* Refactor all the 'H5VL_*_optional' callbacks to move the type of operation outQuincey Koziol2020-05-201-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Checkin of fix for CGNS bugmainzer2017-04-061-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (https://jira.hdfgroup.org/browse/HDFFV-10055). Briefly, in H5C_collective_write() in H5Cmpio.c, the metadata cache attempts to perform a collective write of metadata cache entries. This worked fine as long as all processes had at least one entry to write. However, when the process has no entries, the function tries to participate in the collective write by calling MPI_File_set_view(), MPI_File_write_all() and then MPI_File_set_view() again, to match the calls in H5FD_mpio_write(). After pull request 183, the CGNS test benchmark_hdf5 started failing. On investigation, I determined that the failure occurred in the first call to MPI_File_set_view() in the "no data to write" path through H5C_collective_write(). Note that pull request 183 did not create the problem, it only exposed it. The bug can be observed after pull request 182 if one executes the CGNS progam src/ptests/benchmark_hdf5 with 90 processes. The problem appears to have been that the calls to MPI_File_set_view() in H5C_collective_write() and H5FD_mpio_write() were using different values for the info parameter. I patched the problem by adding a MPI specific VFD call allowing me to get the MPI_Info used in H5FD_mpio_write() for use in MPI_File_set_view() calls in H5C_collective_write(). Tested serial & parallel, debug & production on Jelly.

| | | | | | | | | | | | | | | | | | | | checks from metadata dxpls - remove H5AC_ind_dxpl_id and use only H5AC_dxpl_id everywhere instead. - remove flush_me_collectively flag from cache entries - add a collective sanity check (MPI_Barrier) for every HDF5 API routine that could possibly touch the file. This is trigerred when the environment variable H5_COLL_API_SANITY_CHECK is set to a non 0 digit. tested on BB-8 with serial and parallel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Complete revamp of package initialization/shutdown mechanism in the library. Each package now has a single init/term routine. This new way should avoid packages being re-initialized during library shutdown and is also be _much_ more proactive about giving feedback for resource leaks internal to the library. Introduces a new "module" header file for packages in the library (e.g src/H5Fmodule.h) which sets up some necessary package configuration macros for the FUNC_ENTER/LEAVE macros. (The VFL drivers have their own slightly modified version of this header, src/H5FDdrvr_module.h) Also cleaned up a bunch of resources leaks all across the library and tests, along with addressing many warnings, as I encountered them.
