bb294c2b1e [svn-r20108] Purpose:
Fixing Bug 2092 - h5dump does not display index for a dataset

Description:
    h5dump skip displaying array indices every certain number when the 
    array type dataset is relatively big. The certain number varies 
    according to the size of each array. 
    This checkin fix the skipping array indices problem. This fix also
    correct indentation of the dataset data output.

Bring changes from Coverity branch to trunk:

r19975:
Fixed potential mem leak at H5O_attr_open_by_name

r19980:
Fix coverity issue 792.
Free tmp_env_prefix in H5Lexternal.c line 365 if it is not NULL but its contents are 0 when it goes out of scope.

r20039:
Eliminate warnings about nested extern and implicit declarations of parallel_print and address Coverity defects 712-781 by #including h5tools_utils.h in h5diff_array.c, h5diff_attr.c, h5diff_dset.c and h5diff_util.c.

r20046:
Purpose: Address TOCTOU warnings in h5jam and h5unjam

Description: Coverity is afraid that the state of the input file could change
between the call to stat() and the call to open().  This is called a time-of-
check time-of-use (TOCTOU) vulnerability.  Modified stat calls to fstat which
uses an open file pointer so it (hopefully) won't complain any more.

r20047:
Addressed coverity issues 135-137, 462-464.  Local pointers that needed to be freed in case of error were moved out of a switch statement in src/H5Tnative.c, set to NULL, and checked before freeing.

a6d5fa2c7d [svn-r20061] Description:
Bring changes from Coverity branch to trunk:

r19930:
Fix memory leaks involving VL attributes in h5repack and h5diff.  The buffers in
copy_attr and diff_attr were not checked for the presence of a vlen before being
freed, and vlen storage was never reclaimed.  Added checks and calls to
H5D_vlen_reclaim().

r19933:
Purpose: Fix memory leak in H5L_move_cb()

Description: H5L_move_cb copied the source link using H5O_msg_copy() but freed
it manually using H5MM_xfree().  Since H5O_link_copy allocates the link using
H5FL_MALLOC, this causes the link to be allocated from the free list but is
never put back on the free list when it is freed.  This prevents the link free
list from shutting down properly.  Modified H5L_move_cb() and H5L_move_dest_cb()
to free the link properly using H5O_msg_free().

Fix resource leaks by freeing string created by HD5f2string

Bug 2089 - GMQS: h5diff segfault on a compound dataset with fixed length + 
    vlen string type order

Description:
    This is fix for the segfault when h5diff compares a compound dataset with 
    combination of fixed length string types and vlen string types in certain 
    orders. Optimized vlariable length string handling codes. The fix is 
    referred from h5dump handling vlen strings. 
    For testing, several compound datasets were added with various combinations.
    Previous failed cases:
     - Vlen string, Fixed length string, Vlen string, Fixed length string
     - Fixed length string, Fixed length string, Vlen string, Vlen string
     - Fixed length string, Vlen string, Fixed length string, Vlen string

Changed subset_t structure from holding hsize_t pointers to holding new subset_d pointers, which hold the original hsize_t pointer + len. this len is then checked against dataset ndims in the handle_dataset function of h5dump.

eee9ca47a1 [svn-r19202] [BZ1953]implementation for the proposed changes suggested by the "h5dump_output_option" RFC. This required that the region reference code be duplicated and reduced to allow the do_bin_output() function to understand region references. The container type-id also needed to be propagated into the do_bin_output() function and functions referenced (render_bin_output*).
Existing tests tested the binary function, so only one test was added to test the region reference generated file.

Improve configure's large-file support control.

Description:

    Modified configure to now attempt to add defines necessary for
    supporting largefiles on all systems, instead of solely on linux. This 
    is in response to user requests to enable largefile support on Solaris 
    by default, as well as to give extra control on AIX (instead of just 
    jamming the necessary flag into the config files).

    The old --enable-linux-lfs flag has been removed in favor of the 
    --enable-largefile flag (enabled by default), which can be used on all
    platforms.

    On systems where large files cannot be supported in this manner,
    configure will report as such.

Autotool Upgrade / Libtool Bug Fix

Description:

    Updated autotools referenced in bin/reconfigure as follows:

    Autoconf 2.64 --> Autoconf 2.65
    Automake 1.11 --> Automake 1.11.1
    Libtool 2.2.6a --> Libtool 2.2.6b-mcg

    The referenced libtool version is a custom version of 2.2.6b. It 
    has been tweaked to fix a bug in libtool that occurs
    when using PGI 10.0 compilers. A check incorrectly categorizes
    the C++ compiler as version 1.0 instead of 10.0, and the link
    line is subsequently set up incorrectly and fails to compile.

    A patch has been made available and will be included in the next
    release of libtool, but in the meantime I've applied the patch to a custom
    installation as indicated above. This bin/reconfigure now references
    the custom installation, and the resulting configure script will correctly
    categorize the PGI 10.0 C++ compiler.

    Ran bin/reconfigure to regenerate configure and makefiles.

Tested:

79cd5838d1 [svn-r18164] Purpose:
Add a feature to compare through links. Relate to bugzilla report 1754.

Description:
    Currently, h5diff command only compares the name(path) of target object 
    not the actual data. With this feature, h5diff will go through the link(s) 
    and figure out the actual object at the end of the link and compare data 
    if exist. Internally we have hard-link, soft-link, external-link (as part 
    of user_defined-link). This feature will provide a user transparent 
    experience when comparing link objects as the user can specify any of 
    those 3 type of links to be compared in any combination.

Tested on Jam.

bb25c85e79 [svn-r18159] Description:
Bring Coverity fixes from 1/22/10 session to trunk:

r18137:
219: Initialized hid_t to -1 and added close to error block.
189-191: Initialized line to NULL and added free line, and close fp to error block.

r18138:
19: Moved code block for printing that the number of enums is empty to the error block. (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.  These were resource leak issues where allocated memory was not freed, generally in the case of tests that failed.

3c5dc1a808 [svn-r18134] Purpose:
Additional fix relted to the fix of bug1672.

Description:
    The fix of bug1672 caused some changes of output which required modifying
    some test cases.  After some discussion, restoring the changes of the test 
    cases was decided.  After many experiments for the solution, this fix was 
    made so the code which improved performance can stay.

Tested on Jam.
