Bug fix
Description:
The output of floating point dumps wasn't necessarily standard.
The h5ls utility does it in a better way.
Solution:
Changed the output parameters from %g to %1.*g and added the
appropriate FLT_DIG/DBL_DIG parameter for the `*' in the above.
Platforms tested:
Linux
Bug fix
Description:
[Most] SGIs failed on dumping VL data during the daily tests they
seem to be initializing variables differently, exposing a bug in dumping
datasets with scalar dataspaces.
Also, clean up code to get rid of compiler warnings.
Solution:
Initilialize variable correctly.
Platforms tested:
SGI IRIX 6.5 (paz)
Bug fix.
Description:
VL datatype dumping was not working correctly on most machines because
the "native" version of the variable-length type wasn't being generated
for the printing process.
Re-enabled VL dumping test
Solution:
Generate "native" version of the VL datatype to read in for printing,
also some code cleanup in the VL dumping algorithm.
Platforms tested:
FreeBSD 4.1.1 (hawkwind) & Solaris 2.6 (baldric)
Feature
Description:
Variable length data dumping for simple (i.e., either SCALAR or
1-Dim array variable length datatypes) should work. Added to the
tests...
Platforms tested:
Linux
Recoding of VL dumping.
Description:
I'm using hyperslabs to select the variable length data. I don't
have any tests which I've checked in just yet. I'll create those
later.
Platforms tested:
Linux
new feature
Description:
h5tools.c:
Created h5tools_init() and h5tools_close() for the initialization
of the h5tools library and closing of it. With this, the rawdatastream
and other internal structures can be initialized properly.
h5tools.h:
added prototypes for h5tools_init and h5tools_close.
h5dump.c:
h5ls.c:
Added the calls for h5tools_init() and h5tools_close().
Platforms tested:
IRIX64 -64 parallel and Linux
* 2000-10-31 Robb Matzke <matzke@llnl.gov> (h5dump_sprint)
The whitespace added for
indentation after the line-feed kludge is performed only if a
line-feed was actually inserted. This fixes funny-looking h5ls
output that had ` %s' sequences appearing in nested compound
datatypes.
Also added a prominent warning in the code to indicate that when a
line-feed is inserted into the string that column number
calculations will be incorrect and object indices will be missing.
Feature
Description:
Allow dumping of variable length records. This is a first-time
stab at this. It doesn't break any tests on my Linux box and it
does output the variable length data, but it might look ugly (it
doesn't handle new-lines as of yet)...I'm open to suggestions on
what should be done next, what new features to add/remove...
Platforms tested:
Linux
Bug fix
Description:
In the h5dump_fixtype function, when users created a COMPOUND
datatype, the alignment would be off somewhat.
Solution:
The alignment was being set after insertion. I changed this code:
for (i = 0, offset = 0; i < nmembs; i++) {
H5Tinsert_array(m_type, name[i], offset, ndims[i], dims + i * 4,
NULL, memb[i]);
for (j = 0, nelmts = 1; j < ndims[i]; j++)
nelmts *= dims[i * 4 + j];
offset = ALIGN(offset, H5Tget_size(memb[i])) +
nelmts * H5Tget_size(memb[i]);
}
to:
for (i = 0, offset = 0; i < nmembs; i++) {
if (offset)
offset = ALIGN(offset, H5Tget_size(memb[i]));
H5Tinsert_array(m_type, name[i], offset, ndims[i], dims + i * 4,
NULL, memb[i]);
for (j = 0, nelmts = 1; j < ndims[i]; j++)
nelmts *= dims[i * 4 + j];
offset += nelmts * H5Tget_size(memb[i]);
}
The alignment is now calculated before the insertion.
Platforms tested:
Solaris, Linux
New Feature
Description:
Add -o option to h5dumper. It displays the raw data of datasets to a
separate output file.
Add a feature to h5tools library that it uses the FILE *rawdatastream
as the stream for the display of datasets raw data.
Solution:
Define an "extern FILE *rawdatastream" in h5tools.h
and declare it in h5tools.c. This way, it would work
even if an application does not explicitely declare it.
Tried to initialized it to stdout as
FILE *rawdatastream = stdout;
but Linux gcc rejected it though all other platforms+compilers
accepted it fine. For now, put in a kludge to set it right
before it is used. Need a safer way to initialize it.
Platforms tested:
arabica, eirene, modi4 -64.
Added the Stream Virtual File Driver to the list of drivers
used for trying to open a file via h5dump_fopen().
Description:
The Stream VFD was added at bottom of the driver list for h5dump_fopen().
If no driver succeeded to open a file given by its filename
the Stream VFD would try to do so by parsing the filename as an
'hostname:port' argument, open a socket to that address and read
read the file.
This feature can be used to h5ls/h5dump streamed files.
Platforms:
All platforms (also between heterogenous).
1. The `driver' table is initialized only once, making it faster and
leaking less memory.
2. The returned driver name is set to the empty string on failure.
3. Added an argument so the function cannot overwrite the end of the
drivername return value.
4. Avoids core dump when assigning driver name to return value if the
file could not be opened by any driver.
5. Changed name of function to h5dump_fopen() to follow the naming
scheme for this source file.
6. Reindented according to hdf5 code standard.
7. Added `const' qualifiers to read-only formals.
8. Removed duplicate forward declaration.
Reindented some parts of these source files that had very odd indentation
(some lines had no indentation while others had 3x what they should).
Fixed calls to H5ToolsFopen() function.
library for it(H5ToolsFopen-takes a filename and a char ptr if you want the name of the driver)
added the function to h5tools.c, a header to h5tools.h and changed h5ls.c and h5dump.c to use the new
functions
from h5tools.h just got rid of a prototype for copy_atmoic_char which was never used
in the h5tools.c i removed the copy_atomic_char, all the display_*_data, where the * is numeric, string
or compound, the print_data, h5dump_attr. also removed a block of codfe that was surrounded by #if 0
Prints the subrelease name also.
** tools/h5tools.c
Fixed indentation problems in the first half of the file.
Changed conditional compilation style from `/*...*/' to use
#if 0/#endif in the first half of this file.
Removed some extra parentheses to make expressions more readable.
now the dump structure contains 2 extra members that tell how to format the
data for the dataset regions(blocks and pts).
had to give h5ls values for these
in h5dump.c just initialized the values for the formatting struct.
in h5tools.c made some changes in the printing area to get the dump output to
look closer to what we wanted. the strings are currently not printing correctly.
also removed the program type variable from here.
Added -V option for displaying version information.
h5tools.c:
Added print_version routine to display version information.
h5tools.h:
Added print_version prototype.
with out the square braces. also the formatting for the compound types
in the dataset part section has been corrected.
still need to update the expected outputs so there will be some errors until
I get that all checked in...
so i moved the dumper stuff out to the libary. Had to change some functions
in h5findshd so they would stop using globals that shouldn't be defined in the
lib. I will remove the globals next. also the h5findshd.c has an extra member
to the struct for that objects in the table so i added that into the appropriate place.
the dumper is working ok now but the h5toh4 is still broken.
----------------------
./src/H5FDcore.c
Includes private headers instead of public in order to use the
`UNUSED' macro.
./src/H5FDpublic.h
Includes H5public.h just in case.
./src/H5P.c
Removed two unused variables in H5P_copy()
./src/H5FDgass.h
Fixed a C++ comment after a `#endif'
./src/Makefile.in
The H5FDgass.h file is public and must be installed in order for
applications to be able to use HDF5.
./tools/h5tools.c
Removed an unused variable.
----------------------
./src/H5public.h
We undefine a bunch of things that could get redefined in the config
file because some customers have applications that include headers
from multiple packages, all of which might be using autoconf.
Include <stdint.h> for the C9x types.
./test/h5test.h
More flushing of stdout for when testing is redirected down a pipe.
./tools/h5ls.c
Added a `-S' or `--simple' switch which causes the output to be
simplified somewhat for easier parsing by other scripts. For instance,
characters are escaped using a very simple mechanism instead of C's
more complicated backslash notation, data doesn't have `{}' or `[]'
characters interspersed for compound and array types, and data is
printed with exactly one element per line. This switch is now used by
an HDF5-to-HTML CGI script being developed for the DMF people.
./tools/h5tools.c
./tools/h5tools.h
The repeat threshold which controls how strings are printed when a
character repeats a bunch of times is now settable at runtime instead
of compile time. The default is to show all characters, like
"abceeeeeeeeeeeeeeeeeeeeeeeeeeeeeefgh"
But if you set it to something like 5 then any sequence of 5 or more
characters is replaced by something shorter, like:
"abc" 'e'x30 "fgh" or
Added an `str_locale' property which describes how to escape special
characters in strings. The default is C-like escapes but an
alternative is ESCAPE_HTML which replaces all non-alphanumeric
characters with a 3-character HTML escape of the form `%XX'
Fixed a bug where empty strings didn't even have the quote characters
printed. Now empty strings show up as `""' instead of absolutely
nothing.
Added a `per_line' property which controls the maximum number of
elements which will appear per line of output. The default is infinity
but in practice the right margin causes line breaks. By setting the
`per_line' value to one and the right margin to a very large value one
can achieve output with exactly one element per line.
