* [svn-r5467] Purpose:Quincey Koziol2002-05-281-23/+31
| | | | | | | | | | | | | | | | | | | | | | | | Code cleanup. Description: Took Robb's recent ideas for improving the FUNC_ENTER/FUNC_LEAVE macros equivalents in the SAF library and adapted them to our library. I added an additional macro which is equivalent to FUNC_ENTER: FUNC_ENTER_NOINIT - Has the API tracing code, etc. from FUNC_ENTER but none of the library or interface initialization code. This is to be used _only_ for static functions and those which explicitly cannot have the library or interface initialization code enabled (like the API termination routines, etc.). This allowed many more of the functions in the library [but not all yet :-(] to be wrapped with FUNC_ENTER[_NOINIT]/FUNC_LEAVE pairs. It also reduced the size of the library and executables (by cutting out a bunch of code which was never executed), I'll e-mail the exact results when I've finished editing it. Platforms tested: IRIX64 6.5 (modi4)
* [svn-r4842] Purpose:Quincey Koziol2002-01-171-52/+44
| | | | | | | | | | | | Feature improvement Description: Re-write how the free-list headers were used, to reduce the amount of space added to each malloc request. Reduced header for array and block free list items from 24 bytes to 8 bytes and eliminated the header for fixed-size free list items entirely. This should reduce the amount of memory that the library uses. Platforms tested: FreeBSD 4.5 (sleipnir) & IRIX64 6.5 (modi4)
* [svn-r4586] Purpose:Quincey Koziol2001-11-021-1/+1
| | | | | | | | | | | | | | Code speedups, etc. Description: Bring in new algorithms and data structures for dealing with hyperslabs. This speeds up the hyperslab I/O for non-regular hyperslabs by a huge amount. Currently, the new API functions are ifdef'ed out, pending discussion and consensus approval. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4355] Purpose:Quincey Koziol2001-08-141-14/+14
| | | | | | | | | | | | | | | | | | | | | | 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). Solution: Changed the uintn & intn's to unsigned and int's respectively. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4038] Purpose:Quincey Koziol2001-06-211-25/+19
| | | | | | | | | | | | | Code clean/bug fix Description: H5FL (free-list manager) code currently is taking an hsize_t as the size of a memory block to allocate. On many machines, the size of an hsize_t is greater than the size of a size_t, potentially leading to incorrect memory allocations in rare circumstances. Solution: Changed hsize_t parameters and variables to size_t. Platforms tested: FreeBSD 4.3 (hawkwind)
* [svn-r3993] Purpose:Quincey Koziol2001-06-111-1/+2
| | | | | | | | | | | | | Bug fix for Pablo integration Description: Several API functions were using FUNC_ENTER, without using FUNC_LEAVE, HRETURN or HRETURN_ERROR to leave the function. (Using "plain" 'return' statements instead). Solution: Changed return statements to FUNC_LEAVE, HRETURN or HRETURN_ERROR, as appropriate. Platforms tested: FreeBSD 4.3 (hawkwind)
* [svn-r3781] Purpose:Bill Wendling2001-04-051-6/+6
| | | | | | | | | | | | | | | | | | Update Description: Changed #include <hdf_file.h> construct to #include "hdf_file.h" so that the GNU compiler can more easily pick up the dependencies which it places in the .depend and Dependencies files. Also regenerated the Dependencies to go along with this. Platforms tested: Linux
* [svn-r3252] Purpose:Quincey Koziol2001-01-091-15/+28
| | | | | | | | | | | | | Code cleanup. Description: Fixed _lots_ (I mean _tons_) of warnings spit out by the gcc with the extra warnings. Including a few show-stoppers for compression on IRIX machines. Solution: Changed lots of variables' types to more sensible and consistent types, more range-checking, more variable typecasts, etc. Platforms tested: FreeBSD 4.2 (hawkwind), IRIX64-64 (modi4)
* [svn-r3236] Purpose:Quincey Koziol2001-01-041-4/+4
| | | | | | | | Clean up code. Description: Cleaned up various compiler warnings. Platforms tested: FreeBSD 4.2 (hawkwind)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug fixes Description: All tests were core=dumping in IRIX64. The bug is in Generic property list creation in which malloc asked for 2*64-1 bytes due to coding bug. The object creation failed but the return code was not checked. Program eventually crashed. Solution: H5F.c: Check the return code from new file object creation and flag error accordingly. H5FL.c: H5FL_arr_free is a replacement for H5MM_xfree which accepts null value as a legal argument value. H5FL_arr_free assert on it. Since other parts of the code have been passing null value to H5MM_xfree, H5FL_arr_free must accept it too until all the calling routines are changed to not pass Null. H5P.c: some routine passes in 0 as the hashsize value which is uintn. The expression (hashsize-1) underflows to the largest unsigned int for some machines. Thus the calloc failed. Cast hashsize to unsigned int first (this assumes hashsize stays within the signed int data range. H5Smpio.c: Added the extra parameter because the H5FD_write has been redefined. Platforms tested: IRIX64 -64 and -n32

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ** src/H5Tconv.c ** src/H5Tpkg.h ** src/H5Tpublic.h The H5T_conv_struct_opt() function had a design flaw -- it didn't keep information about the stride to use to step through the temporary/background-value buffer and thus nested invocations would clobber each other's temp buffers. This was fixed by splitting the `stride' argument into `buf_stride' and `bkg_stride' arguments for all the conversion functions. THIS IS AN API CHANGE, but users will get a compiler warning when they pass their conversion function pointer to H5Tregister(). ** src/H5T.c ** src/H5Tprivate.h Added a bkg_stride argument to the H5T_convert() definition in order to fix a bug related to the optimized compound datatype conversion function. ** src/H5T.c ** src/H5A.c ** src/H5D.c ** src/H5Ofill.c ** src/H5P.c Added bkg_stride=0 argument to the H5T_convert() calls. ** test/dtypes.c Added a test for the H5T_conv_struct_opt() bug fixed above. ** src/H5FL.c The H5FL_term() function should return non-zero even when it couldn't free all the free lists do to their being used by some other package. When that other package terminates it will return non-zero, causing H5FL_term() to be called again. This fixes some of the `infinite loop closing library' messages. ** tools/pdb2hdf Uses print_version() instead of doing that itself. ** src/H5Ppublic.h Renamed H5Pget_gc_reference() declaration to make it match the definition. ** src/H5FDlog.c Added API tracing macros. Removed `const' qualifier from a `char*' member of a struct which was allocated on the heap. ** src/H5TB.c Added curly braces to a couple deeply-nested `if' statements to make them clearer and to shut up the increadibly stupid and just plain incorrect gcc warning about ambiguous `else'. ** test/titerate.c Removed incomplete initialization in favor of memset() for one auto variable to stop compiler warnings. ** tools/Depencencies Regenerated to remove references to h5dumputil.c
