Bring async branch to develop (#166) * Add H5Fwait, H5Dwait, and other changes for async vol connector * Revert temporary testing changes * Add H5Fwait to header file * Add H5VLreset_lib_state() routine. * Correct VOL wrap context when retrieving library state for file open & create. * Manage the API context's VOL connector state as part of the library state. * Set the 'VOL connector property valid' flag when restoring the library state. * Don't push new API context on stack when retrieving "current" one. * Check for NULL VOL wrap context before decrementing refcount on it, when freeing the API context state. * Manage recount of underlying connector for VOL wrap context. * Add H5TSmutex_acquire() and H5TSmutex_release() routines to acquire and release the global lock on the HDF5 library. * Update library with new functions related to library global lock * Add asynchronous token API * Add new lightweight FUNC_ENTER / LEAVE macros for helping to structure the threadsafety (H5TS*) routines. * Sync w/develop * Initial event set code framework. * Elaborate on the H5ES routines, starting to add API routines. Update the "close ID" callbacks to allow asynchronous request tokens to be passed in from an asynchronous close API call. Refactor current asynchronous API routines (H5Fopen/H5Fclose and H5Dread/H5Dread) to use event sets instead of directly working with request tokens from the application. Clean up a few other minor warnings & code style issues. * Implement H5EScreate, H5ESget_count, and H5ESclose. It should be possible to write a simple application that creates an event set and uses it with H5Fopen_async, H5Dread_async, H5Dwrite_async, and H5Fclose_async, then calls H5ESclose (which waits for all async events to complete). * Add source file for event set test. * Refactor sync & async API routines to call common routine. Move dataset API read / write routines to src/H5D.c, along with all the other API routines. Progress on "fake" async VOL connector, for testing. * Modify async implementation to wrap async requests in a H5VL_object_t struct so the VOL layer can find the connector when accessing the request at a later point. * Free the requests is H5ESclose. Remove comments implying that request wait, notify, and cancel callbacks should free the request. * Fix bug in error handling in H5Fclose. * Fix bugs in async file routines. Rename H5VL_create_object_generic to H5VL_create_object. * Add explicit async version of H5Fcreate. * Add more _async routines * Correct typo for return value from H5Awrite changes * Add H5EStest and H5ESwait routines * Updated with API tracing info * Fix NULL pointer dereference in H5ES__wait * Add H5is_library_terminating() routine, so that VOL connectors can detect when the library is shutting down. * Fix typo * Remove event from event set's linked list * Move block of code so that vol_obj is valid * Avoid setting properties in the DXPL when reseting the library state (and in the test code). * Refactor argument tracing to implement new capability for tracing arguments of non-API routines, with the H5ARG_TRACE macro. This macro is updated automatically with the bin/trace script that runs as part of the autogen.sh process. Major changes were in src/H5trace.c and bin/trace, with the other changes being cleanups to the argument lists, to improve their presentation in the tracing output. Also - added the "managed string" routines, which can dynamically allocate strings, appending printf-formatted output to the string efficiently. * Release memory for managed strings * Fix printf() formats. * More printf() format fixes. * Add H5Eappend_stack routine and regression tests * Clean up a few missed merge conflicts and update the error stacks. * Remove unnecessary fork() operations and ten second sleep(). * Restore commented out attribute out, to better enable tracking down the previous failure * Allow multiple H5ARG_TRACE macros within a routine to be updated * Switch to using "new" H5ES_insert (which takes the arguments for the caller routine) for all event set operations. Renames H5ES_insert_new to H5ES_insert and removes the previous H5ES_insert. * Merge "managed" string routines into "ref-counted" strings, and refactor code to use them. * Add missing file. * Add caller's name and arguments to event, for error reporting * Refactor event set setup for "API common" internal routines * Checkin async API routines for H5A* and H5G* modules as listed in ID-283. Fix couple h5dump expected output files due to the changes. * Add some of the error query routines needed for event sets. * Refactor to make async setup / teardown and "common" routines cleaner * (1) Add async APIs to H5L, H5F, and H5D modules (2) Fix errors in previous checkins of async APIs in H5A and H5G modules (3) h5dump expected output changes * Enhance event info, for better error handling * Change name of temporary vol_obj variable, to help reduce coding errors * Fix oversight with vol_obj pointer * Minor code cleanup * Add missing \'valid\' flag for VOL wrapper context, when restoring the library\'s state * Run source formatter * Change H5TSmutex lock and release to include a lock count * Update error reporting ideas * Minor updates to improve sanity checking for retrieving / restoring library state * Updated with feedback from h5py team members * Refactor internal event set list and event handling, add implementation for H5ESget_err_info * Change the VOL request subclass callbacks that switch from using "H5ES_status_t" to "H5VL_request_status_t", and also add a H5VL_request_status_t* parameter to the 'cancel' callback in the request subclass. Also more code quality cleanups to add iterator callbacks to internal event set routines. * Update API tracing for new H5VL_request_status_t typedef * Finish converting internal event set operations to use list iterator callbacks, instead of directly accessing the list structure * Add H5VL_REQUEST_GET_ERR_STACK operation to request subclass, for retrieving a copy of the error stack for a failed asynchronous operation * Remove 'canceled' event status from Java constants * Be safer about releasing resources when inserting a newly opened/created object or file into an event set * Remove H5EStest, add H5ES_WAIT_NONE for 0 timeout, and revise parameters to H5ESwait, to make it more "aggregate". * Remove H5ES_STATUS_CANCELED from Java wrappers also * (a) Add async APIs for H5O module as listed in jira issue ID-283. (b) Remove verification of name parameter in async related routines for H55A and H5L modules because it is checked in H5VL_setup* routine. (c) Modify h5dump expected output due to the async changes. * Corrections based on PR feedback. * Further changes to make based on PR feedback. * Fix missed merge marker, and reformatted line * Clean up some warnings * Correct level of indirection * Relocate prototype (and doxygen info) for H5Aclose * Change non-static function declarations to be static * Ensure that H5TSpublic.h header gets installed (#129) * Add 'wrapper' versions of async calls, to allow language wrappers and layers on top of HDF5 to pass in their application information. * Switch H5Aexists\*_async and H5Lexists\*_async to use flag to return status, instead of return value. Make the corresponding changes through most of the v1 and v2 B-tree code. Clean up warnings in H5public.h and cmpd_dtransform.c. * Add H5Iregister_future routine and tests. * Correct return value for H5Lexists_async * Add H5_DLL macro to public H5ES API routines * Update supported -> flags parameter for introspect_query callback * Remove my email address. Update passthrough VOL connector ID. * Fix comment for post_open_api_common * Remove unused non-blocking VOL connector * Minor cleanup in async branch in preparation for merge to develop * Update CMake and the Autotools to use the new pass-through VOL ID * Fix for SWMR daily test failures (#160) The H5I_register_using_existing_id() call did not initialize the future ID callbacks, causing the library to segfault when it tried to resolve those function pointers. * Added selective async APIs (#150) * Added selective async APIs Description: Added the following APIs: H5Ropen_attr_async H5Ropen_object_async H5Ropen_region_async H5Mcreate_async H5Mopen_async H5Mput_async H5Mget_async H5Mclose_async H5Tcommit_async H5Topen_async H5Tcopy_async H5Tclose_async - Updated an expected output file to include a new internal function in the error stack for the failure case. * Updated async APIs per reviews, including removing async version of H5Tcopy. * Removed statements that were added by mistake in the previous commit. * Fix compile issues in H5M and warnings elsewhere * Reformat code * Brings VOL_LIST changes from develop.

And, corrected logic error in test/links.c around non-existant objects in a file. * Convert request VOL class 'specific' operations to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs. * Convert blob VOL class 'specific' operations to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs. Also removes the H5VL_BLOB_GETSIZE operation, as it's unused in the library and the blob ID size for a container is now returned with H5VL_FILE_GET_CONT_INFO. * Add 'const' to several parameters that are only queried. * Convert all VOL classes' 'optional' operations to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs. Convert several 'get' routines to return the length of an array in a parameter instead of combining it into the return value. Move several routines to be in less public namespace. Correct direct_chunk test to verify that parameters aren't modified on error. * Switch get/specific/optional VOL callback argument structures to be 'async-friendly'. Also other minor cleanups and bug-fixes. * Add H5Pset_dataset_io_hyperslab_selection / H5S_PLIST feature, to allow skipping H5Dget_space + H5Sselect_hyperslab for async operation * Add dynamic optional operations for request objects * Update dynamic operation test for optional request operations * Update a comment for an operation argument * Run trace and format_source scripts * Committing clang-format changes * Committing clang-format changes Co-authored-by: vchoi <vchoi@jelly.ad.hdfgroup.org> Co-authored-by: vchoi-hdfgroup <55293060+vchoi-hdfgroup@users.noreply.github.com> Co-authored-by: jhendersonHDF <jhenderson@hdfgroup.org> Co-authored-by: Dana Robinson <derobins@hdfgroup.org> Co-authored-by: Dana Robinson <43805+derobins@users.noreply.github.com> Co-authored-by: bmribler <39579120+bmribler@users.noreply.github.com> Co-authored-by: github-actions <41898282+github-actions[bot]@users.noreply.github.com>

#include "H5ESpublic.h"
#include "H5ESdevelop.h"
Bring async branch to develop (#166) * Add H5Fwait, H5Dwait, and other changes for async vol connector * Revert temporary testing changes * Add H5Fwait to header file * Add H5VLreset_lib_state() routine. * Correct VOL wrap context when retrieving library state for file open & create. * Manage the API context's VOL connector state as part of the library state. * Set the 'VOL connector property valid' flag when restoring the library state. * Don't push new API context on stack when retrieving "current" one. * Check for NULL VOL wrap context before decrementing refcount on it, when freeing the API context state. * Manage recount of underlying connector for VOL wrap context. * Add H5TSmutex_acquire() and H5TSmutex_release() routines to acquire and release the global lock on the HDF5 library. * Update library with new functions related to library global lock * Add asynchronous token API * Add new lightweight FUNC_ENTER / LEAVE macros for helping to structure the threadsafety (H5TS*) routines. * Sync w/develop * Initial event set code framework. * Elaborate on the H5ES routines, starting to add API routines. Update the "close ID" callbacks to allow asynchronous request tokens to be passed in from an asynchronous close API call. Refactor current asynchronous API routines (H5Fopen/H5Fclose and H5Dread/H5Dread) to use event sets instead of directly working with request tokens from the application. Clean up a few other minor warnings & code style issues. * Implement H5EScreate, H5ESget_count, and H5ESclose. It should be possible to write a simple application that creates an event set and uses it with H5Fopen_async, H5Dread_async, H5Dwrite_async, and H5Fclose_async, then calls H5ESclose (which waits for all async events to complete). * Add source file for event set test. * Refactor sync & async API routines to call common routine. Move dataset API read / write routines to src/H5D.c, along with all the other API routines. Progress on "fake" async VOL connector, for testing. * Modify async implementation to wrap async requests in a H5VL_object_t struct so the VOL layer can find the connector when accessing the request at a later point. * Free the requests is H5ESclose. Remove comments implying that request wait, notify, and cancel callbacks should free the request. * Fix bug in error handling in H5Fclose. * Fix bugs in async file routines. Rename H5VL_create_object_generic to H5VL_create_object. * Add explicit async version of H5Fcreate. * Add more _async routines * Correct typo for return value from H5Awrite changes * Add H5EStest and H5ESwait routines * Updated with API tracing info * Fix NULL pointer dereference in H5ES__wait * Add H5is_library_terminating() routine, so that VOL connectors can detect when the library is shutting down. * Fix typo * Remove event from event set's linked list * Move block of code so that vol_obj is valid * Avoid setting properties in the DXPL when reseting the library state (and in the test code). * Refactor argument tracing to implement new capability for tracing arguments of non-API routines, with the H5ARG_TRACE macro. This macro is updated automatically with the bin/trace script that runs as part of the autogen.sh process. Major changes were in src/H5trace.c and bin/trace, with the other changes being cleanups to the argument lists, to improve their presentation in the tracing output. Also - added the "managed string" routines, which can dynamically allocate strings, appending printf-formatted output to the string efficiently. * Release memory for managed strings * Fix printf() formats. * More printf() format fixes. * Add H5Eappend_stack routine and regression tests * Clean up a few missed merge conflicts and update the error stacks. * Remove unnecessary fork() operations and ten second sleep(). * Restore commented out attribute out, to better enable tracking down the previous failure * Allow multiple H5ARG_TRACE macros within a routine to be updated * Switch to using "new" H5ES_insert (which takes the arguments for the caller routine) for all event set operations. Renames H5ES_insert_new to H5ES_insert and removes the previous H5ES_insert. * Merge "managed" string routines into "ref-counted" strings, and refactor code to use them. * Add missing file. * Add caller's name and arguments to event, for error reporting * Refactor event set setup for "API common" internal routines * Checkin async API routines for H5A* and H5G* modules as listed in ID-283. Fix couple h5dump expected output files due to the changes. * Add some of the error query routines needed for event sets. * Refactor to make async setup / teardown and "common" routines cleaner * (1) Add async APIs to H5L, H5F, and H5D modules (2) Fix errors in previous checkins of async APIs in H5A and H5G modules (3) h5dump expected output changes * Enhance event info, for better error handling * Change name of temporary vol_obj variable, to help reduce coding errors * Fix oversight with vol_obj pointer * Minor code cleanup * Add missing \'valid\' flag for VOL wrapper context, when restoring the library\'s state * Run source formatter * Change H5TSmutex lock and release to include a lock count * Update error reporting ideas * Minor updates to improve sanity checking for retrieving / restoring library state * Updated with feedback from h5py team members * Refactor internal event set list and event handling, add implementation for H5ESget_err_info * Change the VOL request subclass callbacks that switch from using "H5ES_status_t" to "H5VL_request_status_t", and also add a H5VL_request_status_t* parameter to the 'cancel' callback in the request subclass. Also more code quality cleanups to add iterator callbacks to internal event set routines. * Update API tracing for new H5VL_request_status_t typedef * Finish converting internal event set operations to use list iterator callbacks, instead of directly accessing the list structure * Add H5VL_REQUEST_GET_ERR_STACK operation to request subclass, for retrieving a copy of the error stack for a failed asynchronous operation * Remove 'canceled' event status from Java constants * Be safer about releasing resources when inserting a newly opened/created object or file into an event set * Remove H5EStest, add H5ES_WAIT_NONE for 0 timeout, and revise parameters to H5ESwait, to make it more "aggregate". * Remove H5ES_STATUS_CANCELED from Java wrappers also * (a) Add async APIs for H5O module as listed in jira issue ID-283. (b) Remove verification of name parameter in async related routines for H55A and H5L modules because it is checked in H5VL_setup* routine. (c) Modify h5dump expected output due to the async changes. * Corrections based on PR feedback. * Further changes to make based on PR feedback. * Fix missed merge marker, and reformatted line * Clean up some warnings * Correct level of indirection * Relocate prototype (and doxygen info) for H5Aclose * Change non-static function declarations to be static * Ensure that H5TSpublic.h header gets installed (#129) * Add 'wrapper' versions of async calls, to allow language wrappers and layers on top of HDF5 to pass in their application information. * Switch H5Aexists\*_async and H5Lexists\*_async to use flag to return status, instead of return value. Make the corresponding changes through most of the v1 and v2 B-tree code. Clean up warnings in H5public.h and cmpd_dtransform.c. * Add H5Iregister_future routine and tests. * Correct return value for H5Lexists_async * Add H5_DLL macro to public H5ES API routines * Update supported -> flags parameter for introspect_query callback * Remove my email address. Update passthrough VOL connector ID. * Fix comment for post_open_api_common * Remove unused non-blocking VOL connector * Minor cleanup in async branch in preparation for merge to develop * Update CMake and the Autotools to use the new pass-through VOL ID * Fix for SWMR daily test failures (#160) The H5I_register_using_existing_id() call did not initialize the future ID callbacks, causing the library to segfault when it tried to resolve those function pointers. * Added selective async APIs (#150) * Added selective async APIs Description: Added the following APIs: H5Ropen_attr_async H5Ropen_object_async H5Ropen_region_async H5Mcreate_async H5Mopen_async H5Mput_async H5Mget_async H5Mclose_async H5Tcommit_async H5Topen_async H5Tcopy_async H5Tclose_async - Updated an expected output file to include a new internal function in the error stack for the failure case. * Updated async APIs per reviews, including removing async version of H5Tcopy. * Removed statements that were added by mistake in the previous commit. * Fix compile issues in H5M and warnings elsewhere * Reformat code * Brings VOL_LIST changes from develop.

Simplify function enter macros for performance benefits (#1024) * Take a stab at using constructors to initialize instead of function-entry macros. 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().
