ReactOS Being Rewritten, Gets Wine Infusion

xlotlu writes "ReactOS was meant as a free and open-source operating system, binary-compatible with Microsoft Windows. But after 11 years in development it never reached a satisfactory level of usability. Due to lack of developers, reimplementing the Win32 subsystem proved to be a much too complex task, holding the project back. Given the deficiencies of the current implementation, developer Aleksey Bragin decided to rewrite it from scratch, drawing heavily from the Wine project. Bragin's announcement on the ReactOS mailing list makes a compelling argument for this decision."

    Actually, it does put energy into Wine. Reading quickly, it appears that it implements a shim underneath the win32 support in Wine, bypassing the usual Wine requirement for an X-Server. So they can work on the Wine APIs and both projects benefit.

    If you read the actual post, what this guy is doing makes a lot of sense. He's not re-writing ReactOS from scratch, he's just taking the parts of ReactOS that have worked out reasonably well (the kernel, bootloader, etc.) and tossing the stuff that hasn't worked out so well (the Win32 API subsystem). It just so happens that another project, WINE, did a really impressive job at getting that Win32 API layer implemented, and rather than maintaining two completely independent versions of it, piggybacking off the WINE work should make ReactOS usable relatively soon, and able to run a large number of existing Win32 applications.

    Whether you think ReactOS is a sensible project or not, clearly some people think a complete, Open Source, Windows-compatible OS has some real value, and kudos to them for figuring out how to make that happen, or at least getting very close.

      Wine didn't always have that separation between X and the Win32 API. It took quite some time for the project to reach the point where it would have been feasible to take just the Win32 specific parts and plug them into ReactOS. Specifically, 11 years ago it would have made a lot more sense to design things the way the ReactOS ended up implementing their Win32 layer rather than use use Wine's implementation.

      I've been following both projects for many years (since 1994 or so for Wine) and neither project made the colossal mistakes that people seem to think that they did - it may seem that way in hindsight, but given what was available at the time when the decisions were made, they made perfect sense.

      Wine won out in the marketplace because its design allowed it to get some applications running with relatively little work. Getting every last detail of the Windows platform implemented proved to be very difficult, though. ReactOS promised to offer a way to solve those last niggly details relatively easily, but the need to solve them was pushed so far into the future that nobody found the idea all that exciting. Plus, just getting a usable desktop environment running with ReactOS proved to be a massive undertaking, one that the Wine project didn't have to tackle at all. Add to that the work needed to write drivers for real hardware, a minimal set of tools that you'd need to run ReactOS as your OS, and probably a few hundreds of really important pieces that you would need to get anything done with it, and you're looking at a huge amount of work.

      Even if ReactOS never ends up as a viable desktop OS, I can see a possible future for it as the Windows NT replacement of choice for embedded systems, similar to what FreeDOS ended up.

It won't ever offer the *same* user experience and its not enteded to do so.

    ReactOs on the other hand could feel much more Windows like if implemented in a complete way.

But without some sort of prescience it's impossible to make reliable judgments. That's why all those corporate projects flop; someone in authority makes a judgment about which strategy to pursue and in five years time one or more of their key assumptions is shown to be false and the software is rendered useless.

    Of course, the same thing happens to free software projects as well. The difference however is that the Free Software developmental model tends to result in massive parallelism. Lots of projects fail, some are unexpected successes, and the successes aren't always the ones you'd expect. Think of it as a sort of software Darwinism: lots of projects die out, but the ones that thrive are well adapted to the needs of their userbase.

    Looked at in that way, the lack of central direction in Free Software isn't the flaw that many perceive it to be. It is something to be celebrated.

    If it's based on Wine, why not just put their energy into Wine?

    After having spent some time reading his presentation it seems that they want to avoid the dependency on X Windows that Wine apparently has. Thy main aim is to come up with a bootable version of WINE such that you can avoid the overhead of effectively running two operating systems. They also hope this will allow them to use certain drivers that WINE cannot as they want lower level access to the hardware than X Windows will ever provide.

    Please not I am not an expert on any of this so please do correct me if I am wrong, but I did see some value in their approach since it is rather a lot of work to get Linux install up an running on an old PC if all you want it for is to run a few legacy windows applications and nothing else.

    The idea of getting both groups contributing to the WINE higher level code also does now add to the WINE pool of developers too. This could actually help both projects considerably. So in a way, they are going to be putting their energy into WINE. They are not planning to fork the WINE source, they want to do regular merges into their tree. He quotes that it only takes 30 minutes to to this on a fresh WINE snapshot. It might then take a little longer to fix their code to take into account of changes in WINE but this is still pretty good.

    What killed OS/2 was IBM basically blowing a 1-2 year lead on Chicago, not anything to do with Windows compatibility. IBM simply did not know how to market OS/2 Warp, bumbled around for over a year while Microsoft basically convinced developers to hang on for an operating system that didn't even exist (all those early "screenshots" of Chicago that first showed up in 1993-1994 were in fact artists' renderings). Even Microsoft wasn't really all that ready, as Office 95 was simply a variant of the 16-bit suite with a 32 bit wrapper. What's more, Windows 95 was an absolute horror story reliability-wise compared to OS/2. It was a piece of garbage. But Microsoft won because Microsoft understood the PC marketplace, and IBM had little or no understanding.

    I know some of this because I was working for an IBM VAR at the time, and we saw just how inept IBM was, despite having what was, at the time, an extraordinarily powerful OS, with a powerful scripting language (Rexx), pretty good networking that included a full TCP/IP port, a fast and reliable file system and even it's own GCC port in the EMX system. I've told the story here before, but IBM was so bizarre that when they launched Warp 4, they didn't hand us VARs out OS/2 Warp 4 install CDs, they gave us a fucking movie that you played in a Windows machine. It was pretty much at that point that we figured out IBM had lost the thread of the conversation, and we pretty much abandoned selling OS/2.

    I can feel your point, but Windows feels like that on the surface because of a very well engendered Microsoft principle--backward compatibility.

    The command interpreter that was command.com from the DOS era was integrated into NT5+ as cmd.exe, which many of us know, love, hate, and have thanked for allowing us to continue to run .bat files well into 2010 (even though we really, really should have taken the time to master VBScript). Meanwhile, the more powerful, flexible, and truly modern evolution of that archaic CLI comes in the form of PowerShell, which gives you that bash-like capability and power contained in a CLI that was designed specifically for the Windows platform.

    The primary method to access a partition in windows is certainly via a drive letter, but if you do manage to go past 26 partitions, you'll get "A-A:," A-B:," and so on. Still, you can actually access these volumes in a more "modern" fashion by using their volume names directly (e.g. \\?\Volume{volume-guid-goes-here}) and not just the mount points they've been exposed on, or you could always expose the same volumes as a folder on an already mounted NTFS volume as well.

    The thing is that many of the gripes more technical folks have had about Windows over the last decade have been solved in one way or another, but the problem is that since all of the old methods continue to work, there's little to no incentive for users (including systems admins, IT pros, programmers, and so on) to change our behavior, especially when we already know how to solve a given problem, irrespective of whether or not our chosen method is actually the most elegant solution.

    I have to admit though, if I hadn't been forced to manipulate Linux based OS's in the ways that are required to get work done, particularly with respect to volume management, I probably wouldn't know about any of this stuff in Windows in the first place :P

    I would suggest that what Bragin has in mind, as described by the summary and article, is a full open source operating system that would be "binary compatible" with Windows. He is "drawing heavily from Wine" in re-writing ReactOS, which had never reached fruition in the past.

    There's a big difference between an Windows-compatible opensource OS and Wine. I can imagine a lot of people who have rejected the notion of installing another open source OS and then installing Wine in order to run Windows programs would be more interested in an OS that just ran Windows programs. For the casual user, installing Linux and then configuring Wine in order to run their Windows programs is not trivial. Imagine just having to install Ubuntu and then being able to install and run your Windows programs on top of it. That would seriously shake up the OS landscape, no?

    I have no idea whether or not Bragin will be able to pull this off. I can imagine the obstacles are nearly insurmountable. But if he manages to do it, it'll change the world for a lot of personal computer users who are not fully satisfied with the current OS offerings.

    Why has not one of the highly-rated comments addressed the most important point thus far? One of the critical features of ReactOS is not that it runs Win32 programs (which most operating systems can do to a reasonable degree via wine) but that it runs NT drivers. This is a huge deal: you get full hardware compatibility with anything that has a driver for Windows, which means pretty nearly anything at all. Consider, for example, ndiswrapper (Linux kernel module that provides an NT5 Network Driver Interface for the Linux kernel); with ndiswrapper you can use most network devices in Linux even if there's no native driver, because you can just download a driver intended for XP and it works fine.

    Now, take that same idea, and extend it to every driver, 100% compatiblity. It's not Linux underneath, of course - the driver stack has to be engineered for exact NT compatibility and who knows where they'll get their scheduler or memory manager from - but it's a completely open-source operating system that can run any Win32 program or any NT driver. In fact, if they implement the alternate subsystems (Win32 is a subsystem on top of NT, but there are others) you could get (for example) a Linux-compatible API on top of NT and run the best of both worlds (there actually already is a POSIX subsystem for NT, which I use to run bash, ssh, subversion, and more from within Win7).
