Anyone knows why the majority of windowed applications launched from an
emacs shell doesn't show until the shell buffer is killed? [MSWindows]

Try M-x shell <RET> notepad

Doesn't show anything on the computers I've tried until C-x k

Can you reproduce this starting from "emacs -Q" at the command line?

What version of Emacs is it? Please paste the text from M-x 
report-emacs-bug.

I have no problem reproducing this with an unpatched Emacs from 2009-01-04.

Strange, I couldn't reproduce this when I first tried, but now I can 
reproduce it every time on Emacs 21.3, 22.3 and CVS trunk.

Perhaps it was a recent OS patch that caused this behaviour. It does not 
even seem to be linked to the fact that the shell window is hidden, as 
changing w32-start-process-show-window does not improve the problem.

Is the problem still reproducible?

  M-x shell <RET>
  notepad <RET>

works as expected for me.

It works as expected for me now on Vista with CVS trunk. But I don't think
this was the configuration I reproduced it on originally.

Well, IMHO it does not make much sense to keep the bug open if we
cannot reproduce it. We can reopen it if it happens again.

Please leave it open until we've had a chance to try on systems where it
was known to fail.

OK, though I don't see in the thread any specific system where it was
known to fail. Not a lot of detail in the reports.

I haven't tried the 4 CR trick outlined in the original posting but this is  
an issue that I have to deal with all the time. It stops me from doing all  
my work in Emacs.

This also reproduces on the latest released patched EmacsW32 distribution  
running Emacs 23.2/

Does it help to invoke GUI programs via "start", like this:

  d:\foo> start notepad

> This also reproduces on the latest released patched EmacsW32 distribution  
> running Emacs 23.2/

I can see it in the current development version as well.

I played with this, and here are my observations.  Hopefully, someone
who knows more than I do about the startup process of a GUI
application could make some sense out of it.

 . The behavior is not entirely repeatable.  Sometimes I need 3 RETs,
   sometimes 4, and sometimes just 1.

 . It looks like the program that is invoked is in some limbo state
   inside early stages of its startup code, until you hit enough RETs.
   Process Explorer shows no threads for such a program.  PsList does
   show one thread, but it is waiting for something.  Here's an
   example with notepad:

    Tid Pri    Cswtch            State     User Time  Kernel Time  Elapsed Time
   2872   8        14   Wait:Executive   0:00:00.000  0:00:00.000  0:00:05.354

 . Each time I hit RET, notepad seems to do a few more things in its
   startup.  Process Explorer shows more and more handles being open.
   I show below the list of handles after each RET.  Note that the
   desktop (WinSta0) is only opened after one RET.  Another noteworthy
   fact is that when started from shell-mode, GUI applications have 3
   pipes open -- those are the 3 standard handles they inherited from
   Emacs via cmd.exe.

 . I also tried with runemacs.exe, and I see the same pattern: it
   takes several RETs for it to make through its works, at which point
   it spawns emacs.exe and exits.

 . Invoking GUI programs through the "start" command works as
   expected: the program opens its window immediately.

   Here's the list of handles open by notepad just after the invocation:

*** I didn't even think of that. I use that for a service that I am testing
but didn't think to use it for non-service exes. I'll give that a shot when
I am back in office tomorrow.  Thanks for the idea!

I can confirm that both the start command as well as hitting RET 3-4 times
both work for me. Interesting side note: If the app brings up a dialog that
requires input then displays a main window, both require the 3-4 RETs. In my
case, I am using P4V.

1) In Emacs cmd shell type: p4v
2) Hit RET 3 times to display the connection dialog.
3) Enter connection information and hit OK

Note that nothing happens...

4) Hit RET 3 more times in the cmd shell
5) P4V main UI shows up.

bug#1819: Anyone knows why the majority of windowed proggies launched from an emacs shell doesn't show until the shell buffer is killed? [MSWindows]

[dhruva]

Hello,
 I did some further testing. Not conclusive though but enough to give good leads.

shell>notepad
You do not see the notepad window showing up (as reported)

shell>[return]
shell>[return]
shell>[return]
shell>[return]

And you see the notepad window coming up after exactly 4 CR presses! Somewhere, it is expecting CRLF combinations I guess.. some comint?

For records, this works as expected:
(comint-exec (current-buffer) "notepad" "notepad.exe" nil nil)
