But i don't quite get it yet. git push --force is not supposed to be a straightforward, or even common operation, as it can destroy history. And selecting/enforcing a ranching schemes is a problem you'll run into with every other SCM in existence.

I'll admit that git gives you enough tools to shoot yourself in both foots if you're willing to, but it also provides very straightforward, easy to use commands for everyday operations. Anyone proficient in SVN can pick up git in 20'.

I've been using git on and off for a while and, honestly, it is the most developer-friendly SCM out there. Which kind of problems do you refer to?

My main pet peeve with git is that it really doesn't work well with big repositories, large number of users, or binary files. Other than that it is a joy to work with.

FWIW, you're correct, but "hash function" englobes much more than that. Technically, a CRC is, by definition, a hash function. So is bit parity.

A cryptographic hash function has the properties you mention, plus the fact that it must not be easily reversible and uniformly distribute results over its entire output space.

Comment Re:Using SHA-1 in this day and age is just lazy (Score 1) 182

It's arguably a major Bug in Git if the Git software keeps track of an object Solely by Hash, and lazily assumes that the Hash
uniquely identifies a specific version of the file, And that assumption turns out to be false, and data corruption or tampering can be caused as a result.

I disagree, this is not a bug. It is perfectly reasonable to use a crypto hash to uniquely identify objects within a SCMs, given that one of their properties is that they provide uniformly distributed IDs over a very large space. Statistically the chance of running into a SHA1 collision under normal git usage is so low as to be practically zero - you have a (much, much) better chance of experiencing repo corruption due to cosmic rays hitting your HDD or memory.

Anyway, git's failure mode is not horrible either in that scenario: http://marc.info/?l=git&m=1156...
