* [svn-r13156] Description:Quincey Koziol2007-01-191-3/+4
| | | | | | | | | Begin refactoring code to straighten out the contorted code that handles shared messages. Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
* [svn-r13121] Description:Quincey Koziol2007-01-081-1/+0
| | | | | | | | | | Add support & tests for using shared datatypes with shared & un-shared attributes. Involves some fairly icky code to make the "copy on write" paradigm for shared attributes work. Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)

* [svn-r12902] Checkin of Shared Object Header Message work.James Laird2006-11-131-4/+2
| | | | | | | | | | | | This feature is still in progress; Shared Object Header Messages are not complete as a feature and are not thoroughly tested. There are still "TODO" comments in the code (comments with the word "JAMES" in them, so as not to be confused with other TODO comments). Hopefully this checkin will reduce the liklihood of conflicts as I finish implementing this feature. All current tests pass on juniper, copper (parallel), heping, kagiso, and mir.
* [svn-r12736] Description:Quincey Koziol2006-10-091-5/+4
| | | | | | | | | | | | | | | | | | | Add "use the latest format" support for dataspace object header encode/ decode routines and clean up format a bit for the latest format (new to 1.8.x releases) Remove storing 'perm' parameter for array datatypes in memory and the file, and add test to make certain that if any user applications are attempting to store them, we get some reports back. (Should be unlikely, since the RefMan says that the parameter is not implemented and is unsupported). Carry those changes into the tests, etc. Clean up a bunch more compiler warnings. Tested on: FreeBSD/32 4.11 (sleipnir) w/threadsafe Linux/32 2.4 (heping) w/FORTRAN & C++ Linux/64 2.4 (mir) w/enable-1.6-compat

* [svn-r12435] Purpose: Bug fixRaymond Lu2006-06-231-2/+11
| | | | | | | | | | | | Description: Mac OS 10.4 on PowerPC chip has some errors to convert (unsigned) long long to long double. When the bit sequences are 0x003ff..., 0x007fff..., 0x00ffff..., 0x01ffff..., 0x7fffff..., the converted values are twice as big as they should be. Solution: Detect the error in configure and disable the compiler conversion and test case. Platforms tested: h5committest, Mac OS 10.4, and fuss.
* [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.... :-)
* [svn-r11384] Purpose:Quincey Koziol2005-09-121-0/+1
| | | | | | | | | | | | | | | | | | | | | 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.... Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4 Mac OS X
* [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.

| | | | | | | | | | | Description: Data conversion function H5T_conv_i32le_f64le() was unused. Because we have new conversion functions for integers and floating numbers, this old function is taken out. Platforms tested: fuss - simple change. Misc. update:

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

* [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

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