails are slightly more appropriate for bug-hurd@gnu.org, where development of the Hurd is discussed rather than the binary distribution. -- `Rhubarb is no Egyptian god.'

Re: Hurd sources distribution
On Tue, May 02, 2000 at 11:02:29PM +0200, Tomasz Wegrzanowski wrote: a) Are Hurd sources diffs available somewhere ? Sorry, my omission. I always try to keep the debian directory uptodate in CVS, and most of the time the rest is unchanged, so I don't package upstream/diff, but only as a single tar file. The very few cases I apply patches I will try to remember to put them somewhere in debian/. Note that I always mention changes explicitly in the debian changelog, so if it doesn't mention anything, nothing changed from CVS. b) Why Hurd sources hasn't been splited ? b1) Linux compiles in half an hour on my machine (under Linux), and Hurd hasn't finished in 10 hours (under Hurd). I suppose Hurd is *much* more memory-consuming (it's 16MB RAM system), or I'm doing something very wrong (most of the time I wasn't looking, so I don't know what was happening), but it make playing with Hurd quite difficult. Yes, the Hurd is somewhat bigger, and the fact that there are pic libraries created as well doesn't make it better. Furthermore, native compilation is always slower than cross compiling from linux (becuase of the general slowiness of the hurd). However, what would a split gain you, except that you have to compile several packages? Maybe when all hurd libraries have versioned symbols a split might become useful. This is something that will be decided by the Hurd core when it becomes interesting. b2) Maximal machine power of Hurd machine is very limited. It supports 1 processor, 1GB partitions, probably not much of other resources (anyone has real numbers), What other resources are there you care about? (If someone has a SMP board, please work on SMP support in GNU Mach! If you can't, send the board over to someone who can :) and compilation should be broken to parts that compiles on maximal supported machine in very reasonable time. It would be more clear which parts of Hurd changed recently, if only these ones changed their version. I should include all changelogs in the package :) b4) dpkg was invented to support many little packages, huge, multi-functional packages aren't very compatible Actually, huge packages which contain related stuff are much easier to handle. For now, please just accept that it is much more convenient for the developers to keep the whole hurd source in single tree, although it might this is not the Most Perfect Thing To Everyone. There is a technical reason, too: The Hurd libraries don't carry versioned symbols (actually, the latest libthreads does), and the soname is not kept uptodate in CVS, so you might get obscure problems if you update only parts of the Hurd and are not careful about it. With split packages, I would end up to spent most of the packaging time in figuring out the correct dependencies, and might still fail. This is not a workable solution. Remember that we are working with development snapshots, as opposed to released version. A tip: Keep the build tree around. When updating the source code, the Makefiles will only build the changed object files, resulting in a much shorter build time. Thanks, Marcus -- `Rhubarb is no Egyptian god.'

re: Re: URLs for new developers 20000418
Hi Jeff, Probably best if you handle it for now. I'm pretty well swamped at work and it may be a month or two before I come up for air again. If you could get me write access that would be great but I will be unable to do anything for awhile. I am registered as a developer at sourceforge.net under the handle cykick. If you could send me some info how to register myself with the hurddocs project at sourceforge.net I'll go ahead and do that. Talk to ya later.

Major GNU/Hurd using report
1)
bash protests that it can't find `mesg' program when I log in
bash is of course right, because there is no `mesg' installed,
and `mesg' is part of sysvinit, so it's corrrect it's not installed
but why does bash need `mesg' ?
2)
Famous I/O problem
I tried to check if VGA registers are the only ones affected
And no, much more are affected
Here's CMOS reporting program
--- start ---
#include mach/machine/pio.h
int main() {
int i,j;
printf (CMOS content report\n\n);
for (i=0;i0x40;i++) {
outb (0x70,i);
j=inb (0x71);
printf (Cell $%d(0x%x) = %d\n,i,i,j);
}
printf (End of Report\n);
return 0;
}
--- end ---
outb is:
#define outb(port, val) \
({ asm volatile(outb %0, %1 : : a ((unsigned char)(val)) , d ((unsigned
short)(port))); })
Therefore there are these possibile reasons, why it is possible to r/w hardware
ports :
- I/O Permision Level is way too low
but asm(pushfl) says IOPL=0 (kernel only)
- user programs run in kernel space
I hope not, no test was done
- Mach gives default permision to every program to use all hardware ports
No test was done yet
3)
I have problems with networking
There is no eth, only loopback should be used
telnet doesn't work
tail of syslog - last two days (there was more than 1 run/day) :
--- start ---
May 2 12:40:41 localhost syslogd: restart
May 2 12:40:41 localhost inetd[29]: ftp/tcp: socket: Translator died
May 2 12:40:41 localhost inetd[29]: finger/tcp: socket: Translator died

May 3 19:04:21 localhost inetd[29]: ident/tcp: socket: Translator died
May 3 19:04:21 localhost inetd[29]: smtp/tcp: socket: Translator died
--- end ---
Every time I `ls -l /servers/socket'
It prints :
`2 - translator died'
(then normal list)
mc says : `file 2 exists but can't be stated'
showtrans says /servers/socket/2 is /hurd/pfinet -i=rfsd
4)
Is there any fatfs translator ?

If this option is not recognised, the translator will die. Try with /hurd/pfinet -i rfsd at the command line and see if it complains. Try without this option. settrans /servers/socket/2 /hurd/pfinet 4) Is there any fatfs translator ? I am currently writing one! It can already list the root directory and stat some files, however, it is hopelessly buggy and no files can be read (I/O error). However, I did only work for a couple of hours on it, so there is hope. I will make the source public in a couple of days, so people can join me. (Need to clear it up before this, and attach proper copyright notices). I only aim at read-only without long file names. Long file names might follow, but I will not be able to implement write support in the near future. However, FAT12/16/32 will be supported. Thanks, Marcus -- `Rhubarb is no Egyptian god.'

gcc3 evaluation platforms
gcc currently defines release criteria for gcc3. See http://gcc.gnu.org/gcc-3.0/criteria.html. For ix86 Debian is proposed as primary evaluation platform. For sparc and alpha, Ben Collins and Chris Chimelis volunteer to evaluate gcc3. Currently we do not have feedback from the other architectures (besides ix86). Please have a look at the debian-toolchain archive for the past discussions, if you consider to evaluate gcc3 for your platform.
