<div dir="ltr"><div>If people like this change, I'll do the same thing to the hash set implementation. </div>--Jason </div><div class="gmail_extra"> <div class="gmail_quote">On Mon, Nov 24, 2014 at 10:19 PM, Jason Ekstrand <<a href="mailto:jason@jlekstrand.net" target="_blank">jason@jlekstrand.net</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Previously, the hash_table API required the user to do all of the hashing of keys as it passed them in. Since the hashing function is intrinsicly tied to the comparison function, it makes sense for the hash table to know about it. Also, it makes for a somewhat clumsy API as the user is constantly calling hashing functions many of which have long names. This is especially bad when the standard call looks something like _mesa_hash_table_insert(ht, _mesa_pointer_hash(key), key, data); In the above case, there is no reason why the hash table shouldn't do the hashing for you. We leave the option for you to do your own hashing if it's more efficient, but it's no longer needed. Also, if you do do your own hashing, the hash table will assert that your hash matches what it expects out of the hashing function. This should make it harder to mess up your hashing.
