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 | 12 ++------ include/wine/server_protocol.h | 5 ++-- server/protocol.def | 3 +- server/registry.c | 53 +++++++++++++++++++--------------- server/request.h | 2 +- server/trace.c | 3 +- 6 files changed, 40 insertions(+), 38 deletions(-)

Oh interesting, where do you find those headers in the windwos sdk? I've tried to find something like that but I'm always afraid of breaking the clean room guidelines.
I usually just google the header file name + source, then google usually just gives me the full header file on github

Yeah I've also tried that but couldn't find it, probably I just didn't search enough. lol
Huw Davies (@huw) commented about dlls/ntdll/unix/registry.c:
SERVER_START_REQ( load_registry ) {
req->file = wine_server_obj_handle( key );
req->access = access; wine_server_add_data( req, objattr, len );wine_server_add_data( req, unix_name, strlen(unix_name) + 1 );
The server can't safely rely on nul-terminated strings, so just pass `strlen( unix_name )` here (and add spaces either side of `unix_name`). You'll have to make a nul-terminated copy on the server-side to pass to `fopen`.
Huw Davies (@huw) commented about server/registry.c:
unsigned int flags; /* flags */ timeout_t modif; /* last modification time */ struct list notify_list; /* list of notifications */
- FILE *file; /* loaded file */
This doesn't appear to be used at this point.
Related to this, and as mentioned last time, did you look at the adapting the existing 'save_branch_info' code?

But as I understand, if we can use strlen in unix_name, that means its a null terminated string and wine_server_add_data should append data to the server request including the null terminator, becuase of strlen( unix_name ) + 1. So in the server side we should receive that null terminator when using get_req_data_after_objattr.

The point is that the server shouldn't assume that the client has correctly nul-terminated the string (to guard against a wayward client). That being the case, there's no point in sending the '\0' in the first place.

Oh didn't think of that, makes sense.

Oh sorry I forgot about looking into 'save_branch_info'. I saw that this is only used with the initial root hives loading and already uses filenames instead of file objects, also I've read that you mean load and save logic in general and the save_registry request still uses file objects, should I adapt that code to use filenames?
