[Bug 13420] New: Hang on first keypress

http://bugs.winehq.org/show_bug.cgi?id=13420

Summary: Hang on first keypress
           Product: Wine
           Version: 1.0-rc2
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Start a simple app (i.e. winecfg or regedit).
Everything seems to work fine.

Press any key (even shift is ok): the app
hangs completely - no redraw, nothing.

Can be kill with CTRL-C though.

First noticed with .rc1, still present in .rc2.
Last version tested without that bug: .58

Ciao.

Not critical. Please run a regression test as described here:

Well, not critical for you but for me, Wine is
completely unusable - in other words, a blocker.

For the record, I'm using old-style xmodmap
keyboard settings - xkb is disabled.

My keyboard layout is non-standard but even
with xorg's standard layout the app hangs.

Regarding the "regression testing":

I don't have the necessary tools to
compile wine.  I'm using prebuild rpm's
for suse.

As requested, the log of starting notepad with

to release it.  Then killed notepad with CTRL-C.

What distros are you using? What xorg versions (X -version)?
Wine not even receiving the event - should see something like this:

trace:event:call_event_handler KeyPress for hwnd/window 0x10024/4600005
trace:key:X11DRV_KeyEvent type 2, window 4600005, state 0x0010, keycode 0x0032
trace:key:X11DRV_KeyEvent nbyte = 0, status 0x3
trace:key:X11DRV_KeyEvent KeyPress : keysym=FFE1 (Shift_L), # of chars=0 / ""

Are you using any extra input modules (xim, xcim)?

--- Comment #8 from Flob Flobber   2008-05-27 01:16:45 ---
SuSE 9.3 with Xorg 7.1.99.2.

No input methods.
No Xkb.
No deadkeys.
German keyboard but non-standard layout.

Just checked: there is no KeyEvent.  The only message
that still comes when the app is stuck is this when
I enter/leave the window with the mouse:

| trace:event:call_event_handler PropertyNotify for hwnd/window 0x10020/4d
| trace:event:call_event_handler PropertyNotify for hwnd/window 0x10020/4d
| trace:event:process_events processed 2 events

No expose or motion events any more nor a ClientMessage
for the window-close button.

Ciao.

Can you try an older Wine release, say 0.9.55 or even older? There there a lot
of changes recently in XIM support, that may has broken something for you.

I've got two setups on identical servers: one is working fine with 0.9.57, the
other one had 0.9.48 running and was upgraded to 1.0. Now applications hang on
first keypress (didn't touch the first server). I tried .57 on the second
server as well, but .48 was the last working version. 
Both servers run CentOS 4 with kernel 2.6.9-67 and KDE in a VNC session.

Phew, regression testing is quite lengthy :) However, I ran into a compile
error:
| wrap.c: In function `ME_WrapTextParagraph':
| wrap.c:356: error: syntax error before "wc"

The last version successfully compiled was 0.9.52.88-something, now the first
lines from "git log" are:
| commit 28cc0f9e690a675aa00b0ccc02b442fcf8a819ea
| Author: Eric Pouech 
| Date:   Tue Jan 1 22:04:40 2008 +0100
|    richedit: Fix the para computation when zoom is used.

"git describe" gives:
| wine-0.9.52-102-g28cc0f9

Should I mark this bisection as bad and continue?

Are you running wine inside vnc? If so, this is probably a duplicate of bug
11822.

Could be a duplicate for what I have here (two ident. servers over VNC, and
PS/2 keyboard on the client, no kbd on the servers, also see #12). Flob, how
about you? 
I'll continue the regresssion tomorrow, and try what's suggested in #26 bug
#11822.
Little side note: Is it okay to take part, although I'm not the reporter? I'm
willing to help as best as I can.

Indeed, the vnc bug looks similar.

But... here wine inside Xvnc (v6.8.2) works fine.

# wine notepad
press any key in notepad - hang (btw, not a CPU hog
hang - system is 100% idle).

but

# Xvnc :1 &
# vncviewer :1 &
# DISPLAY=:1 wine notepad

works.  The only noticable effect is that terminating
notepad takes exceptionally long.  After 3-4 seconds
this message appears:

| fixme:event:wait_for_withdrawn_state window 0x20028/a00013 wait timed out
| fixme:event:wait_for_withdrawn_state window 0x10024/a00005 wait timed out

Hmm... I think I found something.  After these two lines I thought
"maybe this is due to a missing window manager..."  So I started
twm and bang, the problem occurs - notepad hangs on first keypress.
When I terminate twm, notepad runs fine again.  Same with windowmaker.

Summing up: wine notepad within an Xvnc runs fine but takes long
to terminate (with error message) as long as no window manager is
running.  Either with twm or windowmaker the hang occures.

Btw, my regular window manager is icewm.

More info: if I enable "Emulate a virtual desktop" the
problem vanishes - notepad works.

Maybe related: If I disable all options in "winecfg.Graphics.
Window_Options" the wine window never gets focus and thus
no key event at all.

Ciao.

Thanks; most likely that's yet another XIM deadlock bug. You can try to comment
out the XInitThreads call in x11drv_main.c to confirm this.

Okay, works in 0.9.57, if the call is commented out:
| if (!(env = getenv("XMODIFIERS")) || !*env)  /* ... */
|     /*if (!XInitThreads())*/ ERR( "XInitThreads failed, trouble ahead\n" );

Can use it as a switch between working/non-working :)

Yeah, with XMODIFIERS I can toggle between
working and non-working.

Without XMODIFIERS: wine notepad -> hang
With XMODIFIERS: XMODIFIERS=1 wine notepad -> no hang

But something's still fishy:

no window-manager: wine notepad -> no hang
with twm: wine notepad -> hang

both times without XMODIFIERS.
