dlls/advapi32/crypt.c
by Morten Welinder 13 Sep '01

13 Sep '01

Someone added code to CryptGenRandom so that it generates very bad random data (with <10 bits randomness in them). Don't do that. It's a known security risk. Read from /dev/urandom instead. If that does not succeed, just abort(). Linux and newer Solaris have /dev/urandom. I would guess the BSDs have it too. Morten

wcs* functions within Wine
by Huw D M Davies 13 Sep '01

13 Sep '01

Hi, I want to use wcsrchr and wcstrol in oleaut32.dll . If I just use them then we do indeed call the ntdll versions rather than libc which is all very nice. The question is, what include file am I supposed to use to get their protoypes? Huw.

unmanaged windows
by Bobby Bingham 13 Sep '01

13 Sep '01

I think there was a discussion a while back about possibly rewriting the "unmanaged" mode (or adding a new mode, I don't recall which) to make it more like XMMS, but I can't find it now. This would really help on my system, as with KDE 2.2, wine windows are always on top and on every desktop and XMMS fits in a little better. I was wondering what the result if any, of that discussion was. Bobby Bingham -- Microsoft Windows: Made for the internet The Internet: Made for UNIX

winedump prints a strange export table
by Francois Gouget 13 Sep '01

13 Sep '01

If I run 'winedump dump ws2_32.dll -j export' I get a strange result: ... 00000000 125 <by ordinal> 00000000 126 <by ordinal> 00000000 127 <by ordinal> 00000000 128 <by ordinal> ... Are these really significant? It seems like they go all the way up to the highest ordinal of a 'real' exported function, here 500, WEP. Also if I run 'winedump dump msvcrt.dll -j export -C' winedump seems to crash. It looks like it tries to interpret mangled names as glibc mangled names? Hmm, '-C' seems to have trouble even with other dlls. Christian Jiresjö expressed interest in working on winedump (see bug #91), maybe these would be good bugs for him to takle.

HAVE_IPX cleanup
by Francois Gouget 12 Sep '01

12 Sep '01

This patch attempts to clean up the ws_sockaddr_ipx to sockaddr_ipx conversions (and vice versa). I would really like if people could try this out: I don't have a working IPX network here. At least my very rudimentary tests indicate that this should still work for the TCP/IP case. More details on the patch: * all ws_sockaddr structures must be considered to have a potentially different layout from their Unix counterparts. Sure for now we just borrow the Unix structs anyway but even sockaddr_in does not have the exact same fields on FreeBSD and Linux (although the binary layout is the same). And hopefully we will not borrow the Unix structs for long anyway. FreeBSD testing is another aspect I would appreciate help with (sin_len worries me). * the ws_sockaddr_ipx fields did not match those used by windows. Also ws_sockaddr_ipx was declared in the wrong header. * all conversions are now done in two functions: ws_sockaddr_ws2u and ws_sockaddr_u2ws. If there is a conversion to do then these are the only two places that should be affected. SUPPORTED_PF returns whether a given protocol family is supported or not. * the sockaddr* pointers may point to structures that are more than 16 bytes, typically 28 bytes for IP v6. I tried to take this into account, I hope I did not mess up (but I'm not sure Wine would support TCP/IP v6 anyway). * I modified WSOCK32_accept to call WSOCK32_getpeername thus avoiding the conversion issue entirely in WSOCK32_accept. * all other functions that were doing such conversions were modified to use the above functions. I also tried to make the error handling code more consistent wrt. WSAENOTSOCK, WSAEAFNOSUPPORT, etc. * removed ugly casts in the traces -- Francois Gouget fgouget(a)free.fr http://fgouget.free.fr/ "Utilisateur" (nom commun) : Mot utilisé par les informaticiens en lieu et place d'"idiot".

Russian keyboard layout
by Andriy Palamarchuk 12 Sep '01

12 Sep '01

Hello everybody, I want to fix message about not found keyboard layout for my configuration. The FIXME message is not shown after I add a phantom key definition to russian keyboard layout main_key_RU in file windows/x11drv/keyboard.c I need your advise how to do it correctly. Should I change existing layout - main_key_RU or it is better to add a separate one with phantom key - main_key_RU_phantom, like it is presently done for US layouts? I could not suppress the FIXME message by changing keyboard model in XF86Config from "pc102" to "pc101". My system: Wine release 20010824, installed without Windows, gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-81) The layout, defined in XF86Config is "ru(winkeys)". Thank you, Andriy Palamarchuk

Solaris winsock support
by Robert Lunnon 12 Sep '01

12 Sep '01

Trying Eudora 4.3 on Solaris solicits this error err:winsock:WsControl Unable to open /proc filesystem to determine number of network interfaces! Looking about in the code WsControl grubs about in the /proc filesystem to get the names of, and count the number of network interfaces. Since /Proc only hosts processes on Solaris this constitutes a linux dependancy we don't need. Studying the ifconfig source gives another possibility instead which look like it may be more portable using ioctl SIOCGIFCONF on an arbitrary IP socket The return from this call is a structure containing the length of the reply buffer, which seems to contains an array of ifreq structures (one for each interface) which contains among other things the name of the interface. By dividing the size of the buffer by the size of the returned objects we know how many interfaces there are... Questions Anyone know if this is Is this workable ? Is this workable on linux, (I ask because I don't have linux and don't know linux ioctl implementation details)?

Re: Dialog painting

> Wine currently seems to have a problem painting splash dialogs properly > (or at all). I took a closer look at this. I just ripped out the interesting parts from Speak freely in order to find a simple program exhibiting the problems. What I ended up with was a program which does nothing interesting except to show a simple dialg using CreateDialog(). It still doesn't work under Wine. The source is attached. I'm somewhat at a loss about what to do now. I'm just not clear about what should happen and why it doesn't. Some browsing around in the source suggests that it may related to the focus problems Gerard has been talking about, but I'm far from sure. Any comments?

Even though SetForegroundWindow >does nothing if its parameter matches current foreground window, >it can be easily seen that having more than one window can lead >into livelock. I think that the problem with focus is that when a window is shown by Wine, synthetic WM_GETFOCUS and WM_SETFOCUS events are generated, that are themselves generating X focus events. The X events are kept in the X queue until Wine finds time to handle them. Wine creates window A : WM_GETFOCUS for A Wine creates window B : WM_KILLFOCUS for A, WM_GETFOCUS for B Wine creates window C : WM_KILLFOCUS for B, WM_GETFOCUS for C Now, when after all this the X events are processed, Wine handles a X focusin event for A, that is generating a WM_GETFOCUS, then a focusout for A, generating other WM_KILLFOCUS and WM_ GETFOCUS, focusin for B, etc..; the sequence of events when creating windows is perfect, but there are extra events after. IMO what's wrong is that X focus events are not ignored when they are the following of program action. The following hack disables focus handling in this case. I have no clue on its value since I am currently struggling with other bugs. and I will not come to these problems until some time - maybe a lot of time if current Wine progress (aka regressions :-)) continues. --- event.c.orig Fri Aug 24 09:30:46 2001 +++ event.c Mon Sep 10 13:00:28 2001 @@ -534,6 +534,8 @@ if (!hWnd) return; + if (!event->send_event) return; + bIsDisabled = GetWindowLongA( hWnd, GWL_STYLE ) & WS_DISABLED; /* If the window has been disabled and we are in managed mode, HTH Gerard

Maybe the problem is that it succeeds. However, Win32s is present in Wine since years and has not been touched since a long time. I think unlikely that it could be a new problem - when was the last working Wine version before current Cvs ?

There is no hwnd type in the spec files, AFAICT. That's not a matter of typing GetWindow(hwnd word) instead of GetWindow(word word) - I think it is necessary to actually change winebuild to define a new type and write a bunch of code to support it. I have looked at the points where it current cvs crashes and it's necessary to fix 16 to 32 bits handles and I have found that 2 changes cure all my new crashes : the one in DestroyWindow16 and another in DefWindowProc16 The reason for these problems is the same : Wine is keeping window handles in several variables (active window, focus window) and Wine code does several comparisons between applications provided handles and these values. In the last case for example, the test /* activate hwndTop if needed. */ if (hwndTop != GetActiveWindow()) { in focus.c fails because of the high word part (and creates an infinite focus loop) I'd say that by adding also handle fixes in SetWindowPos16, SetFocus16 and SetActiveWindow16 as well as fixing the handles setters in queue.c, everything would be covered. IMO your solution is 1) somewhat complex for a fix to apps not widely used anymore 2) overkill because it's not necessary to convert window handles for each and every Api. OTOH your solution is more elegant. I don't know what to do. Gerard

Dialog painting
by Niclas Karlsson MATE 10 Sep '01

10 Sep '01

Hello! Wine currently seems to have a problem painting splash dialogs properly (or at all). Is this a known problem (with a known cause)? An open source program exhibiting problems of this kind would be Speak Freely (http://www.fourmilab.ch/speakfree/windows/). I will try to single out the cause of the problem when I get a little spare time, unless the cause is already known that is. Also, I haven't used Wine for some time so I don't know if this is a long-standing problem. The version I used was a cvs snapshot from last friday before the commits.

what if MS is forced to publish all API's?
by Scott Bradford 09 Sep '01

09 Sep '01

with all the discussion going on in the press about what to do with Microsoft to remove their Monopoly power or at least see to it that they don't abuse their power, how to folks here feel about forcing them to release all their API's? I'm not a programmer myself, but it's my understanding that not having access to the API's is what makes wine such a challenge. If this is the case, would getting access to the MS API's allow Wine to be completed? I feel that a MS breakup wouldn't have done much to change things because they can still give information only to whom they choose, leaving MS to decide who can play and who can't. Having other ways to run the application base of windows software would remove the need to run windows itself, and in my mind, this is the easiest way to remove monopoly power of MS. What do you folks, the Wine developers, think should be done to MS?

Focus livelock
by Jukka Heinonen 09 Sep '01

09 Sep '01

I posted a patch that would fix a focus related livelock. However, I have to admit that the patch is quite hacky and likely not to be included in Wine. Since I would like to get this bug fixed, I thought to ask opinions about the correct way to fix the bug. The short description of the bug is that setting active/foreground/focus window in Wine calls X11DRV_SetFocus, which calls XSetInputFocus. This makes Wine receive FocusIn event, the handler of which calls SetForegroundWindow. Even though SetForegroundWindow does nothing if its parameter matches current foreground window, it can be easily seen that having more than one window can lead into livelock. This happens repeatably every time you start Colonization for Windows. I'm currently thinking about calling directly some WINPOS_* routine from X11 FocusIn handler instead of SetForegroundWindow. If the routine acted exactly like SetForegroundWindow except it made sure that it causes no calls to X11DRV_SetFocus, focus problem would be fixed. Unfortunately I have not figured any good way to pass an extra flag to default handler for WM_ACTIVATE, so that the routine would call something like SetFocus_DontCallDriver instead of regular SetFocus... -- Jukka Heinonen <http://www.iki.fi/jhei/>

WM_[LR]BUTTON{DOWN,DBLCLK} in menus
by Bobby Bingham 08 Sep '01

08 Sep '01

I was writing a stupid app to help my friend learn to use menus in windows apps. It would call TrackPopupMenu on a WM_LBUTTONDOWN message. After some experimentation, I found that if I leftclicked in the client are, the menu would appear, as it should. But if, while the menu was still active, I leftclicked in the window's nonclient area (titlebar), the menu would appear elsewhere. By clicking the menu receives a WM_LBUTTONDOWN message, and determines that it should close the menu as it's not inside the menu, and it doesn't remove the message. This is normally fine, but if the click falls on the nonclient area of a window, the message should not be passed through. I believe this also applies to WM_LBUTTONDBLCLK, and the right button equivalents. Is there an easy way to determine what window the click would be passed through to, so we can check if it'll be in the client area or not?

It would be nice if all APIs that return strings behaved the same way, but unfortunately this is not the case: some count the terminating null, some don't, some copy partial strings when the buffer is too small, some don't copy anything, etc. We would need about as many helpers as there are API functions.
