nsCRT::BufferHashCode has two variants, and only one consumer, one could be removed. The consumer (http://lxr.mozilla.org/seamonkey/source/content/shared/public/nsHTMLValue.h#140 ) uses the char*-version but maybe it should use the PRUnichar*-version? Anyway, one of these variants could be removed.

It also looks like HashCodeAsUTF8 has no consumer at all. http://lxr.mozilla.org/seamonkey/search?string=HashCodeAsUTF8

Comment on attachment 155374 [details] [diff] [review] patch Hmm... changing to the wide version of BufferHashCode appears to change the hashing algorithm since it will be combining 16-bit units instead of 8-bit units, or am I mistaken? I can't see any reason why that should matter, unless some other code elsewhere is using PL_HashString or some other implementation of the same algorithm as the narrow version of BufferHashCode. Are we 100% sure this isn't going to cause wierd side-effects? I find it odd that jkeiser added the wide version of BufferHashCode at the same time that he added this HashCode function. Do you think he just mistakenly used the narrow version to begin with? (It did go through 3 reviewers... chalk it up to a typo or could there be some real reason behind his choice?) Also, seems like a shame to throw away such good code for computing the UTF-8 equivalent hash on a UTF-16 string. Maybe we should just "#if 0" the code in case someone needs it again? r=darin

Argh! I'm using HashCodeAsUTF8(). timeless, it'd been nice if you'd followed darin's sr commeints before checking this in...
