Member Function Documentation

Uint64 Logfile_client::add_entry	(	const Change *	src,
		Uint32	cnt
	)

for callback_buffer, always allocats 2 extra... not knowing if LSN must be added or not

Definition at line 2400 of file lgman.cpp.

int Logfile_client::get_log_buffer	(	Signal *	signal,
		Uint32	sz,
		SimulatedBlock::CallbackPtr *	callback
	)

Check for space in log buffer

return >0 if available 0 on time slice -1 on error

Definition at line 1621 of file lgman.cpp.

Here is the caller graph for this function:

int Logfile_client::sync_lsn	(	Signal *	signal,
		Uint64	lsn,
		Request *	req,
		Uint32	flags
	)

Make sure a lsn is stored

Returns

-1, on error 0, request in queued >0, done
