/*
* Zotlabs\Lib\Hashpath
*
* Creates hashed directory structures for fast access and resistance to overloading any single directory with files.
*
* Takes a $url which could be any string
* a $prefix which is where to place the hash directory in the filesystem, default is current directory
* use an empty string for $prefix to place hash directories directly off the root directory
* an optional $depth to indicate the hash level
* $depth = 1, 256 directories, suitable for < 384K records/files
* $depth = 2, 65536 directories, suitable for < 98M records/files
* $depth = 3, 16777216 directories, suitable for < 2.5B records/files
* ...
* The total number of records anticipated divided by the number of hash directories should generally be kept to
* less than 1500 entries for optimum performance though this varies by operating system and filesystem type.
* ext4 uses 32 bit inode numbers (~4B record limit) so use caution or alternative filesystem types with $depth above 3.
* an optional $mkdir (boolean) to recursively create the directory (ignoring errors) before returning
*
* examples: for a $url of 'abcdefg' and prefix of 'path' the following paths are returned for $depth = 1 and $depth = 3
* path/7d/7d1a54127b222502f5b79b5fb0803061152a44f92b37e23c6527baf665d4da9a
* path/7d/1a/54/7d1a54127b222502f5b79b5fb0803061152a44f92b37e23c6527baf665d4da9a
*
* see also: boot.php:os_mkdir() - here we provide the equivalent of mkdir -p with permissions of 770.
