git checkout - Git jumping back to history after adding and removing files has different behaviour? -

-

i'm new comer git. found interesting.

say if add file , commit. after checkout previous version, file doesn't exist expected. (since in last commit, hadn't been created)

however, if remove file , commit. after jump previous commit, file doesn't exist well, surprises me.

why there're different behaviours?

thanks

edit: reply. jumped previous commits git log showing hash. , git checkout 'hash'.

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
