[PATCH] async IO API, reworked
by Martin Wilck April 8, 2002

April 8, 2002

Hi, Here is a reworked version of the async API patch which I hope is now ready for being applied. Details see below. Regards, Martin PATCH: async-struct.diff Purpose: Modified API for asynchronous IO requests. - separate cleanly between async scheduling and file IO related issues, - make the API compatible with other types of async requests (e.g. for sockets), - remove exports of async IO related functions for DLL separation. ** This patch OBSOLETES these two patches I submitted: ** http://www.winehq.com/hypermail/wine-patches/2002/04/0020.html http://www.winehq.com/hypermail/wine-patches/2002/04/0034.html Note: the cancel_async server request that was in the previous patch (0020.html) was removed (unnecessary). Patch against: Wine CVS 2002/04/05 Test status: Compiles (no errors/warnings). Tested regular file async IO with ReadFile and ReadFileEx (ok). Added files: include : async.h (structs and inline functions for async requests) Modified files: server : protocol.def (add APC type APC_ASYNC_IO, remove func element of register_async request) async.h (remove func element in async struct) async.c (remove references to func element in async struct) thread.c (allow NULL function pointer for APC_ASYNC_IO requests) dlls/kernel : comm.c (use modified API) files : file.c (use modified API) include : file.h (move async stuff to async.h) scheduler : synchro.c (remove functions now inlined through async.h, call_apcs() calls check_async_list() for APC_ASYNC_IO APCs) diff -ruNX ignore CVS/wine/dlls/kernel/comm.c TMP/wine/dlls/kernel/comm.c --- CVS/wine/dlls/kernel/comm.c Wed Apr 3 19:32:56 2002 +++ TMP/wine/dlls/kernel/comm.c Fri Apr 5 11:19:40 2002 @@ -91,6 +91,53 @@ WINE_DEFAULT_DEBUG_CHANNEL(comm);

Log message: Huw D M Davies <hdavies(a)codeweavers.com> The horizontal dialog base unit is calculated as the straight average of a-z,A-Z (tmAveCharWidth is supposed to be a weighted average according to character usage, so we shouldn't use this). Good day! I don't pay much attention to GUI, or care much about it, but I noticed this patch causes my app to display a progress bar (?) with the title folded down into the progress bar, so it looks kind of lame. % xx transferred: Without the patch, it looks more like: % transferred: xx I have no idea what this app looks like in Windows. I have never run it with Windows, and I have no intention to buy Windows just to see, but I think we might not want this bit of code to stay exactly as it is. I will gladly make any kind of traces you would like to see, or I can live with it. The app is in fact obsolete win9x, but it is the most recent version that can work a modem without requiring DUN or RAS or some dam' thing. Hmmm, I wonder if a more recent version has the same problem? Let me check... Regards, Lawson ---oof---

[PATCH] winemaker + DLL paths
by Martin Wilck April 8, 2002

April 8, 2002

I found that winemaker-generated configure scripts bail out with recent CVS versions of wine. The appended patch fixes this. It may be not exactly what the winemaker authors intended, but at least it generates working configure scripts for me.

Running tests on windows
by Geoffrey Hausheer April 8, 2002

April 8, 2002

Last week I submitted a perl script that makes a Makefile (and archive bundle) for building tests on Windows boxes under cygwin. Well, it works fine with mingw too (when using msys at least), but there is a snag. In order to compile tests under Windows, I seem to need to include windows.h before any other .h files. I did this using the '-include' directive in gcc, but it requires knowledge of the absolute path to the windows.h file. This means I need to specify the path in the Makefile, which is completely non-portable (especialy with mingw which doesn't really have a default setup like cygwin does). 1) So it seems I have three options. I can append '#include <windows.h>' to each .c file (either wrapped in #define, or through the perl script) 2) I can include the entire wine /include directory in the archive, and use that 'windows.h' to build against. 3) I can just force the user to edit the Makefile to point to the correct include directory. I don't really like any of these options (though 3 is the the easiest to implement, as this is how it works now) So is there a better solution than the three I've listed? And why won't wine let me include 'windows.h', but under windows it is required? Thanks, .Geoff

winver
by Rizsanyi Zsolt April 7, 2002

April 7, 2002

Hi! I have tried to run my program with --winver nt40. And it was ok But when I started the program by the means of setup.exe (its the autorun program on a cd which detects if the program is already installed, and automatically starts it), then the program was not running like it had got the winver argument. It was looking for VxD only used in win9x mode (the output is same as if I run it without --winver). Interestingly I have also noticed that when I start the program through setup.exe it is not managed, although I have managed mode set in ~/.wine/config I think that the processes created by other executables get the hardcoded options, and not from the configuration. Also winver option in the config file would be useful. Best regards Zsolt Rizsanyi

How to debug an exception handler ?
by Laurent Pinchart April 7, 2002

April 7, 2002

Hi everybody, I have a windows program which raises an exception as part of its normal execution (it tries to call int 0x01). The program setups an exception handler, catches the exception, and resumes it execution after the call to int 0x01. This works fine when run in wine. However, when I try to run the program in winedbg, the debugger catches the exeception, interrupts the program execution, prints a register dump, stack dump & backtrace, and waits. If I continue the execution using 'cont' (after incrementing $eip by 2 to skip int 0x01), the program continues but the exception handler installed bu the user program is not called. I was wondering if it was a bug or a normal behaviour, and if it is normal behaviour, is there a workaround ? Thanks in advance for your help. Laurent Pinchart

As it happens, Juno version 4 puts the title under the progress bar, Transferred xx% and the patch doesn't cause it to fold. Maybe it isn't important, but if you would like to debug Juno version 2 I will be glad to help.
