enjoy this week edition. A+ -- --------------- Eric Pouech (http://perso.wanadoo.fr/eric.pouech/) "The future will be better tomorrow", Vice President Dan Quayle Wine Weekly News All the News that Fits, we print. Events, progress, and happenings in the Wine community for March 12, 2001 . _________________________________________________________________ _________________________________________________________________ Headlines _________________________________________________________________ Daniel Schwarz' web site ([1] http://www.winecentric.com/) has been completely revamped and now has expanded coverage: in addition to the existing coverage of Lotus Notes, info for Microsoft Excel '97 have been added (How to install, how to use, tips and tricks, etc). _________________________________________________________________ Keeping track of Wine _________________________________________________________________ * Andreas Mohr contributed a winecheck script that lets users check that Wine is configured somewhat correctly. * Alexandre Julliard made the wineserver protocol reentrant. * Ian Pilcher moved the PostScript AFM loader's previously hardcoded font paths into .wine/config instead. * Other Workers/Bugfixers: Marcus Meissner (KDE2 support), Gerard Patel (misc dialogs and menus), Mike McCormack (overlapped I/O), Rein Klazes (message conversion), James Juran (win98/2000 stubs), Nerijus Baliunas (Latvian), Hann-huei Chiou (Chinese) + CodeWeavers: François Gouget (winemaker), Dmitry Timoshkov (edit/combobox control), Huw D M Davies _________________________________________________________________ Discussions on wine-devel _________________________________________________________________ This week, 30 posts consumed 128 K. There were 16 different contributors, 4 (25%) posted more than once, and 6 (37%) posted last week too. The top posters of the week were: * 9 posts in 31 K by "Alexandre Julliard" <julliard(a)winehq.com> * 5 posts in 28 K by David Howells <dhowells(a)cambridge.redhat.com> * 2 posts in 7 K by Gavriel State <gav(a)transgaming.com> * 2 posts in 24 K by Michael McCormack <mccormac(a)aals27.alcatel.com.au> Enhanced asynchronous I/O Evolution Michael McCormack provided a first version of a patch to enhance the I/O operations in Wine: This patch moves responsibility for asynchronous I/O to the client process. I think this implementation is more efficient, as it makes fewer server calls and duplicates fewer file descriptors, while maintaining correctness. However, Mike requested some feedback on his patch. Alexandre Julliard objected several points: * first of all, the patch conflicted with underway work from Alexandre: "your approach is not going to work with the latest changes I made to the server. The good news is that the changes I'm making are in part to allow making server calls in signal handlers, so when this works you should be able to use SIGIO to do async IO." * secondly, Alexandre really doubted the patch improved the performance. Mike tried to defend a bit his changes (especially, in the area of performance, where Mike thought he drastically reduced the number of context switches and the number of server calls), but Alexandre remained dubious: "Reducing the number of server calls but making them more expensive is not necessarily a gain. Show me the numbers..." Later on, Mike provided a second patch (a derivation of the first one, making use of Alexandre's latest improvements on the server communication protocol). Here are the final results of a simple test program Mike wrote (against Wine 2001/03/05): Wine's patch average write time for "AT" command average read time for response vanilla 675 µsec 634 µsec Mike's patch 362 µsec 322 µsec Sounds like a big gain!!! However, this doesn't fix one of Alexandre favorite topics: getting rid of the service thread (it's only use as of today is the handling of asynchronous requests). Using (SIGIO) signals should help getting rid of it. So, this discussion is likely not finished yet. We'll keep you posted with its follow-up. Wine's speed up (cont'd) Evolution Following [2]last weeks' discussions , David Howells, Alexandre Julliard and Gavriel State resumed their exchanges. David re-iterated his "main gripe against the slow speed of access to files... Every Read/WriteFile goes to the wineserver to convert the handle into a file descriptor and to check for locking. The FD is then passed back over a UNIX domain socket, used once and then closed." Alexandre Julliard explained this had just been enhanced: the file descriptor is only transferred once. All subsequent accesses only check if the file descriptor on client's side is still valid, hence reducing the complexity and the length of the server call (but, not the number of calls). The latency of the Wine server call is rather high as David explained: Context switching is the main element of it. Going to the wineserver and back again just for a ReadFile() call or a Wait*() function incurs a fairly serious penalty (particularly on an X86, I think). Plus there's no requirement for the kernel to pass the remains of your timeslice to the wineserver and back again. Since the context switch also implies that "you have to flush all the CPU caches, muck around with the MMU and execute scheduling algorithms", this can explain some of the latency. However, Alexandre thinks "that it should be possible to improve that by a small kernel hack. It will never be as fast as doing everything in the kernel of course, but it may just be fast enough to avoid the need to reimplement the whole server." and that "we are doing more than two switches (though I haven't proved it), which is why I think there is a margin for improvement. You'll obviously always have the context switch cost unless everything is in the kernel." By a small kernel hack, Alexandre means " having a specialized fifo, a network protocol, an ioctl, etc. Basically any mechanism that ensures that we do the strict minimum number of context switches and schedule() calls for a server call. And probably also a way to transfer chunks of memory from the client address space so that we don't need the shared memory area. ". David already suggested a new protocol (AF_WINE) which could nicely fit into this category (and also let the ability to use the internal API on non Linux platforms, although the kernel module had to be rewritten). David also asked Alexandre how does he "plan on doing the locking stuff for Read/WriteFile? Cache it locally? It is unfortunate, but you can't really make use of UNIX file locking, since this is mostly advisory and as such doesn't actively stop read/write calls.". Alexandre quickly replied "Yes, we'll need to store the locks in the server and check them before each read/write (and probably also release them afterwards if necessary). There may be some optimizations possible, but we should probably do it the easy way first.". This would, of course, require some more server calls. Later on, Gavriel explained that Alexandre would unlikely accept a huge patch at once, and that he'd rather have an incremental approach. Alexandre answered, but also spoke out some directions for adding such a kernel module David is working on into Wine: The kernel module itself may be hard to do incrementally, but you should really consider reusing the existing server API so that your module can be plugged in easily. For instance your module entry points should be the same as the server requests, and use the same request structures. As a reminder, David used the int 0x2E trap (as any NT system does) to hook the kernel module up to the Wine code, putting more into the Linux kernel than Wine currently does with its wineserver. However, this introduces another API into Wine, and makes it quite difficult to maintain the two APIs (the INT 0x2E and the wineserver's). Alexandre explained what he had in mind a bit more clearly: "I'm not suggesting keeping the current socket stuff, just reusing the structures. So basically instead of passing the address of the stack arguments (which is really ugly IMO) to your ioctl, you pass one of the server request structures. This allows your changes to be localized to wine_server_call and doesn't require changing any of the routines that make server calls. Obviously you'd need some more changes for a few calls like ReadFile/WriteFile, but most operations could switch to your mechanism without needing any change. You simply cannot require people to recompile all of Wine to use your module." David also pointed out some strange issues with Wine loader. After some discussion, it turned out that alignments required by mmap did change between Linux 2.2 and 2.4. Wine did made the assumption that "Page alignment is needed for the address in memory, not for the offset inside the file on disk; since section virtual addresses in PE files are always page-aligned the memory address is never a problem. The only problem comes from the alignment of the data inside the PE file, and this is where we only need block-size alignment to make mmap possible." David also proposed some enhancements for the Linux 2.4 kernel. As a (temporary) conclusion, the area of optimizing the Wine architecture is still under heavy discussion. Many tracks are available, and the potential results/benefits are still not 100% clear. On the bright side, there's still lots of space for improvement.

Currently, Alice runs at about 50% the framerate it gets in Windows with the same graphics driver (NVidia). When we started investigating, it turned out that the reason for this is that it's spending half of it's time in the WineServer. At first we assumed that this was due to the fact that the GL thunks need to grab the X11 lock. We realized that this wasn't necessary for most GL calls if we're using a direct rendering GL implementation, and turned off the locks. There was no effect - because there really wasn't much contention for the x11 lock. After going through a number of similar Wine internal possibilities and getting nowhere, we finally realized that the problem was the app itself. It's grabbing and releasing a mutex of it's own bazillions of times each frame. Since there's nothing much we can do about that we started thinking about the proposed linux kernel module approach. After re-reading the thread (EdNote: you call also look at [2]WWN coverage part #1 and [3]WWN coverage part #2) and looking over the prototype, I have to concur with Alexandre's judgement - the prototype that exists is trying to do too much work. Gavriel and Ove Kaaven proposed to use a shared memory section between every process and the Wine server to help speeding up the lock/unlock operations. Alexandre Julliard didn't like the approach at all: I don't see how you are going to make this work reliably. A basic design principle of the server is that no matter what a client process does, it cannot break either the server or other clients; given the number of bugs Windows apps contain, I feel this is very important. As soon as you introduce a shared memory area, you need the collaboration of all clients to ensure the stability of the whole system, since any client can corrupt system data structures. This is very bad. Also since the server is single-threaded its data structures don't need to be protected; but as soon as you manipulate them from multiple threads you need locking mechanisms, which will probably cost a lot in performance too. Gavriel tried to minimize the impact on system stability of his proposal, but he couldn't convince Alexandre of it. Robert O'Callahan put on the table some other algorithms to tackle the issue. Unfortunately, they either required some "ugly" (read not accepted by Alexandre Julliard features) like letting the wine server call back some function on the client side, or using the already rejected shared memory approach. As a conclusion (since none went out of the discussion), it may be possible that Gav (with TransGaming) writes an almost right but quick implementation of the mutexes, but which wouldn't be commited into the main Wine tree because it wouldn't be completely right. Wine press coverage Report Eric Pouech posted a link to a [4]C|Net article, making a comparison of three Linux products, letting Windows applications run on Linux. Those products are Wine (of course), VMware and Win4Lin. The article is pretty much product (and end user) oriented, hence the final bad ranking for Wine (so far, the Wine had put more effort into adding feature, rather than putting a 1.0 version). However, the potential for Wine is here. It just needs some more (oouch) work to terminate the developments. Here are the overall comparison from the CNET Linux Center's review by Bill O'Brien:" Product Overall rank (1..10) The good The bad The bottom line VMware Workstation 2.03 9 Provides a self-contained Windows environment that makes its Linux host platform nearly immune to collateral damage. It's expensive. VMware is an essential IS tool for multiplatform application management. NeTraverse Win4Lin 2.0 7 Simple installation; good documentation; works as promised. No DirectX or Windows networking support. Win4Lin is a bargain Windows emulation platform if you need just the basics. Wine 5 Runs Windows apps without Windows; strong user community Difficult to use; spotty application support; still under heavy development. With its innovative approach to Windows compatibility, Wine is destined to play a major role in the world of Linux. But for now, it's not quite ready for prime time. " C Code style Evolution After an unwanted semi-colon had been found where it shouldn't: loops of the form: for (i = nFirst; i <= nLast; i++); { /* do something */ } , Andreas Mohr proposed several things. First of all, he wanted to add a space between the closing parenthesis and the semi-colon to indicate clearly the intent of putting an empty C expression. François Gouget replied he preferred the writing of such cases as <init_expression>; while (<test_condition>) { <update_expression>; } Alexandre Julliard more than agreed: he converted such cases into the while form of the loop. Andreas also looked for other places plagued with the same default and found another one (which he of course fixed). Unsurprinsignly, this almost started a flame war on coding style (how many spaces for a tab, which indentation style...). But it didn't happen. Wine developers seemed to like sticking to the rule of letting the developer do what best fits him (her), even if this doesn't provide a consistent coding style across the source files.

I achieved my first goal of getting it to run in server mode. One of the things I needed to get the game to do, was to recognize that there where some interfaces it could talk TCP/IP out of. It took me some time to realize that under windows it was doing this by looking for the key [System\\CurrentControlSet\\Services\\Class\\NetTrans] and was then enumerating the keys under it to establish an IP address ie the following: [System\\CurrentControlSet\\Services\\Class\\NetTrans\\0000] "IPAddress"="10.0.10.100" The thought occurred to me that maybe the tool the builds the registry during wine install could actually create these keys - since it is essentially a key part of the system (and other similar keys are also built in the same way). " Ove Kaaven agreed on the utility of the key itself, but noted that "the IP address can change between Wine invocations (PPP, DHCP, and things like that), so it would have to be a dynamic key, generated at Wine startup or something like that." There is already some keys which are dynamically generated (like the processor information - Pentium, stepping... - or copying the contents of the init files into Wine specific registry keys to ease the reading of those configuration afterwards), so the approach could be extended. However, Ove wondered how the network interfaces could be gotten from the OS in a portable way ? There hasn't been any answer so far. Setting up a Wine's test harness Evolution John Sturtz (re)-opened the long awaited issue of bringing up a test harness for Wine (and its implementation of the Windows API). I work for CodeWeavers here in St Paul. Awhile back, I was set to the task of working on winetest, a Wine application which provided a flex/bison-based parser for a little scripting language from which Wine API functions could be called. The idea was that one could write test scripts which would call Wine API functions and examine the results, and the scripts could be used for regression testing of Wine. The scripting language began life with a rather Perl-ish syntax, and as functionality got added, it got more so. Eventually (about the time I had implemented a pack function, and wanted an unpack), I decided to see if I could write a Perl extension that provided a gateway for calling Wine API functions. That way, scripts for regression testing could be written directly in Perl instead. John then provided a first implementation of this (you can find it at [1]ftp://wine.codeweavers.com/pub/other/perlwine.tar.gz). Basically, what you can do with this is invoke some tests like: $atom = kernel32->GlobalAddAtomA("bark"); Joshua Thielen pointed out that some existing Perl modules for Win32 (from the [2]ActiveState site) allowed to provide the same interface as John's work (which was Linux based only). Alan Gonzalez also noted that this "will work out of the box on cygwin for windows using the perl 5.6.1 that is bundled with it." Jeremy White then started to figure out what the test harness should contain: "I think it would be great if we could start to define (and build) a test harness. I think that there are a lot of people who would help write test scripts, who might otherwise be unable to help with Wine development. The more the merrier, I always say... " Jeremy started to split out the test cases into two categories: * non-interactive: no user interaction is needed * interactive: user interaction is needed As already covered (see [3]this article ), a free test tool for X11 regression test has not been found yet, making the second category a bit difficult to run. Eric Pouech proposed to have a two pass approach to run the test. First the test case is run and outputs some results which are stored into a file. Then, the contents of this file is compared against a reference file. This would allow, beyond the simple regression idea - running twice the same program should provide the same results -, to compare the output between running the program under Windows and running it under Wine. Eric also liked to idea of writing test cases in C which would allow to test three cases: * test case compiled and run under Windows, * test case compiled under Windows, and run with wine * test case compiled under Unix as a Winelib application Alexandre Julliard really backed up the idea of the Perl test scripts: "The idea of using an interpreter like Perl is precisely that you don't need to compile anything to run tests. I think this is important because not everybody has a Windows compiler. It also allows using the exact same test script under Windows and Wine, so that you don't have to worry whether your Windows binary exactly matches your Winelib binary. " Eric and Alexandre further argued whether it was more common not to find a compiler or not to find a Perl interpreter on a PC/Windows box. François Gouget also liked the C/C++ tests because " The downside of interpreter-based tests are: * they won't test the Winelib headers or Winelib specific issues * I imagine that some of our potential test writers would be windows programmers (after all these tests would be nothing more than simple Windows applications). They would probably be more comfortable writing tests in C/C++. " The thread ended with Eric and Alexandre still arguing on some other points. All the details of the test harness are not settled down yet, but the effort of providing such an environment has started. We'll keep you posted with the advances. Wine .so files' names Issue Andreas Mohr asked whether all the Wine libraries shouldn't be renamed to libwineXXX to avoid any conflict with existing libraries. Wine already had a clash with libole.so and gnumeric. After some discussion on how the current distributions were doing their packages (Debian, RedHat...), Ove Kaaven explained what should be the final scheme. The Wine DLL files (to be semantically correct, read the .so files containing Wine's DLLs ; see [4]for the details) should be stored in /usr/lib/wine (as FSH suggests). All the other .so files (like libwine_unicode, libwine_tsx11...) should be stored into /usr/lib (or any directory pointed by /etc/ld.conf). /usr/lib/wine shouldn't be referenced by the /etc/ld.conf configuration file. Any program (winelib or wine itself) which wants to import a file will do it through the import directive of its .spec file (and will not require the support of the linker (like using -lfoo) for that). In other words, all is already in place for a proper storage, avoiding any naming conflicts.
