Lindows screenshots
by Hetz Ben Hamo 11 Jan '02

11 Jan '02

Hi, I just got this - Lindows released 2 screenshots of their Lindows: www.lindows.com/screenshots Now, IF they did use wine (and thats a big if - from the screenshots they're running either Office 2K or office XP, Internet Explorer, the fonts looks like MS TTF fonts, and I think those screenshots are modified a bit - look at the 2nd screenshots, behind the start menu - look at the "file/edit/view" menu - it should be alligned to the left) and they'll contribute some parts of their wine to the standard wine - then wine will be in much better shape then what is it today.

How about sponsoring from IBM?
by Roland 10 Jan '02

10 Jan '02

Hello, it seems that IBM is becoming a major Linux advocate. What would be the possibilities of having it sponsor the WINE project? I mean 1 Million dollars is not much for IBM, but it certainly would mean a lot to the development of WINE. IBM would also profit of this. Since Linux runs on their supercomputers, it would be nice if you could run all Windows programs there(you need another Pentium emulator then, but that would not be a big problem, would it?). Just thinking about this... Roland

Thanks p.s. you DO need the .DLL (at least I do) (break MyDll.DLL.EntryPoint) Bill

Babystep: Testing framework
by Jeremy White 10 Jan '02

10 Jan '02

The attached revision to Alexandres patch modifies the Wine makefiles such that a Linux developer can: make test (to confirm all regression tests) make clean-test (to clear the tests and try again) It also creates three sample tests in programs/winetest/samples which hopefully demonstrate to a test author how to write a test. (The *.test files are human readable). It has provisions for Perl and Winelib/C tests, as well as allowing for the arbitrary execution of any other command (which should allow any other test tools to be plugged in). It has many flaws, but is intended as a possible jumpstart to get this process rolling. Flaws: 1. It has no provision for use on Windows. IMO the right way to fix this is to go through the effort of making Wine's ./configure script be intelligent enough to build 'Winelib' programs, so that in Windows a 'make test' should just work. 2. I really don't like that a C/Winelib test requires its own directory (see samples/sample3). However, AFAICT, that was the only way to create a simple and clean build environment for the Winelib app. 3. No doco. Thoughts? Comments?

Debugger set breakpoint with full filename
by Bill Medland 10 Jan '02

10 Jan '02

I've spent time looking for the answer and trying the (to me) obvious options and now I give in. How, in the debugger, do I specify "Set a break point at DllMain of E:\BIN.50A\..MYDLL.DLL" without the debugger complaining about syntax etc.? If someone answers then I am prepared to add the info to debugger.sgml Bill

Re: Immediate IO in ReadFile / WriteFile
by Mike McCormack 10 Jan '02

Hey Martin, As Lawson said, some programs use WaitForComm event to wait for data, then GetCommError to check how many bytes arrived, then ReadFile to read it. They then expect ReadFile to return TRUE. One such program is VBTerm, the visual basic terminal program, or at least the VBX in it. Testing applications that use serial ports is difficult, and debugging often must be done remotely. (eg. send me a trace like this, apply this patch and send me another trace, etc.) After making a change, i usually get a terminal program (such as KoalaTerm) and send a couple of "AT" commands to it... :-) Mike Original message from: lawson_whitney(a)juno.com > >On Wed, 9 Jan 2002, Martin Wilck wrote: >.... >> How do you check if data is ready in Windows?

int $3 and pstores service
by Travis Michielsen 10 Jan '02

10 Jan '02

Hello, I have been tracing into pstores.exe the protected storage sevice provider in windows (win98). This service may be necessary to get the cryptographic API to function using native dlls (no wine providers currently exist). I noticed that the service was being started using the following calls: 1) The program calls CryptAcquireContext. 2) CryptAcquireContext calls CPAcquireContext of the apropriate service provider 3) Any MS provider I tested would call PStoreCreateInstance in pstorec.dll 4) pstore.exe would be started by a call to CreateProcessA Immediately after the call to CreateProcessA, a call to interrupt 3 seems to be made but doesn't appear to return. Anyone know what this interupt does or sopposed to do? Is there any support for it in wine? A few other notes: -pstores appears to execute fine when started directly under wine. -when started from above it seems to crash (randomly?) depending on the provider? usually tries to execute the instruction at 0x00000000. -some other calls in the API appear to rely on this service I *think* through psbase.dll (but maybe pstores.exe somehow). I haven't verified this yet though. Anyone have some suggestions? - Travis _________________________________________________________ Do You Yahoo!?

Is W really UTF-16?
by Bill Medland 09 Jan '02

09 Jan '02

Sorry to resurrect an old subject, and please excuse my ignorance; I am only just getting started on this "character encoding" stuff. While I was working on the DrawText functions over the past many months I started wondering about when it would fail. (I'm pedantic and such things fascinate me!). The main concern I have is how to walk a W string correctly. For example while "ellipsifying" text we will need to "move the pointer to the previous character" which is currently done by decrementing the pointer by 1. But from what I currently understand that won't work if there are surrogate pairs. I see that MSDN these days keeps talking about surrogate pairs and the fact that strings of WCHARS might include them and I started to get the impression that the inputs to the W functions were truly UTF-16. I have just been looking at the discussions from April 2000 on this subject and I get the impression that we believe it too. My understanding of UTF-16 is that a surrogate pair is quite obvious and doesn't require any context information; if you come across a 16 bit value in 0xDC00 to 0xDFFF then it must be the low surrogate and there must be a high surrogate just before it. So I presumed that CharNextW must be the function that correctly walks a W string and I tried to find out what its behaviour was for the error cases (e.g. high surrogate with no low surrogate). On finding that CharNextW didn't do anything clever, it just incremented by 1, I tested and found that CharNextW always incremented by 1. So now I am confused. 1. Does anyone know under what circumstances CharNextW isn't +1 (apart from when pointing at the terminating 0) 2. Is e.g. XP really using UTF-16 or is it actually still UCS2? 3 Have we thought about how we should handle walking along a W string (in a fashion that doesn't reduced the speed to a crawl). I guess that in the short term I am expecting some sort of macro or inline. Bill Medland

Re: Immediate IO in ReadFile / WriteFile
by Mike McCormack 09 Jan '02

09 Jan '02

Hey Martin, Another day, another problem. :-) You can't unconditionally use overlapped operations... the code used to do that exactly, and it caused all sorts of breakages. eg. some (braindead) programs check that there is data is ready to read, then do an overlapped read, but expect it *not* to go overlapped. I don't think WaitForMultipleObjectsEx(0,NULL,FALSE,0,TRUE) then read, is the right way... I think the best solution is to let the server decide. Something like this: BOOL ReadFile_overlapped () { ovp = new async_private; while(1) { ovp->func = FILE_AsyncReadService; wine_server_call(register_async); switch(GetLastError()) { case STATUS_SUCCESS: ovp->func(ovp); break; case STATUS_PENDING: return FALSE; case STATUS_TIMEOUT: goto finish_it; default: delete ovp; return FALSE; } if(count >= bytes_to_read) break; } finish_it: delete ovp; *bytes_read = count; } This is the kind of structure i was trying to describe to you in a previous private mail... i was trying to address a different problem but it should address the one you mention too. In fact, WaitCommEvent also needs to work in this way. (Somebody on wine-users has a program that needs that behaviour now.) There's a minefield of special cases... but the essence is that the wine server instructs the client to do one of the following things: * perform the action (read/write/etc) * return from the call with success * return from the call with ERROR_PENDING * wait for an event flag (ie. not return yet) Does that make sense to you?

A new async patch - feedback, please :-)
by Martin Wilck 09 Jan '02

09 Jan '02

Hi Mike, all, Unfortunately this patch has become big, because i came across so many problems today and I just needed to go forward. I am sorry for this, but it has become very late tonight, and I want people to see this stuff to stop me before it's too late (if I'm on the wrong track). It compiles without warnings, but I have not tested it - may crash wine right away, I don't know. However it should illustrate my ideas well: * Full separation of async handling and file io-specific stuff. * Do not rely on LPOVERLAPPED for status data in generic code, it may be NULL. File IO code may rely on it, here it is required to be non-NULL. * Use GetOverlappedResult() to check for immediate completion (UNTESTED!) Please give me comments telling me which parts you don't like, so that I can adjust for further development. Mike, can you tell me about those apps that were causing trouble in the past ? Where can I obtain them? Do they need special hardware (modem, mouse) for test runs ?

I don't see any value in information about the first TODO check in a test script. I, personally, prefer using "magic call". One more plus of autodetection - I can run the same Windows test binary on Windows and on Wine without any troubles. But I'd like to use your idea in other place. I feel uncomfortable when test does not show anything. It is not clear whether it runs any checks, whether my last changes were executed. I suggest to have switch which turns off output. By default the test will print some statistics on successful run - number of tests running, number of TODO tests, time of execution - anything else? Make script can run test with output turned off.

I already created small library with api like in Test::Simple - functions ok, TODO, SKIP. The implementation can be easy changed to the behaviour you described. I also suggest for library to fail on successful TODO test. TODO tests will be conditional - they are TODO only under Wine, not on Windows. Careful usage SKIP sections can easy cover differences between Windows platforms, using TODO - between different non-Microsoft Win32 implementations. On other hand, SKIP sections were important for Test::Harness, which needed to control number of tests. For your goals conditional execution of the tests is sufficient. Which approaches can you suggest to reach goals I believe are important: 1) bundling - are we going to have separate distributions - Wine with tests, tests only, Wine only? There are a lot of cases where only one of them is required. 2) development of the unit tests under Windows. Obviously, we don't need to have Wine itself when we work with unit tests on Windows. Plus, we need to create development environment, usable by Windows developers. 3) Organization of the unit tests in such way, so they can be used by other Win32 implementation projects. Conditional TODOs I suggested above will help to manage different TODO lists for different projects. 4) besides narrow-scope regression testing you suggested we need to run all the tests from time to time, even if it takes more than 1 hour to run the whole suite. The reasons for this are: a) we need to run the tests on all Windows platforms to make sure the tests correctly document their behaviour b) Wine should be reguraly tested by the whole testing suite. Some regressions will be caught in unit tests of the modules other than changed. In other cases changed module may not have tests at all, but will brake modules, dependent on it.

Listview ctrl
by Dimitrie O. Paun 09 Jan '02

09 Jan '02

Hi folks, While I looking for something _small_ to do, I discovered that listview.c had two of those HEAP_strdupXXX calls that Alexandre hates so much. I figured that's got to be a 2 minute job, but I was wrong -- it turns out that the listview control needed to get Unicode enabled. So, after much work and no testing, here is a first try at doing that. The good news is that it seems it compiles. The bad news is that I have no idea how to test it. So any suggestions on how to test the listview control, or any help with the testing is greatly appreciated, as well as any comments on the patch itself. Alexandre, why is it that you want so badly to get rid of the HEAP_strdup functions? I mean, in certain cases they are not needed, and they rather signal that the code needs fixing, but in other places they _are_ needed and they convey a heck of a lot better what we're trying to do then the strange WideCharXXX function calls. -- Dimi

lpOverlapped = NULL
by Martin Wilck 09 Jan '02

09 Jan '02

Mike, I should have been aware of this before :-/ As mentioned in my other mail, ** Winsock allows NULL pointers for lpOverlapped. ** AFAICS, Mike, your server-side code uses the overlapped field only for identifying a certain request. This will obviously break if the overlapped field may be NULL. Question: Would it hurt to use the async_private pointer of a request rather than the overlapped pointer to pass to the server? If no, I guess that would be the way to go, because the async_private structs are allocated by us and therefore necessarily different and non-NULL. Wrt to the status and "bytes read", I already have a pretty elegant solution which keeps the overlapped struct outside the generic code (scheduler and server).

struct async_private needs generalization for Winsock
by Martin Wilck 09 Jan '02

09 Jan '02

Hi Mike, all, as I pointed out before, we must change the async_private type such that it accomodates the different needs of normal (e.g. ReadFileEx()) and Winsock (e.g. WSARecv()) async requests. The "generic" functions in scheduler/synchro.c must be able to handle these structures without knowing what type of async_private structure they have been passed. I try to summarize the differences between the two request types here: 1. Winsock async requests have a WSAOVERLAPPED struct rather than OVERLAPPED. Unlike File I/O, the routines complete if any positive number of bytes is read (there's no such thing as BytesToRead). 2. Unlike File I/O, The WSAOVERLAPPED struct is *not* accessed in any way, except for the hEvent field. The other fields do not carry useful information and are, according to the Winsock2 specs, reserved to service providers, i.e. we are not allowed to write to them. 3. Winsock functions take a scatter/gather array of type WSABUF* instead of a single buffer, and a number of WSABUFs instead of the number of bytes to read. 4. The completion routine takes an additional DWORD argument. 5. In the case of WSARecvFrom()/WSASendTo(), the socket address and length parameters passed by the user must be stored and filled in at completion. [These are the differences I've come across so far, there may be more.] I'd therefore recommend the following, similar to the treatment of "struct object" and derived types in the server code: struct async_private; typedef void (*async_handler)(struct async_private *ovp); struct async_private { unsigned int type; /* file/socket, read/write/... */ HANDLE handle; int fd; struct async_private *prev; struct async_private *next; async_handler func; } struct async_fileio { struct async_private async; char *buffer; int count; LPOVERLAPPED lpOverlapped; LPOVERLAPPED_COMPLETION_ROUTINE completion_func; } struct async_winsock { struct async_private async; LPWSABUF wsabuf; int n_wsabufs; LPWSAOVERLAPPED overlapped; LPWSAOVERLAPPED_COMPLETION_ROUTINE completion_func; struct WS_sockaddr* addr; /* User-specified pointers */ int *addrlen; int flags; /* Return values */ int NumberOfBytesRead; int status; /* cannot be stored in overlapped */ } To my knowledge, there are only these two types of Asynchronous requests. Thus, using a "struct async_ops" like "struct object_ops" in the server code would probably be too much; the type field could instead be used for distinction between the two request types and the "generic" code in scheduler/synchro.c could incorporate respective case distinctions. To my experience this runs faster than code with function pointers if we have only two cases. Actually, we might even do without the "async_handler" field and decide which function to call only according to the "type" field, but that's a cosmetic issue. Unless anybody objects, I'll soon submit a patch incorporating this approach.

Immediate IO in ReadFile / WriteFile
by Martin Wilck 09 Jan '02

09 Jan '02

Hi Mike, I just had the following thought on the immediate IO in ReadFile() / WriteFile() that you implemented: Consider the following situation: 1. There is no data available for reading on some fd (serial port, pipe, socket). 2. An application calls ReadFile() in overlapped mode. since no data is there, an overlapped request is scheduled. 3. Data becomes available before the app issues a wait request of any kind. 4. The application starts another ReadFile() request. Now data is there, and will be read immediately. No async request is scheduled. 5. Eventually, more data will become available, and the async request first scheduled will also return. However, this basically destroys the order of the requests. I am unsure how Windows would behave in such a case, and it is certainly difficult to provide a test case for this situation. It can occur, though, and my guess is this is the wrong behaviour. Thus, probably before doing the immediate read it should be checked if there are asynchronous requests already scheduled for reading, and if yes, ReadFile() should _not_ try to read immediately but go pending. Of course, this check would require a server call. The same reasoning applies for writing, of course. Things become even more confusing if you think of several threads reading from the same file. A very simple workaround would be to go pending unconditonally for overlapped requests. Although not optimal, this would be certain not to corrupt data. What do you think?

The whole point of the FD_TYPE_XYZ distinction, as it currently is, is that at some places (actually, only in WriteFile() and ReadFile()), a distinction according to fd type _must_ be made. I am not sure if Windows allows overlapped IO on the console, for example, but if yes, this patch would be a prerequisite to implement that. I just wanted to make this distinction more logical. I think it is necessary to separate fd types and flags. The distinction between regular files, pipes, sockets, ... that the patch introduces is currently not needed, but doesn't hurt IMO. If you wish, I can strip the patch down to its essential part (have separate flags for overlapped and timeout flags). I guess I could also proceed entirely without this patch, if you seriously reject it as a whole, but I fear this will bring trouble sooner or later.

Re: We *really* need a development model change !
by Andriy Palamarchuk 09 Jan '02

Spent a couple of days trying to port my test to C unit testing framework "Check". Simple tests work fine. Problems start when I try to use multithreaded Wine tests. In one case the framework stucks on reading from pipe. Other code layouts have other issues. The cause may be in incorrect pipes handling, multi-process tests handling or interaction with Wine thread implementation. I remember I also had some problems with Perl multithreaded tests... I attached my unit test example, almost identical to the one I published before for Perl framework. There is also a whole working directory. If you want to play with the it, just unpack it to wine/programs directory. Andriy Palamarchuk __________________________________________________ Do You Yahoo!? Send FREE video emails in Yahoo!

With rowlist.exe that comes with Vc++, using 'large icons' and 'full details' only the first character of the text is displayed. The little program found at www.timex.com (IIRC it installs correctly under Wine) displays another problem (maybe related) : columns other than the first can be not displayed in some cases. Gerard
