* [svn-r518] Changes since 19980720Robb Matzke1998-07-201-4/+20
| | | | | | | | | | | | | | | | | | | | ---------------------- ./doc/html/H5.format.html ./src/H5Oattr.c ./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.
* [svn-r515] Changes since 19980715Robb Matzke1998-07-201-3/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./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.

The `x' was removed from the name to remind us of that: H5MM_xmalloc() -> H5MM_malloc(), etc. H5MM_calloc() takes one argument like H5MM_malloc() instead of two like calloc() because we almost always called it with `1' for one of the arguments anyway. The only difference between the two functions is that H5MM_calloc() returns memory which is initialized to zero. ./src/H5Gent.c ./src/H5Gprivate.h Removed H5G_ent_calloc() since it wasn't used. ./src/H5Fistore.c Fixed a bug found by Albert. Thanks, Albert! This fix combined with the changes to memory allocation prevent the library from failing an assertion if the application uses an unreasonable size for chunks (like Alberts 10000x10000x4). ./src/H5MF.c ./src/H5MFprivate.h Changed H5MF_free() to H5MF_xfree() since calling it with an undefined address is allowed.

Fixed some data type memory leaks during error recovery. ./src/H5Dprivate.h Added H5D_typeof() similar to H5D_entof() that returns a pointer directly to the dataset's type. This is used by H5Tcopy() when invoked on a dataset (see below). ./src/H5Epublic.h Fixed typos in H5E_BEGIN_TRY and H5E_END_TRY macros. ./src/H5F.c Closing a file with objects still open reports the file name in the warning message. Removed unnecessary invalidation of shared data types. ./src/H5Gent.c ./src/H5Gpkg.h ./src/H5Gprivate.h Added `const' to some arguments. ./src/H5O.c ./src/H5Oprivate.h ./src/H5Oshared.c An object header message can now be a pointer to a message in some other object header. The pointer is to the first message of the appropriate type in the other object header and hard link counts are maintained automatically to prevent dangling pointers. The old global heap method of message sharing is also supported although nothing actually uses it. ./src/H5Oattr.c ./src/H5Ocomp.c ./src/H5Ocont.c ./src/H5Odtype.c ./src/H5Oefl.c ./src/H5Olayout.c ./src/H5Oname.c ./src/H5Osdspace.c ./src/H5Oshare.c ./src/H5Ostab.c Changed the data type for the shared message info struct to H5O_shared_t and added an extra initializer to the class methods struct for the set_share method. ./src/H5Odtype.c Added the ability to share data type messages by pointing to other object headers. ./src/H5T.c ./src/H5Tpkg.h ./src/H5Tprivate.h ./src/H5Tpublic.h Added named data types and changed the functionality of some API functions as follows: * The term `read-only' means that a type handle cannot be modified with functions like H5Tset_*() or H5Tinsert(). * The term `immutable' means the same as `read-only' with the added restriction that H5Tclose() cannot be called for the type. A transient type is made immutable by calling H5Tlock(). * Handles to named types are always read-only. * Handles to predefined types are immutable. * A transient type can be converted to a named type by calling H5Tcommit(). This function will fail if the type is already named or is immutable. * The API function H5Tcommitted() returns an indication of whether a data type has been commited (or is named). If H5Tcommitted() returns TRUE for a data type obtained by calling H5Dget_type() on a dataset, then the dataset is using a shared data type. * H5Topen() returns a handle to a named type. * H5Tcopy() always returns a handle to a modifiable transient type even when invoked on a named type. Also, when invoked on a dataset it returns a modifiable transient type which is a copy of the dataset's data type. * Using a named data type in the call to H5Dcreate() causes the dataset object header to point to the named data type, but using a transient type causes the type to be copied into the dataset's object header. * The data type returned from H5Dget_type() is a named data type or a read-only transient data type depending on whether the dataset points to a named data type. The old behavior, to return a modifiable transient type, is accomplished by overloading H5Tcopy() to operate on datasets (see above). * H5Tshare(), H5Tunshare(), and H5Tis_shared() have been removed from the API. The following features were *not* implemented because they need more discussion: * A named data type can be opened by applying H5Topen() to a dataset in which case the data type is the data type of the dataset (or the data type to which the dataset points if the dataset has a shared data type). * A named data type can have attributes like groups or datasets. * The members of a compound data type can point to named data types. ./src/h5ls.c Reports `Data type' for named data type objects in the file.

This isn't fully tested yet, so hsize_t and hssize_t are defined as size_t and ssize_t in H5public.h. Setting them to larger values will trip up gcc versions less than 2.8.1 on x86 platforms. Documented unused function formals with `__unused__' before the formal name. This also has the effect of supressing warning messages for gcc since it's defined to be `__attribute__((unused))' in the H5private.h file. ./src/debug.c ./src/h5ls.c If the file name contains a `%' then the file is opened as a file family with H5P_DEFAULT for the file member access property list. ./src/h5ls.c The group name is optional, defaulting to `/'. ./src/hdf5.h Added some missing public header files.

Turned on more warning switches to gcc. ./config/linux Prints a warning if the gcc version is less than 2.8.1 since that version has problems with register allocation for `long long'. ./html/Datatypes.html Documented sharing of data types between datasets. ./src/H5G.c ./src/H5Gpublic.h Implemented H5Gmove(), H5Glink() and H5Gunlink() for hard links.

---------------------- ./MANIFEST ./src/Makefile.in ./test/Makefile.in Added new files. ./config/linux ./src/H5HL.c ./src/H5HLprivate.h ./src/H5MF.c ./src/H5MFprivate.h Added `-DH5HL_DEBUG -DH5MF_DEBUG' to the debug list. ./html/H5.format.html Updated shared object message information. ./src/H5D.c Datasets can now share data types. ./src/H5F.c Updated a comment that referred to H5ACC_WRITE. ./src/H5HG.c ./src/H5HGprivate.h Moved a few things around. Made debugging better so you can now give a collection address to ./src/debug and it shows some useful stuff. ./src/H5O.c ./src/H5Ocont.c ./src/H5Odtype.c ./src/H5Oefl.c ./src/H5Olayout.c ./src/H5Oname.c ./src/H5Onull.c ./src/H5Oprivate.h ./src/H5Osdspace.c ./src/H5Oshared.c [NEW] ./src/H5Ostab.c Supports shared messages. ./src/H5T.c ./src/H5Tpkg.h ./src/H5Tprivate.h ./src/H5Tpublic.h The H5Tshare() function allows the user to give the library hints about how a data type will be used. ./test/shtype.c Tests the H5Tshare() function. ./test/gheap.c Tests the global heap. ./configure.in ./config/BlankForm [NEW] ./config/alpha-dec ./config/freebsd2.2.1 ./config/hpux10.20 ./config/irix6.2 ./config/irix64 ./config/linux ./config/powerpc-ibm-aix4.2.1.0 ./config/rs6000-ibm-aix4.1.4.0 ./config/solaris2.5 Cleaned up lots of configuration stuff and made the site configuration files lots easier and more uniform. To make a new file grab the BlankForm and modify it. By default, debugging is turned on for most packages. Within a package one can use `#ifdef H5AC_DEBUG' to wrap debugging code. Other options are: --enable-debug --enable-debug=yes The default, most but not all packages. --disable-debug --enable-debug=no --enable-debug=none The symbol NDEBUG is defined and none of the package debug symbols. --enable-debug=all Debugging is turned on for all packages. This might produce lots of output. --enable-debug=g,d Debugging is turned on for H5G and H5D. A compile mode is also now supported --enable-production --enable-production=yes The library is compiled with optimizations turned on. The compiler flags are augmented by adding PROD_CFLAGS and PROD_CPPFLAGS which are defined in the site config file. --disable-production --enable-production=no The default. The library is compiled for development by including DEBUG_CFLAGS and DEBUG_CPPFLAGS defined in the site config file. This is usually just `-g'. --enable-production=profile --enable-production=pg Builds a library for profiling by including the flags from PROFILE_CFLAGS and PROFILE_CPPFLAGS defined in the site config file. This is usullay just `-pg' but it could include optimization flags as well depending on the type of profile one wants. In summary, configure by saying `./configure' and you'll get a development version of the library. Configure by saying `./configure --enable-production --disable-debug' and you'll get a production version with no debugging code.
