- Affects the following functions: + `std.fs.Dir.readLinkW` + `std.os.windows.ReadLink` + `std.os.windows.ntToWin32Namespace` + `std.posix.readlinkW` + `std.posix.readlinkatW` Each of these functions (except `ntToWin32Namespace`) took WTF-16 as input and would output WTF-8, which makes optimal buffer re-use difficult at callsites and could force unnecessary WTF-16 <-> WTF-8 conversion during an intermediate step. The functions have been updated to output WTF-16, and also allow for the path and the output to re-use the same buffer (i.e. in-place modification), which can reduce the stack usage at callsites. For example, all of `std.fs.Dir.readLink`/`readLinkZ`/`std.posix.readlink`/`readlinkZ`/`readlinkat`/`readlinkatZ` have had their stack usage reduced by one PathSpace struct (64 KiB) when targeting Windows. The new `ntToWin32Namespace` takes an output buffer and returns a slice from that instead of returning a PathSpace, which is necessary to make the above possible. |
