* [svn-r11424] Purpose:Quincey Koziol2005-09-171-233/+255
| | | | | | | | | | | | | | | | | | | | | Code cleanup/bug fix Description: Hoist function call out of inner loop of type conversion by retrieving source & destination precisions once, outside the loop. There's still some overhead because this information is stored in variables set at run-time, when it's really constant for the particular machine. Further work to set compiler macros would allow this code to be optimized better by the compiler with dead code removal. We'll continue to work on this area... Also, made new internal H5T_compiler_conv routine static instead of of private, until we need to reference it from another source code module. Platforms tested: h5committest FreeBSD 4.11 (sleipnir)
* [svn-r11415] Purpose: Internal design change.Raymond Lu2005-09-141-3/+3
| | | | | | | | | | | | | | | | | Description: H5T_register() replaces any existing data conversion path with a new path. Solution: Added a parameter to H5T_register() and H5T_path_find() to signal the library whether the new conversion path is from API function H5Tregister() or from private function like H5T_init_interface(). If it is from H5Tregister(), replace existing path. If it's from H5T_init_interface() and the library is trying to register default hard conversion functions, don't replace existing path because the path is registered by the library. For example, the library registered H5T_conv_int_float() and is trying to register H5T_conv_long_float(). The size of long is equal to int. There's no need to replace the path H5T_conv_int_float(). Platforms tested: h5committest and fuss.
* [svn-r11395] Purpose: Bug fixRaymond Lu2005-09-121-238/+235
| | | | | | | | | | | | | | | | | | Description: Quincey added the condition branch (else if (*((ST*)S) != (ST)((DT)(*((ST*)S))))) in the definition of the macro H5T_CONV_Fx_CORE. It handles a special situation when the source is "float" and assigned the value of "INT_MAX". Compilers do roundup making this value "INT_MAX+1". This branch is to check that situation and return exception for some compilers, mainly GCC. The branch if (*((ST*)S) > (DT)(D_MAX) || (S_PREC < D_PREC && *((ST*)S) == (DT)(D_MAX))) is for some compilers like Sun, HP, IBM, and SGI where under the same situation the "int" doesn't overflow. A test was added to dt_arith.c to check 2 conversions, from float to int where the float is INT_MAX, and from double to signed char where the double is SCHAR_MAX. Platforms tested: h5committest and fuss.
* [svn-r11346] Purpose:Quincey Koziol2005-09-031-413/+466
| | | | | | | | | | | | | | | | | Bug fix & code cleanup Description: Fix problem with detecting precision overflows in a more portable way. (I was depending on the compiler not removing some temporary variables, which was a bad bet... :-) Also, hoist the checking for the exception handling routine out of the inner conversion loop, which should speed up conversions which don't have an exception handling routine defined. Platforms tested: FreeBSD 4.11 (sleipnir) h5committest
* [svn-r11345] Purpose:Quincey Koziol2005-09-031-53/+114
| | | | | | | | | | | | | | | | Bug fix & code cleanup Description: Address most of datatype conversion exception handling bug that Ed Hartnett reported. (He's reported a different problem now, but we're closer at least). Also, condense exception handling #ifdef's into one location instead of spread out in so many places. Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
* [svn-r11332] Purpose: Minor Change to Macro NamesRaymond Lu2005-09-011-68/+68
| | | | | | | | | 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 Lu2005-08-301-67/+67
| | | | | | | | | | | | 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 Lu2005-08-291-75/+127
| | | | | | | | | | | | | | | | | | | | 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.
* [svn-r11254] Purpose: Bug fixRaymond Lu2005-08-171-3/+3
| | | | | | | | | | Description: In some macro definition, some constant values like D_MIN and D_MAX were not casted to the destination type. They may cause problems for some system like TFLOPS. Solution: Cast them to destination type. Platforms tested: fuss - very simple changes.
* [svn-r11245] Purpose:Quincey Koziol2005-08-131-326/+326
| | | | | | | | | | | | | | | | | | | | Code cleanup Description: Trim trailing whitespace, which is making 'diff'ing the two branches difficult. Solution: Ran this script in each directory: foreach f (*.[ch] *.cpp) sed 's/[[:blank:]]*$//' $f > sed.out && mv sed.out $f end Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
* [svn-r11233] Purpose: Bug fixRaymond Lu2005-08-111-1/+1
| | | | | | | | | | | Description: In the macro H5T_CONV_Xx_CORE definition, one line said "} else if (*((ST*)S) < (D_MIN)) {". It caused problem on TFLOPS because it defines LLONG_MIN as a hexadecimal value instead of decimal value. Solution: Changed the line to "} else if (*((ST*)S) < (DT)(D_MIN)) {" to avoid the problem. (Need to change other similar places when time permits.) Platforms tested: fuss - simple change.

* [svn-r10998] Purpose: Bug fix.Raymond Lu2005-06-291-1/+9
| | | | | | | | | | | | | Description: For the definition of the macro H5T_CONV_Xx_CORE, added a condition branch (else if (*((ST*)S) == (DT)(D_MAX))) which seems redundant. It handles a special situation when the source is "float" and assigned the value of "INT_MAX". A compiler may do roundup making this value "INT_MAX+1". However, when do comparison "if (*((ST*)S) > (DT)(D_MAX))", the compiler may consider them equal. Platforms tested: fuss - simple change.
* [svn-r10919] Purpose: Take Out An Unused FunctionRaymond Lu2005-06-141-391/+0
| | | | | | | | | | | 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:
* [svn-r10918] Purpose: Bug fixRaymond Lu2005-06-141-2/+2
| | | | | | | | Description: Fix the codes of last checkin(Bug #341). Some failures happened in daily test from last checkin. Try to fix them in this checkin. Platforms tested: modi4, mir, and tg-login2.
* [svn-r10785] Purpose:James Laird2005-05-231-2/+4
| | | | | | | | | | | | | | | | | Feature Description: Added "support" for UTF-8 character encoding. Solution: Wrote tests to check that UTF-8 can be used in a number of places in HDF5 (object names, data, etc.). These tests live in test/tunicode.c. Added a new UTF-8 character encoding for datatypes. Platforms tested: mir, modi4, heping Misc. update:
* [svn-r10731] Purpose: Bug fixRaymond Lu2005-05-051-0/+2
| | | | | | | | | Description: A user reported conversion of floating-point numbers returned some wrong value. It turned out a variable in H5T_conv_f_f() wasn't reset after being used for each element. See bug #356 for details. Solution: Simple reset it. Platforms tested: fuss; also tested with the program user provided. Very simple change.
* [svn-r10469] Purpose: Minor typo fixRaymond Lu2005-03-281-9/+9
| | | | | | | | | | Description: During last change, part of the code wasn't updated in copy and paste accordingly. It was in the exception handling of NaN in H5T_conv_f_f(). Solution: Corrected. Platforms tested: No test needed - trivial.
* [svn-r10456] Purpose: New way to do conversion test from floating-points to ↵Raymond Lu2005-03-261-39/+203
| | | | | | | | | | | | | | | | | | | integers. Description: The 6th step of changing conversion test. This checkin is only for conversion of special values from floating-points to integers. Solution: This test is seperated from regular value conversion. It reuses the same function test_conv_int_float() in test/dtypes.c. The source buffer of floating-point type is filled up with 8 special values, +/-0, +/-infinity, +/-QNaN, +/-SNaN. Also added 3 new conversion exception values H5T_CONV_EXCEPT_PINF, H5T_CONV_EXCEPT_NINF, H5T_CONV_EXCEPT_NAN, for floating-point special values positive infinity, negative infinity, and NaN. These values are for conversion exception callback function defined through H5Pset_type_conv_cb(). (Remember to update the document!) Platforms tested: h5committest

| | | | | | | | | | | | | types. Description: The 5th step of changing conversion test. This checkin is only for conversion of special values between floating-point types. Solution: This test is seperated from regular value conversion. It reuse the same function test_conv_flt_1() in test/dtypes.c. The source buffer of floating-point type is filled up with 8 special values, +/-0, +/-infinity, +/-QNaN, +/-SNaN. Platforms tested: h5committest, fuss, and modi4.
* [svn-r10266] Purpose: Bug fixRaymond Lu2005-03-221-31/+29
| | | | | | | | | | Description: The recent change of conversion between floating-point and floating-point types in dtypes.c have detected some bugs in H5T_conv_f_f in H5Tconv.c. Solution: This checkin is to fix these bugs. They happened in a few places in H5T_conv_f_f causing incorrect rounding, denormalization, etc. Platforms tested: h5committest and modi4
* [svn-r10113] Purpose: Bug fixRaymond Lu2005-03-011-0/+2
| | | | | | | | | | | Description: Condition check of macro H5_ULLONG_TO_FP_CAST_WORKS was accidentally taken out in last revision. This macro is defined for Windows because Windows doesn't support conversion from "unsigned long long" to any floating-point type. Solution: Added it back to H5T_conv_ullong_xxx() functions(xxx is any of "float", "double", or "long double"). Platforms tested: tested on Windows.
* [svn-r10087] Purpose: New feature and testRaymond Lu2005-02-251-2/+128
| | | | | | | | | | | 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-r10008] Purpose: Bug fixRaymond Lu2005-02-151-38/+22
| | | | | | | | | | | | Description: When hardware conversion between "long double" and integers was added to the library, the "double" used in H5T_CONV_Fx and H5T_CONV_xF for alignment wasn't big enough for "long double". New macros H5T_CONV_Lx and H5T_CONV_xL were added to use "long double" for alignment. But later it's found out the new macros were not necessary. Solution: Took out the new macros H5T_CONV_Lx and H5T_CONV_xL; change the "double" to "long double" for alignment in H5T_CONV_Fx and H5T_CONV_xF. Platforms tested: h5committest
* [svn-r10003] Purpose: Bug fixRaymond Lu2005-02-141-0/+4
| | | | | | | | | Description: At line 3564, the command H5T_bit_set(s, src.u.f.mpos, 1, FALSE) has unclear intention to me. Before I figure it out, move it to line 3590, where I think it should be. This did fix some data conversion. Platforms tested: fuss - already test it for v1.6.
* [svn-r9984] Purpose: New feature and testRaymond Lu2005-02-101-16/+671
| | | | | | | | | | 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-r9755] Purpose: New featureRaymond Lu2005-01-061-29/+25
| | | | | | | | | | | | | Description: Start to support software conversion between long double and all integers. Solution: No major changes to the algorithm. Changes to configure is to exclude SGI for long double to integers test because there're too many problems in their compiler. Platforms tested: h5committest, modi4, fuss, Teragrid, arabica 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 Lu2004-10-211-20/+20
| | | | | | | | | | | 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-r9329] James Laird2004-09-281-459/+459
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-r9053] Purpose:Quincey Koziol2004-08-081-0/+6
| | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | Purpose: Bug Fix Description: If an HDF5 file grows larger than its address space, it dies and is unable to write any data. This is more likely to happen since users are able to change the number of bytes used to store addresses in the file. Solution: HDF5 now throws an error instead of dying. In addition, it "reserves" address space for the local heap and for object headers (which do not allocate space immediately). This ensures that after the error occurs, there is enough address space left to flush the entire file to disk, so no data is lost. A more complete explanation is at /doc/html/TechNotes/ReservedFileSpace.html Platforms tested: sleipnir, copper (parallel), verbena, arabica, Windows (Visual Studio 7) Solution: Platforms tested: Misc. update:

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