[9fans] P9p on Fedora 12

[9fans] P9p on Fedora 12

[Pavel Klinkovsky]

Hi all,

I use p9p on my older Linux (Fedora 10).
I tried to compile and run it on my new PC with Fedora 12, but without
success:

[pavel]$ 9term rc
usage: devdraw (don't run  directly)
9term: initdraw: muxrpc: unexpected eof

Any idea?

Thanks.

Pavel

I've not rebuilt on my mac in a while.  I'll try again today, but I don't
like to run Fedora in general.  I typically like archlinux these days, as
it's small and fairly sane.

Strange, I tried to compile p9p on the latest (9.10) Ubuntu, and no
success too.

Re: [9fans] P9p on Fedora 12

[Pavel Klinkovsky]

Sorry, I was not precise enough.
The compilation itself succeeds but I cannot rung 9term:

[pavel]$ 9term rc
usage: devdraw (don't run  directly)
9term: initdraw: muxrpc: unexpected eof

I must do something wrong but I do not know what...?

Pavel

Re: [9fans] P9p on Fedora 12

[Gabriel Díaz]

hello

i can reproduce that with:

gdiaz@m9363:~/plan9/src/cmd/
devdraw$ echo $DISPLAY

gdiaz@m9363:~/plan9/src/cmd/devdraw$ 9term
9term: initdraw: muxrpc: unexpected eof
gdiaz@m9363:~/plan9/src/cmd/devdraw$ 

so, can you use other programs X programs?
do you have a DISPLAY 
variable? 
are you trying to execute 9term using ssh x11 forwarding?

may be devdraw does not use the x11 library which does the trick with ssh? i think ssh does not set the display variable, and still the normal X 
programs works due some trickery on a x11 proxy library :?

That is true.
But muxrpc error is also there. A consequence?

[pavel]$ 9term rc
usage: devdraw (don't run  directly)
9term: initdraw: muxrpc: unexpected eof

dennis was right.  print statements are often the best way
to debug a problem.

why don't you temporarly hack devdraw with something
like the following in main before ARGBEGIN

fprint(2, "devdraw args: "
for(int i = 0; i < argc; i+)
	fprint(2, "%s ", argv[i]);
fprint(2, "\n");

perhaps this output will give you some more ideas.
if you're a bit unfamiliar with the code (or just don't
remember), the second best debugging tool is grep.
i don't immediately recall, but i would imagine that
libdraw is starting devdraw.

i suspect a well-executed pincer manover with print
and grep will quickly rout this bug.

Re: [9fans] P9p on Fedora 12

[fgergo]

I haven't found any resolution to Pavel's original problem, hence this email.

Same problem here:
x86, FC12: INSTALL went smooth (no errors in install.log), but all of
the devdraw based programs stopped with the reported error.

After installing the packages libX11-devel, libXt-devel and
libXext-devel, INSTALL produced the expected result, all programs work
correctly.

I noticed that, the references to LOCAL.config and nowsys in
install(1) are somehow not clear to me. I could not find out how
nowsys was built instead of reporting the missing X11 libraries and I
couldn't find LOCAL.config either.

Re: [9fans] P9p on Fedora 12

[erik quanstrom]

while you're at it, more new p9p bugs.  after "upgrading"
my linux box,
1.  <insert> in acme on a string like /usr/quanstro/src/
inserts another / for each keypress.
2.  passwords are echoed by 9term
3.  9term still rechoes its input:
	; echo 9term
	echo 9term
	9term

I don't know what this means.
Acme has no <insert>.
I haven't seen this.

> 2.  passwords are echoed by 9term
> 3.  9term still rechoes its input:

These are variants of the same bug.
I've been seeing it on Ubuntu Lucid too.
If you or anyone would like to hunt down
what's changed in the tty settings and
how to fix it, I'd gladly accept a patch.
When I first saw it I spent a while running
stty commands but to no avail, so I've
been putting up with the echoing, but I'd
love to get it fixed.

Thanks.

oh, sure it does.

/mnt/term/usr/quanstro/plan9/src/cmd/acme/text.c:792,799
	switch(r){
	case 0x06:	/* ^F: complete */
	case Kins:
		rp = textcomplete(t);
		if(rp == nil)

oddly¸ i see that the arm port has exactly the same bug.

sorry, i take it back.  drawterm also has the same bug.

there are several timing bugs, but often what i see
is the +Errors window opening up with just a /
in the body.  (but sometimes the / is inserted in
the original space.)  Undo in +Errors yields the normal
completion list.  texttype() really does get
Kins then '/'.

it turns out that x helpfully yields this if i hold down
the insert key
	<insert>//////////////////////////////////////////////

x has a brand new bug.

modern linux systems can be a good example of how better can be
the opposite of working.

What works for me is putting 9term in raw mode and then stty -echo.

if you then edit a line, like this
(^ for tick)

	; echo pdq^
	; echo ^pdq
	; echo xyz^pdq
	; echo xyz^pdq<cr>

does it echo xyzpdq or pdqxyz?

i'm guessing the (incorrect) latter.  iirc
i tried this approach on linux and it doesn't
work.

But I swear there used to be a way to make it work
in cooked mode, so that I can edit the command lines
before hitting enter.  On my Mac's 9term, I can still type

echo world

and then mouse to the middle, insert "hello", mouse to
the end, hit enter, and I get "hello world".  But it still
doesn't echo passwords.

Something changed in Lucid but I have no idea what.

Re: [9fans] P9p on Fedora 12

[Skip Tavakkolian]

I gave the wrong mode. If you put 9term in "cooked" mode and stty
-echo then (interacting with rc), the
example below will echo the "xyz".  The "pdq" is placed on the
following line with cursor placed at '^'.
this is identical behavior to a rio window.

cpue% echo xyz
xyz
cpue% ^pdq

% uname -a
Linux ubuntu 2.6.32-24-generic #41-Ubuntu SMP Thu Aug 19 01:12:52 UTC
2010 i686 GNU/Linux
% echo xyz
xyz

Yes but then sudo sh echoes your password.
9term used to be able to figure out the right thing
to do (it polls the tty state at each keystroke)
and no longer does.

Re: [9fans] P9p on Fedora 12

[Charles Forsyth]

in rcinputproc
		s = setecho(sfd, 0);
		if(write(rcfd, pair.s, pair.ns) < 0)
			threadexitsall(nil);
		if(s)
			setecho(sfd, s);

there's a race between setting echo off, writing to rcfd, resetting echo and
the reader of the other side of rcfd. a sleep(1) before if(s) makes it less frequent
because the reader gets to read the data in the right mode.
i haven't really looked at what linux is doing that allows that,
or what changed between revisions.

it's not my observation, it was on a list or issue comment somewhere,
presumably for p9p. i can't find the bookmark.

thanks for this.  sleep(1) helped only rarely,
sleep(10) helps most of the time.  unfortunately
then there's a race between the invoked program
turning off echo and 9term turning it back on.
so "sudo sh" is pretty likely to echo the password
with the sleep in there.

what a mess.

i just submitted some code that should clean up
the mess.  it does active echo cancellation on its
own, instead of trying to coerce the tty into doing it.

the changes also make win behave the same
way as 9term: if you've done "stty echo" then
you can edit with the mouse, but if not, you can't.
so running "su" doesn't show a password anymore
in win, but you can't use the mouse to edit in an
interactive python session.  win some, lose some.

I am sorry I forgot to write the solution here.
As expected, the problem was between my keyboard and chair... ;-)

This was my mistake.
I forgot to install *-devel libraries.

I can confirm that:
- P9p on Fedora 10 does not echo the input,
- P9p on Fedora 12 (13) echoes the input.

Are you using the latest version of 9term?

cd $PLAN9
hg log -l 1 src/cmd/9term

That reminds me, a p9p install in which 9term was not echoing input
under OS X echoes input under slackware. Same source tree, just re-
INSTALLed. I intended to hg up before posting about it, I'll do that
now.

Fixed for me after hg update. (Slackware 13.1, Linux 2.6.35.4)

Delay along the path...
I inserted this report one week ago (before you patched the
problem). :-/

Now it works fine. Thanks.

to get around this, i start up python with a script, py:

#!/bin/rc
PYTHONSTARTUP=$HOME/lib/pythonstartup
cat | python -i $*

where $HOME/lib/pythonstartup holds this, to stop
the secondary prompt getting in the way after leaving hold
mode:

import sys
sys.ps1 = '> '
sys.ps2 = ''
