* [svn-r4360] Purpose:Quincey Koziol2001-08-151-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | Code cleanup (sorta) Description: When the first versions of the HDF5 library were designed, I remembered vividly the difficulties of porting code from a 32-bit platform to a 16-bit platform and asked that people use intn & uintn instead of int & unsigned int, respectively. However, in hindsight, this was overkill and unnecessary since we weren't going to be porting the HDF5 library to 16-bit architectures. Currently, the extra uintn & intn typedefs are causing problems for users who'd like to include both the HDF5 and HDF4 header files in one source module (like Kent's h4toh5 library). (Merged from the same changes to development branch) Solution: Changed the uintn & intn's to unsigned and int's respectively. Platforms tested: FreeBSD 4.4 (hawkwind)

Thanks to Quincey, the comment no longer applied. ./src/H5T.c Relaxed the H5Tpack() a little so it would pack compound data structures that had non-transient atomic members. ./tools/h5ls.c Added a `-g' (or `--group') flag that causes information to be printed about the specified group instead of the group's contents. (sort of like Unix's `ls -d'). The `-g' can be used in combination with `-r' to print information about the group and its contents.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./INSTALL Added warnings and a disclaimer about GNU, DEC, Irix64, and NT compilers that generate incorrect machine code. ./configure.in ./src/H5private.h Detects and includes <sys/param.h> which is needed on FreeBSD before <sys/proc.h> even though we only really using anything from <sys/proc.h> on the DEC Alpha. ./config/irix64 Turned off warnings for duplicate definitions from the linker because -lnsl on irix has the same stuff in it as -lc. ./config/irix6.x Split up the CC and CFLAGS settings like with irix64 so that compilers besides `-n32' can be used. ./bin/snapshot The snapshots are tagged with names like hdf5-1_1_52 which is similar to the way the releases are tagged (cvs doesn't allow dots in tags). ./test/dtypes.c ./src/H5private.h ./src/H5Tconv.c Fixed some alignment violations on the DEC when using high optimization levels. The DEC incorrectly optimizes certain memcpy() and memmove() calls when the source argument is not word aligned if the call looks like it's copying an atomic data type. ./test/hyperslab Worked around code generation bugs in the Irix64 Mongoose 7.00 compiler by casting some `unsigned long' values to `unsigned' in an expression. ./src/H5Ocomp.c Fixed a place where %d was used to print a size_t.

It's a one line change. Changed the way the library is closed so we have more control over the order the interfaces are shut down. Instead of registering an atexit() function for every interface in some haphazard order we just register one: H5_term_library() which then calls the H5*_term_interface() functions in a well-defined order. If the library is closed and then reopened repeatedly by calling H5close() and H5open() in a loop we only add one copy of the library termination functions with atexit(). Termination is a two-step process in order to help detect programming errors that would cause an infinite loop caused by the termination of one interface waking up some other previously terminated interface. The first step terminates the interface and *marks it as unusable*. After all interfaces are terminated then we mark them all as usable again. The FUNC_ENTER() macro has been modified to return failure or to dump core (depending on whether NDEBUG is defined) if we try to call an interface while it's shutting down. ./src/H5.c The H5dont_atexit() function returns failure if it's called more than once or if it's called too late. However, the error stack is not automatically printed on failure because the library might not be initialized yet ./test/chunk.c ./test/flush1.c ./test/flush2.c ./test/iopipe.c ./test/overhead.c ./test/ragged.c Changed the extra cast for Win32 so we do floating point division again -- it was just confusion about precedence and associativity of casting and the C coercion rules. Removed extra carriage returns inserted by broken operating system. ./src/H5Ffamily.c Fixed an bug where H5F_fam_write() lowered the EOF marker for one of the family members causing H5F_fam_read() to read zeros. ./test/h5test.h [NEW] ./test/h5test.c [NEW] ./test/Makefile.in ./test/bittests.c ./test/cmpd_dset.c ./test/dsets.c ./test/dtypes.c ./test/extend.c ./test/external.c Support library for test files. This isn't done yet but Katie's contractions are ~10 minutes apart so I figured I better back this stuff up just in case I'm not here next week... Eventually all test files will understand HDF5_DRIVER to name the low level file driver and parameters so we can easily test various drivers. They will also understand HDF5_PREFIX to prepend to the beginning of file names which is necessary for testing ROMIO with various drivers. Also, the cleanup function will know how to use the file name prefix and will understand different file driver naming schemes like file families. I'm not sure they'll understand the `gsf:' type prefixes yet. Note, the external test is completely commented out because I'm in the middle of modifying it. It will still compile and run but it doesn't test anything at the moment.

If not defined then H5private.h defines them. Changed all `int8' etc. to `int8_t'. ./src/H5A.c ./src/H5D.c ./src/H5F.c ./src/H5G.c ./src/H5I.c ./src/H5P.c ./src/H5R.c ./src/H5RA.c ./src/H5S.c ./src/H5T.c ./src/H5TB.c ./src/H5Z.c Calling H5*_term_interface() resets interface_initialize_g to FALSE so a subsequent call to H5open() (implied or explicit) reinitializes global variables properly. ./src/H5private.h ./src/H5Oefl.c ./src/H5S.c Changed MAX_SIZET, MAX_SSIZET, MAX_HSIZET, and MAX_HSSIZET to SIZET_MAX, SSIZET_MAX, HSIZET_MAX, and HSSIZE_MAX to they match the Posix.1 constants in <limits.h>. ./src/H5T.c ./src/H5Tconv.c ./src/H5Tpkg.h ./src/H5Tprivate.h ./src/H5detect.c Added 36 more integer hardware conversion functions to the type conversion table for conversions to/from `long long' and `unsigned long long'. The `long long' names will be changed shortly to make them portable to Win32. Changed H5T_init() to H5T_native_open() and added an H5T_native_close() to open and close the predefined native data types. Increased the initial size of the type conversion table from 64 to 128 entries. Reordered the 90 new integer conversion functions so the names that are printed favor `int' over `short' or `long' when two of them are the same. ./test/dtypes.c Added hardware and software integer conversion tests for the 56 functions I added recently but not the additional 36 checked in this time. That will come next. Call H5close() after each test so type conversion statistics are easier to follow. Try this: $ HDF5_DEBUG=t ./dtypes Added more debugging output for when things go wrong. ./src/H5private.h Removed trailing carriage-returns inserted by broken operating system ;-)

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.

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.

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.

---------------------- ./html/Compression.html [NEW] ./html/Datasets.html ./html/H5.format.html ./html/H5.user.html Documented compression. A couple of the H5P functions aren't quite implemented yet but they're coming soon... ./src/H5Dprivate.h ./src/H5E.c ./src/H5Epublic.h ./src/H5Farray.c ./src/H5Fistore.c ./src/H5Fprivate.h ./src/H5MF.c ./src/H5MFprivate.h ./src/H5O.c ./src/H5Ocomp.c [NEW] ./src/H5Oprivate.h ./src/H5P.c ./src/H5Ppublic.h ./src/H5Sprivate.h ./src/H5Ssimp.c ./src/H5Z.c [NEW] ./src/H5Zprivate.h [NEW] ./src/H5Zpublic.h [NEW] ./src/Makefile.in ./src/hdf5.h ./test/dsets.c ./test/istore.c Compression is now mostly working. Don't try to open a compressed dataset though because the compression message won't be read. ./html/Datatypes.html ./html/H5.api.html ./src/H5.c ./src/H5private.h ./src/H5D.c ./src/H5T.c ./src/H5Tconv.c ./src/H5Tpkg.h ./src/H5Tprivate.h ./src/H5Tpublic.h Added timing support. When compiled with H5T_DEBUG defined the library will print conversion bandwidths when the library closes. The H5Tregister functions take a string as the first argument so the statistics output is meaningful. ./MANIFEST Added new files. ./configure.in ./src/H5config.h.in Check for getrusage(). Check for compress2() in libz.a and the zlib.h header file. Added `z' to the debug list. ./src/H5B.c ./src/H5Bprivate.h ./src/H5Gnode.c ./src/debug.c Cleaned up some indentation and added support to print istore B-trees. From the debugger, give the B-tree address and the dimensionality from the layout message of the object header. ./src/h5ls.c The oid is printed as w:x:y:z where w and x are the file ID and y and z are the OID within the file. You can give z or y*2^32+z as an argument to the debugger to print the object header for the object. ./src/H5AC.c Cleaned up statistics and made them match those reported by H5T and H5Z. ./src/H5MM.c ./src/H5MMprivate.h ./src/H5Fistore.c Finally got rid of a couple of long-standing const cast warnings.
