This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir.

Opening/Closing * @ingroup file_driver * * An XIO handle with the file driver can be created with * @ref globus_xio_handle_create() * * If there is no handle set on the attr passed to the * @ref globus_xio_open() call, it performs the equivalent of an * open() call. In this case, the contact string must contain * either a pathname or one of stdin://, stdout://, or stderr://. If a * pathname is used, that path is opened. If one of the schemes are used * the corresponding stdio handle is used (retrieved with fileno()). * * In either of the above cases, it is most efficient to call the blocking * version of globus_xio_open(). It is also safe to call within a locked * critical section. * * When the XIO handle is closed, the file driver will destroy its internal * resources and close the fd (unless this fd was set on an attr or converted * from one of the stdio handles). */ /** * @defgroup file_driver_io Reading/Writing * @ingroup file_driver * * Both the @ref globus_xio_register_read() and * @ref globus_xio_register_write() calls follow similar semantics as described * below. * * If the waitforbytes parameter is greater than zero, the io will happen * asynchronously and be completed when at least waitforbytes has been * read/written. * * If the waitforbytes parameter is equal to zero, one of the following * alternative behaviors occur: * * If the length of the buffer is > 0 the read or write happens synchronously. * If the user is using one of the blocking xio calls, no internal callback * will occur. * * If the length of the buffer is also 0, the call behaves like an asynchronous * notification of data ready to be either read or written. ie, an * asynchronous select(). * * In any case, when an error or EOF occurs before the waitforbytes request * has been met, the outgoing nbytes is set to the amount of data actually * read/written before the error or EOF occurred. * * You may either use GLOBUS_XIO_FILE_SEEK or GLOBUS_XIO_SEEK to position the * file pointer before each read or write or you can specify the * desired offset on a data descriptor with the xio cmd, * GLOBUS_XIO_DD_SET_OFFSET. simultaneous reading and writing is only * predictable if the data descriptor method is used. */ /** * @defgroup file_driver_envs Env Variables * @ingroup file_driver * * The file driver uses the following environment variables * - GLOBUS_XIO_FILE_DEBUG Available if using a debug build.

Associated with each handle is a stack of drivers. * A driver is a module piece of code that implements the globus_xio * driver interface. The purpose of a driver is manipulate data passed * in by the user in someway. Each driver in a stack will serve its own * unique purpose. * \n * IO operations pass from driver to driver, starting at the top of the * stack and ending at the bottom. When the bottom layer driver finishes * with the operation it signals globus_xio that it has completed. * Completion notification then follows the driver stack up to the top. * * \par Driver Types: * * \par * Transport driver:\n * A transport driver is one that is responsible for actually putting * bytes onto the wire. For example: A TCP driver or a UDP driver would * be an example of transport drivers. * \n\n * Per driver stack there must be exactly one transport driver and * must be at the bottom of the stack. A transform driver is defined * by its lack of passing an operation to the next driver in the stack. * This type of driver does not rely on globus_xio for further completion * of an operation, rather it is self sufficent in this task. * * \par * Transform driver:\n * A tranform driver is any intermediate driver in the stack. These * drivers are indentified by there reliance on the driver stack to * complete the operation. These drivers must pass the operation * down the stack because they cannot complete it themselves. An * example of a transform driver would be a gsi driver. This driver * would wrap and unwrap messages, but would not be able to complete * the transport itself, so it would rely on the remaining drivers in * the stack. * * \par Driver API * The globus xio driver api is a set of functions and interfaces * to allow a developer to create a backend driver for globus_xio. * To create a driver the user must implement all of the interface * functions in the driver specification. * There are also a set of functions provide to assist the driver * author in implemention. * * \par * Quick Start:\n * Four basic driver needs the user will have to pay attention to a * few new structures and concepts. * * \par * globus_xio_operation_t\n * This structure represents a request for an operation. If * the driver can service the operation it does so and the * calls the appropriate finish_operation() function. If the * driver cannot completely service the operation it can pass() * it along to the next driver in the stack. As soon as the * operation structure is either finished or passed it is no * longer valid for use in any other function. * * \par * globus_xio_driver_handle_t\n * A driver_handle represents a open handle to the driver stack for xio. * The driver obtains a driver_handle by calling * globus_xio_driver_open(). * When the open operation completes (it callback is called) the * driver then has a driver_handle. The driver_handle * allows the user to do some * complex things that will be described later. * * \par * globus_xio_stack_t\n * This structure provides the driver with information about the * driver stack It is mainly used for creating driver_handle as a * parameter to lobus_xio_driver_open().. * * \par Typical Sequence: * Here is a typcial sequence of events for a globus_xio transform * driver: * * \par * Open\n * globus_xio_driver_open_t is called. The user calls * globus_xio_driver_open() passing it the operation and * the stack and a callback. When the open callback is called * the driver is given a new operation as a parameter. The driver * will then call globus_xio_driver_finished_open() passing * it the now initialized driver_handle and the newly received * operation. * The call to globus_xio_driver_finished_open() does two things: * 1) it tells globus_xio that this driver has finished its open * operation, and 2) it gives xio the driver_handle (which contains * information on the drivers below it). * * \par * Read/Write\n * The read or write interface funcion is called. It receives * a operation as a parameter. The driver then calls the * approriate pass operation and waits for the callback. When * the callback is received the driver calls finished_operation * passing in the operation structure it received in the callback * * \par * Close\n * The close interface function is called and is passed an * operation and a driver_handle. The driver will call * globus_xio_driver_close() passing it the operation. * When the close callback is received the driver calls * globus_xio_driver_finished_close() passing it the * operation received in the close callback and the driver_handle * received in the interface function. At this point the * driver_handle * is no longer valid.. */ /** * @addtogroup globus_xio_driver * * \par Advanced Driver Programming * The typical driver implementatin is describe above. However globus_xio * allows driver authors to do more advanced things. Some of these things * will be explored here. * * \par * Read Ahead\n * Once a driver_handle is open a driver can spawn operation structures from * it. This gives the driver the ability to request io from the driver * stack before it receives a call to its own interface io interface * function. So if a driver wishes to read ahead it does the following: * * \li it creats an operation by calling globus_xio_driver_create_operation() * and passing it the driver_handle it is intereesting in using. * * \li call globus_xio_driver_read() using this operations. When the read * callback is received the driver may call finished_operation() on the * op it receives (this ultimitely results in very little, since this * operation was started by this driver, but it is good practice and will * free up resources that would otherwise leak). * * \li Now when the user finally does receive a read interface call from * globus_xio it can imediately finish it using the operation it just * received as a parameter and updating the iovec structure to represent * the read that already occured. * * \par * Preopening handles.\n * Once the driver has received a globus_xio_driver_stack_t it can * open a driver_handle. The globus_xio_driver_stack_t comes in the * call to the interface function globus_xio_server/client_init_t(). * The driver uses this structure in a call to globus_xio_driver_open(). * When this functionality completes the driver has an initialized * driver_handle and can use it to create operations as described above. * The driver can now hang onto this driver_handle until it receives an open * interface function call. At which time it can call * globus_xio_driver_finished_open() passing in the driver_handle and thereby * glueing the pre opened driver_handle with the requested globus_xio * operation. */ /** * @defgroup driver_pgm Driver Programming * * The set of interface functions that the driver author must implement * to create a driver and the functions to assist in the creation. * * Driver attribute functions * * If the driver wishes to provide driver specific attributes to the * user it must implement the following functions: * * globus_xio_driver_attr_init_t * globus_xio_driver_attr_copy_t * globus_xio_driver_attr_cntl_t * globus_xio_driver_attr_destroy_t */ /******************************************************************* * callbacks ******************************************************************/ /** * callback interface * @ingroup driver_pgm * * This is the function signature of callbacks for the * globus_xio_driver_open/close(). * * @param op * The operation structure associated with the open or the * close requested operation.
