Hi all, Here is patch for the SHFileOperationW problem. (Which I originally sent out in January. ) It isn't perfect, and it fixes the problem for my application. (which happens to be the same as Lionel's) According to Lionel the fix is better than what is there today, but it falls short of windows behavior in the following manner (for the record): > But it's not 100 % correct as, for example, it does not work if one needs to > create more than one level of directories (which is working fine in Windows, > I just checked it). Moreover, there should be a message box (if not disabled > like in RollerCoasterTycoon) asking if the users wants or not to create the > directory (I checked this on Windows too). --Phil Hewlett-Packard: High Performance Technical Computing/Visualization --------------------------------------------------------------------------- Phillip.Ezolt(a)hp.com Performance/Development ---------- Forwarded message ---------- Date: Fri, 30 Jan 2004 12:54:48 -0500 (EST) From: Phillip Ezolt <phillip.ezolt(a)hp.com> To: wine-patches(a)winehq.org Subject: SHFileOperationW: Create subdir on Copy Hi All, Here's a small fix. Comments/questions are welcomed. Summary ------- This patch allows SHFileOperationW to automatically create subdirectories if they don't exists. (The Microsoft documentation states that this is correct.) This patch fixes bug #1954. I have verified that it works with Today's CVS. (January 30,2004) I ran into this problem with the Rollercoaster Tycoon demo installer. It can successfully copy files to this newly created directory, but coping into any (currently non-existant) directories below it fail. According to MS: (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/pl…) " Copy and Move operations can specify destination directories that do not exist and the system will attempt to create them. " (See footnote #1 for more info) For example, this succeeds: trace:shell:SHNotifyCopyFileW (L"E:\\WZS21db.tmp\\English\\rct.exe" L"C:\\Program Files\\Hasbro Interactive\\RollerCoaster Tycoon Demo\\rct.exe" ) But this fails: trace:shell:SHNotifyCopyFileW (L"E:\\WZS21db.tmp\\Saved Games\\001" L"C:\\Program Files\\Hasbro Interactive\\RollerCoaster Tycoon Demo\\Saved Games\\001" ) The directory "Saved Games" should be created before "001" is copied into it. Instead, the call fails. --Phil Hewlett-Packard: High Performance Technical Computing/Visualization --------------------------------------------------------------------------- Phillip.Ezolt(a)hp.com Performance/Development

msvcmaker - fix building makefiles on Windows
by Steven Edwards May 28, 2004

May 28, 2004

Hello, I am not 100% sure if this is correct as I dont have a Windows box handy and dont know perl but this has been a known bug where msvcmaker did not properly build Makefiles when using Perl on Windows. A anonymous slashdot reader sent me this patch to fix this oversite. He saif to either attribute the changelog entry to Fred Patrik or to me. If someone has a Windows box handy could you test msvcmaker with this patch and see if it generates the makefiles properly now?

Unsupported feature in SHFileOperationW
by Lionel Ulmer May 28, 2004

May 28, 2004

Hi all, A game demo installer uses SHFileOperationA to copy files over... And it expects also the destination directories to be created when the copy is done. Basically, it gives a list of fully qualified source files and their corresponding fully qualified destination files and cann the SHFileOperationA function with the 'FO_COPY' function and 'FOF_MULTIDESTFILES FOF_NOCONFIRMATION FOF_NOCONFIRMMKDIR' flags. This seems to not be handled properly in the current Wine tree as it fails as soon as it needs to create the directory on the destination files. I tested this on Windows and it works just fine (with nice MessageBoxes if one ommits the 'NOCONFIRMMKDIR' flag :-) ). Is anyone (Martin, Ge ?) currently working on Shell32 who has an updated tree with fixes in the Shell file operations ? If not, I will try to fix it on my own (be aware though that as I find the style of coding used in this file particularely hard to decipher, I may do a 'NIH' on it and rewrite most of it to fit my tastes :-) ).

Here X gets it from the monitor at start-up (via the logic of the video card). I did not realize that my situation is not normal. Somehow, I think setting a proper dpi should ideally be done in X.

atoi and undefined usage
by andrejoh＠c2i.net May 27, 2004

May 27, 2004

The atoi() function has undefined usage when trying to convert numbers outside the range of int. When parsing numbers >= 2^31, GNU libc seems to truncate the number to 2^31-1; however, with MSVC, such a number would wrap, and when cast to an unsigned integer, numbers within an unsigned int are preserved. Should Wine care about such undefined behaviour? Currently, it seems Wine uses the GNU libc implementation, giving a different result than when running in Windows. (In my case, an IP address was given as a string, and ended up as "127.255.255.255" when running in Wine. I've now fixed that specific bug in the source code, but with other programs, that might not be an option...) -- Try Anarchy Online http://www.anarchy-online.com/content/downloads/tryout/ Netiquette guidelines ftp://ftp.rfc-editor.org/in-notes/rfc1855.txt How to quote properly http://www.i-hate-computers.demon.co.uk/ Hvordan sitere riktig http://home.online.no/~vidaandr/news/OBSquoting.html

Re: Additional downloads for winehq

OK, I don't see the utility of having a 3rd party download section just to list one download. But what about dcom95? We have a message in oleaut that tells the user to download dcom95, and it provides a link to sf, but we can't host dom on sf because it isn't open source, and people can download it free from m$ anyway. But Alexandre doesn't like long links, and the link to the dcom95 download page is just too long. It's http://www.microsoft.com/downloads/details.aspx?familyid=d7a4de78-81a9-4db7… and we want to keep the error log short. Ivan.

For my understanding the test are created to show that either the > behaviour of wine is correct (when the test succeeds) or that something > left to do one wine (when a test fails)!? check out the todo_wine construct in winetest Alexandre point is not that you cannot add a test that currently fails in Wine. His point is that you cannot add a test that will make the test process fail. The todo_wine is done for that: 1/ it marks a test as failing on wine 2/ it will report it (but not make the test fail) 3/ it will also make the test process fail if the test succeeds (so that we can remove the todo_wine mark) A+

I don't think these belong on the download page. That would confuse the users. IMO the download page should only contain links to download Wine. All this should go in a HowTo or in the docs. I know we have the 3rd party tools section there. I was opposed to that as well. We just cleaned up the download page, and you people want to clutter it up again! <g> Btw, your link to the download page in the second patch in wrong. it should be: http://www.winehq.org/download (we need to keep consistent on the .org thing) On Wed, 2004-05-26 at 18:09, Ivan wrote: > These downloads can be useful for lots of wine users. > > Ivan.
