Newbie developer looking for pointers (re printing)
by Carl Sopchak 05 Apr '02

05 Apr '02

I've decided to try to fix a problem myself that I'm having printing from QuickBooks (partial page checks need to be landscape). I've downloaded the source, updated it via CVS, and now I'm trying to figure out where the problem is. I know where the problem is at the moment: ME! :-) That is, I could use some pointers on where to look... I have no knowledge of the Win API, and I can't say that I'm a strong C programmer (although I've played with it for a while a few years ago). However, being a consultant for over 15 years, I've jumped into more difficult situations and got results in a reasonable period of time. With a few helpful pointers, I don't think this should be any different. :-) I've looked around MSDN for a while, searching for printing API info with no luck (perhaps it's a lack of patients, perhaps its a poor search enging on top of a huge mass of information). I've looked at the Wine source, have successfully watched my program trace through wineps.c (et al), and even made a slight mod to it to make sure that I would know that I was running modified code (which worked). I've also looked around winehq and codeweavers, in the wine developer's sections... Here's where my head's at: It seems to me that I'm "too low" looking at wineps.c, but I can't figure out where else to look. Using the cross reference on winehq, and looking at the "where used" for wineps.c, the trail "goes cold" after a level or two (still "too low"). I know the app is making the proper calls to the Win Printing API to set landscape mode when needed since the program works fine on an NT box. I just don't know WHAT gets called to do this! If I started there, I could trace down to whatever levels I need to to figure out what is currently going on, so I can figure out what needs to be changed... So here are my questions: - What APIs are called by programs to talk to the printing subsystem? Is there a MS URL that gives an overview of this API? - What --debugmsg options can I use to trace programs through these API calls? (+psdrv works for the routines in wineps/*.c; +gdi [am I on the right track?] seems to give a whole bunch of traces, none of which [well, maybe a few] seem relavent.) - What calls the PSDRV_ functions? What's the --debugmsg option for it? - Is anyone willing to Mentor me?? (VERY big grin; flash the long eyelashes; etc.) I'd love to get this to work, and I'd be more than happy to supply the patch once it is working. I'm also be willing to continue working on the printing in wine, and perhaps fix other bugs that I run across. But in order for this to become reality, I sure could use some help up the learning curve!! Humble thanks, Carl

Crossover/WINE Test In Large Rollout
by Dave Richards 05 Apr '02

05 Apr '02

All- I am not on this list, so if you would like to respond to me you will have to reply to me directly. This is a real world situation where WINE could be used for a massive sever rollout (hundreds of users) and is having some problems in our environment. The City of Largo, Florida is a large Linux and thin client shop that has deployed a PC-less network for running out software. We are currently doing some R&D into options for running Lotus Notes in our environment. Our first choice obviously would be a native client running on Linux---it doesn't exist. We haven't looked at WINE in about 2 years and today the kind folks at CodeWeavers allowed us to test their new release with the Lotus Client. Here are the problems--> 1) Endian Bug. WINE is not able to detect that the runtime Endian order might be different than the server. Our Xterminals are RISC based and obviously WINE is running on Intel. All of the colors display incorrectly because of this. 2) Performance. On remote displays WINE is *much* slower than it is on the console. The Lotus Notes client took over 5 minutes to run remotely whereas on the console it comes up in about 20 seconds. I am assuming that it is making use of some of the XFree extensions for performance and that perhaps they have to timeout and drop through code in order to run on our Xservers. Once it is running, performance is much better, but the initial startup make it undeployable. We are thankful for everyone that has gotten WINE this far and that it works as well as it does considering the complexity of this task. If these areas are ever addressed, we would be happy to explore the product again! Dave Richards City of Largo, FL Systems Administrator

Re: [PATCH] async IO APCs call check_async_list() directly

Hi Martin, I think this is a better way to do things, but it might be better to submit this patch against the current CVS rather than against CVS+previous patch.

ReadFile and WriteFile in overlapped mode
by Jacques Gelinas 05 Apr '02

05 Apr '02

I have been looking at those two functions and some specs. My understanding is that those function do not work at all in overlapped (async mode). Currently (latest stuff in CVS), both function handle overlap mode like this a) Give it a try in synchronous mode using a combination of pread/read and pwrite/write. b) If not enough bytes were read or written, a request is sent to wineserver to perform and asynchronous operation. This request always fail. (don't know why yet). There is two problem here. If step a succeed, no event will ever be generated since step be is not performed. Application doing the following sequence ReadFile .. WaitOnSingleObject will wait forever. Some borland Builder classes do this My understanding is that step a should never be done and only step b. Is that correct ? Now, why step b is failing is another story.

DeviceIoControl
by Laurent Pinchart 05 Apr '02

05 Apr '02

Hi everybody, I need to add support for a currently unsupported VxD, and I'm quite puzzled by the way that DeviceIoControl currently processes the device control requests. DeviceIoControl starts by checking the high word of dwIoControlCode, which is the device type. If the device type is 0, it gets a client ID by sending a get_file_info request to the server, and uses the client ID as the device type. It then looks in the VxD table for a handler for the device type, and calls it if it exists. No problem with that. If the high word of dwIoControlCode is not 0, it checks if the device is a CDROM (by calling GetDriveTypeA). If so, it calls CDROM_DeviceIoControl, and if not is just fails. I was wondering why the same VxD table as for (HIWORD(dwIoControlCode) == 0) wasn't used when the device type in dwIoControlCode is not 0. It seems to be a mistake to me. I was thinking about implementing the following algorithm: - check HIWORD(dwIoControlCode) - if 0, deviceType = GetCliendID( Device ) - if ! 0, deviceType = HIWORD(dwIoControlCode) - look for a VxD handler in the VxD table using the deviceType. - call the handler if it exists, fails otherwise This leaves out the special case for CDROM_DeviceIoControl. Could anyone explain to me why that special check is needed, if it is ? Thanks in advance. Laurent Pinchart

Review - Winnt.h warning patch for mingw32
by Steven Edwards 05 Apr '02

05 Apr '02

This shuts up some compiler warnings on mingw but I don't know if my syntax is right. I know the rules about ifdef and ifndef but you guys said there was exceptions for the compilers so I figured I would check. Like I said I am still learning here so if this isnt right please flame away. Mingw32 currently lacks a good ./configure system as Msys wont see dlltool/wrap so I don't really have another option other then using my own makefiles for now. There is only about 4 or 5 other places I have found where mingw differs from normal GCC.

SetCooperativeLevel
by Tels 05 Apr '02

05 Apr '02

-----BEGIN PGP SIGNED MESSAGE----- Moin, [crosspost to both wine lists] I am preparing a patch for DirectDraw::SetCooperativeLevel and friends: Some questions from a newbie, so please bear with me: ddraw/user.c has comments like these: /* GetDisplayMode: generic */ /* GetFourCCCodes: generic */ /* GetGDISurface: ??? */ /* GetMonitorFrequency: generic */ /* GetScanLine: generic */ /* GetSurfaceFromDC: generic */ /* GetVerticalBlankStatus: generic */ /* Initialize: generic */ /* RestoreAllSurfaces: generic */ /* RestoreDisplayMode: generic */ /* SetCooperativeLevel: ??? */ * What does the "generic" stand for? Return value? Function class? * It seems that SetCooperativeLevel associates a "value" (or more than one) with the givenwindow handle and TestCooperativeLevel let's you later check this status. Where would I store such a "global" value? * If I understand it correctly, the directx stuff is done by transgaming. Their licence differs from the "normal" wine. (I am really unsure how all these things play together even after readin codeweavers.com, winehq.com and transgaming.com). So, if I send in a patch for that, should I send it to wine-devel-patches? wine-devel? winex-devel? Under what license would it fall? Or does that not matter? I have no idea what hidden snatches are in the transmeta licence, so I would like to use the LGPL. ;) Is there a problem with that for the transmeta guys or for you wine guys? Or would it fall automatically under the transmeta licence, since I am patching their source anyway? (You can tell I am confused ;) * Also, since I am a bit CVS challanged (newbie, I told you ;), is it okay to add my files directly in the CVS source tree with vi(m) and then send you a diff -u patch? Or do I need some CVS magic to do locally? Or just keep the file outside the CVS and then send a patch? Thanx in advance, Te"Wine, I am coooominng!"ls - -- "Why do you go so slowly?

cool font viewer... might make good test case
by Dan Kegel 05 Apr '02

05 Apr '02

FYI... My wife is a Windows user who loves fonts. She never found good free font viewing utilities until today; now she's raving about 'font xplorer lite'. Since it's a free download, it might make a good testcase for Wine's font support. It's at http://www.moonsoftware.com/freeware.asp but I haven't tried it yet. - Dan

Hi, > I have been looking at those two functions and some specs. > My understanding is that those function do not work at all I haven't tested the current CVS lately, but i can assure you that ReadFile and WriteFile did work at some fairly recent time :-) You may be correct that they do not work in *exactly* the right way, but for most cases they do work. > ever be generated since step be is not performed. Application > doing the following sequence > ReadFile > .. > WaitOnSingleObject > > will wait forever. Some borland Builder classes do this No, it won't because asynchronous reads can be processed during on-alertable waits. The application must call WaitForSingleObject eventually to see f the overlapped operation has finished. > My understanding is that step a should never be done and only > step b. Is that correct ? We need to check if data is pending before returning RROR_IO_PENDING because some applications do this: WaitCommEvent(hComm,&ev,&ov); WaitForSingleObject(ov.hEvent); ClearCommError(hComm,NULL,&cs) len = cs.cbInQue; if(!ReadFile(hComm,buf,len,&count,&ov)) FATAL() You're right that the way wine currently handles this is not erfect, but it will only fail if multiple overlapped operations re done at the same time. Martin Wilck is currently fixing this. > Now, why step b is failing is another story. > > Comments ? It's not perfect, and you're welcome to fix it if you want.
