* Fix shutdown errors when using the HDF5_VOL_CONNECTOR environmentDana Robinson2020-03-181-0/+12
| | | | | variable to set a dynamically loaded plugin as the default VOL connector. Fixes HDFFV-11057
* Reduce differences between my -Werror branch and `develop`:David Young2020-01-291-5/+7
| | | | | | | | Rename index -> idx, fileno -> fnumber, fileno -> fno to avoid GCC shadowed declaration warnings about index(3). Convert #pragma GCC diagnostic push/pop/ignored to the HDF5 library's H5_GCC_DIAG_OFF()/H5_GCC_DIAG_ON() macros.

* Refactor all the 'H5VL_*_optional' callbacks to move the type of operation outQuincey Koziol2019-12-201-135/+263
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Implement H5VLget_file_type() to return a copy of a datatype with theNeil Fortner2019-11-081-2/+2
| | | | | | | | | | | 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.
* Fix H5VL_blob_get to return size of blobJerome Soumagne2019-10-081-3/+89
| | | | | | | | | | | | | | | | | | | | Fix const in blob API Add H5HG_HEAP_ID_SIZE macro to return native blob size Add maximum size for blobs Fix blob API callbacks to pass VOL file object Add public wrappers for blob VOL API Implement passthrough blob callbacks Update H5Tvlen after callback changes Update trace information for H5VL blob routines Fix public header inclusion in native and passthru headers
* Add 'blob' callbacks to VOL, along with a native implementation to store themQuincey Koziol2019-10-081-4/+10

* Merge branch 'develop' into vol_dev_headersDana Robinson2019-06-141-1/+1
|\ | | | | | | | | Also moved the wrapper functions from the H5VLconnector.h to H5VLconnector_passthru.h
| * Added H5Fdelete call and VOL support (but no VFD/native implementation).Dana Robinson2019-06-111-1/+1

* | Split VOL connector routines into separate headers:Dana Robinson2019-05-241-1/+5
|/ | | | | | | | | * H5VLconnector.h for terminal connector things * H5VLconnector_passthru.h for passthrough connector things Note that these headers are arranged such that they are included in hdf5.h so VOL connectors only need to include that. The separation into multiple headers is mainly for readability.

* Add an 'unwrap' VOL callback, so that connectors can unwrap an underlyingQuincey Koziol2019-04-211-7/+60

* Specify the default VOL connector to use with an environment variable.Quincey Koziol2019-03-101-4/+32
| | | | | | | | This implicitly adds support for changing the VOL connector for command-line tools or any application linked with the library. Also, add 'make check-vol' support for all directories, clearing up necessary issues in testing scripts, etc.
* Revise "management" VOL callbacks into 'info' and object 'wrap / retrieval'Quincey Koziol2019-02-231-62/+70

* Add ID type (of eventual hid_t) to the VOL "wrap" callback.Quincey Koziol2019-02-071-3/+4

* Corrected comment in src/H5VLint.c, fixed pass-through info size inQuincey Koziol2019-01-061-1/+2
| | | | | | | src/H5VLpassthru.c, switched to stashing VOL connector ID & info in API context (in src/H5CX.c, src/H5CXprivate.h, src/H5F.c, src/H5Fint.c, and src/H5Fefc.c), patched up all sorts of issues in the tests, to make them work with 'check-vfd' (and 'check-vol' again).
