New documentation for chunking. It's not quite complete but
it gives a pretty good idea of some of the issues affecting
performance.
Changed H5Sget_space_type to H5Sget_simple_extent_type.
Changed H5Sget_simple_extent_type FAIL return value to
H5S_NO_CLASS.
RM_H5F.html
H5Fflush. Corrected function name in sytax line, which
had read H5Fis_hdf.
RM_H5G.html
Removed discussion of "current working group" and associated
information from the introductory discussion.
H5Gset, H5Gpush, H5Gpop
Removed these functions.
H5Gunlink, H5Gmove
Removed the "not yet implemented" notations from
these functions.
Revised and extended hyperslab selection image.
Added section "Selecting a union of hyperslabs."
IH_map*.gif (6 new files)
New images for "Intro to HDF5."
As a composite, these replace H5.intro.datamap.gif.
H5.intro.datamap.gif
Removed. Replaced by the composite IH_map*.gif.
RM_H5RA.html (new file)
RM_H5Front.html

Ragged.html
H5.user.html

Changed links to RM_H5R.html to RM_H5RA.html.
RM_H5R.html
Removed. Replaced by RM_H5RA.html.
----------------------
./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.

such systems (e.g., Irix64) will report an mtime
value of 0 (zero)."
Corrected successful return value.

Changed the values of the H5T_str_t type in order to make a
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
----------------------
./config/solaris2.5
Hopefully set up now so it honors the CC and CFLAGS variables
and understands solaris cc flags.
./test/big.c
Checks to see if creating lots of large sparse files exceeds
the user disk quota and skips the test. It also checks that
we can actually open ~64 files at once.
./doc/html/Files.html
./src/H5A.c
./src/H5Aprivate.h
./src/H5F.c
./src/H5Fpublic.h
Added the H5Fflush() function which takes any object as an
argument as long as the object is in some way associated with
a file. This required an H5A_entof()
./src/H5.c
./src/H5Flow.c
The `%a' format of HDfprintf() now allows a field width and
justification flag etc, like the other formats. The old
H5F_addr_print() was recoded to call HDfprintf() instead of
vice versa.
----------------------
./MANIFEST
Replaced Compression.html with Filters.html
./doc/html/Filters.html
./src/H5Ocomp.c
./src/H5P.c
./src/H5Ppublic.h
./src/H5Z.c
./src/H5Zprivate.h
Added two extra arguments to H5Pget_filter() in order to
retrieve the filter name. The name is the name registered for
the filter with H5Zregister(), but if the dataset creation
property originally came from an existing file then the name
is that which is stored in the file.
./tools/h5ls.c
The `-v' option now prints the names of the filters.
./src/H5B.c
./src/H5Fistore.c
./src/H5O.c
./src/H5Oefl.c
./src/H5Oprivate.h

./src/H5MMprivate.h
H5MM_malloc(0) and H5MM_calloc(0) actually allocate a single
byte in order to be sure that we get a valid pointer.
./src/H5S.c
./src/H5Sselect.c
Fixed pointer->integer conversions in error return values in
three places.
----------------------

Added ./Makefile to the distribution again -- it got lost in
the changes last week although it isn't all that important a

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/H5A.c
./src/H5Apublic.h
./test/tattr.c
Switched the order of the second and third argument of
H5Aget_name() to make it consistent with other functions that
take buffers and buffer sizes.
./src/H5G.c
./src/H5Gpublic.h
./src/H5Gprivate.h
The H5Gget_comment() function returns the size of the comment
including the null terminator. If the object has no comment
then zero is returned. If an error occurs then a negative
value is returned.
./MANIFEST
./tools/Makefile.in
./tools/h5tools.h [NEW]
./tools/h5dump.c [NEW]
Created a library for printing values of datasets in a way
that looks nice. It's not done yet, but I needed it for
debugging the contents of files from Jim Reus.
./tools/h5ls.c
Added the `-d' and `--dump' options which cause the contents
of a dataset to be printed. Added `-w N' and `--width=N'
options to control how wide the raw data output should be. If
you want single-column output then say `-w1'.
Printing dataset values can now handle datasets of any integer
or floating point atomic type. As a special case, integers
which are one byte wide are treated a character strings for
now.
Sample output:
$ h5ls --dump --width=60 banana.hdf
ARCHIVE 0:0:0:744 Dataset {52/Inf}
Data:
(0) "U struct complex { double R; double I; };\012V"
(43) " double;\012"
U 0:0:0:2500 Dataset {256/512}
Data: printing of compound data types is not implemented yet
V 0:0:0:3928 Dataset {256/512}
Data:
(0) 0, 0.015625, 0.03125, 0.046875, 0.0625,
(5) 0.078125, 0.09375, 0.109375, 0.125, 0.140625,
(10) 0.15625, 0.171875, 0.1875, 0.203125, 0.21875,

...
----------------------
./src/H5Gpublic.h
./src/H5Gprivate.h
./src/H5G.c
./test/dsets.c
./doc/html/Groups.html
Added the H5Gset_comment() and H5Gget_comment() functions
described in an earlier e-mail.
./src/H5.c
Fixed a bug in the tracing code that caused certain data space
enum types to not be printed. Nested case statements can get
confusing to the eyes!
./tools/h5ls.c
Prints the first 50 bytes or so of object comments.
----------------------

./src/H5Odtype.c
./src/H5Oefl.c
./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.
----------------------
./bin/release
The archive names have only three parts to a version number.
Instead of `hdf5-1.2.3d.tar.gz' they will be named like
`hdf5-1.2.3.tar.gz'.
./src/H5public.h
./src/H5.c
Dropped the patch level from the version number. The version
number is now a major number, a minor number, and a release
number.
./doc/html/Version.html
Updated to get rid of patch numbers.
./tools/h5repart.c
Added a `-V' flag like for `h5ls' that prints the version number.
----------------------
./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.
----------------------
./doc/html/H5.format.html
./src/H5Gent.c
./src/H5Gprivate.h
./src/H5Oattr.c
./src/H5Oprivate.h
./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.
