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!
Check for smaller or larger section size after merging and shrinking a section,
for this case is the section that is smaller than threshold (see H5MF_xfree() in H5MF.c).
It is possible for the section to be smaller after merging/shrinking (see H5MF__sect_large_shrink()
in H5MFsection.c).
Given that the VFD SWMR configuration FAPL property is set, the writer field must
be consistent with the flags passed in the H5Fopen() (either H5F_ACC_RDWR for the
VFD SWMR writer, or H5F_ACC_RDONLY for the VFD SWMR readers).
The test "driver_addr != sblock->driver_addr" is failing for superblock version 2 & 3.
Fix: there is no driver_addr in superblock version 2 & 3.
It should decode the root group object header address (root_addr) and verify accordingly.
(A) #5: Add the "pb_expansion_threshold" field to the "H5F_vfd_swmr_config_t" structure
and update H5Pset_vfd_swmr_config() and H5Pget_vfd_swmr_config() accordingly
(B) #13 bullet 2: Comment H5F_vfd_swmr_config_t in H5Fpublic.h properly
(copied from John's description in the RFC)
(C) Change the field name "vfd_swmr_writer" to "writer" in "struct H5F_vfd_swmr_config_t"
(as indicated on page 11 in the RFC) and all references to it
had finished its work and closed the .h5 file, thus removing the shadow file.
Make the sparse writer wait to close the .h5 file for a signal from
testvfdswmr.sh. In testvfdswmr.sh, send the signal when the readers have all
finished.
This lets test/testflushrefresh.sh pass again. It was timing out while it
waited for expected failures to occur because the retry loop ran for way too
long.
cells in a matrix in an arbitrary order, first it chooses a random
starting `offset` in [0, rows * columns - 1]. Then it chooses a
random `increment` that's relatively prime to `rows * columns`.
Then it visits every cell in `rows * columns` steps:
for (i = 0; i < rows * columns; i++) {
visit(cell[offset / columns][offset % columns]);
offset = (increment + offset) % (rows * columns);
}
By moving the HDrandom() calls outside of the main loop and visiting
each cell only once, this probably speeds things up quite a bit. It's
also more resilient to a crummy random sequence. The new code visits
cells in an order that's probably arbitrary enough for testing purposes.
to end with whitespace padding rather than newlines. My introduction of
variadic TESTING() got rid of the padding. I have straightened this out
by newline-terminating the stdout lines in the test program and in its
expected out. I also add some newlines to the program's standard error
output so that the expected error output still matches.
comment to myself that I need to reduce code duplication with the MPMDE
test.
In vfd_read_each_equals(), print the correct expected value when there
is a discrepancy.
No functional change intended: correct a comment in
vfd_read_each_equals. Fix indentation in the test_raw_data_handling()
header comment.
