exec-shield workaround take 3
by Mike McCormack April 13, 2004

April 13, 2004

Hi, Here's a new patch for exec-shield. Changes against the last patch: * reserve only the area required by the PE EXE if launched from CreateProcess (else just a default slab) * pass the reserved area to wine, so wine knows about it * unmap the preloader after it is no longer used Again, comments, improvements, flames and test reports are all welcome! Mike ----------------------------------------------------------------------- Hi, This patch works around the exec-shield problems with Fedora Core. I'd be greatful if any people using Fedora core could test it out and see how it works. It should be enough to apply it to the latest CVS tip and recompile. All comments and flames accepted... /me wears his asbestos suit.

[PATCH] SHLWapi fixes - Need cleanup
by Flameeyes April 13, 2004

April 13, 2004

Hi, Some time ago I fixed some stubs on SHLWapi lib, but the patch needs some cleanup. I haven't the time to do them (because they are not "natural" for me, and when I tried to post the cleaned up version I missed a lot of cleans. If someone can take a look at it, clean it up and possibly merge it, the patch can be downloaded from http://flameeyes.web.ctonet.it/patches/wine-shlwapi_20031219.diff . Should apply well also in the current version, because it never created conflicts with code in CVS. HTH -- Flameeyes <dgp85(a)users.sourceforge.net> http://flameeyes.web.ctonet.it/

Wine-20040408 Results (so far) for MFC App
by greensh＠knology.net April 13, 2004

April 13, 2004

Now it works very nicely... I spent Easter debugging most of the crashes I was having due to the GUI menus (even in winders), from variables not freed, etc and now I cannot get it to crash...yet. I'm using MSVC6 for all the development under VMware 4.5.1. The GUI code is completely MFC with 16 color bitmaps for resources and all underlying solver code, etc is C++/C. This code puts a P4 laptop and memory under moderate load when run... so it's a good test. Below are the ONLY messages I get from Wine-20040408 when I run it from the command-line; wine sokoban.exe (then it opens the GUI) and then do many things with it; data file I/O, parsing many text files, GUI menus, clicks, etc. As you can see below the help file opens fine, but does not display text properly. I used Shalom Help (free) for winders (it works fine on winxp as I've tested). Any ideas why these messages appear and how to prevent them? I can send app screenshots and provide code snippets. Below these is my entire wine config. fixme:dc:LockWindowUpdate (0x10029), partial stub! fixme:dc:LockWindowUpdate ((nil)), partial stub! fixme:dc:LockWindowUpdate (0x10029), partial stub! fixme:dc:LockWindowUpdate ((nil)), partial stub! fixme:dc:LockWindowUpdate (0x10029), partial stub! fixme:dc:LockWindowUpdate ((nil)), partial stub! fixme:winhelp:HLPFILE_UncompressRLE Null length 2, next is 0 fixme:winhelp:HLPFILE_UncompressRLE Null length 2, next is 140 fixme:winhelp:HLPFILE_UncompressRLE Buffer X-flow: d(108628) instead of d(108640) fixme:dc:LockWindowUpdate (0x10029), partial stub! fixme:dc:LockWindowUpdate ((nil)), partial stub! fixme:dc:LockWindowUpdate (0x10029), partial stub! fixme:dc:LockWindowUpdate ((nil)), partial stub! fixme:dc:LockWindowUpdate (0x10029), partial stub! fixme:dc:LockWindowUpdate ((nil)), partial stub! fixme:dc:LockWindowUpdate (0x10029), partial stub! fixme:dc:LockWindowUpdate ((nil)), partial stub! ~/.wine/config: [Drive C] "Path" = "/home/greensh/.wine/c" "Type" = "hd" [Drive D] "Path" = "/mnt/cdrw" "Type" = "cdrom" ; make sure that device is correct and has proper permissions !

Windows installer XML (WiX) released on sourceforce by Microsoft
by David.Goodenough＠DGA.co.uk April 13, 2004

April 13, 2004

Given the problems that Wine has had with Installers, had anyone noticed that WiX has now been released by Microsoft (under the CPL license) on Sourceforge. http://seattlepi.nwsource.com/business/168652_msftnotebook12.html It seems to be accessible as http://wix.sf.net, but that redirects to a blog site on http://blogs.msdn.com/robmen/category/4625.aspx.

The file stuff is going to be removed anyway, so I'm not sure there's much point in splitting the file. File I/O has to be done by the Linux kernel, we can't do it right in userspace. -- Alexandre Julliard julliard(a)winehq.org
