* Added support for vector I/O calls to the VFD layer, and
associated test code. Note that this includes the optimization
to allow shortened sizes and types arrays to allow more space
efficient representations of vectors in which all entries are
of the same size and/or type. See the Selection I/o RFC for
further details.
Tested serial and parallel, debug and production on Charis.
serial and parallel debug only on Jelly.
* ran code formatter
quick serial build and test on jelly
* Add H5FD_read_selection() and H5FD_write_selection(). Currently only
translate to scalar calls. Fix const buf in H5FD_write_vector().
* Format source
* Fix comments
* Add selection I/O to chunk code, used when: not using chunk cache, no
datatype conversion, no I/O filters, no page buffer, not using collective
I/O. Requires global variable H5_use_selection_io_g be set to TRUE.
Implemented selection to vector I/O transaltion at the file driver
layer.
* Fix formatting unrelated to previous change to stop github from
complaining.
* Add full API support for selection I/O. Add tests for this.
* Implement selection I/O for contiguous datasets. Fix bug in selection
I/O translation. Add const qualifiers to some internal selection I/O
routines to maintain const-correctness while avoiding memcpys.
* Added vector read / write support to the MPIO VFD, with associated
test code (see testpar/t_vfd.c).
Note that this implementation does NOT support vector entries of
size greater than 2 GB. This must be repaired before release,
but it should be good enough for correctness testing.
As MPIO requires vector I/O requests to be sorted in increasing
address order, also added a vector sort utility in H5FDint.c This
function is tested in passing by the MPIO vector I/O extension.
In passing, repaired a bug in size / type vector extension management
in H5FD_read/write_vector()
Tested parallel debug and production on charis and Jelly.
* Ran source code formatter
* Add support for independent parallel I/O with selection I/O. Add
HDF5_USE_SELECTION_IO env var to control selection I/O (default off).
* Implement parallel collective support for selection I/O.
* Fix comments and run formatter.
* Update selection IO branch with develop (#1215)
Merged branch 'develop' into selection_io
* Sync with develop (#1262)
Updated the branch with develop changes.
* Implement big I/O support for vector I/O requests in the MPIO file
driver.
* Free arrays in H5FD__mpio_read/write_vector() as soon as they're not
needed, to cut down on memory usage during I/O.
* Address comments from code review. Fix const warnings with
H5S_SEL_ITER_INIT().
* Committing clang-format changes
* Feature/subfiling (#1464)
* Initial checkin of merged sub-filing VFD.
Passes regression tests (debug/shared/paralle) on Jelly.
However, bugs and many compiler warnings remain -- not suitable
for merge to develop.
* Minor mods to src/H5FDsubfile_mpi.c to address errors reported by autogen.sh
* Code formatting run -- no test
* Merged my subfiling code fixes into the new selection_io_branch
* Forgot to add the FindMERCURY.cmake file. This will probably disappear soon
* attempting to make a more reliable subfile file open which doesn't return errors. For some unknown reason, the regular posix open will occasionally fail to create a subfile. Some better error handling for file close has been added.
* added NULL option for H5FD_subfiling_config_t in H5Pset_fapl_subfiling (#1034)
* NULL option automatically stacks IOC VFD for subfiling and returns a valid fapl.
* added doxygen subfiling APIs
* Various fixes which allow the IOR benchmark to run correctly
* Lots of updates including the packaging up of the mercury_util source files to enable easier builds for our Benchmarking
* Interim checkin of selection_io_with_subfiling_vfd branch
Moddified testpar/t_vfd.c to test the subfiling vfd with default configuration.
Must update this code to run with a variety of configurations -- most particularly
multiple IO concentrators, and stripe depth small enough to test the other IO
concentrators.
testpar/t_vfd.c exposed a large number of race condidtions -- symtoms included:
1) Crashes (usually seg faults)
2) Heap corruption
3) Stack corruption
4) Double frees of heap space
5) Hangs
6) Out of order execution of I/O requests / violations of POSIX semantics
7) Swapped write requests
Items 1 - 4 turned out to be primarily caused by file close issues --
specifically, the main I/O concentrator thread and its pool of worker threads
were not being shut down properly on file close. Addressing this issue in
combination with some other minor fixes seems to have addressed these issues.
Items 5 & 6 appear to have been caused by issue of I/O requests to the
thread pool in an order that did not maintain POSIX semantics. A rewrite of
the I/O request dispatch code appears to have solved these issues.
Item 7 seems to have been caused by multiple write requests from a given
rank being read by the wrong worker thread. Code to issue "unique" tags for
each write request via the ACK message appears to have cleaned this up.
Note that the code is still in poor condtition. A partial list of known
defects includes:
a) Race condiditon on file close that allows superblock writes to arrive
at the I/O concentrator after it has been shutdown. This defect is
most evident when testpar/t_subfiling_vfd is run with 8 ranks.
b) No error reporting from I/O concentrators -- must design and implement
this. For now, mostly just asserts, which suggests that it should be
run in debug mode.
c) Much commented out and/or un-used code.
d) Code orgnaization
e) Build system with bits of Mercury is awkward -- think of shifting
to pthreads with our own thread pool code.
f) Need to add native support for vector and selection I/O to the subfiling
VFD.
g) Need to review, and posibly rework configuration code.
h) Need to store subfile configuration data in a superblock extension message,
and add code to use this data on file open.
i) Test code is inadequate -- expect more issues as it is extended.
In particular, there is no unit test code for the I/O request dispatch code.
While I think it is correct at present, we need test code to verify this.
Similarly, we need to test with multiple I/O concentrators and much smaller
stripe depth.
My actual code changes were limited to:
src/H5FDioc.c
src/H5FDioc_threads.c
src/H5FDsubfile_int.c
src/H5FDsubfile_mpi.c
src/H5FDsubfiling.c
src/H5FDsubfiling.h
src/H5FDsubfiling_priv.h
testpar/t_subfiling_vfd.c

This exposed issues with truncate and get EOF in the sub-filing VFD.
I believe I have addressed these issues (get EOF not as fully tested as it should be), howeer,
it exposed race conditions resulting in hangs. As of this writing, I have not been able
to chase these down.
Note that the tests that expose these race conditions are in testpar/t_subfiling_vfd.c, and
are currently skipped. Unskip these tests to reproduce the race conditions.

Tested on: h5committest
Description:
Added internal tesitng routines to traverse a file and verify that symbol table
information is *always* cached, whenever possible. Added this check to the end
of many tests to check all the test files, right before the call to h5_cleanup.
Tested: jam, amani, heiwa (h5committest)
Description:
A bug introduced in 1.8.5 causes local heap data blocks to be mis-aligned when
sizeof_offsets + 2*sizeof_lengths is not a multiple of 8. In this case, the
address of the data block as stored in the heap prefix is aligned but the actual
data block is not. This causes files created with these sizes to be corrupted,
and prevents uncorrupted files with these sizes to be unreadable. Modified
local heap code to account for alignment.
Tested: jam, amani, linew (h5committest)
Commit metadata tagging framework.
Description:
This check-in contains a new framework whose goal is to apply
a tag value to each new entry in the metadata cache as it is created.
This tag value is such that it relates each piece of metadata to the
HDF5 object that it belongs to (dataset, group, et cetera).
This changeset includes the framework that applies the tags as
well as a suite of tests to verify correct tag application, though does
not yet make use of the tag values to flush/evict individual objects.
Please refer to the "flush/evict individual objects" RFC for further
discussion of these changes.

Fix problems with 'check-vfd' target, that were [mostly] introduced with
the recent "unique, but sharable" ISOHM optimization.
The problems were mostly with using the 'core' VFD, so the
H5Pset_fapl_core() API call was changed to re-open existing files (therefore
operating more list the sec2, stdio, etc. VFDs). This allows many more of
the tests to run using the 'core' VFD, so those were enabled also.

"make check-vfd" will now run all tests in the test directory with different
file drivers (at least, all of those tests that use the testing framework's
FAPL). Tests that fail will be skipped.
This is not a perfect fix, but is better than nothing.
Along with this change, check-vfd should be added to the Daily Tests.
Code cleanup

Platforms tested:

Feature: tests now use parallel make and only run once
Description:
When make is invoked in parallel (using the -j option), several tests will
now be run simultaneously. This should speed up testing on a number of
systems.
When a test passes, it creates a foo.chkexe or foo.chksh file, which prevents
the test from running again unless the test or library changes.
Solution:
Most of the changes live in config/conclude.am. Added *.chkexe and *.chksh
files to the list of files to be cleaned at "make mostlyclean" time.
Parallel tests still run one at a time, but use the same make instructions
as serial tests.
Platforms tested:
mir, eirene, sleipnir, pommier, copper, modi4 (some errors occurred, probably
due to the test being run before updating hdf5. Will re-run tests after
checkin.)
Interim checkin of code changes moving management of the is_dirty flag
into the cache code.
Description:
Prior to this checkin, management of the is_dirty flag was handled
above the level of the metadata cache. This can no longer be allowed,
as it introduces a race condition in the proposed fix for a cache
coherency bug in PHDF5.
Solution:
Move management fo the is_dirty flag to the cache code proper.
Entries are now marked as dirty via a flag on the unprotect call.
Platforms tested:
h5committested
Misc. update:
Description: Restore 6 old error API functions back to the library to be backward
compatible with v1.6. They are H5Epush, H5Eprint, H5Ewalk, H5Eclear, H5Eset_auto,
H5Eget_auto. These functions do not have error stack as parameter.
Solution: Internally, these functions use default error stack.
Platforms tested: h5committest and fuss.

Description:
Clean up a bunch of warnings and bring new code better inline with current
library coding practice.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
Too minor to require h5committest

Purpose:
Bug Fix
Description:
If an HDF5 file grows larger than its address space, it dies and is unable to
write any data. This is more likely to happen since users are able to change
the number of bytes used to store addresses in the file.
Solution:
HDF5 now throws an error instead of dying. In addition, it "reserves" address
space for the local heap and for object headers (which do not allocate space
immediately). This ensures that after the error occurs, there is enough address
space left to flush the entire file to disk, so no data is lost.
