GDI.EXE
by Johan Gill Feb. 19, 2001

Feb. 19, 2001

Since some apps require a gdi.exe file containing version info, Wine won't be independent until the need for a true gdi.exe is removed. Are there any plans on how this should be achieved? /Johan Gill, johane(a)lysator.liu.se

Re: Overlapped read/write fix

Overlapped read and write is supposed to be allowed for sockets and serial ports even on win9x, but for ordinary files only on winNT, as far as I remember.

Should we be preserving the values of he, se, pe in the delete? This fixes a problem Jutta Wrage was having with Agent mailreader(win16 app).

Wine & Wrapster/UnWrapper/etc
by David Luyer Feb. 19, 2001

Feb. 19, 2001

Just a potentially useful data point, since the Wrapster source is freely available on their website (it's written in PASCAL). Wrapster and UnWrapper won't work under WINE 20010112. Wrapster appears to sit in an infinite loop when asked to unwrap a file (although it's a 180Mb+ file so it may be doing something, but strace implies it's sitting there being confused, since it continually lstat()'s the destination directory and then does some miscellaneous memory mapping and unmapping). UnWrapper (2.x and 3.x) simply die on startup. (And yes, I know there's a Linux version - but it doesn't do a fraction of what the Windows version does, eg, CRC checks and new file formats. So I was hoping to check if the archive I have was corrupt without having to do development on grapster first... other than the fixes I already had to do to get dewrapster to handle large files :-).) I am no longer on this list, so please CC any response to me (especially of the form "it actually works with the latest CVS and some custom patch" :-)), thanks in advance. David. (I wonder how PC-PINE is working these days, it's C source was available and it used to not work so well under WINE either...) -- David Luyer Phone: +61 3 9674 7525 Senior Network Engineer P A C I F I C Fax: +61 3 9699 8693 Pacific Internet (Australia) I N T E R N E T Mobile: +61 4 1111 2983 http://www.pacific.net.au/ NASDAQ: PCNTF

Bad rumors still abound about sendmail anyway, so I just installed exim... hopefully this won't cause problems...

EnumPrinterDataEx - one more time

Feb. 19, 2001

Here is an updated patch that does not use any macros. I do check all the return values, but hopefully this can be written off as a personal quirk. If no one has any objections, I'll send this to wine-patches tomorrow.

Keyboard events and Direct Draw
by Alan Chandler Feb. 18, 2001

Feb. 18, 2001

Actually this is NOW the third attempt the other attempts were yesterday. Apologies to everyone if they have already seen the following. I posted it several hours ago, but I would have expected it to have bounced back to me from the list by now, but it hasn't... ... and I also wanted to add, that I have been desperately trying to find a way to put a breakpoint on any events coming from the keyboard to try and track where they go - but nothing. I cannot find any evidence of any keyboard events being received within wine at all. With --debugmsg traces on channels "key", "keyboard" or "event", I can find nothing registered as I press a key. Perhaps more problematic since its also using the keyboard, but winedbg is not breaking on a breakpoint set on X11DRV_KEYBOARD_HandleEvent The following ... I am trying to understand the behaviour of wine when running Grand Prix Legends (a racing car simulator) - called GPL below. I posted here last week, and since then some updates have occurred to wine that improve things. Namely the colours now all come out correct. However, I am still trying to find out why key presses don't get fed into the program. This has the unfortunate affect, that once you have told the program to exit, you have to wait several minutes for the credits to scroll by since in the program under Windows, hitting return is the only way to kill these off. This is made worse by the fact that the DirectDraw window created by the program forceses itself on top of all the others so that whilst is there most ofther windows are fully or partially obscured (on any virtual desktop). This makes further debugging extremely difficuly. I am pretty sure the program (GPL) is not trying to use direct input for the keyboard, which implies it is expecting keypress messages on its winproc queue. However I don't know which one. With use of --debugmsg I think it creates one window, and then uses a Direct Draw call SetCooperativeLevel to set this window to full screen and exclusive mode. This window is then made active. Inside wine, dlls/ddraw/dsurface/user.c - there is a routine called when a direct draw surface is to be created. Last week Gavriel State suggested that I look at the #define OWN_WINDOW and comment it out. I tried that, and if I do, the game produces no output. However, when this #define is defined I do get the proper output (I have set the game and wine to only assume a 640x480 screen so its a window created in the upper left of my screen). Mouse events are captured properly, but keyboard events do not seem to be. Instead they seem to be directed at the underlying window from which wine was started (or if running winedbg the debug window). Looking at the code within the dsurface/user.c file, it appears to me that keyboard events received are passed to the orginal DirectDraw window. Therefore I don't understand why its not working. I guess the question I am asking is what are the differences between windows and wine here - I have very little knowledge of windows or x windows operation (other than what a learned about windows 5 years ago by reading manuals - but never actually writing code) so forgive me - and what could GPL doing to actually get keypresses. Some thoughts a) There is a call in the trace "CreateDesktopWindow" a little before the other windows calls. Is this Wine or GPL creating this window b) When I run the game under Windows you can ALT-TAB between two tasks. Maybe this other task has a dummy window taking keypresses and that somehow wine is not emulating windows behaviour correctly when automatically linking keypresses to the DirectDraw window Any comments?

The alignment requirement of a structure is the maximum (well, least common multiple) of the alignment requirements of all its member. #pragma pack(1) says that for all subsequent struct definitions, every member's alignment requirement is artificially set to 1. Hence, the struct's alignment requirement is also 1 ... Bye, Ulrich -- Dr. Ulrich Weigand weigand(a)informatik.uni-erlangen.de

winehq mailserver troubles
by Ove Kaaven Feb. 18, 2001

Feb. 18, 2001

Looks like mail to winehq was refused since yesterday because 30 sendmail processes was hung trying to deliver mail to some guy at ameritech.net (timed out connections etc), and since this was a limit in sendmail, it refused further incoming connections, and the secondary mailserver at corel didn't want winehq mails, so all incoming mails have been bounced by it... you'll probably all need to resend any bounced mails, I think. But it seems the hanging sendmail processes are already building up again. Let's see... should I disable the culprit's subscription, or try to compile a newer sendmail (if available), or maybe install some other MTA software, like exim? Hmm...

Perl/Wine extension for perusal
by John F Sturtz Feb. 17, 2001

Feb. 17, 2001

Greetings. I work for CodeWeavers here in St Paul. Awhile back, I was set to the task of working on winetest, a Wine application which provided a flex/bison-based parser for a little scripting language from which Wine API functions could be called. The idea was that one could write test scripts which would call Wine API functions and examine the results, and the scripts could be used for regression testing of Wine. The scripting language began life with a rather Perl-ish syntax, and as functionality got added, it got more so. Eventually (about the time I had implemented a pack function, and wanted an unpack), I decided to see if I could write a Perl extension that provided a gateway for calling Wine API functions. That way, scripts for regression testing could be written directly in Perl instead. I have an initial version done. The practical upshot is that from a Perl script (after going through the proper incantations), you can write something like this: $atom = kernel32->GlobalAddAtomA("bark"); and the script will call the Wine GlobalAddAtomA() function, passing the string "bark", and return the result in $atom, which can then be examined to determine if it's what it should be. At Alexandre's suggestion, I've tossed a tarball of the stuff out on wine.codeweavers.com at ftp://wine.codeweavers.com/pub/other/perlwine.tar.gz for anyone who's interested in having a look (just download the tarball, untar/ungzip it, and look at the README to get started). In particular, I'm curious as to: 1) Whether it works for anyone who tries it 2) Whether there's anyone who is both a serious Perl guru and a serious Windows guru (I am marginally the former and nowhere near the latter) who might like to take a stab at getting the extension to work under Windows Perl. 3) Whether any make guru would want to take a stab at writing a real makefile for the package (as opposed to the hack make ksh script I've done) as well as any other comments. Any input is appreciated. Thanks. John Sturtz jsturtz(a)codeweavers.com
