Susan Hinrichs updated TS-4820:
-------------------------------
Fix Version/s: 7.0.0
> ParseRules::ink_tolower_buffer seems to be broken
> -------------------------------------------------
>
> Key: TS-4820
> URL: https://issues.apache.org/jira/browse/TS-4820
> Project: Traffic Server
> Issue Type: Bug
> Reporter: Susan Hinrichs
> Assignee: Susan Hinrichs
> Fix For: 7.0.0
>
>
> This function doesn't seem to be used.
> It tries to be clever about unrolling the character copy loop to do word
> aligned assignments. However, its calculation about the number of characters
> to assign to get the pointer to be word aligned is wrong (fpad).
> The assignment in the code is
> {code}
> uintptr_t fpad = 4 - ((uintptr_t)ptr & 3);
> {code}
> I think it should be
> {code}
> uintptr_t fpad = ((uintptr_t)ptr & 3);
> {code}
> I tried using this function while addressing the lower case cert name lookup
> bug, but it didn't work. It only copied the first 8 of 14 characters.
> I grepped the code base and it seems that this function is not used anywhere.
> I would suggest just removing the ink_tolower_buffer function. I think
> compilers are clever enough these days to do the unrolling if it makes sense.
