[PATCH v12 0/2] MR2100: ntdll: Do not send data to port 0.
by Jason Beetham (＠beef331) 08 Feb '23

08 Feb '23

On Windows it seems sending to port 0 does nothing and does not error. Presently sendmsg errors with EINVAL. This works around it, by checking if it's port 0 then skipping the data. -- v12: ntdll: Do not send data to port 0. https://gitlab.winehq.org/wine/wine/-/merge_requests/2100

[PATCH 0/1] MR2141: vbscript: Fix memory leak in owned safearray iterator
by Jason Millard (＠jsm174) 08 Feb '23

08 Feb '23

While running in XCode's profiler, I noticed memory leaks when safearrays were used in `For Each` statements. The following code would leak a safearray allocation: ``` For Each obj In vpDict.Keys : Debug.Print "Key" : Next ``` This following code does not leak: ``` Dim x x = vpDict.Keys For Each obj In x : Debug.Print "Key" : Next ``` Fixes: https://bugs.winehq.org/show_bug.cgi?id=54456 -- https://gitlab.winehq.org/wine/wine/-/merge_requests/2141

WTB might support XP and Vista but those aren't part of the default test set. Nor are they shown on https://test.winehq.org/data/ . The winetest/dissect utility though doesn't marks them as prediluvian. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/2128#note_23521

Sorry, accidentally hit send before I was done writing. Continuing: > + DWORD bytesSent = 0; Not to bikeshed style, but being consistent within the same code would at least be appreciated. (And in new code we tend to avoid camel case.) > + s = socket(AF_INET, SOCK_DGRAM, 0); Let's explicitly use IPPROTO_UDP here, please.

For one thing, I'm not sure all platforms are going to return EINVAL here. Probably better is to either handle it in try_send() before sending, or handle it in sock_send() in about the same place. (I think it'd need to be after the server call, though I haven't properly checked whether the server needs to do anything important here.) Note that you'll also explicitly want to check the protocol here in that case, so we only catch UDP sockets with this logic. Also, please try to match the surrounding code style wrt things like brace placement and spacing. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/2100#note_23505
