[PATCH v16 0/5] MR820: Implement application hives
-- v16: kernelbase: Implement RegLoadAppKey. ntdll: Implement REG_APP_HIVE flag https://gitlab.winehq.org/wine/wine/-/merge_requests/820
From: Santino Mazza <smazza(a)codeweavers.com> Pass filename instead of openning a file handle and passing it to wineserver. This will help to simplify future implementations for load_key where we have to keep track of the file to lock it, save it, etc. For example, with application hives. --- dlls/ntdll/unix/registry.c | 18 ++++++++--------- include/wine/server_protocol.h | 5 +++-- server/protocol.def | 2 +- server/registry.c | 37 ++++++++++++++++++++-------------- server/request.h | 1 - server/trace.c | 4 ++-- 6 files changed, 36 insertions(+), 31 deletions(-) diff --git a/dlls/ntdll/unix/registry.c b/dlls/ntdll/unix/registry.c index 797e32a5bf1..a15260d6713 100644 --- a/dlls/ntdll/unix/registry.c +++ b/dlls/ntdll/unix/registry.c @@ -700,7 +700,6 @@ NTSTATUS WINAPI NtLoadKeyEx( const OBJECT_ATTRIBUTES *attr, OBJECT_ATTRIBUTES *f HANDLE event, ACCESS_MASK access, HANDLE *roothandle, IO_STATUS_BLOCK *iostatus ) { NTSTATUS ret;

You've changed the wrong commit, this should be changed in the first one. Also, I suggested that you add a test for `req_data` and return if it's `NULL`. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/820#note_9406
