include: Include local not system sql.h header
by Andrew Talbot 12 May '07

12 May '07

I have just sent in a patch to use Wine's sql.h instead of the system one, because I noticed that the latter includes <sqltypes.h>, which appears to redefine DWORD as unsigned long, based on its reckoning that the size of a long integer is four bytes on default platforms, whereas - with _MSC_VER undefined - DWORD is an unsigned int. However, I now see that Wine's sql.h includes sqltypes.h, too. So my patch may be unnecessary or wrong, but should odbcinst.h preceed its inclusion of sql.h with some sort of definition of SIZEOF_LONG to prevent this redefinition? Please advise. Thanks, -- Andy.

Use system("/usr/bin/xdg-screensaver lock") or CreateProcess(). Ciao, Marcus

Fast events
by Maarten Lankhorst 12 May '07

12 May '07

Hi all, Since I'm trying to improve on winmm's timing scheduling, the best improvement I can find is getting rid of the wineserver calls, they add a huge delay to the timer and that is bad for something that should sleep all the time to get better scheduling. I tried sending in a patch that used linux sockets but it was rejected. Similar patches already do exist: winealsa and wineoss use them, some other sound drivers might use them too. Instead of duplicating that code everywhere I think it's better to add a generic implementation of it that can very easily be changed back to a win32 implementation. What are your thoughts on this?

Yeah, you should use HeapAlloc, and perhaps remove the xmalloc() wrapper :-) . If you test for the existence of xdg-screensaver that way you should close the opened file afterwards. If I remember correctly execvp would check $PATH for the file, so you don't have to hardcode /usr/bin/xdg-screensaver, but I think some "winescreensaver" program simmilar to winebrowser which is configureable via a registry setting would be even better. Also you should return TRUE and FALSE instead of 1 and 0.

Re: [PATCH] initialize pSurface, since we process it on failure

The ICOM_CAST thing should set the output to NULL of the surface returned by ddraw7_CreateSurface is NULL, but ddraw7 doesn't always set it to NULL. I wanted to write a test for this because some calls leave the output pointer untouched if they fail and some set it to NULL. AJ also says we should replace transgamings com casting macros with inline functions.

Current behavior of netapi32-access tests on W2K3 and Vista
by Paul Vriens 12 May '07

12 May '07

Hi, Not so long ago some tests where added for NetUserAdd and friends. While browsing I found that I have about 6 testuser home directories on W2K3 and 4 on Vista (which is the amount of tests I ran on those platforms). Bottom-line is that NetUserDel doesn't delete the home-directory on W2K3 and Vista (which is a good thing) but has no option to delete it explicitly (which is a bad thing IMHO). Any idea how to cleanup after these tests? Just remove the home directory? Cheers, Paul.

As I have still no way to upload the mandriva wine rpm to the official winehq download server. I put it on my own website. So mandriva users you can download the latest wine binaries here: http://www.xs4all.nl/~meijer2/wine/ kind regard, Marco

MAX_STRING_LEN is the maximum length for a string from the resource file, which is totally unrelated to the limit for the length of a subkey name. -- James Hawkins

re: kernel32: Implement most of CopyFileEx
by Dan Kegel 11 May '07

Nice to see somebody filling in the gaps like this. A few nits based on a superficial reading: CopyFileA leaks a string. (I know, it did before your change, too.) copy_file_open_dest's interface comment has the wrong name. + for(i = 0; i < sizeof(flags) / sizeof(flags[0]); i++) + { + if(for_write) { Please use the same whitespace conventions as in the rest of the file (in particular, leave a space after keywords like for and if). + if ((h1 = copy_file_open_source(source, copyFlags & COPY_FILE_OPEN_SOURCE_FOR_WRITE)) == INVALID_HANDLE_VALUE) That line's too long... try to keep them under 80 chars. + // FIXME: total_file_size should include the sum of all streams Use C comments, not C++ comments. + DWORD result = progressRoutine(total_file_size, total_bytes_transferred, stream_size, stream_bytes_transferred, + stream_number, CALLBACK_STREAM_SWITCH, h1, h2, appData); Another instance of line longer than 80 chars. (You have several.) You don't have a conformance test, nor was there one for CopyFile. Maybe you should consider writing one, and making sure it passes both on Wine and Windows. Say, what app is this for? - Dan

Or would a plain This->haveHardwareCursor = FALSE work too? Otherwise looked fine to me
