h5dump bug 701. Symptom: The creation of a hardlink pointing to the root group "/" causes h5dump to display it as a link pointing to itself.
Cure: the root group was not being inserted in the table that keeps track of object names and links.
Added a test for this in the test generation program, the creation of a hardlink to the root
Description:
the original code that showed a name for HARDLINK was reassigning that name to a name
made in the dump traversal (made by concatenation by nested objects)
Solution:
removed this reassigmnet
now the name showed after HARDLINK is always the first name found for that object
(this object is printed once interely; subsequent printings show the word HARDLINK
and the first name )
Platforms tested:
linux
AIX
solaris
Misc. update:
bug fix
Description:
the indentation was not made properly for nested objects when printing array indices
Solution:
added the indentation to h5tools_simple_prefix function
Platforms tested:
linux
AIX
solaris
Misc. update:
h5dump new feature, bug fix
Description:
added the dump of unmamed types to the file contents
fixed a bug in the type array, it was printing invalid characters with the array indices option on
Solution:
Platforms tested:
linux
AIX
solaris
Misc. update:
dumper new features
Description:
1) added options for not printing : datasets, groups, datatypes, links
2) added a section for the user block
3) in the traversal routine, added the printing of an arrow for soft links and t
he word HARDLINK for hardlinks
the print of the file contents is made during traversal , instead of at the e
nd of it (this is helpful
for very large files, where the wait time can be very long)
4) changed the description of the fill value properties
5) added a colon after the printing of the array indices
Solution:
Platforms tested:
linux
AIX
solaris
Misc. update:
h5dump new version
Description:
added the changes already made for 1.6
support for dumping of
1) filters
2) storage layout
3) fill value
4) comments
5) superblock
6) file contents
7) array indices
Solution:
Platforms tested:
linux
solaris
AIX
Misc. update:
macros in the dumper. this was basically adding a space after most of the '}'.
there are some places that don't have the space because those '}' were not printed
by the end_obj macro
New feature
Solution:
Added some new new tests to show that paths involving HARDLINKS
and paths involving SOFTLINKS convert existing objects from H5 to
H4 the same way that paths involving no links does.
Platform tested:
Solaris2.5
----------------------
./INSTALL
Added warning that enabling debugging code can adversely
affect performance even when the debugging isn't turned on at
run-time. Performance testing shows that under certain
circumstances (like data type conversions of compound types)
the H5_timer functions, although only a few lines each,
contribute a fairly large percent to the execution time.
./src/H5T.c
./src/H5Tpkg.h
./src/H5Tpublic.h
Improved the H5Tunregister() function to make unregistering
more flexible. It takes the same arguments as H5Tregister()
but also accepts wild cards. All conversion functions that
match the H5Tunregister() search criteria are removed from the
global type conversion table.
The H5Tregister_hard() and H5Tregister_soft() were combined
into a single function called H5Tregister() which is the
counterpart to H5Tunregister(). A new `persistence' argument
was added to differentiate between the two types of conversion
functions.
The application is allowed to register a hard conversion
function for the no-op conversion path although the library
isn't obligated to call it (it usually does). This is mostly
for completeness, but the application might use it to help
determine if the raw data pipeline was able to use the
optimized path for the case when no type conversion is
necessary. The library doesn't allow this path to be
unregistered although the application can redefine it as often
as it likes.
Fixed the type conversion tables in preparation for MT-safety
and to fix previosly-known design bugs wrt. unregistering
conversion functions or changing the C function associated
with a conversion path. The MT-safety stuff is documented in a
separate white paper.
Increased the conversion function debugging name from 9
characters to 31 characters so the output can be more
descriptive.
Moved conversion path statistics from the H5T_cdata_t member
into the conversion path itself. This makes H5T_cdata_t
contain only application-visible data structures.
./src/H5A.c
./src/H5D.c
./src/H5Ofill.c
./src/H5P.c
./src/H5T.c
Improved the way type conversion functions are called so the
caller doesn't have to check for data type debugging and
increment type conversion timers and statistics.
Changed check for no-op conversion since it is now
application-definable and there may even be more than one
definition at a time in a multi-threaded application (one
thread might be using the no-op conversion path when some
other thread changes its definition -- the first thread still
sees the original defintion until it's done with the
operation).
./doc/html/Datatypes.html
Updated the user guide to reflect the changes to data type
conversion registration functions.
./bin/trace
./src/H5.c
Added tracing support for the new H5T_pers_t data type.
./test/dtypes.c
Added printf to display alignment value if non-aligned data
types are being tested.
./test/h5test.c
Modified the H5Tunregister() calls to use the new
arguments. All 94 of those calls can be replaced by a single
call to the new H5Tunregister() function.
./src/H5.c
Added HAVE_GETTIMEOFDAY around an auto variable and
initialized the elapsed time to zero when gettimeofday() is
not available.
./src/H5F.c
./src/H5Fprivate.h
./src/H5P.c
Added an H5*_init() functions which do the same thing as
H5*_init_interface() but can be called from other packages and
don't do anything if the interface is already initialized.
This fixes a couple memory leaks in applications that
repeatedly close and open the library with H5close().
./src/H5Tconv.c
Optimized some data alignment code in the hardware conversion
functions.
Hardware conversions accumulate statistics about source and
destination data alignment and print that information when the
conversion function is unregistered (usually when the
application exits) if data type debugging is compiled into the
library and enabled at run-time.
The conversion caching was cleaned up for the compound data
type conversion function. It now caches conversion paths in a
manner that will be MT-safe and is much simpler than the old
method. Also cleaned up some array index maps.
./src/H5detect.c
Fixd mispelling of alingemnt.
./src/H5private.h
Changed `TRUE' to `1' in assignment to interface_initialize_g
in FUNC_ENTER macro definition.
./tools/testh5dump.sh
Completely rewritten to make it shorter, better documented,
and conforming to most of the other test outputs.
The comparison of the actual output with the expected output
is insensitive to differences in white space. The test now
passes for the first time on Linux where the output width
wasn't as expected but the output was otherwise correct.
