I am not trying to _load_ a Windows driver (that either requires kernel support for the Windows DDK, like ndiswrapper has, or emulation of an entire x86, like bochs does). What I am trying to do is _replace_ a Windows driver with equivalent libusb functionality, getting, in effect, something like this: Application (eg. the Gimp) | v special SANE backend | v SANE to TWAIN converter | v Windows user-space TWAIN driver (by manufacturer) | v STI | v Wine (with "drivers") | v Wine (user-space) driver | v libusb | v kernel > Mike Damjan __________________________________ Do you Yahoo!?

[riched20/list.c] Exception in ME_DumpDocument
by Paul Vriens April 4, 2005

April 4, 2005

Hi, After I found that one of the files still contained a debugchannel for riched20 (instead of richedit), I added both to see a trace (just for the fun of it). This however raised an exception in ME_DumpDocument: trace:riched20:ME_DumpDocument Start Paragraph(ofs=0) - StartRow - A-LOT-OF-TEXT Paragraph(ofs=266) - StartRow - A-LOT-OF-TEXT Paragraph(ofs=316) - StartRow - Run("L"\00b6"", 0) wine_dbg_vprintf: debugstr buffer overflow (contents: 'A-LOT-OF-TEXT') First chance exception: assertion failed in 32-bit code (0x001117a2). backtrace: Wine-dbg>bt Backtrace: =>1 0x001117a2 (0x00809b30) 2 0x0027d882 (0x00809c5c) 3 0x00157023 NTDLL_dbg_vprintf(format=0x112f5c48, args=0x809cd8) [/data/install/linux/wine-src/wine/dlls/ntdll/debugtools.c:267] in ntdll (0x00809c84) 4 0x001570c8 NTDLL_dbg_vlog+0x44(cls=0x3, channel=0x112ff48c, function=0x112f5c38, format=0x112f5c48, args=0x809cd8) [/data/install/linux/wine-src/wine/dlls/ntdll/debugtools.c:303] in ntdll (0x00809ca0) 5 0x0023f880 wine_dbg_log+0x28(cls=0x3, channel=0x112ff48c, func=0x112f5c38, format=0x112f5c48) [/data/install/linux/wine-src/wine/libs/wine/debug.c:234] in libwine.so.1 (0x00809cc0) 6 0x112ebca6 ME_DumpDocument(buffer=0x7f370510) [list.c:174] in riched20 (0x00809ce8) Questions: - Could the exception be because of the length of the TRACE string? - Is there a particular reason for the 'different' debugchannel? - Is ME_DumpDocument used just for debugging?

WineConf Agenda
by Brian Vincent April 4, 2005

April 4, 2005

I'm going to start this off with a huge apology - there's a very real chance I've asked someone to do a presentation and it's not on this list. If so, you need to email me to remind me. If you were definitely planning on presenting something because I emailed you, let me know - there's lots of space available. I know this only affects 2 or 3 people, but I tossed around a few ideas and didn't want to leave any loose ends. (Any of those items would make nice topics.) This is the initial agenda for WineConf. I hope to add a few more items, but Jeremy suggested I pull the trigger and announce it. I agree - there's enough here to fill two days and leave a lot of time for people to get together in small groups. Only the first two items are in any formal order: Alexandre - Keynote (He said he's reusing last year's slides.) Dimi - to do list / status update Steven Edwards and the ReactOS crew Charles W Stevenson - Winelib / Winelib porting / and a commercial perspective Andrew Barlett / Samba team? - Samba 4, authentication, lots of intelligent ideas Juan Lang - Wine's RPC + Samba or something like that :) Jeremy White - CXTest Jason Edmeades - DirectX 9 / wined3d / eye candy I think a full agenda would be about 11 items. If you would like to present something let me know - there's definitely space available. If you've been wondering, "There's a neat project I'd like to do if I could only get a few more people interested", well, this is the perfect time to bring it up. If there's something strategic to Wine development, this is a great time to discuss it. For example, we've had mixed feelings regarding revision control and its been suggested to bring it up as a topic. Would anyone find it useful to discuss subversion vs. arch vs. cvs? We could probably get Mike Hearn to show off how he manages patches with SVK and then let him arm wrestle Alexandre about whether arch is better. Friday night we will have an informal dinner after meeting up at the hotel. The conference will kick off Saturday morning on campus around 8am. Lunch will be provided on Saturday and Sunday as well as dinner on Saturday. There will definitely be a lot of time for informal discussion. For the Samba guys - I think there's a great opportunity to share some knowledge to prevent anyone from reinventing the wheel. If there's any topic you'd find interesting, let me know. If you'd just like to hear a specific topic from the Wine folks, we can arrange that. For travel arrangements, please join wineconf(a)winehq.org ( http://www.winehq.org/mailman/listinfo/wineconf ) For instance, I'm actually flying into Frankfurt on April 23rd and it'd be cool to hang out with anyone arriving early. If you haven't made reservations at a hotel, don't worry too much. There's still rooms available as Mr. Schmid described here: http://www.winehq.com/hypermail/wine-devel/2005/03/1119.html If you haven't signed up on the RSVP list, please do so. It can be found on the WineConf page: http://www.winehq.com/site/wineconf Lastly, if you have any questions / comments / criticisms let me know. -Brian PS. Dimi owes me a beer from last year, so we're all obligated to go out Friday night. I'm looking forward to seeing everyone in Stuttgart!

Wine device drivers proposal
by Damjan Jovanovic April 4, 2005

April 4, 2005

Hi I've been trying to add STI (still image) support to Wine, and I've made some progress. However, I see a deep and unsurmountable need to add (at least user-space) device drivers to Wine, and I would like some feedback on these ideas. Basically, many Windows device drivers are really trivial, but required for many apps. A scanner driver typically just accepts commands from a user-space app, does minimal processing, and forwards that to Windows. I've already hacked up Wine to get the same functionality, and it works - partially. I propose adding a driver loading system to Wine that works as follows: -CreateFile() gets a device filename, like (in my case) \\.\MiiScan0 -Currently, Wine's behaviour for such a filename is to try load a VXD. -In the case of VXD loading failure, a search is performed in (Wine's) C:\Windows\System32\Drivers (or somewhere else?) for a matching driver. The driver is then loaded and used for (at least): ReadFile() WriteFile() DeviceIoControl() CloseHandle() The problem is, how is a handle mapped to the appropriate driver? I've thought about it, and come up with 3 solutions. The first 3 don't require changes to the wineserver but aren't pretty. 1. Make the driver a true Linux kernel mode driver, and the handle its device file handle. Since ReadFile() and WriteFile() just do read() and write() system calls, this can be done. The problem is, DeviceIoControl() has to be implemented using ioctl(), and that's dangerous (sending the right codes to the wrong device can be catastrophic). Also, it's not portable to other OS's, and requires writing a kernel module (which isn't fun). 2. The driver is a file giving a process to start and some IPC method to use. Wine starts the process and uses the IPC method to communicate with the driver. This is good as far as Wine's current ReadFile() and WriteFile() go, since they don't have to know they're not writing to an actual file. The problem here is, which IPC method supports both read() and write() on the same file descriptor, preserves message boundaries, and carries out-of-band data for DeviceIoControl()? I was thinking TCP sockets, but they don't preserve message boundaries. 3. KERNEL32.DLL and / or NTDLL.DLL keep their own handle table so they know which handles are driver handles and deal with those appropriately. Having to look up these tables for every call to ReadFile(), WriteFile() and DeviceIoControl() might be very inefficient, though. 4. Use an in-process solution, like a winelib DLL that has exports for dealing with ReadFile(), WriteFile() and DeviceIoControl(). This could be the most efficient, but then again, you need an efficient way to test a handle for being a driver handle, find the appropriate driver, and call the right exported function, which likely means the wineserver needs to have knowledge of these drivers and provide functionality for testing a handle for being a driver handle and have a way to find the driver. Let me know what you think. Bye Damjan __________________________________ Do you Yahoo!? Yahoo! Small Business - Try our new resources site! http://smallbusiness.yahoo.com/resources/

Riched20: thanks + regression "beta" not shown
by Tobias Burnus April 3, 2005

April 3, 2005

Hello, first I'd really like to thank the riched20 workers, notably Krzysztof Foltman and Phil Krylov. For the application Diamond it made a big difference: Instead of "[[Aring]]" etc. one sees the proper symbol and it looks much nicer. But the biggest advantage is that one can now copy or save the text; before the app was simply crashing when attempting to do so. Regression: One of the later riched20 patches, possibly http://cvs.winehq.org/patch.py?id=16672, caused a regression with the richedit control in Diamond. Before it showed a beta character from the Symbol font, now it only shows a box ("[]"). If one saves the output (rtf export) one sees ------------------- {\rtf1\ansi\ansicpg1252\uc1\deff0\deflang1031\deflangfe1031{\fonttbl{\f0 Times New Roman;} {\f1\fcharset0 System;} {\f2\fcharset2 Symbol;} }{\*\generator Wine Riched20 2.0.????;}\pard\li0\fi0\ri0{\b\fs18\ul Bibliographic data} \par\pard\li0\fi0\ri0 [...] \par\pard\li0\fi0\ri0{\fs18 }{\i\fs18 b}{\fs18 = 5.8312(2) \'c5} \par\pard\li0\fi0\ri0{\fs18 }{\i\fs18 c}{\fs18 = 7.9564(2) \'c5} \par\pard\li0\fi0\ri0{\fs18 }{\fs18\f2 \u61538?}{\fs18 = 100.77(0) \u176?} ------------------- In the last line, after the \f2 (Symbol font), there should be a beta ("b" + Symbol font).

discusion about a message loop in listview.c
by Dietrich Teickner April 1, 2005

April 1, 2005

I have some weeks before reported, FlashFXP v3.02 loops with a message-loop in listview.c after login. It does this in Odin and in Wine. In Odin it stops in smaller time (deep 1000). Wine has a bigger stack, and so needs wine more time for this, bat I can see in the loog, the args for the function are more and more locatet at lower stack adresses. I have written this workarout for testing this problem in wine and in odin. with this FlashFXH 3.02 will display the contence of the server dir very fast at both environment. In the log I can see, that the message-loop was reported and stopped. I thing, we need a flag inside any item to report every function, that can called recursive, this item is in work (function-separart, or global ?), that can stop recursions of this type in the future or many programms. I have also found this try does also helps Agent 2.0 in the groups->defailt propertys (only odin-tested). This does also every crashs in earlyer builds with stack overflow in odin.
