Function Documentation

bool get_file_options_ulllist	(	const char *&	ptr,
		const char *	end,
		const char *	line,
		uchar *	base,
		File_option *	parameter,
		MEM_ROOT *	mem_root
	)

Parser for FILE_OPTIONS_ULLLIST type value.

Parameters

[in,out]	ptr	pointer to parameter
[in]	end	end of the configuration
[in]	line	pointer to the line begining
[in]	base	base address for parameter writing (structure like TABLE)
[in]	parameter	description
[in]	mem_root	MEM_ROOT for parameters allocation

Here is the caller graph for this function:

const char* parse_escaped_string	(	const char *	ptr,
		const char *	end,
		MEM_ROOT *	mem_root,
		LEX_STRING *	str
	)

parse \n delimited escaped string.

Parameters

ptr	pointer on string beginning
end	pointer on symbol after parsed string end (still owned by buffer and can be accessed
mem_root	MEM_ROOT for parameter allocation
str	pointer on string, where results should be stored

Return values

0	error
\::	pointer on symbol after string

Here is the caller graph for this function:

my_bool read_escaped_string	(	const char *	ptr,
		const char *	eol,
		LEX_STRING *	str
	)

read escaped string from ptr to eol in already allocated str.

Parameters

ptr	pointer on string beginning
eol	pointer on character after end of string
str	target string

Return values

FALSE	OK
TRUE	error

my_bool rename_in_schema_file	(	THD *	thd,
		const char *	schema,
		const char *	old_name,
		const char *	new_db,
		const char *	new_name
	)

Renames a frm file (including backups) in same schema.

thread handler

Parameters

schema	name of given schema
old_name	original file name
new_db	new schema
new_name	new file name

Return values

0	OK
1	Error (only if renaming of frm failed)

Definition at line 317 of file parse_file.cc.

my_bool sql_create_definition_file	(	const LEX_STRING *	dir,
		const LEX_STRING *	file_name,
		const LEX_STRING *	type,
		uchar *	base,
		File_option *	parameters
	)

Write new .frm.

Parameters

dir	directory where put .frm
file_name	.frm file name
type	.frm type string (VIEW, TABLE)
base	base address for parameter reading (structure like TABLE)
parameters	parameters description

Return values

FALSE	OK
TRUE	error

Here is the caller graph for this function:

File_parser* sql_parse_prepare	(	const LEX_STRING *	file_name,
		MEM_ROOT *	mem_root,
		bool	bad_format_errors
	)

Prepare frm to parse (read to memory).

Parameters

file_name	path & filename to .frm file
mem_root	MEM_ROOT for buffer allocation
bad_format_errors	send errors on bad content

Note

returned pointer + 1 will be type of .frm

Returns

0 - error
