Re: debugging longman dictionary
by Laurent Pinchart 25 Mar '02

25 Mar '02

I looked at the trace log you attached to your email, and recognised (unfortunately) familiar copy protection output :-( Is anyone working on implementing what would be needed to successfuly run copy-protected softwares ? I ran into the same problems when I tried to play The Longuest Journey with Wine. I disassembled a large part of the code and rewrote it in C to try to understand what was going on. If anyone is interested I can send my work by e-mail (I won't send it to the list as the files are quite big). Basically, the copy protection scheme I studied used the following technique. One of the sections in the PE file is encrypted. The decryption key is generated from the content of the other sections. The process of decrypting the encrypted section tried to detect if a debugger is running, and fails to run properly if so. This results in the inability to decrypt the PE file if the unencrypted section is modified or if a debugger is running. There must be some code to detect if the application CD is genuine but I've never been able to go past the decryption part. To detect if a debugger is running, the following actions are performed (in no particular order): - the code tries to open some files using CreateFileA : "\\.\SICE", "\\.\SIWVID" and "\\.\NTICE". This fails as the SoftICE VxDs are not loaded, so no problems there - it also tries to read/write to the debug registers. this produces an unhandled exception. should be trivial to write an exception handler to support that (right ?) - the code writes binary code to the interrupt vector table (at address 0 - division by 0 handler), and then cause to the division by 0 interrupt handler to be called by dividing a value by 0. - the TIB (Thread Information Block, which address is located at fs:0) is read. The following C code illustrates the technique (which I don't understand :-) bool detect_debugger_from_TIB { char *pTIB; asm ( "mov %%fs:0x18, %", "=g"(pTIB) ); if ( pTIB[0x20] == 0 ) return FALSE; else return TRUE; } - another debugger detection technique uses int 0x68, functino 0x4300. If the content of eax when returning from int 0x68 is not 0x4300, a debugger is present. This is not performed on some NEC Japanese systems, which probably use int 0x68 for another purpose. - the last attempt to detect a debugger uses int 0x01 (enter SMM/ICE mode), which checks if an external hardware emulator is connected to the processor. I haven't been able to understand what the code is supposed to do. There might be some other anti-debugging techniques, I gave up after 2 weeks of disassembly :-) Hope these observations will help someone. Laurent Pinchart

ntfs filesystem
by Lonnie Cumberland 25 Mar '02

25 Mar '02

Hello Again All, I just had another thought and was wondering if someone was working on the NTFS filesystem for Wine? I am guessing that this is what is being used in the Windows2000 and Windows XP as well, right? cheers, Lonnie -- Lonnie Cumberland OutStep Technologies Incorporated EMAIL: Lonnie(a)OutStep.com : Lonnie_Cumberland(a)yahoo.com The Basis Express Virtual Office & Data Backup and Recovery Services URL: http://www.basis-express.com "The Virtual Office without boundaries!!!"

similar WIne projects for MAC?
by Lonnie Cumberland 25 Mar '02

25 Mar '02

Hello All, I am really starting to get involved with the wine project and am trying get up to speed so that I can start to implement some of the FIXME functions as soon as possible. I was just wondering if there was also an type of Wine project that would allow MAC to run on Linux as well, but not in the respect of having to load the MAC os like VMware?

Hack/work-around for cursor problem on sparc-solaris
by Warren_Baird＠cimmetry.com 25 Mar '02

25 Mar '02

Hi all, I've managed to come up with a work-around for the cursor problem on sparc-solaris. What I'm not sure about is whether this should be checked in as a general fix. The problem was that if X11DRV_GetCursor (dlls/x11drv/mouse.c) is called with a NULL CURSORICONINFO pointer, it would explicitly create a completely empty cursor... This doesn't seem like the right thing to do to me - it seems to me much better to create a default cursor from the provided X11 cursor font, and use it. The question is, does anyone rely on this behaviour? From what I've seen of the code, this only happens if there is a problem loading the windows cursors, in which case it would be much more sensible to show a default cursor than no cursor at all. If someone is relying on this to create an empty cursor, it might be better for them to explictly create a CURSORICONINFO that creates an empty cursor. What do people think - should I submit this as a patch? Warren

Duplicated functions?
by Warren_Baird＠cimmetry.com 25 Mar '02

25 Mar '02

Hi all, I've been digging around trying to track down my cursor issues, and I noticed that there seem to be 3 identical implementation of the function find_entry_by_id implemented in dlls/user/exticon.c, dlls/version/resource.c, and loader/pe_resource.c. Is this intentional? It seems like the danger for the the functions to get out of sync is quite high (especially since there aren't sufficient comments indicating that other versions need to be updated). If it isn't intentional, I'll open a bug about it (I don't really have time to fix it right now), otherwise I'll add a couple of lines of documentation indicating that there are multiple versions that need to be updated to each of the functions comments.

pthreads issues?
by Chris Morgan 25 Mar '02

25 Mar '02

I've been working on a wine driver for the jack audio server, jackit.sourceforge.net. The concept of the server is to open audio ports and setup a callback function that will be called whenever the server needs more audio data. Everything works fine until the point of starting up the client and starting the calls to the callback function. With the latest cvs version of the jack server and some changes to the driver I haven't been able to get the driver to start the client up successfully, it just hangs after the below first two pthreads errors although I suspect this may be due to the same issues as before. Previously only about 50% of the time would the client be started up correctly, the other half of the time it would report failure to connect to the server and I would have to kill wine and restart a few times before it finally would work. I got errors like below: ~/c/Program Files/winamp$ wine Winamp.exe FIXME:pthread_cond_init FIXME:pthread_cond_signal FIXME:pthread_cond_wait fixme:ntdll:RtlNtStatusToDosError no mapping for 00000102 It appears that something went wrong between wine and wineserver communication and that strange 102 got stuck in there. I've also had strange X errors and another person reported: "I'm having problems getting jack to work with a GTK+ app. 3 times out of 4 when I start I get: engine has shut down socket; thread exiting Xlib: unexpected async reply (sequence 0x102)!" Any ideas? Thanks, Chris

Cursor issues on sparc-solaris
by Warren_Baird＠cimmetry.com 25 Mar '02

25 Mar '02

Hi all, I alluded to this in a post on Friday, but I'm going to ask about it explicitly now. In the sparc-solaris port, most bitmaps are now showing up fine (with a few fixes in wrc), but when the mouse enters a wine window the mouse cursor disappears. The mouse still works if you can figure out where to click it. I've been tracing through the code, trying to figure out what is going wrong. with a breakpoint in LoadCursorA, I've stepped down through the resource loading code, until I get to PE_FindResourceW. It calls find_entry_by_nameW, which calls find_entry_by_id. The inputs seem fine, but the resource id (0xC) doesn't show up in the IMAGE_RESOURCE_DIRECTORY, which has only 3 entries, with ids 4, 5 and 6... I'm afraid I'm at a bit of a loss so far. My instincts say that the id is fine, and that something is breaking during the loading of the image resource directory - I'm trying to trace back where the image resource directory is populated, but I haven't found it yet... Any suggestions would be distinctly welcome... I'm hoping to get a linux box set up here today, and maybe tracing through the same process under linux will indicate the problem. Thanks! Warren

Re: Introduction and Sparc Solaris Status
by Warren_Baird＠cimmetry.com 25 Mar '02

25 Mar '02

> On Sparc processor? you mean you're emulating all the other layers too? like > processor, ram, video etc? isn't it kinda ... slow? Note that I said "winelib", and not "wine". Winelib only allows you to *recompile* win32 apps on *nix platforms. So I can take win32 source code, and compile and run it on solaris, hence no emulation is required... > Have you managed to run something a bit more complicated then notepad? again - > I (and I'm sure others) will be happy to hear about this stuff... Not yet. I've built the winemine, notepad and clock sample programs so far... My intent is to try to get the cursor issue fixed, and then worry about porting the rest of our code... Warren

OT: Buggy fonts
by Russell Howe 25 Mar '02

25 Mar '02

I'm afraid this is a little off-topic, but every time Wine starts, as it builds the font metrics, xfs-xtt (the font server) dies. I'm assuming there's a font (or few) in the system which it doesn't like, or which are corrupt. It makes wine rather annoying to use (and means that if I kill wine and restart the font server, it thinks the metrics are already done and ignores most of my fonts!) Does anyone know an easy way to find out which fonts they are? -- Russell Howe rhowe(a)wiss.co.uk

Adding new libraries to the repository
by Shachar Shemesh 25 Mar '02

25 Mar '02

Hi list, Like I mentioned ealier last week, I intend to add BiDi support to WINE. There is a library called fribidi (http://fribidi.sourceforge.net/) that does a pretty good job, and seems exactly apropriate for this task. I have two questions: A. What are my chances of getting a patch of this magnitude incorporated into the tree. The library is not particularily big, but includes a set of unicode translation files that are automatically generated from the unicode standard. It seems that WINE holds similar files itself, for similar purposes. I have not yet checked whether they conflict, and if they do, whether this conflict is resolvable. B. The library is under the LGPL license. I understand that some of the WINE tree is under the same license, while other parts are under the X11 license. Can someone please comment on the implications of such a move? What things do I need to take into consideration? I would also like to solicit the help of any Arabic speaking developer in this process. I know some of the basic concepts behind Arabic writing, but I am not nearly fluent enough to provide bug free code. Shachar

DDE Problems again
by Sylvain Petreolle 25 Mar '02

25 Mar '02

Hi, I'm currently running Netscape 6.01 with wine. Runs very fine for me, thanks to you and others.... (I'm writing this mail with it :) ) I only have a problme with ddeml. I got a message at start of netscape 'DDE done with INITIATE but no server window available' that causes a plug-in not to start correctly. What could help with this ? Is there a tip to open a server window before launching netscape ? Thanks by advance, Sylvain. ___________________________________________________________ Do You Yahoo!? -- Une adresse @yahoo.fr gratuite et en français ! Yahoo! Mail : http://fr.mail.yahoo.com

First regression test (alloc.c) - Please give feedback
by Geoffrey Hausheer 25 Mar '02

25 Mar '02

Okay, here is my first shot at writing a regression test (in this case for memory management routines. Before I go and write any more tests, please let me know any issues with style, or if it is just plain wrong. I've tested on Wine and Win2k, one test is marked TODO, and two functions aren't implemented in Wine (LocalDiscard and GlobalDiscard which are macros in VC++ winbase.h), so I have disabled those checks. There are likely still bugs in this too (though I've done my best to find and remove them), so please pointout anything like that as well. If all is well, feel free to commit this (or I can resubmit it to wine-patches) Also, I'll distribute this and all other regression tests I write under the X11 license, so everyone can use it.

Bug 519
by Shachar Shemesh 24 Mar '02

24 Mar '02

http://bugs.codeweavers.com/show_bug.cgi?id=519 Unicode defines a character known as BOM, that identifies a file as a UNICODE encoded file. Though this file should probably not be printed, if sent as the first char to DrawText or ExtTextOut windows ignores it. Wine doesn't. I'll probably post a fix to that as part of the other stuff.

Some problems building winsock.so
by Lionel Ulmer 24 Mar '02

24 Mar '02

Hi all, Seems that there is an include missing now in the 'socket.c' file in dlls/winsock as it does not find the definition of 'struct timeval'. I fixed it by adding in my tree a #include <sys/time.h> but I wonder if this is the right 'portable' way to do it (otherwise, why would autoconf check for time.h and sys/time.h problems :-) ). Did not see from what patch the problem occured. Lionel -- Lionel Ulmer - http://www.bbrox.org/

DOSFS_GetFullPathName
by Enrico Horn 24 Mar '02

24 Mar '02

Hi, Ive been trying to get Heroes III to work with wine and I found that it cant load some file it needs because DOSFS_GetFullPathName return the path to that file without the backslash at the end although heroes3 asked for it with a backslash at the end. it asks for .\\DATA\\ and the method returns <path to heroes3>\DATA <---- missing backslash in the method the last backlash is removed when no driveletter is in the requested pathname. I'd like to know why this was implemented like this as I cannot understand the reason for it. Thanks for your help Enrico farmboy1(a)subdimension.com

Hello All, I recently made a post asking for help and possible examples of how to use native Linux libraries from Wine applications but I am not sure if my emailer sent it off correctly. Could someone please tell me more about how I can access native linux libraries from my wine and my applications running under?

Even more dumb regression questions...
by Geoffrey Hausheer 24 Mar '02

24 Mar '02

InitiallyI thought I'd start with writing a test in Perl, and I got some basic stuff working. But then I needed to access structures, constants, etc, and had no idea how to do this, so I am now rewriting my test in C. My understanding was that for the most part, the C and Perl testing infrastructure were supposed to be comparable, but I haven't seen any examples of how I can do the things I mentioined (specifically, access constants (flags for functions), or create/read structures required by functions. Is this possible to do, and if so could someone give me an example of each? The constants are obviously less difficult, in that I could always redefine them in the test, but being able to manipulate structures seems like it would be a requirement for the framework. Sorry if this is all really straight forward. Thanks, .Geoff ----------------------------------------------------- Protect yourself from spam, use http://sneakemail.com

Window focus regression
by Duane Clark 23 Mar '02

23 Mar '02

This patch to windows/x11drv, back on Feb 25, causes a window focus regression. It has been reported on wine-users, and also affects my apps. http://cvs.winehq.com/patch.py?id=1014666451571945191826671 What a coincidence, this was submitted by Dave :-) Since I don't understand what this was attempting to fix, how about a trade. I will fix the toolbar bug I introduced, and could you take another look at this one? Basically, I am running Gnome (RH 7.2) and have the window manager mouse focus set to follow the mouse. When I slide the mouse out of and back into a managed wine window, the window does not completely regain focus. The mouse focus is returned, but not the keyboard focus. This can be seen in SignLab. I select the text tool, click somewhere in the window, type a few characters, then slide the mouse out of and back into the window. Now typing has no effect until I click the mouse somewhere in the window. Clicking somewhere in the grey border area allows the keyboard focus to return without cancelling the text tool.

Well, the .def file that winebuild generates have references to stubs that are implemented in the .spec.c. This could of course be fixed by a simple if statement somewhere, I guess. However I'm not sure that there aren't other things that might be needeed so I generated and compiled .spec.c just in case. > All you should > need is a .def file, In any case the first part of the patch (winebuild.diff) is needed even to generate the .def file so please apply that regardless. > and maybe a small hack for the debug channels > declarations. Yes. But that could just as well be done in .spec.c like on Unix couldn't it? However I understand if you think winebuild2.diff is a little hacky. I'm not 100% satisfied with it myself. So what do you suggest? Is the debug channels really the only problem?

More dumb regression questions
by Geoffrey Hausheer 23 Mar '02

23 Mar '02

How do I run a wine perl regression test in Windows? I thought the entire point was to make it so you don't need a c-compiler, yet I can't seem to get the tests to run without the winetest application (which I've been unable to build on windows so far). Is it planned that this executable be distributed with wine, or am I missing something else? Ideally, I'd like to be able to get just the tests and required apps through cvs (or even a .zip file), and run them. If this is possible today, it isn't obvious (to me) how to do it. Sorry if this is documented somewhere, but I checked Francois' presentation, and the huge thread in January, and didn't find anything about it. If you want to convince people to help write tests, it'd sure be nice if it was easy to find information about how to do it :) .Geoff ----------------------------------------------------- Protect yourself from spam, use http://sneakemail.com
