DOSMEM_Init VirtualProtect fails
by vkxzjq6lg＠cswebmail.com 10 Dec '02

10 Dec '02

To further my porting work, I've patched my copy of DOSMEM.C like this: else if (dos_init && !already_mapped) { if (DOSMEM_dosmem) { ERR( "Needs access to the first megabyte for DOS mode\n" ); ExitProcess(1); } MESSAGE( "Warning: unprotecting the first 64KB of memory to allow real-mode calls.\n" " NULL pointer accesses will no longer be caught.\n" ); /* James Day added the if/FIXME/return false around this VirtualProtect because OzWin on my AMD K6-3 gave this result: wine --debugmsg +dosmem ozwin2 fixme:toolhelp:InterruptRegister16 (0000, 0x26f00ba), stub. Warning: unprotecting the first 64KB of memory to allow real-mode calls. NULL pointer accesses will no longer be caught. fixme:dosmem:DOSMEM_Init Failed to unprotect first 64KB of memory. init=1, done=1, mapped=0 fixme:toolhelp:InterruptUnRegister16 (0000), stub. */ if ( ! VirtualProtect( NULL, 0x10000, PAGE_EXECUTE_READWRITE, NULL ) ) { FIXME("Failed to unprotect first 64KB of memory. init=%d, done=%d, mapped=%d\n", (int)dos_init, already_done, already_mapped); return FALSE; } /* copy the BIOS and ISR area down */ memcpy( DOSMEM_dosmem, DOSMEM_sysmem, 0x400 + 0x100 ); NtProtectVirtualMemory is returning STATUS_INVALID_PARAMETER to VirtualProtectEx and DOSMEM_Init wasn't handling this failure gracefully - the memcpy was tripping the debugger and falling flat, taking the application with it. Anyone got any better ideas? Want more information on what's happening, like which of the STATUS_INVALID_PARAMETER cases is happening?

How to find out if file is loaded?
by Klaus Niederkrueger 09 Dec '02

09 Dec '02

Hello, I would like to know the following: I start some program with "wine -debugmsg +file" and I get quite a lot of times trace:file:CreateFileW L"tiles\\TS01.bmp" GENERIC_READ FILE_SHARE_READ FILE_SHARE_WRITE OPEN_EXISTING attributes 0x80 trace:file:CreateFileW returning 0x58 trace:file:_lopen ('tiles\TS01.BMP',0000) trace:file:CreateFileW L"tiles\\TS01.BMP" GENERIC_READ FILE_SHARE_READ FILE_SHARE_WRITE OPEN_EXISTING attributes 0x0 trace:file:CreateFileW returning 0x58 trace:file:ReadFile 0x58 0x406d2690 14 0x406d264c (nil) trace:file:ReadFile 0x58 0x406d2668 40 0x406d264c (nil) trace:file:ReadFile 0x58 0x406d26a4 1024 0x406d264c (nil) trace:file:_lclose handle 88 So it seems to me that the file tiles\TS01.BMP is loaded, but when I use "ltrace wine ..." I don't find any output regarding this file. Why is that? Thanks for any answer Klaus

Re: strcat+strcat+strcat == baaad
by Morten Welinder 09 Dec '02

Unless we're talking an inner and very intensive loop, all this is a bit silly. However, assuming that it does make sense, sprintf variants are not part of the answer. They're interpreted and var-arg type, both of which are little good for efficiency. More like something along these lines: char *tmpdst = dst; strcpy (tmpdst, src1); tmpdst += strlen (src1); strcpy (tmpdst, src2); tmpdst += strlen (src2); strcpy (tmpdst, src3); tmpdst += strlen (src3); ... strcpy (tmpdst, srcN); tmpdst += strlen (srcN); ... This works even better when the strlen calls have known results. Of course, nothing keeps the compiler from noticing a certain pattern of sprintf calls can producing an equaivalent of the above, but right now gcc will not do that if I recall correctly. Morten

Non latin fonts and non local fonts
by Shachar Shemesh 09 Dec '02

09 Dec '02

Hi list, http://bugs.winehq.com/show_bug.cgi?id=1157 It appears that when I'm copying the Windows fonts to C:\windows\Fonts, setting LANG to he_IL is all it takes for Hebrew to be displayed in edit controls and dialog boxes. When I try to copy the exact same fonts to /usr/lib/X11/fonts/windows, and adding them to the XF86Config fonts dir, and running ttmkfdir, no go. The fonts are available to Wine (and each is enumerated multiple times in the fonts dialog), but Hebrew is not displayed by default. Sometimes, when I force the CHARSET to HEBREW_CHARSET, I get Hebrew after all, but I'm not at all sure the same font is used then. In addition to this problem, I was wondering why we no longer enumerate the X fonts the moment there is ONE font file in c:\windows\Fonts? Is there a reason for them to magically disappear? Shachar

Well, no, the cost is linear. It would only be quadratic if the number of strcat calls depended on the length of the string. > It's more efficient to do: > > sprintf(foo, "%s%s%s%s%s%s", bar1,bar2,bar3,bar4,bar5,bar6); I seriously doubt that sprintf would be faster that a couple of strcats. And I don't think we need to worry about this kind of micro-optimizations right now... -- Alexandre Julliard julliard(a)winehq.com

Disassembly of the adobe svg plugin
by Mike Hearn 09 Dec '02

09 Dec '02

Well, I have about 2 hours now when I can work on trying to get the adobe svg plugin to work in Wine. I have a deadline to meet for Friday that requires the plugin, so if I can't get it working back to Windows it is (it's like a damn magnet). I've already located a mouse bug (problem with my last patch, oops) and fixed it (patch sent), but the lack of render on paint problem still eludes me. Having not got a response to the last email, I'll assume it's OK to try poking about inside the plugin itself to figure out what's going wrong. If anybody has some tips, now would be the time to tell me about them :) I hope this doesn't invalidate any patches I might produce..... -- Mike Hearn <m.hearn(a)signal.qinetiq.com> QinetiQ - Malvern Technology Center

Turkish keyboard Support
by Armish 09 Dec '02

09 Dec '02

Hi all, I tried the latest wine (Wine-20021125.tar.gz) and saw that though it supports the Turkish Keyboard Layout, I cannot write the specail chars of Turkish (Like ı ş ğ � � � ...) Then I found a (Turkish) keyboard.c but still don't know where or how to it? (The keyboard.c is working well with my kernel) What can I do? (The keyboard.c is in the attach. for someone who want to check) Thanks __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.

Re: Turkish keyboard Support

Was this working under Wine-20021031? I have been trying to figure out a similar problem with the Spanish keyboard layout. If this caused a regression for you as well, it means I have been looking at the wrong problem. If you could test with the 20021031 version and compare results, that could be very helpful. -- Jeff S >From: Armish <acemimsi(a)yahoo.com> > >Hi all, >I tried the latest wine (Wine-20021125.tar.gz) and saw >that though it supports the Turkish Keyboard Layout, I >cannot write the specail chars of Turkish (Like ý >þ ð ü ç ö ...) >Then I found a (Turkish) keyboard.c but still don't >know where or how to it?

POSE (Palm OS Emulator) on WINE?
by Bodo Wenzel 09 Dec '02

09 Dec '02

Hi list. Because Sony doesn't provide a Unix source code branch, I tried to run their Windows based POSE on WINE. At first glance it runs, but only until a command of the context menu is chosen. WINE reports an "unhandled exception" and launches the debugger. My question: does anyone heard about how to make POSE run on WINE? Is anyone interested in making them work together? Both are Open Source... Unfortunately I can't because of my lack of time :-( TIA, Bodo
