The function '_SHCreateSymbolicLinks' already exists in master branch, it's defined around line 4250. And originally it was called around line 5961. It's the function that currently reinitializes those "shell folders" in question.
This function is called during registry of shell32.dll, which happens on each wine upgrade/reinstall or when 'wineboot -u' is called. Issue is caused by function SHGetFolderPathAndSubDirW being called for some of shell folders with flag CSIDL_FLAG_CREATE before function _SHCreateSymbolicLinks is called. Thus, when function _SHCreateSymbolicLinks is called, some directories, like Desktop or My documents, may already exist. To overcome that issue and initialize shell folders by proper links, current code just removes current shell folders, and reinitializes them to default locations. And it looks like it only removes current shell folders if they're symlinks or empty directories. This causes the current issue. The proposed registry key solution may circumvent the issue by not allowing the function _SHCreateSymbolicLinks to run on prefix upgrade and remove current symlinks. My patch uses different approach. Instead of removing directories after they're created and recreating them, right before shell directory is being created in function SHGetFolderPathAndSubDirW (which shouldn't happen too often) the initial symlinks setup is performed to make sure that shell folders are properly set up. Since _SHCreateSymbolicLinks calls function SHGetFolderPathAndSubDirW via function SHGetFolderPathW I had to remove flag CSIDL_FLAG_CREATE from calls in that function and correspondingly modify return code checks. Otherwise it'd cause infinite recursion and finally a crash. Well, creation of directory is not what is desired at that point anyway, just it's path is needed. I prefer tabs over spaces for identation, due to that my editors are set up to ident with tabs, and it looks like I added some lines with them. As for directory permissions, I just made them what is usually proposed as safe defaults. Please feel free to modify any parts of patch you think should be modified or use different approach entirely if you think this one is undesired. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/913444 Title: Every wine update re-enables desktop integration links To manage notifications about this bug go to: https://bugs.launchpad.net/wine/+bug/913444/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
