Function Documentation

compare_log_name()

int compare_log_name	(	const char *	log_1,
		const char *	log_2
	)

Compare log file basenames, i.e.

without their directory names

Returns

It returns an integer less than, equal to, or greater than zero if log_1 is found, respectively, to be less than, to match, or be greater than log_2

exec_binlog_error_action_abort()

void exec_binlog_error_action_abort

(

const char *

err_string

)

When a fatal error occurs due to which binary logging becomes impossible and the user specified binlog_error_action= ABORT_SERVER the following function is invoked.

This function pushes the appropriate error message to client and logs the same to server error log and then aborts the server.

Parameters

err_string

Error string which specifies the exact error message from the caller.

normalize_binlog_name()

bool normalize_binlog_name	(	char *	to,
		const char *	from,
		bool	is_relay_log
	)

Turns a relative log binary log path into a full path, based on the opt_bin_logname or opt_relay_logname.

Also trims the cr-lf at the end of the full_path before return to avoid any server startup problem on windows.

Parameters

from	The log name we want to make into an absolute path.
to	The buffer where to put the results of the normalization.
is_relay_log	Switch that makes is used inside to choose which option (opt_bin_logname or opt_relay_logname) to use when calculating the base path.

Returns

true if a problem occurs, false otherwise.
