Chained hashing not working as expected

[blackcoffeerider]

Hello Hajime,

I guess i am doing something wrong - so this is probably not a real issue.
I am trying to hash big files an reading them in chunks for obvious reasons.
As a test i ran the following:

>>> mmh3.hash128('foobar', 0, signed = True)
155033341411922636178181560508455868997
>>> mmh3.hash128('bar',mmh3.hash128('foo', 0,signed = True), signed = True)
144772797738558108830387305245635675932

I expected the hash to be the same in both cases.
Am I missinterpreting the seed value - or is there another way of chaining hashes in murmur in general?

Thanks & Regards,

Martin

Hi Martin,

Sorry for the huge delay in my answer. A seed is there to be used for randomizing the hash function.
The following Stack Overflow article is informative.

As to incrementally feeding chunks of large data, I plan to implement hashlib-compliant interfaces in the next update. (#39)

Thanks,
