#1836 closed defect

use leasedb (not crawler) to figure out how many shares you have and how many bytes — at Version 6

Description (last modified by zooko)

In current trunk, there is a "BucketCountingCrawler" whose job it is to count up how many shares are stored.

I propose that this be replaced by using the leasedb to count files (a simple SQL COUNT query!), and at the same time to extend the storage server's abilities by letting it be able to add up the aggregate sizes of things as well as their number.

This is part of an "overarching ticket" to eliminate most uses of crawler — ticket #1834.

The part about reporting total space usage would be very useful for customers of LeastAuthority.com (who pay per byte), among others.

  • Summary changed from stop crawling share files in order to figure out how many shares you have to use leasedb (not crawler) to figure out how many shares you have and how many bytes

Using leasedb this way would facilitate solving #671 — bring back sizelimit (i.e. max consumed, not min free).
