Bug fix (feature, kind of)
Description:
The library used to hang if a collective dataset read/write request
does not have the same number of eventual MPIO request. Part of the
reason is that H5FD_read/H5FD_write immediately returns succeess
if it sees the request size is 0. This caused problem since other
processes with I/O to do would be hanging by waiting for the early
returned process(es).
Solution:
H5FD.c: disable the early return code in parallel mode. Make it
go on even with "nothing" to transfer.
H5D.c: the optimized MPIO xfer routines can handle collect calls correctly
when the condition is right (e.g., no conversion). When the COLLECTIVE
request cannot be handled correctly without the risk of hanging, the
COLLECTIVE is changed to INDEPENDENT calls for the eventual MPIO
calls.
Platforms tested:
IRIX64 parallel (-64, n32), IRIX64 -64 sequential, Linux sequential.

* 2000-11-10 Robb Matzke <matzke@llnl.gov> (H5FD_close)
Removed code that resets the H5FD_t
file structure to zero because that struct has already been
freed. This fixes a core dump on some platforms.

Purpose:
Bug fix
Description:
H5FD_close() wiped clean the public information before
closing the FD. This caused problem to the lower level
close() which wants to verify it has indeed handed a valid
file-driver to close because that information is wiped out
prematurely.
Solution:
Moved the public information part cleaning after it is closed.
H5FDmpio.c:
Added in a bunch of assertion to make sure the file handle is indeed
an MPIO file.
Platforms tested:
IRIX64 -64 parallel

Feature symmetry
Description:
A while ago I needed to get the 'type' of data being accessed during writes
to the VFL driver, so I put in code to get the information down there.
Albert asked for the same information during reads, so I've added that in.
Tested:
FreeBSD 4.1.1 (hawkwind)

Maintainance & performance enhancements
Description:
Re-arranged header files to protect private symbols better.
Changed optimized regular hyperslab I/O to compute the offsets more
efficiently from previous method of using matrix operations.
Added sequential I/O operations at a more abstract level (at the same level
as H5F_arr_read/write), to support the optimized hyperslab I/O.
Platforms tested:
Solaris 2.6 (baldric) & FreeBSD 4.1.1 (hawkwind)

structures. Also
added code to allow metadata to be allocated out of a more contiguous block
("metadata aggregation") and also code for "catching" small metadata write
calls and building a buffer of the small pieces of metadata for later writing
as one, larger, block ("metadata accumulation"). These features are enabled
on a per VFL driver basis with the new VFL 'query' call and both currently
enabled for the sec2, family and stdio drivers. The mpio VFL driver enables
only the "metadata aggregation" code, not the "metadata accumulation" code.
All the other drivers have these features turned off.

./configure.in
./src/H5config.h.in [REGENERATED]
The /usr/ncsa/{include,lib} directories are only added if they
actually exist. This fixes a warning on some systems.
Checks for the <pdb.h> header file and also for either the PDB or Silo
library, and if found prepares to compile the pdb2hdf program.
./config/distdep
Relative path names for include files are changed to base names since
the makefile contains the logic for searching and since it's likely
that building the .distdep files happed from a location other than
where they would be used in the file system.
./config/conclude.in
Fixed shell errors when `for' loops iterate over nothing for the
`uninstall' target.
./src/H5D.c
./src/H5Oefl.c
File names for the external files are added to the heap when the
dataset is created instead of when the object header is written. This
fixes a rare infinite recursion bug.
./src/H5FD.c
./src/H5FDpublic.h
Optimization to the free list causes H5FD_alloc() usage to go from >10
seconds to <0.4 second for one example (converting a 30MB equation of
state file from PDB to HDF5 format). The optimization is to simply
keep track of the largest item in the free list and not search the
free list when the largest item is not big enough to satisfy the
request.
./src/H5FDcore.c
./src/H5FDcore.h
./test/h5test.c
If the `backing_store' property is true then a flush causes the entire
contents of memory to be written to the specified file. This is in
preparation for the ASCI/red optimizations and is currently tested by
the pdb2hdf `--cached' switch.
./src/H5Odtypes.c
Wrapped three long lines.
./tools/Makefile.in
./tools/pdb2hdf.c [NEW]
A PDB-to-HDF5 translator. It only translates meta data -- the
resulting HDF5 points into the PDB file for the raw data.

Minor changes done to test/gass_xxx.c so that they print the
test skip message when GASS driver is not available.
This change is the implementation of GASS within HDF5-1.3 (HDF5 with Virtual
File Layer). The GASS driver gives the facility of accessing HDF files on
remote ftp servers. To use the GASS driver, the option --with-gass=<GASS path>
shoud be specified with configure. An example of the command line used to
test the distribution was:
./configure --disable-shared --without-hdf4
--with-gass=/afs/ncsa/projects/hdf/v5/bagchi/globus/GLB/development/sparc-sun-solaris2.6_nothreads_standard_debug/include,/afs/ncsa/projects/hdf/v5/bagchi/globus/GLB/development/sparc-sun-solaris2.6_nothreads_standard_debug/lib
--disable-parallel
The user should change the path to point to his local GASS installation.
Documentation about the features of GASS and the HDF-GASS design is available
separately and till it is put up on the official web site, anyone interested
may contact me.
Test programs to read, write or append remote files have been provided in the
test directory as "gass_read.c", "gass_write.c", "gass_append.c". The test
programs have the ftp site to access #define-d at the top of the file which
the user can change accordingly.
./src/H5Epublic.
Added new error type for file close.
./src/H5F.c
Added hooks for the GASS driver.
./src/H5public.h
Added header files for GASS & Globus.
./src/Makefile.in
Added dependancy on GASS driver in LIB_SRC.
./src/hdf5.h
Included header file for GASS driver.
./src/H5FDgass.c [NEW]
Routines for the GASS driver.
./src/H5FDgass.h [NEW]
Header file for the GASS driver.
./test/Makefile.in
Added dependancy on the gass test routines.
./test/gass_read.c
File to test remote file reading using GASS.
./test/gass_write.c
File to test remote file writing using GASS.
./test/gass_append.c
File to test remote file appending using GASS.

----------------------
./src/H5D.c
Added additional elements to a variable initializer in
H5Dvlen_get_buf_size() to shut up a warning message. Also
added the API tracing call.
./src/H5F.c
Added file opening optimizations. If the driver doesn't
support the ability to determine when two file handles refer
to the same file (like MPIO and GASS) then H5F_open() makes
fewer calls to the driver's open callback. Also, if the
tentative file access flags are the same as the original flags
then H5F_open() makes fewer calls to the file device.
./src/H5FD.c
./src/H5FDprivate.h
./src/H5FDpublic.h
Added H5FD_get_class() so the library can get information
about what file driver callbacks are defined. This will be
useful when more optimization functions are added to the VFL,
such as for MPIO derived datatype I/O.
./src/H5FDcore.c
./src/H5FDfamily.c
./src/H5FDmpio.c
./src/H5FDmulti.c
./src/H5FDsec2.c
The driver symbols (like H5FD_CORE, etc) are actually function
calls. The functions were fixed to return correct values even
after calling H5close().
./src/H5FDmulti.c
./src/H5FDmulti.h
Added support for opening a file when parts are missing (only
if the caller explicitly allows that in the file access
property list).
Moved some common code sequences into macros or functions.
Added better support for reopening files. All the application
has to know is that the file is a multi file and the base name
from which all the member names are created.
More debugging output when the file is opened with the
H5F_ACC_DEBUG flag.
Fixed various bugs.
./src/H5Fistore.c
Chunked raw data was accidently allocated as meta data instead
of raw data.
./src/H5I.c
The H5Iget_type() function fails when invoked with an old
object ID (an ID which has been closed down).
./test/h5test.c
Added an extra argument when setting the multi file access
property lists so the test fails if it can't open one of the
sub-files.
./tools/h5ls.c
Improved the algorithm for deciding what file driver to
use. It basically tries all of the predefined drivers and is
now able to open family, split, and multi files without
looking for special characters in the file name.
Added `-e' and `--errors' switches which cause errors from
libhdf5 to be reported on stderr in addition to the simple
error message displayed by h5ls.

./src/H5FDmulti.c [NEW]
./src/H5FDmulti.h [NEW]
./src/Makefile.in
./src/hdf5.h
The split driver was reimplemented as a more general "multi"
driver which is capable of splitting data into multiple files
like the family driver except the partioning is done by memory
usage type instead of address. The H5Pset_fapl_split()
function just calls H5Pset_fapl_multi() with arguments which
prepare to split the address space into two files: meta and
raw data.
This is the first version. I plan to allow the open() call to
relax a bit which would allow one to open an hdf5 file when
only the meta-data file is present. This would allow a very
large file to be split and stored on tape and the relatively
small meta file to be mirrored on disk to allow limited
browsing of the file (any request for raw data would fail).

./src/H5FDpublic.h
./src/H5FDcore.c
./src/H5FDfamily.c
./src/H5FDmpio.c
./src/H5FDsec2.c
Added the ability for a file driver to store information in
the superblock which would be needed if the file were opened
again later for reading. The format is driver-defined which
allows users to extend it however they like.
./doc/html/H5.format.html
Added information about the new driver information block of
the superblock. This is where file drivers store information
they need in order to reopen the file later.

./src/H5R.c
The file access properties and the file access property list
were decoupled, which allows the property list to more cleanly
contain properties for various levels of the file and which
allows the property list to be modified more cleanly when
opening files.
./src/H5.c
./src/H5FDpublic.h
Removed H5FD_MEM_META and H5FD_MEM_GROUP since they're never
used.
./src/H5D.c
Changed the way we detect the MPIO driver in all these special
cases.
./src/H5F.c
./src/H5Rpublic.h
./test/tfile.c
The default file sizeof(offset) was changed to be a function
of haddr_t instead of hsize_t.
THE H5RPUBLIC.H DEFINITIONS WILL HAVE PROBLEMS IF THE USER
CREATES A FILE WITH NON-DEFAULT OFFSET AND SIZE SIZES!
./src/H5F.c
Fixed an uninitialized memory access bug in file closing
related to the VFL.
./src/H5T.c
./src/H5Tpublic.h
Added an H5T_NATIVE_HADDR predefined datatype which
corresponds to the `haddr_t' type.
./test/Makefile.in
Reformatted long lines.
./test/big.c
./test/cmpd_dset.c
./test/dsets.c
./test/dtypes.c
./test/extend.c
./test/external.c
Removed the H5F_ACC_DEBUG flag from file creation/open calls.
./test/big.c
Plugged a memory leak.
./test/h5test.c
Added support for the `multi' driver.
Removed #warning about not having the stdio driver. Plans are
to not implement it since the sec2 driver serves the same
purpose and testing didn't show any difference in execution
times between the two.
|
|
|
----------------------
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.

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.
