It starts to work, but not yet correctly. Glyphs are truncated. Developed on Windows XP. Are you planning on using FreeType in this?

This slowdown is very small, especially when comparing with other "Hack of Doom". I just want to see, is it the only raison d'être of that old hack or not. Aleksey Bragin wrote: > Why so, Dmitry?

Sound code cleanup and structuring
by Andrew Greenwood 24 Feb '09

24 Feb '09

Hi, As you're all probably aware, myself and janderwald are in the process of working on sound. I thought I'd give a brief update on this, but I also need some feedback on the location of the various sound components in our tree as I think it needs a little reorganisation. At present, I am focusing on the user-mode portion of sound support, with the goal of getting NT4 audio drivers working (legacy Sound Blaster cards etc.) while janderwald is getting newer style WDM audio drivers up and running. I don't want to duplicate code, hence I have been intentionally developing some helper libraries that can be easily reused. Think of them as dedicated abstractions of the various Windows APIs with a dedicated purpose (sound support.) The components involved or which are planned are: - Common library for user-mode side of sound support - Helper library specifically for NT4 device sound support (device "discovery" etc.) - sndblst.dll, mmdrv.dll and wdmaud.drv user-mode DLLs (making use of the above two components, slight variation in functionality for each - Windows 3.1 used to use the equivalent of these as the actual drivers, hence why there are multiple.) - Kernel-mode common library for NT4 style sound drivers - Sound Blaster library (to be shared between sndblst.sys and PortCls implementation) - UART401 library (to be shared between mpu401.sys and PortCls implementation) - Kernel Streaming API - Kernel Streaming components - Port Class driver At the moment I have a few things dotted around a "sound" directory within "include/reactos" I also have some stuff in our "lib" directory (the helpers I wrote) Kernel streaming related components seem to be spread around various places in drivers/wdm and drivers/ksfilter My attempts so far at NT4 drivers are still sat in drivers/multimedia Basically, I want to try and structure this better. I don't think sndblst.dll/mmdrv.dll/wdmaud.drv belong in dll/win32, and I'm wondering if my helper libraries for sound should sit next to the relevant components directory-wise. Or are they fine being in "lib"? They're only used for sound components. Finally, does anyone object to me removing the entire of the drivers/multimedia tree as nothing in there works at all? I wrote most of the code there, there is some redundant code from the very early ReactOS days in "sound", I can leave that if it's really needed. I want to start implementing sndblst.sys properly so I want to clean up a bit first, but thought I'd ask first before I do anything further. Andrew

Hacking Application and Testing ReactOS
by James Tabor 23 Feb '09

23 Feb '09

Hi All! When did this start? Why are we hacking application to work with ReactOS? I see in change 39703 has gone from one kernel call to three. Performance? We need to fix the real problem and it is a very old one too.... SetWindowPos is very broken. Placing bandaids over a bullet wound is not going to fix the problem. Patching around it too! Remember adding hax on top of other hax rant I've posted over the years. Creates more problems and these are still the problems we are having now. Applications must work on other target systems first prior to working with ReactOS. TaskMgr must work on the target system first! Evgeniy Boltik changes are based on good research but testing the changes after is lacking. Evgeniy! Collect and create your test suite of application and test them! AbiWord, FF, ReactOS apps and others that are known to work before your changes. Once you get into a rhythm of testing it becomes easier... Thanks, James

SVN server maintenance and upgrade
by Aleksey Bragin 21 Feb '09

21 Feb '09

Hi, we have put our efforts today to upgrade the SVN server machine, which now runs Subversion 1.5.1, and do some routine maintenance like recompressing the reactos repository, reconfiguring everything, etc. As a result, some total (not even readonly access) downtime happened, however it was only slightly more than a couple of hours, so hopefully noone's suffered too much. Now it runs stable, and better than before. Enjoy. Thanks to Franz, Colin and Christoph for helping with setting up and transferring the server. Their help is greatly appreciated. WBR, Aleksey Bragin.
