Consistent Hashing

Техника консистентного хеширования consistent hashing довольно популярна при создании распределенных систем, тем не менее я не смог найти описания алгоритма на русском языке. Попробую изложить, возможно кому-то пригодится.

Code Refactoring Detection

An idea of feature I would love to see in code review and diff/merge tools.

Consider you are reviewing code changes or making 3-way merge where among various things a name of some method has changed. Personally I don’t want to go through tens of files and check that all usages of method changed accordingly.

I would like to see it in more declarative way. One phrase saying ‘method Foo.bar() has changed to Foo.bar2()’ would be enough. Imagine you could accept this particular change and now tool ignores it making the whole picture clearer.

Say for static object-oriented languages I can imagine a number of refactoring types where this could be useful - method extract, all kind of renames, replacing inheritance with delegation, replacing constructor with factory methods and so on.

How difficult would it be to implement semantic aware diff on top of Intellij IDEA ?
