b16ff123b7 [thin] Stop metadata counting on the first error 2020-08-12 15:56:26 +08:00
Ming-Hung Tsai
12725983db [block_counter] Add the stop-on-error option to prevent silent errors 
The stop-on-error option aims to solve the lack of damage_visitor support
in space_map::count_metadata and btree counting_visitor. To prevent
possibly silent errors during space map or btree counting, the option
stops the counting process immediately when a btree or bitmap error
was found.

The bitmap blocks are also validated to avoid potential false-alarm,
if broken bitmap is not counted, and the corresponding ref-count is
also zeroed.
