* [svn-r10238] Purpose:Quincey Koziol2005-03-201-95/+145
| | | | | | | | | | | | | | | | 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-r10081] Purpose: Some Kind of VerificationRaymond Lu2005-02-241-3/+50
| | | | | | | | | | | | | | | | | | Description: The library didn't handle incorrect hardware conversion for datatype. It simply did convert to incorrect data if any hardware didn't handle correctly. Solution: During configuration, incorrect hardware conversion is detected and some macros are defined. Use these macros to decide whether to register hardware conversion in H5T.c. If no hardware conversion function is registered for certain pair of datatypes, software conversion function will be used as the conversion path. Although slower than hardware conversion, we're more confident software conversion is accurate. So in one sentence to describe library's behavior, if some hardware conversion doesn't work well, software conversion will be used instead. Platforms tested: h5committest and fuss. Misc. update: some changes to configure's comments.
* [svn-r9984] Purpose: New feature and testRaymond Lu2005-02-101-0/+23
| | | | | | | | | | 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
* [svn-r9966] Purpose: Bug fixRaymond Lu2005-02-091-1/+1
| | | | | | | | | | | | | Description: H5Tget_member_value didn't return correct value if called after H5Tenum_valueof. It's because there's a sorting on the members of enum type in H5Tenum_valueof which changed the order of members. Solution: Made a copy of original type and do sorting on it to protect the original order. Platforms tested: fuss; tested v1.6 with h5committest Misc. update: RELEASE.txt
* [svn-r9959] Purpose: Bug fixRaymond Lu2005-02-081-4/+18
| | | | | | | | | | | | Description: For variable-length string, H5Tget_class returned H5T_STRING as its class. But H5Tdetect_class and H5Tget_member_class considered it as H5T_VLEN. This is fixed to let all these 3 functions treat it as H5T_STRING. Some test cases have been added to dtypes.c Platforms tested: heping - already tested for v1.6 with h5committest Misc. update: RELEASE.txt

* [svn-r9840] Purpose: Bug fix and new testRaymond Lu2005-01-201-3/+3
| | | | | | | | | | | | | Description: The functions for user-define floating-point type, like H5Tset_fields, H5Tset_offset, H5Tset_precision, H5Tset_size, have some minor bugs. For error checking, the library didn't include offset value somehow. Solution: Corrected those bugs. Platforms tested: h5committest and fuss 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

* [svn-r9342] Purpose:Quincey Koziol2004-09-301-2/+2
| | | | | | | | | | | | | | | | Bug fix/code cleanup Description: Clean up raw data I/O code to bundle the I/O parameters (dataset, DXPL ID, etc) into a single struct to pass around through the dataset I/O routines, since they are always passed together, until very near the bottom of the I/O stack.

* [svn-r9329] James Laird2004-09-281-417/+508
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Platforms tested: Visual Studio 7, sleipnir, arabica, verbena Misc. update:
* [svn-r9183] Purpose: New featureRaymond Lu2004-09-011-7/+7
| | | | | | | | | | | | Description: Restore 6 old error API functions back to the library to be backward compatible with v1.6. They are H5Epush, H5Eprint, H5Ewalk, H5Eclear, H5Eset_auto, H5Eget_auto. These functions do not have error stack as parameter. Solution: Internally, these functions use default error stack. Platforms tested: h5committest and fuss. Misc. update: RELEASE.txt
* [svn-r9053] Purpose:Quincey Koziol2004-08-081-28/+40
| | | | | | | | | | | | | | | | | | | Bug fix Description: Correct possible core dump when a datatype conversion function is registered with the library after a compound datatype has been converted (having it's type conversion information cached by the library). The compound datatype must have been created by inserting the fields in non-increasing offset order to see the bug. Solution: Re-sort the fields in the compound datatypes before recalculating the cached information when performing the conversion on them. Platforms tested: FreeBSD 4.10 (sleipnir) h5committested
* [svn-r8981] Purpose:Quincey Koziol2004-08-021-5/+8

* [svn-r8921] Purpose: new featureRaymond Lu2004-07-211-2/+17
| | | | | | | | | | | | | | Description: This is the second step of checkin for encoding and decoding objects. H5Tencode and H5Tdecode have been committed in the previous step. H5Sencode and H5Sdecode are checked in this time. Solution: Given object ID, these functions encode and decode object information into and from binary buffer and return new object ID. They take advantage of the existing codes of object header message and encode in the same format. Platforms tested: fuss and h5committest. Misc. update: RELEASE.txt
* [svn-r8892] Purpose:Quincey Koziol2004-07-161-3/+6
| | | | | | | | | | | | | | Code cleanup Description: Clean up a bunch of warnings and bring new code better inline with current library coding practice. Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest Misc. update:
* [svn-r8879] Raymond Lu2004-07-141-0/+148
| | | | | | | | | | | | | | Purpose: New feature Description: New API H5Tencode and H5Tdecode. Given object ID, H5Tencode encodes object information into a binary form. H5Tdecode decode an object information in a binary form, reconstructs the object and return a new object ID. Solution: Use object header functions H5O_dtype_decode and H5O_dtype_encode to facilitate them. The encoded binary is exactly like object header information. This is the first step checkin. Will check in H5Sencode and H5Sdecode later. Platforms tested: h5committed and fuss. Misc. update: will update release.txt after 2nd step checkin.
* [svn-r8801] Purpose:Quincey Koziol2004-07-031-5/+48
| | | | | | | | | | | | | | | Code optimization Description: Set up datatype ID for dataset's datatype on disk. This allows us to avoid repeatedly copying the datatype when an ID is needed.

* [svn-r8731] Purpose:Quincey Koziol2004-06-231-8/+7
| | | | | | | | | | | | | | | 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 Koziol2004-05-121-19/+24
| | | | | | | | | | | | | | | | | 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. Platforms tested: IBM p690 (copper) too minor to require h5committest
* [svn-r7917] Purpose:Quincey Koziol2003-12-061-11/+11
| | | | | | | | | | | | | | | | | | | Code cleanup Description: Clean up compiler warnings, especially the 'FUNC' variable not used which comes out in production mode. Solution: Had to add a new FUNC_ENTER_NOAPI_NOINIT_NOFUNC macro for those non-API functions which don't need the 'FUNC' variable defined. (This will be _so_ much easier when C99 is standard on all our supposed platforms, since it has a __FUNC__ macro... ) Platforms tested: FreeBSD 4.9 (sleipnir) too minor for h5committest (although there were lots of files changed, the change was minor in each one)
* [svn-r7875] Purpose:Quincey Koziol2003-11-241-0/+178
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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...

| | | | | | | | | | | | | | | Bug fix Description: Remove the [duplicated] native C9x datatype initializatin code from H5T.c and let the automatically generated code in H5Tinit.c handle initializing them, if they are allowed by the compiler. Platforms tested: FreeBSD 4.9 (sleipnir) Linux 2.4 (verbena, eirene) probably should be h5committested, but it's late and I'm fairly certain this will fix the problem... :-/

| | | | | | | | | | | | | | | Refactor code Description: Use "template macro" technique to eliminate a huge amount of repeated code in type initialization code (almost 1000 lines, between this change and the changes to the H5Tconv.c file earlier). This centralizes the common parts of the code and makes the different parts of the code more obvious. Platforms tested: FreeBSD 4.9 (sleipnir) too minor to require h5committest
