Patch: DSound: PhaseCancel subtracts secondary from primary
Hi wine-devs, I have sent this patch to wine-patches, but it appears to have been dropped. I have resent it with some additional explanantion (below). Is there anything I've done wrong / anything I should do in order to get this patch accepted? Any advice would be appreciated, Thanks Davin PS. How long should I wait for a patch to be accepted before I assume it's been dropped? ---- Hi, This is my first ever wine patch. I have been doing work on DSound as discussed on wine-devel with some very promising results (see the discussion there). As a result I have a large number of changes which I intend to provide a series of patches for. This is one is probably the most trivial fix and is largely unrelated to the other fixes. But if you look at the code for a while as I have you can see that it's obviously correct - the existing implementation of PhaseCancel inverts the original waveform; with this patch it doesn't. Please consider accepting. Thanks, - Davin Changelog: DSound: PhaseCancel subtracts secondary buffer from primary buffer, not the other way around. Davin McCall davmac(a)davmac.org

You sent the first patch yesterday, a Sunday. Alexandre doesn't usually check in patches on a Sunday, or the weekend for the most part. Since people do send in patches over the weekend, you just need to let Alexandre some time to catch up =) So I'd say a few days is probably enough. If something is needs to improved, someone will probably speak up or you can ask like you did.

BTW, do you think this error with D2 is related to this bug you found? This is from wine plus your other patch. See previous message. err:dsound:DSOUND_PhaseCancel length not a multiple of block size, len = 3026, block size = 4 Thanks, Jesse
No - that's an unrelated problem. The DSOUND_PhaseCancel method is being requested to cancel a length which isn't an integer number of frames. Probably it is being called from somewhere which isn't doing correct length translation of secondary to primary buffer (ie primary_length = secondary_length / secondary_blocksize * primary_blocksize. The secondary blocksize may be smaller if it is a mono buffer, for instance. That calculation is oversimplified also, because sample rates between the buffers may vary and this needs to be taken into account. I plan to keep looking at DSound issues but I like to do these things progressively (i.e. get a few patches submitted and accepted, then do some more) - otherwise the change ends up being huge, and to break it up is a lot of work. BTW, thanks for the note re patch acceptance. I had noticed some patches which had been sent in after mine had been accepted, so I guess I got worried - but you're right, it's too soon (though it is in fact Tuesday in my time zone :-)) Davin On Mon, 31 Oct 2005 18:07:08 -0700 Jesse Allen <the3dfxdude(a)gmail.com> wrote:
