socket question
by michael cardenas 25 Mar '02

25 Mar '02

I'd like to throw this out there for anyone more familiar with sockets in wine than I am. Here's some of the output of running aol with --debugmsg +winsock: trace:winsock:WS_socket af=2 type=1 protocol=0 trace:winsock:WS_socket created 0320 trace:winsock:WS_bind socket 0320, ptr 0x40595b7c, length 16 trace:winsock:WSAAsyncSelect 0320, hWnd 006f, uMsg 00000468, event 00000033 trace:winsock:WSAEventSelect 00000320, hEvent 00000328, event 01000033 trace:winsock:WS_connect socket 0320, ptr 0x40595b50, length 16 trace:winsock:WINSOCK_DoAsyncEvent socket 00000320, event 00000328 trace:winsock:WINSOCK_DoAsyncEvent post: event bit 4, error 10061 trace:winsock:WINSOCK_DoAsyncEvent socket 00000320, event 00000328 trace:winsock:WINSOCK_DoAsyncEvent post: event bit 5, error 0 trace:winsock:WSAAsyncSelect 0320, hWnd 006f, uMsg 00000468, event 00000000 trace:winsock:WSAEventSelect 00000320, hEvent 00000000, event 00000000 trace:winsock:WINSOCK_DoAsyncEvent socket 00000320, event 00000328 trace:winsock:WINSOCK_DoAsyncEvent orphaned event, self-destructing this seems to happen over and over again. My application sets up it's socket to send it a window message when the event happens, but the event takes too long and so the app turns off the notification, and the event becomes orphaned.

Re: debugging longman dictionary
by Laurent Pinchart 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

> 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
