If it were all in the server (including actual read and write calls) it might be simpler... but probably not efficient, like you say. i think most of the data transferred from a serial port is pretty small though... but if the scheme was expanded to handle overlapped socket operations that wouldn't be true. Additionally, i though it might be useful to have a way to write small chunks of data to the client's memory. For example, when implementing WaitForNamedPipe and ConnectNamedPipe, i need to write a result code into an overlapped structure... it's only 4 bytes, but i need to create a new type of APC to deal with it. If i had a method to write directly into client memory, it would be simpler.

Hi Alexandre, Hmmm. i'm not exactly sure about this. i don't think the server ever blocked on serial port reads or opens... i think the reason Lawson had problems was that the client thread was blocking in the overlapped read code. (FILE_AsyncReadService in files/file.c) If we use non-blocking fds unconditionally, a non overlapped ReadFile may result in a busy loop in the client thread. Additionally, overlapped read (and write) requests should fail unless the handle is opened with FILE_FLAG_OVERLAPPED. There are programs that depend on that behaviour (as reported by Eric Kohl, 3 Feb 2001 on this list). This is another reason to propagate CreateFile's attributes parameter into the wineserver. Another question: do you think it would be possible to implement a "write memory" message from the wineserver to the client? This message would be carried over wait_fd and would be received by the client asynchronously in wait_reply(). The message would contain a length, address and data to be written. If this is possible, i could move async i/o back into the server, keep it efficient and perhaps implement CancelIo properly...

Daniel Walker <diwalker(a)earthlink.net> writes: > How is it unreliable? Why is MSG_PEEK more reliable? I'm not opposed to > using MSG_PEEK , just curios.. FIONREAD is unreliable because you cannot distinguish between an EOF condition and an empty receive buffer. recvmsg(MSG_PEEK) is supposed to return 0 on EOF, and EWOULDBLOCK on empty buffer, so you can determine the real status. > Another issue is why doesn't poll() give > us a POLLHUP?

As I understand it poll() returns POLLHUP only when both directions of the socket have been closed; but if you shutdown() only the read or write side, you don't get POLLHUP so that you can continue using poll() for the other direction. This has apparently been changed between kernels 2.2 and 2.4; in 2.2 POLLHUP is returned as soon as the read side of the socket has been closed. -- Alexandre Julliard julliard(a)winehq.com

But FIONREAD can return 0 bytes even when the socket isn't closed (for instance if another thread got the data first). You can only determine that it was really closed when you do the actual read. So I don't really see how we can avoid having recv() return zero; well maybe we can make it return EWOULDBLOCK and tell the server the connection is closed, but I'm not sure it's any better. -- Alexandre Julliard julliard(a)winehq.com

-clocal and the wineserver
by lawson_whitney＠juno.com 19 Aug '01

19 Aug '01

Good day! Any time clocal falls out of the modem's termios (say I use cu -l on it) the wineserver hangs trying to open it, or at least the app hangs, and I haven't found a way to kill it without killing the wineserver. Both 16 and 32 bit versions of juno are affected. I haven't really investigated it very thouroughly, but I wasted a lot of time restoring backup versions of the app and wine. Should I look into mickey-mousing the open to avoid the problem, or - is it really a wineserver problem which I am probably not even marginally competent to muck with? I'd be glad to make traces or winedbg output, but it seems the problem should be easy to duplicate. Hmmm, setting clocal back on from another terminal unhangs the app. That is neater than killing the wineserver, I guess. terminal.exe from wfw 3.11 behaves similarly, with an extra twist: it hangs on the Win16Mutex until somebody sets clocal (well, I guess carrier detect would work, too).

For standard controls like buttons it should never be a problem since there is both an ASCII and Unicode win proc, so in a pure ASCII app we should never do the conversion.

The Api returns number of chars, not bytes. The idea is that 6 Unicode chars can yield more than 6 ASCII chars with DBCS text.

Re:CryptoAPI
by Eric Pouech 18 Aug '01

18 Aug '01

from a pure technical point of view, the crypto API is in a pure WOSA style : - a set of high level API (in advapi) - an extendable set of low level service providers (here for example the crypto algos - RSA....) - the high level maps the fonctional request of the user onto on of the available SP. so, my advice here would be to implement this type of scheme. This would allow to: - use native DLLs if they exist (and go beyond what's supported by Linux) - still allow to use Linux lib (just build a wrapper DLL to that lib) and you should be all set from a copyright point of view: - Wine use a X11 like licence, so make sure all the external libs you use are not GPL (LGPL is fine). If they are GPL, you won't be able to ship the result with Wine. - Use of native DLL is granted as long as you have a Windows licence on the target machine (native DLLs shall not be shipped with Wine, Wine should be configured to use the local resources) from an exportation point of view: - some countries (US as an example) puts lots of contraints on the type of crypto algo to be used outside of the US. So those shouldn't be shipped with Wine's, but be provided as an external resource) > Hi, > > I was going to start implementing the Cypto API (in advapi32.dll) over the > next few weeks.

dsound ??
by Bobby Bingham 17 Aug '01

17 Aug '01

Hello all, I completely rebuilt my computer a while back, and updated wine, so I'm not sure which is causing it, but not dsound doesn't seem to work where it did before. Starcraft doesn't play any music, sound, etc, but it's installer still plays it's sound (without dsound). Before this I hadn't updated WINE for a while, so I'm not sure when it broke. Bobby Bingham

The >non-client area should be painted upon WM_NCPAINT, not WM_ERASEBKGND. How do you test this under Windows ? In my test app, I have a white brush as class brush. So my window is white. If I add after the BeginPaint : GetClientRect(hwnd, &r); r.top += 200; FillRect(ps.hdc, &r, (HBRUSH) COLOR_WINDOW) the lower part of my window is painted with the beautiful window color (brown) Now if I add immediately after : hdc = GetWindowDC(hwnd); SendMessage(hwnd, WM_ERASEBKGND, (WPARAM) hdc, 0); ReleaseDC(hwnd, hdc); I get a window that is completely white; maybe I am missing something but I should see a small brown strip at the lower part of the window, corresponding to the caption + menu height, no ?
