This is a work in progress. It's good enough to run `many_dsets`. * Committing clang-format changes * Add the `many_dsets` benchmark and some scripts I used on jelly for setting up the build/test environment and for recording/flame-graphing profiles. * Committing clang-format changes * Change my Makefile and environment script to work both on jelly and on mayll (and probably on Summit). * Disable clang-format "fix." * Replace the `if (!H5_TERM_GLOBAL)` test in each FUNC_ENTER_ macro with `if (true)`. * Fix bad grammar in a comment. * Instead of labeling the H5*__init_package routines constructors, fold each into an initialization routine, H5*_init(), and call each of the H5*_init() routines. Call most of the H5*_init() routines from H5_init_library() in an explicit order that I found out earlier by instrumenting each __init_package routine and running the library tests. Roll H5FD*__init_package routines into H5FD*_init() routines. This change ends just-in-time initialization of package dependencies by package initializers. Don't track in per-package variables (H5_PKG_INIT_VAR) whether each package has been initialized. Instead, track in a single library variable whether the whole library is initialized or not. Drive the initialization of packages by H5_init_library() with a table of initializer routines. Also drive the termination of packages by H5_term_library() with a table. Perform initialization as needed from FUNC_ENTER_API_INIT(err). This basically restores the old behavior of that macro. Delete a bunch of #definitions in H5private.h that have fallen out of use with these changes. * Committing clang-format changes * Undo the bad auto-formatting that appears to have occurred in spite of my disabling it. Bracket some code in /* clang-format off */ /* clang-format on */ to prevent a recurrence. * Remove a diagnostic abort(). * Fix a logic error: print a comma between every package terminator run, and don't print an initial comma. * Complete the changes I started in H5_term_library() that undo the bad auto-formatting. Stop tracking whether package "tops" were initialized in per-package variables H5*_top_package_initialize_s. H5_term_library() takes care of that for them. Remove H5R_top_term_package() and H5R_term_package(), they don't do anything. * Committing clang-format changes * NFCI. Simplify macro text: replace `if (true) {` with `{`. * Fix formatting and suppress clang-format on a longer range. * Quiet some unused label, unused variable complaints that cropped up after I simplified the FUNC_ENTER_ macros for the sake of performance. * Committing clang-format changes * Delete some programs and scripts that don't belong in the pull request. * Use the right function-entry macro. * Use a sensible format and disable auto-formatting. * Stop calling do-nothing initializer H5FS_init(). Delete it. * Document what changes to make if the default VFD changes. * While I am here, change an `await_prior` flag on the terminator table to `true` to match the previous, non-table-driven code that was here. Found the oversight making the following changes: NFCI: insert an empty line and copy over slightly-edited comments from the previous version, where those comments still correctly explained how library termination operated. * NFCI: lower a staircase. * Replace every occurrence of FUNC_ENTER_NOAPI_INIT(...) with H5_PUSH_FUNC since that is all that that macro does any more. Quiet a bunch of new warnings by changing FUNC_ENTER_NOAPI(...) to FUNC_ENTER_NOAPI_NOERR and removing disused `done:` labels. * NFCI: add curly braces around a multiline statement. * Quiet a signed/unsigned comparison warning. * Add some documentation about library initialization and shutdown. * Make sure that the library is initialized, or else that initialization is already underway, before performing any VFD's initialization. * Committing clang-format changes * Committing clang-format changes * Reduce differences from `develop` branch. * Always initialize `tot_init`. * Committing clang-format changes * Fix typo: H5SL_init initializes skip lists, not VOL. * Remove H5_TERM_GLOBAL test in H5T_init. H5T_init was unusual in that it tested H5_TERM_GLOBAL and exited early if it was set. No other module initializers did that, and I cannot find any reason that should be necessary. Tests still pass when I remove it, so away it goes. * Use HD prefix. * Add function header comments. * Drop the intermediate variable, it's only used once. * Extract subroutine `H5FDperform_init(hid_t (*init)(void))` that initializes the library, if necessary, before calling its VFD-initializer argument. Use H5FDperform_init in the definition of the symbols H5FD_<vfd> (e.g., H5FD_SEC2), which may be evaluated before the library is initialized, like so: ``` ``` I implement H5FDperform_init in its own source file, H5FDperform.c, and exclude that file from trace processing because the `bin/trace` cannot deal with the function-pointer type. * Straggler from last: add new source file src/H5FDperform.c. * Committing clang-format changes * Add a missing file to the MANIFEST. * Switch to FUNC_ENTER_API_NOINIT in H5FDperform_init() and hbool_t in H5_term_library().

* VFD plugins (#602)jhendersonHDF2021-09-291-11/+52
| | | | | | | | | | | | | | | | | * Implement support for loading of Virtual File Drivers as plugins Fix plugin caching for VOL connector and VFD plugins Fix plugin iteration to skip paths that can't be opened * Enable dynamic loading of VFDs with HDF5_DRIVER environment variable * Temporarily disable error reporting during H5F_open double file open * Default to using HDstat in h5_get_file_size for unknown VFDs * Use macros for some environment variables that HDF5 interprets * Update "null" and "ctl testing" VFDs
* VFD ctl feature (#981)jhendersonHDF2021-09-231-117/+106
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Added "ctl" callback to the VFD interface, and the associated H5FDctl() and H5FD_ctl() calls. Modified the MPIO VFD accordingly -- specifically: Added ctl() call with op-code support to expose rank, size, and communicator. Modified H5FD_mpi_get_rank(), H5FD_mpi_get_size(), and H5FD_mpi_get_comm() to use the new ctl() callback. In passing removed the const qualifier from the file parameter of these functions, as the file parameter of the ctl callback is not const. Deleted the old H5FD__mpio_mpi_rank(), H5FD__mpio_mpi_size(), and H5FD__mpio_communicator() calls from the MPIO VFD. Deleted H5FD_class_mpi_t from H5FDprivate.h, and modified the MPIO VFD accordingly. Note that all VFDs now use H5FD_class_t, with no special class for VFDs that that support MPI. Some minor touch ups to the Neil's selection I/O mods in passing. Tested serial and parallel, debug and production on charis and jelly. * Reserve a range of VFD "ctl" opcodes for library and experimental usage * Add "ctl" callbacks to passthrough VFDs * Add RELEASE.txt entry for "ctl" callback * Use H5FDopen with H5F_ACC_RDWR flag instead of H5F_ACC_TRUNC in vfd test * Remove handling of passthrough "ctl" flag from multi VFD * Move logic for testing H5FD_CTL__TEST_OPCODE into a testing VFD Revise description of "ctl" callback in RELEASE.txt Remove unused H5FD_CTL__NUM_OPCODES definition Fix some warnings in multi VFD Co-authored-by: mainzer <mainzer#hdfgroup.org>

* Checkin of fix for CGNS bugmainzer2017-04-061-1/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (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.
