* [svn-r12425] Purpose: Bug fixRaymond Lu2006-06-201-6/+7
| | | | | | | | | | | | | | | Description: Data conversion from long double to (unsigned) long long returns some incorrect values on Mac OS 10.4 and SGI IRIX64 6.5. The conversions start to go wrong when the long double is 20041683600089727.779961 (0x4351ccf385ebc8a0bfcc2a...). If adjusting the values higher by assigning 0x...c8a0cf... or 0x...c8a0df..., the converted values go wild. Solution: Detect this error in configure.in and disable compiler conversions from long double to (unsigned) long long for Mac OS 10.4 and IRIX64 6.5. Platforms tested: h5committest, Mac OS 10.4, and IRIX64 6.5.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New feature Description: Check in baseline for compact group revisions, which radically revises the source code for managing groups and object headers. WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! This initiates the "unstable" phase of the 1.7.x branch, leading up to the 1.8.0 release. Please test this code, but do _NOT_ keep files created with it - the format will change again before the release and you will not be able to read your old files!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! Solution: There's too many changes to really describe them all, but some of them include: - Stop abusing the H5G_entry_t structure and split it into two separate structures for non-symbol table node use within the library: H5O_loc_t for object locations in a file and H5G_name_t to store the path to an opened object. H5G_entry_t is now only used for storing symbol table entries on disk. - Retire H5G_namei() in favor of a more general mechanism for traversing group paths and issuing callbacks on objects located. This gets us out of the business of hacking H5G_namei() for new features, generally. - Revised H5O* routines to take a H5O_loc_t instead of H5G_entry_t - Lots more... Platforms tested: h5committested and maybe another dozen configurations.... :-)

| | | | | | | | | | | | | | | | | | | | | Code cleanup Description: Merge back changes from "compact group" work that improve the infrastructure of the library and may impact others. In this round of merging, that includes: - Move datatype allocation into single internal routine, instead of duplicated code that was spread out in a dozen or so places. - Clean up guts of object header routines (H5O_*) to allow for some of the fancieroperations that need to be performed on groups, along with some general improvements. - Added a new error code - Some minor cleanups in other code....

* [svn-r11332] Purpose: Minor Change to Macro NamesRaymond Lu2005-09-011-26/+26
| | | | | | | | | Description: Changed the names of macros defined in H5Tpkg.h from H5T_CONV_INTERIM_XXX_XXX to H5T_CONV_INTERNAL_XXX_XXX to be more descriptive. Platforms tested: fuss - simple change
* [svn-r11317] Purpose: Minor change to macro namesRaymond Lu2005-08-301-13/+13
| | | | | | | | | | | | Description: Changed the names of the interim macros for data conversion checked in yesterday from the SOURCE_DESTINATION style (like FP_FP or LDOUBLE_LLONG) to the H5T_CONV_INTERIM_SOURCE_DESTINATION style (like H5T_CONV_INTERIM_FP_FP OR H5T_CONV_INTERIM_LDOUBLE_LLONG), to be more descriptive. These macros are defined in H5Tpkg.h and used in H5Tconv.c and H5T.c for interim purpose. Platforms tested: fuss - simple change.
* [svn-r11311] Purpose: New features.Raymond Lu2005-08-291-0/+96
| | | | | | | | | | | | | | | | | | | | Description: Added 2 new configure options, --enable-exception and --enable-accuracy. --enable-exception lets the library check whether user's exception handling functions are present during compiler data conversions and use them if they are. When it's disabled, this step is skipped to improve conversion speed. This step isn't implemented yet for soft conversions because there would be little gain in speed. --enable-accuracy guarantees data accuracy during data conversions. It means the library will choose compiler conversions only if the accurate data is secured. Otherwise, the library will go for the library's own conversions. If this option is disabled, the library uses compiler conversions in favor of their speed as long as they work even if data can be incorrect. Platforms tested: h5committest and fuss. Some systems may fail after this checkin.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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".

| | | | | | | | | | | 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.

* [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.

* [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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
