git - How to prevent losing .gitignore when checking-out older branches? -

-

if in master , stuff want safe git ignored, then:

    git checkout <oldbranch or commit>

but old branch doesn't have ignored files arrgh! untracked files added etc , vulnerable reset --hard etc.

is there more elegant fix here other than:

    git checkout master .gitignore     #maybe write hook every checkout of <oldbranch or commit>?

or manage copying .gitignore .git/info/exclude?

adding rules in .git/info/exclude 1 way, remains local workaround: won't pushed .gitignore file would.

the best option remains create .gitignore in checked out branch:

git checkout abranchwithoutgitignore git checkout master -- .gitignore git add .gitignore git commit -m "add .gitignore master"

then cherry-pick commit other branches.

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
