emacsclient with emacs-23.0.60

emacsclient with emacs-23.0.60

[Thierry Volpiatto]

Hi,

i have my $EDITOR set to emacsclient (in a script) and i am using
emacs-23.0.60-unicode.

I have a problem with emacsclient:

when i start emacsclient from a terminal , no problem it tell me i have
to do C-x # when done: thats normal.
when i launch emacsclient from an external program (python tk) it open
the file wanted but differently:
emacs say: buffer 'my_file' still as clients; kill it ? (y or n)

if i say yes, 
it kill the buffer but the windows stay here and it's not
an external windows of my emacs session, it seem to be a clone of my
emacs session: if i do C-x 5 0 in my emacs session (the original one,
where emacs server is launched) it kill this session.

if i say no,
i can edit my file, save it but i can't quit this windows without
killing all my emacs (i am not prompted to C-x #)
With emacs23.0.50 (non unicode) on another machine and with emacsclient
launched from the same program (a python agenda/planner) emacsclient
works normally with C-x # to finish emacsclient

So the problem is when i start emacsclient from an external program and
after i want to finish it, it kill the emacs session where the server
have been launched.

It seem to do that only with graphic programs:
when i call emacs client with mutt for example it work normally.

If some body have an idea ? or the same problem ?

Thank you

There are more server- commands once the server has started. One of  
them is server-edit. Does this help?

Thanks for your answer,

server-edit is binded to C-x # .
Normally emacsclient notify that in minibuffer but here no;
  
when i do that in the new windows created by $EDITOR (alias emacsclient)
called by my python app emacs tell me there is no emacs server.
but there is! emacsclient work fine from any term and also from a remote
computer with emacsclient -t

I think the new windows created when i call emacsclient is a clone of my
emacs session , because when i want to close it with C-x c or from my
emacs session with C-x 5 0 it close all emacs (without saving that is bad)

So i don't know if there is a new feature of emacs that i don't
understand or it's a bug.

I reply to myself just to say i have switched to emacs-23.0.50 
(non unicode) and emacsclient work again with my app python.

So i think it's a bug of emacs-23.0.60-unicode

psvn.el also work only partially with this version of emacs :
ediff don't work.

Bad for my eyes! xft is so nice!

I cannot confirm! Both work. What I can assume is that some of your  
personal settings are incorrect. Do you see different behaviour when  
launching

	emacs-23.0.60 -Q -f server-start &

 From which date is the code for GNU Emacs-23.0.60?

As I experienced and also stated by one of previous posts,
the issue related to the emacsclient is gone, if you start
the emacs and the server within from a terminal or xterm.
If you type that line in an xterm, you won't see that
behaviour.  But if you launch it from `dmenu[1]', you'll see
that the emacsclient is not working properly.  Presumably,
it's related to the handling of the environment variables?

No, it's not working better like that, 
emacsclient is working fine when i start it from any term or remote term
but is not working only in this special case:

when i call it from my python app throught the mailcap module.

For svn, ediff work fine with emacs-23.0.50 but don't work on 23.0.60
but may be i miss some thing.
It seem svn don't recognize my environment variable $EDITOR (emacsclient)

I launch emacs-server from my .emacs with (server-start). 
Which environment variables are you thinking about ?

Could be there is something with missing environment variables ...

A simple 'strings `which emacsclient`' reveals:

	ALTERNATE_EDITOR
	DISPLAY
	EMACS_SERVER_FILE
	HOME
	LOGNAME
	TERM
	USER

USER, LOGNAME, DISPLAY are important. Can you launch a simple shell  
script instead of emacsclient that just records the environment  
variables it sees inside Python? Like:

	#!<path to your login shell>
	env | sort -o /tmp/EnvironmentAsSeenFromWithinPython$$

Then compare this with that which a regular shell or GNU Emacs'  
*shell* buffer has.

And in the next round: make that shell script replace the utility  
that would be determined by the mailcap file – I have no idea why you  
mention this, because mailcap names a "proxy" to handle a particular  
data type. Does this "proxy" application launch and for which data  
type does it launch? Or do you mean that you have extended mailcap to  
use emacsclient for some data type(s)? Then it would be easy to  
substitute "emacsclient" with "shell script name" for a test and all  
is done.

I did that and i have two files now:
 - One done with replacing emacsclient by the command line you gave me 
   in my script that is launched as $EDITOR in .mailcap 

 - One with your command line runned in the shell of emacs (not eshell)

I have 2 list of environnement variable but it's don't "talk me a lot!"
I attach them, if you have the time to have a look.
6915==>from my python app
7619==>from shell

The problem is now repeated in all my emacs-cvs (22 and 23)
The problem with "svn-status-ediff-with-revision" also
I think the problem is related to my $EDITOR value but i am not sure.
Only the "emacs22 no cvs" is working.

And added to that, (it's a bad day :) ) since the update of my system
this morning , /su::/... with tramp is not working anymore
(authentification fail)
I think it's from the update of pwdb and pam the problem come. 

Thank you for your help, i try hard to understand your advices!!

There are some obvious differences, of which the first two express  
that some Bash RC file produces them:

	DISPLAY is a bit different (it could make a difference with more  
than one screen)
	INFOPATH and PATH have each an element more

a second shell launched from a third shell launched from a fourth  
shell launched from a login shell? I can't see an obvious cause for  
the failures, except that level of "complexity."

easily "upgrade" to version 23.0.60 since this one does not compile  
in Mac OS X 10.4.10 – temacs fails. "Working around" this by

I think you're right, i have a problem with my shells:
when i call at boot the last command of the tty1, instead of having
startx (thats the last command of this term normally) i have all the
last command i done in my urxvt term ( x term)
when i call svn-status for ediff files it tell me:
no program or file named $EDITOR
So there is a confusion in my env variable and the name of my term since 
an update of my system.
I keep trying to find what is wrong .
The bug i had with su with tramp is a bug of tramp itself, it have been
corrected , the patch is here: 
http://lists.gnu.org/archive/html/tramp-devel/2007-10/msg00064.html
Thank you for all your advices.

Is there no way to make the PC boot into the "X11 level?" I.e.  
setting initdefault in /etc/inittab to 5 via 'sudo telinit 5' should  
allow you to log-in at a graphical tool which, when you succeed, will  
launch X11 for you at once.

When the file ~/.bash_login exists then ~/.profile won't be read/ 
executed by bash when using a login shell.
An interactive bash reads/executes ~/.bashrc.


Yesterday, in MET, it worked again to compile GNU Emacs 23.0.60 on  
Mac OS X – and its emacsclient works well!

When you work in a real X11 environment and not in GNUstep/OPENSTEP  
or Mac OS X, then X11 should inherit from your login shell the whole  
environment.

In most (all?) shells you can distinguish between interactive  
($PROMPT present) and non-interactive ($PROMPT not present) use.  
Additionally you can run shells as login shells, which makes them  
read/load another resource script (~/.login etc.). So you can control  
which environment variables will be valid in which situation.

Xterm can be launched with a login (-ls) and with a non-login shell  
(+ls, default behaviour). See also loginShell X resource.

To compare the environment variables set: ``env | sort -o file1´´.  
Then diff the files. (There are too many shells around and some, like  
bash, are much too complicated in case of resource scripts.)


GNU Emacs saves the environment it inherits in the variable process- 
environment (in a long unsorted list like ``"TERM=dumb"  
"HOST=here.local" "GROUP=pete" "LOGNAME=pete" ...´´ in which getenv  
searches). For debugging it can help when one augments the shell's RC  
files (resource scripts) with statements to output messages (echo,  
printf something like "Hi, it's me, RC file so-and-so starting", and  
also when leaving) or to save them in files (in /tmp for example)  
with unique names (using for example $$ in the resource script when  
building the file name, or recent date). Anyway, it will pretty time  
consuming. Another, sometimes faster option, is to use a "trace"  
facility to watch a programme (or two: GNU and emacsclient) working.  
The trace implementations can be set to filter particular "data  
streams" (network io, disk io, dynamic/shared libraries, ...).

Thanks Peter for help,
i keep trying to see what's wrong,
checking what's different from one emacs version to the other.
