(LK & QK) r18237: fixed coverity 133: if (NULL==_dest && NULL==ret_value && NULL != dest) H5MM_free(dest); r18238: Fix coverity items 421 and 422. Added assertion that the heap's free list is NULL when entering H5HL_fl_deserialize, guarateeing that the free list will always be linked in even on failure. r18239: Fix coverity item 268. Changed H5MM_xfree(read_buf) to read_buf = H5MM_xfree(read_buf) so that read_buf isn't manipulated after it's been freed. r18241: coverity fix: use correct free functon H5FL_FREE()from the previous fix r18242: Coverity fix 139: Free dst correctly in H5O_sdspace_copy(). r18243: Fix Coverity issue #417 by checking for NULL return value from setup_cache() (LK & QK) r18244: Coverity Fix 132: free dest correctly in H5O_efl_copy() r18245: Issue 121: H5S_hyper_make_spans() cannot deal with counts of 0. However, H5Sselect_hyperslab() API does allow a count of 0. Therefore, simply throw an error if this function encounters a count of 0. r18246: Check file_ptr to address coverity issue # 418 r18247: Fixed coverity 113: if (sequence) H5MM_xfree(sequence); r18248: Coverity issue #414 by checking for NULL return from setup_cache() (LK & QK) r18249: fixed coverity 274: moved H5FL_FREE(H5A_t, attr); to a line above so that if attr is null, it will not free it. r18250: Fix coverity issue #86. Check return of malloc function to ensure non-null before continuing. Tested on: Mac OS X/32 10.6.2 (amazon) w/debug & production) (h5committested in daily tests on branch)

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) debug & prod

Fixed memory leak on error in print_enum in H5LT.c. r17993: (r17992 was not a Coverity change) Close Coverity issue #206: inconsistently checking whether dt->shared was non-NULL after H5T_alloc() returned a valid 'dt' value (which should guarantee that dt->shared is valid). r17994: Fix Coverity item 149. Fixed file handle leak on error in H5FD_stdio_open. r17995: Fixed Coverity issues 154 to 161: Added H5MP_close routine to error handling in the event *mp has not been freed before error. r17996: Close Coverity issue #126: potentially leaking merged_spans on routine failure. r17997: Fix Coverity items 147 and 148. Fixed resource leaks on error in H5FDloc.c. r17998: Coverity issue 269-272: Added integer result variable to functions that could return negative. Assigned to unsigned after checking. Added H5E_BEGIN_TRY block around H5Tclose and removed H5E_THROW in the catch block. Checked buffer is NULL before free. Changed HGOTO_ERROR outside of the if block to H5E_THROW. r17999: Close Coverity issue #127: release temporary spans in more generic manner. (Also add error checking to previous fix) r18000: Resolved Coverity issues 211 and 212 in H5T.c. Added comments to ignore Coverity warning regarding not checking pointer for NULL, as we are using an assert which catches the issue. r18001: Fix Coverity item 146. Fixed resource leak on error in H5O_layout_copy. r18002: Fix Coverity items 143 and 145. Fixed resource leaks on error in H5D_compact_copy and H5D_contig_copy. r18003: Close Coverity issue #192: close file on error r18004: Fix Coverity issue #125: release temporary spans on error r18005: Resolved Coverity issues 5, 25, and 83 (in H5T.c): Separated embedded functions in order to check for NULL on return of H5I_object before passing into H5T_copy. Check to see if new_dt is NULL within error handling before dereferencing it. Ignore Coverity's dead code warnings as the checks that lead to the code are machine dependent. r18006: Coverity 63,70,73: Checked result of function before assigning to an unsigned variable. r18007: Coverity 78,79: added continue statement if H5Pget_filter2 returns negative. r18008: Fixed Coverity issue # 138: Added support in error handling to free dst pointer (if allocated) on error. r18009: Whitespace & coding style cleanup Tested on: Mac OS X/32 10.6.2 (amazon) w/debug & production (h5committested on trunk)

Description: Added a new field 'app_count' to H5I_id_info_t struct, to track the reference count on an id due to the application. the old 'count' field tracks the total. Generally any id visible to the application gets placed in app_count. Added app_ref boolean parameter to H5I_inc_ref, H5I_dec_ref, H5I_register, H5I_clear_type, and a few other functions, to specify whether the operation(s) being performed on the id(s) are due to the application (TRUE) or not (FALSE).

* [svn-r10951] Purpose:Quincey Koziol2005-06-181-15/+63
| | | | | | | | | | | | | | | | | Bug fix Description: Hyperslab selections that had a selection offset and were applied to a chunked dataset could get into an infinite loop or core dump if the same selection was used multiple times, with different selection offsets. Solution: "Normalize" the selection with the selection offset, generate the selections for the chunks overlapped and then "denormalize" the selection.

* [svn-r10832] Purpose:Quincey Koziol2005-05-311-23/+124
| | | | | | | | | | | | | | | | | Bug fix Description: Fix problems with hyperslab operations with hyperslabs that have count == 0 or block == 0 values. (bugzilla #294) Solution: Detect zero sized selections and translate into appropriate action on the current hyperslab, rather than go through the formality of generating span trees with zero-sized spans, etc. Platforms tested: FreeBSD 4.11 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r10578] Purpose:Quincey Koziol2005-04-081-55/+82
| | | | | | | | | | | | Code optimization Description: Reduce overhead for common case of stride==NULL and block==NULL for H5Sselect_hyperslab() calls. Platforms tested: FreeBSD 4.11 (sleipnir) Solaris 2.9 (shanti)

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

| | | | | | | | | | | | | | | | | | | bug fix Description: The irregular hyperslab span_tree implementation inside H5S_hyper_add_span_element_helper updating the high bound of the span, but forget updating the number of element of the span. New routine obtain_derived_datatype catches the bug. Solution: Updating the number of element of the span as well. Platforms tested: Linux 2.4 and AIX 5.1, both with parallel enabled. Misc. update:
* [svn-r8987] Purpose:Quincey Koziol2004-08-021-1/+1

* [svn-r8731] Purpose:Quincey Koziol2004-06-231-71/+37
| | | | | | | | | | | | | | | 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. Platforms tested: FreeBSD 4.10 (sleipnir) w/gcc34 h5committest
* [svn-r8690] Purpose:Quincey Koziol2004-06-151-1/+16
| | | | | | | | | | | | Code optimization Description: Be smarter about copying hyperslab selection data and avoid memcpy() calls. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8677] Purpose:Quincey Koziol2004-06-141-59/+56
| | | | | | | | | | | | | | | | | | | Code cleanup & optimization Description: Remove old structures that used a union to store information about the dataspace extent and just store the information directly in the dataspace extent itself. Remove ifdef'd references to permutation ordering in dataspaces. We'll definitely need more than this code if/when we implement this feature. Change allocation of dataspace information from calloc() to malloc(). Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8673] Purpose:Quincey Koziol2004-06-131-202/+247
| | | | | | | | | | | | | | | | | | Code optimization Description: Revised dataspace selections to use a more "object oriented" mechanism to set the function pointers for each selection and selection iterator. This reduces the amount and number of times that dataspace selection info has to be copied. Additionally, change hyperslab selection information to be dynamically allocated instead of an inline struct.

* [svn-r8544] Purpose:Quincey Koziol2004-05-201-47/+9
| | | | | | | | | | | | | | Code optimization Description: Expand the use of macros to inline trivial function pointer lookup and calls to reduce the overall number of functions invoked during normal operation of the library. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.9 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8520] Purpose:Quincey Koziol2004-05-131-16/+13
| | | | | | | | | | | | Code optimization Description: Don't make a separate allocation for the selection offset - incorporate it into the selection structure as a fixed size array. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.9 (sleipnir) w/parallel
* [svn-r8513] Purpose:Quincey Koziol2004-05-131-28/+108
| | | | | | | | | | | | Code optimization Description: Defer creating the span trees for hyperslab selections until they are actually needed (which may be never, in certain circumstances). Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.9 (sleipnir) w/parallel
* [svn-r8496] Purpose:Quincey Koziol2004-05-081-3/+14
| | | | | | | | | | | | | Code optimization Description: Further reduce the number of copies we make of a hyperslab selection for chunked I/O, especially when we are only going to throw the old selection away for a new one. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.9 (sleipnir) w/parallel
* [svn-r8460] Purpose:Quincey Koziol2004-05-011-21/+19
| | | | | | | | | | | | | | | Code optimization Description: Move the element size for the selection into the selection iterator instead of always passing it as a parameter. Also, eleminate another 64-bit multiply for "all" selections. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.9 (sleipnir) too minor to require h5committest
* [svn-r8457] Purpose:Quincey Koziol2004-05-011-35/+31
| | | | | | | | | | | | | Code optimization Description: Stop straddling the line and always use elements instead of bytes to determine how how I/O to perform on a selection. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.9 (sleipnir) too minor to require h5committest
