wineserver request size
by Eric Pouech 26 Feb '02

26 Feb '02

how to handle large wineserver request structure ? I've been working on adding the dwFillAttribute handling to CreateProcess (and passing between parent and child) while I was at it, I also added all the other fields (window geometry, console title/size...) at the end the two requests used in the process (new_process and init_process) are larger than the fixed request_max_size structure (80 bytes would be needed) so, what's the preferred way of handling this: 1) bump the request_max_size to the needed size (but all requests will be penalized about it) 2) remove the request_max_size (therefore aligning the size of the request on the one of the biggest available) 3) try to compress the structure fields (most of the data are 32 bits, whereas they would fit in 16 bit fields) 4) store the data above the 64 bytes into the variable part of the message (but that would break the current structure scheme) A+

Native DDE problems
by List vmn 26 Feb '02

26 Feb '02

Hi! I started using wine (wine-20020122 compiled from source tarball) a couple of weeks ago to run a store-point-of-sale application. The idea is to port this windows application to linux. Before porting, we decided to check if the app could be emulated on linux with wine or recompiled with winelib. This is also necessary to run proprietary windows DLLs from third parties such as credit card companies that bind the application to specific hardware. The software uses a lot of external hardware such as printers, barcode scanners, special keyboards etc. These hws usually communicate through the serial port. Another important feature of the software is the use of DDE - Dynamic Data Exchange from the windows API. The application is broken into at least two executables that communicate through DDE. The http://www.winehq.com/News/status.html states that the implementation of the serial/parallel port is 90% complete but that DDE is still being implemented by Eric Pouech and not functional. After reviewing the manuals and spending a few days on trial runs, I decided to try and bring in the native DDEML.DLL and see if the exe´s would communicate. QUESTION: Should this native windows library work under wine, has anybody tried this? When I tried running the software with the native DDE engine (from Win98), I get DDE errors and a warning saying that DDE is not functional yet. This is expected as reported by the status.html page. When I tried running the software with a setup that only the DDEML.DLL was native, the program crashed with an exception. I tried running the program with several debug channels but couldn´t detect the problem. The only thing learned was that the program seemed to be crashing inside USER.DLL builtin code. I then tried several different native/builtin setups using mainly the following DLLs: Native DLLs DDEML.DLL OLE32.DLL COMCTL*.DLL COMDLG*.DLL SHELL.DLL SHELL32.DLL I even tried bringing in USER and USER32. Some of these setups were documented not to work and didn´t. Everytime I got a setup that seemed to work, the software would crash with basically an exception or page fault. I then decided to use winedbg. I was able to get a stack trace of the software at the time of the exception. It is at the end of this email. I also put a complete run of winedbg --debugmsg +msg 'c:\sw\store.exe' in http://admin.vmn.com.br/wine/out.txt From the trace it seemed that USER builtin in code was not yet finished and handling correctly DDE messages or had a messaging bug related to DDE or not. I read the functions in c code from the trace and couldn´t see any obvious problems. They seemed complete and finished. QUESTION: Is the builtin USER.DLL complete? QUESTION: Should it interact correctly with DDEML.DLL? If DDEML.DLL and USER.DLL were communicating through COM then they should interact correctly but since DDE is a protocol dating back to win3.1, probably older than OLE and COM, maybe they don´t. I have thought of reworking the original software to use SOCKETS but this is quite a lot of work. I am new to wine so I may be missing something obvious. Thanks in advance for any help.

Hi, I have implemented 2 procedures to set the language used by Notepad at startup. Now it selects language by using string key "Language" under HKCU\\Software\\Wine\\Notepad. Restore of the language functions now. But I'm new in Windows coding so I don't know which procedure is called when I click on an item in the Language menu.So saving the language in the registry is not called.The procedure is ready to use but never called.

Out of process COM objects & Installshield v6
by Sander van Leeuwen 26 Feb '02

26 Feb '02

Hi, What's the current state of OOP COM objects in Wine? I've noticed a lot of related changes, but have yet to find an InstallShield 6 installer that works. (I did copy the stdole*.tlb files to the windows & system directory) After porting the OLE changes to Odin, I tried the Java 1.4 installer. It fails with error 0x80070057 (CoMarshalInterface; failed to marshal interface) Trying the same installer in Wine (built from latest CVS) results in the same error There's a fixme for NdrDllRegisterProxy for the same GUID that fails in CoMarshallInterface. Perhaps that's the cause. Before I start debugging this, I'd like to know if it is supposed to work at all. Thanks, Sander

About that eeevil library naming decision...
by Andreas Mohr 26 Feb '02

26 Feb '02

Hello all, I've just had prime evidence of yet another library naming conflict: libuser.so (which is in package libuser-0.32-1). (installed as /usr/lib/libuser.so) Other examples would be libole.so or libavifile.so. So could we please *finally* rename the wine libraries to libwineuser.so or maybe even better libwine_user.so ? Thank you very much... Yeah, people told me that wine libraries would be in separate directories anyway, so no need for that naming. But believe me, I HATED that decision from day 1. Packagers simply won't always choose a separate directory for wine libraries. (especially for "global" installs without a wrapper script) Thus there'll be lots of trouble for some people. -- Andreas Mohr Stauferstr. 6, D-71272 Renningen, Germany Tel. +49 7159 800604 http://home.nexgo.de/andi.mohr/

DTR Flow Control
by Michael Cardenas 26 Feb '02

26 Feb '02

Is DTR flow control supported? There's a comment in comm.c in SetCommState that says it's not, but EscapeCommFunction has a SETDTR case and a CLRDTR case. Below are the lines I'm talking about. I'm working on an app that asks for DTR flow control and uses overlapped IO when using a modem. It establishes a modem connection, but then it can't send any data over the connection. I'm using an external modem on a serial port. ------------------------------------------------------------------------ if (lpdcb->fDtrControl == DTR_CONTROL_HANDSHAKE) { WARN("DSR/DTR flow control not supported\n"); } comm.c line 1069 ------------------------------------------------------------- case SETDTR: TRACE("SETDTR\n"); #ifdef TIOCM_DTR direct=TRUE; result= COMM_WhackModem(fd, 0, TIOCM_DTR); break; #endif comm.c line 548

Any simple one. >> So I can see which process I should follow to get the program properly built. >the debugger is a pure winelib app, which heavily uses the console, so >you can copy the Makefiles from it >(in debugger directory from the source) I found a little application in wine directory, wcmd, that uses Win32 console functions, and specifically GetStdHandle. I though it will be easier to control that the debugger. I built the following makefile, based on the Makefile.in in wcmd source code directory: ----------------------------------------------------------------------------- DIRWINE = /opt/wine INCL_WINE = -I$(DIRWINE)/include/wine ### Dependencies: WCMD_dependencies = \ batch.obj \ builtins.obj \ directory.obj \ wcmdmain.obj # Build wcmd : $(WCMD_dependencies) c++ -o wcmd -L$(DIRWINE)/lib \ batch.obj \ builtins.obj \ directory.obj \ wcmdmain.obj \ -lkernel32 -lntdll -luser32 -lshell32 ### Rules batch.obj: batch.c gcc $(INCL_WINE) -c -o batch.obj batch.c builtins.obj: builtins.c gcc $(INCL_WINE) -c -o builtins.obj builtins.c directory.obj: directory.c gcc $(INCL_WINE) -c -o directory.obj directory.c wcmdmain.obj: wcmdmain.c gcc $(INCL_WINE) -c -o wcmdmain.obj wcmdmain.c ------------------------------------------------------------- It builds properly wcmd executable. But running it I get a Segmentation fault (core dumped). When running it using gdb, I find the exception before main in libshell32.so library. What am I going wrong ? Is it possible that I have a wrong or an outdated wine version ? I took it from codeweavers.(codeweavers-wine-20011108-5.i386.rpm). If I have to get an update, I'd like to know if there's an already built version for RH6.2 to avoid rebuilding wine package, because Codeweavers hasn't refreshed wine versions and I don't find other built versions for RH6.2. Many thanks for helping. Ignasi Villagrasa.

Re: DTR Flow Control
by Mike McCormack 25 Feb '02

25 Feb '02

Hi Michael, > Is DTR flow control supported? No. However the Win32 API uses very confusing names, so make sure the app is really asking for DTR/DSR flow control. DTR_CONTROL_ENABLE does not mean DTR/DSR flow control is enabled, it means turn on the DTR line permanently. Only DTR_CONTROL_HANDSHAKE means the serial port should use DSR/DTR handshaking. (AFAIK, DTR_CONTROL_ENABLE and DTR_CONTROL_DISABLE flags are not correctly handled in the current wine... they should actively turn on or turn off DTR). Additionally, there were some problems in the GetCommState/SetCommState code that saw DTR_CONTROL_HANDSHAKE accidently turned on, so make sure that it is really the application that is requesting it. As Marcus pointed out, the linux kernel itself does not support DTR/DSR flow control, but given the time and motivation, we could solve the problem if you really need to make this work...
