Re: [Winmm/winealsa] Don't use asynchronous callbacks in dsound any more
by Eric Pouech 26 Dec '06

26 Dec '06

Maarten, nice work on Alsa (which is definitively needed !!) a couple of comments: - I know the winmm code (and drivers) is crippled by bad synchronisation tricks (like cleaning a field in a structure to signal a thread). This is bad (TM). So I'd suggest using here a real synchronisation object. - I wonder if it's a good idea to create another thread for this... but before merging all existing drivers' threads into a single one, I'd suggest using the fd oriented functions & poll (see snd_pcm_poll_descriptors and friends) instead of snd_pcm_wait, that'll ease up the future work.

window managment bug
by Clinton Stimpson 26 Dec '06

26 Dec '06

Does bug #6006 fall under window management? When buttons are turned invisible, the invalidated area in the parent window is not repainted, so it looks like the button is still there. Also, there's two invisible buttons that seem to repaint themselves when the parent window resizes, clicking on them does nothing. Any ideas where I can go to track this down? Thanks, Clinton

Re: oleaut32: preliminary support for VT_DISPATCH as parameters to VarAdd (and other 2-operand operations) (try 3)
by Alexandre Julliard 26 Dec '06

a_villacis(a)palosanto.com writes: > This is another attempt to add IDispatch support to several 2-operand > functions. Now the macro was removed and the VT_DISPATCH handling was > copied to every affected function. Thanks, it's better that way. Still, it seems to me you don't always clean the variants properly, you should do some sort of "goto end" in all cases instead of simply returning. Also renaming the function parameters in most cases is not necessary. I'd also suggest to do a separate patch for each function, especially since in some functions a bit of restructuring will be needed to cleanup properly on error. -- Alexandre Julliard julliard(a)winehq.org

more meaningful traces?
by Lei Zhang 26 Dec '06

26 Dec '06

Hi, I noticed several files in dlls/winmm have a getMessage() function to translate message numbers to message names. This is extremely helpful for debug traces, where one can immediately see the name of the messages sent, instead of wondering what 0x105 is. So my question is, why is winmm the only component translating its message? Is there some downside to having message names in the traces? Happy Holidays! - Lei

kernel32 (profile.c): current section and key implementation
by Claudio Fontana 25 Dec '06

25 Dec '06

Hello all, I posted previously a patch to wine-patches here: http://www.winehq.org/pipermail/wine-patches/2006-December/034022.html However, I now understand that although it solves the issue I had with the specific program, the change is incomplete, since in several other places, sections and keys are only considered meaningful when not equal to the empty string. In the Microsoft implementation, the unnamed section is valid, as are zero length keys. Thus, I think a broader scope change is required. Before I start working on a new patch, do you acknowledge that the current implementation is incorrect, and a patch fixing it by not requiring name[0] to be != '\0' is likely to be accepted? (btw, I've noticed you switched to git, so I will be using that instead now). Thanks, Claudio Fontana

Re: ntdll: Added stubs for the Rtl*GenericTable* functions
by Vitaliy Margolen 25 Dec '06

25 Dec '06

Is there are any reason why do you need this functions at all? According to ddk they are part of "Installable File System Drivers". This is a kernel level thing only and no user app should use these routines. Especially stabbing them won't do you any good if something actually using them. But that something has no place to run in Wine yet. Vitaliy.
