Files with equal hashes collide
When there are two files with the same hash, they will both be treated as the same file. While hash collisions are rare, this may need to be handled for that case.
I think something like objects/<same hash storage system>/<name> would fix it. That's close to what gradle does.
That's a lot of folders, though I guess it doesn't really matter.
Technically this could reasonably still result in a collision too...
Yes, but I don't think that files that differ internally, but have the same hash and are called the same thing are very common. You could do two hashes:
hash1='abcd'
hash2='1f2f'
folderName=hash1[:2] + '/' + hash2[:2] + '/' + hash1 + '-' + hash2 + '/' + file.name
(I'm pretty sure two hashes at full length have about 0% collision, so you could do without the file name now.)
I might just make it configurable. --hash "sha1[:2]/md5[:2]/sha1/md5" or something.
Perhaps the builder could see two files with the same hash and double hash instead. As for files that get updated but still have the same hash, make it equal to hash(file hash + file date/time + file size)
