ibool fil_space_struct::is_being_deleted

this is set to TRUE when we start deleting a single-table tablespace and its file; when this flag is set no further i/o or flush requests can be placed on this space, though there may be such requests still being processed on this space

ibool fil_space_struct::is_in_unflushed_spaces

TRUE if this space is currently in unflushed_spaces

Referenced by fil_flush(), and fil_space_create().

rw_lock_t fil_space_struct::latch

latch protecting the file space storage allocation

FIL_SPACE_MAGIC_N

Definition at line 233 of file fil0fil.cc.

ibool fil_space_struct::mark

this is set to TRUE at database startup if the space corresponds to a table in the InnoDB data dictionary; so we can print a warning of orphaned tablespaces

ulint fil_space_struct::n_pending_flushes

this is positive when flushing the tablespace to disk; dropping of the tablespace is forbidden if this is positive

Referenced by fil_delete_tablespace(), fil_flush(), and fil_space_create().

ulint fil_space_struct::n_pending_ibuf_merges

this is positive when merging insert buffer entries to a page so that we may need to access the ibuf bitmap page in the tablespade: dropping of the tablespace is forbidden if this is positive

ulint fil_space_struct::size

space size in pages; 0 if a single-table tablespace whose size we do not know yet; last incomplete megabytes in data files may be ignored if space == 0
