#define H5G_PACKAGE /*suppress error message about including H5Gpkg.h*/
|
[svn-r6] Added the next layer of symbol table functions. Given a symbol table
name, they operate to query or modify the corresponding symbol table entry.
They don't understand directory hierarchies (that's the next layer up).
Since the object header stuff isn't done yet, they call four stub functions
that all return failure:
not_implemented_yet__create_object_header()
not_implemented_yet__insert_symtab_message()
not_implemented_yet__get_symtab_message()
not_implemented_yet__update_symtab_message()
The interface is:
haddr_t H5G_new (file, initial_heap_size)
Creates a new symbol table.
haddr_t H5G_find (file, symtab_addr, symbol_name, *entry)
Returns a symbol table entry given the name.
herr_t H5G_modify (file, symtab_addr, symbol_name, *entry)
Modifies the symbol table entry for the specified name.
herr_t H5G_insert (file, symtab_addr, symbol_name, *entry)
Inserts a new name and symbol table entry pair.
intn H5G_list (file, symtab_addr, maxentries, names[], entries[])
Returns a list of all names and symbol table entries.

[svn-r139] ./src/*.[ch]
Removed the interface initialization argument from
FUNC_ENTER() and made it a locally-defined preprocessor
symbol, INTERFACE_INIT.
Changed `offset' to `address' and `length' to `size' in
documentation so it's more consistent. `Offset' still appears
occassionally when it refers to a byte offset within some
other data structure.
Moved interface termination function prototypes from public
header files to .c files and made them static.
./src/H5.c
./src/H5public.h
Added H5init() because it's possible that the predefined data
types are not initialized. This happens only if the first
call to the hdf5 library passes a predefined data type symbol
as an argument. There should be some way to fix this...
./src/H5A.c
./src/H5Aprivate.h
./src/H5Apublic.h
The free_func returns SUCCEED or FAIL, although the return
value is ignored by H5A. This is so we can use the various
H5*_close() functions to free things.
H5Ainc_ref() and H5Adec_ref() are no longer public. Many of
the other atom functions should also be made private, but I'll
save that for later...
Added additional template groups called H5_TEMPLATE_0 through
H5_TEMPLATE_7 that are used by the various template
subclasses.
Increased the number of bits used for atom groups to prevent
negative atoms.
./src/H5AC.c
./src/H5ACprivate.h
Changed H5AC_new() to H5AC_create() to make names more consistent.
./src/H5B.c
./src/H5Bprivate.h
Changed H5B_new() to H5B_create() to make names more consistent.
./src/H5C.c
./src/H5Cprivate.h
./src/H5Cpublic.h
Now supports multiple subclasses of templates, although it's
done with big switch statements. The default values for
templates are defined in the source file to which that
template belongs. This got rid of lots of needless
preprocessor constants.
Added H5Ccreate() to create a new template. Changed
H5C_release() to H5Cclose() to make the naming more
consistent.
./src/H5D.c
./src/H5Dprivate.h
./src/H5Dpublic.h
Enhanced to use the new dataset interface, and uses the enhanced
data type and data space interfaces, which haven't been
completely implemented. The dataset interface doesn't handle
non-contiguous storage, compression, or data type and space
conversions yet.
./src/H5F.c
./src/H5Fprivate.h
./src/H5Fpublic.h
Removed H5Fflush() since just calls H5F_flush(), which doesn't
do what the user would probably think it does, namely, flush
everything. It only flushes those things sitting in the H5AC
cache and the boot block.
Changed the `file_create_parms' field of H5F_low_t to just
`create_parms' since the `file' part is obvious.
./src/H5Fistore.c
Added some support for external files. Mostly just in the
file format and not supported much by the library yet. I need
to finish some dataset functions first.
Changed H5F_istore_new() to H5F_istore_create() to make names
more uniform across packages.
./src/H5Flow.c
Flushing a file causes the file to be physically extended to
the logical eof. This prevents H5F_open() from thinking a
file has been truncated. Most of the time the file will
already be that large, and when it isn't Unix will often just
allocate the final block anyway.
./src/H5G.c
./src/H5Gent.c
./src/H5Gnode.c
./src/H5Gpkg.h
./src/H5Gprivate.h
./src/H5Gstab.c
Removed H5G_basename()
Removed (temporarily) data type information from symbol table
entries and renamed H5G_CACHED_SDATA to H5G_CACHED_SDSPACE to
reflect that it's a simple data space and has nothing to do
with raw data.
Changed H5G_node_new() to H5G_node_create() and H5G_stab_new()
to H5G_stab_create() to make names more uniform across
packages.
Fixed an undefined address bug that happens when H5G_node_debug()
program doesn't pass enough info to H5G_node_load().
./src/H5H.c
./src/H5Hprivate.h
Changed H5H_new() to H5H_create() to make the names more
uniform across packages.
./src/H5M.c
./src/H5Mprivate.h
./src/H5Mpublic.h
Nulled all the create functions. Most of the other callbacks
are to public functions. Removed H5Mcreate().
Changed hobjtype_t to group_t since it has to be the same
thing anyway.
./src/H5O.c
./src/H5Oprivate.h
./src/H5Osdim.c
./src/H5Osdtyp.c
Changed H5O_SIM_DIM to H5O_SDSPACE (simple data space) since
`simple data space' is its official name, not `simple
dimensions'. Will eventually add H5O_CDSPACE for comples data
spaces. Changed _sim_dim_ to _dspace_.
Replaced H5O_SIM_DTYPE and the compound data type messages
with a single H5O_DTYPE message. Changed _sim_dtype_ to _dtype_.
Changed H5O_STD_STORE to H5O_CSTORE (contiguous storage) since
contiguous storage is not necessarily standard. Changed
_std_store_ to _cstore_ in H5Ocstore.c
Added the H5O_EFL (external file list) message.
Changed H5O_new() to H5O_create() to make names more uniform
across packages.
./src/H5Oefl.c NEW
External file list message for specifying which non-hdf5 files
contain raw data for a dataset.
./src/H5P.c
./src/H5Pprivate.h
./src/H5Ppublic.h
Renamed and moved data structures to make the names conform to
our naming scheme.
./src/H5T.c
./src/H5Tprivate.h
./src/H5Tpublic.h
./src/H5Tpkg.h NEW
Data structures redesigned to be more flexible. The interface
was redesigned to make it more regular and to make some names
more uniform across packages.
./src/H5detect.c
Output was changed to produce a file that conforms to the hdf5
coding standard.
./src/Makefile.in
Generates H5Tinit.c by running H5detect.
./src/debug.c
Moved command argument processing.

[svn-r139] ./src/*.[ch]
Removed the interface initialization argument from
FUNC_ENTER() and made it a locally-defined preprocessor
symbol, INTERFACE_INIT.
Changed `offset' to `address' and `length' to `size' in
documentation so it's more consistent. `Offset' still appears
occassionally when it refers to a byte offset within some
other data structure.
Moved interface termination function prototypes from public
header files to .c files and made them static.
./src/H5.c
./src/H5public.h
Added H5init() because it's possible that the predefined data
types are not initialized. This happens only if the first
call to the hdf5 library passes a predefined data type symbol
as an argument. There should be some way to fix this...
./src/H5A.c
./src/H5Aprivate.h
./src/H5Apublic.h
The free_func returns SUCCEED or FAIL, although the return
value is ignored by H5A. This is so we can use the various
H5*_close() functions to free things.
H5Ainc_ref() and H5Adec_ref() are no longer public. Many of
the other atom functions should also be made private, but I'll
save that for later...
Added additional template groups called H5_TEMPLATE_0 through
H5_TEMPLATE_7 that are used by the various template
subclasses.
Increased the number of bits used for atom groups to prevent
negative atoms.
./src/H5AC.c
./src/H5ACprivate.h
Changed H5AC_new() to H5AC_create() to make names more consistent.
./src/H5B.c
./src/H5Bprivate.h
Changed H5B_new() to H5B_create() to make names more consistent.
./src/H5C.c
./src/H5Cprivate.h
./src/H5Cpublic.h
Now supports multiple subclasses of templates, although it's
done with big switch statements. The default values for
templates are defined in the source file to which that
template belongs. This got rid of lots of needless
preprocessor constants.
Added H5Ccreate() to create a new template. Changed
H5C_release() to H5Cclose() to make the naming more
consistent.
./src/H5D.c
./src/H5Dprivate.h
./src/H5Dpublic.h
Enhanced to use the new dataset interface, and uses the enhanced
data type and data space interfaces, which haven't been
completely implemented. The dataset interface doesn't handle
non-contiguous storage, compression, or data type and space
conversions yet.
./src/H5F.c
./src/H5Fprivate.h
./src/H5Fpublic.h
Removed H5Fflush() since just calls H5F_flush(), which doesn't
do what the user would probably think it does, namely, flush
everything. It only flushes those things sitting in the H5AC
cache and the boot block.
Changed the `file_create_parms' field of H5F_low_t to just
`create_parms' since the `file' part is obvious.
./src/H5Fistore.c
Added some support for external files. Mostly just in the
file format and not supported much by the library yet. I need
to finish some dataset functions first.
Changed H5F_istore_new() to H5F_istore_create() to make names
more uniform across packages.
./src/H5Flow.c
Flushing a file causes the file to be physically extended to
the logical eof. This prevents H5F_open() from thinking a
file has been truncated. Most of the time the file will
already be that large, and when it isn't Unix will often just
allocate the final block anyway.
./src/H5G.c
./src/H5Gent.c
./src/H5Gnode.c
./src/H5Gpkg.h
./src/H5Gprivate.h
./src/H5Gstab.c
Removed H5G_basename()
Removed (temporarily) data type information from symbol table
entries and renamed H5G_CACHED_SDATA to H5G_CACHED_SDSPACE to
reflect that it's a simple data space and has nothing to do
with raw data.
Changed H5G_node_new() to H5G_node_create() and H5G_stab_new()
to H5G_stab_create() to make names more uniform across
packages.
Fixed an undefined address bug that happens when H5G_node_debug()
program doesn't pass enough info to H5G_node_load().
./src/H5H.c
./src/H5Hprivate.h
Changed H5H_new() to H5H_create() to make the names more
uniform across packages.
./src/H5M.c
./src/H5Mprivate.h
./src/H5Mpublic.h
Nulled all the create functions. Most of the other callbacks
are to public functions. Removed H5Mcreate().
Changed hobjtype_t to group_t since it has to be the same
thing anyway.
./src/H5O.c
./src/H5Oprivate.h
./src/H5Osdim.c
./src/H5Osdtyp.c
Changed H5O_SIM_DIM to H5O_SDSPACE (simple data space) since
`simple data space' is its official name, not `simple
dimensions'. Will eventually add H5O_CDSPACE for comples data
spaces. Changed _sim_dim_ to _dspace_.
Replaced H5O_SIM_DTYPE and the compound data type messages
with a single H5O_DTYPE message. Changed _sim_dtype_ to _dtype_.
Changed H5O_STD_STORE to H5O_CSTORE (contiguous storage) since
contiguous storage is not necessarily standard. Changed
_std_store_ to _cstore_ in H5Ocstore.c
Added the H5O_EFL (external file list) message.
Changed H5O_new() to H5O_create() to make names more uniform
across packages.
./src/H5Oefl.c NEW
External file list message for specifying which non-hdf5 files
contain raw data for a dataset.
./src/H5P.c
./src/H5Pprivate.h
./src/H5Ppublic.h
Renamed and moved data structures to make the names conform to
our naming scheme.
./src/H5T.c
./src/H5Tprivate.h
./src/H5Tpublic.h
./src/H5Tpkg.h NEW
Data structures redesigned to be more flexible. The interface
was redesigned to make it more regular and to make some names
more uniform across packages.
./src/H5detect.c
Output was changed to produce a file that conforms to the hdf5
coding standard.
./src/Makefile.in
Generates H5Tinit.c by running H5detect.
./src/debug.c
Moved command argument processing.

[svn-r139] ./src/*.[ch]
Removed the interface initialization argument from
FUNC_ENTER() and made it a locally-defined preprocessor
symbol, INTERFACE_INIT.
Changed `offset' to `address' and `length' to `size' in
documentation so it's more consistent. `Offset' still appears
occassionally when it refers to a byte offset within some
other data structure.
Moved interface termination function prototypes from public
header files to .c files and made them static.
./src/H5.c
./src/H5public.h
Added H5init() because it's possible that the predefined data
types are not initialized. This happens only if the first
call to the hdf5 library passes a predefined data type symbol
as an argument. There should be some way to fix this...
./src/H5A.c
./src/H5Aprivate.h
./src/H5Apublic.h
The free_func returns SUCCEED or FAIL, although the return
value is ignored by H5A. This is so we can use the various
H5*_close() functions to free things.
H5Ainc_ref() and H5Adec_ref() are no longer public. Many of
the other atom functions should also be made private, but I'll
save that for later...
Added additional template groups called H5_TEMPLATE_0 through
H5_TEMPLATE_7 that are used by the various template
subclasses.
Increased the number of bits used for atom groups to prevent
negative atoms.
./src/H5AC.c
./src/H5ACprivate.h
Changed H5AC_new() to H5AC_create() to make names more consistent.
./src/H5B.c
./src/H5Bprivate.h
Changed H5B_new() to H5B_create() to make names more consistent.
./src/H5C.c
./src/H5Cprivate.h
./src/H5Cpublic.h
Now supports multiple subclasses of templates, although it's
done with big switch statements. The default values for
templates are defined in the source file to which that
template belongs. This got rid of lots of needless
preprocessor constants.
Added H5Ccreate() to create a new template. Changed
H5C_release() to H5Cclose() to make the naming more
consistent.
./src/H5D.c
./src/H5Dprivate.h
./src/H5Dpublic.h
Enhanced to use the new dataset interface, and uses the enhanced
data type and data space interfaces, which haven't been
completely implemented. The dataset interface doesn't handle
non-contiguous storage, compression, or data type and space
conversions yet.
./src/H5F.c
./src/H5Fprivate.h
./src/H5Fpublic.h
Removed H5Fflush() since just calls H5F_flush(), which doesn't
do what the user would probably think it does, namely, flush
everything. It only flushes those things sitting in the H5AC
cache and the boot block.
Changed the `file_create_parms' field of H5F_low_t to just
`create_parms' since the `file' part is obvious.
./src/H5Fistore.c
Added some support for external files. Mostly just in the
file format and not supported much by the library yet. I need
to finish some dataset functions first.
Changed H5F_istore_new() to H5F_istore_create() to make names
more uniform across packages.
./src/H5Flow.c
Flushing a file causes the file to be physically extended to
the logical eof. This prevents H5F_open() from thinking a
file has been truncated. Most of the time the file will
already be that large, and when it isn't Unix will often just
allocate the final block anyway.
./src/H5G.c
./src/H5Gent.c
./src/H5Gnode.c
./src/H5Gpkg.h
./src/H5Gprivate.h
./src/H5Gstab.c
Removed H5G_basename()
Removed (temporarily) data type information from symbol table
entries and renamed H5G_CACHED_SDATA to H5G_CACHED_SDSPACE to
reflect that it's a simple data space and has nothing to do
with raw data.
Changed H5G_node_new() to H5G_node_create() and H5G_stab_new()
to H5G_stab_create() to make names more uniform across
packages.
Fixed an undefined address bug that happens when H5G_node_debug()
program doesn't pass enough info to H5G_node_load().
./src/H5H.c
./src/H5Hprivate.h
Changed H5H_new() to H5H_create() to make the names more
uniform across packages.
./src/H5M.c
./src/H5Mprivate.h
./src/H5Mpublic.h
Nulled all the create functions. Most of the other callbacks
are to public functions. Removed H5Mcreate().
Changed hobjtype_t to group_t since it has to be the same
thing anyway.
./src/H5O.c
./src/H5Oprivate.h
./src/H5Osdim.c
./src/H5Osdtyp.c
Changed H5O_SIM_DIM to H5O_SDSPACE (simple data space) since
`simple data space' is its official name, not `simple
dimensions'. Will eventually add H5O_CDSPACE for comples data
spaces. Changed _sim_dim_ to _dspace_.
Replaced H5O_SIM_DTYPE and the compound data type messages
with a single H5O_DTYPE message. Changed _sim_dtype_ to _dtype_.
Changed H5O_STD_STORE to H5O_CSTORE (contiguous storage) since
contiguous storage is not necessarily standard. Changed
_std_store_ to _cstore_ in H5Ocstore.c
Added the H5O_EFL (external file list) message.
Changed H5O_new() to H5O_create() to make names more uniform
across packages.
./src/H5Oefl.c NEW
External file list message for specifying which non-hdf5 files
contain raw data for a dataset.
./src/H5P.c
./src/H5Pprivate.h
./src/H5Ppublic.h
Renamed and moved data structures to make the names conform to
our naming scheme.
./src/H5T.c
./src/H5Tprivate.h
./src/H5Tpublic.h
./src/H5Tpkg.h NEW
Data structures redesigned to be more flexible. The interface
was redesigned to make it more regular and to make some names
more uniform across packages.
./src/H5detect.c
Output was changed to produce a file that conforms to the hdf5
coding standard.
./src/Makefile.in
Generates H5Tinit.c by running H5detect.
./src/debug.c
Moved command argument processing.

* foo is a group that contains an entry for baz, but baz is not
|
|
|
|
|
|
* a group, then the results will be that REST points to `baz',
|
|
|
|
|
|
* GRP_ENT has an undefined object header address, and GRP_ENT
|
|
|
|
|
|
* is the symbol table entry for `bar' in `/foo'.
|

|
|
|
|
*
|
|
|
|
|
|
* If a file contains more than one object, then `/' is the name
|
|
|
|
|
|
* of the root object which is a group. Otherwise, a file can
|
|
|
|
|
|
* consist of a single object, not necessarily a group, whose
|
|
|
|
|
|
* name is `/foo' where `foo' is the value of the name messsage
|
|
|
|
|
|
* in the object header. A file can also contain no objects in
|
|
|
|
|
|
* which case the function returns so REST points to the
|
|
|
|
|
|
* beginning of NAME and OBJ_ENT and GRP_ENT contain undefined
|
|
|
|
|
|
* header addresses.

|
*
|
|
|
|
|
|
* Components of a name are separated from one another by one or
|
|
|
|
|
|
* more slashes (/). Slashes at the end of a name are ignored.
|
|
|
|
|
|
* If the name begins with a slash then the search begins at the
|
|
|
|
|
|
* root object, otherwise it begins at the group CWG, otherwise
|
|
|
|
|
|
* it begins at the current working group of file F. The
|
|
|
|
|
|
* component `.' is a no-op, but `..' is not understood by this
|
|
|
|
|
|
* function (unless it appears as an entry in the symbol table).

[svn-r139] ./src/*.[ch]
Removed the interface initialization argument from
FUNC_ENTER() and made it a locally-defined preprocessor
symbol, INTERFACE_INIT.
Changed `offset' to `address' and `length' to `size' in
documentation so it's more consistent. `Offset' still appears
occassionally when it refers to a byte offset within some
other data structure.
Moved interface termination function prototypes from public
header files to .c files and made them static.
./src/H5.c
./src/H5public.h
Added H5init() because it's possible that the predefined data
types are not initialized. This happens only if the first
call to the hdf5 library passes a predefined data type symbol
as an argument. There should be some way to fix this...
./src/H5A.c
./src/H5Aprivate.h
./src/H5Apublic.h
The free_func returns SUCCEED or FAIL, although the return
value is ignored by H5A. This is so we can use the various
H5*_close() functions to free things.
H5Ainc_ref() and H5Adec_ref() are no longer public. Many of
the other atom functions should also be made private, but I'll
save that for later...
Added additional template groups called H5_TEMPLATE_0 through
H5_TEMPLATE_7 that are used by the various template
subclasses.
Increased the number of bits used for atom groups to prevent
negative atoms.
./src/H5AC.c
./src/H5ACprivate.h
Changed H5AC_new() to H5AC_create() to make names more consistent.
./src/H5B.c
./src/H5Bprivate.h
Changed H5B_new() to H5B_create() to make names more consistent.
./src/H5C.c
./src/H5Cprivate.h
./src/H5Cpublic.h
Now supports multiple subclasses of templates, although it's
done with big switch statements. The default values for
templates are defined in the source file to which that
template belongs. This got rid of lots of needless
preprocessor constants.
Added H5Ccreate() to create a new template. Changed
H5C_release() to H5Cclose() to make the naming more
consistent.
./src/H5D.c
./src/H5Dprivate.h
./src/H5Dpublic.h
Enhanced to use the new dataset interface, and uses the enhanced
data type and data space interfaces, which haven't been
completely implemented. The dataset interface doesn't handle
non-contiguous storage, compression, or data type and space
conversions yet.
./src/H5F.c
./src/H5Fprivate.h
./src/H5Fpublic.h
Removed H5Fflush() since just calls H5F_flush(), which doesn't
do what the user would probably think it does, namely, flush
everything. It only flushes those things sitting in the H5AC
cache and the boot block.
Changed the `file_create_parms' field of H5F_low_t to just
`create_parms' since the `file' part is obvious.
./src/H5Fistore.c
Added some support for external files. Mostly just in the
file format and not supported much by the library yet. I need
to finish some dataset functions first.
Changed H5F_istore_new() to H5F_istore_create() to make names
more uniform across packages.
./src/H5Flow.c
Flushing a file causes the file to be physically extended to
the logical eof. This prevents H5F_open() from thinking a
file has been truncated. Most of the time the file will
already be that large, and when it isn't Unix will often just
allocate the final block anyway.
./src/H5G.c
./src/H5Gent.c
./src/H5Gnode.c
./src/H5Gpkg.h
./src/H5Gprivate.h
./src/H5Gstab.c
Removed H5G_basename()
Removed (temporarily) data type information from symbol table
entries and renamed H5G_CACHED_SDATA to H5G_CACHED_SDSPACE to
reflect that it's a simple data space and has nothing to do
with raw data.
Changed H5G_node_new() to H5G_node_create() and H5G_stab_new()
to H5G_stab_create() to make names more uniform across
packages.
Fixed an undefined address bug that happens when H5G_node_debug()
program doesn't pass enough info to H5G_node_load().
./src/H5H.c
./src/H5Hprivate.h
Changed H5H_new() to H5H_create() to make the names more
uniform across packages.
./src/H5M.c
./src/H5Mprivate.h
./src/H5Mpublic.h
Nulled all the create functions. Most of the other callbacks
are to public functions. Removed H5Mcreate().
Changed hobjtype_t to group_t since it has to be the same
thing anyway.
./src/H5O.c
./src/H5Oprivate.h
./src/H5Osdim.c
./src/H5Osdtyp.c
Changed H5O_SIM_DIM to H5O_SDSPACE (simple data space) since
`simple data space' is its official name, not `simple
dimensions'. Will eventually add H5O_CDSPACE for comples data
spaces. Changed _sim_dim_ to _dspace_.
Replaced H5O_SIM_DTYPE and the compound data type messages
with a single H5O_DTYPE message. Changed _sim_dtype_ to _dtype_.
Changed H5O_STD_STORE to H5O_CSTORE (contiguous storage) since
contiguous storage is not necessarily standard. Changed
_std_store_ to _cstore_ in H5Ocstore.c
Added the H5O_EFL (external file list) message.
Changed H5O_new() to H5O_create() to make names more uniform
across packages.
./src/H5Oefl.c NEW
External file list message for specifying which non-hdf5 files
contain raw data for a dataset.
./src/H5P.c
./src/H5Pprivate.h
./src/H5Ppublic.h
Renamed and moved data structures to make the names conform to
our naming scheme.
./src/H5T.c
./src/H5Tprivate.h
./src/H5Tpublic.h
./src/H5Tpkg.h NEW
Data structures redesigned to be more flexible. The interface
was redesigned to make it more regular and to make some names
more uniform across packages.
./src/H5detect.c
Output was changed to produce a file that conforms to the hdf5
coding standard.
./src/Makefile.in
Generates H5Tinit.c by running H5detect.
./src/debug.c
Moved command argument processing.

[svn-r139] ./src/*.[ch]
Removed the interface initialization argument from
FUNC_ENTER() and made it a locally-defined preprocessor
symbol, INTERFACE_INIT.
Changed `offset' to `address' and `length' to `size' in
documentation so it's more consistent. `Offset' still appears
occassionally when it refers to a byte offset within some
other data structure.
Moved interface termination function prototypes from public
header files to .c files and made them static.
./src/H5.c
./src/H5public.h
Added H5init() because it's possible that the predefined data
types are not initialized. This happens only if the first
call to the hdf5 library passes a predefined data type symbol
as an argument. There should be some way to fix this...
./src/H5A.c
./src/H5Aprivate.h
./src/H5Apublic.h
The free_func returns SUCCEED or FAIL, although the return
value is ignored by H5A. This is so we can use the various
H5*_close() functions to free things.
H5Ainc_ref() and H5Adec_ref() are no longer public. Many of
the other atom functions should also be made private, but I'll
save that for later...
Added additional template groups called H5_TEMPLATE_0 through
H5_TEMPLATE_7 that are used by the various template
subclasses.
Increased the number of bits used for atom groups to prevent
negative atoms.
./src/H5AC.c
./src/H5ACprivate.h
Changed H5AC_new() to H5AC_create() to make names more consistent.
./src/H5B.c
./src/H5Bprivate.h
Changed H5B_new() to H5B_create() to make names more consistent.
./src/H5C.c
./src/H5Cprivate.h
./src/H5Cpublic.h
Now supports multiple subclasses of templates, although it's
done with big switch statements. The default values for
templates are defined in the source file to which that
template belongs. This got rid of lots of needless
preprocessor constants.
Added H5Ccreate() to create a new template. Changed
H5C_release() to H5Cclose() to make the naming more
consistent.
./src/H5D.c
./src/H5Dprivate.h
./src/H5Dpublic.h
Enhanced to use the new dataset interface, and uses the enhanced
data type and data space interfaces, which haven't been
completely implemented. The dataset interface doesn't handle
non-contiguous storage, compression, or data type and space
conversions yet.
./src/H5F.c
./src/H5Fprivate.h
./src/H5Fpublic.h
Removed H5Fflush() since just calls H5F_flush(), which doesn't
do what the user would probably think it does, namely, flush
everything. It only flushes those things sitting in the H5AC
cache and the boot block.
Changed the `file_create_parms' field of H5F_low_t to just
`create_parms' since the `file' part is obvious.
./src/H5Fistore.c
Added some support for external files. Mostly just in the
file format and not supported much by the library yet. I need
to finish some dataset functions first.
Changed H5F_istore_new() to H5F_istore_create() to make names
more uniform across packages.
./src/H5Flow.c
Flushing a file causes the file to be physically extended to
the logical eof. This prevents H5F_open() from thinking a
file has been truncated. Most of the time the file will
already be that large, and when it isn't Unix will often just
allocate the final block anyway.
./src/H5G.c
./src/H5Gent.c
./src/H5Gnode.c
./src/H5Gpkg.h
./src/H5Gprivate.h
./src/H5Gstab.c
Removed H5G_basename()
Removed (temporarily) data type information from symbol table
entries and renamed H5G_CACHED_SDATA to H5G_CACHED_SDSPACE to
reflect that it's a simple data space and has nothing to do
with raw data.
Changed H5G_node_new() to H5G_node_create() and H5G_stab_new()
to H5G_stab_create() to make names more uniform across
packages.
Fixed an undefined address bug that happens when H5G_node_debug()
program doesn't pass enough info to H5G_node_load().
./src/H5H.c
./src/H5Hprivate.h
Changed H5H_new() to H5H_create() to make the names more
uniform across packages.
./src/H5M.c
./src/H5Mprivate.h
./src/H5Mpublic.h
Nulled all the create functions. Most of the other callbacks
are to public functions. Removed H5Mcreate().
Changed hobjtype_t to group_t since it has to be the same
thing anyway.
./src/H5O.c
./src/H5Oprivate.h
./src/H5Osdim.c
./src/H5Osdtyp.c
Changed H5O_SIM_DIM to H5O_SDSPACE (simple data space) since
`simple data space' is its official name, not `simple
dimensions'. Will eventually add H5O_CDSPACE for comples data
spaces. Changed _sim_dim_ to _dspace_.
Replaced H5O_SIM_DTYPE and the compound data type messages
with a single H5O_DTYPE message. Changed _sim_dtype_ to _dtype_.
Changed H5O_STD_STORE to H5O_CSTORE (contiguous storage) since
contiguous storage is not necessarily standard. Changed
_std_store_ to _cstore_ in H5Ocstore.c
Added the H5O_EFL (external file list) message.
Changed H5O_new() to H5O_create() to make names more uniform
across packages.
./src/H5Oefl.c NEW
External file list message for specifying which non-hdf5 files
contain raw data for a dataset.
./src/H5P.c
./src/H5Pprivate.h
./src/H5Ppublic.h
Renamed and moved data structures to make the names conform to
our naming scheme.
./src/H5T.c
./src/H5Tprivate.h
./src/H5Tpublic.h
./src/H5Tpkg.h NEW
Data structures redesigned to be more flexible. The interface
was redesigned to make it more regular and to make some names
more uniform across packages.
./src/H5detect.c
Output was changed to produce a file that conforms to the hdf5
coding standard.
./src/Makefile.in
Generates H5Tinit.c by running H5detect.
./src/debug.c
Moved command argument processing.

Removed H5G_basename()
Removed (temporarily) data type information from symbol table
entries and renamed H5G_CACHED_SDATA to H5G_CACHED_SDSPACE to
reflect that it's a simple data space and has nothing to do
with raw data.
Changed H5G_node_new() to H5G_node_create() and H5G_stab_new()
to H5G_stab_create() to make names more uniform across
packages.
Fixed an undefined address bug that happens when H5G_node_debug()
program doesn't pass enough info to H5G_node_load().

Changed H5H_new() to H5H_create() to make the names more
uniform across packages.
./src/H5M.c
./src/H5Mprivate.h
./src/H5Mpublic.h
Nulled all the create functions. Most of the other callbacks
are to public functions. Removed H5Mcreate().
Changed hobjtype_t to group_t since it has to be the same
thing anyway.
./src/H5O.c
./src/H5Oprivate.h
./src/H5Osdim.c
./src/H5Osdtyp.c
Changed H5O_SIM_DIM to H5O_SDSPACE (simple data space) since
`simple data space' is its official name, not `simple
dimensions'. Will eventually add H5O_CDSPACE for comples data
spaces. Changed _sim_dim_ to _dspace_.
Replaced H5O_SIM_DTYPE and the compound data type messages
with a single H5O_DTYPE message. Changed _sim_dtype_ to _dtype_.
Changed H5O_STD_STORE to H5O_CSTORE (contiguous storage) since
contiguous storage is not necessarily standard. Changed
_std_store_ to _cstore_ in H5Ocstore.c
Added the H5O_EFL (external file list) message.
Changed H5O_new() to H5O_create() to make names more uniform
across packages.
./src/H5Oefl.c NEW
External file list message for specifying which non-hdf5 files

[svn-r139] ./src/*.[ch]
Removed the interface initialization argument from
FUNC_ENTER() and made it a locally-defined preprocessor
symbol, INTERFACE_INIT.
Changed `offset' to `address' and `length' to `size' in
documentation so it's more consistent. `Offset' still appears
occassionally when it refers to a byte offset within some
other data structure.
Moved interface termination function prototypes from public
header files to .c files and made them static.
./src/H5.c
./src/H5public.h
Added H5init() because it's possible that the predefined data
types are not initialized. This happens only if the first
call to the hdf5 library passes a predefined data type symbol
as an argument. There should be some way to fix this...
./src/H5A.c
./src/H5Aprivate.h
./src/H5Apublic.h
The free_func returns SUCCEED or FAIL, although the return
value is ignored by H5A. This is so we can use the various
H5*_close() functions to free things.
H5Ainc_ref() and H5Adec_ref() are no longer public. Many of
the other atom functions should also be made private, but I'll
save that for later...
Added additional template groups called H5_TEMPLATE_0 through
H5_TEMPLATE_7 that are used by the various template
subclasses.
Increased the number of bits used for atom groups to prevent
negative atoms.
./src/H5AC.c
./src/H5ACprivate.h
Changed H5AC_new() to H5AC_create() to make names more consistent.
./src/H5B.c
./src/H5Bprivate.h
Changed H5B_new() to H5B_create() to make names more consistent.
./src/H5C.c
./src/H5Cprivate.h
./src/H5Cpublic.h
Now supports multiple subclasses of templates, although it's
done with big switch statements. The default values for
templates are defined in the source file to which that
template belongs. This got rid of lots of needless
preprocessor constants.
Added H5Ccreate() to create a new template. Changed
H5C_release() to H5Cclose() to make the naming more
consistent.
./src/H5D.c
./src/H5Dprivate.h
./src/H5Dpublic.h
Enhanced to use the new dataset interface, and uses the enhanced
data type and data space interfaces, which haven't been
completely implemented. The dataset interface doesn't handle
non-contiguous storage, compression, or data type and space
conversions yet.
./src/H5F.c
./src/H5Fprivate.h
./src/H5Fpublic.h
Removed H5Fflush() since just calls H5F_flush(), which doesn't
do what the user would probably think it does, namely, flush
everything. It only flushes those things sitting in the H5AC
cache and the boot block.
Changed the `file_create_parms' field of H5F_low_t to just
`create_parms' since the `file' part is obvious.
./src/H5Fistore.c
Added some support for external files. Mostly just in the
file format and not supported much by the library yet. I need
to finish some dataset functions first.
Changed H5F_istore_new() to H5F_istore_create() to make names
more uniform across packages.
./src/H5Flow.c
Flushing a file causes the file to be physically extended to
the logical eof. This prevents H5F_open() from thinking a
file has been truncated. Most of the time the file will
already be that large, and when it isn't Unix will often just
allocate the final block anyway.
./src/H5G.c
./src/H5Gent.c
./src/H5Gnode.c
./src/H5Gpkg.h
./src/H5Gprivate.h
./src/H5Gstab.c

thing anyway.
./src/H5O.c

./src/H5Osdim.c
./src/H5Osdtyp.c

`simple data space' is its official name, not `simple

spaces. Changed _sim_dim_ to _dspace_.

./src/H5Oefl.c NEW

symbol, INTERFACE_INIT.
Changed `offset' to `address' and `length' to `size' in
documentation so it's more consistent. `Offset' still appears
occassionally when it refers to a byte offset within some
other data structure.
Moved interface termination function prototypes from public
header files to .c files and made them static.
./src/H5.c
./src/H5public.h
Added H5init() because it's possible that the predefined data
types are not initialized. This happens only if the first
call to the hdf5 library passes a predefined data type symbol
as an argument. There should be some way to fix this...
./src/H5A.c
./src/H5Aprivate.h
./src/H5Apublic.h
The free_func returns SUCCEED or FAIL, although the return
value is ignored by H5A. This is so we can use the various
H5*_close() functions to free things.
H5Ainc_ref() and H5Adec_ref() are no longer public. Many of
the other atom functions should also be made private, but I'll
save that for later...
Added additional template groups called H5_TEMPLATE_0 through
H5_TEMPLATE_7 that are used by the various template
subclasses.
Increased the number of bits used for atom groups to prevent
negative atoms.
./src/H5AC.c
./src/H5ACprivate.h
Changed H5AC_new() to H5AC_create() to make names more consistent.
./src/H5B.c
./src/H5Bprivate.h
Changed H5B_new() to H5B_create() to make names more consistent.
./src/H5C.c
./src/H5Cprivate.h
./src/H5Cpublic.h
Now supports multiple subclasses of templates, although it's
done with big switch statements. The default values for
templates are defined in the source file to which that
template belongs. This got rid of lots of needless
preprocessor constants.
Added H5Ccreate() to create a new template. Changed
H5C_release() to H5Cclose() to make the naming more
consistent.
./src/H5D.c
./src/H5Dprivate.h
./src/H5Dpublic.h
Enhanced to use the new dataset interface, and uses the enhanced
data type and data space interfaces, which haven't been
completely implemented. The dataset interface doesn't handle
non-contiguous storage, compression, or data type and space
conversions yet.
./src/H5F.c
./src/H5Fprivate.h
./src/H5Fpublic.h
Removed H5Fflush() since just calls H5F_flush(), which doesn't
do what the user would probably think it does, namely, flush
everything. It only flushes those things sitting in the H5AC
cache and the boot block.
Changed the `file_create_parms' field of H5F_low_t to just
`create_parms' since the `file' part is obvious.
./src/H5Fistore.c
Added some support for external files. Mostly just in the
file format and not supported much by the library yet. I need
to finish some dataset functions first.
Changed H5F_istore_new() to H5F_istore_create() to make names
more uniform across packages.
./src/H5Flow.c
Flushing a file causes the file to be physically extended to
the logical eof. This prevents H5F_open() from thinking a
file has been truncated. Most of the time the file will
already be that large, and when it isn't Unix will often just
allocate the final block anyway.
./src/H5G.c
./src/H5Gent.c
./src/H5Gnode.c
./src/H5Gpkg.h
./src/H5Gprivate.h
./src/H5Gstab.c
Removed H5G_basename()
Removed (temporarily) data type information from symbol table
entries and renamed H5G_CACHED_SDATA to H5G_CACHED_SDSPACE to
reflect that it's a simple data space and has nothing to do
with raw data.
Changed H5G_node_new() to H5G_node_create() and H5G_stab_new()
to H5G_stab_create() to make names more uniform across
packages.
Fixed an undefined address bug that happens when H5G_node_debug()
program doesn't pass enough info to H5G_node_load().
./src/H5H.c
./src/H5Hprivate.h
Changed H5H_new() to H5H_create() to make the names more
uniform across packages.
./src/H5M.c
./src/H5Mprivate.h
./src/H5Mpublic.h
Nulled all the create functions. Most of the other callbacks
are to public functions. Removed H5Mcreate().
Changed hobjtype_t to group_t since it has to be the same
thing anyway.
./src/H5O.c
./src/H5Oprivate.h
./src/H5Osdim.c
./src/H5Osdtyp.c
Changed H5O_SIM_DIM to H5O_SDSPACE (simple data space) since
`simple data space' is its official name, not `simple
dimensions'. Will eventually add H5O_CDSPACE for comples data
spaces. Changed _sim_dim_ to _dspace_.
Replaced H5O_SIM_DTYPE and the compound data type messages
with a single H5O_DTYPE message. Changed _sim_dtype_ to _dtype_.
Changed H5O_STD_STORE to H5O_CSTORE (contiguous storage) since
contiguous storage is not necessarily standard. Changed
_std_store_ to _cstore_ in H5Ocstore.c
Added the H5O_EFL (external file list) message.
Changed H5O_new() to H5O_create() to make names more uniform
across packages.
./src/H5Oefl.c NEW
External file list message for specifying which non-hdf5 files
contain raw data for a dataset.
./src/H5P.c
./src/H5Pprivate.h
./src/H5Ppublic.h
Renamed and moved data structures to make the names conform to
our naming scheme.
./src/H5T.c
./src/H5Tprivate.h
./src/H5Tpublic.h
./src/H5Tpkg.h NEW
Data structures redesigned to be more flexible. The interface
was redesigned to make it more regular and to make some names
more uniform across packages.
./src/H5detect.c
Output was changed to produce a file that conforms to the hdf5
coding standard.
./src/Makefile.in
Generates H5Tinit.c by running H5detect.
./src/debug.c
Moved command argument processing.
