* [svn-r10238] Purpose:Quincey Koziol2005-03-201-1/+1
| | | | | | | | | | | | | | | | Optimization Description: Speed up I/O on enumerated datatypes (including those nested in compound datatypes, arrays, etc.) if the destination datatype is a proper superset of the source datatype. Solution: Detect the situation and treat as no-op datatype conversion. Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
* [svn-r10087] Purpose: New feature and testRaymond Lu2005-02-251-3/+20
| | | | | | | | | | | Description: Somehow, the hardware conversions between "long double" and other native floating-point types were left out. Solution: Added the hardware conversion functions in H5Tconv.c and test cases in dtypes.c. Platforms tested: h5committest and fuss. Misc. update: updated MANIFEST to replace bin/reconfigure.sh with bin/reconfigure
* [svn-r9984] Purpose: New feature and testRaymond Lu2005-02-101-0/+103
| | | | | | | | | | Description: Added support of hardware conversion between "long double" and integers(mainly in H5Tconv.c) and some test cases(mainly in test/dtypes.c). Platforms tested: h5committest and fuss. Misc. update: RELEASE.txt

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug Fix/Code Cleanup/Doc Cleanup/Optimization/Branch Sync :-) Description: Generally speaking, this is the "signed->unsigned" change to selections. However, in the process of merging code back, things got stickier and stickier until I ended up doing a big "sync the two branches up" operation. So... I brought back all the "infrastructure" fixes from the development branch to the release branch (which I think were actually making some improvement in performance) as well as fixed several bugs which had been fixed in one branch, but not the other. I've also tagged the repository before making this checkin with the label "before_signed_unsigned_changes".

* [svn-r9445] Purpose: Bug fixRaymond Lu2004-10-211-4/+4
| | | | | | | | | | | Description: "char" was considered as always "signed char" in data type conversion. However, ISO C leaves the definition of "char" to individual implementation. i.e. for IBM AIX C compiler, it's treated as "unsigned char". Solution: Changed all "char" to "signed char". Don't even do "char" anymore because its definition is up to each vendor. Platforms tested: h5committest

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Purpose: Feature Description: Datatypes and groups now use H5FO "file object" code that was previously only used by datasets. These objects will hold a file open if the file is closed but they have not yet been closed. If these objects are unlinked then relinked, they will not be destroyed. If they are opened twice (even by two different names), both IDs will "see" changes made to the object using the other ID. When an object is opened using two different names (e.g., if a dataset was opened under one name, then mounted and opened under its new name), calling H5Iget_name() on a given hid_t will return the name used to open that hid_t, not the current name of the object (this is a feature, and a change from the previous behavior of datasets). Solution: Used H5FO code that was already in place for datasets. Broke H5D_t's, H5T_t's, and H5G_t's into a "shared" struct and a private struct. The shared structs (H5D_shared_t, etc.) hold the object's information and are used by all IDs that point to a given object in the file. The private structs are pointed to by the hid_t and contain the object's group entry information (including its name) and a pointer to the shared struct for that object. This changed the naming of structs throughout the library (e.g., datatype->size is now datatype->shared->size). I added an updated H5Tinit.c to windows.zip.

* [svn-r8731] Purpose:Quincey Koziol2004-06-231-1/+0
| | | | | | | | | | | | | | | Code cleanup & minor optimization Description: Re-work the way interface initialization routines are specified in the library to avoid the overhead of checking for them in routines where there is no interface initialization routine. This cleans up warnings with gcc 3.4, reduces the library binary size a bit (about 2-3%) and should speedup the library's execution slightly. Platforms tested: FreeBSD 4.10 (sleipnir) w/gcc34 h5committest
* [svn-r8683] Purpose:Quincey Koziol2004-06-141-193/+185
| | | | | | | | | | | | | Code optimization Description: Use 'size_t' instead of 'hsize_t' to track the number of elements in memory buffers, especially for type conversion. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8670] Purpose:Quincey Koziol2004-06-131-0/+2
| | | | | | | | | | | | | Code optimization Description: Avoid a memory copy by directly reading from the variable-length sequence buffer when there is no type conversion on the way to disk. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8507] Purpose:Quincey Koziol2004-05-121-0/+1
| | | | | | | | | | | | | | | | | Code optimization Description: Eliminate many redundant lookups to check for no-op type conversion by remembering that a type conversion path is the no-op path. Also, don't allow non-no-op conversions which happen to be no-ops on a particular machine (such as int<->long conversions on machines where int and long are the same size and format, etc.) to replace the default no-op conversion. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.9 (sleipnir) w/parallel
* [svn-r8427] Purpose:Quincey Koziol2004-04-281-0/+2
| | | | | | | | | | | | | | | | Bug fix (sorta) Description: Add hack to allow the MS Visual Studio 6 compiler to build the library. It cannot cast unsigned long long values to float or double values. So, add another configuration macro to disable this conversion in the library. Just the "hardware" conversion is disabled, so the library will still correctly convert unsigned long long to float and double values, it will just happen more slowly with the "software" conversion routine. Platforms tested: FreeBSD 4.9 (sleipnir) with "Windows" setting faked inappropriate for h5committest

| | | | | | | | | | | | | Optimization Description: Speed up various parts of the library by setting a global variable for the endianness of the machine at library startup and use that variable instead of repeatedly querying the endianness of the native int datatype.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Omnibus floating-point bug fix changes Description: There are a number of problems in the floating-point conversion code that were exposed by Ray's recent int<->float checkin: - The 'my_isnan' code in test/dtypes.c was broken and would always return true. The meant that the actual values in the float<->float conversion tests were _never_ checked, hiding the other bugs included in this checkin. - A recent change I made to the type conversion code used "FLT_MIN" instead of "-FLT_MAX" for the most negative 'float' value for the double->float conversion, which meant that any the negative number that was converted from a double to a float would have been mapped to zero, essentially. - A change that Robb appeared to have made ~2.5 years ago to the "generic" float->float conversion routine appears to be incorrect and I've backed it out. - Floating-point conversions on SGI's which converted denormalized values would be mapped to zero instead of being propertly preserved in the new type. This was addressed by an SGI-specific system call to prevent the behavior. Solution: Described above, generally. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest Misc. update: release_docs/RELEASE update forthcoming...
* [svn-r7868] Purpose: new featureRaymond Lu2003-11-211-0/+200
| | | | | | | | | | Description: data type conversion between integers and float numbers. (Cover your ears. It's going to explode.:) Solution: covers all native type conversion. Mainly uses hardware conversion but handles overflow more gracefully. Platforms tested: h5committest
* [svn-r7842] Purpose:Quincey Koziol2003-11-131-12/+7
| | | | | | | | | | | | | | | | | | | Bug fix Description: Variable length strings and sequences with NULL pointers were not handled by library, causing problems access the data. This also affected fill values for variable-length datatypes. Solution: Address the issues in the library by detecting NULL sequences/strings and avoid trying to convert them. Patched up dumper to display NULL sequences/strings. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest
* [svn-r7616] Purpose:Quincey Koziol2003-10-131-8/+8
| | | | | | | | | | | | | | | Code cleanup Description: Change field member count and indices for compound and enumerated types from 'int' to 'unsigned' to better reflect actual use.

* [svn-r7468] Purpose:Quincey Koziol2003-09-121-1/+5
| | | | | | | | | | | | | | | | | | Code cleanup, etc. Description: Generalize Ray's datatype fixes to handle packing compound datatypes which are the base type of an array or variable-length type, etc. Also track "packedness" of a compound datatype from it's creation, instead of only setting the 'packed' flag after the datatype was explicitly packed. Updated docs to reflect that a compound datatype is allowed to grow (but not shrink). Platforms tested: FreeBSD 4.9 (sleipnir) h5committest
* [svn-r7461] Purpose: bug #1017Raymond Lu2003-09-101-0/+1

* [svn-r7434] Purpose:Quincey Koziol2003-08-311-4/+7
| | | | | | | | | | | | | | | | | | | | Bug Fix and code cleanup Description: Correct error in H5T_detect_class that was causing nested compound datatypes with to not detect the datatype class of fields correctly, which caused errors with fill-values, variable-length datatypes and chunks later on. Return the rank of the array datatype from H5Tget_array_dims(), like H5Sget_dims(). Lots of cleanups to datatype code, to make the handling of arrays, compound types, variable-length strings and sequences and enumerated types more consistent and robust. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest

* [svn-r6837] Purpose:Quincey Koziol2003-05-081-4/+37
| | | | | | | | | | | | | | | Code cleanup. Description: Move many package or internal function prototypes and macro definitions into tighter scope according to their current use. Added more comments where appropriate. Eliminate ancient, unused functions. Added a couple "accessor" functions to get parts of data structures which were moved out of scope. Platforms tested: h5committested

* [svn-r6395] Purpose:Quincey Koziol2003-02-121-0/+23
| | | | | | | | | | | | | | | | | | | | | | | Code cleanup. Description: Break up the ~9350 line H5T.c module into smaller pieces, which contain code for a particular feature or support for a datatype class. This should make the "main" H5T code (still in H5T.c) easier to support, as well as removing some of the "minor" routines from the user applications which don't use them (my rough estimates show about 4% reduction (~30K on a FreeBSD machine) in optimized, staticly-linked binaries for very simple programs) Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir) Misc. update: Update MANIFEST
* [svn-r6387] Purpose:Quincey Koziol2003-02-101-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir) serial & parallel Misc. update: Updated release_docs/RELEASE

* [svn-r5931] MuQun Yang2002-09-201-162/+162
| | | | | | | | | | | | Purpose: __DLL__ is a keyword in some platforms and __DLL__ is also defined as a macro for windows DLL applications. That causes problems. Description: Solution: Use H5_DLL*** to replace __DLL***__ at all header files. Change the macro defination at H5api_adpt.h. Platforms tested: linux2.2.18smp, irix64, solaris 2.7 and windows 2000
* [svn-r5764] Raymond Lu2002-07-031-4/+4
| | | | | | | | | | | Purpose: Bug Fix. Description: VL type memory leak when data is overwritten. Solution: Free heap objects holding old data. Platforms tested: Linux 2.2(eirene), IRIX 6.5(paz).
* [svn-r5123] Raymond Lu2002-03-291-0/+3

* [svn-r4863] ./hdf5-devel/src/H5Tpkg.hRobb Matzke2002-01-251-0/+5
| | | | | | | | | | | | More optimizing for byte order conversion. Mostly just making code easier to follow by simplifying Duff's device coding of the loops. I also split the conversion function into two functions with different names so output from H5T debugging indicates whether the optimized or unoptimized case was invoked. 2002-01-25 10:48:34 Robb Matzke <matzke@arborea.spizella.com> *: Added prototype for H5T_conv_order_opt().
* [svn-r4696] Raymond Lu2001-12-111-1/+1
| | | | | | | | | | | | | | | | | Purpose: Modify H5Fclose behavior Description: The HDF5 actual file close behaves in several ways in terms of if there are still objects(dataset, group, datatype) opened in file. Solution: Added a new file access property, file close degree. It has four values, H5F_CLOSE_DEFAULT H5F_CLOSE_WEAK H5F_CLOSE_SEMI H5F_CLOSE_STRONG The way a file is closed is decided by these values. Platforms tested: IRIX64 6.5, SunOS 5.6, FreeBSD 4.4
* [svn-r4629] Purpose:Quincey Koziol2001-11-201-1/+0
| | | | | | | | Bug fix for code cleanup... :-) Description: Fix a few problems introduced in my previous code cleanup. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4355] Purpose:Quincey Koziol2001-08-141-6/+6
| | | | | | | | | | | | | | | | | | | | | | 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)
