Re: 3.3 to 4.5 remote upgrade possible?

2002-03-05 Thread Matthew D. Fuller


On Mon, Mar 04, 2002 at 11:03:47PM -0500 I heard the voice of
Jim Durham, and lo! it spake thus:
 
 Is this Mission Impossible? I have no one at the site that can do this.
 
 If I say make installworld is the whole thing going to come to a 
 grinding halt?

When I did a 2.2.8-STABLE to 4.3-STABLE upgrade, I ended having to do it
in one broken-up step.

First (and the only sane way, IMO) is to do the buildworld on a 4.x
system; get all those lib conflicts and crap out of the picture.  Then I
installed the 4.x kernel, did the necessary frobbing (installing loader,
re-disklabel -B'ing, sd-da renames in /var with mknod, etc), booted up
the 4.x kernel, THEN did the installworld, mergemaster, reboot.

Some issues I found:
- Some apps (portmap in particular) caused no end of trouble when the 2.2
  app ran under the 4 kernel.  Like, kernel-panic type trouble.
- Device renamings are a bitch.

In theory, a 3-4 upgrade should be easier than this, since you don't I
think need to do any device renaming, which solves a bunch of my problems
right off.  I'd still be pretty leery about doing it remotely, though.

Btw, mpeg4ip did not compile here, 4.4 R,  saw it on Linux.

Extending loader(8) for loading kerels/modules split across several disks

2002-03-05 Thread Maxim Sobolev


Hi folks,

Please review attached patch, which adds long overdue feature to our
loader(8), allowing it to load sequence of files as  a single object.
This should allow us to lift 1.44M limit on compressed kernel for the
installation diskette. Please note, that to use this feature to load
gzip-compressed objects you need to split the object first and then
compress each piece individually, not compress first and then split
already compressed file. Therefore tight fitting of each piece to the
1.44M limit could be a little tricky, but not impossible. Other way
around is to use kgzip(8) utility to compress kernel and then split it
into pieces 1.44M each.

If there are no objections I would like to commit it ASAP, so that our
RE team is able to use this feature in the forthcoming 5.0-DP1
release.

Any feedback is appreciated.

-Maxim

Invitation letter from the Organisation Committee of the First World Congress of Future Science and Culture

2002-03-05 Thread Dr Guihua Li

Dear Sir/Madam,

Many
of us who came to work in the sciences or similar areas did so because we wanted
to explore the unknown and gain more knowledge and ultimately make this world a
better place. It is undoubtedly
true that modern science has brought immense benefits to humanity but also
encountered many unsolved questions and problems including environmental
pollution.

Perhaps it is now time for a different approach: Falun Dafa takes a holistic view of life
and the universe. It builds on the insights of modern science and combines them
with the insights from ancient Chinese science and culture. We, scientists who
understand Falun Dafa, invite you to participate in the First World Congress of
Future Science and Culture that will be held at Cambridge on March
9th and 10th of 2002. This congress will see state of the
art research in this field and serve as a forum for discussing how these new
ideas could exert a profound influence on the future science and culture of
humankind.

Renowned specialists and professors in diverse academic
disciplines from many different parts of the world will be participating. A schedule for March 9th is attached. On
March 10 we will be holding an informal discussion session at which participants
at the conference can raise issues with the speakers.

We do hope that you will be
able to find the time to attend.
Please let us know if you have any questions.

Yours sincerely,

Dr Guihua Li

Re: cannot get more than 32 PTYs in 4.4-RELEASE

2002-03-05 Thread Paul Halliday


On Mon, 4 Mar 2002, Patrick Thomas wrote:


 In my kernel, I have:

Not sure if the above steps are actually required. Actually, neither
matter.  I duplicated your steps anyway, and was greeted with the same
messages.

However,

 In my /dev directory, I have used `sh MAKEDEV` to make all 256 /dev/pty
 files.  They are all there, and all have correct major/minor numbers.  I
 know I won't be using all 256 of them, but I just made them all anyway.

I believe the above steps are wrong, looking at /dev/MAKEDEV:

pty*)
class=`expr $i : 'pty\(.*\)'`
case $class in
0) offset=0 name=p;;
1) offset=32 name=q;;
2) offset=64 name=r;;
3) offset=96 name=s;;

interestingly enough the command ./MAKEDEV pty3 will create (as
indicated) heh.. I was assuming too much, something is screwy here.

*confused*

it actually only created 64 terminals. Added the line:

4) offset=192 name=t;;

~# ./MAKEDEV pty4  kill -HUP 1

interesting, now I have 96, but can only use 64. Reboot..



Anyone care to take over?



 In /etc/ptys, I didn't change anything, because all 256 pty entries are
 ALREADY in there:

 # Pseudo Terminals
 ttyp0 nonenetwork
 ttyp1 nonenetwork
 ...
 ttySu nonenetwork
 ttySv nonenetwork

 So those are all there.

 I have used `sysctl -a | grep maxuser` to verify that maxusers is indeed
 128.

 BUT - if I log on via ssh and start screen, and start 31 new screen
 windows, then nobody else can log on to the system - I cannot create any
 more screen windows AND nobody else can ssh in - the machine has run out
 of ptys.

 I use `fstat` to inquire, and I am maxed out at exactly 32 ptys.

 SO THE question is, why am I stuck at 32 ptys ?  I have done it all -
 everything that is in any doc or news post, and everything I was told to
 do here and on -hackers, and yet I am still stuck at 32 !!!

 Please tell me the secret lore for getting more than 32 ptys in
 4.4-RELEASE.


 thanks,

 PT

C vs C++

2002-03-05 Thread Eugene L. Vorokov


Hello,

I have a small problem. I work for software development company and
write daemons and console tools for Unix. My boss wants everything
to be written in C++, because he thinks C++ is cool. I prefer C
for such tasks, but I cannot really put good arguments of why and
where C++ can be worse than C. I know many of you prefer C too.
Can you please explain some disadvantages of C++ comparing to C ?
Is it slower, does it produce less effective code, why is it like
that, etc ... or please direct me to some articles where this can
be explained.

I apologize for the offtopic whenever it happens, but this issue
really pisses me off now.

Regards,
Eugene

You are probably using an out of date kernel module. Use ls -l
/modules to check the modules were all installed at the same time
as the kernel.  If you are uing the trafcount module from ports
then you will need to recompile that also.

(You should be able to use kldstat to check which modules are
loaded.)
