Re: Very large files

I tested it (code to copy a file below, file was > 4 GB) and it works. I'm using Gentoo 2006.0, Linux 2.6.15.1, ReiserFS 3 and wine 0.9.15. Can you find out whether the broken code is using KERNEL32, NTDLL, MSVCRT streams or MSVCRT POSIX-style open()/read() etc.? #include <windows.h> #include <stdio.h> int main(int argc, char **argv) { HANDLE inputFile = INVALID_HANDLE_VALUE, outputFile = INVALID_HANDLE_VALUE; const int bufferSize = 8*1024; char buffer[bufferSize]; DWORD bytesRead; BOOL ok; if (argc < 3) { fprintf(stderr, "Usage: %s source destination\n", argv[0]); return 1; } inputFile = CreateFile(argv[1], GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, 0, NULL); if (inputFile == INVALID_HANDLE_VALUE) { fprintf(stderr, "Error opening %s\n", argv[1]); goto done; } outputFile = CreateFile(argv[2], GENERIC_WRITE, 0, NULL, CREATE_ALWAYS, 0, NULL); if (outputFile == INVALID_HANDLE_VALUE) { fprintf(stderr, "Error opening %s\n", argv[2]); goto done; } ok = ReadFile(inputFile, buffer, bufferSize, &bytesRead, NULL); if (!ok) { fprintf(stderr, "Error reading file\n"); goto done; } while (bytesRead > 0) { DWORD bytesWritten = 0, bytesWrittenNow; do { ok = WriteFile(outputFile, buffer, bytesRead, &bytesWrittenNow, NULL); if (!ok) { fprintf(stderr, "Error writing file\n"); goto done; } bytesWritten += bytesWrittenNow; } while (bytesWritten < bytesRead); ok = ReadFile(inputFile, buffer, bufferSize, &bytesRead, NULL); if (!ok) { fprintf(stderr, "Error reading file\n"); goto done; } }; done: if (inputFile != INVALID_HANDLE_VALUE) CloseHandle(inputFile); if (outputFile != INVALID_HANDLE_VALUE) CloseHandle(outputFile); return 0; } --- John Willis <jswillis93105(a)verizon.net> wrote: > Damjan, > > Linux kernel: 2.4.21-20.ELsmp > Filesystem: ext3 > > Thanks for looking into this for me, > > John > > ----- Original Message ----- > From: "Damjan Jovanovic" <dj015(a)yahoo.com> > To: "John Willis" <jswillis93105(a)verizon.net>; > <wine-devel(a)winehq.org> > Sent: Sunday, June 25, 2006 11:31 PM > Subject: Re: Very large files > > > > > > > > --- John Willis <jswillis93105(a)verizon.net> wrote: > > > >> Howdy, > >> > >> I have a large VS 6.0 C++ program and I'm running > it > >> under WINE under Redhat Linux. > >> Everything works fine, but it doesn't handle file > >> sizes greater than 4gb like it can running > >> directly under Windows XP. > >> I've tweaked everything that I can find that > seems > >> to deal with file sizes. > > > > How do you access the file?

Re: [AppDb] [Resend] errorpage -> show_error_page
by Chris Morgan 28 Jun '06

Can we put a module prefix on this function so it is easier to locate in the tree? I'm not sure what but it seems like we should try to prefix something that matches the file the function is in.

Re: [AppDb] automatic variable cleanup
by Chris Morgan 28 Jun '06

28 Jun '06

Wow, thats a pretty neat idea. A few comments. We should do something to the values in $_REQUEST so they can't be used after this function is called. We should error if there are variables that don't fit the format we expect. We can't have anything getting past this filter by default or we'll be opening holes in the filtering without any kind of notification. We'll also want to know if we've missed anything during our changes. Html keyword should probably be 'sh' instead of 'sH' so the lower case characters prefixed on a variable are what represents the variables type. This would be more consistent with what we have. Filtering all variables might let us support allowing magic quotes although given the widespread rejection of the magic quotes feature it seems silly to do so. I wouldn't be surprised if the switch was removed from php entirely in the near future.

I'd suggest to get rid of ghInst altogether until there is a real need for it. -- Dmitry.

For a start, the members of this structure need to be cleaned up. Some of the members of the POPUPMENU structure are for keeping track of the menu while it's in use (bTimeToHide, bScrolling, nScrollPos, FocusedItem), so these could be kept on the client side. Also, everything needs to be converted to wineserver types. It should become clear what needs to change as menu item handling is moved into the server, so I would urge you to work on that and then rework these patches. Thanks, -- Rob Shearman

Wine developers?
by Jonathan Clark 27 Jun '06

27 Jun '06

Hello All, My name is Jonathan Clark, and I work with a team on a project that has some similarities with Wine. The project is called Thinstall (http://thinstall.com), and on first glance similarities may not be apparent. Thinstall allows Win32 applications to run (on Windows) from a network share or usb flash drive with zero install. It isn't meant to allow applications to run cross platform like wine, but it is similar in that it replaces the Windows loader for loading EXEs & DLLs, doing things like mapping, imports, and thread/process management. It also replaces ~400 Win32 api functions in order to allow applications to run instantly in a sandbox so they don't need to touch the local filesystem or registry. Our approach is all in user mode so that applications can run under any login account without needing admin rights or drivers. Thinstall packages the entire application into a single EXE file and then tacks on it's runtime (300k on disk) so apps can be distributed and run as a single file that doesn't need to decompress to disk. The challenges in creating Thinstall are many of the same ones that Wine faces, achieving a high degree of compatibility in replacement functions means you need to be good at debugging and understanding the internals of Windows. Since most code can be run by multiple threads, it is also important to understand thread safety and have a lot of experience working through these types of issues. Thinstall is now about 6 years old and we are coming up on a version 3.0 release. Thinstall is a commercial product and everyone works full time with funding coming from our customers. Recently we've done fairly well financially and have the opportunity to try to take the product and company to the next level by hiring a couple of senior engineers. This brings me to why I'm posting here.. If you are experienced with Windows internals, have experience reimplementing Win32 APIs, and you are interested in some contract or full-time work please let me know. We are located in San Francisco, California (awesome town) and ideally I'd like to work with people locally. We can help with a move if needed. Otherwise, if you are outside of the USA - we could talk about doing something remotely. I hope to hear from you. Best Regards, Jonathan Clark P.S. As background info, I used to be heavily in the linux space when I co-founded a video game company "Crack dot com" which made the linux port of Doom & Quake as well as developed the original titles Abuse and Golgotha. I have been aware of wine for a long long time and I'm impressed by the quality of work by all the developers and how far it has come. P.S.S. I subscribed in digest mode so if you reply to the list, keep in mind I won't see it until tomorrow.
