int Tablespace_client::alloc_extent ( Local_key * key )

inline

Return >0 if success, no of pages in extent, sets key <0 if failure, -error code

Definition at line 397 of file tsman.hpp.

Here is the call graph for this function:

int Tablespace_client::alloc_page_from_extent	(	Local_key *	key,
		unsigned	bits
	)

inline

Allocated a page from an extent performs linear search in extent free bits until it find page that has atleast bits bits free

Start search from key->m_page_no and return found page in key->m_page_no this make sequential calls find sequential pages

If page is found, then the unlogged "page allocated bit" is set so that page can't be allocated twice unless freed first

Note: user of allocated page should use update_page_free_bits to undo log changes in free space on page

Return <0 if none found >=0 if found, then free bits of page found is returned

Here is the call graph for this function:

int Tablespace_client::free_extent	(	Local_key *	key,
		Uint64	lsn
	)

inline

Free extent

Here is the call graph for this function:

int Tablespace_client::get_page_free_bits	(	Local_key *	key,
		unsigned *	uncommitted,
		unsigned *	committed
	)

inline

Definition at line 466 of file tsman.hpp.

Here is the caller graph for this function:

int Tablespace_client::get_tablespace_info ( CreateFilegroupImplReq * rep )

Get tablespace info

Store result in rep

Return 0 - on sucess <0 - on error

		unsigned	bits
	)

inline

		Uint32	bits
	)

inline
