Relocate error
by Fabian Cenedese Sept. 10, 2003

Sept. 10, 2003

Hi I worked with wine about six months ago. Except some minor errors my app worked quite good in wine. Then I didn't have time anymore. Now I tried again with the newest wine from cvs. But now I can't even start my app anymore. Wine gives me this error: err:virtual:map_image FATAL: Need to relocate module from addr 40000000, but there are no relocation records wine: could not load 'C:\IMD\Bin\Imd.exe' as Win32 binary I looked in the archives and the only messages concerning this error were at least two years old stating that this error has been fixed long ago. I didn't change this link address in my app (VC6), it has been there even before I started with wine at all. But when I change this address to say 0x48000000 then it works. So is there something else on this address? I know six months is a long time and a lot happened this year. But does anybody know if this is a real error? What could have introduced this behaviour as it worked a few months ago? Thanks Fabi

DRIVE_GetUnixCwd and drives other than the current one
by Troy Rollo Aug. 12, 2003

Aug. 12, 2003

It appears that Wine is storing and using a "current directory" for each DOS drive. According to some testing we have just done on Windows 2000 and Windows 98, Windows only stores a current directory for the current drive. "But CMD.EXE seems to remember drives, and their children too", comes the reply. Well, sort of. The documentation for CreateProcess talks about environment variables used to hold the current directory for each drive, with an environment variable with a name of the form "=C:" having the value, say "C:\WINDOWS". That documentation suggests you must make sure all these environment variables are set if you construct a new environment block, and that you need to get the values of them using "GetFullPathName". Shock, horror, the Windows documentation is wrong. What actually happens is that CMD.EXE and COMMAND.COM independently set those environment variables when you change directories in those shells. SetCurrentDirectory has no effect on those environment variables - either in the current process or in child processes. It is the responsibility of the application to set them if it wants the children to have access to its current directory on drives other than its current drive. However, SetCurrentDirectory("D:") (assuming a starting point of drive "C") will read those environment variables to determine which directory of drive "D" to go to. You can even 'SetEnvironmentVariable("=D:", "\\foo")' to make the next 'SetCurrentDirectory("D:")' end up in "D:\foo". GetFullPathName also picks up the environment variable if the path requested is not on the current drive (although it also checks that the path is valid, so 'GetFullPathName("A:\\", ...)' will rattle drive A if drive A is empty). If there's no environment variable, both GetFullPathName and SetCurrentDirectory assume "x:\". If the drive in question is the current drive, SetCurrentDirectory and GetFullPathName both ignore the environment variables and use the value from GetCurrentDirectory. So, for example: // Start with no "=D:" variable in environment SetCurrentDirectory("d:\\bar"); SetCurrentDirectory("c:"); SetCurrentDirectory("d:"); // Current directory now d:\ SetCurrentDirectory("d:\\bar"); SetCurrentDirectory("c:"); SetEnvironmentVariable("=D:", "\\foo"); SetCurrentDirectory("d:"); // Current directory now "d:\\foo"; SetEnvironmentVariable("=D:", "\\bar"); SetCurrentDirectory("d:"); // Current directory still d:\\foo The Borland C++ run-time libraries have code in their chdir functions that sets these variables, but it's inside a "#if 0" section, presumably reflecting an attempt to be compatible with MSC. I'm not aware of anything that relies on this perverse behaviour, so whether Wine needs to be adjusted to mimic it may be an open question. It is probably of more interest to people who want to pass an environment block to CreateProcess. If you're doing that, ignore what the documentation says about including "=C:" & etc environment variables in the environment block - simply start with the environment block returned by GetEnvironmentBlock and make the desired changes, ensuring the block is sorted according to instructions I gave previously on one of the Cygwin mailing lists.

can't redirect stdout?!
by Dan Kegel Aug. 12, 2003

Aug. 12, 2003

OK, so with the normal X11 driver, you can no longer redirect stdout from commandline apps under Wine; the output just vanishes if you try to send it to a file. That's rather unacceptable dain bramage, if you ask me. - Dan -- Dan Kegel http://www.kegel.com http://counter.li.org/cgi-bin/runscript/display-person.cgi?user=78045

Is wine a debugger?
by Dan Timis Aug. 12, 2003

Aug. 12, 2003

I am trying to load a security Windows dll that does not run under a debugger. When I load the dll I get a SIGTRAP, and then wine breaks in its debugger. My understanding is that if I run wine as opposed to winedbg I am not running under a debugger. But, if there is a crash or some other exception wine will start a debugger. I sent some memory dumps to the developer of the security dll, and he said that it behaves like it was running under a debugger. He's question was something like does wine have an always "on" debugger? I would appreciate any help. Thanks, Dan Timis Muse Research, Inc.

My confidence in that part is not very good, since it doesn't make sense to have different calculations for the horizontal and vertical bars. So if someone were to do some simple testing to verify/correct that function, it would be a good thing. All of the rest of the patch sets the rest of the dimensions of the control based on the length of the thumb and the size of the window, which is how Windows does it. That part I tested extensively, and am very confident is correct.

Licensing Question
by Anthony Tuininga July 31, 2003

July 31, 2003

The MingW32 project is developing its own set of Windows headers under a different license than Wine (which uses LGPL, right?) and I have noticed (using both projects) that the Wine headers are more complete in a number of areas. I was wondering if it would be acceptable to use the Wine headers as a source for filling in gaps in the MinGW32 headers? In essence, would the Wine group be willing to allow this cross pollination since (clearly) it would be a violation of the licenses as they stand today. Any thoughts on this? Or am I treading into a minefield?? :-) -- Anthony Tuininga anthony(a)computronix.com Computronix Distinctive Software. Real People.

Unhandled exception (wine-20030709)
by Magnus Solvang July 30, 2003

July 30, 2003

(I posted this to the wine-users-list a week ago, but didn't get any respons) I just tried to install wine for my first time. Redhat 9.0, kernel 2.5.73. Downloaded the rpm-binary, but when trying to start notepad.exe, it looped with a message like: wine: Unhandled exception (thread 01f9), starting debugger... Could not stat /mnt/fd0 (No such file or directory), ignoring drive A: While looping it started nearly 255 processes (max PTYs?), before the machine halted. I did this before modifying my config-file (using the default one). After adjusting the config-file, I no longer got any error-messages, but the same thing happened.

fontview.exe...
by Jonathan Wilson July 30, 2003

July 30, 2003

Its used by windows to display fonts before and after installation. And I know of at least one setup program (might have been a Corel app, I forget) that displays a long list of fonts which you can select from to install and then uses fontview.exe (I think its fontview.exe, it loks very similar anyhow) for previewing the fonts (so you can see what they look like before they are installed). Anyone want to comment on this: 1.does anyone else remeber the app and/or the dialog? 2.does anyone know if it really is fontview.exe? 3.does wine need a fontview.exe? and 4.if I was to code a fontview.exe, would it be of use to anyone (wine, reactos etc)?

Strange behavior on build
by David D. Hagood July 30, 2003

July 30, 2003

I'm having a strange behavior trying to build Wine on my machine at work (which is a modified RH7.3 machine): First of all, if I attempt to do a standard CVS checkout followed by a make depend, the make depend failes with a "dlls - no such directory" error, even though it exists. Changing SHELL=/bin/sh to SHELL=/bin/bash in Make.rules and re-running configure fixes this, but then I get stuck in a loop building - it looks like the makefile starts building the dependancy "wine", then builds "libs", then decides it needs to build "wine" to build "libs" and starts that, then builds "libs".... I'm at a bit of a loss to explain the behavior, so does anybody have any good suggestions?

API tracking and documentation
by Steven Edwards July 29, 2003

July 29, 2003

Hello, The ReactOS project is interested in making a change to WINE the function commented that would make API tracking a little nicer. We have implemented a web page like the mono project has that shows the implemented and unimplemented functions in the API. Will the WINE project accept patches to the comments to support this type of tracking system? It would be nice because you guys could implement the same thing on your website. If the answer is no it is REALLY going to be a PITA for us to diff our sources to yours for every function. Please take a momenet to look at the site and how it works. http://reactos.wox.org/index.php?page=apistatus Here is the documentation for how we do it. Abstract Explains what tags are and how to use them. TABLE OF CONTENTS * 1 Overview * 2 MS API compatibility 1 Overview We define tagging a function as the process of associating metadata with a function. We define a tag to be a piece of information that has a well-defined meaning. A tag has one attribute - a name. The name of a tag always begin with the at sign (@) and it can include only the letters a-z and digits 0-9 and the underscore (_). Tagnames are case-insensitive. In the future a tag could have one more attribute - a value, but this is currently not needed. In ReactOS, tags are currently only used to track compatibility with Microsoft APIs, but it could be used for so much more. Tags are applied to functions by including them in a comment just before the function. Eg. if you have a function called MyFunction, then you can tag it with the tag @mytag like this: /* * @mytag */ VOID MyFunction() { } 2 Microsoft API compatibility Two tags are defined to track compatibility with Microsoft APIs. @implemented and @unimplemented. Apply @implemented to functions which match and behaves like a Microsoft API. Use @unimplemented to functions which match, but does not behave like a Microsoft API. The regenstat tool (located in reactos/tools/rgenstat) will parse the source code for these tags and generate an xml file containing functions that have these tags. The xml file can be processed by the rapistatus.xsl xml stylesheet (located in reactos/tools/rgenstat/web) to create an html file suitable for display using a browser. __________________________________ Do you Yahoo!?

WineHQ website (lostwages) url changes
by Jeremy Newman July 29, 2003

July 29, 2003

I spent some time today working on the lostwages codebase. I finally discovered how to get PHP to see the PATH_INFO without getting a 404. Seems you need to put "AllowPathInfo On" in the .htaccess. In doing so, I can get rid of the ugly ?page=about urls and instead use /site/about. I updated .htaccess to catch the old urls and put them to the new style. NOTE to template authors, if you want to put a relative link in the site from now on, use {$root} to have the site put the correct path in for you. For example, <a href="{$root}/site/about">About Wine</a>. This also works for images: <img src="{$root}/images/foo.jpg"> -- Jeremy Newman <jnewman(a)codeweavers.com> CodeWeavers, Inc.

how cards.dll works
by Jonathan Wilson July 29, 2003

July 29, 2003

After finding out that certain things I did when coding cards.dll (such as studying the complete code in a disassembler) mean that any code I write for it a potential "derivitave work", I have come up with a descrition that is (hopefully) detailed enough to enable someone else with windows GDI programming experience to write cards.dll for wine but (hopefully) not detailed enough to be considered a "derivitive work" The folowing files can be made available to whoever ends up working on cards.dll: 1.cards.spec, a ready made spec file for the dll 2.cards.rc, a RC file containing the card bitmaps (which are licenced under a licence that gave permission to use them) and also the card back bitmaps that were sent to me before (to whoever ends up working on this, feel free to modify the images if you dont like them :) 3.makefile.in ready made for the dll and 4.cards.h which contains the publicly documented interface to cards.dll (which I pulled from various info documents found on the net) IANAL but I dont think that any of these could be claimed to be covered by that "derivitave work" thing, if they are, please do tell me. This document explains the workings of cards.dll (version 5.00.2134.1 from windows XP SP1) Cards.dll exports 7 different functions. These are: cdtInit cdtTerm cdtAnimate cdtDraw cdtDrawExt DllMain and WEP cdtInit takes 2 int * variables. It should return TRUE if the initalization was sucessfull and FALSE if it was not. It is a place to do any initalization you require (depending on for example if you want to preload the resource bitmaps or whatever). It should return the x and y size of the card bitmaps in the 2 variables. For the cards I am using, the x size is 71 and the y size is 96 (which just happened to match up with the size of microsofts cards which is good) the main purpose of DllMain is to store the HINSTANCE of the cards.dll to use later when the bitmaps are loaded WEP is a holdover from when cards.dll was a 16 bit dll and doesnt actually need to be implemented (since its never called by 32 bit windows) cdtTerm is where you undo anything you did in cdtInit (such as unloading any preloaded resources) It takes no parameters and returns nothing. cdtAnimate is supposed to handle animations for the card backs but since the backs we are using dont animate, it can just return TRUE (hence why the resource file I wrote returns the windows XP version number since XP doesnt have animated backs either) As for parameters, it takes a HDC, an x and y position and a frame number (each individual microsoft back has a specific number of frames and applictions tend to hard-code these values) cdtDraw basicly calls cdtDrawExt passing the default size of the card bitmaps as the x and y size parameters The real work is done in cdtDrawExt This function takes: a HDC (for the screen window to draw the card on) an X positon and a Y position to draw the card at a card number (cards.h lists the different values) a mode number (again cards.h lists the different values) and a RGB background color What the function does depends on the value of the mode. If the upper bit of md (which is an int) is set, then it shouldnt save and resore the corner pixels (as explained below) modes greater than 7 should (as far as I can tell) do nothing. mode 0 is "draw face card" mode 1 is "draw back" mode 2 is "draw highlighted face card" mode 3 is "draw empty card spot" mode 4 is "erase card" mode 5 is "draw empty card spot but doesnt paint background" mode 6 is "draw red X card" and mode 7 is "draw green O card" all modes use the same "drawing logic" except for mode 4 which doesnt draw any bitmap. You need a resource ID and a raster OP to do the drawing For modes 0 and 2, the resource ID uses this formula resource id equals ((((card number shl 2) mod 0dh) plus ((card number and 3) times 0dh)) plus 1) For mode 1, the resource ID is just the card number For modes 3 and 5, the resource ID is 53 (the resource ID of the empty card spot graphic, also the contant hb in cards.h) For mode 1, the resource ID is just the card number For mode 6, the resource ID is 67 (the resource ID of the card with the red X on a green background graphic, also the contant xb in cards.h) For mode 7, the resource ID is 68 (the resource ID of the card with the green O on a green background graphic, also the contant ob in cards.h) and mode 4 doesnt use any ID since it doesnt draw anything. For the raster OP, all modes use SRCCOPY except for: mode 2 which uses NOTSRCCOPY and modes 3 and 5 which use SRCAND Also, if the mode is 0, the background color is set to white (0xFFFFFF) before drawing. And after drawing, if the card is a red card (resource IDs 0x0E to ox17 and 0x1B to 0x24), it paints over the boarders of the card using PatBlt and the BLACKNESS rasterop. If the mode is 3 or 4, it creates a solid brush using the background color, uses SetBrushOrgEx to set the brush origin to the screen DC origin and then uses PatBlt to paint over the area of the card using PATCOPY. If the mode has the top bit clear (as explained above) and the size matches with the default card size, before drawing, it saves the corner pixels of the cards (the card bitmaps I am using have one pixel in each corner) and then restore them after drawing. To do the actual drawing, you need to load the bitmap resource into memory and load the resulting HBITMAP into a memory DC. You also need to set the background color of the screen DC to whatever was passed in (unless its mode 0, in which case its 0xFFFFFF as explained above). And then, you need to copy the data from the memory DC to the screen DC using either BitBlt or StretchBlt as appropriate. Remeber to free all the GDI resources (bitmaps, memory DCs etc) that you used. And also to restore the background color to whatever it was before you changed it. If the function is a sucess, you return TRUE. If the function is a failure (e.g. a GDI function call fails), you return FALSE. Hoepfully someone can use this information to implement cards.dll in a way that is legally safe.

I also stayed in late and upgraded our Mailman to ver 2.0.13 from ver 2.0.0. Let me notice if you notice anything unusual happening in the next few days. Also, I am considering putting a SpamAssassin filter into our Mailman using info from this page: http://www.daa.com.au/~james/articles/mailman-spamassassin/ Anyone against this idea? -- Jeremy Newman <jnewman(a)codeweavers.com> CodeWeavers, Inc.

He's > question was something like does wine have an always "on" debugger? Just in case someone else runs into this problem, the fix is to run wine as nt not as win98.
