DBI::Gofer::Execute - Executes Gofer requests and returns Gofer responses
$executor = DBI::Gofer::Execute->new( { ...config... });
$response = $executor->execute_request( $request );
Accepts a DBI::Gofer::Request object, executes the requested DBI method calls, and returns a DBI::Gofer::Response object.
Any error, including any internal 'fatal' errors are caught and converted into a DBI::Gofer::Response object.
This module is usually invoked by a 'server-side' Gofer transport module. They usually have names in the "DBI::Gofer::Transport::*" namespace. Examples include: DBI::Gofer::Transport::stream and DBI::Gofer::Transport::mod_perl.
If defined, it must be a reference to a subroutine that will 'check' the request.
The subroutine can either return the original request object or die with a suitable error message (which will be turned into a Gofer response).
It can also construct and return a new request that should be executed instead of the original request.
If set, this DSN is always used instead of the one in the request.
If set, this DSN is used if forced_connect_dsn is not set and the request does not contain a DSN itself.
A reference to a hash of connect() attributes. Individual attributes in forced_connect_attributes will take precedence over corresponding attributes in the request.
A reference to a hash of connect() attributes. Individual attributes in the request take precedence over corresponding attributes in default_connect_attributes.
If set, the loaded drivers will be checked to ensure they don't have more than this number of cached connections. There is no default value. This limit is not enforced for every request.
If set, all the cached statement handles will be cleared once the number of cached statement handles rises above this limit. The default is 1000.
If true, then only the first result set will be fetched and returned in the response.
If set, specifies the number of recent requests and responses that should be kept by the update_stats() method for diagnostics. See DBI::Gofer::Transport::mod_perl.
Note that this setting can significantly increase memory use. Use with caution.
