* Uses TCP/IP sockets.
* Server and auxiliary server-shutdown programs provided in a new directory,
`utils/mirror_vfd`.
* Automated testing via loopback ("remote" of localhost).
objects as the cache_image test does. The zoo writer is a work in
progress.
This version is useful as a reproducer for the hang in the global heap
that I stumbled over, yesterday. I run this to reproduce,
env HLOG="pbio=on" ./vfd_swmr_zoo_writer -W -a

including the merge of `hdffv/hdf5/develop`, back to the branch that Vailin and
I share.
Now I need to put this branch on a fork with a less confusing name than
vchoi_fork!

Description:
- Added functions to query chunk information:
H5Dget_num_chunks(dset_id, fspace_id, *nchunks)
Gets the number of written chunks that intersect with the given
dataspace. However, in this version, the intersection is not
yet completed. Thus, the number of all written chunks will be
returned.
H5Dget_chunk_info_by_coord(dset_id, *offset, *filter_mask, *addr, *size)
Given a chunk's logical coordinates, returns the chunk's filter,
address, and size.
H5Dget_chunk_info(dset_id, fspace_id, index, *offset, *filter_mask, *addr, *size)
Given a chunk's index, returns the chunk's logical coordinates, filter,
address, and size. The chunk belongs to a set of chunks that have
nonempty intersection with the specified dataspace. However, in
this version, the intersection is not yet completed, and the index
is of all the written chunks.
These functions comply with VOL.
- Fixed some oversights found in the library for the tests in chunk_info.c
to work correctly. The returned value from a callback function was not
checked in H5EA_iterate(), H5FA_iterate(), and H5D__none_idx_iterate().
This oversight caused a callback function to continue iterating even though
it's supposed to stop.
Platforms tested:
Linux/64 (jelly)
Linux/64 (platypus)
Darwin (osx1011test)
1. switched to use the existing H5F_prefix_open_t for enum type;
2. put the common private function used by external.c and external_env.c into external_common.c
1. restored the datatype, dataspace, and LCPL of the dataset for VOL connector back to the properties.
2. splitted external.c and vds.c because they called HDsetenv in the program, instead using shell scripts to set the environment variables.
3. changed H5CX_get_vds_prefix and H5CX_get_ext_file_prefix to use H5P_peek instead of H5P_get.
* commit '3ca19cca5395d79be69209f8d7d0a2b06834a648':
Flipped swapped testing strings.
Added test_vol_plugin.sh to the list of scripts to clean
Fixed a CMake build issue (CMake still doesn't run the VOL plugin tests)
Added more sub-tests to the VOL plugin test.
Added a simple test for registration of VOL connector plugins. Autotools only for right now, but this will be fleshed out in future work.
after deleting attributes in densed storage.
The fix: When deleting attribute nodes from the name index v2 B-tree,
if an attribute is found in the intermediate B-tree nodes, which may be
merged/redistributed in the process, we need to free the dynamically
allocated spaces for the intermediate decoded attribute.
--src/H5PB.c: checks for size >= page size
--src/H5MF.c: disable/enable page buffering in H5MF_tidy_self_referential_fsm_hack()
--src/H5MFsection.c: call H5PB_remove_entry() for both raw/metadata pages in H5MF__sect_small_merge()
(B) Port and modify existing concurrent swmr tests to VFD SWMR. Also modify the following:
--remove flushes from VFD SWMR writer tests
--set Nreaders to 0 in test/testvfdswmr.sh.in to test for writers only
