Sorry, I was not precise enough.
I prepared arrays in the initiated data segment:
This program cannot be compiled:

uintptr scnd[] = {nil, nil, frst, [1]};

}
...because of:

Hi all,
I tried some artificial example for Plan9 compiler (5c)...
This code is compiled without any problem:
uintptr frst[] = {nil, nil, nil, nil, nil};
uintptr scnd[] = {nil, nil, frst, [0]};
But this one fails:
uintptr frst[] = {nil, nil, nil, nil, nil};
uintptr scnd[] = {nil, nil, frst,

Hi all,
I am trying a very simple 'go' program under Plan9 (both 386 and ARM):
package main
import (
"fmt"
"net"
"time"
)
func main() {
laddr, err := net.ResolveUDPAddr("udp", ":6000")
if err != nil {
fmt.Println("laddr: ", err)
}
raddr, err := net.ResolveUDPAddr("udp", "cpx61.tk8.lan:6000")

Another stupid question - sorry for that ;)...
9pi has about 1,7GB plan9 partition size.
On my 8GB SD card the rest is unused...
Is there a way how to extended plan9 partition to use

Hi all,
I am trying to compile Go 1.4.3 on my Raspberry Pi following David's

Hello everyone,

However during the booting it has a problem with nvram each time:

If I choose to install plan9, I get a result shown in the attached

If I choose to just boot (not install), it gets stuck after

Try to play with AHCI settings in BIOS.

Hi all,
I am trying such simple program:

Hi cinap,
hangup(cfd);/* hangup connection, fd stays valid but i/o will error */
thank you for your explanation and help.
Going to use 'hangup' function. ;)
Pavel
another way to implement these kinds of timeouts is
alarm(), see sleep(2).
Yes, I know.
But it was just a simplified example to explain my real need:
- 'receiver' process
- another 'sender' process, which should have a possibility to close the
TCP connection, and relase 'receiver' from read()
OTOH, 'hangup' approach does not work in UDP.
It means, read() is not finished... :(

interesting, that might be worth implementing.
Maybe.
the alternative would be to send the reading process a note to
interrupt the blocking syscall.
Actually, it my 'plan B'... ;)
the closer proc should just send the note and not close the fd.
and the reader proc should close the fd
the changes to implement udp hangup are trivial tho:

Hi all,
I tried very simple program on native Plan9:
#include u.h
#include libc.h
void
main(int, char**)
{
int afd, lfd;
char adir[NETPATHLEN], ldir[NETPATHLEN];
afd = announce(tcp!*!20540, adir);

lfd = listen(adir, ldir);
if (lfd 0)
sysfatal(listen: %r);
Hi Sergey,
It seems, you do it incorrectly :) dial(2) has an exact example if using
announce/listen/accept functions.
I do exactly what I need. ;)
The sequence announce/listen/accept is very well known to me.
But I need both possibilities:
- accept incoming connection
- reject incoming

In fact.
Without having further information about your setup I

Read the whole thread, but I think my linked message has the answer.
Do you start keyfs before listen in your cpurc?
Yes, it was 1st thing I checked...

Hi Stevie,
you were right, I missed one point during the server
installation/configuration:
I forgot 'auth/changeuser bootes'... :(
Now 'auth/debug' works well, sorry for a noise.
And thank you.

Hi all,
I am fighting with configuration of '9pccpuf' server.
I have configured user 'bootes' as a hostowner.

I can 'srv' such server from another Plan9 terminal ('9pcf') as user
which version of hg are you using?
...from contrib - bichued/hg
i'm pretty sure that jeff's version use ape/psh to execute
commands, but not positive. it must use psh to be posix-y.
Ah, where is it available?
Pavel
https://bitbucket.org/jas/cpython
you can pull hg directly from the mainline.
Well, I am a little bit confused...
1. Is is a new 'python' interpretter implementation? What is a difference
from 'bichued/python'?
2. Is my original problem with mercurial caused by 'hg' or 'python' on
Plan9?

Hi all,
I am using native Plan9.
I tried to create a remote Mercurial repository via 'ssh':

Hi Steven,
For the most part, using HTTP/S repositories will give you the best bang
for the proverbial buck.
I see. In fact I tried to create and use Mercurial repository via 'ssh' and
'ftp' (via ftpfs) and none of them works.
Pavel
It seems I do not fully understand the discussion about ssh...
When I manually make this command (what 'hg' does)...
ssh xxx.yyy.zzz hg init test
...the result is:
bash: hg: Command not found...
When I manually modify it...
ssh xxx.yyy.zzz 'hg init test'
...the result is...

I discovered another interesting feature in my tests:
If 'fork' exceeds nproc value, kernel panics.
If 'fork' reaches the available memory limit, it is blocked until some
memory is released (e.g. by the finish of some process).

Hi Steven,
conf.nproc = 100 + ((conf.npage*BY2PG)/MB)*5;

conf.nproc *= 3;

In general, you will find that 2000 is the highest allowable due to
limits imposed by proc.c.

Hi all,
I would like to know whether there is any hard (based on CPU architecture)
limit of maximal number of processes in Plan9 on Intel or ARM.
I do not think the soft limit like the lack of memory... ;)
Thanks in advance for any hint.
