Complete revamp of package initialization/shutdown mechanism in the library.
Each package now has a single init/term routine.
This new way should avoid packages being re-initialized during library
shutdown and is also be _much_ more proactive about giving feedback for
resource leaks internal to the library.
Introduces a new "module" header file for packages in the library
(e.g src/H5Fmodule.h) which sets up some necessary package configuration macros
for the FUNC_ENTER/LEAVE macros. (The VFL drivers have their own slightly
modified version of this header, src/H5FDdrvr_module.h)
Also cleaned up a bunch of resources leaks all across the library and tests,
along with addressing many warnings, as I encountered them.
Tested on:
MacOSX/64 10.10.5 (amazon) w/serial & parallel
Linux/64 3.10.x (kituo) w/serial & parallel
Linux/64 2.6.x (ostrich) w/serial

Bring r18542 from metadata journaling "merging" branch to trunk:
Bring new object header pin/unpin & protect/unprotect routines and
split-out object header chunk proxy changes from metadata_journaling branch to
"merging" branch, along with some other minor tweaks to clean up compiler
warnings, etc.
Also: clean up chunk protect/unprotect calls when allocating or freeing
space in a chunk, optimize metadata accumulator code to avoid some re-reading
of information from the file, refactor H5O_pin/H5O_unpin from way they are done
on the merging branch back to way they were previously done on trunk, other
minor code cleanups, etc.

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.

Description:
Factory free lists were formerly implemented as block free lists. This was
inefficient as factories can only be one size, and implementing them as blocks
(which can be variable size) wastedd computation and space. They have been
rewritten with a separate implementation, which is simlar to regular free lists
except they can be dynamically created and destroyed.

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".

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

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... )

Lots of performance improvements & a couple new internal API interfaces.
Description:
Performance Improvements:
- Cached file offset & length sizes in shared file struct, to avoid
constantly looking them up in the FCPL.
- Generic property improvements:
- Added "revision" number to generic property classes to speed
up comparisons.
- Changed method of storing properties from using a hash-table
to the TBBT routines in the library.
- Share the propery names between classes and the lists derived
from them.
- Removed redundant 'def_value' buffer from each property.
- Switching code to use a "copy on write" strategy for
properties in each list, where the properties in each list
are shared with the properties in the class, until a
property's value is changed in a list.
- Fixed error in layout code which was allocating too many buffers.
- Redefined public macros of the form (H5open()/H5check, <variable>)
internally to only be (<variable>), avoiding innumerable useless
calls to H5open() and H5check_version().
- Reuse already zeroed buffers in H5F_contig_fill instead of
constantly re-zeroing them.
- Don't write fill values if writing entire dataset.
- Use gettimeofday() system call instead of time() system when
checking the modification time of a dataset.
- Added reference counted string API and use it for tracking the
names of objects opening in a file (for the ID->name code).
- Removed redundant H5P_get() calls in B-tree routines.
- Redefine H5T datatype macros internally to the library, to avoid
calling H5check redundantly.
- Keep dataspace information for dataset locally instead of reading
from disk each time. Added new module to track open objects
in a file, to allow this (which will be useful eventually for
some FPH5 metadata caching issues).
- Remove H5AC_find macro which was inlining metadata cache lookups,
and call function instead.
- Remove redundant memset() calls from H5G_namei() routine.
- Remove redundant checking of object type when locating objects
in metadata cache and rely on the address only.
- Create default dataset object to use when default dataset creation
property list is used to create datasets, bypassing querying
for all the property list values.
- Use default I/O vector size when performing raw data with the
default dataset transfer property list, instead of querying for
I/O vector size.
- Remove H5P_DEFAULT internally to the library, replacing it with
more specific default property list based on the type of
property list needed.
- Remove redundant memset() calls in object header message (H5O*)
routines.
- Remove redunant memset() calls in data I/O routines.
- Split free-list allocation routines into malloc() and calloc()-
like routines, instead of one combined routine.
- Remove lots of indirection in H5O*() routines.
- Simplify metadata cache entry comparison routine (used when
flushing entire cache out).
- Only enable metadata cache statistics when H5AC_DEBUG is turned
on, instead of always tracking them.
- Simplify address comparison macro (H5F_addr_eq).
- Remove redundant metadata cache entry protections during dataset
creation by protecting the object header once and making all
the modifications necessary for the dataset creation before
unprotecting it.
- Reduce # of "number of element in extent" computations performed
by computing and storing the value during dataspace creation.
- Simplify checking for group location's file information, when file
has not been involving in file-mounting operations.
- Use binary encoding for modification time, instead of ASCII.
- Hoist H5HL_peek calls (to get information in a local heap)
out of loops in many group routine.
- Use static variable for iterators of selections, instead of
dynamically allocation them each time.
- Lookup & insert new entries in one step, avoiding traversing
group's B-tree twice.
- Fixed memory leak in H5Gget_objname_idx() routine (tangential to
performance improvements, but fixed along the way).
- Use free-list for reference counted strings.
- Don't bother copying object names into cached group entries,
since they are re-created when an object is opened.
The benchmark I used to measure these results created several thousand
small (2K) datasets in a file and wrote out the data for them. This is
Elena's "regular.c" benchmark.
These changes resulted in approximately ~4.3x speedup of the
development branch when compared to the previous code in the
development branch and ~1.4x speedup compared to the release
branch.
Additionally, these changes reduce the total memory used (code and
data) by the development branch by ~800KB, bringing the development
branch back into the same ballpark as the release branch.
I'll send out a more detailed description of the benchmark results
as a followup note.
New internal API routines:
Added "reference counted strings" API for tracking strings that get
used by multiple owners without duplicating the strings.
Added "ternary search tree" API for text->object mappings.
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)

Bug fix & code cleanup
Description:
Hyperslab code for collapsing dimensions was incorrectly collapsing
selections inappropriately when the fastest changing dimension couldn't
be collapsed.
Also add some more assertions which will make similar bugs easier to find.

Description:

platforms.
Additionally, I improved a lot of the error cleanup code in many routines.

Code cleanup
Description:
Broke the FUNC_ENTER macro into several macros, with more specialized
uses (which followup mail will describe). This was designed to move
most/all of the checks which could be done at compile time to that point,
instead of needlessly performing them (over & over :-) at run-time.
This reduces the library's size (and thus staticly linked binaries) and
has a minor speedup effect also.
Platforms tested:
IRIX64 6.5 (modi4) with parallel & FORTRAN enabled, and additional testing
on FreeBSD and Solaris immediately after the checkin.

Code cleanup.
Description:
Took Robb's recent ideas for improving the FUNC_ENTER/FUNC_LEAVE macros
equivalents in the SAF library and adapted them to our library. I added
an additional macro which is equivalent to FUNC_ENTER:
FUNC_ENTER_NOINIT - Has the API tracing code, etc. from FUNC_ENTER but
none of the library or interface initialization code. This is to
be used _only_ for static functions and those which explicitly
cannot have the library or interface initialization code enabled
(like the API termination routines, etc.).
This allowed many more of the functions in the library [but not all yet :-(]
to be wrapped with FUNC_ENTER[_NOINIT]/FUNC_LEAVE pairs.
It also reduced the size of the library and executables (by cutting out a
bunch of code which was never executed), I'll e-mail the exact results when
I've finished editing it.

Feature improvement
Description:
Re-write how the free-list headers were used, to reduce the amount of space
added to each malloc request. Reduced header for array and block free
list items from 24 bytes to 8 bytes and eliminated the header for fixed-size
free list items entirely. This should reduce the amount of memory that the
library uses.

Code speedups, etc.
Description:
Bring in new algorithms and data structures for dealing with hyperslabs.
This speeds up the hyperslab I/O for non-regular hyperslabs by a huge
amount.
Currently, the new API functions are ifdef'ed out, pending discussion
and consensus approval.
Platforms tested:
FreeBSD 4.4 (hawkwind)

Code cleanup (sorta)
Description:
When the first versions of the HDF5 library were designed, I remembered
vividly the difficulties of porting code from a 32-bit platform to a 16-bit
platform and asked that people use intn & uintn instead of int & unsigned
int, respectively. However, in hindsight, this was overkill and
unnecessary since we weren't going to be porting the HDF5 library to
16-bit architectures.
Currently, the extra uintn & intn typedefs are causing problems for users
who'd like to include both the HDF5 and HDF4 header files in one source
module (like Kent's h4toh5 library).
Solution:
Changed the uintn & intn's to unsigned and int's respectively.

Code clean/bug fix
Description:
H5FL (free-list manager) code currently is taking an hsize_t as the size
of a memory block to allocate. On many machines, the size of an hsize_t
is greater than the size of a size_t, potentially leading to incorrect
memory allocations in rare circumstances.
Solution:
Changed hsize_t parameters and variables to size_t.

FreeBSD 4.3 (hawkwind)

Bug fix for Pablo integration
Description:
Several API functions were using FUNC_ENTER, without using FUNC_LEAVE,
HRETURN or HRETURN_ERROR to leave the function. (Using "plain" 'return'
statements instead).
Solution:
Changed return statements to FUNC_LEAVE, HRETURN or HRETURN_ERROR, as
appropriate.

FreeBSD 4.3 (hawkwind)

Update
Description:
Changed
#include <hdf_file.h>
construct to
#include "hdf_file.h"
so that the GNU compiler can more easily pick up the dependencies
which it places in the .depend and Dependencies files. Also
regenerated the Dependencies to go along with this.
Platforms tested:
Linux

Code cleanup.
Description:
Fixed _lots_ (I mean _tons_) of warnings spit out by the gcc with the
extra warnings. Including a few show-stoppers for compression on IRIX
machines.
Solution:
Changed lots of variables' types to more sensible and consistent types,
more range-checking, more variable typecasts, etc.
Platforms tested:
FreeBSD 4.2 (hawkwind), IRIX64-64 (modi4)

Bug fixes
Description:
All tests were core=dumping in IRIX64. The bug is in Generic
property list creation in which malloc asked for 2*64-1 bytes
due to coding bug. The object creation failed but the return
code was not checked. Program eventually crashed.
Solution:
H5F.c:
Check the return code from new file object creation and flag
error accordingly.
H5FL.c:
H5FL_arr_free is a replacement for H5MM_xfree which accepts
null value as a legal argument value. H5FL_arr_free assert
on it. Since other parts of the code have been passing null
value to H5MM_xfree, H5FL_arr_free must accept it too until
all the calling routines are changed to not pass Null.
H5P.c:
some routine passes in 0 as the hashsize value which is uintn.
The expression (hashsize-1) underflows to the largest unsigned
int for some machines. Thus the calloc failed. Cast hashsize
to unsigned int first (this assumes hashsize stays within the
signed int data range.
H5Smpio.c:
Added the extra parameter because the H5FD_write has been redefined.

IRIX64 -64 and -n32
