Oh.. I get it.. I thought you meant NT vs Unix. I guess we may close the subject then :) (I'm a usermode guy mostly, and I puke when I have to write for Linux, since they don't have things like GDI, et cetera.)

Bad architecture ? Compared to Linux ? I refute that on the strongest. F.ex: Linux lacks, even to this day, a unified graphics API like GDI (X-Windows notwithstanding), and window manager. Instead they have a plethora of disparate kludges and hacks on top of X-Windows, all more or less cumbersome to use. The API flora of the Windows architecture should, by rights, make Linux programmers green with envy ;-) (Why do you think the WinE project was born in the first place?) Best Regards // Neo

ReactOS versioning
by Love Nystrom 21 May '16

21 May '16

Excuse my extremely late thoughts on this issue.. Perhaps they're moot already. Regarding pt.3 in Timo's very succinct post (a year ago), I see a possibility in a "proxy" scheme as follows.. The "standard" dlls knows the 6.x APIS, while implementing the "base" 5.2 functions, and forward newer APIs incrementally to versional "add-on" dlls. This ought to avoid bloat, both RAM and disk-wise. // "Proxy" kernel32.dll knows APIs up to X.Y kernel32.dll!Some52API_1 :: Built-in // "Base" APIs kernel32.dll!Some60API_2 -> rkernel32_60.dll // Additional APIs only kernel32.dll!Some61API_3 -> rkernel32_61.dll // Additional APIs only For DLL_PROCESS_ATTACH the ROS loader could provide kernel32.dll et.al. with version info, gleaned from the exe, through lpvReserved, in case version specific init is needed. In case the exe has no version info, fall back to 5.2. Dito for the other "standard" dlls. Was this what you had in mind? (PS. I'm not privvy to the mechanics of SxS, but I think they replace the entire dlls, wholesale.. right?)

I would suggest to unite some core DLLs into "ros-kernelbase.dll" or something and gdi32/user32 into ros-win32.dll and export all functions from those, using forwarder DLLs through SxS. At the same time we should reorganize the code, organizing it the way that MS API sets do it. And also move the stuff out of the "dlls" folder into "win32core" or something. > 3.

I don't believe I said 'let's add random exports to our DLLs'. In fact, in your old thread, I was totally FOR your idea, I even wrote that the only sane way of doing it is with the app compat work.

The project doesn't have to be hard-coded to NT5. For example, I am building a UEFI loader/bootmgr based on Windows 10, because 2003 doesn't boot on UEFI systems. That being said, I don't see any good reason for us not to still mainly focus on 2003 for the kernel. The kernel is NOT what's preventing apps from working, or hardware from working. What's preventing that from working is: 1) Lacking user-mode APIs, and in some cases Rtl APIs (sure, implement Win 10 ones!) 2) Lacking hardware support for things like UEFI (I'm working on it), AHCI (we have a student working on it), USB 3 (someone can implement this...but USB 2 barely works), etc..etc..etc.. Find me a single device driver that *only* works on NT 6... Server 2003 is still a support MS OS, so by definition there's still drivers for it.

Regarding r71352 and SubGit
by Colin Finck 18 May '16

18 May '16

Hello all, As most of you know, I have been busy setting up a two-way Git mirror of our ReactOS repository using SubGit. Testing was done in the recent weeks by multiple people using a sandbox repository and the results looked pretty well. Therefore, SubGit was considered ready for prime time and I started a first import of our ReactOS repository. The only problem with this: Even without mirroring branches, the Git repository became a 5.5GB monster (from the 750MB of our current git-svn mirror). This size was totally not clonable as shown in testing. The proposed solution: Git offers a garbage cleaner using "git gc --aggressive". And hell yeah, it reduced the size to a nice 500MB repo. While that optimization was running and SubGit was not syncing, two revisions were committed: r71350 and r71351. Without expecting any problems, I resumed SubGit mirroring and then things started to get weird: Apparently, SubGit totally lost traction of the SVN repository and instead of syncing the two new revisions, it committed one in r71352 that _replaces_ trunk by r71349. This is one of the worst commits possible, as it forces SVN clients to redownload everything when updating their working copies. Even more, it shows me that a clear separation of permissions for the SVN Server and SubGit isn't sufficient. SubGit can and actually did harm to our repository this way. This is exactly what I was warned of and what now happened... I'm sure everybody can understand that I cannot continue with the SubGit installation under these circumstances. We cannot put our repository at risk, especially now that we're in the mid of GSoC. This way, SubGit has definitely shown that it's not ready for our repository. I deeply apologize for this trouble and especially to the critics who remained right. And of course to Hermes, whose name SubGit abused for making the guilty commit. Right now, I'm restoring the repository to r71351 using backups and "svnadmin dump". This effectively erases r71352 from SVN history. As r71352 was only online for 10 minutes, I believe it's better to get rid of that commit in SVN history rather than having everyone suffer from it. Again, I deeply apologize! With best regards, Colin
