There, we try to default to just searching the user's home directory when running on Wine, and I think we blacklist known do-not-search directories like /proc. We have gone back and forth about whether to follow symlinks; there are often symlinks to network filesystems inside people's home directories. The right thing to do is probably something like: a) get the set of initial seeds by using the output of the 'mount' command and ignoring anything with a type field that is not a known local filesystem type (e.g. ext2, ext3, ufs, reiserfs, xfs); you'll need to expand this whitelist as customers complain about their pet filesystems (And you'll need to ignore any that can't be mapped to Wine paths, but people usually map Z: to /.) (You could use /proc/mounts under Linux, but better to use the standardized 'mount' command or maybe /etc/mtab, otherwise your code will break on MacOSX or Solaris.) b) when recursing, and you find a reparse point aka symlink, check the filesystem type of the symlink destination before following it. You might need to get bug http://bugs.winehq.org/show_bug.cgi?id=12401 fixed before this works the windows way, but you could probably do something wine-specific now by converting each directory path you encounter into a unix path, then using a unix api to check whether it's a symbolic link. Bleah. Best way to do that is to patch wine, and then you're part way to fixing bug 12401 :-) c) beware: Wine's implementation of FindFirstChange/FindNextChange does not really work if you ask it to monitor two different names for the same directory.

Re: wined3d: Convert between A8R8G8B8 and X8R8G8B8

A D3D surface is being converted from A8R8G8B8 to X8R8G8B8 and wine warns that there is no conversion function, so I added it. In practise it doesn't matter because the RGB parts are still valid, so nothing should change unless any app uses the X8 bits = unused. Just fixed a warning and was the right skill level for my first wine patch. I'm working on one that does a little more real work now.

OT [ReactOS-related] Win32s API dosumentation
by Wesley Parish 30 Sep '08

30 Sep '08

Hi. I'm wondering about doing a quick-n-dirty Win32s re-implementation for ReactOS, following an email [last-year-this-year] discussion on the ReactOS dev list. Based on Wine, of course, and operating as Windows-on-Windows in the Microsoft OS of the same name. Does anyone know where to get copies of the Win32s documentation, such as it is?

Re: richedit: Fixed test failing on windows version with larger font sizes

Hi Dylan, @@ -402,6 +401,10 @@ static void test_EM_SCROLLCARET(void) "ff\n" "gg\n" "hh\n"; + HWND hwndRichEdit = CreateWindow(RICHEDIT_CLASS, NULL, + ES_MULTILINE|WS_POPUP|WS_HSCROLL|WS_VSCROLL|WS_VISIBLE, + 0, 0, 200, 80, NULL, NULL, hmoduleRichEdit, NULL); + ok(hwndRichEdit != NULL, "class: %s, error: %d\n", RICHEDIT_CLASS, (int) GetLastError()); It seems to me in this case that describing the relevant parameters to CreateWindow--I assume just height?--and why they're important to the test might help people not break the test in the future. --Juan

Free apps bundled with msvcp71?
by Dan Kegel 29 Sep '08

29 Sep '08

Adobe Contribute 4, released in Nov 2006 or so, had a nice online trial at http://trials.adobe.com/Applications/Contribute/Adobe_Contribute_4_Win/Adob… and still online, I think, at http://www.soft32.com/download/63-129953-1/Adobe_Contribute_4_Win.exe Starting it fails with err:module:import_dll Library MSVCP71.dll (which is needed by L"C:\\Program Files\\Adobe\\Contribute 4\\CoreTypes.dll") not found Wine has a nice implementation of msvcr71.dll, but not the C++-oriented msvcp71.dll, nor is it likely to get one soon. This brings back the question: what's a good place to legally and freely download an application bundled with a full set of msvcp71.dll et al? Ideally something at Microsoft.com and/or something small and suitable for use in winetricks. Any ideas? - Dan

Ignore this; patchwatcher probably got confused by the word difference at the beginning of a line. This is a known and very lame bug...

All the cool kids at Wineconf are busily fixing "make test" failures. If you're not at Wineconf, you can still play along! See http://wiki.winehq.org/BugSquishParty for details and how to claim a bug to fix.

DIB engine status
by Huw Davies 29 Sep '08

29 Sep '08

Hi folks, Here's an update on the DIB engine that I've been working on for the last few months. This work has been made possible by the generosity of Google - so thanks go to them and of course to Dan. You can find the code at http://repo.or.cz/w/wine/dibeng-hd.git What's supported ================ - All dib section depths (including BI_BITFIELD support). - Single pixel solid and dashed pens. - The 16 rop2s. - Solid and dib pattern brushes. - A brunch of primitives for drawing onto all dib section surfaces. - GDI32 apis: LineTo, Rectangle and PatBlt. - An extensive test suite for all of the above. What needs to be done ===================== - Blitting (eg BitBlt, StretchBlt and StretchDIBits) - I have some hacks for these in my tree. - ExtTextOut - Many more GDI32 apis - a lot of these should be easy given that we have a set of underlying dib drawing primitives. - Non-MM_TEXT mapping modes and world transforms. - The initial interaction with GDI32 in BITMAP_SelectObject is hacky and needs some work. - Lots more... Note that at the moment it's essentially useless because of the lack of blitting, so unless you fancy hacking on that yourself then you probably don't want to bother fetching the tree. I'm going to stop working on this for a while (lots of fun Outlook 2007 bugs for me to look at!), but will endeavour to keep the tree up to date with respect to WineHQ. If someone *does* want to hack on this then feel free to send me patches! Thanks, Huw. -- Huw Davies huw(a)codeweavers.com

Wineconf-er caught at security.

I was stopped at security for carrying 'a wine bottle' through security. Upon a brief inspection it was revealed that my super-awesome crossover t-shirts had tripped the machine due to their lusciously exquisite compressed shape. Whoops. --Zach
