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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
