With string code, I like to be more specific if I can to avoid people accidentally passing in UChar* to a function like this. I was trying to side step the three different types for bytes and was a little bit influenced by the types in NSData methods. But your argument seems compelling, and CFData functions take uint8_t*. I will go with uint8_t instead. 1733578 4 darin 2021-02-25 16:08:13 -0800 Looks like Brent’s patch had to be rolled out. I’ll have to wait to land this until it’s landed again. 1736064 5 webkit-bug-importer 2021-03-04 15:38:22 -0800 <rdar://problem/75061347> 1736480 6 darin 2021-03-05 12:41:52 -0800 Not needed any more. Brent’s latest is using CFURLCreateAbsoluteURLWithBytes now, not URLWithData, so there’s no need for this. 421577 2021-02-25 15:46:57 -0800 2021-02-25 15:56:11 -0800 Patch
