A window painting problem.
by Duane Clark 23 Nov '01

23 Nov '01

Howdy, Perhaps this is one of those things that is in work. But this patch causes one of the (sub)windows in the app Xilinx fpga_editor (commercial) to never get painted. The app has several windows within a window, including a scrolled window, which after the patch I can zoom in and out and move the scrollbars just fine. But the contents never get painted, no matter what I do, including hiding and reshowing, etc. All the other pieces and windows are painted fine. http://cvs.winehq.com/patch.py?id=1005773317852080273907632 Log message: Moved WIN_FindWinToRepaint functionality to the server.

Crashing menus, event handling broken?
by Jukka Heinonen 22 Nov '01

22 Nov '01

While playing Civilization 2, I noticed that Wine crashes if I click menu bar twice while the game is thinking. The reason for this is that raw hardware messages get processed before menu event loop starts. Raw event processing turns raw events into cooked events and because menu event loop has not started yet, game window is not capturing events and thus clicks on menu bar are turned into nonclient messages. These cooked messages are put back into message queue. When menu event loop starts, it receives the second nonclient button press event and passes it to DispatchMessage. Default window procedure creates a new menu event loop and since the nonclient message was still in the event queue (it would have been removed if DispatchMessage had returned), we get a nice stack overflow. The real problem is not in menu event loop but in the fact that Wine event handling forgets that we can't determine whether a mouse event is nonclient event or not unless we have already called window procedure for all previous mouse events. This is because one of those calls might have for example captured mouse input after which we no longer report nonclient events. Since event handling is quite complicated and this flaw looks more like a design error than coding bug, I would like to get some discussion about what should be done to fix this problem. -- Jukka Heinonen <http://www.iki.fi/jhei/>

Which is correct? listview or treeview?
by Bill Medland 21 Nov '01

21 Nov '01

With regard to my problem that I was getting infinite redraws in my listview following Alexandre's change to server/user/message.c: I eventually tracked it down to the fact our code used SetRedraw(FALSE)/SetRedraw(TRUE) on a list control. (So the bug can now be demonstrated easily on e.g. the MFC RowList sample with a two-line change). Now I see that in the case of LISTVIEW_SetRedraw DefWindowProc is called and then RedrawWindow. In the TREEVIEW_SetRedraw case it simply sets a flag within the treeview's data. Which is (more) correct? (And how does calling RedrawWindow once result in the repeated repainting of the treeview anyway?) I'm prepared to do the fix if no-one else can but I must admit that I am not really up on the details of the invalidation/paint etc Bill

New level of Shlwapi (parts 1 & 2)
by Guy L. Albertelli 21 Nov '01

21 Nov '01

Most of the shlwapi upgrades have been driven by my desire to be able to run Outlook Express under Wine. (I know that there are other mail packages, but the rest of the home uses Windows - anyway it is a great test vehicle, uses everything ever implemented). The current status is as follows: With V4 or IE and OE - with builtin shlwapi,commctrl,comctl32 . IE displays page, can even do www.cnn.com, even runs javascript. + Certain menu popups either fail to display, or bomb. + Needs work in comctl32 rebar for extra space. . OE seems to basicly work. + Can display messages, change folders, and create messages. + Cannot invoke address book, but can request address list when creating new message. V5 of OE - requires native commctrl, comctl32: . With builtin comctl32 + OE fails to startup . With native commctrl, comctl32: + OE comes up but is mostly non-functional. Bombs on shutdown due to shlwapi.208 and shlwapi.210 V5 of IE - Does not start up yet. Requires native shlwapi . With native shlwapi, builtin comctl32 + IE has black toolbars with white lines. Menu line real small. . With native shlwapi and comctl32: + IE has black bitmaps for button bar. Mostly functional, however cannot access dropdown arrow for address bar. <sarcasm> I really appreciate the MS developer that decided to implement menus in OE5 with objects and put some of his "common" code in shlwapi. </sarcasm> Guy Albertelli <<galberte(a)neo.lrun.com>>

Re: Improving DIB support for SHM
by Gavriel State 21 Nov '01

21 Nov '01

Doh! I guess we've been too lax about integrating some of our non D3D work back into WineHQ. We did this in WineX some time ago, but with a couple of differences: 1) We don't restrict using XShmGetImage to the whole-screen case and 2) We save and restore the XImage mask fields around the call to XShmGetImage, which seems to like to write over those fields to no useful purpose. IE: /* We must save and restore the bmpImage's masks in order * to preserve them across the call to XShmGetImage, which * decides to eliminate them since it doesn't happen to know * what the format of the image is supposed to be, even though * we do. */ saveRed = bmpImage->red_mask; saveBlue= bmpImage->blue_mask; saveGreen = bmpImage->green_mask; XShmGetImage( gdi_display, descr->drawable, bmpImage, descr->xSrc, descr->ySrc, AllPlanes); bmpImage->red_mask = saveRed; bmpImage->blue_mask = saveBlue; bmpImage->green_mask = saveGreen; We'll probably get around to doing some merging back into WineHQ after our next release. -Gav Jukka Heinonen wrote: > > The following patch halves the time it takes to move units > from one square to another in Civilization 2.

cleaning up pthreads implementation - ABI problem
by Peter Hunnisett 21 Nov '01

21 Nov '01

Howdy, I was just looking at cleaning up the pthreads implementation but I don't think that it's possible to have our pthreads implementation without providing binary compatibility with the pthread implementation we're hijacking. The reason is that the mutex and rwlock objects are supposed to be opaque to the programmer but in fact they are not opaque to the compiler. According to the standard, one doesn't have to call pthread_{mutex,rwlock}_init before using a {mutex,rwlock} as would be required with a totally opaque type. The standard allows for static initialization of the mutex and rwlock using PTHREAD_{MUTEX,RWLOCK}_INITIALIZER if you don't want any special attributes. libc does just this with its rwlock for gettext's global data. If you look at the ream of FIXME:pthread_rwlock_{rd,un}lock that sometimes come out starting wine you'll see that there's no call to pthread_rwlock_init. Of course, this stuff is safe because there's generally no writers wanting the pthread_rwlock_wrlock. So our current pthreads mutex implementation works in Linux by the skin of its teeth, becuase the first field in the mutex is reserved and initialized to 0 (in both the static and pthread_mutex_init cases), provided the version of LinuxThreads is new enough and a pointer is the same size as an int. Now I assume that this would mean it fails curiously for things that don't use LinuxThreads. This would also seem to mean, since we need binary compatibility, that things could even fail if someone upgrades their libc :( BTW, our check is presently basically only on __GLIBC__. Flavour me ignorant, and lazy, but I would assume that this not a Linux only symbol. So in fact the wine pthreads implementation might be already used incorrectly. Reader/Writer locks can be made to work the same way, as the mutex, since there are several fields which are initialized to NULL and we can then HeapAlloc our own structure off that field. We can then come up with weird and wonderful exceptions for the wonky cases that are sure to exist in some implementation of pthreads. Can anyone see a nice way out of this that I'm remaining ignorant to? I can't even think of a runtime way of detecting if our implementation is going to work. All in all I'm not too enthusiatic about the potential maintenance nightmare that this may provide but it would seem the only way is to have different mutex and rwlock structures depending on the pthreads implementation we're hijacking. Some code if people are more interested in details: >From glibc 2.2.4 /* Mutexes (not abstract because of PTHREAD_MUTEX_INITIALIZER). */ /* (The layout is unnatural to maintain binary compatibility with earlier releases of LinuxThreads.) */ typedef struct { int __m_reserved; /* Reserved for future use */ int __m_count; /* Depth of recursive locking */ _pthread_descr __m_owner; /* Owner thread (if recursive or errcheck) */ int __m_kind; /* Mutex kind: fast, recursive or errcheck */ struct _pthread_fastlock __m_lock; /* Underlying fast lock */ } pthread_mutex_t; #define PTHREAD_MUTEX_INITIALIZER \ {0, 0, 0, PTHREAD_MUTEX_TIMED_NP, __LOCK_INITIALIZER} What WINE uses (scheduler/pthread.c): /* assume that pthread_mutex_t has room for at least one pointer, * and hope that the users of pthread_mutex_t considers it opaque * (never checks what's in it) */ typedef struct { CRITICAL_SECTION *critsect; } *wine_mutex; rwlocks on the other hand are not so lucky as there's no unused bits: >From glibc-2.2.4 /* Read-write locks. */ typedef struct _pthread_rwlock_t { struct _pthread_fastlock __rw_lock; /* Lock to guarantee mutual exclusion */ int __rw_readers; /* Number of readers */ _pthread_descr __rw_writer; /* Identity of writer, or NULL if none */ _pthread_descr __rw_read_waiting; /* Threads waiting for reading */ _pthread_descr __rw_write_waiting; /* Threads waiting for writing */ int __rw_kind; /* Reader/Writer preference selection */ int __rw_pshared; /* Shared between processes or not */ } pthread_rwlock_t; # define PTHREAD_RWLOCK_INITIALIZER \ { __LOCK_INITIALIZER, 0, NULL, NULL, NULL, \ PTHREAD_RWLOCK_DEFAULT_NP, PTHREAD_PROCESS_PRIVATE } Ciao, Peter hunnise(a)yahoo.com __________________________________________________ Do You Yahoo!?

Please, it needs unistd.h so it can comfortably log to syslog. running winemaker on it again didn't help. checking for wrc... /usr/local/bin/wrc updating cache ./config.cache creating ./config.status creating Make.rules creating Makefile creating launcher Configure finished.

Civilization2 segment register troubles
by Jukka Heinonen 20 Nov '01

20 Nov '01

Hi. I noticed that Civilization 2 has several problems under Wine. First, the game wants to access memory using segment register value zero, which causes protection exception since that is not allowed in protected mode. Second problem is that the game uses segment register value 0xf8, which Wine does not like. If I drop null-pointer protection [call to DOSMEM_Init(TRUE)], emulate cmp and mov commands so that they work even if using segment register value zero [added stuff to memory/instr.c] and make Wine accept segment register value 0xf8 [by hacking INSTR_ReplaceSelector], Civilization 2 starts to work without any problems. There are several possible reasons why the above changes make the game work: Wine corrupts segment registers somewhere, Civilization 2 wants to use privileged commands and Windows emulates them or the game runs in VM86 mode under Windows. So, I would like to get some ideas what should be done with Wine in order to get the game working. Oh, the above modifications fix protection faults that happen when the game tries to access the following addresses: 0x22, 0xc8, 0xf6, 0xf07c and 0xf0aa. P.S. Civilization 2 seems to work almost perfectly but it is painfully slow. I am pretty certain that I know the reason for this, but I would like to get the game working under official Wine before trying to make it run faster. -- Jukka Heinonen <http://www.iki.fi/jhei/>

Yes of course it can, but the fact that this isn't explicitly forbidden by some standard doesn't mean it's good practice or that it doesn't pollute the namespace. sys/user.h is also legally allowed to do "#define if else"; that doesn't make it a good idea. > If an application includes > <sys/user.h>, then the application should be prepared to > deal with conflicts. Great, then you need to fix all applications every time someone feels like exporting a new symbol from user.h. Of course user.h is a pretty obscure header so it's no big deal, but it would be easier to avoid exporting stuff under such common names as "struct thread". -- Alexandre Julliard julliard(a)winehq.com

interesting comment about WINE from MS
by Igor 20 Nov '01

20 Nov '01

As far as WINE and Mono are concerned, I'm just not sure whether these organizations will end up being able to produce satisfactory products. The real problem is this: it is not good enough for WINE to run some Windows apps. If the general public is going to consume it, it must run all Windows apps. Windows 2000/XP has a significant level of POSIX compliancy, but many developers just don?t write their apps with these standards in mind. You'll find pieces of code everywhere in third party apps which run statements like if (WINVER==4.0 && GrokTheBIOSForSomeACPIGoo()), which have not been tested to see whether they will run on non-Windows/x86 platforms. In fact, Microsoft has had to put in significant time and effort to insure that older Win32 applications originally written to run in Win95 will run in NT." original article is here http://www.osnews.com/story.php?news_id=314

Of course Wine have probably slightly different requirements but I should guess that we could save 90% of the work compared to writing it from scratch.

I'm here. :-) Well, I wouldn't really go quite that far. The API definitions in themselves can't be copyrighted, true. But a specific way of expressing them is, so compiling any Microsoft file will generate create a derived work copyrighted by Microsoft as the main rule. However it is not quite that easy, since only the specific expression is protected, the compilation result is only a derived work if it still contains any protected expression. In light of this you could argue that since, I presume, MIDL removes whitespace and commments which is IIRC the only really expression, since the rest the API defintions are just facts, that the MIDL compiled files just contains facts not any part of the protected expression. However that is a little thin line to walk, since there is quite of lack of real cases in the area, so I would recommend that we do as Alexandre suggest. Beside having the real .idl files in the Wine tree might be useful for other things as well.

I'd prefer not. If we want to use .idl files we'll have to come up with our own compiler, and then we can put the .idl source in the tree and compile it at build time. > And how about source IDL files?

No, anything generated from a Windows file is copyrighted by Microsoft, so we cannot distribute it. We need to rewrite these files from scratch, just like we do for the normal headers. > Problem 2: RPCSS > rpcss.exe is the place that keeps track of which process owns which RPC > endpoints, exported COM objects, and object activation tables. > The IRunningObjectTable interface, for example, is managed by rpcss.exe, > and keeps track of certain kinds of COM objects on the computer, so that > other processes can connect to running COM objects.

I'd prefer having a separate process, at least in the first stage. -- Alexandre Julliard julliard(a)winehq.com

audio.c regression on Nov. 10th
by Ori Pessach 19 Nov '01

19 Nov '01

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, Despite my previous report on this, something did break in audio.c between November 9th and November 10th. I checked out a version from 11/09/2001, and it works. I updated just audio.c with -D 11/10/2001, and Humongous Entertainment games don't recognize the sound card anymore. There have been substantial changes to audio.c during those 24 hours - enough to confuse diff, as a matter of fact. I'll look into it, but I wanted to report this first. The reason I thought earlier that the problem went away was that I had a sticky date on audio.c that I wasn't aware of.

Re: Patches for FreeBSD 5.x compilation

Well, struct user is the only reason for including sys/user.h, so I guess it can be considered acceptable; but anything else defined in there (like struct user_regs_struct on Linux) is namespace pollution too IMO. And if there comes a day when the server is managing users, the corresponding struct will definitely be named struct user, not struct wine_unique_prefix_0918274_user or whatever (and note that we don't really need user.h even on Linux, we could just as well hardcode the offset). -- Alexandre Julliard julliard(a)winehq.com

It's still made available to applications, and there is really no reason for exporting internal kernel names this way. At least it could be renamed or put inside #ifdef _KERNEL. The alternative is of course to avoid sys/user.h, or play with #defines on the Wine side; but prefixing our structures with wine_ is not a solution. -- Alexandre Julliard julliard(a)winehq.com
