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.

* [svn-r19682] Bug 2054: Round Robin code caused H5FFlush to corrupt a file.Albert Cheng2010-10-281-0/+2
| | | | | | | | | John Mainzer fixed the bug and added a test which wrote file and flush a few time; close the file then open it by serial and read simple structure. I changed the test to two parallel running parts of ..._writer and ..._reader and have the reader verify the file after every flush by the writer. Tested: parallel in Jam and Amani.
* [svn-r19622] Port of fix for the round robin parallel flush bug caused by ↵John Mainzer2010-10-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | the failure of the H5Ocache.c code to update its image of the on disk representation of the object header on a call to the clear callback. This wasn't an issue as long as all flushes of the object header were made from the same process, but if an object header is modified, and then flushed on one process and cleared on the rest, the changes were not be reflected in the images of the on disk representation on all processes where the object header was cleared rather than flushed. If one of these processes did the next flush, the changes were lost in the on disk representation. Fixed this by causing all dirty messages and to be written to the copy of the on disk image maintained by the object header code on both flush and clear. Also added associated test code in t_mdset.c. Also checking in some cache debug code developed while chasing this bug. Commit tested and tested (parallel) on phoenix.

| | | | | | | | Clean up a few remaining API compatibility issues in the H5E API for parallel configurations Tested on: FreeBSD/64 6.2 (liberty) w/parallel
* [svn-r14096] There're 3 changes in this checkin as below:Raymond Lu2007-08-201-0/+1
| | | | | | | | | | | | | | | | | | 1. In H5Dwrite and H5Dread, let the data buffer point to a fake address if the application passes in an empty buffer. This is mainly for MPIO programs that some processes may not have any data to write or read but still participate the I/O. This solution solves some MPI's problem like the ChaMPIon on tungsten which doesn't support empty buffer. 2. The ChaMPIon on tungsten doesn't support complex derived MPI data type correctly and collective I/O when some processes don't have any data to write or read correctly. Detect the compiler "cmpicc" in the system-specific config file and set the variables for these two cases to false. The PHDF5 library already has set up a way to switch collective chunked I/O to independent under these two cases. 3. A bug fix - During the work of the optimization for compound data I/O, the case for switching collective chunked I/O to independent I/O was leftout. Fixed it by adding I/O caching to it in H5D_multi_chunk_collective_io in H5Dmpio.c. Tested on tungsten, cobalt, and kagiso for parallel; on linew and smirom for serial.

* [svn-r12174] Purpose:MuQun Yang2006-03-291-1/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding parallel tests for optional collective chunk APIs Description: Three new APIs "H5Pset_dxpl_mpio_chunk_opt_ratio H5Pset_dxpl_mpio_chunk_opt_num H5Pset_dxpl_mpio_chunk_opt" for optional optimization choices from users have been added to the libraries. This check-in adds six tests to verify the funcationality and correctedness of these APIs. These tests need to be verified with 3 or more processors and with MPI-IO driver only. Solution: Using H5Pinsert, H5Pget, H5Pset to verify that the library indeed goes into the branch we hope for. Using H5_HAVE_INSTRUMENT macro to isolate these changes so that it won't affect or be misused by the application. Platforms tested: h5committest(shanti still refused to be connected) Parallel tests on heping somehow are skipped. Manually testing at heping. Have checked 1,2,3,4,5 processes. Misc. update:
* [svn-r12148] Purpose:MuQun Yang2006-03-231-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Add tests for optional APIs to support collective chunk IO Description: In order to test whether library picks up the user's options, The number of chunks need to be varied for different processes, Selection of the number of processes selected in one chunk also need to be varied. Solution: Create two cases, 1. Each chunk only selected by one unique process, this case library should use independent for collective call. 2. One-third of the processes occupies the top half of the whole domain, The rest of the processes occupies the lower half of the domain. The total number of chunk is a fixed number 8. Platforms tested: Linux 2.4 with mpich 1.2.6(only) Since I only checked in the code that handles the selection, haven't added any new tests yet. So it won't affect any platforms. Misc. update:

Description: Previously array size for collective optimization tests including cchunk1, cchunk2, cchunk3, cchunk4, ccontw, ccontr, cschunkw, cschunkr, ccchunkw, ccchunkr are fixed, They are only valid for some good number of processors(1,2,3,4,6,8,12,16,24,32,48 etc). Recently there are more requests for parallel tests to be valid on some odd number of processes such as 5,7,11,13 etc. Solution: I change the array size to be dynamic rather than static. Now the fastest change array size is a function of mpi_size. dim2 = constant *mpi_size. After some tunings, theoretically the above tests should be valid for any number of processors. However, other parallel tests still need to be tuned. To verify the correctness of these tests, using mpirun -np 5 ./testphdf5 -b cchunk1 at heping. Platforms tested: h5committest(shanti is refused to be connected) at heping, 5 and 7 processes are used to verify the correctness. Misc. update:

| | | | | | | | | | | | | | | | Enhance collective chunk IO supports Description: Add a new test to check the correctness of the HDF5 library behavior for collective IO mode when one process doesn't have any contribution for IO. Solution: Platforms tested: IBM AIX 5.2(copper) Linux (heping) mpich-1.2.6 Misc. update:
* [svn-r11312] Purpose:Albert Cheng2005-08-301-0/+1
| | | | | | | | | | | | | | | | | | Bug #281 Description: A dataset created in serial mode with H5D_ALLOC_TIME_INCR allocation setting was not extendible, either explicitly by H5Dextend or implicitly by writing to unallocated chunks. This was because parallel mode expects the allocation mode be H5D_ALLOC_TIME_INCR only. Solution: Modified library to allocate more space when needed or directed if the file is opened by parallel mode, independent of what the dataset allocation mode is. Platforms tested: Heping pp.

| | | | | | | | | | | | | | | | | | | | Code cleanup Description: Trim trailing whitespace, which is making 'diff'ing the two branches difficult. Solution: Ran this script in each directory: foreach f (*.[ch] *.cpp) sed 's/[[:blank:]]*$//' $f > sed.out && mv sed.out $f end Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
* [svn-r11067] Purpose:MuQun Yang2005-07-121-12/+12
| | | | | | | | | | | | | | | | | | Updating phase 2 work of collective IO Description: The current collective IO tests cannot test for number of processors bigger than some values, this change will lift those restriction. However, the test may be slower. Solution: Platforms tested: linux 2.4, AIX 5.1, Linux 2.4 IA64 and IRIX 6.5 (I haven't tested big number of processors with the restriction of the machine) Misc. update:
* [svn-r10546] Purpose:MuQun Yang2005-04-051-10/+10

* [svn-r10125] Purpose:Albert Cheng2005-03-031-70/+8
| | | | | | | | | | | | | | | Feature--to provide a standalone mode for t_mpi.c so that it can be built outside of PHDF5 environment. Description: Move definitions that are common to all parallel test programs to a new header file called testpar.h. Leave only Parallel HDF5 tests related definitions in testphdf5.h. Platforms tested: heping (pp) and modi4(PP). Copper was down. Misc. update:

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug Fix/Code Cleanup/Doc Cleanup/Optimization/Branch Sync :-) Description: Generally speaking, this is the "signed->unsigned" change to selections. However, in the process of merging code back, things got stickier and stickier until I ended up doing a big "sync the two branches up" operation. So... I brought back all the "infrastructure" fixes from the development branch to the release branch (which I think were actually making some improvement in performance) as well as fixed several bugs which had been fixed in one branch, but not the other. I've also tagged the repository before making this checkin with the label "before_signed_unsigned_changes". Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel & fphdf5 FreeBSD 4.10 (sleipnir) w/threadsafe FreeBSD 4.10 (sleipnir) w/backward compatibility Solaris 2.7 (arabica) w/"purify options" Solaris 2.8 (sol) w/FORTRAN & C++ AIX 5.x (copper) w/parallel & FORTRAN IRIX64 6.5 (modi4) w/FORTRAN Linux 2.4 (heping) w/FORTRAN & C++ Misc. update:

| | | | | | | | | | | | | | | | Adding testing code for collective IO implementation Description: Won't affect testing HDF5 library. Not tested yet, only check in for debugging purpose. Solution: Platforms tested: Linux 2.4 + mpich 1.2.6 Aix 5.1 + mpcc_r Misc. update:
* [svn-r9520] Purpose:MuQun Yang2004-11-111-0/+16
| | | | | | | | | | | | | | | | | | Adding general MPI derived datatype testing code. Description: The testing code will not be tested. The purpose of checking in is for better debugging later. HDF5 routine or daily test should not be aware of this. Solution: Platforms tested: Copper(AIX 5.1), Heping(Linux 2.4 + MPICH 1.2.6). Misc. update:
* [svn-r9358] Purpose:Quincey Koziol2004-10-041-1/+4
| | | | | | | | | | | | | | | Bug fix Description: Relax restrictions on parallel I/O to allow compressed, chunked datasets to be read in parallel (collective access will be degraded to independent access, but will retrieve the information still).
