* Refactor all the 'H5VL_*_optional' callbacks to move the type of operation outQuincey Koziol2019-12-201-16/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | of the va_list, so it's at least possible for another connector to know what the operation is and decide whether to implement it or not. Added a new VOL sub-class called "introspect" where callbacks that report information about the connector or container can be placed. Added an 'opt_query' callback to this sub-class, for a connector to report back to the library whether a particular optional callback operation is supported. Also added a 'get_conn_cls' introspection callback, to retrieve the H5VL_class_t of a connector (either the "current" connector, H5VL_GET_CONN_LVL_CURR, or the terminal connector, H5VL_GET_CONN_LVL_TERM). Moved the "post open" operation from a file 'specific' operation to a file 'optional' operation, now that it's possible to detect (with the 'opt_query' introspection callback) whether a VOL connector implements an optional operation, without just returning an error. Added new internal VOL helper routines: H5VL_object_is_native, to determine if an object is in (or is a) native file, and H5VL_file_is_same, to determine if two objects are in (or are) the same terminal VOL connector's container. (And moved the special handling for FILE_IS_EQUAL operation out of internal VOL callback routine into H5VL_file_is_same) Made new dataset 'get' operation for H5Dvlen_get_buf_size, aligning it better with other 'get' operations in API. Fixed several issues with pass-through connectors, which are now passing the 'make check-passthrough-vol' tests again. A bunch of warning and style cleanups as well.

| | | | | | | | | | | location set to be in a file. Only meant to be used by VOL connectors. Implement H5VLpeek_connector_id() to support connectors querying their own IDs. Fix app_ref with connector IDs in a couple places (external VOLs registered as default through ENV should be visible to the application). Modify vlen and reference interfaces to work with arbitrary VOL connectors. Implement file "post open" specific callback, to enable connectors to update their file structs after a wrap context has been set.

| * Updates to the VOL ID and object API calls.Dana Robinson2018-10-171-7/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This brings the H5VL code in line with the H5I code regarding naming, parameter order, etc. Several public API calls were affected by this change. These changed names to reflect their use with VOL drivers: H5VLregister() --> H5VLregister_driver() H5VLregister_by_name() --> H5VLregister_driver_by_name() H5VLunregister() --> H5VLunregister_driver() H5VLis_registered() --> H5VLis_driver_registered() This call was renamed to match H5Iregister(). The order of the first two parameters also reversed and the object pointer is now const. H5VLobject_register() --> H5VLregister()
