[Bug 59368] [feature request] Allow app developers to set dlloverrides

by WineHQ Bugzilla

http://bugs.winehq.org/show_bug.cgi?id=59368 mata <sutupud(a)yahoo.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |sutupud(a)yahoo.com --- Comment #1 from mata <sutupud(a)yahoo.com> --- That more or less already exists, and it even supports more than just dll overrides: https://gitlab.winehq.org/wine/wine/-/wikis/Useful-Registry-Keys So, to provide some defaults, a reg file yould be used, for example: Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Wine\AppDefaults\AppName.exe\DllOverrides] "dllName1"="builtin,native" "dllName2"="native" "dllName3"="" ... and imported using: wine reg import fileName.reg Not sure if it really would mare sense to add an additional location to populate the overrides, besides the already existing options via WINEDLLOVERRIDES env variable, the global default registry and the per-application registry. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59329] Erratic behavior of std::rethrow_exception() with DLL runtime

by WineHQ Bugzilla

http://bugs.winehq.org/show_bug.cgi?id=59329 --- Comment #3 from Piotr Pawłowski <p(a)perkele.cc> --- In sample program, moving std::exception_ptr variable OUT of the scope makes bad behavior go away, when the std::exception_ptr outlives all access to the exception object. So std::exception_ptr destructor is prematurely destroying the exception and catch() is use-after-free. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59362] Gdiplus LockBits() flags=0 different behavior than Microsoft implementation

by WineHQ Bugzilla

http://bugs.winehq.org/show_bug.cgi?id=59362 --- Comment #11 from Piotr Pawłowski <p(a)perkele.cc> --- Thanks for all the replies. Tested 10022 against offending foobar2000 build, now works properly, so it's fixed from my point of view. I have been probing how MS gdiplus DLL handles different combination of flags, but it looks like flags=0 case works by accident there - passing ImageLockModeUserInputBuf alone isn't letting me write. So it's probably best we don't attempt more fixes here (such as explicit flags sanitization) until an app that requires such is found in the wild. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
