.. Allowing it to be used by things in constant space! Random statistics: git annex status has gone from taking 239 mb of memory and 26 seconds in a repo, to 8 mb and 13 seconds. The trick here is the unsafeInterleaveIO, and the form of the function's recursion, which I cribbed heavily from System.IO.HVFS.Utils.recurseDirStat. The difference is, this one goes to a limited depth and avoids statting everything. |
