-<p>Windows has a concept of <i>hooks</i> that allow an application to monitor -the system for various events that might occur. For example, you can use -the <tt>WH_MOUSE</tt> hook to intercept mouse messages before they're -normally processed. Vitaliy Margolen noticed a problem last week with -Wine's implementation:</p> -<quote who="Vitaliy Margolen"><p> - Trying to track down the problem with our DInput implementation I found -some interesting stuff - our global hooks don't work correctly because -hook callbacks are never called if event is generated in the different -thread. I don't think this is a revelation to number of people who knew -that before. But how do we fix it? +<topic>Multimedia</topic> +<p>Wine has a lot of audio drivers, but some of them don't get used +very often and might not work at all. This week Joachim Förster +posted a problem about the low-latency audio server +<a href="http://jackit.sourceforge.net/">JACK</a>: +<quote who="Joachim Forster"><p> + +some days ago I sent some mails to the wine-users list. My problem: the +JACK output driver of wine does not work => wine segfaults; and the OSS +output driver does not work, too. Windows Media Player (used for +testing) says, it cannot find the audio hardware. +</p><p> +Since then, nobody on the wine-users list had any idea what could be +wrong, so now I am posting this here: +</p><p> +I am new to this list and just wanted to ask a question regarding Wine +and JACK: +</p><p> +I'm running JACK as my sound daemon and today I installed Wine (from the +APT-Repository). I setup my .wine directory with the help of winetools. +So far everything works fine, except sound output (tested with wmplayer +and a simple wav file). So I selected "jack" as Audio driver. </p><p> -Here is what I dug up so far: -<ol> -<li> Installing global hook we setting it as WINEVENT_INCONTEXT while msdn - and tests indicate that it qualifies as WINEVENT_OUTOFCONTEXT instead. - Unless of course we don't want to call post_win_event in step 5 and go - to step 6 instead.</li> -<li> All HW mouse messages start here: - <ul><a href="http://source.winehq.org/source/dlls/x11drv/mouse.c#L191"> - http://source.winehq.org/source/dlls/x11drv/mouse.c#L191</a></ul> - From looking at it I assume that all the HW mouse hooks should be - handled by HOOK_CallHooks function. This is because there are no code - related to hooks in send_message server call.</li> -<li> First thing that HOOK_CallHooks does is calling HOOK_IsHooked with - checks only current thread for installed hooks. So this is first place - that is wrong. Let's comment that check out for now. I think we need - to move that check farther down, after the call to server.</li> -<li> We call start_hook_chain - <a href="http://source.winehq.org/source/server/hook.c#L468"> - http://source.winehq.org/source/server/hook.c#L468</a> - to start hook callback chain. There we call get_first_valid_hook on local - and then global if no local hooks exist. But there again we check for - <a href="http://source.winehq.org/source/server/hook.c#L211"> - http://source.winehq.org/source/server/hook.c#L211</a> - the hook callback thread being local (which is again not the case for global - hooks). This is problem #2.</li> -<li> Now we have post_win_event of but right before it we hitting an assert - so this is not the right way?</li> -<li> Say we returned with success and back to HOOK_CallHooks that now tries - to call MSG_SendInternalMessageTimeout. Which for some reason fails to - deliver message to our global hook.</li> -</ol> +But wine segfaults with wmplayer as soon as opening the wav file: +<ul><code> +$ wine .wine/c/Programme/Windows\ Media\ Player/mplayer2.exe<br /> +fixme:process:SetProcessPriorityBoost (0xffffffff,1): stub<br /> +fixme:powermgnt:SetThreadExecutionState (0x2): stub, harmless.<br /> +fixme:powermgnt:SetThreadExecutionState (0x80000000): stub, harmless.<br /> +This sound card's driver does not support direct access<br /> +The (slower) DirectSound HEL mode will be used instead.<br /> +Segmentation fault</code></ul> </p><p> - -So my question is to anyone who knows. What is the proper way to deliver -these messages to global hooks that are in a different thread/process? -</p></quote> - -<p>Rolf Kalbermatter added to it:</p> -<quote who="Rolf Kalbermatter"><p> - - -Just an observation I did in a Windows program running under WinXP. -Not sure if this is related somehow but it seems quite like the opposite -of what you describe here although with windows message hooks. +I started qjackctl to see what the JACK says: +<ul><code> +20:01:39.052 Audio connection graph change.<br /> +20:01:39.136 Audio connection change.<br /> +20:01:39.314 XRUN callback (1).<br /> +20:01:39.317 Audio connection graph change.</code></ul> </p><p> -I had a program that was hooking window messages for a particular window. -When using SendMessage from the same thread as in which the Windows message -loop was running (doesn't make much sense of course but it was just for -testing purposes) I could not receive any events above WM_USER, lower -events did seem to get received properly though. When placing SendMessage -in a different thread the events did come through. +So, I assume there was an "connection" established between Wine and JACK? </p><p> -Not exactly sure yet what this is all about but message handling and -especially hooking in Windows for sure can be a tricky business.</p></quote> - -<p>Alexandre replied and outlined what was going on:</p> -<quote who="Alexandre Julliard"><p> -That's because the new win event code changed the meaning of the -thread field, and the low-level hooks haven't been updated for it. Try -something like <a href="http://www.winehq.com/pipermail/wine-devel/2006-January/044439.html">this</a>. +Does anybody know something about this problem? Tell me if I have to +provide more (log/debug) output etc. ... +</p><p> +I am running Ubuntu Breezy (breezy kernel 2.6.12-10-686). +</p><p> +PS: Direct output to ALSA works (with jackd not running). </p></quote>

-It does work thank you. The only question I have : does that cover -WINEVENT_OUTOFCONTEXT hooks too? + +Yes. Great, thank you very much :-) ! </p><p> -I'm working on a test to test hooks. Hopefully there will be a way to -test it. +BTW: I had to set "Hardware Acceleration" to "Emulation" (instead of +"Full", but did not try other levels) to make mplayer2.exe play all my +test wave files _right_. </p><p> -And it looks like we will have to rethink our DInput - the game still -doesn't work. It seems that the thread which acquired mouse doesn't -have a message loop. -</p></quote> +I used the c:/Windows/Media/*.wav files. And the strange thing was, that +mplayer2.exe (with "Full") played some of them right and others wrong (= +sounds like sampling freq. (transformation) issue).</p></quote>
-<p>Regarding Vitaliy's question about WINEEVENT_OUTOFCONTEXT hooks, -Alexandre asked if he knew they were broken. Vitaliy replied that he -was just asking.</p> +<p>Eric submitted another patch to wine-patches later to address the issue.</p> </section> <section title="Overriding Executables With Winecfg"
