* [svn-r22646] Description:Quincey Koziol2012-08-081-3/+3
| | | | | | | | | Changes resulting from Klocwork static analysis tool, from Mark Miller @ LLNL (miller86@llnl.gov). Tested on: Mac OS X/64 10.7.4 (amazon) w/debug, C++ & FORTRAN, using gcc 4.7.x (too minor to require h5committest)
* [svn-r22287] Description:Quincey Koziol2012-04-161-57/+57
| | | | | | | | Clean up more FUNC_ENTER/FUNC_LEAVE macros and move H5D & H5T code toward the final design (as exemplified by the H5EA & H5FA code). Tested on: Mac OSX/64 10.7.3 (amazon) w/debug & parallel
* [svn-r21342] Issue 7674 - clang compiler with -fcatch-undefined-behavior ↵Raymond Lu2011-08-311-6/+12
| | | | | | | | | -ftrapv discovered several problems in the test suite. One of them is in the INIT_INTEGER macro definition in dt_arith.c. It complained about line 150 where it tried to subtract 1 from the negative minimal value of "int", causing it to overflow (or underflow). So I revised the code to avoid it. Tested on jam, koala, linew, and Mac OS Lion with CLANG compiler.
* [svn-r19696] Bug 2008 - IBM Power6 Linux uses special conversion algorithms ↵Raymond Lu2010-10-281-0/+32
| | | | | | | | | | | to convert some values from long double to (unsigned) long and from (unsigned) long to long double. I added tests in configure.in to detect these algorithms. Before I can figure out them, I disable the tests in dt_arith.c. There are property changes to tools/misc, config, and Makefile.am when I brought the fix from 1.8. Tested on jam, heiwa, amani, IBM Power6 Linux machine in Holland (huygens.sara.nl).

(Would never have been executed otherwise) r18139: Fix coverity item 58. Moved code related to displaying the parent of a repeated group to the else(isRoot) section, as the root group has no parent. r18140: 218: Initialized ret_value variable to -1. Because of throw Exception in default case of switch, the coverity problem would not have executed anyway. Good pratice is to initialize variables. r18141: Fix coverity item 92. Added code to H5E_register_class to free cls in case of an error. r18142: Fix coverity item 91. Added code to H5E_create_msg to free msg in case of an error. r18143: fixed issue 14, took away "if" and used #ifndef_xxx. r18144: Fix coverity item 110. Added code to H5Eget_minor to free msg_str in case of an error. r18145: fixed coverity #18 removed "aligned", it is always NULL. r18146: Fix coverity item 109. Added code to H5Eget_major to free msg_str in case of an error. r18147: Fixed coverity #81 and #82, Check for bad pointer(s), but can't issue error, just leave r18148: Fix coverity item 97. Added code to H5FD_fapl_open to free copied_driver_info in case of an error. r18149: Fix coverity item 96. Added code to H5FD_dxpl_open to free copied_driver_info in case of an error. r18150: Fix Coverity issue #29: Protected cache_ptr dereferences with "if(pass)" block r18151: Fix coverity item 93. Added code to H5FL_fac_init to free factory and new_node in case of an error. r18152: Fix coverity items 98 and 99. Added code free allocated space in case of error. r18155: 124: Freed head pointer before jumping to done. There was no error handling block and normal exit used same path out. 120-123: Freed list of lists in error handling block. r18156: Fix coverity issues 179, 180, 181, 182, 183, 184, 186, 320, 407.

When an error occurred while copying a linked list in H5S_point_copy, the library would not free the partially allocated list. Added code to free the list in this case. r18078: Correct Coverity issue #2 by removing impossible to reach code. r18079: Correct #3 by removing impossible to reach code. r18080: Correct Coverity issue #4 by removing impossible to reach code. r18081: fix coverity 26 , check (dblik->parent) before calls H5HF_man_iblock_detach(). r18082: Fixed coverity issues 321 and 316. 321: freed sm_buf in error handling to remove resource leak. Also set sm_buf to NULL after other instances in which it is freed to prevent double free. 316: initialized nmembs to 0. r18083: Correct Coverity issue #6 by removing debugging knob from error reporting code. r18084: Fix coverity item 269 + others. When a error occurred in a function using the h5tools error framework, the "past_catch" variable would not be set to true because that statement was before the label that goto jumped to. This could cause a failure in the cleanup section to go back to the start of the section, freeing variables twice, etc. Moved the label infront of past_catch=TRUE. r18085: fixed coverity #27, check if (heap) before use heap->obj.... r18086: fixed coverity #28, check curr_span not null before use it at if(curr_span && (io_bytes_left==0 || curr_seq>=maxseq)) r18087: Correct Coverity issue #7 by cleaning up correctly on error r18088: Correct Coverity #8 by removing unchanged variable checking code. r18089: Correct Coverity issue #9 - remove impossible to reach code. r18090: Correct Coverity issue #11 by removing impossible to reach code. Also clean up some minor style issues. r18091: Fix coverity items 314 and 318. Changed the improper assertion of the return value of a library function to a check, and a return(void) on failure. r18092: Fix coverity item 70. Changed the improper assertion of the return value of a library function to a check, and a return(void) on failure. r18093: Correct Coverity issue #12 by removing dead code. r18094: Correct Coverity issue #16 by removing debugging code. r18095: Fixed coverity issue # 271. Removed redundant checking and freeing of sm_buf1 and sm_buf2. r18096: Correct Coverity issue #17 by refactoring test to remove dead code. Also, removed previous "coverity" statements in comments, we'll review those issues again and see if we can figure them out, now that we have more experience with Coverity. Tested on: Mac OS X/32 10.6.2 (amazon)

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 Lu2006-06-201-3/+19
| | | | | | | | | | | | | | | 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.

* [svn-r11415] Purpose: Internal design change.Raymond Lu2005-09-141-1/+1
| | | | | | | | | | | | | | | | | 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 Lu2005-09-121-0/+226
| | | | | | | | | | | | | | | | | | 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-r11355] Purpose: A new API function and its test.Raymond Lu2005-09-061-0/+63

* [svn-r11345] Purpose:Quincey Koziol2005-09-031-1/+1

(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-r11311] Purpose: New features.Raymond Lu2005-08-291-43/+43
| | | | | | | | | | | | | | | | | | | | 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-r11245] Purpose:Quincey Koziol2005-08-131-202/+202
| | | | | | | | | | | | | | | | | | | | 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-r11144] Purpose:Quincey Koziol2005-07-231-22/+104
| | | | | | | | | | | New port Description: Elena asked me to check in her NEC SX-6 work, so here it is! :-) Platforms tested: FreeBSD 4.11 (sleipnir) NEC SX-6 (by Elena)
* [svn-r11087] Purpose: Bug fix.Raymond Lu2005-07-191-90/+109
| | | | | | | | | | | | | | Description: When converting floating-point numbers to integers and the values of floating-point number are greater than the maximal value of integer, Cray X1 generates floating exception. Solution: Added a test in configure to detect Cray X1's exception. Set a flag to indicate the machine that can handle overflow converting all floating-point to all integer types. This flag should be set for all machines, except for Cray X1 where floating exception is generated when the floating-point value is greater than the maximal integer value. Platforms tested: Cray X1 and h5committest.
* [svn-r10962] Purpose: Solve the Difference of Compiler and LibraryRaymond Lu2005-06-201-2/+56
| | | | | | | | | | | | Description: In this data conversion test, from floating number to floating number, when the source is bigger than the destination, overflow may happen. The library assign INFINITY while compiler's behavior is undefined. A compiler like SGI assigns the maximal value for the destination. Solution: When this situation occurs, simply check if the destination is INFINITY instead of comparing values. Platforms tested: modi4 and h5committest.
* [svn-r10931] Purpose: Adjust Test Program and RenameRaymond Lu2005-06-171-0/+4672
Description: Renamed test/dt_atomic.c to test/dt_arith.c(an abbreviation of "arithmetic data types") to better describe the program. This checkin broke down into three sections when the floating-point numbers are the source, normalized, denormalized, and special values. If there's any difference of destination values, only normalized value test reports failure. The other 2 report only as warning. Platforms tested: h5commitest and fuss Misc. update: MANIFEST
