Removed H5Pset_compression (commented it out, actually) and
changed example which used it to use H5Pset_deflate.
H5.format.html
Driver Identification block: Added clarification regarding the
representation of the version in the driver identification string.
H5.format.html
Merged R1.2 and R1.4 (development tree) versions.
Fixed centered paragraphs and moved first two figures to right
margin.
FF-IH_FileGroup.gif and FF-IH_FileObject.gif
New 'File-Group' and 'File-Object' images for Format Spec.
Changed 'Boot Block' to 'Super Block'. (FF-IH_FileGroup.gif only)

./MANIFEST
./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.
H5.format.html
Copy edits
Beginning of revisions to bring the Specification up-to-date and
move it to present tense
Couple of new intro paragraphs, designed largely to offer the
user a bit more context
H5.user.html
Datatypes.html
Font correction and minor formatting changes.
H5.user.PrintGen.html
H5.user.PrintTpg.html
New files to enable creating a searchable and printable version
of the HDF5 User's Guide. These files enable the creation of a
PDF file containing the entire document. H5.user.PrintGen.html
controls the print job; H5.user.PrintTpg.html is the title page
for the PDF volume.
Changes since 19990611
----------------------
./doc/html/H5.format.html
Added documentation for opaque data types (bitfield types were
already documented but they were out of order).
./src/H5E.c
Fixed a bug with glibc2 on linux systems where `stdout' is an
extern and can't be used to initialize static data.
./src/H5T.c
./src/H5Tpkg.h
./src/H5Tpublic.h
./src/H5detect.c
Removed the `_T' from the new C9x types I just added so the
names are consistent with existing types. Besides, the fact
that something is a datatype is obvious because it starts with
H5T_NATIVE_.
./tools/h5ls.c
Added the new C9x data types. H5ls prints one of these types
only if it doesn't match one of the builtin C types.
Prints the OID for shared data types.
Fixed a formatting bug with symbolic links which was
introduced a few changes ago.
The commandline has been changed so that objects from multiple
files can be listed with a single command. Instead of
specifying a file name and an optional list of objects, each
thing to print is a file name and object concatenated. H5ls
figures out how to devide the name into a file name and object
name even when the file name part doesn't correspond to an
actual Unix file.
Old syntax: h5ls [OPTIONS] FILE [OBJECTS]
New syntax: h5ls [OPTIONS] FILE[/OBJECT] [FILE[/OBJECT]]...
Example ({X,Y} is expanded by the shell)
Old command: h5ls -d ../test/x.data dir1 dir2
New command: h5ls -d ../test/x.data/{dir1,dir2}
The filename is printed as part of the object name when full
names are requested (--full or --recursive). If people really
don't like this they can undefine a constant at the top of
h5ls.
Errors from the hdf5 library are turned off.
Commandline switches of the form `--width 80' are accepted in
addition to `--width=80'. This is more symmetric with
single-letter switches that take two forms: `-w 80' and
`-w80'.
./src/H5D.c
Added tracing instrumentation for H5Dvlen_reclaim().
./src/H5private.h
Added casts to int for the isalpha() et al macros to shut up
solaris warnings about char subscripts.
----------------------
Remove changes from CVS
./bin/release
Added a `--nocheck' switch which causes the script to not
check the contents of the MANIFEST file against CVS. This is
sometimes useful when you need to make a quick snapshot but
the MANIFEST file is not quite up to date.
./src/H5D.c
Removed warnings for unused variables
./src/H5Fprivate.h
Removed the WIN32 definition for `uint' and changed the data
type for `eof_written' from `uint' to `uintn'. Shouldn't this
really be `hbool_t'?
./src/H5Odtype.c
./src/H5T.c
./src/H5Tconv.c
./src/H5Tpkg.h
./src/H5Tpublic.h
./test/dtypes.c
./doc/html/H5.format.html
Added support for bitfields and opaque data types.
----------------------
./doc/html/H5.format.html
./src/H5HG.c
Fixed a bug in the global heap that caused H5HG_read() to
write past the end of the buffer in certain cases.
./test/big.c
The test is skipped if hdf5 was configured with
`--disable-hsizet'.
./src/H5Ofill.c
Data type conversions are implemented for the fill value.
./src/H5.c
Tracing prints one of H5P_FILE_CREATE, H5P_FILE_ACCESS,
H5P_DATASET_CREATE, H5P_DATASET_XFER, or H5P_MOUNT instead of
the more cryptic H5I_TEMPLATE_* constants.
./src/H5D.c
Removed prototype for H5D_find_name().
./src/H5I.c
The GROUP_MASK and ID_MASK are both calculated from GROUP_BITS
instead of being set by hand.
We don't use the sign bit of hid_t; all valid hid_t values are
positive so we can say things like `if ((file=H5Fopen(...))<0)'.
Changed `(int)pow(2.0,x)' to `1<<x' so we don't have to worry
about rounding.
Fixed H5I_get_type() so it doesn't always fail an assertion.
./src/H5E.c
./src/H5Epublic.h
Added minor error H5E_MOUNT
./src/H5F.c
./src/H5Fprivate.h
Added H5Fmount() and H5Funmount(). Mounting and unmounting
works as documented but some of the other things aren't
implemented yet, the biggest being current working groups
always acting on the root of the mount tree, and H5Fclose()
closing the entire tree. The rest of the stuff will be added
shortly...
./src/H5P.c
./src/H5Ppublic.h
Added the H5P_MOUNT property list but haven't implemented any
particular properties for it yet.
./src/H5Gstab.c
Hard links across files return an error instead of failing an
assertion.

distinction between C's null terminated strings and strings
which are not null terminated.
The string character set and padding method are saved to the
hdf5 file instead of using defaults.
Added conversion function from one fixed-length string type
to another.
./test/chunk.c
Fixed to work with new filter API

./bin/release
Added ./Makefile to the distribution again -- it got lost in

Added the data filter pipeline, a generalization of the
compression stuff which allows things like checksums,
encryption, compression, performance monitoring, etc. See
./doc/html/Filters.html for details -- it replaces the
Compression.html doc.
./src/H5T.c
Cleaned up debugging output.
./config/linux

for the compilers.
./src/H5G.c
./tools/h5dump.c
Fixed compiler warnings in these files and others.
./configure.in
./src/H5private.h
./test/mtime.c
Added a check for difftime() and defined HDdifftime() to do
something else on systems that don't have difftime().
----------------------
./MANIFEST
./doc/html/H5.format.html
./src/H5O.c
./src/H5Oprivate.h
./src/H5Omtime.c [NEW]
./src/H5private.h
./src/Makefile.in
Added the modification time message. If an object header has
this message then it's value is updated with the current time
whenever anything changes in the object header.
./acconfig.h
./configure.in
Alas, there seems to be no standard way to convert a string
time like 19980727122800 in UTC to a time_t since mktime()
only converts local times to time_t. So I've modified the
configuration to check for various ways of getting the time
zone information:
* Added checks for the `tm_gmtoff' field of `struct tm'.
* Added a check for the `timezone' global variable.
* Added a check for `struct timezone'.
* Added a check for BSDgettimeofday().
* Added a check for gettimeofday() although it doesn't
actually set the timezone argument on some systems.
* Added a check to see if `tm_zone' is a member of `struct tm'.
* Added a check to see if `tzname' is a global variable.
* Added a check to see if `struct tm' is defined in time.h
or sys/time.h.
It's not difficult to get the right UTC modification message
into the object header, but some systems might have problems
getting the right time back out (Irix64 is one) and those
systems will report zero for the H5G_stat_t.mtime from an
H5Gstat() call as if the mtime message isn't even present. It
will, however, continue to be updated as normal.
./src/H5G.c
./src/H5Gpublic.h
The H5G_stat_t struct now contains an `mtime' field which will
hold the object modification time. If the object has no
object modification time then the `mtime' will be initialized
to zero.
Fixed a bug in H5G_stat() that caused the `objno' field of the
H5G_stat_t to be set incorrectly on some machines.
./src/H5D.c
Writing to external datasets fail if the hdf5 file is not open
for writing.
A modification time message is added to the dataset object
header when it's created and H5O_touch() is called from
H5D_write() to update that message.
./src/H5T.c
Fixed a bug in H5Tget_member_dims() that caused a segmentation
fault if one of the output array arguments was the null
pointer.
Relaxed the member dimension checking in H5Tinsert_array() so
it can also be used for scalar members.
./test/Makefile.in
Added additional file names to the `mostlyclean' target.
./tools/h5dump.c
./tools/h5tools.h
Increased the temporary buffer size to 1MB.
Added support for printing compound data types with array
members.
When printing H5T_NATIVE_CHAR and H5T_NATIVE_UCHAR we escape
double quote characters.
./tools/h5ls.c
Changed the output format a little because we were starting to
get too much info to fit on a line. Without `--verbose' each
object occupies one line of output. Otherwise, additional
information is printed below the object name: object file
address, comment, and modification time. If `--dump' is given
then the data is printed after the other information.
./test/cmpd_dset.c
Changed the way the dataset is initialized to be more uniform.

./src/H5Olayout.c
./src/H5Osdspace.c
./src/H5Oshared.c
Added version numbers to some object header messages so we can
update them easier in the future. The library currently just
gives up if the version numbers don't match, but in the future
the library could handle multiple versions of a message.
./test/testhdf5.c
Removed an argument from the H5version() call that I missed
last time.
----------------------
./doc/html/H5.format.html
./src/H5F.c
./src/H5Gprivate.h
./src/H5Oshared.c
Added file alignment fields: the boot block has an extra
reserved address field. The symbol table entry scratch pad
space was reduced from 24 bytes to 16 bytes. The index
permutation was moved earlier in the data type message for
compound data types and extra padding was added. Four bytes
of padding was added to the shared message format.

./src/H5Oshared.c
./src/H5HG.c
./src/H5HGprivate.h
Added padding fields in symbol table entries, attribute
messages, shared messages, and global heap objects to insure
that things are aligned on 8-byte boundaries in the file, and
thus in memory. Otherwise some little endian machines
complain (DEC Alpha) during encoding/decoding of file meta
data. I chose to add alignment to the file rather than
rewriting the ENCODE/DECODE macros for the little endian case.
Completely rewrote the section on attribute messages.
More alignment stuff will follow.
./src/H5detect.c
Fixed a typo `nd'->`dn'
./test/dtypes.c
Commented out conversion tests to/from `long double' on
machines where it's the same size as `double' to get rid of
compiler warnings.
./doc/html/Big.html
Fixed a couple typos.
