Removal of H5AC_find()
Description:
The H5AC_find() function is mostly redundant and with the new
Flexible Parallel HDF5 stuff, we need to do locking on metadata
returned from the H5AC_find() anyway. So, all of the locking stuff
will be placed in the H5AC_{un}protect() functions. The H5AC_find()
is no longer needed.
Solution:
Replaced all H5AC_finds with H5AC_protects and H5AC_unprotects.

Bug fix
Description:
The metadata cache 'destroy' callback routines need the file handle in
order for certain callback routines (currently just the H5HG one) to perform
extra cleanups. The recent change to call the 'destroy' callback from the
'clear' callback omitted this parameter.
Solution:
Add the file handle to the metadata cache 'clear' callbacks.

Update
Description:
Added an extra flag to the clear functions that triggers a "destroy"
of the object being cleared if necessary. This is a fix for the
FPHDF5 stuff which had an object sticking around after it was
cleared. (In FPHDF5, some processes are in charge of destroying the
object, but all processes might actually allocate the object.)

Code cleanup, bug fix & new feature.
Description:
Moved some "package-scope" information out of the private header file and
into the code module. (code cleanup).
Fixed a few places where the "destroy but don't flush" code wasn't working
correctly, which mostly affects the FPH5 effort. (bug fix).
Added the ability to "unprotect" a metadata object and delete it at the
same time. (new feature).

Bug Fix
Description:
Metadata cache in parallel I/O can cause hangs in applications which
perform independent I/O on chunked datasets, because the metadata cache
can attempt to flush out dirty metadata from only a single process, instead
of collectively from all processes.
Solution:
Pass a dataset transfer property list down from every API function which
could possibly trigger metadata I/O.
Then, split the metadata cache into two sets of entries to allow dirty
metadata to be set aside when a hash table collision occurs during
independent I/O.

Lots of performance improvements & a couple new internal API interfaces.
Description:
Performance Improvements:
- Cached file offset & length sizes in shared file struct, to avoid
constantly looking them up in the FCPL.
- Generic property improvements:
- Added "revision" number to generic property classes to speed
up comparisons.
- Changed method of storing properties from using a hash-table
to the TBBT routines in the library.
- Share the propery names between classes and the lists derived
from them.
- Removed redundant 'def_value' buffer from each property.
- Switching code to use a "copy on write" strategy for
properties in each list, where the properties in each list
are shared with the properties in the class, until a
property's value is changed in a list.
- Fixed error in layout code which was allocating too many buffers.
- Redefined public macros of the form (H5open()/H5check, <variable>)
internally to only be (<variable>), avoiding innumerable useless
calls to H5open() and H5check_version().
- Reuse already zeroed buffers in H5F_contig_fill instead of
constantly re-zeroing them.
- Don't write fill values if writing entire dataset.
- Use gettimeofday() system call instead of time() system when
checking the modification time of a dataset.
- Added reference counted string API and use it for tracking the
names of objects opening in a file (for the ID->name code).
- Removed redundant H5P_get() calls in B-tree routines.
- Redefine H5T datatype macros internally to the library, to avoid
calling H5check redundantly.
- Keep dataspace information for dataset locally instead of reading
from disk each time. Added new module to track open objects
in a file, to allow this (which will be useful eventually for
some FPH5 metadata caching issues).
- Remove H5AC_find macro which was inlining metadata cache lookups,
and call function instead.
- Remove redundant memset() calls from H5G_namei() routine.
- Remove redundant checking of object type when locating objects
in metadata cache and rely on the address only.
- Create default dataset object to use when default dataset creation
property list is used to create datasets, bypassing querying
for all the property list values.
- Use default I/O vector size when performing raw data with the
default dataset transfer property list, instead of querying for
I/O vector size.
- Remove H5P_DEFAULT internally to the library, replacing it with
more specific default property list based on the type of
property list needed.
- Remove redundant memset() calls in object header message (H5O*)
routines.
- Remove redunant memset() calls in data I/O routines.
- Split free-list allocation routines into malloc() and calloc()-
like routines, instead of one combined routine.
- Remove lots of indirection in H5O*() routines.
- Simplify metadata cache entry comparison routine (used when
flushing entire cache out).
- Only enable metadata cache statistics when H5AC_DEBUG is turned
on, instead of always tracking them.
- Simplify address comparison macro (H5F_addr_eq).
- Remove redundant metadata cache entry protections during dataset
creation by protecting the object header once and making all
the modifications necessary for the dataset creation before
unprotecting it.
- Reduce # of "number of element in extent" computations performed
by computing and storing the value during dataspace creation.
- Simplify checking for group location's file information, when file
has not been involving in file-mounting operations.
- Use binary encoding for modification time, instead of ASCII.
- Hoist H5HL_peek calls (to get information in a local heap)
out of loops in many group routine.
- Use static variable for iterators of selections, instead of
dynamically allocation them each time.
- Lookup & insert new entries in one step, avoiding traversing
group's B-tree twice.
- Fixed memory leak in H5Gget_objname_idx() routine (tangential to
performance improvements, but fixed along the way).
- Use free-list for reference counted strings.
- Don't bother copying object names into cached group entries,
since they are re-created when an object is opened.
The benchmark I used to measure these results created several thousand
small (2K) datasets in a file and wrote out the data for them. This is
Elena's "regular.c" benchmark.
These changes resulted in approximately ~4.3x speedup of the
development branch when compared to the previous code in the
development branch and ~1.4x speedup compared to the release
branch.
Additionally, these changes reduce the total memory used (code and
data) by the development branch by ~800KB, bringing the development
branch back into the same ballpark as the release branch.
I'll send out a more detailed description of the benchmark results
as a followup note.
New internal API routines:
Added "reference counted strings" API for tracking strings that get
used by multiple owners without duplicating the strings.
Added "ternary search tree" API for text->object mappings.

Bug Fix
Description:
It was possible to create corrupted metadata information (either in memory
or in the file or both) with a parallel I/O program because of the way
metadata writes were being handled for writes out of the metadata cache.
Solution:
Added a dataset transfer property called "block before metadata write"
which is used by the MPI-I/O and MPI-posix drivers to sync up all the
processes before attempting a metadata write. This property is currently
only for metadata writes from the metadata cache.

Code cleanup
Description:
Broke the FUNC_ENTER macro into several macros, with more specialized
uses (which followup mail will describe). This was designed to move
most/all of the checks which could be done at compile time to that point,
instead of needlessly performing them (over & over :-) at run-time.
This reduces the library's size (and thus staticly linked binaries) and
has a minor speedup effect also.
Platforms tested:
IRIX64 6.5 (modi4) with parallel & FORTRAN enabled, and additional testing
on FreeBSD and Solaris immediately after the checkin.

Code cleanup.
Description:
Took Robb's recent ideas for improving the FUNC_ENTER/FUNC_LEAVE macros
equivalents in the SAF library and adapted them to our library. I added
an additional macro which is equivalent to FUNC_ENTER:
FUNC_ENTER_NOINIT - Has the API tracing code, etc. from FUNC_ENTER but
none of the library or interface initialization code. This is to
be used _only_ for static functions and those which explicitly
cannot have the library or interface initialization code enabled
(like the API termination routines, etc.).
This allowed many more of the functions in the library [but not all yet :-(]
to be wrapped with FUNC_ENTER[_NOINIT]/FUNC_LEAVE pairs.
It also reduced the size of the library and executables (by cutting out a
bunch of code which was never executed), I'll e-mail the exact results when
I've finished editing it.

Code cleanup (sorta)
Description:
When the first versions of the HDF5 library were designed, I remembered
vividly the difficulties of porting code from a 32-bit platform to a 16-bit
platform and asked that people use intn & uintn instead of int & unsigned
int, respectively. However, in hindsight, this was overkill and
unnecessary since we weren't going to be porting the HDF5 library to
16-bit architectures.
Currently, the extra uintn & intn typedefs are causing problems for users
who'd like to include both the HDF5 and HDF4 header files in one source
module (like Kent's h4toh5 library).
Solution:
Changed the uintn & intn's to unsigned and int's respectively.

Code clean/bug fix
Description:
H5FL (free-list manager) code currently is taking an hsize_t as the size
of a memory block to allocate. On many machines, the size of an hsize_t
is greater than the size of a size_t, potentially leading to incorrect
memory allocations in rare circumstances.

Changed hsize_t parameters and variables to size_t.

Bug fix (sort of)
(H5FDgass.c: just deleted an old code. Nothing to do with this fix.)
Description:
When --enable-debug=all was used, couple routine printf warnings
to stderr that it is an expensive operation. This messed up
the testing of h5ls since it included stderr output in its expected
output and did not expect the extra messages.
Solution:
Changed it such that the extra messages are printed only
if the appropriate h5-debug-class setting is on (via environment
variables, for example).

----------------------
This extensive change is the virtual file layer implementation. I've
ported and tested the sec2, family, and core drivers and only ported
the mpio driver (Albert will test it). So if you need MPIO I would
recommend sticking with the previous version for a while.
You will get a few compile warnings about split and stdio drivers not
being implemented and possibly tracing information not inserted in
some of the drivers. You can safely ignore them but I plan to fix
them.
I'm still working on the split driver because I just realized that it
needs a part of the VFL that isn't written yet.
Documentation is being updated also because there were some minor
changes (mostly just name changes). It should be available on my web
site later this week.

Removed the H5F_OPT_SEEK and H5F_LOW_DFLT constants from the
configuration since they're no longer applicable. The default
file driver is always the sec2 driver and it always optimizes
calls to lseek() or lseek64().
./config/depend.in
C preprocessor errors generated during automatic dependency
building are sent to /dev/null to prevent them from appearing
twice in the make output.

because the properties apply to all types of I/O operations,
not just datasets.

Modified to work with the virtual file layer by calling H5FD_*
functions instead of H5F_low_* functions and by passing file
access and data transfer properties by object ID instead of
pointer.
Changed H5D_transfer_t to H5FD_mpio_xfer_t since the
COLLECTIVE vs. INDEPENDENT transfer mode is specific to the
MPIO file driver.
Moved MPIO-specific stuff into the MPIO driver.
./src/H5B.c
./src/H5D.c
./src/H5Fprivate.h
The H5F_mpio_* private functions were renamed and placed in
the H5FDmpio driver except those which appeared in H5Smpio.c.
./src/H5E.c
./src/H5Epublic.h
Added major error number H5E_VFL for virtual file layer
related errors.
./src/H5F.c
./src/H5Fprivate.h
Changed the logic that controls whether the boot block is
written. Instead of assuming that the first call to write the
boot block is only to allocate space, I've added a function
argument which makes this explicit.
Changed the way files are compared so that a driver-defined
comparison function can be called. Files which belong to
different drivers are always considered different.
Removed H5F_driver_t since file drivers are now identified by
object ID instead of a special non-user-extendible datatype.
Removed all the hard-coded low-level file properties which
have been replaced by the various file drivers.
./src/H5I.c
./src/H5Iprivate.h
Added the H5I_inc_ref() which was removed a few months ago
since we finally have a use for it.
./src/H5Ipublic.h
Added the H5I_VFL object ID type to identify file drivers in
the virtual file layer.
./src/H5MF.c
./src/H5MFprivate.h
Moved all the allocation/deallocation code into the virtual
file layer which allows file drivers to override much of it.
./src/H5P.c
./src/H5Ppublic.h
Moved file driver-specific code into the various file driver
files.
The H5Pcopy() and H5Pclose() functions make calls into the
virtual file driver to manage the memory for driver-specific
file access and data transfer properties.
./src/H5private.h
./src/H5public.h
The `haddr_t' type is now public.
./test/tfile.c
Added a few more comments.

Changes since 19990618
----------------------
./configure.in
./configure [REGENERATED]
Now that compound struct conversions don't make so many calls
to convert their members I turned the H5T debugging back on by
default (it will still be disabled in a production version).
./src/H5AC.c
./src/H5B.c
Made it possible to turn off messages about debugging these
two packages using the same method as for all other
packages. Just supply an invalid file descriptor number or use
the shell to redirect said descriptor to /dev/null like this:
$ HDF5_DEBUG=99,ac,b 99>/dev/null a.out
./src/H5T.c
Changed the name of the old compound conversion function from
`struct' to `struct(no-opt)' to be more consistent with the
new version named `struct(opt)'.
Fixed a bug in H5T_cmp() that caused any two VL types to
compare as being equal.
Removed duplicate code for bitfield comparisons in H5T_cmp().
./src/H5Tconv.c
Relaxed some constraints in the new compound conversion
function so it applies to more cases. Also eliminated a
memcpy in a tight loop.
./test/cmpd_dset.c
Added a `--noopt' command line switch which unregisters the
optimized compound conversion so we can test the non-optimized
version.

header files.
./src/H5Tpkg.h
./test/h5test.h
Removed __unused__ from forward function declarations.
./src/H5P.c
Removed a comment about restrictions for the type conversion
temporary buffers. Thanks to Quincey, the comment no longer
applied.
./src/H5T.c
Relaxed the H5Tpack() a little so it would pack compound data
structures that had non-transient atomic members.
./tools/h5ls.c
Added a `-g' (or `--group') flag that causes information to be
printed about the specified group instead of the group's
contents. (sort of like Unix's `ls -d'). The `-g' can be used
in combination with `-r' to print information about the group
and its contents.

Most of these changes are because the `interface_initialize_g'
variable change from hbool_t to int. It's a one line change.
Changed the way the library is closed so we have more control
over the order the interfaces are shut down. Instead of
registering an atexit() function for every interface in some
haphazard order we just register one: H5_term_library() which
then calls the H5*_term_interface() functions in a
well-defined order.
If the library is closed and then reopened repeatedly by
calling H5close() and H5open() in a loop we only add one copy
of the library termination functions with atexit().
Termination is a two-step process in order to help detect
programming errors that would cause an infinite loop caused by
the termination of one interface waking up some other
previously terminated interface. The first step terminates
the interface and *marks it as unusable*. After all
interfaces are terminated then we mark them all as usable
again. The FUNC_ENTER() macro has been modified to return
failure or to dump core (depending on whether NDEBUG is
defined) if we try to call an interface while it's shutting
down.
./src/H5.c
The H5dont_atexit() function returns failure if it's called
more than once or if it's called too late. However, the error
stack is not automatically printed on failure because the
library might not be initialized yet
./test/chunk.c
./test/flush1.c
./test/flush2.c
./test/iopipe.c
./test/overhead.c
./test/ragged.c
Changed the extra cast for Win32 so we do floating point
division again -- it was just confusion about precedence and
associativity of casting and the C coercion rules. Removed
extra carriage returns inserted by broken operating system.
./src/H5Ffamily.c
Fixed an bug where H5F_fam_write() lowered the EOF marker for
one of the family members causing H5F_fam_read() to read
zeros.
./test/h5test.h [NEW]
./test/h5test.c [NEW]
./test/Makefile.in
./test/bittests.c
./test/cmpd_dset.c
./test/dsets.c
./test/dtypes.c
./test/extend.c
./test/external.c
Support library for test files. This isn't done yet but
Katie's contractions are ~10 minutes apart so I figured I
better back this stuff up just in case I'm not here next
week...
Eventually all test files will understand HDF5_DRIVER to name
the low level file driver and parameters so we can easily test
various drivers. They will also understand HDF5_PREFIX to
prepend to the beginning of file names which is necessary for
testing ROMIO with various drivers. Also, the cleanup function
will know how to use the file name prefix and will understand
different file driver naming schemes like file families. I'm
not sure they'll understand the `gsf:' type prefixes yet.
Note, the external test is completely commented out because
I'm in the middle of modifying it. It will still compile and
run but it doesn't test anything at the moment.
