另外,DeepDiff倾向于使用Murmur3进行哈希处理。但是,您必须通过运行以下命令手动安装Murmur3: pip install 'deepdiff[murmur]' 否则,DeepDiff将使用SHA256进行散列,这是加密散列,并且速度相当慢。 deepdiff[murmur]安装遇到问题参考:https://deepdiff.readthedocs.io/en/latest/#troubleshoot DeepDiff在单元测试中的应用 先...
DeepHash的核心是将对象确定性序列化为字符串,以便可以将其传递给哈希函数。默认情况下,它使用Murmur 3 128位哈希函数。但是您可以根据需要将另一个哈希函数传递给它。 来看示例: fromdeepdiffimportDeepHashobj = {1:2,'a':'b'}# hash(obj) # TypeError: unhashable type: 'dict' 我们试图hash上述的字典,但...
根据murmur3_128方法的到一个 128 位长度的byte[]。 分别取高低 8 位的到两个hash值。 再根据初始化时的到的执行hash的次数进行hash运算。 bitsChanged |= bits.set((combinedHash & Long.MAX_VALUE) % bitSize); 其实也是hash取模拿到index后去赋值 1. ...

我在java(jedis和番石榴)、go和python中尝试了三个版本的murmurhash。java(番石榴)、go和python版本的结果输出相同的哈希代码,但与java(jedis)不同。int64(murmur3.Sum64WithSeed([]byte("foo"), 0x1234ABCD))输出:3.python版本importmmh3 foo = <e ...
