Detailed Description

Checks if path specified to load is contained in plug-in directory and change it to absolute one using plug-in directory.

Calls wrapped file scheme service implementation on calculated absolute URN. Effectively it act as a filtering and mapping service.

check_and_make_absolute_urn()

bool mysql_dynamic_loader_scheme_file_path_filter_imp::check_and_make_absolute_urn ( const char *  input_urn, std::string &  out_path  )

staticprivate

Ensure that the dynamic library doesn't have a path.

This is done to ensure that only approved libraries from the plug-in directory are used (to make this even remotely secure). Extracts real absolute path to file in plug-in directory.

Parameters

	input_urn	URN with path to validate and make absolute.
[out]	out_path	String to put result URN to.

load()

mysql_service_status_t mysql_dynamic_loader_scheme_file_path_filter_imp::load ( const char *  urn, mysql_component_t **  out_data  )

staticnoexcept

Checks if path specified to load is contained in plug-in directory and change it to absolute one using plug-in directory.

Calls wrapped file scheme service implementation on calculated absolute URN.

Parameters

	urn	URN to file to load components from.
[out]	out_data	Pointer to pointer to MySQL component data structures to set result components data retrieved from specified file.

Returns

Status of performed operation

Return values

false	success
true	failure

unload()

mysql_service_status_t mysql_dynamic_loader_scheme_file_path_filter_imp::unload ( const char *  urn )

staticnoexcept

Checks if path specified to load is contained in plug-in directory and change it to absolute one using plug-in directory.

Calls wrapped file scheme service implementation on calculated absolute URN.

Parameters

urn	URN to file to unload all components from.

Returns

Status of performed operation

Return values

false	success
true	failure
